The container is provided with an outlet pipe 8 for melted ice and this pipe is connected to a tank 9 arranged beneath the partition. The general construction of the vending mechanism herein shown forms the subject matter of a separate application Serial No. 697 ,636, filed March 1 1924, and is for the purpose of vending bottles containing beverages, The bottles are adapted to be arranged in tiers formed of side walls 10 and front and rear walls 11. These tiers are provided with downwardly inclined baflle plates 12 which are alternately secured. to the opposite side walls and are adapted to receive the bottles in a horizontal position. As shown, the tiers are divided into a plurality of sections, by means of transverse walls 13. A roller 14 is arranged beneath each tier and this roller is adapted to be rotated to deliver a single bottle from the tier at a time. As shown, the roller consists of end disks 15, which are rotatably mounted in the walls of the casing and intermediate disks 16 arranged beneath the partitions 13. Between the disks, there are provided curved plates or surfaces 17 substantially semi-circular in cross section, forming sections for the re ception of a bottle. As shown in Figure 6 of the drawings, the wall or plate of each section is arranged staggered with respect to the wall or plate of the other sections, whereby one section of the casing will receive a bottle from the corresponding com partment of the tier and deliver it. A grav ity closed gate 19 is arranged at the front of the casing and the gate is adapted to be opened by the weight of the bottle. In front of the gate, there is provided a curved plate 20 adapted to deliver the bottle in a vertical position, through an opening 21 in the front of the casing. A semicircular container or receptacle 22 is arranged in front of this opening. The bottom of the casing is providedwith a receptacle 23 for empty bottles and chutes 24 extend from the front of the casing to the receptacle. The front of the casing is provided with an opening 25, whereby empty bottles may be placed 011 the chutes 24.

The rollers 1d are adapt-ed to be controlled by suitable coin controlled mechanism. As

shown, a plate 26 is arranged on the front disk 15 of each roller and this plate is provided with suitable ratchet teeth 27, adapted to be engaged by a pawl to prevent rearward movement of the roller. The plate is further provided with a squared opening 29, adapted to receive the squared end 30 of a shaft 31. The other end of this shaft is provided with a plate or disk 32, and is further provided with a central bore 33. An operating shaft 34 is arranged in alinement with the shaft 31 and the operating shaft projects from the front of the casing. The projecting portion of the operating shaft is provided with a suitable handle 35. The inner end of the operating shaft is provided with a reduced portion 36, adap ed to be received in the bore 33. A plate 37is secured to the inner end of the operating shaft and one end of this plate is provided with a boss or enlargement 38. A slot 39, extend ing longitudinally of the shaft, is arranged in the boss 38. This slot is adapted to receive a coin passing through a slot or opening 40 in the casing. When the coin is received in the slot 39, a portion of it projects therefrom. The disk 32 is provided with radial ribs 41 adapted to be engaged by the projecting portion of the coin to couple the shafts to each other. Adjacent each rib, the disk is provided with a slot 42 and a magnet 43 is arranged in the casing in the rear of the disk. The plate 37 is provided with a lug 44 at the bottom, and the enlargement 38 is provided with a lug or projection 45. A guide is arrangedaround the disk 32 and the late 37. As shown, the guide consists of a flat plate 46, adapted to be secured within the casing and a substantially semi-circular plate 47 depending therefrom and extending around the disks. The plate 46 carries a stop 48, adapted to be engaged by the projections or lugs 44 and 45.

The indicating means forming the subject matter of the present invention are adapted to show when one of the tiers is empty and close the corresponding coin slot 40 to prevent the introduction of a coin. As shown, the front of the casing is provided with a plurality of slots or openings 49, arranged in front of and corresponding to the tiers. A card 50 is arranged behind each slot. The upper portion of the card is provided with suitable written matter 51, adapted to indicate the beverage contained in the corresponding tier, and the lower portion of the card is provided with suitable written matter 52 to indicate the fact that the tier is empty. Normally, card is behind the slot.

Figure 7 A spring 54 is arranged beneath the baflie plate. The shaft 53 is provided with a squared end 55, adapted to be received in a squared opening 56 of a link 57.

'58, it also moves the upper portion of the a The lower-baffle plate of each tier is mounted on a shaft 53 (see This link is connected to an arm 58 which carries the card 50. A lever 59 is pivoted in the casing adjacent each of the coin slots, the lever being mounted on a suitable pivot pin 60 and one end of this lever is provided with an opening adapted to receive the arm 52, as shown in Figure 4 of the drawings.

The operation of the device is as follows:

The coin controlled mechanism is adapted to couple the shaft 31 to the manually operated shaft 34, whereby the roller 14 will be turned a fraction of a revolution upon each operation of the shaft. The purchaser deposits a coin in the slot 40 corresponding to the tier containing the desired beverage, as shown by the cards 50 and the coin passes into the slot 39. The handle 35 is then turned a half revolution from its normal lowered position shown in Figure 9 of the drawings, until the lug 44 engages the stop 48. During the first part of this movement, the shaft 31 is not actuated, but when the projecting rib 41, the shaft is turned a third revolution to deliver a bottle from one of the compartments of the tier. As the tier is divided into three compartments, the parts are arranged to deliver a bottle upon each third revolution of the shaft 31. If a slug is deposited in the coin slot, the magnet 43 is adapted to withdraw it through one of the slots 42 and prevent operation of the machine. As soon as the handle 35 is released, it returns by gravity, to its initial position and the lug 45 engaging the stop 48, limits this return movement.

The lower bafile plate 12 of the front compartment of each tier is arranged on the shaft 53, as shown in ings. Normally, the weight of the bottles retains the baffie plate in lowered position against the tension of spring 54. The spring is of suflicient strength to raise the plate when the weight of the bottles is removed and as soon as this tier is emptied, the baflie plate moves upwardly, revolving the shaft 53 in a clockwise direction and causing the link 57 and arm 58 to assume the dotted line position shown in Figure 4 of the drawings, lacing the printed matter 52 behind the opening 49 to indicate the fact that the tier is empty.

During the upward movement of the arm transversely, as shown in vdotted lines, swinging the lever 59 on its pivot to place the free end of the lever beneath the coin slot 40. This prevents the introduction of a coin into the slot if the purchaser should fail to notice the fact that the tier is empty.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that variouschanges in the shape, size, and arrangement of parts maybe re- Figure 7 of the draw- I portion of the coin engages the sorted to Without departing from the spirit of my invention or the scope of the subjoined claims.
