Title: Improvements in coin freed vending machines
IPC: G07F11/28
Filed: 1955-07-08
Abstract: 789,184. Coin-freed vending apparatus. WILLIAMS, F. L., and HUBBARD, G. H. July 9, 1956 [July 8, 1955], No. 19754/55. Class 27 A coin-freed machine for vending articles such as newspapers has an inclined platform 2 with a slot 3 at its lower end and, on rotation of a knob 7 on a shaft 6, a spring-loaded shutter 11 is raised and moved sideways to uncover a delivery slot 5 and a blade 4 on the shaft 6 is rotated through the slot 3 to eject the newspaper at the lower end of the platform. through the delivery slot. To free the shaft 6, the inserted coin or coins 19 in a shoot 20 rest on the part 22 of a lever 25 and depress the lever to remove a stop 32 from a projection 18 on a lever 29 on the shaft. During its movement, the lever 29 engages the cranked end 33 of a spring-loaded rod 23 extending through the lever 25 and withdraws the part 22 from the shoot so that the coins fall to a collecting box. The effective width of the delivery slot 5 is variable by means of a spring-loaded plate 44 and knurled nuts 47. The shutter 11 is raised by engagement of the blade 4 with a lever 8 linked to the shutter but is normally locked in closing position by a spring-loaded catch lying in the path of lever 8 until moved aside by a cam on the shaft 6. The newspapers are fed forward by a plate 41 mounted on rollers 42 and carried by inclined rails 43; during insertion of newspapers, the plate can be held at the top of the inclined platform by clips 12. When all the newspapers have been delivered, a peg 49 on the plate engages a spring-loaded lever and releases a shutter which closes the coin slot and displaces a legend EMPTY instead of a legend giving the price of the newspaper. The Provisional Specification also describes adjustment of the plate 44 by cams adjusted by a lever moving over a graduated .scale.

In a preferred embodiment, the carrier means of one set are in the form of tubes 3, and the carrier means of the other set are in the form of rods which are received in the tubes 3. Each tube 3 has a axial slit 6 which receives an axial rib 9 on the rod 8 to guide the rod within the tube. The free ends of the tubes 3 are preferably connected by straps 5 to increase the rigidity of the structure. In the non-telescoped condition the ends of the rods 8 are received in the ends of the tubes 3 and are retained by mating grooves and ribs 11, 12; an axially applied force releases the mating condition for telescoping of the carrier means. In a further embodiment; each set comprises alternately arranged tubes and rods which are connected together at their free ends in pairs to constitute the carrier means. In a further embodiment, each carrier means comprises at one circumferential edge a dovetail shaped portion and at the other circumferential edge a portion which mates with the dovetial shaped portion. In order to reduce the resistance to bending of the carrier means at their portions adjacent the spaced rings 1, 2, it is proposed that part of the wall of the carrier means be cut away in this area whereby shrinkage of yarn during heat or dyeing treatments may be accommodated. The package carrier may be made of steel but is preferably made of plastics.

The partition 38 is movable to increase the proofing space. Each baking tin comprises two triangular halves 32a, 32b hinged together at 44 and held close together by projecting pins 50, 52 fitting into a tumbler plate 42 at each end, the plates 42 being suspended on the conveyer pivot pins 43. When the chains round a sprocket 25 one of the sprocket striking pins 55 engage a notch 56 in the sprocket plate whereby the latter is gradually turned upside down, Fig. 6, so that the pins 50 slide in the slot 53 and separate the tin halves from each other so that the loaf can drop out on to transverse conveyer 36. The opened tin halves then pass through a cooling chamber 15 and to sprocket 20 at the loading position 30 where the tin halves are filled with dough. Beyond the top of the sprockets 20 the tumbler plates come against fixed striker pins 60, 61, Fig. 5, which turn the plates 42 at right angles which operation closes the mould halves together. In another form, Fig. 7, a series of superposed tins 32 are mounted between end plates 70 forming a cage running on a mono-rail 60 and pivoted at 62. Swinging the cage in one direction for 90 degrees about 62 opens the mould to receive dough. After baking by traversing through an oven, the cage 70 is swung 90 degrees in the opposite direction whereby the slots 53 open the moulds to discharge the loaves. Such movement may be done by hand or mechanically.
