Title: Improvements in coin testing devices
IPC: H05B1/02
Filed: 1934-09-13
Abstract: 440,672. Testing coins. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., East Street, Bedminster, Bristol, and HASTED, H. C., 32, Paddock Road, Cricklewood, London. Sept. 13, 1934, Nos. 26258 and 34546. [Class 27] A coin-testing device which rejects coins without a rim and those that are thicker inside the rim than a genuine coin comprises a carrier 2, Fig. 1, pivoted on stub axles 3 and provided with an adjustable counterweight 11 which holds an angle extension 13 against a fixed stop 14. The front of the carrier is provided with a pair of arms 5, 6 forming a pocket to receive a coin 8 from a sloping guideway 1. The arm 6 is slotted to form two bars 15, 16, Fig. 4, between which is pivoted on a pin 17, a three-armed feeler 18 having a pointed detector arm 21, an operating arm 19 and a counterweight arm 20. Also pivoted in the arm 6 behind the ears 15, 16 are two bent wires 23, 24, formed with gauging points 28, medial portions 25 passing through holes in the arm 6, and tail portions 26 bent at right angles to the parts 25. The arm 19 of the feeler normally enters between the tails 26 and holds the points 28 a distance apart equal to the thickness of a genuine coin but narrower than the width of the rim. In use, a coin passing from the position 35 in the guideway 1 to the position 8 in the carrier strikes the nose 21 of the feeler which it momentarilv rotates to withdraw the arm 19 and allow the rim of the coin to pass between the gauging points. The arm 19 is returned by the counterweight 20 to close the points 28. The carrier turns under the weight of the coin and, if the coin is genuine and has got a rim, it is held by the points 28 until the arm 20 meets a fixed stop, whereupon the arm 19 is moved from between the tails 26 and the points open to allow the coin to drop into a passageway for genuine coins. If the rim is too thin, the coin, during the movement of the carrier, will drop out to a passageway for rejected coins. If the coin is too thick, the arm 19 will be unable to enter between the tails 26, to close the points 28, and such coins will also not be retained in the carrier. A wire 45 prevents coins from leaving the guideway 1 while the carrier 2 is tipping. The frame in which the carrier is. mounted may itself be mounted so as to be rocked about an axis CD, to discharge any coin that may have jammed in the carrier. The rocking is effected by pushing a button or opening a drawer or the like.

Title: Cable control device
IPC: B64C13/30
Filed: 1971-04-19
Abstract: 1345918 Retracting aircraft undercarriages SOC NATIONALE INDUSTRIELLE AEROSPATIALE 19 April 1971 [7 April 1970] 26335/71 Heading B7G [Also in Division F2] An hydraulic selector D, Fig. 1, operable on an aircraft undercarriage, is actuated for lowering by a cable 4b from a pilot's control member A through a cable control device B and crank C. Cable 4a is the return cable. The cable control device includes a rotary member 3, Fig. 2, to which the cables are anchored at 5b, 5a, respectively. Cable 4b passes partly around a tensioning pulley 20 urged to the left by a tension spring 22 acting on a two-part lever 14 of which part 14b is integral with lever 17 (carrying pulley 20); lever part 14a carries a toothed detent 10, 11, which only just engages, in the rest position of Fig. 2, teeth on a ratchet wheel 9 secured to rotary member 3. In operation, when cable 4b is pulled to rotate member 3 counter-clockwise, the sideways force thereby exerted on pulley 20 pivots levers 17, 14, about 16 to raise detent 10 clear of ratchet wheel 9 to permit rotation. When cable 4a is pulled to rotate member 3 clockwise, the member rotates, during which rotation the teeth on ratchet wheel 9 successively escape from detent 10, which remains in contact with wheel 9. If the return cable 4a breaks in the absence of any positive actuating action at the pilot's station, cable 4b slackens, but the influence of spring 22 on lever 14 keeps tooth 11 of detent 10 engaged in the teeth of ratchet wheel 9, so rotation of member 3 is prevented and, in consequence, possibly-dangerous lowering of the undercarriage. A supplementary friction brake is applied at all times to the ratchet wheel 9 secured to member 3 (see Division F2).
