Title: Device for coupling an axle to a wheel rotatable round that axle
IPC: F16D11/06
Filed: 1946-08-06
Abstract: 614,841. Clutches. FILARSKI, J. D., and GIBAS, E. Aug. 6, 1946, No. 23211. [Class 80 (ii)] In a segmental key clutch for coupling an axle 3 to a wheel hub 1 in a number of different positions, engagement is prevented when the wheel is in a predetermined unsuitable position with respect to the axle. On release of a stop pin (not shown), the key 6 carrying head-pieces 10, 14 tends to rotate in an anti-clockwise direction under the action of a spring 11. If the relative positions of the wheel and axle are unsuitable for engagement to be effected as shown in Fig. 4, one end of a lever 17 pivotally mounted on the axle engages, under the action of a spring 23, a notch 16 in the head-piece 14 thus preventing engagement of the key with the wheel. The other end 21 of the lever 17 enters a notch 22 in a ring 20 attached to the wheel hub 1. On further rotation of the wheel, the lever 17 is turned clockwise by the bevelled edge 25 of the notch 22 engaging the end 21 of the lever 17, and consequently the end 19 of the lever 17 becomes disengaged from the notch 16. The key 6 can thus turn slightly so that the notch 16 clears the end 19 of the lever 17 and the key 6 subsequently engages the notch 9a in the sleeve 2 attached to the wheel hub 1. In a modification, the axially slidable key is mounted in a sleeve keyed to the axle which may engage dogs on the wheel hub. Specification 460,664 is referred to.

Abstract: 845,161. Shearing; stamping. TRUMPF, C. July 22, 1958 [July 26, 1957], No. 23423/58. Class 83 (4). A stamping machine comprises a reciprocating ram 18, Fig. 4, carrying a die member movable towards and away from a stationary die member, a shaft 17 disposed with its axis perpendicular to the direction of movement of the ram and having an eccentric portion 22, an inner eccentric bushing 25 connected to the shaft 17 for rotation therewith, an outer eccentric bushing 39 restrained against rotation with the inner bushing 25 and connecting means e.g. a strap 21, connected to the ram 18 to impart reciprocations arising from rotation of the shaft 17, a sleeve which surrounds the shaft 17 at its journal being coupled to the inner eccentric bushing 25 and to the shaft 17. The shaft 17 is driven by an electric motor 16 (Fig. 3, not shown) and is mounted in walls 13<SP>1</SP>, 13<SP>11</SP> of a head 13 attached to the upper leg of a U-shaped machine frame. The ram 18 is constrained to travel vertically by a guide 19. The stroke of the ram 18 is adjusted by rotation of the eccentric bushing 25 relative to the eccentric portion 22 of the shaft 17, Fig. 6, the rotation being effected by a knob 32 which engages a sleeve 28 carrying a projection or key 27 which coacts with a groove 26 in the bushing 25. During the working of the ram, teeth 37, in an internal bore of the knob 32, and teeth 38, externally of the shaft 17, are urged into engagement by a spring 36 so that the shaft 17 and the bushing 25 rotate together. When it is required to adjust the ram-stroke the teeth 37, 38 are disengaged against the spring 36 and the sleeve 28 rotated, the rotation being transmitted between the knob 32 and the sleeve 28 by pins 31. The position of the ram relative to the work is determined by the angular position of an eccentric bushing 39 which is rotated by a sleeve 42 carrying a coupling bolt 41 which engages a groove 40 in the bushing 39. The sleeve 42 is rotated by a lever 46 through pins 45, the latter also allow for pivoting the lever in the direction "A," Fig. 4, to disengage a locking bolt 47 from a bore 48 in a retaining ring 43. The lever 46 is during the action of the ram spring biased outwardly so that the locking bolt 47 is engaged with a selected bore 48 thus fixing the eccentric bushing 39 against rotation with the shaft. When it is required to adjust the ram setting the lever 46 is disengaged from the retaining ring 43 and the sleeve 42 is rotated, the sleeve being again looked after angular adjustment.
