Abstract: 451,858. Welding. LVOV, P. N., Pretshistenskie Vorota, Nashtshokinski Per 5 W. 22, Moscow. Feb. 12, 1935, No. 4481. [Class 83 (iv)] In electric welding - apparatus hydrostatic pressure from a water main is employed to bring the movable electrode to position and such pressure is then increased with the aid of a sinking weight and pistons of greatly differing sizes. A weight 14, which may be varied in magnitude is supported by a lever 18, attached to a bent arm 17, pivoted at 9 to a triangular lever 16 pivoted at 19 on a shaft carrying a cam 20, and also attached to a pull rod 15, which is manually operated. The movable electrode 7 is attached to the bottom 5 of a cylinder 4 sliding in a sleeve 2 and over a piston 6. The piston 6 is attached to a sleeve 3 fixed to the detachable head 11 of the cylinder. A tube 10 inside the sleeve 3 carries a small piston 12. In operation, when the rod 15 is pulled in the direction of the arrow the weight is raised and the cam 20 opens a valve 23 by operating a push rod 21. The piston 12 is raised and the electrode moved against the work. When the rod 21 is released it is returned by a spring and the weight slowly falls, the valve 23 being closed.

Abstract: 1292447 Holders for arc welding FOSECO INTERNATIONAL Ltd 27 Jan 1970 [27 Jan 1969] 4518/69 Heading H5H When handles 1, 2 of arc welding "pliers" are squeezed together electrodes 9 initially engage one another and then separate to cause an arc to be struck therebetween the intensity of the arc being adjustable thereafter depending on the degree of squeezing together of the handles 1, 2. The handles 1, 2 are pivoted together at pivot 17 and a plate 10 is mounted on the pivot 17. The tooth 5 of an electrode support 6 pivoted at 18 to plate 10 is biased by a spring 15 into engagement with an extension 4 of handle 1. An adjustable stop 13 carried by plate 10 co-operates with an electrode holding extension 11 of handle 2 so that with stop 13 abutting extension 11 a spring 12 acting between extension 11 and pivot 18 is under tension. A stop 14 limits anticlockwise rotation of electrode holder 6. When handles 1, 2 are squeezed together, extension 4 pushes tooth 5 anticlockwise against spring 15 to cause electrode 9 to engage, the stop 13 being so adjusted that the tooth 5 engages stop 14 when the electrodes engage so that they cannot be damaged by pressing them too hard together. Further squeezing of handles 1, 2, causes members 1, 6, 10 to turn together and separate the electrodes. The metal parts of the pliers are earthed by cable 16.

Abstract: 175,642. Merguin, P. Feb. 18, 1921, [Convention date]. Switches, quick-action, which, according to one construction, when turned continuously in one direction, alternately make and break contact, comprise fixed contacts 16<1> adapted to be engaged by contacts 14 on the spring-actuated rotary contact member 11, 12, 12<1>, 13, 13<1>, 14. The central spindle 3 is fixed to the base 1. On it is mounted a sleeve 8 carrying at its lower end two radial arms 9, each of which has one edge bevelled to form an inclined plane 10. This sleeve rotates with the turn-button 4, its upper end being provided with a socket 7 fixed to it and recessed so as to be engaged by the lower end of the bearing 5 of the button 4. Mounted loosely on the sleeve 8 are the contact member 11, 12, 12', 13, 13<1>, 14, comprising arms 12, 12<1>, claws 13 and 13<1> and contacts 14, and the spiral spring 15. The top end 15<1> of the spring engages in a longitudinal groove in the socket 7, and the bottom end 15<11> bears against the arm 12 of the contact member. The socket 7 is prevented from upward movement by a fork 6 engaging an annular groove 3<11> in the spindle 3. A nut 4' on the spindle 3 serves to keep the button in its place. The contact member is normally prevented from rotation by the arms 12, 12<1> bearing against teeth 21, 21' formed on the edge of a cup 20 fixed to the base. Teeth 19 are also formed on the inside surface of this cup for engagement by a spring 18 attached to one of the arms 9, so that clockwise rotation only of the arms 9 and therefore of the button 4 is possible. When the button is rotated, the spring 15 is wound up and the inclined surfaces 10 on the arms 9 bear against the claws 13, 13' and raise the whole contact member till the arms 12, 12<1> are clear of the teeth 21 or 21', a quick make or break being then effected. In a modified construction, provision is made for the rotation of the button in either direction.

Abstract: 511,358. Hosiery. INTERWOVEN STOCKING CO. Feb. 15, 1938, No. 4749. Convention date, April 16, 1937. [Class 141] [Also in Group VIII] An article of hosiery has a seamless, circular-knit, self-supporting top comprising (a) a rib-knit portion and (b) a contiguous plainknit portion having the same number of stitches per course as the ribknit portion and having elastic (e.g. rubber) thread incorporated coursewise in courses thereof. During knitting of portion (b) the elastic thread may be fed under tension to contract the portion to substantially the same diameter as portion (a). The elastic thread may be locked at spaced wales and floated on the inner face of the fabric between the locking points. The tension may draw portion (b) into vertical rib-like ridges which may form approximate continuations of the ribs of portion (a), e.g. if the elastic thread is locked at alternate wales and the portion (a) is a 1:1 rib fabric. The top may be knitted separately (and attached to the leg by stitching &c.) or integrally. The top may comprise alternate bands of (a) and (b) and the last course may be plain or rib. The portions (a) and (b) may be knit of the same thread-e.g. on a superposed double-cylinder machine having doubleended transferable needles. Fig. 4 shows a stocking top having rib-knit portions 209 and plain-knit portions 202. The portions 202 and the plain-knit welt 207 contain elastic thread 203, 207a. In modification, (a) a tubular welt, which may contain elastic threads, adjoins a rib-knit portion, and (b) the welt is replaced by a selvage consisting of an elastic thread running through loops of plain knitting.
