Title: Improvements in or relating to artificial hands
IPC: A61F2/58
Filed: 1931-02-07
Abstract: 370,553. Artificial hands. BLATCHFOR.D, C. D. W. and BLATCHFORD, W. A. D., 90, Clapham Road, Stockwell, London. Feb. 7, 1931, Nos. 3956 and 14054. [Class 81 (ii).] An artificial hand has the thumb mounted on a lever or the like fulcrumed on a member adapted to be rotated about an axis attached to the wrist plate so that the thumb may have various positions relative to the fingers, means to lock the lever carrying member relative to the axis, and a spring-pressed cam member adapted when in co-operation with a surface to lock the thumb automatically against outward movement, being provided. Pivoted fingers, locked against outward movement by spring-pressed cam members, may also be provided. To the wrist plate 1 of the hand 2 is fitted a pivot pin 3, having slidably mounted thereon a member 5 carrying a fulcrum 6 for a lever 7, pivoted at 8 to a thumb 9 normally drawn towards the fingers 4, for example by a spring 11. The lever 7 may be bifurcated and is fitted with a pin 12, moving in a slot 13 in the member 5, and a pivot pin 14 carrying a cam 15, with an extension 16 which seats a spring 17 projecting into the lever 7. The cam 15 and co-operating surface 18 are shaped so as normally to lock the lever 7 against outward movement. When the lever 16 is pressed, the thumb can be moved outwards, and is automatically locked when the lever is released. The slot 24 is closed by a slotted plate 25 carried by the member 5. The member 5 is formed with a flange 19 carrying a pin 20 which engages holes in the wrist plate 1. By raising the thumb and its associated parts rotation is possible, the spring 22 returning the member 5 when the thumb is released. In a modification, Fig. 4, a rod 27, apertured at 28 to slide on the pin 3, has a groove 29 into which the cam 15 is normally pressed. The member 5 is locked against rotation by a spring-pressed lever 31, fulcrumed at 32, which engages a toothed member 30 and is unlocked by means of a sliding plunger 33 having a wedge shaped end 34. The fingers may be fulcrumed, and each provided with a cam plate engaged by a cam fulcrumed in the palm of the hand, so that they are looked in their inward position. The cam 15 in any of these constructions may be moved to unlock the thumb or fingers by other means, for instance by a member having an inclined surface, similar to that for moving the lever 31 (Fig. 4). The operating member may be held, for example by a latch, leaving the fingers or thumb free to pivot or permitting slight frictional engagement. The fingers may be mounted on levers, operated as shown in Fig. 1 for the thumb. The cam 15, carried by the bifurcated lever 7 in Fig. 8, is operated by a transverse movable member 40 having a conical extension engaging the extension 16, and an operating knob which simultaneously engages a lever 47 and, through suitable connecting means, moves the lever 44 which normally engages a toothed member as shown in Fig. 4. By connecting the extensions of the cams for locking the fingers and thumb by Bowden wire mechanism, simultaneous operation is possible.

Title: A method and apparatus for winding web material
IPC: B65H19/30
Filed: 1961-02-03
Abstract: 944,996. Winding webs. M. GENNERICH, and A. WINDMOLLER, [trading as WINDMOLLER & HOLSCHER]. Feb. 3, 1961 [Feb. 18, 1960], No. 4110/61 Heading B6B. A method of winding a continuous web 2 into rolls which are driven peripherally includes winding a core by peripheral contact along a generator of the core which is offset contrary to the direction of its rotation from the generator at the bottom of the core and after the roll has reached a predetermined diameter winding at a second position in which the roll is driven by contact along a generator of the roll which is offset in the direction of rotation from the generator at the bottom of the roll. A winding core 48, Fig. 1, on a winding shaft 49 is driven by belt 42, 43 at the beginning of a winding operation. The shaft 49 is held between members 50, 51 and 52, 53. When a roll 11 reaches a predetermined size a limit switch 92 is actuated by blocks 13, 14, thereby causing actuation of levers 46, 47 by pistons 59, 60 which move to the Fig. 2 (not shown) position. The shaft 49 together with blocks 64, 65 drop on to a driven supporting roller 9, supported by pedestals 21, 22 while a knife 73 cuts the web 2. The core 48 previously coated with adhesive picks up the cut end and commences winding thereon. The completed roll 11 is removed from the machine after the drive to a driven supporting roller 10 has been stopped by actuation of an electromagnetic clutch (not shown) in the drive. The pedestals 21, 22, roller 9 and the roller 82 being wound are then moved into the position shown in Fig. 4 by rotation of lead screws 26, 27. Fig. 6 (not shown) engaging threaded bores 30, 31 in the pedestals to transfer the roll 82, Fig. 4, with blocks 64, 65 to frames 19, 20 such that the roll 82 is then wound by the roller 10. When the blocks 64, 65 completely engage guideways 17, 18 and the pedestals 21, 22 are returned to their starting position. The tension of web 2 may be controlled to control tightness of wound rolls by driving the rollers 9, 12 through friction clutches (not shown) which in non-slip engagement drive these rollers at a higher peripheral speed than a feed roller 6, Fig. 1. Alternatively, the clutches may be replaced by infinitely variable speed gearing. The knife 73 may be replaced by a heated rod or wire when winding synthetic thermoplastic material. Specification 797,527 is referred to.
