IPC: F16F9/084
Filed: 1961-01-25
Abstract: 901,193. Hydropneumatic shock absorbers. GENERAL MOTORS CORPORATION. Jan. 25, 1961 [Feb. 4, 1960; April 13, 1960; Aug. 30, 1960], No. 2914/61. Classes 108(2) and 108(3). A hydropneumatic shock absorber in which a valved piston 14 is slidable within a cylinder 12 closed at one end by a spring-urged seal 20 and a guide 18 for a piston rod 16 and at the other end by a conventional base valve 26 which is supported by cap 34 for a reservoir tube 32 having an upper closure cap 22 is characterised in that a tubular flexible diaphragm 40 of fabric reinforced rubber is connected between the reservoir tube 32 and an annular cap member 46 which is welded to the piston rod 16 and is provided with a connection 54 for the supply and withdrawal of pressure fluid. The ends 43, 51 of the diaphragm 40 h a v e wire-reinforced beads which engage in recesses 45, 53 formed respectively in the walls of the reservoir tube 32 and the cap member 46 a tapered portion 42 of the wall of the reservoir giving a wedging action to ensure a fluid-tight seal. A port 56 in the wall of the cylinder 12 communicates with the spring pocket for the seal 20, and an aeration reducing baffle ring 38 is disposed within the reservoir 32. In a modification the annular cap member 46, having no axially extending peripheral portion, carries a tubular skirt which supports the outer wall of a more lightly constructed diaphragm 40 when the shock absorber is in the collapsed position and the pressure of the fluid within the diaphragm is at a maximum. The inner bead of the diaphragm 40 seats within an annular recess in the reservoir cap 22 the outer end being clamped between the tubular skirt and the edge of the cap 46. In a further modification the tubular skirt is equal in length to the reservoir and prevents ballooning of the diaphragm 40 when the shock absorber is in its collapsed position. The spring-urged seal 20 in all of the embodiments allows fluidunder pressure within the flexible diaphragm chamber to enter the reservoir 32. As shown in Fig. 6, a source of pressure fluid 74 is connected, through a manually operable two-way valve 76, to the shock absorbers 70 which are mounted between a chassis frame 66 and a corresponding bracket 72 shackled to a leaf spring 64. In one position the valve 76 supplies pressure fluid to a T-junction 78 leading to the connections 54 of the shock absorbers 70 and in the other position connects the T-junction to exhaust.

Abstract: 158,520. Conti, F. Jan. 24, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Rudders.-The rudders of submarines and other water craft are acted on by smaller rudders placed in front of the main rudders. Fig. 1 shows the main rudder A of a ship with forwardly-extending arms d, f carrying a smaller rudder a which is adjusted about its axis by the pilot so that the pressure thereon effects the adjustment of the main rudder. The gearing for adjusting the rudder a may be arranged within the hollow axis C and arms d, f of the main rudder or may be placed alongside them, and may consist of bevel, chain, eccentric, or other gearing actuated by pneumatic, hydraulic, or other means. When the motion of the vessel is reversed, the rudders are set free from the gearing so that they automatically take up the position with the smaller rudder foremost in the new direction of motion. The two rudders may be so connected by gearing as to facilitate their automatic return to the normal position when deflected by a side sea. Fig. 25 shows the invention applied to a jury rudder.
