[Also in Divisions B5 and F1] A power-operated manual tool, such as a saw, polisher or scraper, comprises a pair of oppositely reciprocatory elements, one 14 including a tool holder 62 drive-connected thereto, and the other 12 having a weight 28 joined thereto of predetermined magnitude so that the combined masses of the other movable element and weight correspond to the combined masses of the one movable element and the tool to be used, so as thereby to afford vibration-free operation of the tool. The elements consist of pistons which are slidable in a sleeve 34 retained between end caps 32, 58 in a cylinder 10 which at one end is formed with a bore 26 slidably receiving the weight 28 on the rod of the piston 12, the rod extending through the end cap 32. The rod of the piston 14 extends through the other end cap 58 and, as described, carries an L-shaped member 62 to which is clamped a retainer 64 for a saw blade 22. A stem 70 extends from the end cap 58 and is slidable in a bore in the member 62 to prevent rotation thereof relative to the cylinder 10. The sleeve has a passage 72 which has branches 74, 76 in the end caps leading to grooves in the bores for the piston-rod and is connected by a control valve 20 and regulator to a source of hydraulic or pneumatic pressure. Further bores 40, 41, 42, 44, 46, 48, Fig. 2 (not shown), in the sleeve are connected by passages 52, 53 to exhaust. The branch passages 74, 76 co-operate with passages 78, 80, 82, 84 which are formed in the pistonrods and open to opposite sides of the piston. In operation, the fluid pressure causes the pistons to reciprocate in opposite directions, the weight 28 balancing the mass of the member 62 and saw.

Abstract: 596,759. Hydraulic shock absorbers. MONROE AUTO EQUIPMENT CO. Aug. 2, 1945, No. 19922. Convention date, Aug. 28, 1944. [Class 108 (iii)] A hydraulic shock absorber comprises a cylinder A in which is slidable a piston C having two sets 43, 44 of fluid passages, a single closure 48 for the two sets of passages which is normally closed but operable to resist the flow through both sets of passages, a second closure 70 for one of the two sets of passages, which is normally open but is adapted during piston travel in one direction to cut off the fluid supply through the latter set of passages. The piston C has spaced parallel sets of passages 43, 44, flow through which on the compression stroke is resisted by a spring loaded valve 48. An annular valve 70 normally free from the piston C and in slidable engagement with the walls of the cylinder A against the action of a spring 71, is engaged by the lower end face of the piston C under compressive displacements greater than normal and thereby closes the lower end of each passage 43. Damping for further compressive movement in this direction thus occurs through the passages 44 only. Flow through the piston C on the rebound stroke takes place through a third 'set of passages 45 and is resisted by a spring loaded valve 64. The passages 45 are in register with passages 60, 62 in a retaining member 50 for the spring 51 of the valve 48. The piston C and the member 50 are retained on a reduced portion 40 of the piston rod by a member 65 which also retains the spring of the valve 64. The spring 71 of the valve 70 is mounted on a member 17 which carries a seating for a spring loaded valve 25 which controls flow to a reserve chamber B on the compression stroke. Flow from B on the rebound stroke takes place through passages 19 and a spring loaded valve 28. The piston C has annular recesses 46, 47 at the upper ends of the passages 43, 44.
