TRICOIN REGI STER BANK Filed April 11, 1935 [fill INVENTOR. frco Ewen ATTORNEY.

Patented Apr. 14, 1936 UNITED STATES PATENT OFFICE 2 Claims.

One object of this invention is the provision of a registering bank so constructed that it will receive and selectively register nickels, dimes, and quarters, the construction and operation of the bank being so developed and attained that the method of attaining the said object is simple and accurate.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the accompanying drawing.

Referring briefly to the drawing, Fig. 1 is a perspective View of the bank; Fig. 2 is a fragmentary plan view with a portion of the roof removed; Fig. 3 is a cross-section taken on the line 3 3 of Fig. 2; Fig. 4 is a cross-section taken on the line 4-4 of Fig. 3; Fig. 5 is a cross-section taken on the line 5-5 of Fig. 4; Fig. 6 is a view similar to Fig. 4 illustrating the various elements in position after a quarter has been deposited and registered; Fig. 7 is a cross-section taken on the line '|-'l of Fig. 3; Fig. 8 is a. plan view of one of the register dials; Fig. 9 is a view similar to a portion of Fig. 6 showing the position of the pawl lever after a nickel has been registered; and Fig. 10 is a view similar to Fig. 9 after a dime has been registered.

Referring in detail to the drawing, the numeral It! represents the housing of the bank having an opening I l on one side which is closed by a slide door l2 provided with a handle l3. At the top three slots l4, l5, and 16 are provided to expose the dial numbers which show the amount of money deposited. The front wall of the housing is slotted at H and I8, the former to permit sidewise movement of a tongue l9 rigid on an arm 20, and the latter is the coin slot provided with an arched lip 2 I.

Rotatably mounted on one side of the ceiling is a disk 22 provided at one point of its periphery with a pair of teeth 23. A gear 24 having teeth 25 is rigid with the disk 22. A spring band 26 is attached on its edge to the ceiling and provided at one end with a nose or pawl 21 normally urged against the teeth 25, and at the other end with a. similar nose 21a normally urged against the tooth 29 of a disc 28. Adjacent the disk 22 the disk 28 having teeth 29 is rotatably mounted in the ceiling, the teeth 23 of the disk 22 engaging the teeth 29 once during every revolution of the disc 22. The disk 22 is provided on its upper face with the dial number shown in Fig. 8, and the disk 28 is provided with the dial numbers shown fragmentarily in Fig. 2.

A slide arm or member 30 is slidably mounted againstthe front wall of the housing, being provided with an upper extension 3| and a lower extention 32. The latter is bent to provide a stall 33 which normally lies with its entrance against the coin slot 18. A cut-out shoulder 34 is provided at the front part of the stall 33. A coiled spring 35 normally urges the member 30 to the right (Figure 2), being attached at one end to the member 38 and at the other to an upright wall 35. A rocker arm 31 is pivotally at- 10 tached at 38 to the member 30, and normally its pivoted end lies adjacent the wall 36. Near the other end of the arm 31 a tongue 39 extends at right angles from the member 3'! and normally rests on the shoulder 34 of the stall 33. A relal5 tively long and wide pawl 49 extends from the arm 3'! at right angles to this arm and the tongue 33, and above the pawl 43 and spaced therefrom by a slot 4 I, a second relatively narrow and short pawl 42 extends in the same manner from the arm 20 3?. At a point nearer the pivot 38 a third pawl 43 extends in the same manner from the arm 31, the pawl 43 extending outward from the arm 31 substantially the same distance as the pawl 40. The pawl 42 is of such length that the path of 25 its end in being moved in the plane of gear 24 to intersect the periphery of the gear 24, intersects the same to such adepth that the pawl 42 turns the gear 24 through a distance of two teeth, in thus passing the gear 24. The pawl 49 30 is of sufficient length (greater than that of the pawl 42) that the same sliding movement of the arm 3! with the pawl in the plane of the gear 24 will cause the gear 24 to rotate through four teeth. The pawl 43 is so positioned intermediate 35 the arm 3'! that it can turn the gear 24 through only one tooth whenever it moves in the plane of and strikes this gear. Although it would turn the gear through additional teeth if it could continue its travel, it is prevented from doing so by the extension 32 striking the side wall of the housing, the extension 32 serving as a limit stop from the slide. A spring 44 normally urges the arm 31 down on the left (Figure 4). A wall 45 having a slot 46 therein divides the deposit com- 45 partment 47 from the remainder of the housing interior.

The operation of the device is as follows: When a-dime is inserted into the slot [8 it enters the stall 33 and in doing so raises the tongue 39 50 and hence the left-hand end of the arm 31. The latter will thus be raised just a sufiicient distance to cause the pawl 42 to rise into the path of the teeth 25 (Figure 10). Then the arm 30 is slid to the right (Fig. l) to the left (Fig. 6, Fig.

10), to its extreme position where it is stopped by the extension 32 striking the side wall of the housing. In doing so, the pawl 42 will rotate the gear 24 a peripheral distance of two teeth, causing the disk 22 to turn the same angular distance and change the number in the slots l5l5 by adding thereto, as is apparent in Fig. 8. When the slide 30 is in its said extreme position, the stall 33 stands directly over the slot 45, and the coin drops into the compartment 41. If, instead of a dime, a nickel is inserted in the slot l8 and the same operation repeated, the arm 31 is raised upon insertion of the nickel to a higher position (Fig. 9). In this position, with a nickel in the stall 33, the pawl 42 rises above the level of the teeth 25, so that upon movement of the slide 30 the pawl 42 does not strike the teeth 25. Instead, the slot 4| (Fig. 9) is raised into the level of the teeth 25, and as the slide 30 and with it the arm 31, is slid to the left the pawl 43 turns the gear 24 a distance of one tooth, (since the intermediate position of the pawl 43 lengthwise of the arm 3! permits the pawl 43 to turn the gear 24 through only one tooth before it is stopped by the extension 32 striking the housing wall) thus adding 05 to the total in the slots l5|6. When a quarter is inserted into the slot 18 and the operation repeated, the arm 3! is raised still higher, into the position shown in Fig.

6. In this position the pawls 40 and 42 are also inclined further to the right (Fig. 6), so that the engagement of the pawl 40, which is now raised into the path of teeth 25, turns the latter a distance of four teeth, and in addition the pawl 43, at the end of the sliding movement, turns the teeth 25 a distance of another tooth, so that "25 is added to the total in the slots l5i6. When the gear 24 has made a complete revolution, a l is added in. the slot l4, since the 24 will have rotated the gear 28 through two teeth by engagement once every revolution of the teeth 23 with the gear 28; thus registering the dollar total.

As the mechanism for locking the door 12 upon insertion of the first coin in the bank, and for opening the same upon the accumulation of a given total sum, forms no part of this invention, the detailed description of the same has been omitted.

Obviously, modifications in form and structure may be made without departing from the spirit and scope of the invention.

I claim:

1. In a register bank adapted to receive coins of various denominations and having a gear mounted therein and a registering dial operated by said gear upon rotation of said gear, said bank having a coin slot for the insertion of coins into the bank, a slide mounted behind said slot and having a stall adapted to receive the inserted coins, a rocker arm pivotally mounted at one end of said slide and having its free end normally resting against one end of said stall, a resilient means for urging said free end against said stall, a wall rigid with the bank lying adjacent the other end of the stall, the inserted coin passing into said slot and pushing the free end of said arm away from said stall, a larger coin pushing said free end a greater distance away from said stall than a smaller coin, pawls on said free end adapted to be selectively pushed into the plane of said gear according to the size of the coin, said pawls lying at substantially right angles to said arm and being of varying lengths, the longer of said pawls when thus pushed into the plane of said gear and upon sliding of said slide and arm toward said gear causing a relatively deep intersection of the path of said longer pawl with the periphery of said gear so as to rotate said gear through a relatively greater arc, the shorter of said pawls similarly causing a relatively shallow intersection with the periphery of said gear to rotate said gear through a relatively shorter are upon sliding of said slide and arm toward said gear.

2. In a bank adapted to receive coins of varying denominations and having a gear mounted therein and a registering dial operated by said gear upon rotation of said gear, said bank having a coin slot for the insertion of coins into the bank and a rigid wall adjacent one end of said slot, a slide mounted behind said slot and having a rocker arm pivoted at one end thereon, the free end of said arm having a pair of pawls normally lying adjacent the other end of said slot and lying in a plane at right angles to the arm and having a slot therebetween, one of said pawls being of greater length than the other, a third pawl on said arm in a plane parallel with the first-named plane and intermediate the length of said arm, said free end of said arm normally traveling in a path adjacent the plane of said gear upon sliding said slide, means for normally retaining said free end of said arm in said position adjacent said slot, the insertion of a coin of small diameter through said coin slot causing said coin to push said free end of said arm a short distance beyond the end of said coin slot and the shorter of said pawls into the plane of said gear so that subsequent sliding of said slide and arm will cau e said shorter pawl to rotate said gear through an arc, the insertion of a coin of next larger diameter through said coin slot causing the latter coin to push said free end of said arm a greater distance beyond the end of said coin slot and the slot between said pawls and also said third pawl into the plane of said gear so that subsequent sliding of said slide and arm will cause said third pawl to rotate said gear through an arc, the second named are being shorter than the firstnamed arc, a limit stop to the slide movement of said slide, the intermediate position of said third pawl on said arm causing said third pawl to reach the end of its slide stroke after rotation of said gear through a shorter arc than said first-named arc, the insertion of a coin of still larger diameter through said coin slot causing the latter coin to push said free end of said arm a still greater distance from said coin slot so that upon subsequent sliding of said slide and arm the longer of said pawls will cause said longer pawl to rotate said gear through an are greater than said first-named arc and at the same time said third pawl will rotate said gear through an additional arc of the same length as said secondnamed arc.
