Stutz, of Pittsburgh, Pa., presented a paper on coal washing in general, and upon the ma- chinery devised by him in particular. He discusses the general principles underlying the construction of that class of machinery, and points out the great advantages derived by a preparation of coal. These are striking in the case of fuel to be used in the manu- facture of iron—notably in those processes where, as in the blast furnace, the metal has an opportunity to absorb the impurities of the coal orcoke. Aside from its value in reducing the sulphur in the fuel, the per- centage of ash is brought down to a low limit, so that, even with our best coal, it is a question well worth careful consideration whether the eutlay for preparation is not fully covered by greater economy in its sub- sequent use. Mr. Stutz in his paper de- scribes the most recent forms of the ma- chines which have been employed by him for the washing of bituminous coal and slack.

This may originate partly |from the pressure to utilize the canals to their greatest possible extent, and partly |from the apparent failure of the Belgian | towing system, which has been thought of as a possible solution of the entire difficulty heretofore experienced. Be this as it may, we are informed by a well-known builder of engines that there are now under way 50 or 60 steam propellers at Fishkill, Tonawanda, Buffalo and other points convenient to the canals, and that there is a very general inquiry among the boatmen, who want a substitute for horses. There is now no question about the practicability of using steam, nor respecting its commercial advan- tages. State Engineer Seymour, who appeared last week before the Assembly Canal Committee, stated that the time con- sumed by a cable boat in passing from Buf- falo to Albany is two days and four hours, while the time for a horse boat is about 10 ZL WANE? - SS ~ ~- y CLlhy Be — af “ ( SRSSEIZ w / 7 Lh Mz yy SS — SS 9 SSS RSS v SS * ZY, SS BY ZZARS ce SSS Ss 4 PR — ‘awk rT aa 3 S KLP 7 SE, e ~~) SAS i a ‘ be THE STUTZ COAL JIGGER.

The means | which he has adopted to accomplish this end are quite ingenious, as will be seen by refer- ence to the accompanying drawings. It should be stated, however, that for ordinary purposes Mr, Stutz prefers his ordinary type. It is chiefly adapted for the working of poor slack coal. Briefly, the operation of the machine is as follows: The rotary movement of the cam shaft, C, is converted into an ascending and descending movement of the piston P, the | upward stroke being quick, while the return is slow and gradual. By this means the impure coal, which is fed from the hopper J upon the sieve S, is suspended in the water and is then gradually allowed to fall init. The coal being lighter, is floated off over the bridge m, while the slate and pesties gathering on the bottom is discharged through the valve H, and falls into the| reservoir N, from which it can be allowed to drop by drawing open the valve o by means of the lever 1. The piston P, it will be Roticed, occupies only a portion of the space below the sieve, the remainder being reserved for the purpose of obtaiving a channel, a, through which the fine coal and slack drawn through the sieve by the back suction can be | charged inte the lower part of the box A. order to facilitate the gathering of the negative pole of the battery. tive pole of which is connected to the plati- num stylus through a sensitive selenium cell, the circuit being completed also through the zine plate and the galvanometer. Now, if the selenium cell be exposed to a strong light, or, in other words, if a beam of light be focussed on it, and the variable resistance be so adjusted that the opposing currents in | the two battery circuits exactly neautralize | each other, no current will flow from the| stylus to the plate across the iodized paper, | and hence no stain of liberated iodine will mark the paper if the stylus be drawn across it. But if the light be shaded off the se!en- ium, the resistance of the latter will in-| crease, and the current from the first bat- tery will, therefore, predominate, so as to} cause a flow of electricity down the stylus. When the stylus is drawn across the paper it leaves its trace as a brown mark of liber- ated iodine; and this trace is strong or faint, according as the current is strong or feeble—that is to say, in proportion as the light is less or more intense. The galvano- meter serves to indicate when the balance of currents is exact; and the connecting wires which correspond to the telegraph line between the two stations, where the From the very nature of the settings, there can be no electrical reasons for explosions.

A complete steamer costs to build about $6000 cash, of which $2600 is for the engine, steering gear ane whatever else the ship carpenter is unable to supply. On the mortgage plan the cost to boatmen would be about $7000 at 6 per cent. interest, payable in installments extending over two or three years. We learn that an effort is making to form a syndicate for the construction of canal steamers on the mortgage principle, and confidence is expressed that, if this plan can be carried into execution, 500 steam canal boats could be put afloat within a year, or as fast as it is possible to build the engines. sesceesiehaniecitadeonidlcatiiatansamdaie The Pittsburgh Bessemer Steel Company, Limited, started their new works at Home stead on Saturday, waking the first ingot at noon. The converting and blooming ma chinery worked very satisfactorily, and will be run steadily from this date. A slight accident occurred with one of the ladles, which, in being lifted, was tilted backward, pouring a smal) quantity of molten steel into the pit. In springing to get out of danger, Mr. Chas. L.

This is one of the best side hinges in use; it works more truly and is less liable to get ut of order than almost any other. Many founders do not like side hinges, but prefer to use corner hinges on all flasks. Figs. 38 and 39 represent a very plain, cheap corner hinge, which is used altogether in some foundries. It is made from 6 to 7 inches long and 114 inches wide. The piece, Fig. 38, is put on the cope and that of Fig. 39 on the drar.

Two flask pins are always put on the side opposite the hinges to serve as guide pins and prevent the cope from shuck- ing on the hinges and drag when the mold is closed. Inthe Eastern stove foun- dries almost all the large flasks are hinged, so that a molder can roll off or close any ordinary flask without assistance from his partner, and two molders can generally handle the largest flask in the foundry. A great deal of time is thus saved, and the molder is enabled to put up more work, for he loses no time waiting for a hand or lend- ing his partner one. In many of the Western stove foundries no hinges at all are used on the flasks, and a molder cannot lift off or clcse a single flask of anv size without the assistance of his partner. This giving and waiting for a hand takes up a great deal of time, and a molder who works with hinged flasks can always put up two or threo more a day than one who works with flasks that are not hinged. The fact that no hinges are employed in many of the Western stove foundries, where the long-handled flasks are used, is owing partly to the prejudices of the molders against them, and partly to the fact that pattern fitters and follow-boarders do not understand how to draft and follow board the patterns so that they will work right with hinged flasks. If these prejudices and difficulties could be overcome, and a good flask hinge adopted and used in all stove foundries, the molders could do better work and more of it, and would earn more money with less labor. — el = Machine Gun Trials in England, JUSTICE cox, Jr, CHARLES K, BARNS, JUSTICE COX, JR. & CO., AGENTS FOR Chickies, St. Charles, Montgomery : and Keystone ‘Foundry & Forge Pig Iron.

The guns thus tried have been of two classes—the ‘‘ light,” for ship and boat service, and the ‘‘heavy,” for service in the field. There were originally three light guns, the two- barreled Gardner, weighing 100 pounds ; the five-barreled Nordenfeldt, weighing 143 pounds ; and the six-barreled Gatling, weighing 200 pounds’ The heavy gun
