The distributing valve isfastened to the side of the cylinder bymeans of a clamp which passes aroundthe bushing. This machine convenientlylocated will save considerable handlingof material. Ira A.

SHEARING MACHINE ON THE B. C. R. & N. with one stroke of piston, when a pres-sure of 90 lbs. per sq. in. is used in thecylinder, which is 24 ins. in diameter and12-in. stroke and is fitted with a pack-ing leather for upward pressure and onefor downward pressure. The power iscompressed air. The lower end of the blade for shear-ing rivet heads is made with one sideslightly longer than the other for thepurpose of distributing the work requiredto cut the rivets through more of thepiston travel than would be the case witha straight cutting edge on the blade. Theair distributing valve, which is notshown on the drawing, is made from amain valve bushing and slide valve froma gY>-m. Westinghouse air pump. Theends of the bushing are closed by meansof plates held on by rods extending fromone to the other. Into the center of oneof these plates the bonnet from an oldi-in. globe valve is screwe
