Title: Improvements in means for packing kinematograph films in light tight cases
IPC: G03B17/26
Filed: 1925-05-28
Abstract: 250,415. Newman, A. S. May 28, 1925. Kinematograph apparatus. - In a light-tight case for a roll of film, fitted with a pin or projection around which the roll is placed, means are provided for moving the pin &c. so as to press the film against the case to prevent unwinding during transport, and for moving it towards the centre of the roll to release the film for use. Fig. 1 shows a film case, having one side removed, and comprising compartments b c, blocks d d<1> round which the film passes, and exit and entrance channels f g. The film roll k is placed round a projection i on a rotatable plug h in one side of the case, the plug having a lever externally fixed to it so that the projection may occupy the position shown in full lines, to press the roll against the wall of the compartment, or may be turned to the position shown in broken lines to free the roll. The lever may be urged by a coiled spring or by a tensile spring against a stop retaining it in the position shown, and the end of the lever may project beyond the corner of the case to prevent the case from being placed in the camera with the lever in the position shown. In the alternative position, the lever may extend towards and not beyond the other upper corner of the case. In a modification, shown in section in Fig. 5, a pin p within the roll of film is carried by a slide c moving longitudinally within a groove s formed in the side and covered by a plate t. A projection q passes through a slot v in the plate t to engage a stop within the camera when the case is inserted therein, the slide o being then moved against the action of a spring in the groove s. According to the Provisional Specification, the plug h, in the construction shown in Fig. 1, may be provided with holes to receive a loose spanner.

Title: Improvements in looms for weaving terry or looped fabrics
IPC: D03D27/08
Filed: 1935-05-13
Abstract: 456,588. Terry looms ; tensioning and letting-off warps. FAUVARQUE & CIE, and CASTEELE, M. VAN DE, 16, Rue du Marechal Foch, Roubaix, France. May 13, 1935, No. 14047. [Class 142 (ii)] A Terry loom is provided with means for limiting the amount of warp to be drawn off the terry beam at each effective stroke of the lay and with means for varying the spacing of the loose picks from the fell of the fabric according to the tension of the terry warp. In the arrangement shown, excessive tension resulting from excessive consumption of terry warp displaces the back terry roller 10 and its supporting levers 11 thereby allowing a slide 13 to drop and impart a clockwise movement to a lever 16. The latter, acting through a rod 17 and lever 18, moves a pawl 20 towards the front of the loom and away from a pin 21 on toggle mechanism 22, 23, which connects the lay to the crank shaft, so as to delay the engagement of the pin 21 by the pawl 20 when the latter is raised by the action of a cam 36. The stroke of the lay is thus increased, the spacing of the wefts and the length of pin reduced and the roller 10 gradually repositioned. The means for limiting the warp let off during the weaving of terry comprises a free wheel device 34 connected to the take-up roller and to the roller 7 over which the terry warp passes. When a fabric without loops is to be woven, the cam operated lever 37 controlling the pawl 20 is disabled by a Jacquard controlled pawl 40, the slide 13 is held by a serrated block 15 and an upward movement of the roller 10 causes a brake 28 to be applied to the roller 7.

Title: Improved safety device for chain-driven apparatus
IPC: B66B29/00
Filed: 1931-05-12
Abstract: 378,859. Escalators. TILLY, G. H., 8, Fitzgerald Avenue, East Sheen, Surrey. May 12, 1931, No. 14089. [Class 78 (i).] In chain-driven apparatus such as escalators, the pins 1 connecting the links (not shown) of the chains are connected at their outer ends by members 4, 5 which become disengaged when a link stretches, or breaks, and thereupon move into a position in which they cause the operation of escalator stopping means and/or a signalling device. The free end of each member is provided with a slot 7 which engages a stud 6 on the adjacent member, the arrangement being such that the members disengage when the distance between the pins is increased by “ inch. When the members fall, they make contact with a live insulated metal track 8 connected to the secondary 9, Fig. 3, of a transformer 10, the primary 11 of which is connected to the supply mains 12. The secondary 9 is connected with a relay coil 13 which when energized operates an armature (not shown) to which is attached a contact strip 14 normally lying across terminals 15 in the main control circuit of the escalator. The winding 9 may alternatively, or in addition, be connected to a bell and/or lamp. The members 4, 5 may be moved out of alignment by springs. In a modification the live track is replaced by a chain which is so arranged that a fallen member will engage with it and cause it to move to give a signal, or actuate stop mechanism. In another modification an electrical device is actuated by the descent of a metal ball, or other loose member, which normally is held up by a safety member, or between two such members.

Patent GB-146790-A (GB)
Abstract: 146,790. Mays, J. F. April 10. 1919. Adding-apparatus.-Relates to key-set, keyoperated, multiple-bank machines having transfer and differential-actuating mechanism described respectively in Specifications 146,791 and 147,265, and consists in the provision of means whereby excess movement of the numeral drums of the totalizing-counter in relation to their actuators is prevented by bringing pawls carried by the driving-mechanism into locking engagement with toothed wheels on the drum shafts. This locking engagement occurs during an ineffective first movement of the keys and actuating-shafts which is allowed by lost-motion devices provided in the driving means for the drums. The differential, key-operated, spring-retracted, actuating shafts carry toothed sectors 43 engaging pinions 44 connected to disks 46 by pins 64, Figs. 2 and 6, thereon engaging slots 65 in the pinions, the pins 64 being connected by springs 62 to pins 63 on the pinions. Motion from the disks 46 is conveyed to the numeral drum 38 through pawls 47 engaging ratchet teeth 45 on the interior of the drums. The pinions 44 and disks 46 are carried by concentric sleeves 49, 48, which are loose on the drum shafts 39, and have secured thereto disks 52, 58. Formed in the disks 58 are slots 59 provided with cam-surfaces 61 adapted to depress, during the initial idle movement of the pinions 44, pawls 53, Figs. 4 and 5, pivoted to the disk 52, into engagement with the forward faces of the teeth 51 of wheels 50 secured to the shafts 39, the number of teeth corresponding to the numerals on the drums. Movement of the pawls 53 by the cam faces 61 is effected through pins 56 on the pawls extending through slots 57 in the disks 52. In operation, the first movement of the sectors 43 on the differential actuating shafts moves the pinions 44 to bring the further end of the slot 65 against the pins 64. During this movement the members 46 are held in the inoperative position against stops 67 by the initial tension of the springs 62, and the pawls 53 are brought in front of the teeth 51 by the cam surfaces 61, thus preventing the cliums from overrunning the members 46 and the pinions 44 when these are driven bv the sectors 43 on the continued downward movement of the keys.
