Patent GB-637224-A (GB)
Title: Improvements in rotary driving apparatus suitable for the drive of magnetic cyclometer registers
IPC: G06M1/14
Filed: 1946-02-15
Abstract: 637,224. Counting-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 15, 1946, No. 4763. Convention date, Feb. 24, 1945. [Class 106 (i)] [Also in Groups XXIV and XXXV] Apparatus for converting continuous rotary motion into an intermittent stepping rotary motion comprises driving and driven rotary members having the same axis of rotation, a lost-motion driving connection and magnetic means having a restraining or advancing force in excess of the driving member for a fraction of a revolution, this magnetic force being overcome when the driven member is driven directly by the driving member. As shown, a drum 1 and a double arm part 3 are secured to a shaft 2. A crank 6 of the arm 3 carries a piece of magnetic material 8 and extends into a forked portion of a wheel 5 secured to a gearwheel 4 pivoted on the shaft 2. The gear-wheel 4 is driven by an integrating device. When the wheel 5 is rotated the arm 3 is driven by a tensioned connecting spring 7 until the magnetic material 8 comes under the influence of a magnet 9. The arm 3 is held until the second prong of the wheel 5 drives the arm 6 forwards out of the influence of the magnet when the tension in the spring brings it rapidly to its former position, the number in the viewing position of the drum changing from 9-0. In a modification, the spring 7 may be omitted, in which case the crank arm 6 will normally rest against the trailing edge of the fork and the stepping action takes place when the magnetic material is attracted by the magnet 9. In a cyclometer the other end of the arm 3 has a driving pole tooth 10 of magnetic material. This tooth passes sufficiently close to a second wheel 11 with ten magnetic teeth so polarized that the wheel is driven 1/10th revolution. This 1/10th revolution when the wheel is driven is the 1/10th revolution of the arm 3 when it snaps forward. To keep the wheel 11 locked when it is not being driven, magnetic locking teeth 12 are provided. The shaft 13 of the second wheel 11 is also provided with an arm 14 with a magnetic driving tooth 10 to drive an additional wheel. In a modification, the magnetic driving tooth 10 is replaced by a permanent magnet 21 having a long polepiece 22 and a short polepiece 23 and the locking magnet 12 is replaced by a tooth 20. The magnet 21 is so magnetized that the short polepiece 23 neutralizes the holding action of the tooth 20 when the wheel is being rotated. Other positions for holding and neutralizing magnets are described.

Title: Improvements in or relating to thread-hammering machines
IPC: B21K1/56
Filed: 1953-02-20
Abstract: 730,325. Forging screw threads. TRURNIT, W., [trading as TRURNIT, F.]. Feb. 20, 1953 [Feb. 21, 1952], No. 4855/53. Class 83 (4). A thread hammering machine comprises a rotary head 7 carrying radially movable die hammers 5 which are actuated by rollers 3 through outer striking hammers 4 radially guided in a rotary ring 8 surrounding the head, the ring being positively driven from a driveshaft 11, Fig. 2, and the head being driven from the shaft through a resilient connection which, upon a braking action being applied to the head, permits the latter to have a limited angular movement relative to the ring, thereby causing the. striking hammers to move out of engagement with the die hammers. Intermediate members 6 may be provided between the die hammers and striking hammers and the radial movements of the latter are limited by bolts 9 which project with clearance into transverse grooves 10 of the striking hammers. The upper striking hammer 4<SP>1</SP> and die hammer 5<SP>1</SP> are fixed in their inner positions since the latter forms an anvil die for the other die hammers. The drive shaft 11, which carries a fly-wheel 53 and is driven through a flexible coupling 14, has an enlarged portion 15 within which the head 7 is rotatably mounted on bearings 16, 17. The head 7 has secured thereto a brake drum 20 carrying pins 26 which engage within transverse grooves 25 in sleeves 22, Fig. 3, guided in the shaft portion 15. The sleeves 22 are biased against stop-pins 24 by springs 21 and these springs effect the drive between the shaft and the head 7. The ring 8 is driven by pins 18 secured to the shaft portion 15 and passing through elongated slots 35 in the brake drum, which slots limit the relative angular movement between the head 7 and the ring 8. The drum is braked by a pair of brake shoes 26, 27 pivoted at 28, 29 respectively and actuated by pins 33, 32 projecting from a control shaft 34, Fig. 2. A screw blank, having a short starting thread formed at the end thereof, is inserted into a guide 38 mounted on the head 7.. The starting thread on the blank is first engaged by a radially slidable locking element 39 biased inwardly by a spring 40, which at its inner end is formed with a thread of the same pitch as the threads on the die hammers. The locking element which rotates around the stationary blank thus feeds the latter into the die hammers. At the end of the threading operation, the brake is actuated whereby the die hammers 5 are disengaged and open under centrifugal force thus releasing the screw. Simultaneously the locking element is lifted thereby permitting the screw to be withdrawn. The rotating assembly is mounted in a stationary housing 1 which seats within a rubber mounting in the threading machine.

[Also in Division B8] So that all cigarettes Z 1  and Z 2  (Fig. 5) produced from double length assemblies may have tips or mouthpieces similarly directed, the cigarettes Z 1  in holders 202 are turned end for end by guide means 212, 213 which lift, support and tilt one end of each cigarette while its other end is supported in the region of the holders 202 in a turning plane terminating at the holders 202. Double length mouthpiece cigarette assemblies are bisected on a cutting drum 222 by a circular cutter 225 and fed into alternate holders 202, of which there is an odd number, on a drum 201 where they are retained by guides 227, 228 and 229. The guides 228 are sufficiently spaced apart to allow short or filterless cigarettes to fall away while retaining normal cigarettes. The centre of each holder 202 embodies a recess 204 with arcuate opposed flanks 205 and 206. A guide 211 presses the inward facing ends of the cigarettes Z 1  down into the recesses 204 as the guide 212 starts to raise the other end. After the cigarettes Z 1  have been completely turned they pass under a guide 233 and are joined as they pass the bottom end of it by the cigarettes Z 2  which fill the empty alternate holders 202. The combined rows of cigarettes Z 1  and Z 2  then pass on to be discharged on to a conveyer 231. In another embodiment, Fig. 7, the cigarettes Z 1  are turned by means of a guide 118 assisted by suction and air pressure supplied through ducts 104 in holders 102. As the cigarettes Zi travel through sections D, E and F suction and air pressure are applied through the ducts 104 as indicated by the vertical arrows in Fig. 14 for section D, Fig. 16 for section E and Fig. 17 for section F. The air pressure applied during the passage through section F ejects short or other faulty cigarettes that have been left unturned, on to a plate 112. In yet another embodiment the cigarettes Z 1  are turned solely by pneumatic means.
