New York. September, 1915. RAILWAY AND LOCOMOTIVE ENGINEERING. 31S Heavy Hydraulic Shear for the United States Government The accompanying illustrations showfront and side views of Wm. H. Woodsshear, as built for the United States Gov-ernment, for shearing heavy vanadiumsteel plates lj^-inch in thickness. The shearis designed with a 26-inch throat and hasa capacity of 200 tons to shear the plateswhen working from a hydraulic accumu-lator pressure of 1,500 pounds to thesquare inch. It will be noticed from theillustrations that the shear blades arereversible and the shear is prepared foruse so that the shear blades can be re-moved and substituted with attachments,with punches and dies for punching heavy.

It is well to state that nearly thewhole of the machine is made from caststeel on account of the heavy pressurewhich is required for shearing the plates,the rams being made of air furnace castiron. The glands of steel, bronze linedand capped. It is fitted up so that thedirect shear movement works through arectangler guide having extended surfacefor the resistance in cutting heavyplates. The return stroke is made by thedirect pull back cylinder on the top of themain cylinder and directly connected withthe guide carrying the shear blades. Itis conveniently arranged with a bronzebalanced type of valve of Mr. Woods latest type and is vci> convenient anddirect tor handling and working of themachine, either by hand of by toot. Onaccount of the excessive pressure at whichthe shear is worked great care has beentaken in the materials used in its con-
