IPC: H01R43/033
Filed: 1966-12-01
Abstract: 1,216,465. Wrapping electric terminals. POST OFFICE. 29 Feb., 1968 [1 Dec., 1966], No.53945/66. Heading B3E. A wire wrapping tool comprises a driving member operatively connected to a wire wrapping head and insulation stripping means, the wrapping head having a longitudinal bore for receiving a component to be wrapped, the wall of the bore being adapted to receive internally a member resiliently biased to protrude into the bore, the member being displaceable against the bias to allow a component to enter the bore. The tool comprises a driving shaft 1, having a reduced diameter extension 6, and which is received in a sleeve 3. Secured to each end of the sleeve are bushes 4 and 5. A screw 8 is engageable with any one of the recesses 9 to lock the sleeve to the shaft. A hand grip 10 is rotatable on the sleeve 3 and has a handle 11. A recess 12 in the hand grip leads to a shallow groove 13 which opens through the end face 15 of the hand grip. A similar groove 18 in the bush 5, creates an edge which co-operates with an edge of the groove 13 to form a wire-cutting shear. The wire is retained in the groove 18 by an arcuate spring 19, secured to the bush 5 by a screw 21. A stem 7 which is a slide fit in the sleeve 3 is locked in position by a screw similar to the screw 8 and is tapped to receive the threaded end of a head piece 22. Clamped between the stem 7 and the head piece 22 are a wire guide 23 and a spring steel insulation stripper 24. The wire guide has a tangential slot through which the wire can be inserted in the eye of the guide. The wire stripper 24 extends along the head piece 22 and has a portion 32 which bends away from the head piece and forms a collar 33 part-way around the head piece. The head piece 22 is tapped to receive the wrapping head 26 which has a central bore and a slot 27 through the wall. An annular groove around the wrapping head receives the coiled end of a piece of spring wire 29, which passes through the slot and terminates in an L-shaped hook. The wrapping head has an enlarged end which clamps a washer 30 having a notch 31 in its periphery, one side of which is straight and radial and the other side convexly curved. The notch 31 co-operates with the tapered end 34 of the collar 33 to form an insulation stripping notch. Operation.-The wire to be used to wrap a terminal is hooked under the wire 29 and the tool placed on the terminal. The wire is pulled taut, the portion 32 of the wire stripper pressed in, to open the entrance to the notch 31 and the wire placed in the notch. When the portion 32 is released the end portion of the stripper cuts through the insulation but does not touch the wire, the position of the washer relative to the collar 33 having been adjusted to obtain this result. The wire is passed through the slot into the eye of the guide 23 and is pushed under the spring 19 and into the grooves 13 and 18. Rotation of the shaft by hand or power means causes the wire to be cut and then drawn through the stripping notch as it is wrapped on the terminal.

Abstract: 1,164,328. Change speed gear. DAVID BROWN GEAR INDUSTRIES Ltd., and H. EBERT. 6 Oct., 1967 [3 Dec., 1966], No. 54218/66. Headings F2C and F2D. In a split-torque change speed gear for a motor vehicle of the type described in Specification 1,164,326 wherein a torque splitting planet train 14 divides the torque between a mechanical path 18 and a hydrostatic path 20, 21, 22, a make-up pump 27 for the hydrostatic transmission 21 is driven from the input shaft 11 during normal drive and is driven from the output shaft 18 when the driving shaft 11 is stationary and the output shaft is rotating, to permit tow starting. During normal drive a pinion 33 fast with the planet carrier 14 of the torque splitting train drives the pump 27 through a pinion 29 and one-way clutch 31. During tow starting the input shaft 11 and planet carrier 14 are stationary and the output shaft 18 drives the pump 27 through gears 17, 16, 19, 34, 30 and a one-way clutch 32. When the hydrostatic transmission is primed and pressure is supplied by the pump 27 to engage a clutch 24 between the motor of the hydrostatic transmission and the output shaft 18 a drive is transmitted from the output shaft 18 to the ring gear 19 through the hydrostatic transmission in a direction opposite to that transmitted to the gear 19 from the shaft 18 through the gear 16. The planet carrier 14 and input shaft 11 are thus rotated to start the engine. The drives to the pump 27 may be replaced by belt drives and the one-way clutches may be located at other positions in the drives to the pump 27.
