Patent GB-908141-A (GB)
Title: An improved device for making electrical connections
Inventor: TRAPP CHARLES CARL
IPC: H01R43/033
Filed: 1958-03-11
Abstract: 908,141. Stripping insulation. ERICSSON TELEPHONES Ltd. March 6, 1959 [March 11, 1958], No. 7721/58. Class 36. [Also in Group XXII] Apparatus for wrapping wire or wires round a terminal comprises a rotatable mandrel having a bore within which the terminal is received, means for locating the wire to be wrapped parallel with said bore and means for rotating the mandrel and the wire relative to the terminal to wrap the wire therearound. A mandrel 24 is rotated by gears 3, 4 driven by an electric motor housed in a pistol grip 1 of the tool. The mandrel 24 is formed at its outer end with a bore 25 to receive the member to be wrapped and with a flattened part 34 having a groove 26 along each side to guide the end of the wire or wires being wrapped. Fingers 15 extend along the mandrel and are held thereon against leaf-springs 18 by a sleeve 14 adjustably threaded on a part 13 of the tool housing 1. The outer end of each finger 15 is formed with a recess 32, registering with the bore 25 in the mandrel, and with a pair of recesses 31 having conical end portions 35, registering with the grooves 26. Tapered external surfaces 28 on the finger ends co-operate with an internal tapered surface 27 on the sleeve 14. In operation the sleeve 14 is partly unscrewed on the thread 13 to allow the fingers 15 to open. Insulated wire is then laid along one of the grooves 26, so that its end abuts and is positioned by a saddle 21 adjustable along a slot 23 in the mandrel 24, thus determining the length to be wound. The sleeve 14 is then screwed up on the thread 13 to close the fingers 15 an amount sufficient to cause the recesses 31 to nick the insulation of the wire and the sleeve is locked in this position by a latch 10 thereon engaging the appropriate one of a series of radial slots 37 on the housing 1. The extending wire is then bent at right-angles and laid in a slot 29 in the end of the sleeve 14. The tool is then applied to the member to be wrapped, which passes into the bore 25, and a trigger 2 is pressed to rotate the mandrel 24 to wrap the wire around the member, insulation being stripped from the wire by the recesses 31 as it is drawn therethrough The stripped insulation falling through slots 19 in the sleeve 14 or being expelled by centrifugal action or air jet. As the wire is wrapped the member moves out of the bore 25. Alternatively the saddle 21 may be removed and the wire passed through a bore 7 in the end of the mandrel, through the slot 23, along a groove 26 and through the recesses 31 to the member to be wrapped.

Abstract: 1,016,453. Hay - conditioning apparatus. INTERNATIONAL HARVESTER CO. March 1, 1963 [March 2, 1962 ; Dec. 1, 1962], No. 8260/63. Heading B2A. The hay conditioner of the parent Specification is modified by the provision of a further roller-carrying structure 8, 23, 21, Fig. 1, which is articulated in a substantially vertical plane so that when it is moved by the main articulated frame 5, 13-16 supporting the rollers 1, 2 it operates to move them together or apart, and the arm 21 is pivotally mounted at 18 to the arms 13 of the frame with one end linked to the carrying structure and the other positioned to abut the draft source for the hay-conditioner so that, in the lower position of the rollers their spacing is variable under spring load, and in the raised position the pivotally mounted arm abuts the draft source in a position in which the rollers are apart. When the rollers become choked, or for transport, the implement is raised by hydraulic lifting arms 14 comprised in the frame 13-16 so that the angle A formed by the arms 13 and the structure 5 increases, and the lever 21 is rotated counterclockwise so that the rear end of the arm 13 is moved away from the structure 5, lifting the end 10 of the arm 8, which acts with the spring 11 and the structure 5 as a toggle, thus separating the rollers. When the rollers are lowered, they are maintained in contact by the weight of the upper roller 1 and the toggle-spring 11, the driving belt (not shown) for the rollers being arranged to be in greater tension when the rollers are up. In a further embodiment, series of holes 25, 26, 32, Fig. 4 (not shown), provide for adjustment of the positions of the linkages. When the rollers are blocked the arms 14 of the hydraulic system lift so that a stirring member 29, Fig. 4, contacts upper arm 16, further lifting actuating all the levers so that angle B decreases, the stirring rotating anticlockwise with the arm 16, and levers 21 are actuated, and act on arms 8 through links 23 to separate the rollers.

Vulcanizing, moulds, cores &c. for.-In the manufacture of rubber tyres by the internal-pressure system, the mould shells A, B for the tyre casing L are mounted in or form part of containers C, D arranged to provide spaces which are always in communication with the pressure-fluid supply pipe and from which, as soon as the mould is closed, such fluid can be supplied to the space within the tyre casing. As shown in Fig. 2, the shells A, B are mounted in the containers by screws E and the containers, together with their disk-like extensions C<1>, D<1>, provide a pressuretight space with which the pressure fluid supply is in permanent connexion. The two containers are held together by bolts M and, if desired, by inner bolts M<1>. Pressure fluid is supplied to a channel formed between an upstanding flange B' and the inner surface of the core L', and a vent L<4> in the core allows escape of air from inside the tyre casing. The heating spaces around the moulds may have a separate supply of heating fluid, and in order to heat up quickly, a reserve of hot fluid is provided in a steam-heated vessel H<1>. The containers are preferably horizontal, as shown in Fig. 8, the lower one being fixed and in permanent connexion with the pressure fluid supply and the upper hinged to it and adapted to be opened and closed by means of an hydraulic cylinder K<1> and balance weight K<6>. As shown in Fig. 9, the moulds may be arranged back to back and in rows, each row being served by an overhead runway N, and, further, the moulds may be in groups so that while one group is being emptied and filled another may be closed with casings under treatment. A number of modifications are described involving slight differences as regards shape and relative disposition and attachment of the disks C<1>, D<1>, the mould shells and the heating spaces adjacent the mould shells. As regard the cores, they may be solid as shown in Fig. 2, or collapsible, or in the form of an inflatable tube L<3>, Fig. 7, in which case the pressure supply tube L<2> is pulled against the core ring L<x> by a nut to prevent ingress of air.
