Patented Mar. 4, 1941 UNITED STATES vPli'rrfzNT OFFICE 12 Claims.

'I'his invention relates to coin-freed control mechanisms commonly referred to as coin slides, and has among itsimportant objects the provision of an improved frame structure, slide mechanism and operating means therefor, together with novel fraud-preventive devices cooperable with the slide mechanism, and also an improved form of discharge chute.

More specifically stated, one of the important objects of the invention is the provision of a guide frame having a coin-receiving or deposit opening and a discharge opening spaced therefrom, a coin slide mounted for reciprocable movement in the frame, and manually operable push bar mechanism for reciprocating the slide so as to move a coin-receiving pocket in the latter from the coin deposit opening toward the discharge opening in the frame.

A further object is the provision with a slide frame of the type just described of a drop-out pocket adjacent the deposit pocket in the frame and into which a coin deposited, after the coin slide has been moved in, will be moved by the slide upon its return stroke to be returned to the depositor.

Still another object is the provision of fraudpreventive means in the form of a cut-off pawl arranged to be positively cammed by the coin slide for movement into position behind the end of the slide after the latter has moved a predetermined distance in its operating stroke.

Yet another object is the provision of fraudpreventive means in the form of a gauge dog structurally related to the aforesaid cut-oil? device or pawl and operable to latch the slide.

against movement responsive to engagement by this gauge pawl with a coin of improper thickness.

Yet another object is the provision of a discharge chute and auxiliary slide means cooperable with the main coin slide for regulating the movement of coins into the discharge chute, the latter being provided with pawl mechanism adapted to sweep coins released from the auxiliary slide means and move such coins step by step along the discharge chute.

Other novel aspects of construction and operation of the invention reside in the form and arrangement of parts to be hereinafter particularly described and claimed in view of the annexed drawings in which:

Fig. 9 is a fragmentary vertical section duplicating parts of Figs. 8 and 5 and showing the pawls and slide in full operative position; while Fig. 10 is an enlarged perspective detail of a portion of the discharge chute and discharge pawl mechanism.

In general the novel coin slide unit includes, as viewed in Fig. 1, a main frame in the form of a horizontally extended casting having a vertically extending mounting plate or wall I2 dividing the frame into a front or depositing section I3 and a rear section I4 in which is slidably mounted a main coin slide I5 having a pair of spaced coin apertures I6 and I1, the former being situated close to the front or left-hand extremity of the slide and being normally disposed in registration with a coin deposit opening I8 in the front section I3 of the main frame. Operating mechanism including a push bar or actuating slide I9 is provided to reciprocate the slide I5 so as to move a coin, deposited through the depositing opening I8 into the slide pocket I6, beneath the mounting plate I2 and past certain fraud-preventive dogs toward a discharge opening (Fig. 5 also) situated below the normal position of the innermost or right-hand coin-viewing aperture I1 in the slide I5. Secured to the main frame so as to extend therefrom in a lateral direction is a discharge chute 22 provided with mechanism, operable by actuation of the slide, for moving coins in step by step fashion toward the discharge end of the chute.

As viewed in Figs. 3 and 5, the slide actuating mechanism I9 includes a pair of spaced push rods 23 and 23' joined at one end by the push member I9 and at their opposite or inner end by a cross bar 24 suitably secured to the inner ends of the rods. The spaced rods 23 and 23' are slidable in the lower portion I2 Qf the vertical mounting plate or wall I2 and also in staggered lugs 25 depending from the inner body of the frame. A coil spring 26, anchored at one end 21 to the frame and attached at its opposite end 28 to the cross bar 24, normally urges the push bar actuating member I9 into its normal position, as viewed in Figs. 3 and 5.

At its rearward end, the main coin slide I5 is rigidly connected to the push rod structure I9 by means of an angled extension 29 of the cross bar 24 which is secured to the slide by the pin means 30. As before stated, the slide I 5 is seated in grooved formations 3| (Fig. 2) in the main rear frame extension I4 and is slidable through an opening 32 in the mounting plate I2 into a grooved portion of the forward extension I3 of the frame, so as to position the coin-receiving or depositing hole I6 in slide I5 beneath the coin depositing opening I8 in the frame, this latter condition being represented by the normal dis-` on which the deposited coin rests to be carriedv with the slide I5 inwardly when the latter is moved by the push bar structure I9.

Formed in the underside of the front ledge extension I3 of the frame is a novel form of drop-out opening 34 communicating with the deposit opening I8 interiorly of the casting (see also Fig. 3), and extended from the juncture of the drop-out opening 34 with the depositing pocket I8 is an elongated slot 35 which leads back through the bottom ledge portion of the slide seat in the frame into a depressed shelf portion 36 formed in the frame below the slide I5 and onto which a coin will gravitate out of the aperture I6 in the slide when the latter is moved inwardly. At the outer or left-hand end of the slide I5 is a depending ear or lug 31 (Figs. 3 and 5) which moves in the elongated slot 35 from its normal position, as viewed in Fig. 5, to the full stroke position as viewed in Fig. 9, the purpose of this lug -being to engage the edge of a coin 38 as it falls onto the shelf 36 out of the pocket in the slide so as to shove the coin along toward the discharge opening 20 in the frame to the rear or at the right of the shelf 36. There is also provided a depending lug 40 positioned on the opposite side of the coin opening or pocket I6 in slide I5 and extending into the elongated frame slot 35 so as to block the latter against the insertion of fraudulent operating devices, such as wires and the like, when the slide is in its normal position.

Extending longitudinally from the front coin .pocket I6 in slide I5, is a slot or channel 4I which communicates with the rear sight opening I1 in slide I5 and which also has an extension 4I' projecting somewhat beyond the rear opening I1 (Figs. 1, 2 and 7).

Slidably mounted below the rear extension I4 of the main frame is a. reciprocable auxiliary slide 39 having a coin discharge opening 39' through which a coin moving into the discharge opening 20 may descend onto the floor 42 of a discharge chute later to be described in detail.

The auxiliary slide 39 has a depending lug 43 to which is attached one end of a spring 44 anchored on an ear 45 attached to the discharge chute 42 `(Figs. 3, 5 and 9) whereby the auxiliary slide is normally urged toward the left and into a normal position as seen in Fig. 5 wherein the opening 39 thereof is in register with the sight opening I1 in slide I5.

However, when the coin slide I5 is moved into its full stroke position as seen in Fig. 9, the auxiliary slide is moved therewith so that a portion 39" blocks the discharge opening 20 in the frame and serves to hold a coin 38 therein until the main coin slide is returned to normal position. This is accomplished by means of a pin 46 which projects upwardly from the rear of the auxiliary slide A39 into the rearward extension 4I' of the longitudinal slot 4I in the main slide I5, there being a shoulder formation 41 (Fig. l) at one side of this slot or channel which bears against the pin 46 when the slide is moved inwardly a predetermined distance, so that thereafter the main slide and the auxiliary slide move together for the remainder of the stroke.

Slidably mounted on the floor of the discharge chute casting 42 (Fig. 10) is a coin-feeding cam 48 pivotally connected as at 49 (see also Fig. 9)

to the auxiliary slide 39 for movement with thelatter. I'his feeding pawl 48 has an irregular slot 59 formed therein and in which is received an upstanding pin 5I on the oor of the chute 42 and which is effective, when the pawl is moved back and forth with the auxiliary slide 39, to pivot the pawl back and forth about the pivotal point 49 so as to cause the nose portion 52 of the pawl to sweep back and forth from the dotted line to the full line position illustrated in Fig. l0 for the purpose of sweeping or pushing a coin 38 lying on the floor of the chute 42, onto which it has been previously discharged from the discharge opening 29 in the main frame, toward and past a plurality of presser fingers in the form of springs A53 attached to the bottom of the discharge chute 42 and protruding into the chute through bottom wall openings 54.

'Ihe chute generally indicated at 22 in Figs.-

1 and 3 includes the main frame portion 42, above referred to, and which is adapted to be removably attached to the bottom of the main guide frame by screws or other suitable means 55. This bottom member of the discharge chute is preferably in the form of a die casting and has an elongated coin channel 56 formed therein communicating with an enlarged head portion in which the sweeping or feeding pawl 48 is seated, at the point where the presser fingers 53 are situated. At the opposite end 51 of the discharge chute,

- the coin channel 56 is open so that coins may pass from the latter into any desired receptacle. Intermediate the end 51 and the head portion of the chute is an elongated drop-out opening 58 through which coins of less than a predetermined dlameter are intended to pass for rejection. Still referring to Fig. 1, it will be seen that there is provided a U-shaped presser member 59 having its opposite side arms 60 seated in slots formed in the side wall portion of the chute extension 22, the ends 6I of these arm portions being bent back toward one another to prevent the disengagement of the presser from the slots. Between the inner surface of the presser 59 and the opposite wall portion of the chute body is a spring 62 which normally tendsvto project the main body of the presser into the channel portion 56 of the discharge chute and slightly beyond the edge of the drop-out opening 58; thus proper coins or tokens will be carried over the drop-out opening 58 by the suspension of the coin in yieldable pressing engagement with the presser bar 59 and the opposite wall of the chute passage,

while improper coins or tokens of less than a .determined diameter will drop directly through the opening 58. It will be apparent that a plurality of coins 38 (referring now to Figs. 1 and 10) will collect in the chute 22 between the discharge end 51 and the head portion thereof Vand that as each coin 38 drops onto the floor of the discharge chute the pawl nose 52 will move the coin into the chute proper, each subsequently deposited,coin engaging the one previously deposited and serving to move the latter along in step by step fashion. 'I'here is further provided a cover plate 63 forthe chute extension 22 and attached to the latter by means of screws 64. This plate has an elongated opening 65 through which the coins distributed in the chute may be viewed.

The important fraud-preventive means provided by the invention includes a cut-off dog or pawl 10 pivotally mounted as at 1| (Figs. 1 and 7) on the frame above the slide I5, and having a depending nose portion 12 substantially of the same width as the slide and disposed laterally across the path of movement of the same. Formed beneath the slide I5 in the main frame and behind or to the right of the mounting wall I2 thereof is a lateral recess or depression 13 into which the laterally extending nose portion 12 of the stopping dog descends when the slide I5 has been moved in full stroke position as illustrated in Fig. 9 so as to completely block the opening 32 in the wall portion I2 and cut off any access to the mechanism through the deposit opening I8 and the wall I2.

The cut-off or stopping dog 10 is normally urged by means of a spring 14 into lowered position with the lateral depending nose portion 12 thereof in a normal position bearing down on the slide I5, notches 12' being provided at opposite extremities of the nose edge 12 so that the latter may t closely down between the longitudinal side flanges of the slide. The pawl 10 is provided at its end opposite the nose portion 12 thereof with a cam portion A15v overlying a side edge portion of the slide I5 and engageable by a cam rise or ange 16 on the side of the slide when the latter is moved a predetermined distance inwardly, that is to say a distance corresponding closely to the approach ofthe outer axial end portion of the slide I5 (at which the depending lug 31 is situated) just beneath the depending nose 12 of the cut-off pawl 10, the cam portion 16 on the slide by its engagement with the cam extension 15 on the pawl serving positively to pivot the pawl forcibly downward so as to cause the nose 12 thereof to descend over the retreating edge portion of the slide I5 as the latter moves into full stroke postion, thereby completely blocking any access to the operating mechanism through the opening 32 in the frame.

The cut-01T pawl 10 is substantially constructed, and the mechanical advantage in the cam arrangement is such as will provide a considerable leverage so that should any device such as a wire or feeler ribbon or the like be attached to a coin or be inserted in the slide or lie in the path of the descending movement of the nose 12 of the pawl, the force of descent of the latter will be adequate in most instances to shear the feeler or wire, or substantially deform the same so as to render the fraudulent attempt wholly unsuccessful, in addition to preventing any further possibility of access to the mechanism so long as the pawl remains cammed in blocking position by the slide I5. As soon as the slide I5 is retracted and the cam rise or flange 16 passes out of engagement with the cam 15 of the pawl, the latter willbe urged by the spring 14 back into the position wherein the cut-off dog 10 bears down on the slide I5; and when the slide I5 is likewise in normal position, the depending ear 40 thereon will adequately block the passage 32. It will also be observed that'the pawl 10 must be moved into effective position whenever the slide I5 is moved a predetermined distance, regardless of whether there is a coin in the slide or not.

A further fraud-preventive mechanism is provided in the form of a gauge pawl 11 (Figs. 1, 6, and '7) pivotally mounted as at 18 on the frame above the slide I5 adjacent the pawl 10. This gauge pawl has an angled end portion 19 from which depends a finger positioned above the slide I5 in the path of movement of the coinreceiving or bearing aperture I6 thereof, so as to engage a coin in the latter as the slide is moved inwardly, and this finger 80 extends downwardly in a slot 88 cut in the pawl 10 between the nose portion 12 and the pivoted side of the same. Likewise depending from the main body portion of the pawl 11 is a latching finger 8I which is movable into an edgewise slot 82 formed in the longitudinal edge of slide I5 at one side of the coin opening I6. The gauge pawl or dog 11 is normally urged in a descending direction toward the slide I5 by means of a spring 83, and if there is no coin in the opening I6, as the slide moves the latter beneath feeler finger 80, the pawl will be pivoted downwardly by the spring 83 to project the finger 8| thereof into the notch 82 of the slide and prevent the further inward movement of the latter. It may be observed that the lower extremity of the feeler finger 80 lies in alignment with the longitudinally extensive opening or slot 4I in slide I5, thus providing for free movement of the slide while at the same time the nose of the feeler 80 may descend the required distance into the opening I6 should there be no coin in the latter.

A further fraud-preventive instrumentality is provided in the form of a permanent magnet 84 mounted by bracket means 85 on the rear frame section I4 with its pole faces arranged above the slide I5 close to the opposite edge portions of the coin opening I6 so as to attract a magnetic token in the latter and raise the same from the slide a distance adequate to cause the advancing edge of the coin so raised to bear against a depending lug 86 just above the free edge of the shelf 36 in the frame, and thus lock the slide against further effective movement.

Having thus illustrated my invention by describing in detail a preferred embodiment and arrangement of parts in realizing the several objects heretofore recited, it is to be understood that all equivalent constructions, modifications, and variations of the foregoing particularly described structure are intended to be embraced by the appended claims.
