Abstract: 1,253,869. Tyre building drums. NATIONALSTANDARD CO. 12 June, 1969 [12 June, 1968], No. 29946/69. Heading B7C. A tyre building drum comprises sections 32 of interleaved support members 33 movable radially between inner and outer positions to form support surfaces of different diameters, and end assemblies 16 mounted in fixed axial relation to sections 32 and each having an outer surface which defines with the members 33 in their inner positions, a substantially cylindrical surface to support a tubular cylinder of carcass material, each end assembly including bead locating shoulder 90 displaceable radially by air bag 80, and a bead setting device 160 for applying beads against the shoulders. After applying successive carcass plies to said cylindrical surface, bags 80 are inflated to move shoulders 90 and devices 160 carrying bead rings move and hold the rings against said shoulders. Inflatable bags 64 are then partly inflated to wrap the carcass ply or plies partly around the bead rings whilst they are held by devices 160. Thereafter, as bags 64 are further inflated, these devices are removed from the bead rings and moved axially toward each other to cause the bags 64 to complete the turn-up. Members 33 are next moved radially outwardly whilst the beads are initially held by the shoulders to stretch the sidewall regions of the carcass. The carcass bead regions are subsequently released by deflating bags 80, and move axially towards each other as the outward movement of members 33 is completed, shaping the carcass to receive tread components. Chafer strips and sidewall rubbers are applied before moving members 33.

An emergency radio equipment for aircraft comprises means for transmitting a radio distress call in response to the operation of means actuated by the occurence of acceleration and/or rate of loss of height exceeding a predetermined value. An accelerometer switch comprises a conductive ball 1 suspended at the centre of a spherical contact 2 by a spring arrangement 3, contact being made between ball 1 and contact 2 when a given acceleration occurs in any direction. In parallel with this switch is a glass tube 4 containing mercury 5 which bridges contacts 6, 7 when the rate of charge of atmospheric pressure outside the aircraft exceeds a given value. Operation of either switch actuates a self-maintaining relay 12, master switch 11 being normally closed, and contacts 14 complete the circuit of a motor 15 which drives a magnetic tape 16 on which a distress signal is recorded. The recorded signal is picked up by a head 17 and modulates the transmitter 18. A lamp 19 indicates when the equipment is working. Further information e.g. position and course may be recorded on tape 16 at desired intervals, previously recorded information being erased, Fig. 2 (not shown).

Title: Improvements in cigarette collecting mechanisms for delivering cigarettes from cigarette making machines
IPC: A24C5/14
Filed: 1929-10-03
Abstract: 337,161. Triggs, W. W., (American Machine & Foundry Co.). Oct. 3, 1929. Cigarette-making machines. - In a continuous-rod machine in which the cigarettes are delivered into the axial pockets of a drum 31 rotating about a shaft 38 parallel to the cigarette rod and are delivered from the drum to a conveyer, the drum 31 is positioned to bring the axial pockets successively into axial alignment with the cigarette rod, and is provided with devices in the pockets for stopping the lengthwise movement of the cigarettes and with a device for aligning the cigarettes within the pockets. As shown in Figs. 1 and 4, the cigarettes are received from the guide tube 10 between grooved belts 11, 12 running over pulleys 13, 15 driven by means of a belt 23 and gears 25, 26. The drum 31 is driven from a shaft 42 by bevel gearing 41, 40 and is provided with axial pockets formed by trough-shaped slides 29 movable in slots 30 in alignment with short guide walls 32 at the receiving end. Each pocket is provided with a weak leaf spring 33 for gently stopping the entering cigarette, and the cigarettes are aligned in the pockets by a stationary guide 34 extending from the cigarette receiving position to the delivery position. The guide 34 is secured to a guard 36 encircling the greater part of the drum and carried by a bracket 37. Each slide 29 is mounted on a block 45 having a roller 46 engaging a stationary cam track 44 in order to move the slide axially on the drum, and lugs 47 in the path of the springs 33 press the springs out of engagement with the cigarettes, and serve also to limit the axial movement of the cigarettes in the slides. The released cigarettes are delivered upon a belt 48 running over pulleys 49. To enable defective cigarettes to be diverted from the drum 31 when starting and stopping the machine, the frame 21 carrying the belt pulleys 13 - - 16 is pivoted on the shaft 19 and provided with an arm 52 on which is pivoted a latch 53 normally held by a spring 54 in engagement with an abutment 55. When the machine is stopped, a rod 56 connected to the clutch lever pushes the latch 53 off the abutment 55 and allows the spring 54 to tilt the frame 21 and divert the cigarettes above the guard 36. When the machine has been re-started, the frame 21 can be brought into normal position by means of a handle 60. In a modification, Fig. 6, the drum 31 is provided with equally spaced division walls 61 mounted on separate blocks 62 each having a cam roller in engagement with a stationary cam 64. Radial pins 65 are arranged to engage the springs 33 and to limit the,longitudinal movement of the cigarettes in the pockets.

Abstract: 1473564 Abrasion belt machines DYNABRADE Inc 8 July 1974 [12 Oct 1973] 30060/74' Heading B3D A hand grinding device comprises an endless abrasive belt 18 extending about an idler pulley 30 on the end of an arm 22 mounted by a pivot 24 on a crossing 10, a driving pulley 16 which is driven by a motor 12 on the casing and has its axis extending longitudinally of the arm, and a pair of direction change pulleys 32, 33, the axes of which extend transverse to the arm, the arm 22 having relatively tiltable first and second parts 22a, 22b adjustable to control the tracking of the belt. The motor may be electrical or pneumatic and is mounted on the casing so that the axis of its drive pulley 16 is parallel to the arm 22 which is mounted by the pivot 24 in a slot 20 in the casing. The arm is spring urged about the pivot to effect tensioning of the abrasive belt and can be moved against the spring pressure by operation of a thumb press lever 26 for removal and replacement of the belt. The direction change pulleys 32, 33 are mounted on the part 22a of the arm for rotation about an axis perpendicular to the axis of pulley 16. The part 22a of the arm is mounted on the pivot 24 and formed with a recess 40 which receives the end of the part 22b of the arm, the parts being shaped for relative pivoted movement about a rib 48. A spring 42 urges the second part in one direction relative to the first to a position determined by a screw 44, the position controlling the belt so that it is under essentially uniform tension and tracks on the idler pulley 30.

Abstract: 161,227. Chamberlain, Ltd., E. A., and Vick, E. Dec. 3, 1919. Gearing for stopping and starting machinery.- In clutch and brake gear for one-revolution stamping-presses, a rod H operated by an adjustable eccentric h<2> on the main machine shaft 4 has a lug h' normally engaging a catch-lever J pivoted on a lever K secured on a rock-shaft 11, which actuates the clutch S through levers L and rods M engaging freely in holes in plates m<1> and carrying springs m<3>, and through bell-crank levers 14, and a rod 17. The shaft 11 actuates the brake 8, pivoted on a pin 26. through a lever arm 24 bearing on an adjustable screw 25 in the brake shoe. The operating-pedal A is carried by levers B on a rock-shaft C carrying a lever F supporting a hook G which, on depression of the pedal, releases the lever J from the lug h' so that the parts K, L, &c. fall by gravity and the clutch and brake are both positively actuated to start the machine. During rotation of the shaft 4 the lug h<1> re-engages the lever J and the driving- power applies the brake and disengages the clutch, the latter elastically through the springs m<3>. A cam 21 moving with the stamp head 13 bears on a roller 22 on the clutch-rod 17 to prevent premature clutch disengagement.
