Title: Improvements in and relating to devices for stripping insulation from wires
IPC: H01R43/05
Filed: 1960-08-10
Abstract: 887,451. Insulation stripping and scrimping devices. AMP Inc. Aug. 10, 1960 [Aug. 18, 1959], No. 27702/60. Class 36. A device for stripping insulation from the ends of wires and crimping connectors thereto comprises fixed and movable closable knives 22, 24 and a pair of levers with wire-gripping jaws 66 adjacent the knives attached to a slide 58 movable towards and away from the knives, the jaws gripping the insulation after it has been cut by the knives so that when the slide is moved away from the knives, the jaws pull the insulation away from the end of the wire. An insulated wire inserted between the knives 22 and 24 operates a micro-switch (not shown) in block 28, opening a valve to piston cylinder 42, thus pulling piston-rod 40 and thus arm 38, downwards, and causing arm 30 to push blade 24 towards blade 22, cutting the insulation circumferentially between the two V-shaped edges. The micro-switch also opens a valve to piston cylinder 86, causing piston-rod 88 to be retracted allowing clockwise movement of arm 76, pivoted on brackets 78, so that cam 72, under the influence of spring 80, engages cam followers 74, forcing them apart and so closing wire-gripping jaws 66 on the wire. Further retraction of piston 88 results in the engagement of yoke 90 with bracket 94, attached to slide 58, causing the latter, and also jaws 66, to move away from the knives, stripping the cut insulation from the wire and positioning the stripped end over an uncrimped connector on the lower crimping die 8. When slide 58 energizes micro-switch 100, ram 4 moves down and a push-rod 102, fixed to it, engages an extension 104, pivoting the whole mechanism, which is mounted on a pivoted bracket 44 for this purpose, so that the stripped wire is placed in the uncrimped connector on the lower die 8 and crimping takes place. To return parts to their starting positions, air is admitted to cylinder 86, causing leftward motion of piston-rod 88, disengaging arm 76 from cam followers 74, and opening jaws 66. In a modification, a piston cylinder replaces spring 80 and cylinder 86 is linked to slide 58 by a pivotally-mounted lever (Figs. 9, 10, not shown).

Abstract: 367,818. Counting-apparatus. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Sept. 17, 1930, No. 27789. Convention date, Sept. 17, 1929. [Class 106 (i).] The movements of counters at a distance are summed by electric impulses subject to a time displacement, as between the various counters, by means of relays across the counters and rendered operative in a prescribed order under the control of a rotary switch or of a main relay. In the arrangement shown in Fig. 1 the switch 3 has two wipers for moving over contacts wired by two lines to each station and is automatically stepped by a self-interrupting circuit. If a particular counter has closed its contacts 1, circuit is completed through resting contact 2r of relay 2 and one wiper of the switch to relay 7 to effect at 8, 9 a count of one. Both wipers in combination simultaneously cause operation of the relay 2 which then locks up at 2a until the contacts at 1 separate. In a modification of this arrangement, Fig. 2, a third contact 2r2 of relay 2 serves, when the counter contacts close, to connect up a relay 10 for starting the switch in rotation, a pair of cam-operated contacts 11 ensuring a complete turn of the switch when started. In the further modification shown in Fig. 3 the switch is replaced by a relay 14 and an additional relay 13 is provided at each station. Closure of a pair of contacts 1 causes energization of the corresponding relay 13 by way of contacts 2r, 14r. The relay then locks up at 13a3, at 13a2 prepares a circuit for relay 2, and at 13a1 completes a line to relay 10 to energize relay 14. The last-named on operating effects at 14a1 the advance of the main counter 8 and through 13a2 the energizing of relay 2 which then locks up until contacts 1 open. Relay 14 releases through the action of a relay 6 and may then be again energized through any other relay 13. The closure of contact 14a1 extends the negative potential to the relays 13 linked together by means of their contacts 13r so that if two or more signals are awaiting registration the relays are cleared in succession commencing at the nearest.

Abstract: 395,351. Assembling and seaming can heads and bodies. ARMSTRONG, J. J. V., 12, Church Street, Liverpool.- (Continental Can Co., Inc. ; 100, East 42nd Street, New York, U.S.A.) Oct. 12, 1931, No. 28257. [Class 83 (iv).] A machine for securing ends to can bodies includes a mechanism for clinching the lids to the cans and a second mechanism for effecting the seaming in vacuo stop devices for each mechanism being provided, that for the seaming mechanism also controlling the clinching mechanism. Filled cans a, Fig. 1, are fed to a channel A<2> and moved forward by a conveyer screw a<3> to a turntable a<4>, from which a star wheel conveys them to the clinching mechanism A<1>. The ends a<1> are fed from a magazine and transferred by a star wheel a<6> to an arcuate guideway a<5>, Fig. 4, between two plates a<7>, a<8>, and then pass to the can bodies before entering the mechanism A<1>. The bodies and ends are carried after clinching by a conveyer 29 to a vacuum chamber 30 and then to a further vacuum chamber 31 for seaming, after which they are returned to the chamber 30 and discharged to a platform 32. The main drive shaft 20, Fig. 9, for the clinching mechanism carries a clutch 21 which may be actuated manually by a lever 22a or automatically by energization of a solenoid 27, Fig. 10, which attracts a core 63 to rock a bell crank lever 65 and move a valve 61. A source of vacuum 62 is thereby put into communication with a pipe 62a and cylinder 25 to move a piston 24 to the right and operate the clutch through the rod 22. A clutch for the seaming mechanism is controlled in a similar manner by a solenoid 34. The solenoid 27 is energized by rocking switch 94 or 50, Fig. 16, each comprising a pair of mercury-tube switch elements. Switch 94 is operated when the supply of lids in the magazine falls short by a mechanism such as that described in Specification 395,352, while switch 50 is operated when a lid fails to be delivered. An arm 44 on a shaft 45, Fig. 4, depending in the path of the ends a<1> is rocked by the passage thereof to raise an arm 46, Fig. 9, to declutch members 40, 43 and allow the arm 40 to be swung idly by a can body a, Fig. 1. When the clutch remains engaged on failure of the supply of lids, rotation of the arm 40 rocks the switch 50 through shafts 41, 54 to stop the machine. Energization of the solenoid 34, and also of the solenoid 27, to stop both parts of the machine, is effected by a switch 33 in the chamber 30 upon failure of the vacuum therein, or by a switch 79 upon failure of the vacuum in the chamber 31, by mechanism of usual construction. Illumination and indicator lamps 37, 38 are extinguished on operation of the switch 79, but may be temporarily put into circuit by movement of a doublethrow switch 39 to its dotted-line position, Fig. 16.
