Cramps.-In fluidpressure - actuated jacks, applicable for use as clamps, pistons 17, 19 are disposed on opposite sides of a partition 14 in the cylinder 1C and are connected bv a rod 18. The skirt 16 of the piston 17 takes over a hollow extension 15 of the partition 14, and a spring 29 is placed between the head of this extension and the piston 19. By means of a pump A this is forced from below the partition 14 to its upper side to raise the piston 17. Lowering of the piston is effected by the spring 29 when a valve (not shown) is opened to allow fluid to pass from the upper to the lower side of the partition. A safety valve 32<1> is provided. The lower end of the cylinder is closed by a detachable plate 11 which can be removed to permit the connection of a rod 36, Fig. 3, with the piston 19 when the apparatus is to be used for clamping overlying plates prior to riveting. Specifications 144,351 and 155,206 are referred to.

Synchronized lifting and lowering apparatus

A synchronous lifting or lowering system with hydraulic cylinders controlled by parallel- connected lift valves having two fluid passages. Hydraulic fluid for extending or retracting the actuators is delivered by a hydraulic supply system alternating between the two passages. Each time the supply circuit alternates passages, a fixed volume of hydraulic fluid is transferred during lifting or received during lowering by the respective lift or lowering valves to or from the cylinders causing the rods to lift or lower a proportionate amount. All of the rods extend during advancement or retract during lowering by approximately the same increment each time the supply circuit alternates passages. Because the rods all extend or retract the same increment each cycle, the load is lifted or lowered evenly and the need for height sensors or transducers is eliminated.
