Abstract: 833,948. Joint-making packing; stuffing- boxes. COMPAGNIE DE PONT-A-MOUSSON. March 7, 1958 [March 13, 1957], No. 7368/58. Classes 122 (3) and 122 (5). An elastic sealing ring G1, Fig. 1, is reinforced by at least one endless spring Aa which is formed of coils of periodically varying shape, the outer similar-shaped coil portions 3 of the coils being flush with the outer surface of the ring and superposed one on another, and interconnected by the inner coil portions 4 which are embedded in the ring. As shown in Fig. 3, applied to a pipe joint, a reinforcement Aa is moulded into each of three corners of a rubber body 1, in order to prevent extrusion of the rubber through the clearance between the pipe T1 and socket T2 and other parts of the joint. The reinforcement Aa, Fig. 4, may be in the form of a rustless or plastic-covered wire spring in which the alternate coils 3, 4 are of circular and oval shape, the parts d, e, f of adjacent coils being in abutting relationship while a gap is formed between the portions d, h, f of the coils 3 thus allowing the flow of rubber therebetween during the moulding process. If desired the oval coils may be disposed at various angular positions about the axis of the coils 3. In modifications, the reinforcement may be formed (a) solely from oval coils which deviate alternately to the right and left, (b) from alternate groups of circular coils 3 and oval coils 4, (c) from square coils alternating with crossed triangular-shaped coils, and (d) from alternate semi-circular and circular coils. The surface of the wire forming the coils may be knurled or grooved.

Title: Improvements in or relating to friction clutches
IPC: F16D13/69
Filed: 1945-03-28
Abstract: 614,913. Friction clutches. CHURCHILL & CO., Ltd., C., and MOULD, C. H. March 28, 1945, No. 7826. [Class 80 (ii)] In friction clutches of the kind having two or more relatively axially movable driving or driven plates, compressible resilient material such as oil resistant or other synthetic rubber is located between some or all of the plates to urge them apart upon clutch disengagement. As shown, applied to a multi-plate clutch having externally and internally splined driving and driven plates 22, 20 respectively, resilient blocks 30 are mounted on either side of the splined portions of each alternate driving and driven plate so as to clear the adjacent driven or driving plate and co-act with the next driving or driven plate respectively. Alternatively, the blocks may be mounted upon one side only of every driving or driven plate. The blocks may be of rectangular, circular or V-section, or, as shown in Fig. 4, where geartooth splining is used the blocks may be shaped correspondingly. They may be disposed between some or all of the spline projections on each plate, and those between the driven plates may be either axially aligned or cireumferentially stepped with regard to those between the driving plates. Where the plates are suitably shaped, the blocks may be replaced by continuous annular rings of compressible material. With thin clutch plates, the blocks 30, Fig. 6, may be arranged to act between non-consecutive driving or driven plates, passing freely through gaps in the intermediate plate or plates 36 of the same type. In this case the various blocks round the axis may be attached to different plates so that every plate is resiliently acted upon by a block or blocks. The blocks may be secured to the plates by direct moulding, by attachment to a metal stud which can be affixed, as by rivetting, to the plate, by one or more pins 42, Fig. 8, slidable in the plate and having a locating head 46, or by being themselves formed with a headed shank adapted to be pressed through a hole in the plate. Where a single plate carries registering blocks 52a, 52b, Fig. 10, on either side, these may be of unitary construction with a resilient or other shank 54 received in a radial slot in the plate. If the shank is resilient the slot may be of dovetail or keyhole form or otherwise undercut to provide locking. T- shaped slots receiving circular double blocks with resilient rectangular shanks shaped to fit the heads of the slots are shown in Fig. 14. The blocks may have metal or other protective facings 56, Fig. 8. According to the Provisional Specification, the means of moving the driving and driven plates relatively to one another may consist of an operating mechanism of the kind described in Specification 614,905.

Title: Improvements in hydraulic-operated clutch controls for automobile vehicles
IPC: F16D48/02
Filed: 1965-02-23
Abstract: 1,095,725. Clutch control. SOC. ANON. ANDRE CITROEN. Feb. 23, 1965 [Feb. 28, 1964], No. 7845/65. Heading F2L. An hydraulic circuit for simultaneous control of the friction main clutch and the engine throttle of a motor vehicle giving rapid initial engagement and gradual final engagement of the hydraulically disengaged clutch, the change point from rapid to gradual movement being determined by the engine throttle position, comprises, between a manually or automatically actuated gear ratio selection and clutch control valve 3 and a clutch disengaging jack 8, a device 1 having valve spools 6, 7 urged leftwards in a bore 48 by a spring 37 and the fluid pressure existing in the jack 8 and rightwards by a spring 27, acting through a lever 28, the tension of which spring 27 is controlled by the angular position of the engine throttle spindle 21 by means of a cam 22 and a lever 25. Movement of the valve 3 to a clutch disengaged position admits fluid pressure through a line 2, ports 43, 44, a chamber 35, and a line 46 to the clutch jack 8, and through a line 20 to a cylinder 15 where it acts to move a piston 16 leftwards against a spring 17 to act on the cam 22 to limit the engine throttle opening to e.g. 2/3 maximum, a sleeve 19 limiting the travel of the piston 16. The line 20 may include a one-way restrictor (Fig. 4, not shown) to prevent rapid throttle closure. Fluid pressure in the chamber 35 moves the spools 6, 7 leftwards to fully open the port 43 to the bore 48. The distance between the lands of the spools 6, 7 is slightly less than the distance between the ports 43, 44. When, for clutch engagement, the line 2 is exhausted by the valve 3 to a reservoir, the fluid from the clutch jack 8 passes rapidly through the port 43 until the jack pressure is overcome by the action of the spring 27 and the spools move rightwards to close the port 43. The remaining pressure is then released more slowly by leakage at a predetermined rate round the spool 7 from the port 44. The spring 17 returns the piston 16 to release the throttle. The tension of the spring 27 is adjustable by a screw adjusted opposing spring 30.
