Title: Tapered socket connector
IPC: H01R31/02
Filed: 1964-10-15
Abstract: 1,021,979. Making electrical connections. BURNDY CORPORATION. Oct. 15, 1964 [Oct. 21, 1963], No. 42089/64. Heading B3A. [Also in Division H2] In a method of making a tapered socket connector, a metal strip is blanked to the shape shown in Fig. 1 and tongues 16a are coined to taper the thickness of the sheet. The completed sockets are joined by strips 13 which are perforated to provide engaging means for the indexing mechanisms of automatic strip handling apparatus. The sockets 16 fit in bores 34 in a housing and the bores are joined by a slot in which is located the strip body 12 (Fig. 4, not shown). The edge portion 35 abuts the surface of the housing half 32 or the sockets may be formed with an edge 17a which abuts directly against the housing half surface and have the strip body 12 in the housing half 32. A restricted bore in the body half 32 prevents the fitting of oversize pins in the socket 24 and taper pins 44 may be impacted in the sockets 16 until firmly secured. The sockets 16 are thereby expanded and fit uniformly in the bores 34.

Abstract: 1,156,625. Textile cross-winding machine. BARMAG BARMER MASCHINENFABRIK A. G. 21 Sept., 1966 [27 Sept., 1965], No. 42213/66. Heading D1J. The invention is concerned with a textile winding machine in which the speed of the winding spindle 1 and the traverse speed of the yarn guide 14 have a constant ratio but in which the rotational speed of the winding spindle is regulated to produce a predetermined rate of yarn travel. As illustrated this is accomplished by means of a control system 17 to 20 that is sensitive to the diameter of the package 2 and serves to vary the setting of core wheels 6, 7 on the drive motor 8, there being an intervening control rail 22 between said control system and the cone wheels. The control rail is replaceable by others of different shape. As the package grows the frame 17 rocks about the axis 11 to cause, the arm 20 to move the control rail 22 downwards. A rotating control member 26 acts periodically on the rail 22 to cause a member 24 to gradually displace a pivoted lever 35 serving to increase the spacing between the cone wheels 6, 7. At 'the same time the spacing between the cone wheels 3, 4 is decreased. At the start of each fresh winding operation, the pawl 41 is temporarily released from the rack 29 to permit a spring 28 to move the member 24 back towards the rotating control member 26. The control rail 22 is urged into the gap between the feeler head 23 and the control member 26 by its instrinsic weight or by a spring.

Abstract: 1,267,891. Chucks; welding by pressure. CATERPILLAR TRACTOR CO. 4 Sept., 1970 [4 Sept., 1969], No. 42542/70. Headings B3B and B3R. A chuck 12 for securing a workpiece which is to be subjected to axially applied forces during use, comprises a body 31 having a bore for receiving a workpiece WP-1, and means, such as a face ring 41, defining axially-extending ramp surfaces 34, disposed at circumferentially-spaced locations within the bore, a jaw member 33 slidable on each ramp surface 34 and having a corresponding ramp surface whereby, upon such sliding, radial movement of the jaw members will result, a ring member 37 connected to the jaw members, a draw-bar 36 connected to the ring member, and an actuator block 38 connected to the ring member and arranged to be engaged by workpiece WP-1.  In operation, jaw members 33 are tightened against the workpiece by means of the draw-bar 36 which moves the block 38, member 37 and hence jaw members 33 axially. Subsequently when axial forces on workpieee WP-1 are transmitted to the chuck by virtue of abutment between the workpieee and an end-plate 61 secured to actuator block 38, the latter moves further axially and causes further tightening of the jaw members. The latter are serrated, and retained in respective slots in face-ring 41. Springs 81 urge each jaw member to its non- clamping position. The chuck 12 may form part of an inertial friction welding machine (Fig. 1, not shown), for welding tubular workpieces. In this case, the chuck 12 and another chuck 13 have co-operable pilot members 66, 67 which engage each other upon approach and engagement of the workpieces during welding, to ensure concentricity of the chucks. The tubular workpieces surround their respective pilot members. The chuck is useful for holding workpieces of non-uniform external shape and, e.g., workpieces of hexagonal configuration.
