Title: Improvements in vending machines
IPC: G07F11/14
Filed: 1919-06-10
Abstract: 137,476. Tintera, W. J., and Tintera, E. June 10, 1919. Delivery of articles stored in piles. -Articles are stacked in a pile on a support which is moved upwards step by step by the operation of a coinfreed slide, the topmost article being projected into a delivery shoot by a spring. The moving support 2 slides on a guide 1 and has spring dogs 6, 7 which engage respectively a rack 4x on a vertically reciprocable member 4 and a fixed rack g, so that by reciprocation of the rack 4<x> through the space of one tooth, the stack of articles is correspondingly raised. A wall 10 abuts against the stack on one side, and a spring 11 mounted adjacent to the top of the rack on the other side is compressed by the topmost article as it is raised and forces the article over the top of the wall as soon as the article is above the wall and down a shoot to an outlet 18. The shoot is formed with a curved outer portion m, n as shown, so that the articles are frictionally held. Coin action, mechanical-connexion.-The rack 4<x> is reciprocated by the reciprocation of a slide B in which is a pin 12 engaging an inclined slot 5<x> in the rack. The slide B is coupled to a slide C manually operated by a finger-piece C<x>, by a coin which rests against lugs 16, 17 after introduction through a slot 13 and, when in this position, is engaged by a finger 20 on the slide C and thus moved with the latter. When the fingerpiece is released, the slides are returned by a spring, and, the pressure on the coin being released, it will drop past a ledge 22 and lug 21<x> on which it originally rested, and into the coin receptacle. The insertion of a coin into the apparatus when empty is prevented by the engagement of a stop 5 on the rack 4<x> with the support 2, which keeps the slide, after its last operation, from moving back to the right, and thus closes the coin slot. Testing coins.-Operation by improper coins is prevented, in the case of washers, by the passage of the finger 20 into the hole in the washer, the consequent lost motion of the slide B prevents the making of a full stroke. A strip of tin &c. which is passed down below the normal level of a coin engages a stop N on motion of the slide, and when a slug of too great a diameter is inserted, it engages a stop M, in each case preventing motion of the slide B. A slug of substantially less thickness, but of the same diameter, as the coin fails to be supported by the narrow lug 21<x>, but drops into the coin receptacle.

Filed: 1956-05-11
Abstract: 800,124. Generating combustion products under pressure. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 11, 1956 [May 13, 1955], No. 14757/56. Class 51 (1). In a combustion chamber in which a gaseous flame stabilizing baffle is produced by injecting an auxiliary gas under pressure into the main gas stream through nozzles directed transversely to the main gas stream, the nozzles are inclined at different angles to the main gas stream in order to reduce or eliminate vibrations resulting from the combustion, some of the nozzles being inclined upstream and some of the nozzles being inclined downstream with respect to the main gas stream. In the reheat combustion chamber of a jet propulsion engine shown in Fig. 1, air under pressure, for example from the compressor of the engine, is injected through nozzles formed in two planes 4a, 4b in the turbine fairing cone 1. The nozzles are directed at different inclinations so that the frusto-conical surfaces forming the flame stabilizing baffles are inclined in opposite directions. In another embodiment the nozzles are formed in one plane only but adjacent nozzles are directed in different directions. Thus one nozzle may be inclined upstream, the next directed radially outwardly and the next inclined downstream and so on round the periphery of the fairing cone. The air used to form the stabilizing baffle may be caused to flow adjacent the inner surface of the fairing cone before discharge, thereby having a cooling effect on the cone. Fuel may be supplied to the air forming the stabilizing baffle. Specification 751,013 is referred to.

Abstract: 200,316. Hooydonk, A. C. van. May 31, 1922. Releasing-devices and controlling- arrangements for collectors.-A spring latch-device for releasing the tension of the springs upon excessive upward movement of the trolly pole 33 comprises a slidable latch-bar 68 adapted to release a bar 61 from engagement with a toothed member 54 pivotally connected by a rod 57 with the plunger 45 which carries one end of the springs 50. The outer end of the plunger 45 has an extension 47 which receives a sleeve 48 forming part of the spring yoke 49. The other ends of the springs are connected to discs 51 mounted on studs 52 carried by arms 37 which are connected to the trolly pole yoke 30 by studs 38 out of line with the studs 52 so that the arms 37 constantly tend to press against a screw 88 carried by the yoke. The yoke also carries a screw 73 which, when the trolly leaves the wire, engages the head 72 of the latch-bar bar 68 so as to release the yoke 49. The member 54 is secured upon a shaft 53 which has a second toothed member 84 engaged by a dog 83 carried by a frame 75 which is connected by a rod 77 to a lever 80 extending into the path of a lug 81 carried by the trolly pole, so that the springs 50 can be reset and the member 54 advanced toothby-tooth under the bar 61 by depressing the pole. The lever 80 is secured together with a lever 90 upon the pin 28, which carries the pole 33, so that when the pole is released and in falling rocks the lever 80, the lever 90 is also moved to allow a pivoted arm 91 to swing over and lock it, thus preventing the pole from rebounding. At the same time, the member 54 rotates and engages a pin 107 carried at one end of a lever 105 so as to force a pin 106 carried at the other end against the bearing-base 10, and prevent rotation of the pole, The arm 91 is withdrawn from the lever 90 when the pole is being reset by a rod 96 pivoted to a crank 99 carried by the shaft 53. In the event of breakage of the parts, the crank 99 can be secured by an adjusting- bolt to a block 114 pivoted to one of the arms 40 of the socket 13 so as to maintain a constant tension in the springs 50. The socket 13 has lugs engaging a flange on the base 10, the flange being cut away at points on a line at right-angles to the normal line of the pole, so that the socket can be readily removed and replaced on another car.
