Abstract

667,422. Percussive tools. BRITISH JEFFREY-DIAMOND, Ltd., PEARSON, D., and YARMAK, J. June 27, 1950 [Oct. 27,1949], No. 27603/49. Class 124. [Also in Group XXIX] A vibrator mounted on a machine structure comprises multiple movable bodies arranged to strike in two opposite directions on the machine structure under the influence of rams operated by a motor driven hydraulic pump and a hydraulic fluid. As shown, a striker 17, Fig. 6, moved by a ram 12 by hydraulic pressure from an inlet 44 and passage 58 strikes a blow on a plate 37 and moves a valve rod 5 to open a port 64 which allows pressure fluid to act on a ram 11 and cause a striker 18 to strike a blow on plate 37, Fig. 7. Striker 18 moves a valve rod 4 allowing fluid pressure to operate on a ram 13 causing striker 17 to strike a blow on plate 38, Fig. 4, and move rod 5 to open a port 49 and cause pressure fluid to operate on ram 10 and hence striker 18 to strike a blow on plate 38. The unit illustrated may be mounted on a machine structure of which the plates 37 and 38 form a part and which may have facings of rubber.
