Title: Improvements in and relating to automatic weft replenishing mechanism for looms for weaving
IPC: D03D45/20
Filed: 1930-03-11
Abstract: 349,177. Weft-feeler arrangements for looms. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Crompton & Knowles Loom Works ; Worcester, Massachusetts, U.S.A.) March 11, 1930, No. 7874. [Class 142 (iii).] Automatic weft replenishing mechanism for looms for weaving double pile fabrics is augmented by the provision of a device which is positively actuated in part by the shuttle to be replenished when in correct longitudinal position for transfer, to set the transfer mechanism in operative condition, the weft detector only ensuring a preliminary setting of said mechanism. A weft feeler or detector 17, Fig. 1, mounted on the breast beam 13, is rocked when the weft is substantially exhausted and moves a control wire 20 into a position below the end of a lever 23, Fig. 3, thereby forming a pivot for the latter when it is lowered by a reciprocating bar 22 having a twostage downward movement. The lever 23 engages a pin 29 on a control lever 27 which is connected by a cord 33 to a detector lever 55, Fig. 5, mounted on the other side of the loom, and during the first part of its downward movement allows the lever 55 to be rocked by a spring 57, thereby compressing a second spring 53 associated with the device. During the second movement of the bar 22, which occurs during the second beat-up when the shuttle is on the magazine side of the loom, the control lever 27 is depressed still further, and the spring 53 gives a rocking movement to an indicator transmitter 50 to bring the inclined face 59 into the path of a finger 60 on a pivoted shuttle feeler 61 mounted on the lay. As the lay advances, a screw 64 on the shuttle feeler is pushed through an opening in the shuttle box until it is stopped by engagement with a correctly positioned shuttle, whereupon a rocking anticlockwise movement is given to the transmitter 50, which moves a push wire into contact with a, hook 45 on a reciprocative actuator 44, causing it to engage a lug 48 on an actuating lever 43 associated with the transfer slide 41, which transfers a bobbin from the magazine into the shuttle. If the shuttle is not properly placed, the spring 53 will resist expansion, and as a result the shuttle feeler will rock on its pivot, the screw 64 passing beyond the front of the shuttle box and the wire 49 and hook 45 remaining as shown in Fig. 5 to prevent transfer.

Title: Improvements in or relating to arc-rupturing devices for electric circuit-interrupting apparatus
IPC: H01H9/44
Filed: 1926-03-24
Abstract: 249,870. Metropolitan-Vickers Elec-. trical Co., Ltd., (Assignees of Austin, B. 0.). March 26, 1925, [Convention date]. Sparking, preventing.-A heavy current circuitinterrupter is provided with a magnetic blow-outconsisting of arcing tips 25, 26 and 36, 37 of U- form, one limb serving as the arcing tip proper and the other limb serving to conduct the current to the tips and to the fixed and movable contacts 27, 43 which are in metallic connection with the tips. The switch shown is pneumatically operated, and when the pressure is removed the piston 34 falls carrying with it the movable contact 43 and the lower arcing tip &c. connected with it. As the main contacts separate, their inner ends incline towards one another under the action of the spring 44 as shown, so that the arc forms at the inner ends. The upper U-shaped arc-tip encloses a magnetic core 28 which has extended polepieces 30 located outside an arc chute 45. The pole-pieces 30 support further pole-pieces 40 extending to the neighbourhood of a second magnetic core located in the lower U-shaped horn. The blow-out field thus produced draws the arc from the contacts on to the arc tips and as, under the magnetic influence, the arc is lengthened, the current path includes a greater length of the U- shaped tips and, consequently has a greater magnetic action producing a greater blow-out action.

Title: Improvements in or relating to fastening devices
IPC: A45C13/10
Filed: 1958-03-13
Abstract: 860,956. Stud and socket fasteners. WALDES KOHINOOR Inc. March 13, 1958 [April 6, 1957], No. 8090/58. Addition to 752,172. Class 44. A fastening device comprises male and female fastener elements each attachable to a member 7, 12 to be fastened, the female element comprising a generally rectangular frame-like casing and the male element being insertible in said casing and comprising a rigid stud having a pair of upright end walls provided with outwardly facing recesses, a resilient clamp 3 contained within the casing for releasably clamping the stud to the casing following its insertion therein, said clamp 3 extending substantially the length of the casing and being maintained in a state of endwise contraction whereby it possesses the potential of reversing from a stable convex to a stable concave configuration and vice-versa and clamping fingers depending from the end edges of said clamp and being projectible into and retractible from the stud recesses with reversal of said clamp. As shown in Fig. 2 the clamp 3 is itself resilient and it is maintained in the state of endwise contraction by arms 16 which are formed integral with and extend upwardly from a flange 17 which is fixed to the underface of the member 7 by the rivets which secure the casing 1 to the member 7. The ends of the arms 16 extend towards one another at an obtuse angle to retain the clamp in position. The clamping fingers 14,14a are spaced on the end edges of the clamp and the arms 16 engage the clamp between these fingers to maintain it in a bowed state, so that when the clamp is in its convex state the fingers 14, 14a engage the recesses 9 in the end walls 8 of the stud 2. In a modification, Fig. 10, the arms 16 are omitted and instead the resilient clamp 3 is formed with contracting means 25, 26 which are separated from a reversible elongate part 23 by slits 24. The length of the contracting means 25, 26 is reduced by forming them with transverse corrugations 27. In a different modification in which the arms 16 are employed, the clamp is made more elastic by providing it with one or more transverse corrugations. In an alternative construction Fig. 13 the clamp 53 has two rigid end portions 55, 55a each of which is formed with clamping fingers 54, 54a to engage recesses in the stud 52 and the portions 55, 55a are positioned between abutments 57, 57a forming the contracting means so that a spring 56 is compressed between the two portions. In a modification of this construction the two portions are hinged together and a coil spring is connected between them.
