摘要： 434,142. Kinematograph apparatus. MAYTUM, J. A., 34, Foreign Street, Camberwell, London, SMITH, L., Belgrano, Burton Joyce, Nottingham, and HANSEL, C. W., 142, Bromham Road, Bedford. April 18, 1934, No. 11623. [Class 97 (i)] The driving train to the shuttei includes a coupling permitting the shutter to be put out of use when the apparatus is used as a projector. As shown, a wheel 1 in the driving train meshes with a pinion 2 slidable on, and rotatable with, the shaft 3 of a drum shutter 9. The elements 7, 8 of a dog clutch are carried by the pinion and shutter, and a grooved collar 5 and pivoted fork 6 permit the clutch to be engaged when the apparatus is used as a camera, and to be disengaged when it is used as a projector.

摘要： 364,907. Spring suspensions. FLEXION PRODUCTS, Ltd. and SMITH, L., The Hyde, Hendon, London. Feb. 19, 1931, Nos. 5231, 9483, and 12650. [Class 108 (ii).] In vehicles having two parallel axles, two springs on the same side of the vehicle are interconnected by equalizing mechanism which includes a lever fulcrumed on the frame and connected to the springs at points situated on the same side of its fulcrum. In the construction shown in the Figure, the two springs 14, 15, one for each axle, are pivoted at their forward ends 31, 32 to the vehicle frame or to a bracket 30. The rearward ends are connected by linkwork to two points 28, 117 on one side of the sliding fulcrum 21 of a lever 20. The rear spring 15 is connected to the point 28 by a simple link 26, while the front spring 14 is connected to the point 117 through a rocking lever 16. Lateral movement of the rocking lever is prevented by curved guides 37 on the side frames. In a modification the sliding fulcrum 21 is replaced by a pivot and a short link connects the adjacent ends of the equalizing lever 20 and the rocking lever.

摘要： 301,606. Morton, C. R., Robertson, N. D. G., and Smith, L., (trading as Wayne Electrical Co.). Oct. 21, 1927. Apparatus for automatically taking up slack of conductors, of the type described in Specification 184,518, in which swivelling arms support a spring-controlled cable reel D, one arm being fitted with a gravity catch to retain the reel D with the cable extended, is now formed with a second gravity catch pivoted to work in the opposite direction to prevent the cable continuing to pay out when the lamp supported is of weight greater than the strength of the spring. In the embodiment a bracket A carries a swivel B with arms C, C which support a spring controlled reel D. The arm C is fitted with a catch E to retain the cable extended against the spring action. The catch E is pivoted on a pin e passing through a projection c on the arm C, a finger e engaging a recess in a recess c in a projection c . When the catch E is operative, a projection e on the face d of the reel D is held in a recess e in the catch E. A second catch F, pivotally mounted on a pin c carried by a projection c of the leg C', is adapted to engage pins f on the face d of the reel D. A finger f on the catch F engages a recess c in a projection c of the arm c .

摘要： 260,169. Smith, C. H., and Smith, L., (trading as Smith, C. H., & L. 0.), and Sinclair, J. April 27, 1926. Driving auxiliary parfs or external machines.-In an auxiliary casing 9 attached to the main gear-box 1 motion is transmitted from the main driving-shaft 6 to a shaft 18 driving an auxiliary machine through one or more gear-wheels 15 intermediate the driving and driven gearwheels 14, 17. The shaft 18 is actuated from the gear-wheel 17 through a handoperated clutch 21 and may carry a pulley driving a fan, pump, dynamo or other machine. The casing 9 comprises a plate 3, a flanged or hollowed part 10. and a cover or covers 11, 12, all bolted together. The central part 10 may be formed in one with either of the other parts 3, 11. The plate 3 is bolted to the engine end of the gear-box 1 after the usual cover plate of the bearing 2 has been removed, and both plates 3, 11 are formed with lugs which rest on the sub-frame supporting the gear-box. Lubricant from the gear-box passes into the auxiliary casing.

摘要： 657.569. Draught-excluders. ATOMIC CARPET & UPHOLSTERY CLEANERS, Ltd., (trading as ATOMIC DRAUGHT SEALING CO.), and SMITH, M. L. Dec. 1, 1948, No. 31124. [Class 20(iii)] A draught excluding joint for a door or window is made by nailling or screwing a substantially flat elastic metal. strip along one of its edges to one of the joint surfaces and then throwing up the free edge of the strip so that it bears with resilient pressure against the co-operating joint surface. The strip, which can be rolled up for transport or storage, is preferably made of phosphor-bronze about eight-thousandths of an inch thick and is formed with doubled over edges 1 and 2. A row of nail holes is punched near the edge 1 and the strip is creased longitudinally at 4. The strip is nailed to the door jamb or window frame and set up by running a hand tool 5. provided with a V-edged pressure roller 6, along the crease 4. Specification 434,291 is referred to.

摘要： 471,893. Kinematograph apparatus. MAYTUM, J. A., and SMITH, L. Feb. 11, 1936, No. 4157. [Class 97 (i)] A beater feed mechanism is operated by a crank cam or the like 9 located between the beater 13, Fig. 1, and a pivoted arm 11 bearing a shutter 12, the crank &c. being connected to the beater and the shutter arm by links 19 and 18 respectively so that rotation of the crank oscillates both shutter and beater. The film 2, fed by a sprocket 3, is pulled intermittently through the gate 4 by the beater 13, which is preferably in the form of a segment of a cycloid, and passes over a take-up sprocket 4 rotating on the same axis as the beater. The driven shaft 8 of the crank 9 is coupled to the sprocket 5 by a six-to-one reduction gear, and each of the sprockets 3 and 5 has a circumference equal to the length of six pictures so that the film is advanced by one step for each complete turn of the crank 9. The gate 4, Fig. 5, has an aperture a, and a pressure plate 22 carrying pins 23 and pressed against a front plate 26 by springs 28.
