Title: Improvements in coin inlet mechanism for use on prepayment meters for operation by coins of different values
IPC: G07F15/02
Filed: 1937-03-13
Abstract: 481,048. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. March 13, 1937, No. 7431. Convention date, Dec. 24, 1936. Addition. to 480,552. [Class 27] In prepayment meter mechanism as described in the parent Specification, the pins on the slide 11, which is set in position, according to the coin inserted, by a projection 13 engaging slots in the coin-actuated slide 5, transmit the rotation of the coin drum 3 to the quantity mechanism shaft 19 by means of at least two pinions 20, 21 positively connected to said shaft, one or both of the pinions being rotated through a greater or less angle, according to the size of the coin, during the rotation of the drum. The slide 5 has five slots 6, 7, 8, 9, 10 corresponding to a half-crown, penny, florin, shilling, and sixpence respectively, and the slide 11 has five sets of pins 14 ... 18. If a penny is used, the pin 14 rotates the pinion 20 through one tooth, but together with all the other pins misses the pinion 21. When a shilling is used, the pins 14, 15, 16, seven in number, rotate the pinion 20 through seven teeth, but only the pins 14, 15, five in number, rotate the pinion 21 through five teeth, so that the shaft 19 is turned an amount corresponding to twelve teeth, that is twelve times as much as it would be rotated for a penny. For a florin, the twelve pins 14 ... 17, and for a half-crown the fifteen pins 14 ... 18 actuate both the pinions 20, 21 thus rotating the shaft 19 an amount corresponding to twenty-four and thirty teeth respectively. If a sixpence is used, the pin 14 actuates both pinions, but the pins 15, four in number, actuate pinion 20 only, so turning shaft 19 through an amount equivalent to six teeth. In a modification, the pinions 20, 21 instead of being directly connected to the shaft 19 as shown, they are connected to it through an epicyclic gear, the planet wheel carrier arm of which is fixed to the shaft.

Filed: 1960-03-03
Abstract: 899,111. Aircraft undercarriages. CLEVELAND PNEUMATIC INDUSTRIES Inc. March 3, 1960, No. 7622/60. Class 4. [Also in Group XXXIV] A retractable leg 10 for an aircraft undercarriage carries lugs 12, 13 to which are pivotally attached beams 14, 17 each provided at its outer extremity with an axle 19 for a pair of landing wheels 21. The beams are connected to the leg 10 by spring loaded plunger units 22 and 23 respectively which permit upward pivotal movement of the beams but limit downward movement beyond a predetermined amount. Beam 14 carries a pair of lugs 42 and beam 17 a pair of lugs 36 and a rod 34 is pivotally attached at 37 to lugs 36 and at its other end passes through a one-way clamping device 38 pivotally attached at 41 to lugs 42. Device 38 comprises a housing 39 having a frusto-conical bore 44 into which frusto-conical clamping elements 46 are urged by a spring 51 so that rod 34 may move freely into the device but is prevented from being drawn out of it. A metallic spring 26 is connected at 27 to beam 14 and at 29 to a plunger 28 having a head 33 which slides within a bore 32 in beam 17 so that it permits free downward pivotal movement of the beams but limits upward movement to that resisted by spring 26. In operation light loads are resisted by spring 26 and extension of rod 34 operating within its elastic limit but high-impact loads are resisted by permanent tensile deformation of rod 34, which has to be renewed after each landing. An embodiment, Fig. 8 (not shown), is described for a leg having a pair of wheels on a single beam with plunger 28 operating within the base of leg 10 and rod 34 arranged vertically between the leg and a cantilever extension of the beam. A plurality of deformable tension elements may be provided to permit repeated landings, manually or automatically operated means being provided to render the clamping means to be sequentially rendered operative. The invention is particularly applicable to undercarriages on highspeed aircraft subject to kinetic heating liable to adversely affect hydraulic shock absorbers.

Title: Improvements in or relating to electric arc lamps
IPC: H05B31/00
Filed: 1925-03-24
Abstract: 252,495. Steinberg, E. March 24, 1925. Arc lamps. - In arc lamps for photographic, theatrical and like purposes with parallel carbons which are not fed forward as they burn, the carrier for the carbons is formed as a push-in device placed in the rear of the reflector from outside. The push-in device 4, Fig. 1, carrying holders 2 for the carbons 1 may carry a spring- actuated catch-lever 9 the free end of which engages a recess in a bearing-case 6 carried by the reflector 7. The carbons can thus be changed by withdrawing the device 4 from the reflector 7. The carbons 1 engage sockets in the holders 2 loosely and are held by screws, the holders 2 being carried by contact bolts 3 eccentric to the sockets for the carbons to permit adjustment of the distance between the carbons by rotation of the holders 2. In a modification, Fig. 3, the bolts 3 are provided with plugs 10 to receive sockets in a push-on contact block 11 carrying the leads. The push-in device 4 carrying the carbons 1 carries a catch comprising leaf-springs- 13 with detents which cannot be released fromrecesses in the bearing-case 6 until the block 11 is withdrawn, the extending ends of the springs- 13 resting on the sides of the block 11. The arc may be started by a hand-operated conductor- 21, Fig. 5, which can be brought into contact with the ends of the carbons. The conductor 21 may be pivoted at a point 22 outside the reflector- 7, being passed through a slot in the reflector 7 by means of an operating handle 23 and withdrawn back from the ignition position by a spring 24. The conductor 21 may close the slit in its normal withdrawn position and may be polished and shaped to conform to the reflector 7. The conductor 21 may be operated by a cord secured thereto and conducted over guide rollers. The conductor 21 may be triangular in crosssection with two contact-planes at an 'angle of 60‹ to contact with the carbons and may be of metal or hard carbon according as direct or alternating current is used. The conductor 21 may be directly formed with the handle 23 or may be mounted thereon on a resilient intermediate member such as a leaf-spring. Alternatively, the arc may be started by moving one carbon to bring it into contact with the other, one carbonholder 2<1>, Fig. 4, being pivotally mounted at 15 in the push-in carrier 14. The push-on contactblock may then be formed in two parts 11, 11<1>, a spring 19 on the reflector case 6 serving to move the carbon 1<1> in the holder 2<1> from the ignition position to the burning position. The arc may be enclosed in a closed glass bell mounted on the reflector so that the carbons can be removed without removing the bell; such a lamp placed above and away from a person with the carbons horizontal will illuminate nearly the whole of the person with highly actinic rays suitable for photographic purposes. Two or more arcs mav be arranged side-by-side or one above another in a common reflector casing.
