Abstract: 1466636 Shaft couplings I CHIVARI 9 May 1975 [29 June 1974 22 March 1975] 19656/75 Heading F2U A shaft coupling permitting radial misalignment between shaft axes (and, in some embodiments, angular misalignment) comprises first and second main coupling members 60, 62 (Fig. 3) and at least two intermediate coupling members 68, 70, rotatable relative to each other, the intermediate coupling members 68, 70 each being connected by links to each of the main coupling members 60, 62. As shown in Fig. 3 the coupling member 60 has diametrically opposite pivots 56, 58, pivot 56 being connected by a link 92 to a pivot 84 of intermediate member 70 and pivot 58 being connected by a link 96 to a pivot 82 of intermediate coupling member 68, the coupling member 62 similarly having pivots 64, 66 connected respectively to intermediate members 68 and 70 by respective links 98 and 94. The relative rotation of members 68 and 70 is provided by oil-soaked brake lining material 72 or rolling bearings 74. Three intermediate members may be provided (Figs. 8 and 9, not shown), each being linked to each of the main coupling members. In the event of radial misalignment the intermediate members rotate relative to one another and the links pivot such that the centre of the intermediate members lies intermediate the axes of the main coupling members. One or more of the intermediate members may be provided with a ring of resilient material to accommodate rotary vibrations. In the embodiment shown in Fig. 13 the links are universally articulated on the intermediate members, of which there are three, axially split, by ball-and-socket joints as shown (or alternatively by resilient material in the pivots, Fig. 14, not shown), to accommodate angular misalignment and so form a universal joint. Angular misalignment can also be accommodated by forming the links of spring steel wire which may include a loop (Fig. 24, not shown), by providing a ball-and-socket joint between the intermediate members (Fig. 23, not shown) or by forming the links of rubber bodies (Fig. 20, not shown). The links may be radially inside the intermediate members (Fig. 18, not shown). In the embodiment shown in Figs. 15 and 16, in which two identical couplings are provided, the intermediate members comprising a disc 212 and a ring 210 of substantially the same diameter which are mounted side by side with the ring 210 rotatably mounted on a boss 214 of the disc 212. Ring 210 incorporates resilient members 226, 228 between radial projections 224, 222 of an inner hub 218, to provide a torsionally resilient drive, and seals held by the projections 222, 224 and passages incorporating restrictors between spaces which contain damping fluid on either side of the seals, provide damping. The two couplings shown in Fig. 16 have a bearing 268 between them and they are connected in parallel between the main coupling members (not shown). The resilient members 226, 228 may be replaced by rubber cushions 266 (shown in broken lines). The restrictors may be adjustable.

Abstract: 1,038,232. Lathes. HARDINGE BROS. Inc. May 12, 1964, No. 19774/64. Heading B3T. In a machine, a piston-and-cylinder device for moving a part 11 (e.g. a front or rear slide of a lathe), comprises a member 42, mounted on the piston, for closing a discharge port 40 and slowing down the feed rate when the piston has moved a distance adjustable by means 29 on an extension 17 of the piston, and positive means 50 for stopping the feed after a predetermined total movement. In operation, a valve is moved to a latched-on position to cause the piston 15 to move at a fast rate until the member 42 closes the port 40. Fluid can then pass only via a line 45, 47 containing a needle valve which is adjustable to set the feed speed. At the end of the feed movement, the stop 50 abuts the cylinder ring 51 and pressure drops to cause a pressure switch to release the latch and reverse the operating valve. Fluid then enters through the port 40 and returns the part 11 to its initial position.
