VENDING Macnnm Application September 27, 1930 Serial No. 484,835

2 Claims. (Cl. 194-63) This invention relates to vending machines and more particularly to machines for vending bottled beverages. This applicationis a continuation in part of applicants co-pending application, Serial No. 374,674, filed June 29, 1929, wherein there is disclosed in detail a machine of this type.

An object of this invention is an improved, reliable and efficient coin controlled means for preventing operation of the merchandise delivery mechanism except upon presentation to the vending machine of the proper coin or coins.

Other objects, novel features and advantages of the invention will be apparent from the following specilication and accompanying drawings, wherein:

Fig. 11 is a Afragmentary view similar to Fig. 9 with the elements in a different position, and

Fig. 12 is a section on the line 12-12 of Fig. 9.

Referring now more especially to Figs 1 to 5 inelusive, 1 designates a rotatable drum constituting means for feeding bottles into position to be taken out from the machine by a purchaser. Rotation of the drum 1 is effected by means of a pinion 2 carried by a shaft 3 which projects through the wall of the container within which the drum 1 is mounted. The shaft 3 extends into a casing 4, having a cover 4a. To the end of the shaft 3 there is fixed a collar 5, having a pair of 'segmental projections 5a and a pair of peripheral shoulders 5b. A shaft 6 is rotatably mounted in a bearing fastened to the cover 4a and is provided at its inner end with a collar 7 having projecting tongues 7e which project between the ends of the projections 5a, thereby forming a lost motion connection between the shafts 6 and 3.

A collar 8 is keyed to the shaft 6 and has formed in one face coin grooves 8a which a face plate 8b overlies to hold coins therein. A ratchet plate 10 provided with teeth 10a is carried by a hub of the collar 8 and apawl 11 is provided to engage the teeth 10a to prevent rearward rotation thereof. The ratchet plate 10 is cut away on its periphery to provide a pair ofshoulders 10c adjacent the mouths of thecoin slots and a lever 9 having a lug 92L adapted to engage said shoulders is pivoted at 9b A spring 12 having its ends 00 connected'to thelever 9 and the pawl 11 tends to maintain both of these members in the position shown in Fig. 3.

A disk 13 is mounted on the hub of the member 8` and is provided with a pair of recesses 13b hav- 65 ing sloping sides. A lever 14 is pivoted at 14a and is provided with a pin 14b which is adapted to be received in either of the'recesses 13b. A spring 15 pulls the lever 14 in a direction to seat the pin in the recess.

The lever 9 is provided with a projection 9 which is engageable by a coin in a coin slot to lift the lever, thereby moving the lug 92L out of the path of the shoulders. A pawl 17 is provided to engage the shoulders 5'D to prevent forward rotation of the shaft 3. This pawl has an arm 17H which is engaged by an extension 9d from the projection 9c. This pawl is liftedv by the lever 9 to free the shaft 3.

In the upper part of the casing 4 there is provided coin chute 18 and selector for delivering coins to the coin slot 8a. This selector is provided with coin testing means to prevent use of slugs to operate the machine. In the bottom of the casing there is provided a chute 19 to receive coins which have been used to effect operation of the device.

The coin slots 83L are shown here as being deep enough to receive two coins, such, for exexample, as two nickels with the upper coin projecting slightly beyond the periphery of the collar 8. When the machine is at rest the collar 8 is arranged with one coin slot directly below the end of the coin chute and is maintained in this position by means of the lever 14 which tends 95 to oppose rotation of the disk. The projection 9a lies in; the path of the shoulders 1()b and will permit only limited forward rotation. The pawl 11 engages a tooth 10a to prevent rearward rotation. Should the knob 6a be turned without in- 100 serting a nickel or after the insertion of only one nickel, the extent of rotation -would Ibe limited by the engagement of the lug 9a with the shoulder.

As soonV as the knob was released it would be returned to normal position by the lever 14. After two coins have been inserted in the coin slot, rotation of the shaft 6 will bring the upper nickel into engagement with the projection 9c of the lever 9 to lift the same, thereby moving the lug 9 out of the path of the shoulder 10b. The 110 tation of the shaft 3. After the nickel has passed out of engagement with the projection 9, the

pawl 9 will be returned to operative position and the lug 9 Will be engaged by the next shoulder,

shaft 3 and prevents backlash on the shaft 6. The

arrangement of the projections 5'il and tongues 7a is such that they do not come into engagement until both the levers 9 and 17 have been lifted and the lost motion thereby provided is suflicient to permit the above described operation of the shaft 6 when insufficient coins have been presented to the machine without affecting the position of the drum 1.

Referring now to the modification disclosed in Figs. 9.to 12, a shaft 23 is journalled in the cover 25 of the housing 24, and its inner end is provided with a key to extend into a keyway provided in the end of the shaft 3 for connecting said shafts together. A handle 26 is connected to the outer end of the shaft 23 and a collar 27 is connected to the inner end thereof. Integral with this collar is a disk 28 provided with a plurality of peripheral slots 29 and a like number of spaced groups of ratchet teeth. A bell crank lever 30 is pivoted to the housing 24 and the arm 30a is adapted to engage the ratchet teeth to prevent rotation of the disk 28 in one direction. A lever 31 is pivoted to one wall of the housing 4 and is arranged to engage lugs 32 on the disk 28 to prevent rotation of the disk in the other direction. The lever 31 is provided with an arm 33 which is adapted to be engaged by a coin located in a slot 29 to lift the lever 31 against the action of its spring 34 to a sufficient extent to move it out of the path of the lugs 32. A blank space is left between the groups of ratchet teeth and the lugs 32 are so arranged that sufficient movement of the disk is permitted to engage a coin in slot 29 with the arm 33 before locking the disk against reverse movement.

A coin chute 35 is provided for directing the coin into a slot 29 and guides 36 are provided for receiving coins dropped from the disk 28 and directing the same in back of a magnifying glass 37. A pivoted detent 38 has a horizontal fiange which projects under the ends of the guide members 36 to holda coin in position in back of the magnifying glass 37. A spring 39 tends to hold the detent 38 in operative position and pivoted arms 40 are provided on the collar 27 to engage the upper end of the detent to trip the same, thereby allowing the coin to drop into the coin box 41. The arms'40 have projecting portions which engage the collar 27 to prevent rotation thereof in one direction and are provided with light springs 40a to resist yielding in the other direction.

, In the operation of the above-described mechanism, a coin, preferably a dime, is dropped into the coin chute 35 which directs it into a slot 29..

1,947,899 pawl 17 will also be raised, thereby allowing ro' The customer now turns the handle 26, thereby bringing the coin into engagement with the arm 33 to lift the lever 31 out of the path of the lug 32 corresponding to the slot containing the coin. The coin holds up the lever 31 until the lug 32 underlies the lever 31. When the lugs 32 underlie the lever 31, the pawl 30a engages the ratchet teeth yof a group to prevent rearward rotation of the shaft 23. This shaft may now be rotated forwardly until the next lug 32 engages the lever 31 which will have been released by the first lug and returned to engaging position by its spring 34. Rotation of the shaft 3 is effective to move the drum lto effect delivery of one article'of merchandise. The coin is dropped to the guides 36 and caught by the detent 38 which holds it suspended in front of the magnifying glass. On

is likewise connectedto the link 42. Thus when the lock is operated by a key, the pawl arm 30a is disengaged from the ratchet teeth and the lever 31 is lifted out of the path of the lug, thereby permitting free rotation of the shaft 23 in either direction. This mechanism is provided to permit rearward rotation of the drum, if desired.

It is of course understood that various modifications may be made in the' device above described, without in any way departing from the spirit of the invention as defined in the appended claims.

We claim:

1. In a vending machine, a rotatableshaft, a collar carried by said shaft and having coin slots,
