Abstract: 1,009,406. Welding by pressure. SIPPICAN CORPORATION. April 5, 1962 [April 11, 1961], No. 13199/62. Heading B3R. Electric resistance welding apparatus comprises separation means normally holding the tips of the welding electrodes in spaced relation and control means to render the separation means ineffective. In one embodiment, the apparatus comprises an interchangeable head assembly 10 fixed by quick release clamps 24 to a junction box 12 in turn secured to a power supply 14 resting on a work-table 16. The head 10 includes a dielectric housing 28 mounting a fixed electrode 38 and providing bearings 32 for a shaft 30 carrying an arm 34 on which is clamped a movable electrode 36. A casing comprising a cup-shaped portion 48 and an end cap 49 is seated upon shoulders 52 provided on the bearings 32 for the shaft 30 to allow relative rotation of the casing about the shaft and within the casing are a pair of spiral coil springs 64 secured at one end to the casing at 66 and at the other end to the shaft 30. A ring gear 54 on the casing is engaged by a worm 56 mounted in the housing 28 for rotation by a removable crank 60. A lever arm 44 is secured to the inner end of the shaft 30 and to rotate the shaft 30 in a direction to separate the electrodes, a bell-crank 70 pivoted to the housing has an anvil 80 urged into contact with the arm 44 by a spring 74. The spring 74 will overcome the force exerted on the shaft by the springs 64 when tensioned by rotation of the casing 48 relative to the housing 28. A rod 82 pivoted to the upper end of the bell-crank is engaged in a groove in an arm 84 secured to a shaft 86 extending across the junction box 12. An arm 88 also secured to the shaft 86 is pivoted to a link 90 secured to a foot pedal control rod 18 and normally spring urged upwardly. The link carries a leaf spring 98 to operate a switch 102. Electric bus-bars 96 extending through the junction box are connected at one end to the power supply and at the other end are releasably clamped to prongs 110 in the head 10. One prong is connected by a cable to the fixed electrode 38 and the other is connected to the inner end of the shaft 30. A potentiometer adjustable at 122 is provided and an illumination lamp 104. In operation with the electrodes apart the workpieces are positioned and the foot pedal operated to cause the bell-crank to be rotated against its spring 74 to release the arm 44 and allow the shaft 304 to be rotated by the springs 64 to bring the electrodes into contact with the work. Continued downward travel of the pedal causes the spring 98 to operate the switches 102 to allow the energization of the electrodes. In a modification, the fixed electrode is arranged below the movable electrode on an adjustable arm and the outer end of the shaft 30 carries an arm engaging a slot in a vertically reciprocable slide carrying the movable electrode. Specifications 1,009,407 and 1,009,408 are referred to.

Abstract: 570,855. Mounting lamps. WARDLE ENGINEERING CO., Ltd., and OGLEY, D. H. Aug. 23, 1943, No. 13691. [Class 78 (iii)] A T-section track 9 is laid up a chimneystack, steeple &c. in a straight line or otherwise, and a carriage 15 supporting a lamp 24 is adapted to ride up and down the track. The carriage 15 has mounted on its rear two pairs of grooved runner wheels 17 which engage the edges of the web, of the track 9. To a lug 19 is attached one end of the hauling cable which passes over a shrouded pulley at the top of the track and extends down to a winch &c. at the base of the steeple &c. The power cable for feeding the lamp 24 extends down the track and is furnished at intervals with small carriages each having a pair of grooved pulleys engaging the track web. An automatic catch for securing the carriage 15 at the top comprises a twoarmed lever 28 pivoted at 32 to the carriage 15 and while the lamp is riding up or down occupying an inclined position with the nose 34 of the rear arm 29 rubbing along the face of the web of the track 9. Near the top of the track a slot is formed in the web which allows the lever 28 to fall horizontal, when a lower rib 33 thereon bears against the carriage base 16. Lowering of the carriage 15 will then bring the lower edge of the arm 29 against the bottom of the slot and support the carriage in situ. To release the catch the carriage is raised slightly by its hauling cable, this bringing the catch 28 first to its normal inclined position by contact of its arm 29 with the top of the slot and then to an almost vertical position by contact of the arm 29 with a wedge cam extending forward from the track 9. This enables the forward nose 31 of the catch 28 to take over a cross bar 42 on a bail 41 having a slight up and down play, and to be held thereby so as to allow the carriage 15 to be lowered past the web slot to the ground &c. level. The arm 28 is of double side-by-side formation, with connecting cross bars 28a, and the web slot is similarly daplicated.
