Abstract

The coin mechanism of this invention is in reality a type of adding machine. Nickels, dimes and quarters inserted into the mechanism enter into and pass through their respective coin chutes, as the coins travel through the chutes they actuate crank plates and linkage, that in turn cause a circular spaced ratchet plate that is rotatably mounted on the coin mechanism base plate to rotate in a limited manner, each ratchet tooth of the ratchet plate represents one nickel. When a nickel is inserted into the coin mechanism, the ratchet plate is rotated a distance of one ratchet tooth. When a dime is inserted into the coin mechanism the ratchet plate is rotated two ratchet teeth. When a quarter is inserted into the coin mechanism, the ratchet plate is rotated five ratchet teeth, each time the ratchet plate is rotated, it is locked in the furthermost rotated position by a stationary ratchet pawl. Thus, if one nickel, one dime and one quarter are inserted progressively into the coin mechanism the ratchet plate will be rotated eight ratchet teeth past the normal position, representing a coin value of forty cents. A circular price setter plate is located adjacent to the ratchet plate on the opposite side of the coin mechanism base plate, the price setter plate is rotatably mounted on the ratchet plate shaft that extends through the base plate, in a manner that it can be set to accommodate any one of the coin mechanism''s selling prices. The price setter plate has holes pierced through the plate on a slightly smaller radius than that of the outside radius of the ratchet plate to correspond to the number and spacing of the ratchet teeth of the ratchet plate, these holes provide means for setting the plate to accommodate the various price requirements. An opening cut inwardly from the outside of the price setter plate provides means for releasing the door or other locking elements of a vending machine, when the proper amount of coins are inserted into the coin mechanism, the price setter plate can be preset in increments of one nickel to trigger the release of the door or other locking components of a vending machine at any figure from five cents to one dollar and fifty cents.

When a dime is inserted into the coin mechanism the ratchet plate is rotated two ratchet teeth. When a quarter is inserted into the coin mechanism, the ratchet plate is rotated five ratchet teeth, each time the ratchet plate is rotated, it is locked in the furthermost rotated position by a stationary ratchet pawl. Thus, if one nickel, one dime and one quarter are inserted progressively into the coin mechanism the ratchet plate will be rotated eight ratchet teeth past the normal position, representing a coin value of forty cents. A circular price setter plate is located adjacent to the ratchet plate on the opposite side of the coin mechanism base plate, the price setter plate is rotatably mounted on the ratchet plate shaft that extends through the base plate, in a manner that it can be set to accommodate any one of the coin mechanisms selling prices. The price setter plate has holes pierced through the plate on a slightly smaller radius than that of the outside radius of the ratchet plate to correspond to the number and spacing of the ratchet teeth of the ratchet plate, these holes provide means for setting the plate to accommodate the various price requirements. An opening cut inwardly from the outside of the price setter plate provides means for releasing the door or other locking elements of a vending machine, when the proper amount of coins are inserted into the coin mechanism, the price setter plate can be preset in increments of one nickel to trigger the release of the door or other locking components of a vending machine at any figure from five cents to one dollar and fifty cents.

INVENTOR KARL KNICKERBOCKER COIN MECHANISM FOR VENDING MACHINES The present invention relates to mechanism for controlling a latch or the like for the door or other dispensing element of a vending machine which is permitted to be opened or operated when proper coins have been deposited in the 'mechanism.

The present invention relates to a new principle in mechanical coin operated mechanism, that is a radical departure from the principle incorporated in existing and commonly used coin mechanisms such as U. S. Pat. No. 3,265,177. In that type of a coin mechanism, inserted coins are stacked edgewise in one or more vertical coin chutes. Inasmuch as the vertical length of the coin chutes are limited by necessity of allowable space, a vendor or newspaper rack equipped with this type of a coin mechanism will be limited to low selling prices, if a purchase is made from the vendor with nickels only, the selling price will be limited to 30 cents.

A very important feature of the present invention is, a vendor or newspaper rack equipped with this unit will accommodate selling prices from cents to 1 dollar and 50 cents. Prices can be varied in increments of 5 cents by turning a price setter dial, no tools or extra parts are required to attain a required price setting.

A still further object of this invention is to provide a coin operated mechanism having means for presetting the price control elements of the coin mechanism to correspond to any one of a vendors required merchandise selling price.

Another important feature of this invention is that vendor merchandise can be purchased with any combination of coins that total up to the vendors pre-set selling price.

Another important feature of this invention is, any combination of coins required to make a purchase from a vendor, can be deposited in the vendor in any rotation.

A still further object of this invention is to provide a mechanism of the type referred to that will operate in response to various coin combinations.

A very important feature of this invention is coins deposited in the vendor are temporarily held in an escrow container, a potential purchaser can return these coins to the coin return receiver by operating a coin return actuator.

Another feature of this invention is the vendors coin return actuator is locked to prevent the return of coins when a dispensing cycle of the vendor is initiated.

Another feature of this invention is that during a dispensing cycle of a vendor, coins held in the escrow container are transferred from the container to the cash box.

Another important feature of this invention is that it provides means for the quick setting of the price control components of the coin mechanism to accommo date the change from the daily setting price to the Sunday selling price of newspapers being dispensed from a newspaper rack.

In a multiple column merchandise vendor, it is common practice to sell the merchandise from one of the columns at one price and the merchandise of another column at a different price, the present invention is equipped to perform this function.

This invention provides a coin mechanism that can be quickly and easily secured to or be completely removed from a vending machine, without the use of tools.

Another important feature of this invention is the coin mechanism referred to, can be operated in con- 5 junction with or without a standard slug rejector.

When a newspaper rack is equipped with a coin mechanism of the present invention, a special coin sorter and bent coin rejector may be attached to and become a part of the coin mechanism, this unit is not a part of the present invention.

Other objects and advantages of this invention will be apparent from the following specification and drawings.

FIG. 13 is a rear elevation, exploded view of the combination ratchet and price setter mechanism having sections of the mounting housing cut away to show the shaft bearings.

FIG. 14 shows a front and side elevation of a newspaper rack demonstrator equipped with a coin mechanism of the present invention.

Referring to FIG. 1 of the drawings, the coin mechanism of this invention is shown mounted on the front inside wall 1-8 of a newspaper rack coin mechanism housing, to conserve space, the rack housing part of the drawing is a fragmentary section. The newspaper rack's door extension 2 and the coin mechanism angle plate extension 72 have been cut away in a manner that the rack door latch hook plate 35 and coin mechanisms latch plate 36, also the front portion of the coin mechanisms ratchet plate return crank plate 32 can be viewed. It will be noted that the left end of latch plate 368 has dropped over the hook section 35A of door latch hook plate 35, the rectangular slot 36A in latch plate 36 makes the latching possible. Plate 33 is rigidly secured to the inside top wall of latch plate 36 extends downward from that point on an angle and comes in contact with section 35B of the door latch hook plate 35, to rock the latch plate 36 counter-clockwise on its mounting shaft 32A. When latch plate 36 is rocked clockwise, connecting link plate 39 having its lower.

end secured to a tab 37 on the top front end of latch plate 36 by shoulder stud 38 and the top end secured to hinge plate 41 by shoulder stud 40. Hinge plate 41 is swingably mounted to channel section of plate 45 by shaft 29, 41A of plate 41 is a tab formed outward at a right angle to the plate this tab normally rests on the top outer left end of plate 45 and limits the downward travel of the left end of plate 41 that is being'biased by tortional spring 43. Tortional spring 43 is mounted around shaft 29, between the channel shaped walls of plate 45. The lower end of the tortional spring 43 is anchored to plate 45 the opposite end rests against tab 41A of plate 41. Plate 45 is'swingably mounted on shoulder stud 28 that in turn is rigidly secured to the coin mechanism base plate 1, an expansion spring 151 having the upper end anchored to plate 45 through opening 151A and the lower end secured to shoulder stud that is rigidly rivited to the coin mechanism base plate 1, biases plate 45 to rock on its pivot stud 28 clockwise. The clockwise travel of plate 45 is limited by link plate 39 being anchored to latch plate 36 that in turn has its clockwise travel limited by angle plate 33, that is a part of the latch plate 36 coming to rest against section 35B of latch hook plate 35. The extreme right end 49 of plate 45 is formed outward at a right angle to the plate and extends over the top side of the price setter plate.

When the paper removable door 2 is swung outward, the latch hook plate that is secured to the door extension moves away from latch plates 36, angle plate extension 33 and allows the latch plate 36 to rock on its mounting shaft 32A clockwise. It is obvious that the clockwise movement of the latch plate 36 will permit angle section 49 of plate 45 to come to rest on the top edge of the price setter plate 11, thus stopping the clockwise travel of the extreme left end of the latch plate 36A, therefore preventing the latch plate 36 from disengaging latch hook 35A of latch hook plate 35. It will be noted that the price setter plate 11 in this instance is set to accommodate a 35 cent sale. It will therefore be necessary to insert thirty five cents into the coin mechanism, to rotate the price setter plate 11 clockwise to position opening 118 of the price setter plate directly under angle section 49 of plate 45. With the price setter plate 11 in this position, angle section 49 of plate 45 will enter opening llB'of the price setter plate 11, therefore, when the top of the paper removal door is swung outward the added clockwise travel of plates 41-45 and linkage 39 will permit section 36A of latch plate 36 to-disengage section 35A of the door latch hook plate 35 and release the door. When the paper removal door is swung open, the price setter plate is returned to normal position as shown in FIG. 1 of the drawings in the following manner; 32 is a crank plate swingably and coaxially mounted on the coin mechanism base plate 1 by shoulder stud shaft 32A that in turn is rigidly secured to the base plate 1 section of crank plate 32 and extends outward on a horizontal plane from each side of the channel shaped mounting section, of the crank plate (not shown) shoulder stud 32B is rigidly secured to the left end of crank plate 32 and extends inward to pass over section 34 of door latch hook plate 35. Crank plate 32 is biased to swing counter-clockwise by expansion spring 152 that has the lower end anchored to crank plate 32 through opening 153, the upper end is anchored to shoulder stud 150. When the top of paper removal door is swung outward, shoulder stud shaft 32B, that is riding on section 34, of door latch hook plate 35, will follow the ramp shape section 34A of the plate and swing downward the right end of the crank plate will be swung upward. 30A is a section of crank plate 30 that is formed inward from the plate at right angles to the plate, to pass through opening 30F of the coin mechanism base plate 1 and under section D of the stationary ratchet pawl 20, that is mounted on the opposite side of the base plate. By referring to FIGS. 8 and 9, it will be obvious that the ratchet and price setter plates that are held in their rotated positions by the stationary ratchet pawl 20 will be released. However, inasmuch as angle section 49 of plate 45 has dropped into opening 118 of the price setter plate 1 1, it will prevent the return of the ratchet and price setter plate to normal position, therefore, connecting link plate 46 that has the top end connected to plate 45 by shoulder stud 47 and E washer 48 and the lower end connected to crank plate 32 by shoulder stud C will rock plate 45 counter-clockwise, angled section 49 of plate 45 will move out of opening 118 of the price setter plate 11, thus the plates 11 and 25 will return to normal position. These plates are biased by a tortional type clock spring that will be outlined in detail later on in the specification.

When the paper removal door 2 is closed, shoulder stud 32B of crank plate 32 will come in contact with the ramp 34A of door latch hook plate and force that end of crank plate, that was lowered by the opening of the door 2, upward to normal position, the opposite end of crank plate 32 will move downward and release the stationary ratchet pawl 20. Section 36A of latch plate 36 will come in contact with the ramp 35C of the door latch hook plate 36 and cam that end of the latch plate, that was lowered by the opening of door 2 upward to normal position. It will be obvious that it will be necessary for the outer left end of hinge plate 41 to swing upward on pivot shaft 29, inasmuch as angle section 49 of plate that is a part of that assembly will come to rest on top edge of price setter plate 11, as the door 2 latch hook plate moves inward it will come in contact with plate 33 of latch plate 36 and rock the latch plate counter-clockwise into latched or normal position. MOst of the coin mechanism s components shown in FIG. 1 are also shown in FIG. 2.

The functions of the coin mechanism components, identified in accordance with their part names, will be elaborated on as the specification progresses.

Referring to FIG. 5 of the drawings, the sequence of operation of the quarter crank plate and associated actuator components are outlined in detail. In FIGS. 5 and 6 all components are shown in normal position.

FIG. 6 of the drawings shows the quarter crank plate 32 rotated clockwise on mounting shaft 14, by the presence of a quarter in the coin chute, the right end of crank plate angle section 30A of plate 32 has come to rest on the lower end of the quarter coin chute face plate 68 cam slot 68A, the quarter is shown leaving the chute. The left end section 32D of crank plate 32 has been rotated upward. Ratchet actuator plate 18 is rotated counter-clockwise on its mounting shaft 92, by connecting link plate 27 that is attached to the right end of ratchet actuator plate 18A by shoulder stud 24. The lower end of link plate 27 is attached to section 32D of quarter crank plate 30 by shoulder stud 23. Angle section 26A of ratchet pawl 26 that is swingably mounted on the right end section 18D of ratchet actuator plate 18 by shaft 18A, thus rotating the ratchet plate 5 teeth. All actuator components will return to normal position when the quarter leaves the coin chute, with the exception of the ratchet plate 25 that will be held in its rotated position by stationary ratchet pawl until newspaper rack removal door 2 is opened.

Referring to FIG. 7 of the drawings, the combination dime-nickel crank wire 61 and associated components are shown in normal position.

In FIG. 8 of the drawings, the dime crank wire 61 is shown rotated clockwise on mounting shaft 14, by the presence of a dime in the coin chute, the angle section 61A of crank wire 61 has come to rest on the lower end of the chutes divider plates 70-71 cam slots 68A. The dime is shown leaving the chute. The dime crank wires associated cam plate 60 that is coaxially mounted between the quarter cranks 32 channel sections, on shaft 14, has been rotated clockwise by the presence of a dime in the chute. The upper left section 61D of the cam plate 60 contacts the lower side of the ratchet pawl 26 mounting shaft 13A that is anchored to the right end of the ratchet actuator plate 18, to rotate the components counter-clockwise on mounting stud 92, also rotate the ratchet plate counter-clockwise two teeth. Stationary ratchet plate angle section 20B of stationary ratchet pawl 20 that is mounted on stud 21, will prevent the ratchet plate from returning to normal position until paper removal door 2 is opened. All other actuating components will return to normal positions when the dime leaves the chute. 7

Referring to FIG. 9 of the drawings, showing the nickel coin chute structure, combination dime-nickel crank wire 61 and its associated components are shown in their respective normal positions.

FIG. 10 of the drawings shows the combination dimenickel crank wire rotated clockwise by the presence of a nickel in the coin chute, the bottom section of the crank stop plate 101 has been crowded to the left by the nickel to bring section 1018 of the stop plate 101 directly under extension 61B (best shown in FIG. 12 of the drawings) of crank wire 61 and stop the downward travel, thus limiting the rotation of cam plate 60, ratchet actuator plate 18 and ratchet pawl 26, in a manner that ratchet plate 25 will rotate only one tooth. When the nickel leaves the chute, as shown in phantom, crank wire 61 and associated actuator components of crank wire 61 will return to their normal positions, with this exception, ratchet plate 25 will be held in its rotated position by stationary ratchet pawl 20, until the newspaper rack removal door 2 is opened.

Summing up the operation of the present invention is as follows:

One of the distinctive features of the present invention which contributes primarily to the simplicity of construction and relative low cost of manufacture, is that in the present invention the ratchet plate 25 and the price setter plate 11 which control-the release of the newspaper dispensing door are operated through simple inexpensive structures solely by the weight of the coins deposited in the chutes without the use of escapements and other delicate complicated mechanisms.

When the vending machine is charged or filled with a supply of newspapers or other periodicals to be dispensed, the price setting plate 11, which is in the form of a semi-flexible disc is flexed to disengage it from the setter index pin 10 on the price setter plate actuator crank 9 which is rigidly attached to the ratchet and price setting plate carrying shaft 6 and rotated to bring the hole of the circularly spaced holes extending through the price setter plate 11, which corresponds to the price of the newspaper to be dispensed and the pin 10 enters through the hole in the price setter plate or disc, in effect locking the disc 11 to rotate with the shaft and ratchet.

For example, if the price of the newspaper to be dispensed is fifteen cents, the price setter plate 11 will be rotated from its normal position so that the pin 10 will extend through the third hole from normal or starting position of the price setter disc 11 and upon insertion of a nickel in the nickel chute, the weight of the nickel engaging the nickel and dime wire 61 will, by its weight, move this wire downwardly and move the ratchet rotating plate or arm 18 a distance sufficient to rotate the ratchet one tooth, then when a dime is inserted in the dime chute it will engage the nickel and dime wire 61, moving it and causing the cam on its end to move the ratchet rotating arm 18 or plate 11 a distance sufficiently to rotate the ratchet in an increment of rotation constituting two teeth, thus the price setter plate 1 1 will have been rotated through the three tooth increment corresponding to the setting of the price setter plate 11 by the insertion of the crank arm carried pin 10 through the third hole in the price setting plate. This will move the notch or opening 11B in the perimeter of the price setter plate 11 into a position where the angled end 49 of the pivoted door latch release arm 45 will drop into the notch or opening 113 releasing the door catch and allowing the dispensing door to be opened for removal of a newspaper from the machine. During this operation, ratchet pawl 26 that is mounted on the outer end of ratchet rotating plate 18 to rotate the ratchet, also the stationary ratchet pawl 20 that is mounted on base plate 1 will be rocked clockwise to remove the pawls from the ratchet teeth and the ratchet and price setter plates will be returned to their normal starting position by means of the flat wire tortional spring attached thereto. During this operation, the latch releasing arm 45 is moved so that the angled section 49 on its end moves out of the opening or notch 118 in the perimeter of the price setting plate or disc 11 and rides above the perimeter of the price setting disc or plate 11 until the mechanism is again operated by insertion of coins in the slots.

When the price of the newspaper or periodical to be dispensed is either 25 cents or a price including 25 cents, such as 35 cents or 40 cents, the price setter plate 11 will, after having been manually flexed to move the crank arm 9 carried pin 10 out of an opening therein, be rotated so that the pin will pass-through the opening corresponding to the price of the newspaper and thus the mechanism will be set so that the door latch will not be released until coins of value corresponding to the setting of the price setter plate have been inserted into and passed through the coin chutes. These coins may be inserted in any degree of sequence, say for instance, the price setter plate 11 is set at 40 cents, then the coins may be inserted in any sequence and upon the insertion of each coin, the ratchet will be rotated by the weight .of the coin passing through the chute through the'intermediate mechanisms a number of notches corresponding to the value of the coin and when a total of coins to the value of 4.0 cents have been inserted, the ratchet and price setter plate 11 will have been rotated a distance sufficiently to release the dispensing door latch 36 and allow it to be opened. That is, when a quarter, a nickel or dime have been inserted in the chutes, for dimes or eight nickels or any combination thereof amounting to 40 cents have been inserted in and passed through the coin chutes.

When a quarter is inserted in the quarter coin chute, the quarter passing through the chute will engage angle section 30A of the crank arm 30, moving this arm 30 and by the linkage 27 connection between the crank and the pawl carrying ratchet rotating arm 18 move this latter arm a sufficient distance to rotate the ratchet through an increment of rotation designated by five ratchet teeth. Due to'the fact that a quarter is relatively heavy with reference to the weight of a dime or a nickel, and due to'the fact that the spring connected to the ratchet and the ratchet operating arm or plate 13 must be so'delicately balanced as to be operated by the relatively light weight of a dime, the weight of the quarter mayexert momentum to the rotation of the ratchet as to cause it to overreach the prescribed degree of rotation causing excessive rotation of the price setter 11 and prevent unlocking the door latch. To prevent this, the stop 91 is provided, so that when the ratchet has rotated through a five tooth degree of rotation the stop plate 91 will engage the pawl 26 carried by the ratchet rotating plate or arm 18, force it into firm engagement with the fifth tooth of the degree of rotation and prevent any over-reaching movement of the ratchet and price setter plate 11.

While the price setter plate in the present application is shown provided with thirty price setting holes to permit the dispensing of periodicals or articles ranging in value from cents to 1 dollar and 50 cents, it is to be understood that the invention is not limited in this degree, but that the price setter plate may be provided 'with any desired or predetermined number of openings to increase or decrease a maximum coin amount required for operation of the mechanism and correspondingly increase or decrease the cost of the periodicals, such as one nickel to the maximum of a dollar, or one nickel minimum to a maximum of two or more dollars, or increments thereof without departing from the spirit of the present invention.

It will be apparent that only one form of the invention has been described and shown in the drawings, other forms, modifications and adaptations could be made, all falling within the scope of the following claims.
