7 Claims.

My invention relates to coin handling machinery, and especially to coin counters of the centrifugal disc type of which it provides an improved form. It can be explained best by reference to the accompanying drawings.

It is not entirely limited to this type of machine however, in all its respects, as will be apparent. Also it is applicable to coin-like tokens and other articles coin like in shape, as well as to coins, and all these are included in the term coin as that term is used hereinafter.

The accompanying drawings illustrate a centrifugal coin counter with the best form of my invention of which I am now aware applied thereto. Fig. l is a vertical section of the counter, substantially on its center line. Fig. 2 is an elevation of the discharge end of the machine. Fig. 3 is a plan view.

The rotary table or centrifugal disc I is supported substantially horizontally by the machine frame 2; conveniently it is rotated by a vertical center shaft 3, for example, through suitable gearing, and is carried by a thrust bearing 4 surrounding the shaft; the outer edge 5 of the disc or table may, say, rest lightly on the machine frame 2 for steadying purposes. A vertical retaining wall 6 and extensions of it later mentioned prevent the escape of coins by upward and outward movement. At a lower level an outer substantially vertical wall 1, outside of but close to the edge of the table or disc, encircles the table or disc completely except at a point 8 (Fig. 3) where a passage 9 is provided for the escape of the coins seriatim from the table to the counting mechanism. A plate or guide It, placed inwardly of the wall 1, has a forward edge to help direct coins from the disc into the passage 9 and a supplementing retaining wall l6, joining retaining wall 6, is placed above the inner edge of plate l0, all as will be apparent from Fig. 3. From the passageway 9 the coins slide on the frame for a short distance at H and thence into the receptacle provided to receive them, or a chute l2 in the present in- 45 stance. At H the coins pass seriatim underneath a driven wheel l3 and across the edge of a notched wheel [4 which forms a part of the counting mechanism l5; under the driving force of the wheel l3, or the force with which the coins are thrown from the rotary table supplemented by the driving force of this wheel, each coin is forced to turn the notched wheel l4 one notch and thereby actuate the counting mechanism l5. Counting mechanism suitable for the purpose and likewise the action of a driving wheel such as that at l3 and the action of the coins on a notched wheel like M are well known so that no further description of these parts is necessary. Also, in advance of the passageway 9, an overlying wall 29 extends inwardly from the outer wall I for some distance, above and substantially parallel to the face of the disc or table, and in operation this overlying wall is spaced from the table a distance approximately equal to the thickness of the coin to be handled. In cooperation with the disc face and the outer wall I the overlying wall 20 provides a runway as it were leading to the exit passage 9 and thence from the table. Means are provided for adjusting the wall 29 closer to or farther from the face of the rotary table i, so the coins of one size can be handled at one time and coins of another size at another time. Also a directing plate 2! is provided to cause each coin to enter a notch in the notched wheel l4, and this plate is slidingly mounted so that it can be moved toward and from the notched wheel M, by means of the hand lever 22, to provide for the handling of coins of different sizes. Machines of the type thus described are well known. In operation, in brief, coins are cast on to the rotary table or disc I, and by the rotary action of this table the coins which lie flat on the table are worked toward the outer edge of the table against the wall 7 and into the runway underneath the wall 29, so that ultimately they are cast through the exit slot 9, whence they are counted and cast down the chute I2 by the counting mechanism [4, l5 and the driven wheel [3.

As these machines have been built heretofore however, there is considerable tendency for the coins to assume vertical positions against the retaining wall which prevents their escape from above the disc, and in this position they not only cannot enter the runway underneath the overlying wall 29 but prevent other coins from entering the runway. My invention tends to materially prevent this action and, generally speaking, to provide an improved action. To this end, I carry the overlying wall 2|] only part way around the vertical axis of the table, for example through an arc of about one hundred degrees as appears in Fig. 3; a further supplementing retaining wall 24, joining retaining wall 6 and also joining retaining wall It, is placed above the inner edge of this overlying wall. Immediately adjacent the periphery of the rotary table I I extend the outer wall I upwardly at substantially right angles to the face of the table for a distance substantially equal to the thickness of a coin. Above the coin thickness the retaining wall 6 is then extended outwardly for a little distance, at an angle to the horizontal as indicated at 23 in Fig. 1, forming there what may be termed an inclined wall; externally of this inclined surface 23, the retaining wall 6 may rise vertically as is also shown in Fig. 1. As a result of the surface inclination at 23, no coin finds a vertical surface against which it may lean indefinitely as it rolls around with the rotation of the table resting on its edge on the rotary table, but any coin rising on its edge as it bears against the vertical surface I, must topple over,

either inwardly or outwardly, and if it topples outwardly the inclination at 23 serves to cause the coin to work itself face downwardly on to the top of the rotary table, i. e. into the position the coin must occupy in order to enter the runway underneath the overlying wall 20. This wall arrangement, including the incline at 23, extends around, preferably, so much of the disc as is not covered by an overlying wall 26, or a dividing plate l9. Also as may be understood from the foregoing, the under surface of the overlying wall 2|) is placed at about the same height as the juncture between the inclined surface 23 and the vertical surface I and the supplementing retaining wall 24 extends along substantially the end of the incline 23, so that the overlying wall 20 and the retaining wall tend to sweep fiat down onto the table any coin that may come to the overlying wall resting on the incline. By making the height of the vertical portion 7 of the encircling wall at least equal to the thickness of the thickest coin to be handled (it may be greater than this), and by providing for the raising and lowering of this outer wall I, the incline 23 and the overlying wall 20, the machine is adapted to handle coins of different thicknesses at different times, but all in the same manner. Thus for dimes, for example, these parts would be lowered to such a point that the vertical distance between the top of the rotary table and the juncture between the vertical surface I and the incline 23 is just about equal to the thickness of a dime; if quarters are to be handled, these parts will be raised to such higher position that this vertical distance is about equal to the thickness of a quarter. To this end and also for convenience of construction the retairing walls, including the incline 23, the overlying wall 20 and the outer wall 1| are formed preferably into a single unit and preferably as an integral unit as illustrated.

It will be observed of course that the substantial parallelism between the face of the rotary table and the under surface of the overlying wall 20 should be maintained as this wall is raised and lowered; also it is desirable that the substantial parallelism be maintained between the surface of the rotary table and the line forming the juncture between the vertical surface I and the incline 23. Any mechanism capable of raising and lowering these parts (either as portions of a single unit or otherwise) meanwhile maintaining this parallelism, and which otherwise is suitable, can be employed. I have found however that a lever system operable as a whole from one point and engaging the unit member at a plurality of points is preferable; engagement at three substantially equally spaced points is suincient, Preferably too this unit member is carried on springs 30, say one at each of these three points and the lever system acts to depress the unit member against the springs; this arrangement positively locks the overlying wall 20 against upward movement, thus positively preventing the entrance of a bent coin into the runway. Preferably also the lever system is actuated by a thread 3| and nut 32 mechanism, the thread being, say, drivable by the machine operator through a suitable hand hold 33 which may be indexed as at 34 to indicate its proper settings for various coins. The preferred form of lever mechanism is illustrated. In brief, the unit rests on three evenly spaced posts 36 which are slidable in machine frame 2 and supported each by one of the springs 35 (Fig. l) a threaded bolt 31 serves to tie the member to each of these posts 36 and at the same time permits its ready release from the posts. At their lower ends, each post is recessed to form a yoke 38 into which a vertical bolt 39 extends for adjusting purposes; one end 40 of an arm or lever extends into engagement with the bolt 39 at each of these posts. Each of these arms or levers is pivoted to a bracket 6| mounted on the machine frame, by means of rock shafts 42 and 43 to which, in the present instance, these levers are keyed. To the rock shaft 42 which is more remote from the thread-and-nut mechanism 3|32, is keyed an arm 44, the opposite end of which is suitably connected to the nut 32 so that the raising and lowering of the nut 32 by its threaded member 3| serves to swing the arm 44 and thereby swing the shaft 42; a link 45 serves to connect the two shafts 42 and 43, so that one swings the other to an equal degree. By connecting the thread-and-nut mechanism to the more remote shaft 42, a finer and more accurate adjustment is obtainable than where the connection is made to the nearer shaft 43. From the foregoing it will be observed that by raising the nut 32 by turning the hand hold 33, all the lever arms 4|) are depressed, and thereby the three posts 36 are depressed equal distances and the unit member including the outer wall 1 and overlying wall 20 is carried. down in parallelism; turning of the thread 3| in the opposite direction permits them to rise.

Usually the periphery of the driving wheel I3 is faced with rubber or other material suitable for gripping the coins to slide them along, and heretofore difficulty has been experienced in the abrading and flattening out of the face of the wheel. This is due, I have found, to the fact that the face of the wheel frequently comes into engagement with the cooperating surface against which it presses the coins (surface II in the present instance); perhaps too it is due in part to the fact that the wheel is called on to handle thick coins as well as thin ones. In any event, I find that this difficulty can be avoided by so mounting the wheel that the wheel is permitted to move rather freely toward and from its cooperating surface, and at the same time by limiting the movement of the wheel toward this cooperating surface to such an extent that the wheel can never engage this surface. To these ends preferably, I mount the wheel on a shaft provided at its outer end with a driving connection, say a pulley 5|, quite as before. The bearing 52 for this shaft, I hinge however adjacent the pulley 5|, 1. e. at 53, on a horizontal axis transverse to the shaft. The bracket 55 nearer the wheel l3 permits this end of the bearing to rise and fall but at the same time keeps the shaft in the desired line. As a consequence, the wheel |3 can rise as a coin comes underneath it, rising more for a thick coin than for a thin coin, and, by reason of the hinge mounting described, it has this motion without unduly disturbing its driving. A hook 55 engaging a projection 56 from the bearing, and carried say in a small bracket 51 extending from the main bracket 54, serves to prevent the wheel 33 swinging down so low as to strike the cooperating surface II; for accurate placement, the hook 55 may be positioned by a bolt and nut 58, Also if desired a spring can be used to press the wheel 13 into contact with the coins; for example, a sliding plunger 59 engaging with the bearing 52, can be provided in the bracket 5 and surrounded by a spring 60 for the purpose. The upper end of this spring may rest against a threaded bolt 6i, so that its tension is adjustable. It will be observed that this arrangement provides for the wheel l3 bearing against each and every coin with adequate pressure to drive the coin along the surface I l, without at the same time the thicker coins calling on the wheel l3 to exert undue pressure.

It will be understood that my invention is not limited to the details of construction and operation illustrated and described above, except as appears hereinafter in the claims.
