This promotes easier machining with better results—eliminating rejec- tions due to hard spots or other physical structural weaknesses. The micrographs (in the circles above) tell why. The upper circle shows a micro- graph of Superior Charcoal Pig Iron. Notice that the graphitic flakes are very small and nodular (knot or hook-shaped) in form. This structure provides greater strength. In ordinary pig iron (micrograph in lower circle) these flakes are coarse, large and straight, 13 contributing decided weak spots. In Superior Charcoal Pig Iron both combined carbon and gra- phitic carbon are more firmly en- meshed, more evenly distributed and properly balanced. This imparts to the structure of cast- ings better continuity of these elements, therefore greater transverse and tensile strength. Such definite assurance of better quality and less rejections and losses far out-balances the slight additional cost in the cupola mix- ture (5c to 6c per 100 pounds for 20% Charcoal mixture). Many other desirable qualities peculiar to Charcoal Iron Cast- ings may prove advantageous to your product.

They cut 10 D.P., 4 to 1 ratio gears up to 4/2 in. pitch diameter and 1 to 1 ratio gears up to 34 in. diameter. A full set of change gears and segments is furnished with the machines for cutting any gears within their capacity. The 3-in. Generators are built for both roughing and finishing operations. They are easily set up and changed from one operation to the other. High tool or cutter speeds are maintained without sacri- ficing the quality of gears produced. An automatic stop eliminates the possibility of recutting a tooth and allows one operator to handle several machines. Cutting times on these generators will be given on receipt of blueprints.

To be sure, the mighty frame of structural steel is firmly rooted in solid stone... yet, because they are extending man’s hori- zons, both plane and skyscraper are kin. Steel reaches into the future as no other fire-resistive material does or can... is ready with its full strength and adapta- bility, its great security and economy, for all tomorrow’s wants. Meanwhile there is pressing need for steel construction in smaller buildings—in homes, apartment and mercantile houses, schools, indus- trial plants and small bridges. Here, also, steel saves building time and material—provides more floor space with less weight, less bulk—secures quicker returns on investments and longer usefulness. Before building anything find out what steel can do for you. The Institute serves as a clearing house for technical and eco- nomic information on structural steel, and offers full and free co-operation in the use of such data to architects, engineers and all others interested. The co-operative non-profit service organization of the structural steel industry of North America. Through its extensive test and research program, the Institute aims to establish the full facts regarding steel in relation to every type of construction.

The testimony is overwhelming. For instance, one of the world’s largest manufacturers, using hundreds of FIRTHITE TOOLS—many with MECHANIGRIPT tips—-has many records of which the following are typical: Application No. 1—Turning, boring and facing cast iron Induction Regulator—intermittent cut. With high speed steel, one casting cost $14.67 With FIRTHITE, one casting cost 6.69 Saving $ 7.98 Application No. 2—Boring and facing A. C. Motor Frames, cast iron. With high speed steel, one casting cost $11.83 With FIRTHITE, one casting cost 7.95 Saving $ 3.88 Another concern saves $83.18 per roll, turning and facing sugar mill rolls, 84” long by 38” in diameter, with FIRTHITE TOOLS. A manufacturer of oil well machinery, using FIRTHITE for turning pump plungers of chrome nickel steel (Brinell Hardness 450), reduces the total elapsed time from 5 hours and 50 minutes to 2 hours and 30 minutes.

Equally important, they must possess just the right combination of those more or less indefinite properties for which no fixed standards exist. The obtaining of such alloy steels is a matter in which you must depend to a great extent upon the ability and reputation of the steel- maker. During the many years that Bethlehem has been supplying large tonnages of alloy steels for motor vehicles and for other purposes, Bethlehem Metallurgists have made a thor- ough study of the effect, from the consumer’s point of view, of the variations in those pro- cesses not subject to definite scientific con- trol. As a result of the knowledge gained of the users’ problems, this Company’s metallur- gists have been able to so organize the metal- lurgical control in the Bethlehem Alloy Steel Plant that all operations—those where human judgment predominates as well as those sub- ject to definite scientific control—are gov- erned in a way to best meet the customer’s needs. Alloy steel users are coming to Bethlehem for alloy steels in large and constantly in- creasing tonnages. BETHLEHEM STEEL COMPANY General Offices: Bethlehem, Pa.

We would like the opportunity of studying with you the various steps now necessary in your manufacturing processes, and recommending for your consideration any betterments or improvements that Palmer-Bee Conveyors might present. Palmer-Bee recommendations are not long range, hit- or-miss calculations but are based on a carefully studied, thoughtful analysis of both your plant and product requirements in consultation with your own engineers and based upon your own manufacturing data. Twenty-five years of conveyor experience have taught us the pitf: ills which beset the unw ary and the unskilled in this business and we know what to do, as we know also the equally vital things that should not be done. We have just prepared a book of modern conveyor information showing photographed installations which will give you some idea of the extent of our coverage of the conveyor field, and may present to you some ideas applicable to your own business. We will be glad to send this to any executive who may be interested and will welcome your inquiries for information of any kind relating to mechanical conveyors. ——h-~ es Pius You HAND CRANKING YOUR PLANT ?

EVERY DIRECTION OPEN STEEL FLOOR FLOORING ARMORING i The Continuous feature, exclusively distinctive of Irving Flooring and Armoring, is simply the latest in a progressive series of steps toward improvement made by Irvimg engineers. Although it was developed with a view to betterment, rather than to cheapening, Irving facilities and production are such that you can enjoy the outstanding advantages of Continuous Flooring and Armoring at no extra cost over what you will be required to pay for an obsolete, make-shift arrange- ment of separate panels, or bars and rods. When you can buy more, without paying more, in Irving Continuous, what reason remains for using inadequate substitutes? Have you Bulletins G-7 and K-7? IRVING IRON WORKS CO. Long Island City, N.

NOT GUESSWORK form the basis of successful management HE man who manages the fac- tory has a production sched- ule to meet. He must also maintain a high standard of quality, and at the same time seek to reduce costs so that his product may find wider markets and greater sales. Such a man wants FACTS on which to base decisions; there is no room for guess-work, impressions, traditions, haphazard methods. His success de- pends upon knowledge and control. Bristol’s instruments give him this knowledge and control of the proc- esses where temperature is a factor. Such control can be adapted to virtu- ally all processes involving the appli- cation of heat—any fuels, in any com- binations—any desired temperature range up to 3000° F. Bristol’s Engineering Service is at your disposal to aid in working out Control problems. There’s no obliga- tion.

We are proud to be in a position to qualify to every demand of the advertiser, as our records are regularly examined by the A. B. C. Our last audit report is available and open for in- spection and is full of facts that the advertiser should know in the placing of his appropriations. THE IRON AGE 239 West 39th St., New York City July 3, 1930 THE IRON AGE 39 wy Shay Mechanical Man It is unnecessary for the Operator to exercise any particular care in shutting off the current when the bucket is fully closed as an auto- matic electric feature permits the motor to stall at a predetermined safe value of torque, sufficient to maintain the closed position without causing undue strain on the mechan- ism. This eliminates the necessity of a troublesome mechanical slip friction clutch. es When the bucket is fully closed and the power is shut off the automatic brake sets and the bucket cannot be opened until the motor is re- versed. A return device on the con- troller causes the handle to return to the off position when released by the Operator “Electrically Operated And Controlled’’ When an obstruction is encountered while closing or opening, there is no harm done to the mechanism, as the same automatic feature acts to protect the bucket when fully opened or closed. As the bucket is electrically operated and con- trolled, there is no readjustment needed in the field. Briefly the operating mechanism consists of the electric motor directly connected to a drum by a worm gear drive, which winds or unwinds the cable opening or closing the bucket. It is as near fool-proof as possible. E bk i E You Will Want To Know . HOW IT WORKS J Write For Bulletin ClamshelljAnd Electric Buckets Overhead Electric Traveling Cranes ERIE STEEL CONSTRUCTION CO.

Dee i ee a | 40 THE IRON AGE July 3, 1930 A RECIPE for duplication minus complication Mass production with its rapid-fire duplication has its me- chanical complexities. There’s a two-sided problem forever con- casein the production man — how can | lower my costs without sacrificing quality? To these men in particular the Natco C1OH drilling machine, equipped with 42 New Departure Ball Bearings, has a special appeal. All of its 16 adjustable spindles are rigidly supported against radial and thrust loads by New Departures. Drills start cutting as soon as pressure is applied, since no appreciable looseness must be taken up in these bearings. Because of them, drills hold their edges longer — bearing wear and upkeep are practically eliminated. You can pick the speed that best meets your conditions with full assurance that New Departures are more than equal to the task. Thrust is carried with free-rolling smoothness as are all other loads — by balls that are large and perfect, which roll in grooves, deep and mirror-smooth. The New Departure .Mfg. Co..
