Title: Improvements in or relating to haul-off devices for wire or other filamentary material
Inventor: HINDS RONALD
IPC: B21C47/34
Filed: 1962-02-09
Abstract: 965, 808. Forwarding filaments. BRITISH INSULATED CALLENDER'S CABLES Ltd. Feb. 8, 1963 [Feb. 9, 1962], No. 5075/62. Heading D1D. A pull-off device for advancing wire or other filamentary material e.g. through a wire coating apparatus comprises a haul-off capstan between the supply and the take-up reels. The capstan comprises a spindle 2 drivable from a variable speed motor via a pulley 6, a grooved drum 11 which is rotatably mounted on the spindle 2 and carries a bevel gear 14, a second bevel gear 15 fixed on the shaft 2 and a cage 20, 21 which carries planet gears 23 engaging the bevel gears 14, 15 and has a rim 24, 25 with notches 26 thereon projecting beyond the drum 1; a manually operable, spring loaded crank 31 mounted on a spindle supporting plate 4 has a projection thereon which normally engages one of the grooves 26 in the rim 24, 25 and thus prevents rotation of the planet cage. In starting up, the projection on crank 31 is moved in top engagement with rim 24, 25 and the wire take up reel is driven through a slipping clutch to wind on the wire at a speed which increases from zero to operational speed, the drum 11 being similarly rotated by the wire. At the same time the motor which drives spindle 2 is switched on and thus the bevel gear 15 is driven, the bevels 14,15 thus rotate at different speeds (and in opposite directions) and the planet cage 21 rotates. When the forwarding speed of the wire reaches the desired value i.e. when the drum 11 rotates at the same speed as the spindle 2 the planet cage, no longer rotates and the projection on crank 31 is allowed to engage a groove in rim 24, 25 so that drum 11 is driven from the pulley 6. The rim 25 and the walls of the slots 26 are of contrasting colours so that it is easily seen when this rim ceases to rotate.

Abstract: 271,576. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Feb. 27, 1926. Manual and semi - automatic exchange systems, - In a trunking system in which main exchange trunks such as 4 are branched at a junction office D to a number of zone offices A, B, C, when one of the branch trunks is taken into use, all the remaining branch trunks are disconnected from the common trunk. When the operator at the zone office A takes into use the branch trunk 1, sleeve relay 11 energizes and lamp 10 lights, and bridge relay 12 is disconnected. Polarized relay 13 at the junction office D energizes. The polarized relays 13', 13" associated with the branch trunks 2, 3 do not operate since their windings are opposed. Relay 13 therefore connects up cut-off relays 18<1>, 18<11>, which disconnect the branch trunks 2, 3, and energize bridge relays 12<1>, 12<11> to mark them busy. Relay 25 energizes upon the reply of the called party, and bridges a coil 27 across the high resistance lower winding of relay 13. If all the common trunks are in use, ail the branch trunks at each zone office are marked busy, and a chain circuit 50 is completed from a busy interrupter 51 to the sleeve circuit of a particular branch trunk 1. Thus by testing the jack 7, the operator can determine whether or not there is a common trunk available. Fig. 2 shows an arrangement by which a lamp 101 is lighted to indicate the next available branch trunk, and the lighting circuit is transferred to the lamp of the next branch trunk when the preceding one is marked busy.

Abstract: 291,163. Jackson, L. Mellersh-, (American Encaustic Tiling Co., Ltd.). Feb. 28, 1927. Press cylinders; governing and controlling; producing part of stroke of by liquid at lower pressure than working liquid; ram retracting - devices; pressure-producing apparatus; working valves. - In a hydraulic press the operating - means comprises a closed hydraulic circuit under superatmospheric pressure, a pump being located in the circuit for generating high pressure during the working part of the stroke. The differential plunger I, H, G, Fig. 6, works in a cylinder having a partition 30 and a lower tapered portion. A small pump V draws liquid from a reservoir X containing liquid and compressed air, and delivers it to the port 3 of a valve casing T, and the cylinder space E is in continuous communication with the air space in the reservoir through a pipe 6. When a valve M is in the position shown in full lines, the cylinder spaces D, E, F are all subject to the reservoir pressure, a small volume of oil is delivered by the pump to the space D, and the plunger descends into contact with the work. The subsequent rise of pressure closes a valve 25 in the connection between the reservoir and space D, so that the whole of the pressure liquid supplied to that space comes from the pump. On the attainment of a predetermined pressure, a plunger 19, Fig. 7, in a cylinder 10 is moved against the action of a spring 18 to move a toggle 13, 14 past its central position; the motion of the toggle is continued by a spring and the valve M is thereby set in the position indicated by the dotted lines C. The pump then delivers into the space F, and the space D communicates with the reservoir, so that the plunger is retracted, until a push member 17 operated from the plunger acts on an arm 20 to move the valve into the neutral position B. A manually-operated rod 54 is provided for moving the valve out of the neutral position to initiate a new cycle, and a safety valve 9 is. disposed between the pipes 2 and 7.
