-CALIFORNIA, A GORPORATION F GALI- rnncrnvnnnine MACHINE.

Application filed September 9, 1924. stamina. 736,779.

This invention relates to coin operated vending machines in general but in particular to a machine especially equipped to vehd elongated. articles such as pencils, candy sticks, and the'like.

The objects of the invention are to provide a verysimple inexpensive mechanism which will carry out'the purpose of the invention and which will be controlled by a single rotary normally locked shaft which is released bythecoin and in t'urnejects the pencils one at a time from a bin in which they lie parallel to the shaft.

In the drawingshereto Figure 1 is a front elevation of my machine, Figure 2 is an enlarged fragmentary section of the pencil ejecting mechanism as seen from the line 22 of Figure 1, and Figure 3 is a similar fragmentary view of the coin released ejector shaft lock. Figure 4 is a detail view of the mating hook.

In further detail the drawings show at l a cabinet with a vertical partition 2 forming on the left side a pencil bin or hopper 3 and on the right side a space for the coin and coin controlling mechanism.

The front of the cabinet is closed by a door 1 preferably having a glass panel 5 in front of the pencil bin. This door is cut out along its lower edge at 6 for emergence of the de livered pencils which roll down inclined strips 7 below the bin and are stopped by lips 8 at the end of the strips.

The actual bottom of the bin consists of a slanted shelf 9 upon which the pencils 10 rest and always tend to roll toward the door of the machine; and the shelf terminates short of the door so that one pencil only can fall through.

Just below the shelf is a single rotatable shaft 11 which operates the whole device upon turning the crank 12.

This shaft is normally locked against turning, and secured to it are two circular carriers 13 positioned relative to the shelf and door as shown in Figure 2 and having each a notch 14 adapted to align with the space in front of the shelf to receive a pencil falling through as indicated.

These circular carriers are each provided with a projection 15 passing through slots 16 to the shelf to function as jarring devices to loosen up the pencils and throw one for.-

toengage a pin or stop to ward and insure its falling through the space V pencil space in front ofthe shelf as described by mejz'tns of a special cam hub 18 secured to the shaft adjacent the right hand wall of the cabinet and which hub has a 111g 19 adapted determine its return movement, while a similar pin 21 determines its forward movement.

This cam hub 18 is positioned adjacent the lower end of a coin slot 22 and on one side offset from the slot it his a hook formation- 23 adapted to hook against a mating hook 24 formed on the end of a swinging device 24 and prevent it from being turned to the right for discharge of the pencil from the carriers.

This device 241- may assume a variety of forms but is here shown pivoted at 25 to a boss on the side plate 26 of the coin chute and resiliently forced in direction of the cam hub by a flat spring 27 secured at 28 to the rear wall 29 of the cabinet all as shown in Figure 3.

The coin chute is cut away at its rear lower end to pass a laterally extending flange 30 of the locking device 24L and which flange takes a position in back of a coin falling down the slot to the point as indicated at 3'1. and the flange extends under the coin slight- 1y as shown at 32 to keep the coin from falling entirely through.

when a coin is in the slot and resting against the flange as shown it lies almost in edge contact with a cam 33 formed on the hub along side of the hook portion 23 so that when the coin is in place and the crank is turned to the right the coin is contacted by the cam and pushes the locking device toward the rear wall of the cabinet and thereby makes the hooks 23-24 inoperative.

forces the coin into the box 34 below.

W en th handle i released the shaf a once revolves to the starting point bringing the hooks 23-24 into locking engagement until another coin is deposited in the slot.

The stop 20 is so placed as to provide sufficient backlash so that the cam 33 can act on the coin before the hook 23 has moved sufiiciently to engage the stop hook 24.

In contemplating my invention it will be seen that a single revolvable shaft carries the locking device, the releasing element and the pencil ejector-s so that their cooperation cannot be destroyed through wear of the machine, and while I show and describe it as arranged for vending pencils, it is manifest that with suitable modification of the ejecting carriers, it may be adapted to dispense other articles of merchandise, and also that the notches in the carriers may be deep enough to dispense from one to any desired number of articles as may be desired.

I claim:

1. In a coin controlled mechanism for vending machines, a shaft, a hub member secured to the shaft, means for restricting the hub member and shaft to an oscillatory motion, a cam on the hub member, a shoulder on the cam, a coin chute having its discharge end adjacent the cam, and a locking device having a projection adapted to be engaged by the shoulder for locking the shaft against oscillation, and having a flange coacting with the chute to support a coin therein in a manner to retain the coin in contact with the cam, said device including means by which it is yieldahly urged to one position in which its projection is spaced from the shoulder but in the path of movement thereof and movable to another position upon partial rotation of the cam in one direction through the coaction of the latter witha coin in the device to move the projection out of the path of movement of the shoulder so that further rotation of the cam can be effected to discharge the coin from the device.

2. A coin controlled mechanism for vending machines as embodied in claim 1, wherein the first means comprises a lug on the hub, and pins in thepath of movement of the lug.
