SMITH, F GIRARD, PENNSYLVANIA, ASSGNOR T O THE GIRARD MODEL 'WORKS INC., OF GIRARD, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA nnersrnnrne BANK application :filed March 5, 1929. Serial No. 344,291.

This invention relates to registering mechanisms and more particularly to coin registering savings banks.

The primary object of the present invention is to improve coin registering savings banks, such as have been disclosed in the coending application of Stanley L. Connell,

^ erial No. 265,889, led March 30, i928.

ln registering mechanisms the construci@ tion, is sometimes sought to be simplified by forming a toothed Wheel, intended to rotate with a registering Wheel, integrally therewith by the simple expedient oic striking the teeth out from the side oit-the registering i5 Wheel. Such an arrangement results in teeth which are Weak, and which do not present a smooth rounded tooth face. @ne object of my invention is to improve such a structure by providing teeth which are 2o stronger, more rigid, larger, and which present a smoother tooth ace, Without mean- While increasing the diiculty of manufacturing lthe Wheel.

.Further objects of the present invention a5 are to apply such-a Wheel as the ratchet Wheel of a registering mechanism such as is described -in the copending application already referred to, and by its use, together with an improved pavvl mechanism, to make the indications of the registering Wheels more accurately centered or indexed.

A A. ratchet Wheel such as has already been described is open-faced, that is, because the teeth are struck out from one side of a disk the remote ends of the teeth are open-ended. There consequently is a tendency tor the paWl which cooperates with such a ratchet Wheel to slide oii' the ends of the teeth, a tendency the counteraction of which is still another object of my invention. l

The registering bank already mentioned is equipped with a bell and bell clapper system which is rung upon depression of t e operating arm or key of the bank. This arrangement is faulty in that it ermits the bell to be rung even though no com has been deposited in the bank, and accordingly, a urther object of my invention is the provision of a bell ringing mechanism which is operative only when a coin is actually being registered. Another object of the present invention is to cause the bell to ring a number of times which is commensurate With the denomination of the coin being registered by the bank. A still further object orp the present invention is to provide a bell ringing system Which is so advantageously combined with other mechanism Which is anyway needed as part of the registering mechanism that no appreciable complication is introduced by the addition thereto of the bell ringing mechanism. v

ln order to encourage savings the depositor should, ii possible,be given a goal toward which his savings are directed. Accordf ingly, another object of my invention is to provide the door of a coin registering savings bank with a lock which is automatically opened only after a predetermined total has been deposited in the bank. At the same time, inasmuch as it is not desirable to have to break open the bank if, for some reason, the deposited savings must be Withdrawn before they attain the. predetermined total, l provide a manually operable key for releasing the lock which ordinarily is automatically released by the registering mechanism. This key may be kept in the custody oi:D someone other than, and in supervisory relation to, the depositor.

'lo the accomplishment of the foregoing and such other objects as Will hereinafter appear, my invention consists in the elements and their relation one to the other, as hereinafter are more particularly described and sought to be deiined in the claims; reference being had to the accompanying drawings which show a preferred embodiment of my invention, and in which:

4, showing the door and lock mechamsm.

vReferring to the drawings, the coin registering savings bankl comprises generally a casing 2, coin registering mechanism 4, andA a door and lock mechanism 6.

, The casing 2 is substantially similar to that described in the copending application already mentioned, and may be briey described as generally simulating a cash register. Itis composed of sheet metal sides which are itted together with tongue and slot joints,.and is provided with coin slots 10, of proper dimension, sight windows for the registering wheels, and other features, which will be described as the need arises.

A coin of appropriate denomination is dropped into one of the slots l() in the casing, and thence falls into the corresponding one of the chutes 12 where, by its presence, during downward depression of the operating arm orkey 22, it causes the registering mechanism to add to the total registration indexed by the wheels an amount commensurate with the denomination of the coin. Upon completionof the downward oscillation of the key the coin drops out of the chute into the bottom of the casing, where it remains and is saved with the other dey. posited coins until the door 6 is opened, when appropriate denomination, dropped into the chute, comes to rest against the rollers and a lat cam member 16. The cam member 16 i is pivoted on trunnions 17 in an oscillatable yoke 18, which is oscillated about the main shaftr20 of the registering mechanism by means of an operating key or arm 22, as is b'st shown in Figs. 2, 3 and 5. The cam 16 carries an operating pawl 24, integrally formed therewith, which normally is kept out of engagement' with the ratchet Iteeth 26, as is shown in Fig. 2, by reason of the tension of aspring 28. However, when the operating arm 22. is pressed downwardly, rotating the yoke 18 with it, the cam 16 is moved radially toward thev shaft 20 about the-trunnions 17 as it rides along the edge of the coin supported against the rollers 14 in the chute 12, and this inward'movement brings the operating pawl 24 into engageface 16 against the edge of the coin has' moved the operating awl 24 radially inwards between two ad ratchet wheel, so that the continued oscillation of the operating arm 22 causes the combined ratchet wheel and `registering wheel 30 to rotate. The amount of rotation 'is made commensurate with the denomination of the particular coin then being registered by varying the eiiective operating length of the cam 16, as may best be observed in Figs. 4 and 5, where it will be seen that the operating length of the cam, at the dime chute, is twice as long as it is at the nickel chute, while at the quarter chute it is five times as long as it is at the nickel chute. rlhe number of the ratchet teeth 26 is made equal to or is related by a small whole number to the number of indications on the registering wheel, and the ,effective operating lengths of the dili'erent portions of the cam 16 are properly related to the spacing of the ratchet teeth to obtain the desired movement. The registering wheel is kept at prper index by a holding pawl 32.

or economy in manu acture the registering wheel 30 is made up of two sheet metal halves which fit together to form a drumlike cylinder, and the teeth 26 are stamped out from the disk or side of one of these halves. With such a construction, which, it may be remarked, is applicable to registering mechanisms in general, it is ditlicult to obtain teeth of suiiicient strength and rigidity, and according to one important feature of my invention these teeth are so formed that, while extending normally of the disk, they are arcuate in coni uratioii or cross section, as is best indicate by the teeth 26 in Fig. 6 of the drawin re resenting al section thru one-half of t e w eel 30. This feature strengthens the teeth, augments their rigidity, and also results in a smoothertooth face or working face a ainst which other mechanism, for examp e an operating or a holding pawl, may bear. Furthermore, in accordance with my invention these teeth are stam edout as near to the periphery of the w eel as is conveniently possible, thereby permitting them to be made as large as possible, which further serves to strengthen them. In the particular mechanism here disclosed the latter feature permits the operating and holding jacent teeth of thepawls to be so shortened that there is no dfliculty in making them suiiiciently rigid for accurate response. This accuracy of indication or index of the registering wheels is further promoted by increasing the size of the pawls, giving them a broad and rather blunt triangular shape, so that they completely fill u the space between the teeth 26 of the wlieel 30, and thereby make the resulting movements and indications of the wheel quite exact. Y

The registering wheel 30 is held in position, after the operating pawl 24 has been retracted from the ratchet teeth 26 by the spring 28 when the cam 16 has passed and released the coin last registered, by a holding pawl 32, best shown in Figs. 2, 3, and 5. This pawl is pivoted on a spindle 34, which, like the main shaft 2Q, is journalled in the sides of the case 2 of the savings bank. In accordance with one feature of my invention the holding pawl 32 has a wide short triangular tooth 36, the leading side of which has less slope than the following side in order to permit the ratchet teeth to move past the pawl without too much diiliculty, and for another` reason described A later. The pawl is made of sheet metal, and

in order to take the wear, the leading side of the tooth 36 is given a large bearing surface by bending a flange of the sheet metal over, as at 38, a feature which is perhaps best shown in Fig.- 5 of the drawings. By reference to Fig. 2 it will be noticed that the tooth 36 is suiiciently wide to completely ill up the space between adjacent teeth of the ratchet wheel, and so to definitely fix the index of the wheel.

The mode of interconnection of the cent registering wheel 30 with the next or dollar registering wheel in the registering train need not be described, for it is described in the copending application already referred to, and may be of any conventional type regularly employed in this type of mechl amsm.

The ratchet teeth, being formed by stamping them out of one side of the registering wheel 30, are open at their other extremities, so that there is a tendency for the holding pawl to move sideways and ofi' the ends of the teeth, a tendency which is not completely overcome even though a disk 40 is provided for the purpose of closing the ends of these teeth. In accordance with my invention the pawl 32 is free to move axially along the spindle 34, and the tension spring, which is stretched between the cam 16 and the holding pawl 32 in order to obtain thedesired resilient action of both of these members, is positioned at an inclination, evident irom an inspection of Fig. 4, which is in the proper direction to tend to pull the pawl toward the wheel 30, and so to hold it 'in engagement with the ratchet teeth 26, The reaction of this tension is taken by the yoke 18 against a thrust bearing 42 on the main shaft 20 of the registering mechanism. In order to prevent the holding pawl from moving past the edge of the wheel 30 the pawl is provided with a'bearing portion 44, which, even when the pawl is depressed out of engagement with the ratchet teeth, still bears against the side of the ratchet wheel 30, and so prevents the pawl from moving too far in that direction. f

lt is desirable to obtain an audible indication of the registration of coins in the bank, and this indication should preferably not be obtained simply as a result of depressing the operating arm 22, for then it could be sounded at will even though no coin is deposited in the bank. With these objects in view I provide a bell and bell clapper system which is actuated by the movement of the holding pawl which anyway results when a coin is registered. More specifically, there is a bell 50, supported on the back side of the bank, and a bell clapper or striker 52 which is'loosely held on an extensionv 54 of the holding pawl 32. It has already been mentioned that the following side of the holding pawl tooth 36 is relatively steep, so that, as a ratchet tooth 26 rides past the leading side 38 ot the holding pawl the bell clapper 52 is raised smartly under the tension of the spring 28, and this motion is continued by inertia, owing to the loose fastening between the striker 52 and the holding pawl extension 54, until the striker hits the bell. With this arrangementJ the bell is not rung except when a coin is actually deposited and registered by the bank. Furthermore, the bell is rung, say,

once if a nickel is deposited, twice if a dime is deposited, and live times if a quarter is deposited, that is, the bell may be rung a number of times which is commensurate with the denomination of the coin then being deposited in the bank.

It has already been mentioned that the bank is provided with a locked door or closure'6` for removing the coins deposited therein. My invention includes means actuated by the registering mechanism for releasing the lock upon depositing a predetermined total this, reference is made to an interior View of the door, shown in detail in Fig. 7, where it will be observed that the door, when opened, is able to swing outwardly about the contracted portion 60, but normally is locked in closed position by a reciprocable bolt 62 which slides between the inner surface oi' the door and the outer surface of an inner plate 64, attached to the door by tongue and slot joints 66. The bolt 62 carries a lug 68 which extends through a slot 70 in the inner plate 64. A spring 72 is arranged to urge the lug 68 and the bolt 62 Lil in the bank. To describe' into the locking position. The end of the bolt presents a flanged surface against which a tooth 74, struck out from the side ot the last, in this case, the dollar wheel (see Fig. 5) presses when the wheel indicates a pre determined total. This slides the bolt open and unlocks the'door, permitting the deposited coins to be removed from the bank.

ln order that the bankmay be opened before the predetermined total has been deposited I also provide a. manually operable key for releasing the lock at'will. A; key hole 8O is cut through the side ot the bank, and a key is provided which, in the case shown, is a simple form of latch key, the tang of which rides against the flanged end of the bolt 62 and slides it lbackward to open the door. By placing the key in the custody of someone other than the depositor, the latter is encouraged to save, with a desired total always in view, just as though there were no key, but should it become necessary to extract the savings prematurely, this may be done without wrecking the bank. Also, as a toy, the play value oi the bank is very greatly au mented by the provision of both the manna and automatic locking features.

lt will be apparent that while l have shown and described my invention in the preferred `form, many changes and modifications may be made in the structure disclosed without departing from the spirit of the invention, defined in the following claims.
