Title: Method of shaping a coiled rectilnear incandescent electric lamp filament
IPC: H01K3/04
Filed: 1956-10-18
Abstract: 800,929. Sharing filaments for electric lamps. ATELIERS DES LAMPES DE GENNEVILLIERS. Oct. 18, 1956 [Nov. 8, 1955], No. 31747/56. Class 39(2) [Also in Group XXII] Lamp filaments which are coiled into a single or multiple helix on a rectilinear axis, and from which the winding or supporting core has been removed, are shaped to an arcuate or other form by introducing a central wire or like body 9 axially into the helix, deforming the filament together with the introduced body 9 to give the filament the requisite shape, heating the filament assembly to a temperature sufficient to eliminate the stresses produced by the deformation, and finally removing the central body by chemical means. The invention is particularly applicable to helical filaments of arcuate form which are supported solely by their leading-in wires within bulbs for motor vehicle lamps. In the example, the end portion of a molybdenum wire 9 of a diameter slightly less than that of a single coiled helical filament is threaded through the helical filament 14 which has two parallel leading-in portions 3, 5 at rightangles to its axis. The wire 9 is unwound from a spool 10 by a gripping device 8 until its extremity meets a stop 1, the helix being located in a recess of arcuate section in a clamp 4. A former 16 of circular cross-section is pressed lightly against the middle of the helix. The length 13 of the wire 9 between the end stop 1 and a pair of co-operating shears 7, 12 is then severed by operation of the shears, and the protruding end portions of the severed wires are pressed downwardly by pushers 2 and 6 provided with grooved faces to receive the said ends, the pushers being moved along arcuate paths 17 and 15 respectively having their centre at the centre of the former 16. After bending the filament, together with the length of inserted wire, to the extent required the pushers and the former 16 are retracted, and the released filament is annealed at about 1250‹C. for ten minutes in a hydrogen atmosphere or in a mixture of 25 per cent hydrogen and 75 per cent nitrogen. The central body 13 may be removed by dipping the filament assembly in a hot bath of sulpho-nitric acid. The insertion of the central body into the helix and the shaping of the parts thus associated may be carried out on. separate machines.

Title: A coin freed apparatus for playing a game of skill
IPC: G07F17/32
Filed: 1929-10-19
Abstract: 341,544. Coin-freed amusement apparatus. CHUBBS AUTOMATIC MANUFACTURING CO., Ltd., South African Building, and PINDER, G., 25, Oakington Manor Drive, both in Wembley, Middlesex. Oct. 19, 1929, No. 31764. [Class 27.] Coin action, weigltt.-In a coin-freed amusement apparatus in which the coins inserted, less a percentage retained by the machine, are returned to the operator as prizes delivered at irregular intervals occurring in a definite repeated sequence, a momentary indication is given at each operation of the machine, such indication being varied at each successive operation according to a sequence which corresponds to the sequence of prize deliveries. Each coin inserted drops down a shoot 2, Fig. 2, to a sliding carrier 3 where it is supported by a pin 23 on a trip lever 22 having a depending pawl 24. In this position, it tilts a lever 7c which, through a rod 7b, releases a catch 7a retaining a lever 7. By rocking an outside handle on a shaft 13, an arm 14 engages a depending arm 15 on a slide 11 and moves this slide to rock the lever 7 on its pivot 8 against the action of a spring 9 which is connected to the slide 11 through a bell-crank lever 10. The lever 7 moves the carrier 3 across the machine behind a glass panel, a figure being attached to the carrier to draw attention to its movement. The carrier moves above a series of slots marked with the names of various " stocks " or " shares " and, during its return, the pawl 24 is tripped by one of a series of pins 25 projecting radially at different angles from a shaft 26. This releases the coin which drops through the slot of a particular " share " thereby giving a momentary indication, and falls down a shoot 5 to a rotary drum 6. A full stroke of the lever 7 is ensured by a pawl and rack 8c, 8a and its motion is regulated by a flier 21 geared to the shaft 20 of the bell-crank lever 10 so that the carrier is moved slowly. The drum is rotated step-by-step by a pawl 42 on the lever 7 engaging a star-wheel attached thereto. The drum is divided by radial partitions into compartments of different sizes, the contents of which are delivered through a slot in a cover plate 37a to a shoot 37 for return to the operator. One compartment is provided with a ledge 40 which prevents the coin therein from entering the shoot 37 but which allows it to pass to a second shoot 38 leading to the money-box. The number of teeth on the star-wheel is the same as the number of pins 25 on the shaft 26 which is rotated through bevel gearing from a vertical shaft 27. The shaft 27 carries a ratchet-wheel 28 which is rotated by a pawl on a slide 30 actuated by the lever 7. An indicating drum 46 on a shaft 45 geared to the shaft 26 is marked with the words " yes" and " no," to give an indication whether the next operation of the machine will result in the delivery of a prize or not.

Rotary tipplers.-Relates to tipplers of the type which are rotated by a friction wheel 3, and to means for starting the rotation automatically by the wagon entering the tippler and for stopping the tippler after each revolution. The tippler rests upon rollers 2 and is normally supported by a sliding or pivoted stop 16 resting upon a bracket 18 so that the rings do not engage the driving wheels. When a wagon enters the tippler, the front axle depresses a lever 8 and is stopped by the head 4<a> of a lever 4 pivoted at 5. The lever 8 is pivoted on the lever 4 at 7 and is connected by links and levers 9 - - 15a with the stops 16 which are pivoted on the tippler rings at 16a. The connections include toggle levers 15, 15<a>, with their pivots normallv in line, as shown, or cam mechanism may be provided in place of the toggles. When the lever 8 is depressed by the incoming wagon, the toggle levers 15, 15a are moved to the position shown in broken lines, the stop 16 is withdrawn, and the tippler rings rest upon the driving wheels 3. During the rotation of the tippler a cam 6 beneath the lever 4 is turned aside in known manner so that the stop 4<a> falls below the axle of the wagon, and a counterweight 17 or spring can then move the stop 16 outwards so as to re-engage the bracket 18 and stop the tippler. The cam 6 and lever 4 are re-set by the outgoing wagon.
