Title: Improved clutch mechanism
IPC: F16D11/14
Filed: 1929-06-28
Abstract: 334,649. Morgan, H. R. June 28, 1929. Clutches, claw. - A claw clutch is adapted to have on initial engagement a limited amount of backlash to be taken up by further coupling means actuated by the torque of the drive. These means may comprise a further dog clutch, a series of teeth to fill the backlash spaces of the prior set, or, as shown, a series of spring-pressed bolts C<1>, C<2> closely engaging holes B<1>, B<2> in one of the coupled members A. The other coupled member D<1> on the shaft D has splined to it a member F, carrying undercut teeth, O<1>, O<2>, pressed forward by a spring K to engage, with considerable backlash, teeth E<1>, E<2> on the member A. The bolts C<1>, C<2> are carried in guides in the member F and are pressed forward by springs I bearing on a washer N attached to the member F. Slidable on member D' is a part L which is slid axially to affect disengagement, first of the bolts C<1>, C<2> through lugs J carried thereon, thereby establishing a condition of backlash, and then of the dogs O<1>, O<2> against spring K. On engagement, by reason of the undercut faces of the dogs the drive acts by force and momentum to draw the prior set O<1>, E<1>, Fig. II into closer engagement, first compressing the springs I and finally allowing the bolts C<1> to engage their recesses. The compressing effect of the springs I may be used as a cushioning device and the springs I may accordingly be stiffer than ordinarily necessary. In a modification, only one face of each set of prior engaging teeth is undercut, the other face being straight and having alongside it the locking teeth which fill the backlash space. In a further modification, a sliding dog is splined to the outer surface of the prior engaging member and comes into close engagement with peripheral teeth on the driven member. The device is enclosed in a casing and provided with an operating fork.

Abstract: 898,139. Fluid-pressure servomotor-control systems; valves. BRITISH PETROLEUM CO. Ltd., and WILLIAMS, P. G. Aug. 5, 1960 [June 12, 1959], No. 20147/59. Class 135. A liquid flow control system comprising a pressure control valve 16 having an actuating mechanism 18 which is hydraulically controlled by applying a variable pressure differential thereto, the valve being connected at the downstream side thereof to a Venturi 8, means 14, 25 adapted to vary the pressure differential within the actuating mechanism of the valve and, in consequence, to reduce the flow through the Venturi when the pressure differential between the fluid in the throat of the Venturi and fluid at a pre-set pressure exceeds a given value, and means 26, operating in response to movement of the actuating mechanism of the valve, for providing control of a pump 2 connected at the up-stream side of the Venturi. The pump, which may be driven by an internal combustion engine 30, forces liquid via pipe 3, filter 4, pipe 5, flowmeter 6, valve 7, and Venturi 8, through a pipe 9. With the valve 7 open and increase in pressure in the pipe 9 causes the pressure in the pipe 25 to act on one side of a diaphragm 24 constituting the actuating mechanism 18 and thereby to open the valve 16 against a pre-set pressure on the other side of the diaphragm, fluid then being by-passed via a pipe 17. Movement of the valve 16 causes a piston valve 26 connected thereto to move and, via pipes 27, 28, piston 29, control a throttle 32 of the engie 30 and so reduce the output of the pumps When the valve 7 is closed, in order to prevent the reduced pressure in the throat of the Venturi from tending to close the valve and so cause the pump to increase speed, a piston 12 is connected across the valve 7 and actuated in response to the high pressure differential so as to open a valve 21 and thereby bleed-off the pressure in the chamber 19 above the diaphragm via pipes 20, 22. A second pipe 9a may be supplied by the pump and provided with duplicated parts as shown.
