6 Claims. i (Cl. 1911-101) This invention relates to coin slides used in connection with coin released games o1` vending machines.

The primary object ofl the'invention is to provide a simple, inexpensive, vfoolproof coin slide which will release the associated coin controlled game, vending machine, or other mechanism, only when an authorized coin is handled by the coin slide. If an unauthorized coin is used the slide will not release the associated mechanism and the unauthorized coin will be ejected inside the box containing the coin released mechanism where the slug or the like is removed from circulation and possible further attempts to use the Z Same.

The general object of the invention is to prevent the slide from releasing the associated mechanism when coins not having the required char- A acteristics of value, thickness, diameter, and

composition, such as requisite metal, are attempted to be passed through the slide. Also it is intended to prevent use of coins having an aperture, as certain perforated or apertured foreign coins.

Briey, the coin slide is conventionally mounted horizontally in the wall of a game or the like, said slide being accessible outside the game box to receive a. coin in a coin pocket provided therein for that purpose, while the foolproof coin handling mechanism of the slideis inside the game box inaccessible to the player. Theslide is slidingly supported in a stationary guide to cause the slide to move along a straight line. If the coin is of the proper sizelit can be slid into the game box by the slide and providing it is nonmagnetic such as our standard ve cent piece, which we will here consider to be the authorized coin, the slide can then be pushed home to its innermost position to effect release of the coin controlled mechanism. It is to be understood that the associated mechanism can only be released or unlocked when the slide has been moved substantially the full distance of its stroke into the cabinet or box containing the mechanism to be released. Should the coin be magnetic, a magnet, picks it up at an initial point of movement inward ofy the slide so that no coin is lodged in the coin pocket when inward movement of the slide is continued. When the empty pocket reaches a certain point in its inward travel, a pair ofspring pressed sliding plungers enter the pocket to lock the slide against further movement. When the operator releases his hand from the slide a spring pulls the slide back to its starting position and on the way mechanism is operative to free the coin from the magnet and flip it t0 one side where it falls into the cabinet and is not returned to the player. If no coin is used a single spring pressed plunger is immediately operative after slight movement of the slide to engage the empty coin pocket and lock the slide against fur-, ther inward movement. If a cardboardv disk is employed, this same plunger would bite into the disk and stop the slide. Should an apertured coin be used, this same plunger would be forced into the holein the coin to stop the slide. Such coin, however, would be withdrawn with the slide because `of its lodgement in the pocket where the player could get it back.l So much will suiiice to give a general understanding ofthe purposes and structure of the slide. The invention is illustrated in detail in the accompanying sheets of drawings wherein:

Figure l is a top plan view of the improved coin slide; l

Figure 2 is a side elevational View of the slide; Figure 3 is a bottom plan view of the slide; Figure 4 is a transverse, cross sectional view through the slide as seen in the direction of the arrows along the line 4 -4 of Figure 2 and showing in particular the pin and cam means for ejecting an unauthorized ,magnetic coin from the slide;

Figure 5 is a similar cross sectional view through the slide as seen along the line 5 5 of Figure 1, looking in the indicated direction, and particularly showing the two spring pressed plungers f or locking in the empty coin pocket of the slide to prevent its full inward movement;

Figure 6 is a longitudinal side section through the entire slide as seen along the line 6-6 appearing in Figure 1 looking in the ydirection of the arrows; c

Figure '7 is a cross sectional view through the slide at the line 7 7 'of' Figure 2, looking inthe indicated direction, to show the single, forward spring pressed plunger; and

Figure 8 is a fragmentary plan view of the slide showing a modified form of mechanism for laterally ejecting a magnetic coin. v

For the sake of clearness, the cabinet or box of a game or vending machine, to which the slide is attached, has not been shown; also the mechanism to be released by the slide and its connection with the slide likewise have not been shown, as these things form no partof the invention, and

in any event they are well understood in this art and therefore unnecessary to a complete understanding of the invention. v c

In the drawings, as shown, the slidecomprises a plate 10 having alscrew tapped boss 11 forsecurement in the desired way to a wall of the cabinet, said plate having formed therewith a horizontal guide 12 extending in front of, as well as in back of, the plate 10, it being understood. that the portion of the guide rearward of the plate is inserted through a suitable slot in the cabinet wall closed bp the plate. Thus the major portion of the guide and all of the foolproof mechanism carried thereby, presently to be described, are located within the cabinet inaccessible to the operator. The guide 12 is thus stationary and rigidly mounted.

This guide 12 presents a flat horizontal surface as shown in Figures 1 and 3 formed outside or forwardly of the plate 10 with a small finger hole 13 and at an inner intermediate point with a larger coin drop hole 14. Outside the plate 10 the guide is depressed along its longitudinal median line as shown in Figures 3 and 6 to provide a longitudinal guide groove 15 which is continued as shown behind the finger hole 13 into the plate part of the structure. The rear, or inner end, of the guide, in which the coin drop hole 14 is formed is depressed and at its rear or inner end carries on its top surface a stop block 16 securely held in place by a screw bolt 17 or other suitable means. A spacer 18 is laid on the guide surface as shown in Figure 6 between its channeled edges, said spacer plate being held in place by four screws 19 as appears in the bottom view in Figure 3. This spacer plate 18 is stationary and formed with a coin drop hole 20 in registration With the hole 14 heretofore described. The midportion of the guide framey just back of the plate 10 is open at 21 to save metal, such opening being relatively narrow so that a coin can be passed thereacross, by the hand pushed slide next to be described.

This slide is an elongated flat strip 22 resting slidably and horizontally on the guide surface and between its channeled edges, said slide 22 having a bent handle end 23 for ease of manipulation. This slide is longer than the guide and passes inwardly through the plate 10, over the spacer plate 18 on which it slides, and back to a point beyond the inner end of the guide frame. At Vits rear end the slide carries at its bottom a pin 24 to which is connected one end of a spring 25, said spring having its other end anchored to a pin 26 carried by the under side of the guide frame 12 adjacent the opening 21 as shown kin Figure 3. It will be understood after the slide is pushed inwardly the spring serves to return the slide to normal startingk position when released by the operators hand.

At its forward end the slide 22 has a coin receiving pocket or opening 27 of the proper size, said opening 27 normally, or in the starting position ofthe slide being directly over the finger hole 13 in the guide. Further, the coin hole 27 is larger than the finger hole 13 'so that the coin will be supported in the pocket by the guide and cannot fall through. Forwardly of the coin pocket opening 27 the slide has a central, longitudinally disposed short depression to form a nib or boss 28 that fits down and slides in the groove 15 to guide the slide in its longitudinal slidingI movements.` Just to the rear of the hole 27 the slide carries a downwardly extending guide block or pin 29 moving through the guide groove 15 formed in line with the plate 10 as shown in Figure 6. Just rearwardly of the pin 29 the slide carries an upstanding pin 30 for a purpose later to appear.

Looking at Figures 2 and 7 it will be seen that a cross plate 31 is fastened to the side of the guide frame 12 while on its opposite side the guide frame has fastened thereto an upstanding block 32 intertted with the cross plate 31 to hold the same securely in place, said plate or bar 31 being spaced above the slide 22 to permit the same to slide freely between said plate 31 and guide 12 as will be understood. Along its longitudinal median line the underside of the plate 31 is formed with a groove 33 in which the pin 30 moves. In a vertical bore 34 formed in the bar 31 between its ends, is a centrally disposed plunger 35 having a lower beveled edge 36, said plunger being pressed downwardly by a fiat spring 37 carried by the block 32, as shown.

Between the lightener hole 21 and the coin drop hole 14 the underside of the guide frame 12 carries a second cross bar or plate 38 as shown in Figures 3 and 5, said plate 38 being securely fastened at its ends to the edges of the guide frame. A block 39 is secured to this plate mid.- way between its ends, said block having secured thereto, as shown, a transverse flat spring having curled ends 40 engaging and pressing upwardly a pair of plungers 41 similar to the plunger 35 heretofore described. These plungers 41 each pass up through bores formed in the guide 12 as shown in Figure 5 and are spaced so that when the empty coin hole 27 is in line both plungers are pressed into the empty hole and engage the same at transversely diametric opposite points, while the first plunger 35 engages said empty hole along the longitudinal diametric line of the hole.

As shown best in Figures 1 and 5 the top edges of the guide frame 12, above the plate 38 carry a plate 42, fastened to the frame by screws, said plate, as shown providing shoulders 43 at each edge between which is arranged, flatly, a magnet 44 held down by a clamp device 45. The legs of the horseshoe magnet extend forwardly toward the plate 10 a substantial distance beyond the front edge of the plate 42 and above the open guide frame and the slide 22 so that in the event a magnetic coin is advanced by the slide to this point, the magnet legs are instantly operative to pick up and catch such coin. Centrally and longitudinally the under side of the vplate 42 is lformed with a groove 46 through which the central pin 30 on the top side of the slide guides and passes when the slide is moved that far.

The longitudinal central portion of the slide 22 from the pin 30 back to a point near its rear end is formed with a slot 47 the end of which in the starting position stops against the block 16, said slot guiding along the sides of said block as shown in Figure 1. Thus the block 16 serves to limit t-he forward sliding of the slide under the influence of the spring 25.

It Awill be remembered as an object of the invention that it was desired to eject magnetic coins and slugs laterally out of the slide and into the cabinet where the operator could not retrieve his coin. Accordingly, the rear edge of the cross plate 31 is formed as a wedging cam edge or surface 48. The pin 30 heretofore described is behind a magnetic coin or slug held by the magnet andas the spring 25 returns the slidefo-rwardly to its starting position the pin 30 pushes the coin forwardly to release it from the magnet and force it against this cam edge 48 and because of its receding curvature, and the fact that the coin is circular, the coin is ejected laterally out of the slide. In the event that the central pin 30 fails to accomplish this function alone, a second offset pin 49 is'mounted on the slide.` Said pin 49 is offset from the pin 30 in the direction of movement followed by der side of the plate 43 to accommodate thepin- 49 as the slide is moved. The operation and use of the slide under varying conditions will now be described.

First we will assume an authentic coin, such as the five cent piece is employed. The coin is placed in the pocket 27 and thereupon the operator grasps the handle 23 and pushes the slide inwardly against the force of the spring 25. As the pocket 27 with the coin therein presents a flat surface it rides under the yielding front plunger 35 which is thus made inoperative by the presence of the co-in. Similarly as the slide advances the pocket and coin, the latter rpasses by the magnet and the two rear plungers 41 which cannot function to stop the slide when a coin is in the pocket. As the coin moves along it finally reaches a position directly over the registering coin drop openings 20 in the spacer 18 and 14 in the guide frame. Thus the coin drops through, free of the slide, and as the slide has now advanced the full stroke, the associated game or vending mechanism is released or un,- locked. The user now releases his hand from the slide and the spring is `operative to return the slide to its initial starting position.

Should an attempt be made to Apass a magnetic coin or slug, the magnet 44 is strong enough instantly to pick up the coin as it movesl out from under the plate 31 and raise it to a position above the slide so that the slide continues inwardly with an empty pocket 27. When the empty pocket passes over the two plungers 41 they are spring pressed into the empty hole 27 to lock the slide against further inward movement. Thus under such conditions the slide cannot be advanced a full stroke to release the coin controlled, associated mechanism. Again, when the operator releases the slide, the spring 25 pulls it back and the spring pressed plungers 41, which have wedge-shaped lower ends, merely ride out of the hole 27 in a. manner that will be'readily understood. The supplemental pin 49 assists in ejecting the coin.

If it is attempted to move the slide in without any coin in the pocket 27 then the front plunger 35 is immediately pressed into the empty hole 27 to lock the slide.

If a cardboard disk is played, then the front plunger 35 again immediately is pressed into and scores or perforates the disk to lock the slide against furthen movement.

If a coin having a central aperture is played then again the front plunger 35 is forced thereinto to lock the slide against further movement. Such coin can only be moved as far as the plunger 35 and when the spring 25 pulls the slide back, such coin is returned to the player because it is pocketed in the hole 27 and must move back with the slide. 'Ihe coin is removed by inserting a finger upwardly through the finger opening 13 in the guide frame.

In Figure 8 an important modified form of means for laterally ejecting a magnetic coin is shown, the main slide parts being shown and numbered the same as in the other views. However, in this modication the pins and 49 are eliminated and a spring pressed, guided hook member issubstituted therefor, such hookv member serving as a positively acting; strikerwhich engages and positively forces the magnetic coin laterallyv out of the slide. As shown in Figure 8V a post 51 is carried on the top side of the slide 22 adjacent its rear or inner end, vsaid post pivotally carrying a forwardly extending mem.- berY 52 having a hooked inwardly extending end 53, as shown. 'Ihe member 52 is normally pressed into the full line vposition shown bya spring 54, said hook 53 then lying inthe space between the cam edge 48 and the forward edgel of the plate 42, said plate 42 having a rounded guidev corner V55 in this Aform of the invention..

The edge of the guide frame is cut away atk 56 to provide a passage for movement of thehook,

53 in rand out in relation to the slide. A guide plate 57 isy welded to the adjacent side of ,th frame 12.

In use a magnetic coin is moved inwardly by the slide until themagnet 44 picks it up. In the meanwhile such inward strokey of the slide 22 carries the hooked element 52 with lit causing thej hook part 53 to be forced laterally out ofthe. slide, as it guides over the rounded corner 55. The end of portion 53 then rides over they guide 57 aS` shown in the dotted line position of Figure 8.- The empty coin pocket next receives the plungersA 41 to lock the slide against further movement.

When the slide is released bythe operator a it strikes, hammer fashion, against the trapped,

coin and positivelyejects the same from the magnet and slide in an obvious manner.

From this detailed description it will now be seen that an improved coin slideor chute has been provided which achieves heretofore recited.

It is the intention to cover herein all such changes and modifications of the preferred form selected for this disclosure, which donot in material respects depart from the spirit and scope of the invention.
