BETHALON, a new steel devel- oped and manufactured by Bethlehem Steel Company, is rust-proof; yet it machines as easily as ordinary screw stock, known as the most easily machined of steels. The way BETHALON goes through the automatic screw machine without changing feed, speed, or depth of cut, is a revelation to men who have ex- perienced the difficulties that ordina- rily attend the machining of non- rusting steels. Even under the ulti- mate tests of machinability—drilling, threading and boring — you would never recognize BETHALON as a rust-proof steel, from the way it machines. Because of its combination of rust STEEL resistance and easy machinability, BETHALON opens a great, new field for non-rusting steel. It possesses, in addi- tion, a very desirable combination of physical properties that make it avail- able for a wide variety of uses. Perhaps the use of BETHALON would in- erease the economy or serviceability of your product. Bethlehem metal- lurgists will gladly give you complete information.

New, Improved Duplex Air Compressors Ingersoll-Rand duplex compress- ors— Types “XCB", “XRB”, and “XRE”—are now offered in complete new designs that offer the user even greater values than the earliest models of these units that have for many years borne a reputation second to none. By taking advantage of prog- ress in metallurgy and engineer- ing design, we have improved these units in numerous respects. Main bearings are larger and better proportioned. Frames are stronger and more rugged, to carry greater horse-power loads. INGERSOLL-RAND CO, « New design cylinders have greater valve areas to increase compression efficiency with lower power input. Cylinders are better jacketed and improved circula- tion of cooling water conserves power, helps lubrication, and prevents distortion. Cylinder heads are smaller and lighter. Moving parts are lighter but stronger. Regulating equipment is eficient and dependable. Two- stage units have the intercooler transversely across the frame, con- venient of access without ladders. As a result of these and vari- 11 Broadway ous other improvements, these compressors conform to the mod- ern demand for more efficient operating speeds and at the same time provide units that are highly compact, easy to install and easy to inspect and to service. Types “XCB” and “XRB” are belt driven. Type “XRE” is direct-connected to a synchron- ous motor. Two-stage 100-pound units are available in capacities from 348 to 1,875 cu. ft. per min- ute piston displacement. Single- stage or high-pressure machines for all conditions.

As there are several teeth in mesh simultaneously and the size of the pinion is independent of the ratio, Hypoids have an added factor of strength especially at the higher ratios. Hypoids are generated by a new method. To ob- tain a correct tooth profile, the pinion is cut in an offset position similar to that in which it is to be mounted. These gears make possible designs not heretofore attainable and allow the improvement of many existing types of drives. Complete information on Hypoids is available.

From the crude stone implements of our cave ancestors down to the modern machine tool, the progress of mankind has been marked by improved tools and discoveries of better materials from which to make them. In our complex civilization the variety of tool re- quirements is infinite. The material that makes an excellent tool for one purpose may fail ut- terly on a different task. Tool steel research has progressed rapidly during the past few years. The high speed steel or the die steel that was the last word four or five years ago, is out-of-date today. ERIE STE BOSTON @ L PHILADELPHIA CHICAGC HARTFORD LOS ANGELES September 25, 1930 And now to challenge the supremacy of steel in the tool field, we have recently introduced to industry an entirely new type of alloy, FIRTHITE TUNGSTEN CARBIDE, a ma- terial of almost diamond hardness, approximat- ing the strength of steel and of extraordinary cutting capacity.

Peete) wae § PEEL THE IRON AGE September 25, 1930 CREATED CHE SEVSCRAPRED INEVITABLE ...THE ALL-STEEL CITY Topay’s breath-taking spires and spans of steel were “impossible” only a few brief years ago. Now walls of masonry are yielding to solid-section steel windows . . . new beauty comes in steel shapes and new skill devises their application . . . and on the horizon looms the amazing battle-deck floor. Eventually, cities will be all steel. Not only the skyscrapers and great bridges, but the- homes, schools, small apartment and mercan- tile houses, small factories and small bridges as well. For steel is the strongest, most versatile and fastest building material. Fabricated in mills, weather cannot delay its production—and rain, intense heat, or freezing does not impair its strength. It can be erected anywhere, at any time, as long as men can work—thus earlier returns on in- vested capital are insured, interest charges are saved. In cities, too, there is constant change, growth. Small structures give way to larger ones—must be altered, added to or replaced. Steel facilitates alteration and addition—and no other building material has such high salvage value, is so economically recovered, or is so readily marketed afterward. Before building anything find out what steel can do for you. The Institute serves as a clearing house for technical and economic information on structural steel, and offers full and free co-operation in the use of such data to architects, engineers and all others interested.

Each type was equal to the demands of its time, but its time passed, and prog- ress brought new demands. Disston was quick to meet—to anticipate—changing demands and changing conditions as their advertising shows and as is evi- denced by this latest development. But what of the future? Can it be said that this is the last word in saws, that no further improvement is possible? Hardly! And what is true of saws is true in other lines. It is unthinkable that we have reached the end of develop- ment. The 75th Anniversary Number of The Iron Age to be published November 20, 1930, is dedicated to the idea that the next few years will see still greater in- dustrial development and progress. It will sift from the events of the past facts which may have a bearing on the future. It will look back not merely to review the past but so that we may see ahead more clearly. It will be, in short, a ““projection”’ number. It will be an issue in which you can tell, to good advantage, the story of the part which your products have played in the past progress of the industry and will play in its future.

MAC-IT Hollow Safety Set Screws are used for holding down the plates through which all retaining screws are inserted for holding the many individual tool bits. Here, the MAC-ITS are subjected to the greatest strain of any of the screws used on the job. MAC-ITS are also used in parts of the machine’s construction, as indicated. “Where heavy duty is required of either a large or small screw used in places where interferences are not permissible, we always use MAC-ITS,” says a company executive. MAC-ITS will not break, mushroom at the point or become distorted with long use. Famous machine tool builders use them generously. September 25, 1930 STRONG CARLISLE | .......

CLEVELAND, OHIO September 25, 1930 THE IRON AGE 31 SUPERIOR STRONGER CASTINGS Closer grained structure with smaller, nodular shaped graphitic flakes provides greater transverse and tensile strength. ELIMINATION OF SHRINKAGE The use of Saperior Charcoal Pig Iron in foundry mixtures assures freedom from shrinkage—a most prevalent foundry trouble with ordinary castings. TOUGHER CASTINGS Firmly enmeshed, and properly balanced carbon structure imparts toughness to the castings, with more responsive working qual- ities. LESS SCRAP LOSS The fine quality of all Superior Charcoal Iron castings means fewer rejections, less scrap loss— money saved and satisfied cus- tomers.

Built to handle a certain few jobs well, its scope is still very limited. A change in the range of your operations handicaps its usefulness—possibly renders it obsolescent. The SUPER-SERVICE Production Drill is the latest word in upright drill presses. It is a specialized pro- duction tool—essentially a one speed, one feed machine . . but a quick transposition of a few gears gives a range of 16 speeds and 16 feeds.
