New machine to test brake linings designed by Bureau of Standards. Washington, D.C., March 16. A new machine, both in design and operations, has been installed at the National Bureau of Standards for the testing of brake linings. The machine permits the study of brake linings under conditions closely approaching those of actual sevice and yet which can be accurately controlled. It will make less difficult the complex job of revising the Federal Government's specification for auto brake linings. Wil. Holt of the Bureau is shown in the photograph, 31638

Fighting highway deaths, Wash. D.C. This photograph shows Richard S. Dill, a worker in the U.S. Bureau of Standards, tabulating the efficiency of various kinds of brake linings as the government attempts to determine the best for use on its vehicles. The automobile industry is watching these tests carefully as a possible indication of the kind of brake lining to use to reduce the number of deaths on highways, which numbered 33,980 in 1934, 10/4/35

Traffic paint undergoes rigid tests. Washington, D.C., April 16. At the U.S. Bureau of Standards, J.E. Keefauver of the Bureau has been running tests on the paint that is placed on safety zones and streets to determine which has the best wearing activity. The discs ? are painted with the traffic paint the chain-driven wheel of eraser rubber (to imitate an auto tire) slowly wears the paint away. The brushes are to keep the disc and tire clean. These tests were made at the requests of the traffic bureaus, 4161937

Two new tools were set in the New Britain-Gridley lathe, pictured above, to adapt it for the cutting of twenty-millimeter shell booster parts. The new parts are an eccentric spindle, which may be seen attached to a driving rod in the center of the machine, and a thread rolling attachment. In peacetime, the machine was used to turn out spur gears, worm wheels and commentator rings in steel and brass

Bending huge steel girders. Washington, D.C., Sept. 23. At the U.S. Bureau of Standards officials were witnessing the testing of rigid steel frame knees that are used in grade eliminations such as over-passes, under-passes, bridges, etc. This photo shows the girder or knee placed into the huge 600,000 lb. testing machine in preparation for the test. This welded rigid steel frame knee which was designed to withstand 50,000 pounds had a maximum load of 153,600 lbs placed on it before it buckled.

Conversion. Food machinery plant. This turret lathe was purchased second-hand from a nearby shoe factory to speed production on war subcontracts held by a New England plant which formerly turned out cube steak machinery. Edwin Becker is checking on a retooling job in progress which will eventually fit the new lathe to thread three-and-a-quarter-inch hexagonal nuts. Becker is checking the measurements of the tool hole in the turret with those of the specially-built tap which will do the threading. Cube Steak Machine Company, Boston, Massachusetts

Experts at Bureau of Standards study effect of corrosive soils on specimens of pipe. Washington, D.C., Aug. 8. Of interest to home builders the country over is the study being made by experts at the National Bureau of Standards of the effect of corrosive soils on pipes and protective materials. Samples of pipe which have been buried for four years in fifteen soils differing widely in their characteristics, are being tested. Included are several varieties of ferrous materials as well as copper, brass, and bronze. Soldered and brazed joints, protective materials, and pipe made of a composition of cement and asbestos are also represented. Walter Johnson, of the Bureau, is pictured removing graphitic corrosion from cast iron with an air-driven tool. The corrosion products are too hard to be removed with a brush or by chemical treatment, 8/8/38
