17 Claims.

This invention relates generally to certain new pensing and sundry apparatus to which such coin devices are applied.

Another object of the invention is to provide a,

- coin slide structure whose parts are so designed 15 as to limit and obstruct the movement of the slide s'erted in the device and permit of the proper or acceptable movement of the slide when a proper coin is used, such structure embodying means 20 rendered operative or inoperative, depending on whether a coin or slug is inserted in the coin slide,

to predetermine the proper movement or obstruction of the coin slide and thence the operation or non-operation of the apparatus to which 25 the coin slide structure is applied.

A further obje'ctis the provision of a coin detector mechanism which is simple, compact and durable inconstruction, which is positive and reliable in operation, which embodies in its concept 30 the structural make-up of a minted coin as compared with that of a slug or other coin imitation to render the slide operative or inoperative, and

which reduces to a minimum the use of spurious coins and assures the owner or operator of the 35 apparatus, to which such coin devices are applied, against the great loss which operators are obliged to accept with thecoin devices now on themarket.

Other features of the invention reside in the,

construction and arrangement of parts herein- 40 after described and particularly pointed out in the appended claims.

as performed in accordance with my coin device. 15 member should a slug or coin imitation be in-- Similar characters of reference indicatecorresponding parts throughout the several views.

In its general organization, my improved coin slide mechanism comprises a body or guide member in which a coin-receiving slide is mounted for properly delivering the coin upon pushing the slide to a position where it will be discharged to a suitable coin magazine and thereupon initiate the action of the vending machine, phonograph, or like apparatus to which the coin slide mechanism is connected; means operatively. associated with the coin-receiving slide to normally latchthe slide against movements beyond predeterminedpoints or stages in the slide-stroke, such means being disposed for actuation by a proper and genuine coin to release the slide at the respective stages of its movement and permit the full stroke .to be imparted to the slide to enable the coin to be discharged from the slide and render operative the apparatus to which the coin mechanism is applied; and means disposed in the operating path of the coin slide and designed to effect .1. tilting or displacement of spurious coins and slugs in such a manner as to displace them out of the plane of operation of the coin-slide latching 40 means with the result that "such means are not actuated to a released position, but remain latched to prevent forward advancement of the slide'as well as to likewise prevent-operation of the apparatus to which the coin device is attached. Thus, when a slug or imitation coin is inserted in the coin slide, the latter is advanced a predetermined distance to the first coin-detecting zone or stage when its further movement is arrested by the inability of such slug or imitation coin to release the latching means from the slide, after which it is necessary to retract the slide to its initial position, remove the slug or spurious coin, and place a proper minted or acceptablecoin ll the slide'to insure operation of the apparatus i bearing the coin device. The means which cause a tilting displacement of slugs and spurious coins out of a normal level position in the slide have no effect whatever on genuine or minted coins, dueto the edge contour or characteristics thereof as compared with those of spurious coins, so that such genuine or acceptable coins remain in their normal level position and in a plane where they will engage the latching means and release such means from the slide so that the coin will be properly advanced through the slide mechanism.

i Referring now to the drawings, wherein I have shown a preferred embodiment of my invention,

l 5 indicates a channeled body or guide member of 1 the apparatus which is usually disposed in a substantially horizontal position and has an attaching plate l5 for securing it to the coin-controlled apparatus. Slidably mounted on this guide member is the coin slide I 1 having an aperture I8 for the reception of a proper coin,'the coin being supported on the floor or bottom of the guide member during the movement of the slide. Forwardly of the attaching plate I6, a guide member is preferably horizontally divided to provide a lower section l9 and an upper section 20, the sections being joined by screws 2| or the like. As seen in. Figure 5, the coin-receiving aperture i's-open at one side to expose the adjoining portion of the coin to those stages in the movement of the coin-slide to the means which act to deflect a spurious coin to a position where it is inoperative to release the latch means of the coin-slide, and by preference those side edges of the slide adjoining the open side of the aperture converge gradually toward the aperture. usual operating handle 22 while its opposite or rear end has a stop lug or abutment 23 arranged to engage the adjoining portion or the guide member section H to limit the retraction of the coin slide. The lower section IQ of the guide member I5 is provided in the bottom of its rear end with a discharge opening 24 with which the slide-aperture I8 is adapted to register, when a proper coin has been advanced a predetermined distance, to effect the discharge of the coin by gravity through such opening and thence to the coin magazine mechanism of the phonograph or other. coin-controlled apparatus' If desired, a chute member or deflector 25 may be disposed immediately below the discharge opening 24 and an ejector in the form of a spring 26 may be provided to direct and insure the proper discharge of a coin from the coin device. I

At 'its rear portion,, and substantially from its rear end to a point midway of the length of the coin-slide, the latter is reduced in width to provide a rearwardly-facing stop shoulder 21 which functions, at predetermined times, to arrest the forward movement of the slide. Cooperating with this stop shoulder are one or more latch means which are disposed at diflferent points along the path of travel of the slide 1 5 and which are normally urgedin that path intoabutting relation with that shoulder, so that unless the latch means have been released prior to the slide: shoulder encountering the latch means, the further advance of the. coins-slide is prohibited and 'it is only possible to properly advance the slide to its coin-di charging position in register with the-opening 24 when such latch means have been released and withdrawn from the longitudinalpath of the stop shoulder 21. By way of example, I have shown two of such latch means, one

At its forward end the slide has the preferably consisting of a horizontally-swinging lever 28 pivoted at 29 to the guide member, section i9 and normally urged at its free end into the path of the slide-shoulder 21 by a spring 30. The other latch means consists of a similar lever 3| pivoted at 32 to the upper section 20 of the guide member and has a spring 33 normally urging its free end into the path of the slide-shoulder. The second-named lever 3| is disposed rearwardly of the first l ver 28, the latter acting to arrest the coin-slide at the first stage of advancement should other than a genuine coin be inserted in the slide and the lever 3| acting to arrest the slide at the second stage of advancement should it pass the first stage when other than a genuine coin is inserted in the slide. The latch means consisting of the levers 28 and 3| are each provided with a tappet portion or pin 34 which is disposed in the edgewise or marginal path of travel of the coin, and should a proper or genuine coin be inserted in the coin slide, then the'peripheral edge of such coin will act at a predetermined time to rock the latch lever, through such pin, in a direction to release it from its normally latched position, and thence allow the coin slide to be advanced properly through the first and second stages heretofore recited. When other than a genuine coin is so inserted, the latching levers will not be released and proper advancement of the coin-slide is prevented.

Means are provided in the operating path of the coin and coin-slide to effect a tilting or displacement of spurious coins or slugs in such a manner as to displace them, at predetermined timesfout of the plane of the lever-pins 34 so that the respective levers 28 and 3| will not be released from their latched positions when an attempt is made to pass other than genuine coins through the device, thereby preventing the forward advancement of the slide beyond a predetermined point. To this end, such means are disposed at two points or stages in the movement of the coin slide and one of such means,

say at the first stage, acts on the one or top side' of a spurious coin to tilt it clear of the tappet-pin 34 of the first-stage latching lever 28, while the other of such means is disposed at the second stage of the coin-slide movement and acts on the opposite or bottom side of such spurious coin to tilt it clear of .the tappet-pin 34 of the secondstage latching lever 3|. Inasmuch as the first and second stage coin-tiltimg means are identical in construction, a description of one will suffice for both, and by preference, each of such mean is constructed as follows: Mounted on the coin slide body 5 and rearwardly of its attaching plate l6, and disposed at that side of the coin slide facing the open side of the coin-aperture l8 for receiving therebetween the marginal or chordal portion of a coin inserted in the coin-slide, are opposinggripping members or jaws 35 and 36 which receive the coin in the manner shown in Figures7, 8, 11 and 12. The jaw 35 is in the form of a flxed'bearpanion jaw members disposed at. the first stage of movement of the coin-slide are borne by the lower section IQ of the slide-body, while the jaw members disposed at the second sta e of movement of the coin slide are borne by the upper section 20 of the slide-body, as shown in Figures, 7, 8 and Figures 11, 12, respectively. A spring 40 coiled about the attaching bolt 31 of the movable jaw 36 and bearing against such jaw normally urges it toward the companion fixed jaw 35. As shown in Figures '7 and 11, those portions or faces of the guide member sections l9 and 20 immediately surrounding the movable jaw-attaching screw 31 are slightly inclined out of the horizontal and the bearing face of each companion fixed jaw is inclined in the reverse direction, whereby, in the normal position of the companion jaw, the movable jaw is slightly inclined in a direction opposite to the facial plane of the fixed jaw, as seen by dotted lines in the aforesaid figures. Furthermore, the leading edge of each movable jaw is beveled to facilitate the entrance of the coin therebetween as the coin-slide'is advanced, and the trailing edge of the said jaw may be likewise beveled to facilitate the egress of the coin, as indicated at 4| and 42, respectively. By this jaw structure, the opposing faces of the jaw members 35 and 36bear firmly on the opposing marginal faces of the coin with the movable or springpressed jaw 36 bearing at an angle to the horizontal on the opposing edge of the coin in the manner shown diagrammatically in Figure 13, 1

whereby this spring-pressed jaw acts in such a manner as to have a tendency to tilt or displace a spurious .coin or sing to such a position that it is out of the plane of the actuating tappet 34 of the companion latch lever 28 or 3 I. When a genuine or minted coin is inserted in the coin slide and it encounters the jaws 35 and 36, the pressure.

of the movable jaw 36 has no effect thereon to tilt it or displace it out of contact with the latchlever tappet, with the result that the coin acts to release the latch lever so that the coin slide may be properly advanced its full stroke to the point of discharge. This fulcruming action imparted to spuriouscoins by the jaw structure described is due to the fact that the structural make-up of such coins presents a curved or rounded edge of such magnitude as to effect the tilting of the spurious coin in the manner above described when encountering the angular pressure of the movable jaw 36. This inherent structure of spurious coins is due to the fact that they are usually stamped or punched was to be made and sold cheaply, while genuine coins are minted and their edges are comparatively sharpedged and of not such a rounded magnitude at their edges to have any effect or tendency to tilt when encountering the jaw structure of this device.

In order to insure the coin being directed into proper engagement with the companion jaws 35 or 36, I provide a suitable deflector 43 arranged in the side of the channel of the slide-body I5 to laterally direct the coin as it approaches the jaws into firm contact therewith. This deflector also functions at a predetermined time to rehave the coin from frictional engagement with the coin-slide aperture, so that when a spurious coin is subjected to a tilting displacement it will be free to do so without interference.

In passing from the first stage to the second stage of movement of the coin slide, I provide a vertically swinging positioning element 44 which is pivoted at 45 to the bottom of the lower body section l9 and whose free end projects through 7, an opening 46 in the latter at a point rearwardly plane of a passing coin and acts normally to force the coin upwardly against the top wall of the guide channel and properly support it while pass ing through the second stage of presentation to the next set of jaw members. ing on this positioning element tends normally to swing it upwardly to perform its function and during the first stage of movement of the coin slide this positioning element is held downwardly below the plane of the coin, as shown in Figure 6, by aninclined shoulder or projection 41 which projects upwardly through an opening in the body section l9 and normally abuts against the underside of the coin slide, that is, in the retracted position of the latter shown' in Figure 1 and in the first stage advancement of the coin slide A spring 44 actdiately upon passing such second stage the lever 44 is deflected downwardly by the bottom of the coin slide so as not to interfere with the final advancing stroke of the coin slide to its position for discharging the coin. The free end of the positioning element or lever 44 is provided with "an upwardly-facing. shoulder 49 so that should a.

washer-type slug be attempted to be passed through this device, the said element will, at a predetermined time, swing upwardly into the opening of that type slug and thereby lock the slide against movement, making it necessary to then retract the slide and informing the user that such a slug will not be accepted by this device.

It will be understood from the foregoing, that when a spurious coin is attempted to be passed through the coin slide, it will be impossible to advance the coin slide its full operating stroke, and that if the spurious coin is not tilted at the first stage of movement of the slide, but will for some reason engage the tappet pin 34 of the first lever all 28 and release it to enable the slide to be moved 7 to its second stage, it will subsequently encounter the next or second stage tilting means and be accordingly displaced where-it will have no efiect to release the second stage lever 3|. When the coin slide is so, arrested, it is necessary to then withdraw the coin slide to its initial position and should the user want service rendered at the apparatus to which the coin slide is attached, he will understand that hemust use a proper and genuine coin. v

In the drawings, a genuine coin has been indicated by the numeral 50 and a spurious coin .by the numeral 5|.
