    I claim:1. A vending machine comprising in combination a receptacle including a rear wall with an opening therein, sprockets secured to the ends of the shafts at the sides of the receptacle, endless chains trained around the sprockets on the upper shafts, endless chains trained around the shafts on the lower shafts, means of connec55 tion between the upper and lower shafts, the links of the lower chains having closely spaced upright lugs, the links of the upper chains having transverse rods, cards mounting articles of merchandise supported in upright position between said chains with the bottom ends there60 of in the space between said lugs and the upper ends thereof resting against said rods, means for turning one of said shafts including a toothed disc on said one shaft, a manually operated plunger, means of connection between the plunger and said disc including a lever arm 65 connected at one end to said one shaft, linkage between the other end of the lever arm and plunger, a pawl pivotally mounted on the lever arm and yieldingly pressing against the teeth on said disc.

    A vending machine comprising in combination a 70 receptacle including a rear wall with an opening therein, upper and lower shafts journalled in the receptacle, sprockets secured to the ends of the shafts at the sides of the receptacle, endless chains trained around the sprockets on the upper shafts, endless chains trained around the sprockets on the lower shafts, means of connec3 When the plunger 58 is manually pushed in, the lever arm 48 swings inwardly around the shaft 33 and forces the pawl 53 against the teeth of the disc 56 thereby moving said disc and shaft 33 a predetermined distance. The distance the disc moves may be manually adjusted by means of a lever 60 carrying at one end an arcuateshaped plate 61 disposed below the periphery of the disc 56. The position of the front edge of the plate 61 relative to the lever arm 48 determines the length of the stroke of the disc and shaft 33. The lever 60 is manually swung to the desired position, and a pin 62 extending laterally from the front end of the lever is adapted to engage selectively in one opening 63 or another of a series of openings 63 in a fixed plate 64 secured to the adjacent wall 23 of the receptacle. The plunger 50 is normally held against movement by a latching bar 65 which extends across the top of the plunger adjacent the wall 21 of the receptacle and is provided with a knife edge 66 normally extending into a notch 67 formed in the upper periphery of the plunger. The latching bar is held in the notch by means of a compression spring 68 interposed between a lug 69 on the wall 21 of the receptacle and impinging against the top of the latching bar. Mechanism is provided for releasing the latching bar 65 and this mechanism is electrically actuated upon inserting a proper coin in a slot 70 formed in the front wall 21 of the receptacle. The weight of the coin moves a movable contact against a stationary contact in the ordinary manner (not shown) of an electrical circuit powered by electricity obtained through conductors and a plug 71 adapted to be plugged into a house supply or other source of electricity. A solenoid 72 is interposed in the circuit and when the circuit is closed by the coin — —. . . the solenoid becomes energized and pulls down its arma- 35 differs from the form of invention shown in Figs. 1 12 ture 73 which in turn rocks a link 74, which pivots around pivot pin 74' thereby swinging the latching bar 65.out of the notch 67 of the plunger 50. The plunger is thus unlocked and inward manual pressure on the plunger will move the lever arm 48 as i---------- — the lever arm 48 will move the disc 56 around one step.

The drive is brought from the upper shaft 34 to. the lower shafts 38 and 39 by means of a chain 80 trained over a sprocket wheel 81 fixed on the upper shaft 34 and over a ----- — · . « , shaft 83 journalled in a bearing 84 on the adjacent side wall 23 of the receptacle. A spur gear 85 is fastened to the outer end of the stub shaft 83 and rotates therewith. The gear 85 is in continuous mesh with a spur gear 86 on the lower shaft 39 whereby said lower shaft is rotated in the same direction as the upper shaft 34, so that the upper and lower chains move in the same direction simultaneously. . .., In carrying out the invention, a site is selected ior selling the merchandise indoors, such as a store, or other structure, or for selling the merchandise outdoors such as at a fairground or in a lot or the like. The tubular housing or hopper 15 is mounted at a:convenient place at such site in an upright position. Stacks of receptacles constituting vending machines 20 are stacked around the hopper preferably to the height of the hopper or receptacle. The receptacles are secured in stacked relation by means of elongated headed bolts 90 passing through elongated tubular bearing members 91 extending along the inner surface of the sice walls 23 of ilie receptacle from front to rear thereof. The bolts pass through holes in the rear walls 22 of the receptacles and are threaded into threaded holes 92 formed in the central hopper or housing 15. The hopper has a number of such holes jCKcL WllCCl OX llACU vii tiiv u*—.· -- ----r------ - snrocket wheel 82 fixedly mounted on a stub 50 upper and lower shafts journalled in the receptacle, spiuCKCi wncvi v .
