Among other interesting mechanical appli- ances shown at the Engineering and Metal Trades Exhibition, now being held in Eng- land, a band-saw for cutting cold iron and steel, of which we annex an engraving, is | worthy of further notice. The table of the machine is 2 feet 8 inches long by 2 feet 4 inches wide, and has a variable self-acting feed motion of 2 feet, with a self-acting stop motion. As illustrated in our engraving, the requisite speed of feed for cutting materials of different thicknesses, varying from 3% inch to 10 inches, may be obtained by means of suitable change-wheels. The saw pulleys are 40 inches in diameter, and the periphery of each is covered with leather so as to pre- vent the saw, which is about % inch wide, ~ slipping. The lower pully is cast with a spur-wheel on its outer rim, and this is driven by a pinion on one end of the cone pulley shaft. The upper pulley, on the other hand, is mounted in a bearing in a vertical | slide, the latter being provided with ascrew adjustment so as to accommodate various lengths of saws and to provide the necessary | tension. The appliance, which is of English manufacture, is said to have met with grati- fying success, and is now extensively em- | ployed in arsenals, gun factories, locomotive | shops and the like, for cutting out gun car- riages, tender and wagon framings, ship plates, &e. Le — Cranes—A Study of Types and Details.* BY HENRY R. TOWNE, STAMFORD, CONN, In the study of any special class of ma- chines it is often conducive toa better under- standing of the subject clearly to enumerate the several types or forms in which -he ma- chine is used, and also to consider each of its more important details separately, rather than in their combination with other ele- ments of the mechanism. It is proposed in the following pages thus to treat the subject of cranes. The only English text-books de- scriptive of cranes are Glynn’s, which treats of English practice in crane building as it existed more than 30 years ago, and sundry catalogues published by English dealers in machinery as a means of advertising the products of the various builders of cranes for whom they act as selling agents. The practice represented in the former is now al- most obsolete, by reason of the improve- ments which have been effected, and the letter consist of little but a series of pictures of various cranes, without descriptive text, and with no information as to the details of their construction. The building of cranes has long been recognized in Europe as one of the most important subjects in the field of mechanical engineering, and cranes of many forms are there seen applied to an almost infinite variety of uses. In America, on the contrary, cranes are but little used or ap- preciated —in comparisou, at least, with the extent of their application in European countries. It is the purpose of this paper to present to American readers a brief classi- fication and description of the most impor- tant types of cranes, aud a similarly brief study of the more important elements enter- ing into their construction, the object of the latter inquiry being to determine, if possi- ble, the best forms of elements to be adopted. With a better knowledge of crane construc- tion will surely come a better appreciation of their economy and value as labor-saving machines. In hundreds of mills and work- shops heavy material is now being moved and handled by manual labor at an expense so much in excess of the cost of doing the same work far more rapidly and conven- iently by cranes, that the saving effected by the latter would yield an annual profit of from 20 to 50 per cent. upon their first cost, while in many cases this outlay would be entirely repaid by the economy of one year’s use. CLASSIFICATION OF CRANES. A hoist is a machine for raising and lower- ing weights. A crane is a hoist with the added capacity for moving the load in a lat eral or horizont | direction. All cranes, therefore, are provided with hoisting mechanism, and, in addition, must be capable of moving the load in one or more horizontal directions. This second function is effected in some types of cranes by simply p.ishing the load, in others by the operation of a distinct mechanism. Cranes are most clearly classified by refer- ence to their modes of transferring their aan horizontally, and, thus considered, are found to divide themselves into the follow ing groups, viz.: 1. Rotary.—In which the load is revolved around a fixed center, such as a mast or column. 2. Rectilinear.—In which the load is moved in straight lines, in one or more directions. Both types of cranes are subdivided iuto two general classes as to their movements, viz; {4.) Fived.—When the supporting mem- bers are fixed in some permanent location. (B.) Movable.—When the crane as a whole can be moved about. And into four other general c lasse *s as to their source of motive power, viz. ‘a.) Hand —When the motions, aa ver- tical or horizontal, are effected by manual power. ' * Read at the Cleveland mee ting of the Ameri an Society of Mechanical E ogineers, (b.) Power.— When the motions are effected by power derived from line shafting driven by a stationary engine or other fixed motor. (c.) Steam.—When the motive power is derived from a steam engine attached di- rectly to the crane itself and moving with it. (d.) Hydraulic.—When the motive power consists of hydraulic pressure obtained from a pump or accumulator, and carried to the crane by pipes. A further distinction is covered by the term locomotive, which is applied to cranes (usually of the rotary type) which are capable of pro- pelling themselves on a roadw ay or seal Rotary cranes comprise the following prin cipal types, viz. : 1. Swing Cranes.—In which the central mast is pivoted to the floor and roof of the building, and the load is suspended from a block fixed at the outer end of an arm pro jecting horizontally from the mast, the only | horizontal motion being one of rotation. 2. Jih Cranes.—In which the central mast is pivoted to the floor and roof of the build- ing, and the load is suspended from a trolly traveling in and out upon an arm or jib projecting laterally from the mast 3. Column Cranes.—Which of a jib crane constructed to revolve around or consist upon a fixed column forming the support of | a building or floor. 4. Pillar Cranes.—In which the central column or pillar is entirely supported by a heavy foundation built at its base, and the load is suspended from a boom projecting from the pillar and revolving with it or around it. 5. Derrick Cranes.—Which consist of a jib crane for yard use, the upper end or pivot of the mast being held in position by guy rods or stays, instead of by cake hment to a roof or ceiling. 6. Walking Cranes.—Which consist of a pillar or jib crane mounted on wheels, aitened to travel by power or by hand upon one or more rails. 7. Locomotive a pillar-crane mounted on wheels, and pro vided with a steam engine and boiler, the power of which is available for operating the crane and for propelling it upon its tracks BAND-SAW i and | Cranes.—Which consist of | Rectilinear cranes comprise the following | in one of two ways, viz.: 1. By principal types : 1. Bridge Cranes.—In which a fixed bridge spans an opening, and the load is suspended from a truck or trolly capable of moving across the bridge. 2. Tram Cranes.—In which a truck or short bridge, from which the load is sus pended, is arranged to travel longitudinally upon a pair cf overhead rails, but is without capacity for transverse motion. 3. Traveling Cranes.—In which a rectan- gular space is provided with overhead tracks upon two of its opposite sides, and is spanned by a bridge arranged to travel longitudinally upon these tracks, the load being ‘suspended from a truck or trolly capable of moving transversely across the bridge, so that the load may be moved to or from any point within the entire rectangle, a= a Fal 1) me si i HHH H) aH Ih f i ' Ny HM Ha i Mit i Mi Mi ‘ HN Hi FOR IRON AND is supported at each end by a frame or trestle, extending downward, and having wheels in| through which the its base to permit of travel upon two longi tudinal tracks laid upon the ground, so that the entire structure can move endwise upon the latter, and the load, which is suspended from a truck or trolly on the bridge, can be moved transversely across the bridge. 5. Rotary Bridge Cranes.—Which com bine a rotary with a rectilinear movement, and consist of a bridge having one end pivoted toa central pier or post, while the other or outer end travels ona circular over head track, or is supported by a gantry frame traveling upon a circular track upon the ground, the load being susp-nded from a truck or trolly traveling transversely across the bridge. 7 The above nomenclature will be adhered to in the follow ing descriptions of crane con struction HOISTING GEAR The most important factor in the eeonomy and convenience of a crane is the mechanism | by which the load is lifted and lowered, as |} it must necessarily come into action every time the crane is used, In all applications of power, from whatever source derived, it must be remembered that the gearing of a | machine can only modify the power applied } | ‘ . i Hi i Hi a mi \ | ‘ i 4. Gantries.—In which an overhead bridge | power is usually effected partly by reducing its velocity, and srepantionnbels increasing its force or “pull.” 2. By increasing the velocity and proportionately decreasing the intensity of the power transmitted. Unde no circumstances, unless the motive force is increased, can power be gained except by a sacrifice in speed, or can speed be increased except by a sacrifice in power. If either on hoth must be increased without diminishing the other, it can only be accomplished by supplying more motive power. The function of gearing, then, is to change the force or direction of the power applied. If itis well designed and constructed, this may be done with only a small from friction, while if badly made, the gearing may absorb much power in wasteful friction of its moving parts. In machinery for hoisting, the ‘* pur chase” or conversion of velocity into lifting loss ae A ch z Ht a = ot 4 ° } 1 i M4 WM Vi iW i f 8 i ‘ Wi 7 A e i a i MI ne Ht Mi HH i i} i STEEL, a multi- ropes or chains of the tackle load is suspended, and which | plication of the partly by gearing within the machine, latter thus becomes an important feature in crane work. The gearnng ordinarily used for this purpose consists either of spur wheels and pinions or of worm-wheels and worms, or both combined, smooth ness and economy of power of the depend largely upon the manner in which the gearing is made. A second feature of prime the hoisting gear of a crane is sustaining the load and guarding against its ‘running down” when the application of the motive power is discontinued This has heretofore machine having spur gearing, pawl of which has to be entire to permit lowering to occur r bya and the machine importance in the mode of been accomplished, in by a rachet-wheel, th ly disenvayed brake which, when on, prevents all motion of the machine, and which requires to be held o thrown off both in hoisting and loweriny In machines having worm gearing, the e1 is attained by a construction of their worm wheels such that the friction between th worm and the wheel is sufficient to prevent the backward rotation of the worm unde: the pressure of the teeth of the worm-whe« caused by the load, the resistance thus gen erated sufficing to prevent the running down of the load The worm-wheel system is usually safe against accidents, but is not economical ¢f proportioned, power if the worm gears are as above explained, to hold the load sus pended without running backward when the application of power ceases, as is usually the case. The spur-wheel system, on the other hand, is a constant and inevitable source of great danger both to the load and to the operator. With the least carelessness in lowering, the load begins to descend with great velocity, and the mechanism is dr.ven backward with ecrresponding speed and violence. If not checked the load then prac tically falls as if unsupported. If too sud denly checked, violent, strain is thrown upon the entire frame of the crane and on its gear ing, which latter is thus liable to damage, and even to ‘‘ stripping” or fracture, in which event the load falls. Where spur- geared cranes are operated by hand this ‘running down” of the load involves a re ver-ing or ‘‘ flying back” of the cranks, which then frequently strike the men before they can escape beyond their reach. Acci dents of this kind, resulting in injury to limbs, and even to life, are constantly hap pening with common cranes, and are re ported almost daily in the newspapers. It is possible, however, so to proportion worm gearing as to place it almost, if not wholly, upon a parity with spur gearing in ‘regard to economy of power transmitted, provision | changes of speed in hoisting and lowering, | permits a and, by the use of cut worm-wheels driven by turned worms or pinions (the teeth of the wheel being formed by means of a chasing hob or cutter), so to construct worm gearing that it becomes the best and most convenient form of gearing for use in crane mechanism It is found that gearing thus made will not automatically support the load, and that the latter, if left suspended, willdrive the worm gearing backward, but in this case the de scent of the load is quite slow, and no per- ceptible acceleration takes place, so that the worm gears thus act as a governor to con trol the load. By the application of a small brake to the worm-shaft this tendency is counteracted, and, by connecting this brake with the levers which control the motions of the mechanism, the brake is easily made automatic, and thus securely holds the load whenever the crane mechanism is at rest. In all cranes, except those of small size, should be made for one or more so that the speed may be varied according to the load and the nature of the work to be done. Cranes operated by power may be so constructed that the maximum load can be lifted at the quickest speed ; but they are usually so proportioned that this can be done only at a slow speed. By this plan much vconomy of gearing, space and effected, and the practical efficiency of the crane for all ordinary uses is not impaired (he most perfect construction is one that change of speeds to be mace cost 18 | whether the hoisting gear is in motion or at | tions to the | friction. j}and the rest, and which sustains the load automat ically while a change of speed is being made The hoisting gear of a crane should there fore attain the following results, viz.: 1 Such changes in direction and velocity of the power applied as will give the desired mo load. 2. The accomplishment of this with a minimum loss of power through 5. The safety both of the operator load, under all conditions, to insure which the load must be always self-sustained and incapable of ‘‘ running down.” 4. Ca | pacity for changes of speed and for con | venient transition from one of these to another at will, whether the gearing is in motion or at rest, and for the automatic sup port of the load during the act of changing speeds lo be continued.) a At the Otis Lron and Steel Works, in Cleve land, there is a great deal to attract the ittention of the mechanical engineer. Dur were ing the visit of the American Society of Mechanical Engineers, several of these things many comments made on castings and steel Among others was a gear-wheel, plates and a roll. The ro.ls are bottom, and the metal is fed strony rotary rh the center of the made on end, and in each case are one-third the hight of the solid casting [he molds are all made in il flasks, and the metal itself used in a very fluid state.

Without following Col. Fox Rivers’s vivid description, which will shortly be issued to the public, it is interesting to trace the growth of these door-fastenings and treas- ure-keepers. The inventive Chinese had al- most constructed a Bramah lock when Egypt herself was young, and the keys found in | our tumuli and tombs show how much ip- these supposed safeguards in allages. The rude savage was contented, in all probability, with a combination of knots, and, indeed, Captain Galton, in his ‘‘Art of Travel,” laments the want of some form of knot which would, while holding tight the stores, show whether they had been tampered with or not—thus asking for a Chubb’s detector lock of sinew or string in the bush or the desert; but such a series of knots does ex- ist, and possibly a native guide or attendant would fail to untie the famous knot which so puzzles ingenious monkeys. Alexander found it easier to cut than untie the famous Gor- dian knot, and many primitive locks in use, even in the British Isles, depend on a com- bination of string and wood, which suffice to keep out cattle, if not burglars. guard against the latter that modern in- genuity has been so freely expended, and it would appear really as if the latest Yale lock was only a modification of the well-known Egyptian model of some thousand years ago, and there are in existence examples of locks on the Egyptian model which have survived, and are found to answer their purpose even at the present time, and it has been sug- gested that, with a slight modification, this could be used with advantage to “‘ lock” pic- tures on gallery walls, so that they could be removed, in case of fire, easily and rapidly. This lock was obviously invented to secure a bar of some size, and has since been used on a much smaller scale. Sozae of the earliest and most perfect specimens of locks which have come down to us are padlocks and fetter locks, some, ap- varently, only adapted to fasten the girdle of a lady, while others are ponderous enough for the heaviest chest. pcm of these are in every museum of importance They have been found in London, in Colchester, and in Silchester, as well as in many other Roman sites in England. Some of these might be copied with advantage by our metal workers at a time when cheapness of production is not the rule, as at Willenhall, where good locks can be made and sold at a profit at a few half-pence a dozen. When some of the examples shown by Colonel Fox | boiler might be It is to| genuity was expended in the construction of | '7°4; scribed by the Marquis of Worcester in his ‘Century of Inventions.” He | little key, not weighing more than a shilling which shall be capable and strong enough to bo t and unbolt ‘‘ round about a an hundred bolts, through fifty staples, two in each, with a direct contrary motion, and as many more from both sides and ends, and at the same time shall fasten it to the place beyond man’s natural strength to take it away. = He also describes a curious es | cutcheon, and it was for the invention of a ‘secret apparatus” of this kind that the their first Marshall, shortly after the their Transactions, in describes a great chest, 1784. That there were warded keys and locks from Roman times is indisputable, and they were excellently made by the early English metal workers. Noone suspected their weak ness until a century ago, and then their un reliability was proved by the easiness with which they were picked by the simplest nov- ice in housebreaking. In vain were back springs invented and French tumbler locks introduced. A simple piece of twisted steel sufficed to open them all. The ponderous wooden and iron contrivances which had been trusted as locks should be trusted if they are reliable, were found to be of little worth. The tumbler locks of Barron and of Bramah, patented as far back as 1778 and respectively, head a long list of invent ors of many tumbler and wheel locks. There have been locks with master keys invented, and changeat le key-locks invented for doors of safes and other receptacles for valuables. These hardly came within the cognizance of the Society of Antiquaries. They belong | rather to the domain of the mechanical engi neer. Many of the latter are nearly perfect specimens of simplicity and security, with keys which, if not so light asthose mentioned by the Marquis of Worcester, are at least sufficiently portable to be carried in the waist-coat pocket. There are specimens of many of these ancient locks in South Ken- sington and in the British Museum, with keys remarkable for beauty of design as well as workmanship, showing, if another instance were needed, how well beauty can be combined with utility. - I Hot and Cold Water for Testing Boilers. The following is the very interesting dis cussion that took place at the recent Master Mechanics’ meeting at Chicago, on the rela tive value of cold water or hot water for testing boilers : Mr. H.N. Sprague, of E. K. Porter & Co said: For several years I had been testing boilers with hot water, and in my ignorance I thought [ was doing the best thing I could ; but the question has has been raised once or twice with me lately by parties as to whether hot water was better than cold water, or as good as it, and I wished to see whether there was not some one, perhaps, more scientific than I am, who « oul 1 tell me My idea has always been that the way to test anything was under the conditions in which it was expected to work, and that a boiler expanded by hot water would receive the strains under similar conditions to those of practice, and possibly the construction of the such that it was weaker un der expansion than what it was when cold, j and, if so, that was certainly the proper way | to test it. Rivers come to be more generally known, it | is possible that there may be some princ iple | which even our acute lock-makers have failed to discover. It is well known that Bramah believed his famous lock to be un pickable, because he could not pick it him self, and this has been the case with other jis not the best for having I can pressure But so far as i can judge, no scientific knowledge of the matter, not see any reason why hot-water testing boilers: but I | would like to know if anybody has an oppo | site opinion. Townsen, of the Canadian Pa I would ask the gentleman Mr. N. W. cific Railway : inventors, though perhaps the triumph of | whether he is speaking of applying the hot Hobbes, in 1851, in proving that the cham- | water to old boilers or to new boilers ¢ pion lock was pickable, excited the most at tention ; smali keys, imitate the lock which required | a species of sickle to open it, for this key has to be carried over the shoulder, like the Egyptian keys which are mentioned in Isaiah, and figured in the great temple of Karnac, in use at the present day. keys could only be used to move a bolt on a large gate, and when, as in many modern instances, the bar was hung in an iron frame and suspended in the center by a chain, a| smaller key was required to open it, and thus gave rise to those ring keys described by Tacitus, and which answered the purpose of a signet ring as wellas a key. Many of the wards of these Roman keys ere so much | like the ordinary in common use a generation ago as to sug- gest a doubt as to their antiquity. The curious implements found in Anglo-Saxon graves, and which are supposed to be keys, from their being fastened together by a ring and slung at the girdle, are, as a rule, but rude pieces of bronze, without a pretense to the formation of a ward, and in this particu | lar only do they resemble the keys of the Yale locks of to-day. Among the locks which seem to have been most popular, and which are indeed the puzzle locks.” They are found in the ia of a bird, as in India. They are hidden in the interlaced bolt-and-belt ornamentation of an Elizabethan linen-ches , or in the form of a ‘letter’ lock, and then they are independ ent of a key. The former depend on a secret the latter, on a certain combination of words, which re quire to be remembered accurately by the | person using the lock, or it becomes useless |to him. Some of the more modern letter locks are very ingenious—in fact, more in genious than secure. A couple of centuries ago they were far more popular than they are now, and in the time of our grand- fathers, and even later, these secret springs and hidden mechanism were freely used by the novelists of the Mrs. Radcliffe school. tlat or French latch-key | | I suppose, These sickle-like | They could only be | Brass Goods. | used to raise the rudest form of latch. but we shall not, in our desire for | for testing new boile rs only, As a rule, I have occasion but Ll can hardly in this respect between a Mr. Sprague : see the difference new and an old one. I might say, that I understand th: is to test with cold-water pressure is what raised the question of the comparative advantages of the two methods I cannot conceive any reason why hot water is not better than cold, and I want to find out if anybody can Mr. Townsen: I have tested boilers eold in the Woodwich Arsenal for the English Government, and on my own road [ test them warm. I don’t ge steam at all, and very seldom use I fll my boilers every year with water, and make a light fire in the furnace, and by the expan sion that way I get any required pressures If [| have any doubt, | go inside the boiler and examine it, and find out its condition as well as I possibly can, and then test the by the expansion of the wate I don’t gen erate any steam at all Mr. Richard Williams, of the Patent Shaft and Axle Co., Limited, Wednesbury, Eng land, said We works in connection with our establishment It isan important part of our business to test them No doubt, if it were practicable. in a reasonable way, to apply tire for the testin it might be advantageous but the pract with us is simply one of testing the sound ness of the boile: prompt and we therefore consider that the hvdrau! pressure is all that is necessary for the test further, (rovernment practice and that, herate an a pump, » boiler have a very large boiler und economically ing of a new boiles We tind that result of very many vears’ practice, if a boiler has stood successfully the hvdraul test, which is considerably ovs nV possil steam-pressure test, it never ifterwa is found imperfect in use as a boiler It economical, and promptly Our water Mr. Sprague It is cheap with hot water.
