4 Claims.

This invention relates to coin testing mechanism and has as its principal object the provision of improved ejecting and scavenging or clearing means for use in a gravity type chute.

More specifically, it is an object of the inventhe same out of the chute when the gate is opened.

Another object is the provision of a gate having oifset formations cooperable with other parts of the chute to provide a. scuttle or funnel-shaped coin entrance to prevent jamming, the gate having a drop-out opening near the coin entrance, and improved feeler means arranged in a particular manner with respect to the drop-out opening and coin entrance.

Another object is the provision of a combination magnetic testing means and gate closing means.

Still another object is an improved sweep arranged for coaction with the gate to dislodge coin elements arrested by the magnetic testing means, the sweep being of a particular form which is efiective to prevent movement of coins other than the dislodged coin element down the chute or toward the magnetic testing means so that the chute cannot be deliberately jammed, and all coin elements behind the one arrested will be discharged from the chute.

Yet another object is a simplified mounting means for a discharge chute arranged also to define a portion of an acceptance passage in the chute.

Other objects, advantages and economies residing in the invention pertain to certain details of construction, arrangement and operation of the parts described hereinafter in the specification of the preferred embodiment, and in view of the annexed drawings in which: I r

In the illustrative. embodiment of Fig. 1, the chute includes a main mounting plate l0 having laterally ofi'set ears ll along its upper'edge which constitute mounting lugs for a discharge gate I2. This gate is made from a metal plate'lo (Fig. 6) having a somewhat V-shaped slot I3 cut in its upper edge with an edge portion of the slot offset laterally to provide a mounting ear I l. The upper edge portion of the gate plate is offset along a horizontal line between its ver- 15 tical edges, and the right-hand (Fig. 1) extremity of this offsetting is further offset laterally to provide another mounting ear IS. A pintle rod I6 is passed through the ears [4 and IS on the gate and the ears H on the chute plate to go suspend the gate for movement toward and away 'from the plate about a horizontal axis extending parallel with the plane of the main plate, and the gate tends to hang in a lowered position in spaced relation with the inner surface 25 of the main plate Hi to define a chute passage.

The left-hand offset I1 adjoining the ear M on the gate, serves, in conjunction with the opposite portionofthe mounting plate to define a funnel or scoop-shaped coin entrance l8, the 30 objects and advantages of which will be mentioned hereinafter. A portion of the gate in and immediately below the offset I! is punched out to provide a drop-out opening IS. A discharge chute in the form of a channel-shaped plate 20 35 open at its. upper and lower ends is secured to the side of the gate and has an oifset upper edge portion 2| constituting a discharge apron disposed immediately below the drop-out opening l9; coin elements from the latter opening 0 are guided through the chute 20' out the lower end of the latter and into a downwardly inclined chute section 22.

The chute section 22 is formed by bending a plate'back upon itself to form a channel of the 45 shape illustrated in Figs. 1 and 3, one side 23 of the channel-forming plate being ofiset and passed through an opening 24 in the main plate to be secured to the outside of the latter by welding or other suitable means, so that the chute section 22 is spaced from the inside of the main plate to define, in conjunction with the latter, an'acceptance passage 25 adjacent the lower reject passage 26 defined by the section 22. The main coin passage 21 is defined u between the inner faces of the gate [2 and the main chute plate Hi, this main passage extending from the flared entrance mouth ll downwardly between the gate and mounting plate along an inclined runway ledge 28 (Figs. 3, 4, 6) arranged on the inner side of the'gate and terminating as seen in Fig. 6 adjacent the juncture of a tail 29 on the gate and opposite and above a rebound anvil 30 (Fig. 1). Coin elements descending in the main passage, after leaving the end of the runway 28, strike the anvil and rebound for movement between the tail 23 and the inside of the main plate l0 into the acceptance passage defined between the innermost face of the chute section 22 and the inside of the mounting plate l0.

An adjustable segregating device is provided in the form of a member 3| (Figs. 2 and 5) having an offset lug portion 32 projected through a horizontally elongated slot 33 near the bot tom edge of the main plate in the acceptance passage 25.

The member 3| is. supported for horizontally adjustable movement by a screw 34 threaded into the member 3|.

the main plate through an elongated slot 35 in The oflset lug portion 32 of the segregator is adjusted to lie in a. particular position in the path of coin elements rebounding from the anvil 30 toward the acceptance passage 25, coin elements of predetermined physical characteristics clearing the obstruction or lug 32 for movement into the acceptance passage and into a suitable collecting receptacle therebelow. Coin elements which do not reboundin the required manner strike the obstruction 32 and fall back toward the anvil in the region opposite the lowermost extremity of the reject passage 26 for return to the depositor.

One of the features of the invention is the improved testing means in the form'of a feeler 40 which is made from a strip of metal having offset mounting ears 4| and an oppositely ofl'set lug 42, adapted to mount an adjusting screw 43, arranged near its upper edge. The feeler is mounted on a pintle rod 44 extended through the ears 4| and ears 45 on a. mounting bracket screwed to the outside of the plate. The lowermost edge portion of the feeler isbent or offset to provide a deflector portion 46 which projects through an opening 41 in the main mounting plate In substantially opposite the drop-out opening IS in the gate, the counterweight screw 43 in fact being adjusted so that the lower edge of the deflector portion 46 will bear against the gate at the drop-out opening and thus form a movable obstruction across the entrance zone to the main passage. A point 48 projects from the lower edge of the deflector portion and extends through the drop-out opening I9 for engagement in apertured coin elements to arrest the same.

Additional testing means includes a. permanent magnet 50 (Fig. 2) mounted on the outside of the main plate by brackets 5| secured at their offset end portions to the latter and clampingly engaging the magnet by a brass screw 52 (Fig. 4) passing therethrough and through the bight portion of the magnet, the latter being of the conventional horseshoe type. It will be observed that the brackets 5| close the magnet off at all points and prevent dust and magnetically attractable particles from working toward the polar extremities of the magnet from the outside of the chute.

The poles of the magnet 50 are situated about aaaae'ra halfway down the main chute passage between the entrance l3 and the anvil 3| and maintain a constant flux across the passage for the purpose of selectively influencing the movement of coin elements toward the anvil so that acceptable coin'elements will ultimately strike the anvil at a certain velocity.

Another feature of the invention is the provision of a combined keeper and gate closing means for the magnet and which includes a magnetically attractable member or block 55 (Figs. 1, 4, 6) secured by spot welding or other means to a mounting strap 56 attached by screws 51 on the outside of the gate, the block 55 resting in an opening cut in the gate so that the inner surface of the blockis substantially flush with the inner surface oi'the gate, the block being positioned exactly oppmite the pole pieces of the magnet 50 so that the field of force extending from the pole pieces is caused to be directed in greater concentration across the passage and through the block 55. This block constitutes a keeper for the magnet which prolongs its life and, in addition to this function and its effect in concentrating the field, it provides an automatic closing means for the gate, since the block is obviously attracted by the magnet so that the gate is normally but yieidingly urged into closed position. 7

Means for simultaneously opening the gate and dislodg ing magnetically attractable coin elements arrested by the magnet 50, includes the provision of an elongatedsweep arm 50 (Fig. 5) pivotally mounted as at El on the inner side of the main plate above the anvil and having an opposite end portion adapted to sweep downwardly past the pole pieces of the magnet 50 to engage and dislodge an arrested coin element from the influence of the latter. 'A spring 62 engaged at one end with an ear 63 on the sweep and at itsopposite end with a lug 64 on thechute, normally raises the sweep out of the path of coin elements as seen in Fig. 5.

The sweep has an angular projection 65 constituting a cam which is positioned opposite an opening (Figs. 1, 2, 5, 8) cut in the main plate the hand or other actuating means to depress V the lever and cause the roller 69 to bearagainst the cam formation on the sweep and pivot the latter downwardly in sweeping action. At the same time the offset 61 engages the roller 86 on the gate and pivots the latter to open position. Thus, the sweep and gate are actuated simultaneously. When eifort is removed from the leverifl, the same will be restored to its normally raised position by action of the spring 62 in its effort to raise the sweep to normal position. And the coaction of the magnet 50 and keeper 55 will positively restore the gate to normally closed position.

In the operation of the device, coin elements are deposited into the scoop-shaped entrance opening I! and strike the deflecting portion 4' of the feeler. If the coin element is of light weight or undersized in diameter, it will immediately pass out through the drop-out opening I8 due to the inclination of the deflector 46, otherwise such coin element thereafter will pass through the reject chute 20-22 for return to the depositor, or be sustained by the feeler until the gate is opened.

If the coin element is of proper weight and size, the feeler 40 will be pivoted out of the way to permit the coin to move into the main passage, provided the coin is not apertured. If the coin is apertured, the point 48 will engage in the apertured portion thereof and arrest the coin.

Assuming the coin succeeds in passing the feeler 40, it will move down the runway 28 into the field of the magnet 50 and be arrested by the latter if the coin element is magnetically attractable, otherwise it will continue down the passage off the end of the runway 28 and toward the anvil 30. If the coin is underweight or if its metallic composition is not that required, the coin will drop more or less directly off the end of the runway in the direction of the tracer arrow of Fig. 5. If the coin is of the acceptable variety, it will strike the anvil and rebound therefrom toward and over the segregating member 32 and into the acceptance passage 25.

The advantage of the funnel or scoop-shaped entrance formation H on the gate, resides in the fact that it prevents jamming by deposit of a plurality of coins in quick succession whether the coins are legitimate or spurious, it being possible in either case to cause coin elements to col lect at the entrance region, one such method being to deposit a magnetically attractable coin element first, with the knowledge that it will be struction of the enlarged entrance scoop are de scribed and claimed in our copending application, Serial No. 250,679, filed January 13, 1939.

The present arrangement of the enlarged entrance structure includes an improvement over the disclosure of the aforementioned application in the form of the drop-out opening l9 and, in

addition, the coacting feeler 40, for it is impossible to cause certain undersized coin elements to collect in the enlarged entrance l8 by depositing the same in quick succession, since such elements will pass through the opening l9 as rapidly as they are deposited, the deflector portion 46 assuring positive action in this respect. When the gate is opened, any collection of coins in the enlarged entrance region I 8 will tend to move more 7 or less in unison into the chute section 22 as soon as the gate opens far enough to withdraw the ledge 28 from supporting position.

The sweep begins its dislodging movement at the time the gate starts to open, and the coin arrested by the magnet 50, as well as any additional coins lined up behind the first coin, all move downwardly, the arrested coin being moved as a result of the downward movement of the sweep, and the succeeding coins being freed to move as a result of the opening of the gate.

This is an advantage over an arrangement wherein the sweep and gate operate successively,

to dislodge said first coin. If such fraudulent manipulationof the gate does not succeed in working one of the following coins past the first coin, it may, nevertheless, succeed in jamming the chute by causing a second magneticallyattractable coin to be worked in position alongside the first so that the sweep will subsequently engage only one of the two coins attracted by the magnet and the sweep may become jammed by the remaining attracted coin when the gate is subsequently closed.

Another feature of the invention in connection with the sweep resides in the provision of an ofiset blocking arm 15 (Fig. at the free end of th sweep. Assuming that two coins A and B, both magnetically attractable, are arrested in the positions shown in Fig. 5, the second coin B will be prevented from movement by attraction toward the magnet 50 when the coin A is swept downwardly by the sweep 60 as a result of the positioning of the arm in blocking position in the path of the coin B. Otherwise, if it were not for the provision of the blocking means 15, the second coin B could be attracted in behind the upper edge of the sweep arm 60 when the latter had been fully lowered so as to block movement of the sweep back to normal position, thus jamming the chute.

The objects and advantages of the invention may be realized in other forms of construction, and the arrangement described specifically for purposes of illustration is not to be considered a limitation, it being the intention that the invention should be broadly interpreted in accordance with the appended claims.
