Abstract: 710,877. Coin freed machines for selling heated foodstuffs. CLAUSEN, J. A May 25, 1951, No. 12323/51. Class 27 Heating and cooling contents. Storage details. Casings. Boiled sausages are stored separately in cylinders, Fig. 4, formed with perforated walls 5 and disposed in vats 1 (see also Fig. 1), containing water heated by electric heaters 2 controlled by thermostats. When a coin is inserted in the machine the base 6 of one of the cylinders is raised to eject the sausage by means which are then shifted to the next cylinder. The ejected sausage falls into a channel 12 which ' communicates with a tube 13, Fig. 1, by which the sausage is guided to a chamber 14 in which a piece of paper has been placed to receive it and from which it may be removed by the purchaser. The tube 13 is formed near the chamber 14 with a bend 58 by which the speed of the sausage is reduced.: the bend is perforated at 59, Fig. 5, to permit water carried over with the sausage to escape to a drip tank 60, Fig. 1. The vats 1 are kept filled to a constant level by float-operated switches which control a pump and solenoid - operated valves to supply water from a tank, 55, Fig. 1. The tanks 55 and 60, and the vats 1, are mounted on rails 74 to facilitate their withdrawal and replacement when empty. The electrical connections to the heaters in the vats 1 are made by plugs on the tanks which fit into fixed sockets when the vats are pushed into position. The pipe leading from the tank 55 is raised about a flexible joint when the access door in the side of the casing is opened. A mustard dispenser 70. which may be coin freed, is provided above the chamber 14. Coin action, weight. An inserted coin momentarily closes a switch (not shown) for the driving motor, the circuit being subsequently maintained for the proper period by a switch closed by a cam (not shown) driven through gearing from the motor. Delivery of articles: sausages. A sausage is raised from its cylinder 4, Fig. 4, by raising the base 6 and is deflected on to the channel 12 by a guide 10. The base 6 is raised by a rod 8 provided with an arm 9 which is engaged by one of a pair of projections 16 on a chain 15 passing. over sprockets 17, 18 of which the former is driven at each operation of the machine through a gear 25 from a toothed sector 26 which makes a single revolution at each operation of the machine. During the second half revolution of the sector 26 it is connected by gears 31, 30, 29, 28, 27 to drive a screw 23 on which is threaded a yoke 22 by which the sprockets 17, 18, which are respectively splined to and free on their shafts 19, 21, are slid into position for engagement with the arm 9 associated with the next cylinder 4. A chain and sprocket mechanism and associated gearing as described above is provided for each of the vats 1 and each mechanism is driven in turn through gearing from a mutilated gear (not shown) driven from the driving motor and provided with teeth which engage successively with each of several pinions associated each with one of the delivery mechanisms. At the end of each traverse of a pair of sprockets 17, 18 the associated yoke 22 strikes a pin to operate a linkage by which a plate 33 carrying the gear 29 and a further gear 32 is turned about the shaft 34 to bring the gear 32 into mesh with the gear 28 so reversing the direction of traverse of the sprockets in preparation for a further cycle of operation when the machine has been replenished. Some of the sausage vats may be disposed below the delivery aperture, to which the sausages are delivered by a conveyer. The chamber 14 may normally be closed by a member which, when swung open, moves suitable closures over the apertures by which sausages and papers enter the chamber. Delivery of sheets. The sheets of paper for receiving the sausages are delivered from a magazine 61, Fig. 5, by a pusher device 65, against which the sheets are pressed by a spring biased plate 62, to a pair of driven rollers 67 which deliver the sheets to the chamber 14. The mechanism operating the pusher member 65 is not described.
