Serial No. 100,859.

This invention relates to coin counting machines. n Coin counting machines have been heretofore made, but they did not give perfect satl" isfaction for a number of reasons, among which may be mentioned the fact that sticking frequently occurred so that themachine was not certain in its action, and also the absolute accuracy required of these machines was not always attained. For example, when electrical contact Was made by the passing coins, it was found that these machinesfrequently skipped a count, and consequently, could not be relied upon. r Objects of this invention are to provide acoin counting machine which is absolutely accurate in its operation, which may be associated with a coin separator to receive the coins directly therefrom, which does not employ any electrical contacts whatsoevenbut instead, utilizes mechanical operations for positively actuating the counters.

Further objects are to provide a novel form of coin counting machine in which energy is mechanically imparted to the coin so that it can exert suiiicient force to insure the; operation of the coin counter, and in which all possibility of sticking or improper actuation of the counter is avoided.

Further objects are to provide a simple type of coin countingvmachine which may be operated Without any thought on the part of the operator, and which is free from fragilek or'delicate parts.

An embodiment of the invention isshown in the accompanying drawings, in which:

Figure 1 is a sectional view through a portion of the counting machine.

Figure 2 is a front view of the apparatus with parts broken away to more clearly show the construction.

Figure 3 is a sectional view approximately on the line-33 of Figures l and 2.

Figure 4 is a fragmentary detail of onevof the counter arms and the adjacent portion of the actuator.

Referring to the drawings, it will be seen thatl the coin counting machine associated directly `with a coin sorting machine, such as o 5 that discloseain my patent No. 1,526,762 for cal chutes 4 and are discharged into the appropriate hoppers or receiving compartments 5. Preferably, a spring finger 6 is positioned in each of the coin chutes 3 to prevent the coins from jumping upwardly as they pass the mechanism for forcing them past the counters, such mechanism to be hereinafter described in greater detail.

Further, it is preferable to provide spring fingers 7 projecting slightly across the lower if ends of the delivery chutes 4 so as to turn the coins and cause them to fall flatly into the ho pers. r

t is tobe noted, particularly from Figures 1 and 3, that the plate 2 is slotted toreceive the ribs 8 of an actuating or driving roller 9. This roller is mounted upon a transverse shaft 10 as shown in Figures 1 and 2, kand is preferably provided with a pulley 11 belted to an electric motor or other suitable driving means such as indicated at 12. The ribs 8 are preferably formed of rubber or other yielding material and project slightly through the plate 2 beneath each of the channels 3. These ribs are adapted to engage the coins as they pass through the chutes 3, one of the coins being indicated in Figure 4 by the reference character 13. Immediately above the plate 2 and adjacent the apertures therethrough are pivoted a plurality of levers or actuators which are provided with a coin contacting arm 1li-See Figure 1 and with an upper arm 15. The upper arm, preferably, carries a spring 16 at its outer end adapted to contact with the roller 17 of the counter arm 18. This counter arm in each instance is clamped upony the counter shaft 19. Conventional types of counters, such as indicated at 20,.may be employed, and as previously described, their operating arms are actuated by the lever 15 through the medium of the spring 16, such spring affording the requisite yield to prevent binding or other damage to the counter arm. These levers or actuators are each mounted upon a transverse shaft 21, and one of each of the levers or actuators is associated with each ot the channels 3. A transverse rod Q2 is positioned beneath the arms 15 ot these actuators and a-tlords a rest therefor.

Each ot the counters 20 is provided with a clearing lever or arm Q8. Each of thes arms carries a pin Q4. Means are provided for simultaneously clearing the counters, and such means may comprise a transverse slide Q5 provided with a plurality of notches 26 adapted for the reception of the pins Qaias shown most clearlU in Fil/gares 2 and 3. This slide 25 is guided in the side trames 27 ot the coin counting machine. It is preferably provic ed with rack teeth 28 which lengage the segmental gear 29. rllhis segmental gear is provided with an upwardly projecting lever 30 equipped with a handle 31. Thus, when the handle 31 is manipulated, the counters are simultaneously cleared, and the machine is in condition tor a further cycle of operations.

The operation of the machine is as follows:

Assuming that the coin sorting machine is in active operation, it will be seen that the coins are ted downwardly to their appropriate passages or channels 3. They pass downwardly along these channels to a position beneath their appropriate levers 14 as shown in Figure 1, At this point, the coin has additional energy supplied thereto by means of the roller or drum 9 whose projecting ribs 8 trictionally engage the lower ledge of the coins and move them beneath the levers 11i, thus raising such levers. The arm or lever 15 is accordingly raised as it is integral with the lever 14, and through the medium ot the spring 16, positively actuates the counter arm 18.

It is to be noted particularly that the momentum ot the downwardly passing coin is not relied upon to operate the actuator, and consequently, the counters, but additional energy is imparted to the coins by means of the transverse roller so that the coins are positively passed beneath the levers 14 in a mechanical and certain manner.

Certain of the chutes or passageways 3 may be provided with springs such as indicated at 8 in Figure 2 to insure the vertical positioning ot the coin. F or example, in the dime chute or channel, a spring has been shown as positioned upon the side of the channel and projecting slightly there into. This spring keeps the coin from tilting, although the coin may be extremely thin.

It is to be noted also that the guards 6 prevent the coins trom jumping upwardly as they pass the roller, and consequently, guide' the coins into the chutes 4;.

It will thus be seen that a positive and reliable count of the coins is assured by this machine.

As a. matter of actual fact, these machines have been tried and have been found to give absolute accuracy in the counting ot the coins.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim: Y
