摘要： 617,643. Tubular lamp fittings. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and STEVENS, R. W. Sept. 27, 1946, No. 28978. [Classes 75 (iii) and 75 (iv)] [Also in Group XXV] Means for locking together two adjacent fittings for tubular electric lamps in an end to end arrangement comprise a separate locking member engaged by one or more hook-like members on each fitting when the two fittings are brought into aligned contact with the locking member ; when the fittings have substantially flat end plates the locking member is a thin strip or plate which is sandwiched between juxtaposed end plates. When the locking member is suspended from a ceiling it. serves also to support the fittings. A locking member 9 comprises a thin strip 10 having a horizontal portion 11 and a supporting member 12 adapted to hold captive a bush for a depending conduit, the bush being free to rotate and move along a slot 15 in the member 12. Two downward hooks on an end plate 3 of a tubular lamp fitting 1 engage over the horizontal portion 11 of the locking member and enter slots in an end plate of an adjacent fitting 2 which is likewise provided with downward hooks 6 engaging the horizontal portion 11 and entering corresponding slots 7 in the fitting 1. Spring latches 13, 14 on the locking member engage the tops of the fittings. In a modification the supporting member 12 on the locking member 1 is replaced by a hook suitable for chain suspension. Specification 606,403 is referred to in the Provisional Specification.

摘要： 606,404. Electric lamp supports. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and STEVENS, R. W. Jan. 14, 1946, No. 1296. [Classes 75(ii) and 75(iii)] [Also in Groups XXV and XXXVI] An electric lamp support consists of two interengageable parts, one attached to the suspension means 20 and the other to the light fitting, the two parts being automatically locked by a uni-directional linear motion and unlocked by a turning movement through a fraction of a revolution. One part may be a pin 9 secured in an insulating bush 12 in the fitting by locking nuts between which is a tagged washer for a lead 13, the pin being proviaed at its upper end with grooves 11. The other part may comprise two spring fingers 21 secured to a plate 22 attached to an insulating disc 16 surrounded by a metal ring, 17, a shrouded cup 18 being screwed to the disc 16 and ring 17 and having an aperture at its upper end to receive a flared collar 19 for a conduit 20. Electric leads may be passed through the conduit 20 and attached to a bolt securing the plate 22 to the insulating disc 16 so as to complete an electric coupling when the pin 9 is in position. To support the fitting the pin 9 is inserted in the central aperture of the disc 16 and the cup 18 is rotated, if necessary, until the fingers 21 engage in the grooves 11. The tip of the pin may be bevelled so that the fingers ride automatically into the grooves. Wire springs or spring urged plates may replace the fingers 21 and the pin may be attached to the suspension means and the cup 18 to the light fitting. The coupling may be disconnected by rotating the cup 18 till the springs 21 ride out of the grooves 11 when the fitting may be withdrawn. The fitting may have hooked portions 7 and wing nuts 8 to support side panels as described in Specification 606,403, and the wing nuts may terminate in grooved pins adapted to be engaged by springs similar to the springs 21.

摘要： 581,119. Street lamps &c. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and STEVENS, R. W. April 20, 1945, No. 9994. [Class 75 (iv)] In a street lighting or other lighting fitting comprising an inverted trough or cup-shaped body 1 of badly conducting material such as concrete supporting an incandescent or mercury vapour electric lamp or other light source 7, a number of tubes 8 of copper, aluminium or other good conducting material are provided in the cup space 3 and pass through the body 1 to communicate with the free air at different levels so as to dissipate the heat produced by the lamp. The tubes may be corrugated or formed with fins and their lower ends may terminate in a channel 10 in the body 1 leading to a drainage duct 11. The fitting may be closed on the underside by a transparent globe 12 and a screen 9 may be provided to deflect the hot rising air on to the tubes 8. A steel conduit 5 extending through an arm 4 cast or moulded integrally with the body 1 serves as the passage for the electric conductors or fuel to the light source.

摘要： 416,782. Lifts; distributing stress uniformly. EXPRESS LIFT CO., Ltd., and STEVENS, J. W., Greycoat Street, Victoria Street, London. Feb. 18, 1933, No. 5067. [Classes 78 (ii) and 78 (iii).] Travelling towers in general, and more especially those which support a lift cage travelling on guides inside them, are prevented from distortion by a system of tensioned ropes and counterweights which equalize the hauling strain. The invention is applicable specially to storied garages wherein ranges of storage compartments situated at different levels are served by the traversing of the tower and raising and lowering of the lift. Fig. 3 shows one arrangement in which ropes 6 fixed at different levels to the tower are given a few turns round drums 16 and then pass to a single counterweight 7 on each side of the tower. By rotating the drums simultaneously in opposite directions, through the medium of the motor 20 and bevel shaft 19, one weight 7 may be raised and the other one simultaneously lowered, thus effecting the traversing of the suspended tower on the runway 5. The drums 16 may be omitted at one side of the appliance, the traversing in one direction then being effected by the one counterweight when the opposite one is raised by the driving-gear. The two ropes 6 at one level may be replaced by a single rope connected at two points to the tower. The lift 2 is raised and lowered by hoisting-gear 3 on the travelling carriage supporting the tower. Figs. 1 and 2 show a modified arrangement in which the ropes 6 pass upwards over drums 9 on a driven shaft 11 and thence round pulleys 15 on a common counterweight 7 to a fixed point. Where two towers are used in the same garage well, interlocking means is provided for the driving- gear to prevent collision, and also so that they can be operated as a unit when desired.

摘要： 15,611. McKenna, W. S., and Whiteley, H. Aug. 1. Annealing &c. furnaces ; charging and discharging.-Portions of the bed of a reverberatory or - other furnace for heating annealing-boxes, muffles, glass-melting pots, &c. are made removable on trucks which run on tracks in recesses 6. The movable bed-pieces 15 rest on ledges as shown, but are lifted for withdrawal, preferably by turning the eccentric axles of the trucks by means of worm gearing operated from outside the furnace. The trucks are withdrawn, leaving the bed-pieces in place. The gases from the furnaces 31, 31 pass through flues 34 into the recesses 6, and up through passages on each side of the movable bed-pieces. They leave the furnace by passages 39 and the flue 40. The trucks are run in and out by chain and sprocket gearing 27, thrown in and out of gear by suitable clutches. The furnace is specially applicable for annealing iron plates.
