Title: Improvements in hydraulic ram units
IPC: B66F9/04
Filed: 1961-08-11
Abstract: 953,133. Hydraulic rams; lifting machines. E. TEN KATE. Nov. 7, 1962 [Aug. 11, 1961], No. 29022/61. Headings B8H and B8J. A lifting device which is actuated upon application of mechanical pressure to a ram 38 comprises a piston 22 slidable within a cylinder 15 surrounded by a further cylinder 13 to form a space 21. The piston includes a resilient seal 23 held in position by a plug 24 which has a bore 42. A spring 26 bears on the plug 24 and urges the stem 28 of a piston valve upwardly. The head 31 of the valve is a close fit in a bore 32 in the piston, the bore constituting a valve chamber. Valve ports 33 in the piston open to the top of the piston via bores 34 or longitudinal flutes or passages around the periphery of the upper portion of the piston. A ram 38 is supported by a spring 36 resting on the piston and has a portion 39 adjacent the valve head 31. A sleeve 35 also rests on the piston. Outlets 40 provide communication between the inner cylinder 15 and the space 21 between the cylinders 13, 15. In operation, hydraulic pressure liquid enters the inner cylinder 15 through passages 12, 41, passes through the piston via bores 42, 32 and passages 33, 34 and thence into the upper portion of the cylinder 15 from which it escapes through the outlet 40 into the space 21. The liquid is drawn from this space by a pump (not shown). If a load is placed on a platform fixed or connected to the ram, the spring 36 is compressed and the ram portion 39 depresses the valve head 31. The valve ports 33 are thus closed, the flow of liquid through the piston is stopped and the ram and its load are raised. When the load is removed, the spring 36 lifts the ram, the valve 31 is allowed to rise and the ports 33 are again uncovered. The piston then descends under the weight of the ram and its platform. If, for some reason the load is not removed, the ram continues to move upwardly until the upper end of the sleeve 35 reaches a stop (not shown). The resulting increase in pressure within the cylinder causes a relief valve 17 to blow and the hydraulic liquid escapes through a passage 20 into the space 21. The hydraulic pressure may be provided by a power driven pump mounted together with the lifting device, on a wheeled chassis. The load platform may be connected to the ram by a hoisting cable, linkage or the like.

Abstract: 258,750. Tarry, G. Nov. 21, 1925. Liquid-meters.-The inlet and exhaust of liquid is controlled by oscillating perforated disc valves 8, Figs. 1 and 2, slidably mounted on squared portions 10 of a spindle 11. The valve-operating mechanism comprises springs 35 secured to arms 23, 22 carried by collars 12 fixed to the spindle and collars 13 loosely mounted on extensions of the collars 12. As the piston 3 nears the end of its stroke, the springs are tensioned by members 14 acting on the arms 22, the valves being, held by a member 5 engaging a notch 44 in one of the valves, until the piston 3 or a piston member 27 engages an extension 7 to force the member 5 out of engagement with the notch against the action of a spring 24. The piston 3 moves on a second rod 32, which passes out through a tube 33 and stuffing-box 34, and is spirally grooved so that it is oscillated and operates recording mechanism. Alternatively the rod 32 is plain and the rod 11 operates the recording-mechanism. To compensate for the temperature expansion of the liquid, a T-shaped receptacle 26 contains mercury, the expansion of which forces out a striker 27, the contact of which with the arm 7 is thus delayed; the stroke of the piston 3 is thereby increased. The valves are kept on their seats 9 by spring devices 19. Specification 170,186 is referred to.
