Abstract
313,516. Haage, K., and Pfl³ger, A. June 13, 1928, [Convention date]. Percussive hand tools.- An internal - combustion hand-guided ramming or like tool has a free piston e working inside a cylinder a with a valve s similar to that described in Specification 293,228 and exhaust ports u. The valve s being open at starting and the piston raised and depressed by a handle r, the valve s is then closed by hand and the charge fired by means of a suitable hand lever. The cylinder rises, compressing the spring p until the exhaust ports are uncovered, when the relief of pressure allows the piston to rise to the top of the cylinder under spring pressure, the guide rod m also rising until the foot n strikes the cylinder end. The whole tool then falls and delivers a blow, and the piston descends further to draw in a new charge. A strong cushioning spring q is provided. A tubular dust excluder may be attached to the foot n. In a modified tool for use in pile driving the guide rod m is without the foot n and is fixed to the top of the pile.
