Title: Improvements relating to self centering chucks
IPC: B23B31/163
Filed: 1966-05-13
Abstract: 1,139,096. Chucks. PAUL FORKARDT K.G. 13 May, 1966 [22, May, 1965], No. 21281/66. Heading B3B. In a self-centring chuck the jaws of which are radially displaceable by means of levers 3 operated by a central axially displaceable piston 4, each lever has two coaxial cylindrical journals 5, 6 constituting a short lever arm and located in a bore 2a in the corresponding jaw carrier 2, the axis about which the lever turns being offset in the axial direction of the chuck from the axis of the bore, the jaw carrier 2 being recessed at its side opposite the face which carries, the jaw, as at 2b for the long arm of the lever and one of the two remaining walls of the jaw carrier being cut away at the rear of the journal bore by approximately the breadth of the long lever arm. In the end surface of each of the two journals 5, 6 of each lever, a transverse groove 9 is provided into each of which a corresponding blade 10 is introduced parallel to the journal axis, the blades being located on the ends of cylindrical bearing pins 11 rotatably mounted in a bore 1a in the chuck body parallel to the bore 2a but offset rearwardly therefrom in the axial direction of the chuck by a distance corresponding to the length of the required short arm of the lever 3. The two bearings associated with a lever 3 are connected with the lever 3 by a screw 12. On movement of the piston 4 to the left from the position shown in Fig. 1, the lever 3 swings in clockwise direction about the axis of the bore 1a so that the jaw carrier 2 is displaced radially inwards. In a modification (Fig. 3, not shown) the position of the bore 1b in the chuck body is offset forwardly from the axis of the bore 2a so that a displacement of the piston 4 to the left produces an outward jaw movement. In another modification (Fig. 4, not shown) the bearing pins 11 are mounted eccentrically in bushes 13 which are rotatably mounted in the chuck body and can be held in various angular positions by screws 14 so that the extent and direction of movement of the chuck jaws can be varied.

Patent GB-847048-A (GB)
Title: Fuse protective system
Inventor: GREPE FREDERICK YORKE
IPC: H01H31/12
Filed: 1958-07-04
Abstract: 847,048. Air-break switches; mechanical switches; thermal switches; protective arrangements. CANADIAN CONTROLLERS Ltd. July 4, 1958, No. 21484/58. Class 38 (5). When a lever 41 is pulled to pivot a cartridge fuse 4 away from its co-operating fuse clips 3, 53, the lever initially turns about its pivot 42 to lift a latch 29 away from a projection 30 on the upper end cap 31 of the fuse so as to release the fuse for movement. At the same time the latch 29 pivots an actuating element 26 which through a lever 24 and a link 8 opens a switch 10, the switch being maintained open by a locking element 62 which is turned by a spring 64, as the fuse is being withdrawn, into a position in which it prevents the return of the latch 29 and the actuating element 26. When the fuse is replaced, the projection 30 restores the locking element 62 so that a spring 59 returns the element 26 and the latch 29 to close the switch and re-latch the fuse. When the fuse blows, a striker pin 28 is ejected, e.g. by the ignition of an explosive charge, through an aperture in the lever 41 and turns the actuating element 26 to open the switch 10. Protective arrangements.-In a three-phase system, three of the above devices are used, the fuses being indicated at 71 ... 73 and the associated switch contacts at 14, 15. These contacts are connected in series in the circuit of the operating coil 74 of a three-phase contactor 79. Hence the blowing or removal of any fuse causes the opening of the contactor.
