The invention has reference to check-control devices and more particularly checkcontrol devices especially designed for use in connection with vending machines for vending articles such as matches, candies, pencils, or the like the primary object of the invention being to provide means for preventing the operation of the device b a coin or slug other than the coin or slug esigned to operate the device.

v An important object of the invention is to provide means for temporarily locking the ejector plate againstreturn movement after it has been partially moved forwardly 5 in the act of ejecting an article, thereby insuring against a person obtai'ning more than a single article, upon depositing, a coin in the coin slot.

A further important object of the invention is the provision of a sliding closure automatically operated to *close the discharge opening of the machine when the ejector plate is in its normal or inactive position,

thereby eliminating any possibility of persons obtaining articles by inserting an instrument into the article containing channels of,

the machine with which the device is used. With the foregoing and other objects in view which will appear as the description so proceeds, the invention resides in the com bination and'arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing in detail, the reference character 5 designates, the body portion of the vending machine with which the check-control device forming the essence of this invention, is used. The body portion is formed with the usual article containing compartments 6 in which articles are positioned, the articles being shown in dotted lines in Figure 5 and indicated by the reference character A. While in this invention the article .is shown in the form of a' box, it

is to be understood that various types of 1 articles such as candy, pencils or the like may be sold by this machine. a

Therefer'ence character 7 designates a supporting. plate'for supporting an ejector plate used in connection'with one of the article containing compartments, and as shown is supported directly thereunder. Guide late;

an uide the ejector plate 9 which operates thereetween. I Formed in the supporting plate 7 are slots -10 and 11 respectively, for purposes to be hereinafter more'fully described. .A cutout portion indicated at 12, which is also stantially wideisformed in the supporting plate 7 and as shown has a narrow portion 13 at one end.

Secured to the under surface of the supporting plate 7 at a point adjacent to the cut out portion 12 is a supporting bar 14 that has an offset central portion 15 formed with openings to receive the ivot pin 16, that provides a support for the li nger 17 'to which the arm 18 is pivotally connected. Formed at one end of the finger 17 is a head 19 formed with a shoulder 20 adapted to engage the bar 21 of the ejector plate 9 to prevent the ejector plate from being moved forwardly should a person attempt to operate the device prior to the po sitioning of the proper coin in the coin opening of the ejector plate.

The forward end of the finger 17 normally extends through the cut out portion 12 and is disposed in a position to be engaged by a coin resting in the coin opening 22 of the ejector plate, and if the coin is of the proper diameter, it will be seen that the finger 17 will be raised to move the head 19 downwardly, shoulder 20 being moved to disengage bar 21 allowing thev ejector plate to be moved rearwardly to a position where it may be drawn forwardly to eject an article.

Formed at one end of the arm 18 is a cut away portion defining a shoulder 25 to engage within the opening of a washer, should a washer of a size equal to the size of a coin used inoperating the machine, be positioned in the COlIl opening 22, to the end that the washer will be thrown into the money receptacle of the machine, not shown, thereby preventing the operation of the machine to eject an article therefrom.

A spring indicated by the reference character 26 is secured to the pivot pin 16 and contacts with the arm 18 which is pivotally connected with the finger 17, to normally. urge the inner ends of the finger and arm upwardly.

Secured to the supporting plate and disposed in spaced relation therewith is a stationary receiving table 27 provided with an upstanding forward portion 28 formed with a discharge openimg to permit articles vended by the machine to be forced from the machine.

This upstanding forward portion embodies side members 28 between which an adjustable block 29 is secured, so that the size of the opening through which the articles are forced, may

-' be varied to the end that the device may be employed as a machine for vending various sized artlcles.

A finishing plate 30 is secured to the side members 28 and is arranged in spaced relation therewith providing a space to accommodate the vertically sliding closure 31 which as shown is formed with rearwardly extended flanges 32 terminating in outwardly extended flanges 33, the flanges 32 operating against the side members to insure a true vertical movement of the closure 31. I

Slots 34 are provided in the flanges 33, the

slots being substantially long and accommodate the forward ends of the arms 35 that move upwardly carrying the closure 31 to its open position. Pivotally connected with one of the flanges 33 is a latch member 36 formed with a notch at its upper end designed to engage under the table 27 at the forward end thereof to normally hold the closure in its closed position to prevent persons from removing articles from the machine by inserting an instrument at the discharge opening of the machine.

This latch member is normally held in its locked position by means of the spring 37, but is moved to its inactive position by the upward movement ofthe arm 35, associated therewith. I

These arms 35 are connected at their rear ends by the plate 38 which is provided with ears to accommodate the shaft 39 that also extends through the cars 40, thereby to pivotally connect the arms to the receiving table 27. Extending rearwardly from the plate is a downwardly extended portion 41 formed with an opening to accommodate one extremity of the swinging dog 42 which is pivotally mounted on the shaft 39.

Pivotally supported in advance of the dog 42 is an elevating member 43 having an extension 44 adapted to engage in an opening 43 of the ejector plate so that further movement of the ejector plate will cause the elevating member 43 to rock to a position as shown by Figure 3where it engages the upper surface of the ejector plate forcing the arms upwardly and consequently elevating the closure to its open position.

Upon further movement of the ejector plate to eject an article therefrom, the elevating member drops into a slot of the ejector plate, allowing the arms 35 to swing downwardly closing the discharge opening of the machine.

Dog 42 operates directly over the openings 45 that are arranged in spaced relation with each other along the ejector plate, to the end that as the openings fall under the dog 42 the dog 42 will drop into these openings 'to prevent the ejector plate from being moved inwardly a short distance and then drawn outwardly to eject an article, until the ejector plate has been moved to the limit of its inward position, whereupon the dog 42 drops into the slot 46 of the ejector plate to permit the ejector plate to be returned or pulled out wardly to eject an article.

The rear end of the ejector plate extends upwardly and forwardly as at 47, the forward end thereof being extended downwardly as at 48 defining a pusher to engage the article in the machine to force it from the machine.

A finger piece 49 is secured to the forward end of the ejector plate and affords means whereby a person may move the ejector plate adjacent to the elongated opening. w

to accomplish the purpose of the invention.

ceiving table 27 which is formed with an elongated opening through which the pencils are discharged from the pencil rack, which-vembodie's inclined rods 36 disposed The stationary table also includes upstanding members 28 and a vertically sliding closure 31, there being provided a finishing plate 30' directly in front of the. closure 31. Arms 35' are connected with the sliding closure and operate in a manner as previously described. The number of'these plates 27 is controlled by the size of the machine, and on each of these plates is supported a pivoted arm indicated by the reference character 32 which arm is formed with an inclined edge 33' to be engaged by the member 47' of the ejecting mechanism, o that movement of the member 47 will cause a rocking movement of the pivoted arm 32.

'At the rear end of the arm 32- is an upstanding inwardly curved finger 34:- which moves between the lowermost pencil held in the pencil rack, and the pencils supported thereabove, to separate the lowermost pencil from the remaining pencils to prevent more than one pencil leaving the rack at as ingle operation.

The operation of the device is as follows:

A coin of the proper size is positioned in the coin opening of the ejector plate 9 and the ejector plate is forced inwardly. As the coin moves opposite to the finger 17, the finger 17 isswung upwardly causing the shoulder 20 to disengage bar 21 allowing the ejector plate to be slid to the limit of its inward movement. This pivotal movement of the finger 17 places the spring 26 under tension which throws the coin downwardly and into a coin receptacle not shown.

It will be seen that the ejector plate is held against return movement until it has reached the limit of its inward movement by reason of the dog 42 dropping into one of the openings 45 After the ejector plate has been moved to the limit of its inward movement receiving table from the compartment directly thereabove.

As soon as the article has been forced from the machine, the elevating member 43 drops into a slot formed in the ejector plate, whereupon the arms fall downwardly carrying with them the closure 31.

Should a person endeavor to operate the device by placing awasher therein, the shoulder defined by the notch will engage the washer throwing it inwardly. The shoulder 20 will now contact with the bar 21 and prevent further movement of the ejector plate.

I claim:

1. A coin controlled mechanism for a vend; ing machine including a supporting plate, an ejector plate slidably mounted on the supporting plate, said supporting plate and ejector plate having aligning openings, a finger pivotally mounted under the plates and having one end thereof normally lying within the openings, means at the opposite end of the finger for locking the ejector plate against movement, said finger adapted to be engaged by a coin positioned in the ejector plate to release the locking means to allow the ejector plate to move over the supporting plate, and means disposed adjacent to the finger for engaging a check other than a coin, for remov- 1 ing the check.

2. A COlIl controlled mechanism for a vending machine,including a supporting plate, an

ejector plate movable over the supporting plate, said supporting plate and ejector plate having elongated openings, a pivoted finger mounted under the plates, means at one end of the finger for engaging the ejector plate to restrict movement of the ejector plate, said. finger adapted to extend through the openings of the supporting plate and ejector plate to normally restrict movement of the ejector plate, said finger adapted to be moved by contact with a coin positioned on theejector plate, to release the ejector plate, and means operated adjacent to the finger for engaging a check other than a coin, for throwing the check from the ejector plate. I

In--testiniony that I claim the foregoing as my, own, I have hereto'afiixed my signature.
