It is afurther object to provide a-convenient -device'in which a slug or other article inserted inthe-device-and which does not permit the operationthereof may be easily removed without injury" to the machine and'without disassembling any of the parts.

Referring to: the. drawings in detail, the embodiment illustrated-comprises a base orbracketlike support :I which .is provided with-an outwardlyx-extendingl disk-supportingshelf. 2 and an inwardly extending shelf '3, the latter being arranged. to operatively. support :a suitable mechanism:for:engagement with, and operation of, a vending control member within the vendingmachine case.

The outwardly extending shelf or disk-supportanditheficoverzk The- 2 cover: is secured. .to the-. 5-

member I and the unit may be secured to the vending machine case by means of suitable bolts 6 extending through the oppositely disposed flanges of the base and cover. The cover 4 and the outwardly extending shelf portion 2 are arranged to provide a suitable space or pocket therebetween to snugly enclose an oscillatable coin-receiving disk 1 therebetween, this disk being pivoted forv which the device is designed has been inserted,

the handle 9 may be moved to the position shown in Fig.5 and the mechanism of theivending machine will beoperated during the latter part of this movement by the consequent inward movement of a plunger I2. This plunger I2 is slidably mounted on the inwardly extending shelf portion 3 by means of a slot IS in which a suitable shouldered screw 14 is engaged. i The plunger may be provided'with a head l5 of any suitable shape for engaging with an operation controlling memberwithinthe'vending machine such as a member l6 which is diagrammatically illustratedin Fig. 3. The opposite end of the plunger I 2 is connected to a crank pin I! on a pinion IS, the

latter being rotatably mounted on the. inwardly extending shelf 3 by means of a downwardly extending bearing stud is which extends through the shoulder and is provided with a disk 20 rigidly secured thereto. A coil spring 2| is mounted between the. disk 20 and the shelf and .one end of the spring is engaged in a suitablehole in the disk and the opposite endis engaged with the shelf as illustrated in Fig. 6. Thepinion I8 is in mesh with suitable gear teeth 22 on the coin disk I and the spring 2| therefore normally tends to hold all of the parts in the position illustrated in Fig. 3 and to return them to this position after they have been moved by the operator.v

A pawl 23 is pivoted on the shelf 3 adjacent the pinion l8 and is normally retained'in the position shown in Fig. 3 by means of a spring 24.. A.

plurality of ratchet'teeth 25 are provided on the pinion I8 and these teeth are 'arranged'to cooperate with the pawl 23 a'fter the coin disk 1 has been moved a certain predetermined distance from normal. This cooperation of the pawl 23 and ratchet teeth 25 prevents the return of the coin disk and mechanism associated therewith after the coin disk has been moved a predetermined distance.

As previously stated, the cover 4 completely covers the coin disk I and is provided with a coin receiving opening 26. may be inserted by laying it fiat upon the cover as illustrated by dotted'lines at 21 (Fig. 6) and then pushing the coin forwardly until it drops into a coin-receiving opening 28 in the coin disk I. The .coin disk 1 is substantially the same thickness as the coins intended to be used therein and the opening 28 is of such a sizethat thev coin'fits snugly therein but may easily drop therefrom.

Inthe embodiment illustrated, ,a rectangular. opening .29 is provided under the coin-receiving aperture 28 in the disk 21 when. the disk is in the normal position. This is to permit :theeasy. rew A suitable coin or token.

moval of slugs as will be described later. It will also be noted, by referring particularly to Figs. 1 and 5, that the support I is provided with a slug chute or discharge passage 30 on one side of the normal position of the coin aperture, and a coin discharge chute 3| is positioned on the opposite side. The slug discharge chute 30 is so arranged as to receive certain types of slugs or coins which are smaller than the coins normally intended to be used in the machine. These small coins or slugs of small diameter will be discharged through this slug passage 30 during a limited movement of the disk I and before the pawl 23 can cooperate with the ratchet teeth 25 to prevent the return of the disk. If a coin or token of proper diameter is used, it will pass over the slug discharge chute as the opening in the chute is somewhat smaller than the diameter of a proper coin.

If an attempt is made to operate the coin disk without inserting a coin, or with certain types of slugs not filling the coin' aperture, a spring pressed pawl 32 (Figs. v3 and 4) which is pivoted in the cover 4 will drop into the coin aperture 28 as the disk is moved and thereby prevent a complete movement of the disk, and. when the handle 9 is released'the disk will be returned to its no mal position by the spring 2|.

The upper end of the small coin and slug discharge chute 30 is shown by dotted lines in Fig. 5 and by full lines in Fig. '7. This opening is elongated but somewhat narrower than the diameter of a proper coin intended to be used in the machine and therefore when a proper coin is used it will ride over this opening during the movement of the disk, and as the pawl 32 cannot drop into the coin filled aperture 28, the disk will complete its movement to the position'shown in T Fig. 3 in which position the coin will drop into an arcuate depression or visible coin slot 33 which is formed in the outwardly extendingshelf 2 and beneath the coin disk I. This depression'normally retains three coins'therein as illustrated in Fig. 7, and during the movement of the disk} with a good coin in the pocket 28, the coin slides over the top of the passage 30 and under the" pawl 32 and the downwardly extending end 34.

spring 36 and drops into the coin discharge passage 3!, which discharges the coin within the machine. the depression 33, the coin which has been de- During this movement of the coins in 7 posited in the disk aperture 28 will move to a position such as illustrated in Fig. 8 and will drop into the depression behind the preceding coins.

The disk when released will 'then return to its normal position and another coinmay be inserted. The pawl 32 (Fig. 4) is particularly 'intended to prevent the use of certain types of slugs having holes therethrough and also to prevent 3 the operation of the device when no coin has been inserted,

It will be apparent that if. a slug is inserted,-

which has a central opening therein, the pawl 32.

will drop into this opening and prevent more than a very limited movement of the disk and the disk will return to its normal position with'the tangular opening 29 below the coin aperture is 70... slug remaining in the coin aperture.

The coin disk- 1: is p-rovided'with an arcuate opening 31' which normally-registers with thecoin receivingdepression orvisible coin slot 33;

and a corresponding arcuate window 38 is provided'in the cover so that the coins may be observed therethrough. The opening 31 in thedisk is slightly narrower than the coins in the depression 33; therefore they are retainedin the slot-and cannot be misplaced by tilting the machine or by other means.

Those'skilled in the art may vary the details H of--' construction as well as the arrangement of: parts without departing from the spirit of the invention. It is desired, thereforethatthe invention belimited only by the prior art and the scope of the appended claims.
