Title: Improvements relating to clutches
IPC: F16D15/00
Filed: 1935-12-20
Abstract: 458,213. Friction clutches ; variablespeed gearing. KESTERTON, H. M., Gase House, Wroxall, near Warwick. Dec. 20, 1935, No. 35296. [Class 80 (ii)] A friction clutch comprises barrel-shaped rollers d, the axes of which lie in a plane normal to the clutch axis, disposed between the interior surface of a driven (or driving) drum h and the polygonal outer surface of a driving (or driven) member e which is movable axially so as to enable the clutch to be disengaged. The rollers are mounted in a cage c which is rotatable on and slidable with the member e. The surfaces of the members e, h may be inclined to the axis of the clutch. To minimize shock, a split or segmental ring j, Figs. 3 and 4, formed with recesses to receive the rollers, may be arranged between the latter and the drum h. A changespeed gear employing a double clutch is shown in Fig. 5. A single set of caged rollers d is arranged between the polygonal surface f of a sleeve e and a pair of outer members h, h<1> having oppositely-inclined interior surfaces. The member h is integral with the driven shaft i, the member h<1> is integral with a sleeve q which is rotatable and slidable on the sleeve e and is geared to the shaft i through a countershaft t, and the sleeve e is splined to the driving shaft a. A carrier 3 on the sleeve e carries a centrifugal weight 4. The sleeve e is normally urged to the right by a spring 7 so as to produce direct drive by the engagement of the rollers with the member h. On the sleeve q being moved to the left, through an arm w, it abuts against the carrier 3 and moves the sleeve e to the left, thus disengaging the rollers from the member h. A plunger 5 in the sleeve e is now opposite a recess 6 in the shaft a. If the speed of the shaft a is above a predetermined limit, the weight 4 operates to depress the plunger 5, thereby locking the sleeve e. On now moving the sleeve q to the right, the member h<1> engages the rollers and the gearing is such that an overdrive is produced. When the speed falls, the sleeve e is released and moves to the right to restore direct drive.

Abstract: 793,191. Bedsteads. HILL, W. T. Feb. 2, 1956 [Dec. 15, 1954], No. 36375/54. Class 52(2) In an invalid's bed comprising a frame in which are pivoted mattress sections, the legs section is manually adjustable and lockable in any one of a range of adjusted positions and the locking means is freed by the initial movement of the adjusting means. As shown, the frame 10 has end dovetail parts 16 and is joggled downwards at 17. The mattress consists of back, thigh and leg sections 11, 12 and 13, sections 12 and 13 being pivoted together end to end at 25. At each side, section 13 is supported from. the frame by toggle links 32, 33 which are opened and shut to raise or lower the foot end of section 13 by longitudinal movement of link 34 produced by rotation of a shaft 36 to which are keyed levers 35 pivoted to the ends of links 34. Each end of shaft 36 carries a two-part lever 40, 41 the parts of which are pivoted together at 42, part 41 being formed as a socket for a handle (not shown). Rods 45, 46 extend transversely from parts 41 and are coupled at their inner ends by a lever 47 so that as one moves outwards, the other moves outwards. Enlargements 50 on these rods engage in notches 39 in ratchet plates 38 fixed to frame 10 when the rods are urged inwards by springs 49. To adjust the leg section, the handle is inserted in one or other of sockets 41 and swung outwards. This frees enlargements 50 from notches 39' and the lever can then be pivoted forwards or backwards to rotate shaft 36 and tilt section 13. On releasing the handle, springs 49 lock the mechanism in the new position. Back section 11 is pivoted at 18 between brackets 19, 20 fixed to the frame and carries notched quadrants 55 engaged by spring-loaded pawls 58 carried by a transverse shaft 56. The pawls can be disengaged by rocking a bell-crank 61 which is formed as a socket to receive the handle, and then the inclination of section 11 can be altered by movement of the occupant's body. Adjacent ends of sections 11, 12 are coupled together by a link system 26, 27, 30 so that movement of the section 11 causes tilting of section 12 in the opposite sense, the foot end of section 12 being pivoted at 23 to the frame 10.

Abstract: 999,410. Variable speed control. PLESSEY CO. Ltd. Oct. 12, 1961 [Oct. 25, 1960], No. 36578/60. Addition to 952,982. Heading F2D. In a constant speed drive of the type described in the parent Specification, wherein constant speed of an output shaft driven through a variable ratio planet gear is obtained by speed responsive control of an air motor which controls the ratio of the variable gear and may be driven in reverse for starting the engine and testing the system during which latter the gear is locked, the air motor is controlled by a valve 3 in the delivery 1 thereof under both normal operation and testing. The valve spool 5 is biased to the left by a spring 21 and is fast. with, a piston 13 acted upon by pressure liquid supplied differentially through lines 11, 12 in response to output speed. During testing when the output speed is low the valve is conditioned as shown, wherein the outflow 1 of the air motor which is driven in reverse is vented at 9 and through the engine compressor bleed air line 7 which under these conditions is vented as the engine is stationary. When the output speed rises above the normal running speed, the valve spool 5 moves right, restricting the outflow from the air motor and thus its speed. For starting the control valve is again conditioned as shown, but when the engine has reached idling speed a piston 14, acted upon by pressure fluid supplied through a line 16 under manual control or automatic control responsive to engine speed, moves the valve spool 5 right in which position the valve spool 5 blocks the vent ports 8 and connects the air pressure supply port 7 to the air motor line 1. As the output speed rises the differential pressure in lines 11, 12 moves the valve spool 5 further right to throttle the pressure air to the motor input line 1. When the output speed reaches the constant value the valve land 5a blocks the line 1, thus holding the air motor stationary, the variable gear ratio being chosen so that the constant output speed under these conditions is attained at engine cruising speed. When the output speed rises above the constant value, the valve spool 5 moves right to connect the line 1 with the vent line 9, whereupon the variable gear drives the air motor in reverse which latter draws air from a vent and exhausts it at 9 against the resistance produced by the throttling action of land 5a. On further increase of output speed, the valve spool 5 connects the pressure air line 7 with an ejector line 18 which produces suction in the vent line 9.
