Abstract

1,183,422. Pile drivers. DELMAG-VERWALTUNGS G.m.b.H., [trading as DELMAG MASCHINEN FABRIK REINHOLD DORNFELD]. 11 March, 1968 [15 March, 1967], No. 11731/68. Heading B3H. [Also in Division F2] A diesel driver with a free-falling piston 12 and a striker 13 is provided with a cushioning ring between a collar 13e on the striker and the cylinder 11. The ring is preferably formed of a metal ring 21 with spaced rubber or like resilient material segments 22 fixed to the ring by moulding in holes 21a in the ring. The metal ring has its upper surface recessed 21c between the holes and it is bolted to the cylinder. The segments define recesses 23 on the lower surface of the ring. Alternatively, the rubber ring may be continuous with recesses formed therein or the cushioning ring may be segmented and the segments fixed at spaced intervals to the cylinder. The spaces or recesses on the face of the ring adjacent the cylinder reduce the heat transmitted from the cylinder to the rubber ring and also serve as air cooling passages.
