19 Claims. (Cl. 194-97) This invention relates to coin slides and has Coin slide, in that the embossed pocket of the for its object to provide a construction simple in prior application has been replaced by a yieldparts and more eflicient in operation than those able member which prevents clogging of coins in heretofore proposed. the discharge opening of the coin slide guide.

S. Letters Patent filed Novemguide contiguous to the linger hole 10. ber 5, 1931 under the Serial No. 573,173 entitled The bottom wall of the guide is also provided 110 with an opening 12 located on the inner side of the face plate 1, the width of this opening being slightly less than the diameter of the proper coin so that if a coin of lesser diameter is used in a fraudulent attempt to operate the device, the smaller coin will drop through the opening 12 upon an inward movement of the slide. At the inner end of the guide beyond the opening 12 there is a third elongated opening 13 in said bottom wall constituting a slot for receiving and discharging coins which have permitted the full intended inward movement of the slide. The outer end of this opening is normally covered by a trapdoor described hereinafter, while the inner end 14 is circularly formed and uncovered to constitute the discharge opening through which coins may drop into any suitable collecting means not shown but understood.

On the upper portion of the guide and in the central longitudinal plane of the slide, there is mounted a dog 15 pivoted at one end as at 1d in brackets 17 carried by a bridge 18 extending across the upper side of the guide, said bridge being suitably apertured to permit said dog to move therethrough under the urge of the leaf spring 19. When the slide containing no coin is moved inwardly the point of the dog will ride on the upper surface of the slide and then be forced by its spring to extend into and through the coin receiving aperture 11 and jam against the edge of the coin opening, preventing further inward movement of the slide. On the other hand, if a proper coin is in the slide, the dog will be kept elevated by riding over the upper surface of the coin, and thus permit the slide to travel further inward with respect to the cabinet.

The bottom wall of the guide is provided with a pair of opposed brackets such as 20 for supporting a pin 21 upon which are pivoted two

dogs

22 and 23 disposed on opposite sides of the longitudinal center line of the slide, as clearly shown in Fig. 3. These dogs are spaced by a sleeve 24 and are urged upwardly against the bottom surface of the slide by virtue of a double wound coil spring 25 the ends of which engage said dogs as shown. Suitable slots are provided in the bottom wall of the guide through which the

dogs

22 and 23 may pass. By thus providing a pair of spaced dogs below the slide and a single dog above the slide intermediate said pair, at least one dog may engage openings in coins, tokens, or washers which are not acceptable for use in operating this slide.

The coin slide 5 is provided with a longitudinally extending slot 30 into which extends an abutment member 31 secured to the guide as by the screw 32. As best seen 'in Fig. 2 this abutment member lies in the plane of the slide, but one end of said member is bent U shaped in order to provide a portion adapted to lit, and be secured to, the guide, and the juncture of this U-shaped portion with the portion lying within the slot of the coin slide provides a shoulder 33 which serves as a stop for limiting the outward movement of the slide. In other words, when the slide is moved outwardly the innermost end of the slot 30 thereof comes in contact with the said shoulder and prevents further movement of the slide in that direction. The slot 30 is extended through the coin receiving aperture 11 as indicated at 34 and the extreme end of the slot portion 34 is adapted to engage the free end of the abutment 31, thereby limiting inward movement of the coin slide. These two limiting positions of the slide are clearly shown in Figs. 'l and 3.

The guide has a yieldable bottom section constituting a trapdoor covering the outer end of the coin receiving slot of the guide, said door normally adapted to lie in a plane spaced from the under surface of the slide a distance suiicient to accommodate therebetween a coin of the proper thickness. This trapdoor comprises a plate 40 whose free edge is circular and has outwardly turned points such as 41 at the corners thereof, which points are adapted to rest upon the outer surface of the guide contiguous the edge of the guide slot 13 as clearly` indicated in Fig. 3. The other edge of the plate 40 has se cured thereto spaced bracket members such as 42 each provided With an elongatedv slot 43 through which passes the pin 21, the bracket members 42 adapted to lie between the brackety members 20 of the guide and the

pairof dogs

22 and 23. The slots 43 are elongated in a direcy tion substantially perpendicular to the planeof the plate 40, see Fig. 12. The spring 25 aforementioned is reversely wound, the middle portion 44 adapted to urge the plate 40 in a direction; toward the coin slide.

Should a coin for any reason fail to pass the plate 40 for release through the c'oin discharge opening 14, as in the case where the coin was thin and/or where from continued slide actuation one or both of the lugs 50 and 51 (presently to be described) were worn, the next inserted coin carried by the slide will not create a jamming with the previously inserted coin because the plate 40 will yield and permit ythe passage of the two superposed coins to and through said discharge opening.

The slide is provided with downwardly extending lugs 50 and 51 disposed in the longitudinal center line of the slide on opposite sides of the coin receiving aperture 1l as clearly shown in Fig. 2, the purpose of these lugs being to move a 115 coin which has dropped slightly below the plane of the slide. These lugs are preferably formed by a die stamping process which angularly bends a portion of the slide downwardly, and therefore there is provided a pocket over each lug, indicated at 52 in Fig. 2, which has been made use of in the fraudulent operation of this device,` as will be pointed out hereinafter. Provision for these lugs is made in the guide in the nature of a channel 53 which extends substantially theentire length of the guide. To illustrate the function of these lugs, a coin of the proper size will be retained in the plane of and be moved by the slide inwardly until the coin reaches the receiving slot 13 of the guide where the coin 130 will tip on the edge of said slot and move downwardly onto the upper surface of the trapdoor. Further inward movement of the slide causes the entire coin to rest on said plate, as indicated in dashed lines at 54 in Fig. 11, and therefore to 135 lie between the plane of said plate and the bottom surface of the slide, but the outermost lug 5l engages the edge of the coin and slides it over said door to the discharge opening 14.

If for any reason the slide is not moved far 140 enough inward to cause this discharge of the coin, and the slide is then permitted to move outwardly, the coin now resting on the trapdoor will be moved by the other lug 50 until the edge of the coin comes in contact with the outermost 145 end of the guide slot 13, stopping further outward movement of the slide. In other words, the proper coin is trapped unless the slide is moved to the full intended innermost limit of its travel to cause the coin discharge, and therefore the lfil only way to release the trapped coin is by shoving the slide clear in.

To prevent operation of the device with a disk of magnetic material such as iron or steel, there is provided the usual magnet disposed immediately above the coin slide, said magnet being of the horseshoe type with its ends disposed between the end of the abutment 31 and the outermost end oi the guide slot 13. It therefore results that a magnetic disk will pass all three of the dogs if it be of the proper thickness, diameter, and is imperforate, but its advancing edge will be attracted upwardly by magnetic force of the magnet and not permitted to drop downwardly onto the trapdoor 40.

In other words, the magnetic disk will be retained in the coin opening 11 and therefore be kept in the plane of the coin slide, and upon further inward movement of said slide the advancing edge of the magnetic disk will strike the end of the abutment 31 and prevent further inward travel of the slide. Because the magnetic disk is maintained in the plane of the slide, said disk may be drawn with the slide to the outermost limit of travel of the latter, thereby permitting recovery of said disk by the operator of the device, and no jamming action will take place in the guide slot 13 as just previously mentioned.

As stated in the beginning of this specification, the coin slide of the prior filed application could be manipulated successfully but fraudulently by the use of a special token, but naturally such a token would have to be capable of being retained in the plane of the coin slide. There has appeared on the market such a special token or key, particularly illustrated in Fig. 10, embodying a disk 56 of the correct thickness and diameter but which is provided with diametrically disposed outwardly extending prongs or points such as 57 and 58 which are adapted to iit in the inclined pockets 52 created by the formation of the lugs 50 and 5l respectively of the coin slide. In Fig. 9 this special but fraudulent disk 56 is shown in position in the slide.

An important feature of this present invention resides in making the abutment member 31 substantially of a length to extend entirely across the coin discharge opening 14 instead of halfway across as disclosed in said earlier filed application. The special token 56, being provided with the slotway 59, would permit fraudulent operation of the device of said prior application because the abutment' member would be easily accommodated in said slotway at the limit of the inward operative stroke of the slide. In this present invention, however, the abutment 31 is too long to be accommodated in such a slotway 59 wherefore the inward movement of the slide is stopped when the end of the abutment contacts the end of the slotway of the fraudulent special token 56. As an additional precaution against fraudulent operation, this present slide must move inwardly to actuate the vending mechanism a distance such that the coin receiving aperture ll of the slide will have passed the coin'discharge opening 14, wherefore the slot extension 34 is provided to accommodate the end of the abutment member 31, as shown in Fig. 8. These features have been particularly illustrated in Figs. 8, 9 and 1l, the last mentioned figure showing in dotted lines the position of the slide handle when the slide has moved to the inward limit of its operative stroke, and showing in full lines the stopped position of the slide while carrying the fraudulent disk 56. Also in Fig. 11 in dashed lines is shown the position of a proper coin or token resting upon the trapdoor 40, but still under the control of the lugs 50 and 51 of the slide for movement thereby in either direction.

It is obvious that those skilled in the art may vary the details of construction as well as arrangements of parts without departing from the spirit of the invention, and therefore it is not desired to be limited to the foregoing except as may be required by the claims.
