Abstract: 882,423. Tyre building machines. DUNLOP RUBBER CO. Ltd. March 14, 1958 [March 21, 1957], No. 8192/58. Class 144 (1). In building tyres on a cylindrical drum 1 the tread band 5 is applied to a carcase 4 on the drum by means of a cylindrical series of thin flexible plates 6, rotatably disposed coaxially with, and at each end of the drum 1 and of a diameter to first sleeve over the carcase 4 to leave a central gap A between the adjacent ends of the two series, the tread band being first wrapped on to the plates as they are rotated with the drum, and simultaneously being stitched to the carcase at the gap A by a pair of rollers 19, and the plates 6 and rollers 19 then being moved axially outwardly in unison to complete stitching of the tread to the carcase. As shown, the plates 6 are carried by rings 8, which are rotatably supported on rollers 9, carried by support rings 10. The rings 10 are movable axially of the drum by rack- and-pinion arrangements mounted in frames 13 and 17 respectively, the frame 13 supporting also the drum shaft 2 and the frame 17 being movable about a vertical pivot 18 to permit removal of the finished tyre. The plates 6 of each series may be disposed side by side as shown, or may overlap each other to provide a continuous cylindrical surface.

Abstract: 679,344. Seed sowers. MULHALL, D. April 9, 1951 [June 12, 1950] No. 8200/51. Class 6(i) A seed sower of the type comprising front and rear rollers 1, 5 with a seed hopper 9 supported on a framework 2 provided with guiding handles 7 and an attachment 6 for coupling to a horse, is characterized in that the discharge of seed from the hopper is controlled by a shutter valve operated at intervals by a tripping dog 28, adjustably mounted on a shaft 24, which co-operates with one of a series of concentrically arranged projections 19, 20 or 21 on a disc 18 mounted on a transverse shaft 12 driven by cranks 15, 16 and connecting rods 17 from the rear roller 5. The dog 28 is moved by engagement with the pins and opens a slide valve 57 simultaneously with a shutter 39 forming the outlet of a seed tube 38. A rotary agitater 14 is mounted on the shaft 12 and the shutter valve includes two adjustable plates 41, 42 the plate 41 being provided with a series of different sized holes which co-operate with a hole in the plate 42 to vary the effective diameter of the hopper outlet. The plates are adjusted by hand and clamped in position by means of a screw 55. Twin cutters 60 are provided to form a furrow for the seeds. The seed pipe 38 serves as a magazine for seed since the shutter 39 shuts before any particular seed discharge liberated by the shutter will have reached the bottom of the pipe 38.

Title: Improvements in or relating to the spindles of spinning, twisting or like frames
IPC: D01H7/04
Filed: 1926-03-29
Abstract: 274,929. Gaunt, J. S., and Dyson, H. March 29, 1926. Spindle apparatus.-In spinning, twisting, and like frames the spindles are mounted in a bolster b in an upper ball bearing d, comprising an annular race bounded below bv a bushing and above by an adjustable member adapted to engage closely around the spindle, and in a resilient footstep bearing that allows a slight gyratory movement of the spindle. The balls 6 are mounted between a bush 7 and a flange 8 depending from a cap m screwed on the top of the bolster and provided with lubricating holes 10. A felt or other washer n is fitted between the bolster and the cap, the edge of the bolster recess 13 being bevelled to facilitate the passage of lubricant to the balls. The footstep comprises a collar e and disc f which is allowed lateral play in the bolster, vertical displacement thereof being prevented by a shoulder 16. The portion of the spindle that carries the cop tube is tapered and the lower part 2 is parallel and of larger diameter, the bolster being restricted at 25 to prevent the removal of the spindle during doffing. The diameter of the lower part of the spindle is made in accordance with the counts to be spun. The bolster is cut away at 24 to accommodate the drag member which is carried on a weighted lever, the pivots of which extend through the bolster into a groove 30 in the plug p which supports the footstep.

Filed: 1947-04-02
Abstract: 623,465. Interconnected valves. ELLISON, Ltd., G., and CANTO, A. M. April 2, 1947, No. 8949. [Class 135] [Also in Group XXIV] The spindles 15, 19 of inlet and exhaust valves of hydraulic machines are interconnected by gearing 21, 22 or other interengaging members to be actuated simultaneously by a single lever 24 on one of the valves. A sliding rod 25 connected to the machine guard interlocks with a slot 27 in a boss 26 on one of the valves so that the machine cannot be operated until the guard is in its closed position and the guard cannot be opened whilst the machine is operating. The spindles 15, 19 have a slotted engagement with screwed members 13, 17 carrying valve members 7, 12 with a certain amount of lost-motion taken up by springs 16, 20. This ensures that either valve is fully closed before the other is opened. More than two valves may be interconnected when the fluid has to be controlled at different pressures or to different places on the machine. Other forms of interlock between the rod 25 and a rotatable boss or disc on one of the valves are described.

Abstract: 983,101. Transverse-flow fans. FIRTH CLEVELAND Ltd. March 13, 1961 [March 11, 1960], No. 9059/61. Heading F1C. [Also in Divisions F2 and H2] A fan unit comprises an electric motor supported by a base and surrounded by a casing, a cylindrical bladed rotor supported coaxially on the motor shaft in overhang relation to the motor, and guide means cooperating with the rotor to guide air twice through the rotor blades in a direction transverse to the rotor axis. Fig. 9 shows a fan supported by a ring 92 carried by a post 91. The guide means 99 rests on an extension 100 of the support ring 92 and is held in place by lugs 100a interengaging with the extension; it can be removed by merely lifting it off the extension. The motor housing 94 can be pulled off a flange 93 against the frictional restraint of resilient projections 93a. The impeller 96 may be made detachable from the shaft, as by providing a screw-threaded engagement between the impeller and the shaft. Alternatively, the impeller can be pulled off a cylindrical boss 33, Fig. 3b, at the end of the shaft, against the restraint of spring-loaded detent balls 34 engaging an annular groove 11b in the impeller end disc 11<SP>11</SP>. The balls 34 may be replaced by a toroidally wound resilient strip located in a peripheral groove in the cylindrical boss. As a further alternative, the impeller end ring 83, Fig. 8, is bevelled at 83a to snap over a similarly bevelled disc 85 carried by the shaft, the impeller and the disc 85 both being of resilient plastics material. A similar arrangement may be used for attaching an end disc 82 to the impeller. In the fan shown in Fig. 4, the impeller end disc 51 is held by magnetic attraction to a disc 47 carried by the shaft. A centering projection 48 engages a recess 52. The discs 47 and 51 are magnetized with annular or sectional zones alternating in polarity. In a modification, the end disc 51 is of ferromagnetic material and the disc 47 is formed as a magnetized cylindrical block associated with a magnetic disc having an axially-directed peripheral flange which abuts the end disc 51. In a fan comprising an impeller at each end of the motor shaft, the guide means for the two impellers are formed as a single unit secured to the motor casing by a milledhead screw. Specification 876,611 is referred to.

[Class 100 (iii)] Keyboards.-In keyboard mechanism of the kind comprising power-driven cam-yokes each of which is normally held in inactive position by a trigger actuable by a keylever, auxiliary means carried by the trigger are provided for arresting the cam-yoke at the end of a cycle in case the trigger fails to return to normal position for the purpose. The trigger J is recessed to accommodate a dog J<2>, which is pivoted thereto and is capable of slight relative movement, limited by a pin J<5> passing through a hole of larger diameter. The upper end of the dog is pressed away from the trigger by a spring J<8>, and, when the trigger is rocked to release the cam-yoke, the dog is caused to yield by a cross-piece F<5> on the yoke. If, when the yoke is raised by the cam, the trigger has not returned to normal position, the dog snaps under the cross-piece F<5> and maintains the yoke in raised position.
