G01N CLOCK BANK.

Application led .August 16, 1922. Serial No. 582,192.

To @ZZ whom t may concern:

Be it known that we, ALPHONSE C. Knr- TERER and GEORGE P. SLANKER, citizens of the United States, residing at Santa Barbara, in the county of Santa Barbara, State of California, have invented a new and useful Coin Clock Bank, of which the following is a specification.

Broadly considered, it is the object of this invention to promote thrift, by constraining a person to deposit a coin, whenever a clock is wound, it being impossible to wind the clock until a coin is deposited.

It is contemplated that the winding shaft of the clock shall be shielded by a guard, to the end that the winding key cannot be placed upon the shaft until the guard is released, and, specifically, the invention aims to provide novel coincontrolled means for releasingthe guard, means being provided for resetting the guard with respect to the winding shaft.

Another object of the invention is to pro vide novel means carried by the winding shaft, whereby `the guard may be reset, said means being so constructed that it will in no wise interfere with the winding of the clock or impede the rotation of the winding shaft, as the clock runs down.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings z-Figure 1 shows in rear elevation, a device constructed in accordance with the invention; Figure 2 is a vertical section, wherein parts appear in elevation; Figure 3 is a section on the line 3 3 of Figure 2, the line 2-2 in Figure 3 indicating the cutting plane on which Figure 2 is taken; Figure 4 is a fragmental horizontal section taken through a portion of the casing, the coin chute, and attendant parts; Figure .5 is a vertical section disclosing the mounting of the arm which carries the dog.

In carrying out the invention, there is supplied a. case or support 1, provided at its lower end with a money receptacle 2` which may be in the form of a drawer, held closed by a loch 1t is obvious that the taste of the public with regard to ornan'ientation, the desire for compactness, and other considerations, will dictate the form of the case., the specific case, money receptacle and lock, shown in the drawings being illustrative merely, and not mandatory. A coin chute 4l is mounted on the rear wall of the case 1 and discharges into the receptacle 2, the chute opening through the top of the case, if desired. A clock casing 5 is held by clamp brackets 6, or otherwise, on the forward wall of the support l. The mechanism within the clock casing 5 may be constructed as desired, but it is preferred that this mechanism be of such a nature that the clock must be wound frequently, since it is proposed that a coin must be deposited each time that the clock is wound, the amount of money saved being increased, by the depositing of each coin. It is therefore suggested that the device be used in connection with a twenty-four hour clock, comprising a winding shaft 7, a setting arbor 8, and a regulator 9, the back of the case 1 having a slot 10, giving access to the regulator 9, the winding` shaft 7 being accessible through an opening 11 in the case 1, the case having an opening 12 whereby a key may be placed upon the setting arbor 8.

Comparing Figures 3 and 5, it will be observed that the winding shaft 7 has a 'fixed disklilre shoulder 14. A compression spring 16 bears at its inner end against' the shoulder 14 and surrounds the squared p0rtion of the shaft 7, the outer end of the spring 16 bearing against the upper end of an angular spring strip 15, slidable on the squared portion of the shaft T and secured at its lower end to the clock casing 5, the strip 15 constituting a key-ejector for the shaft 7, as will be explained hereinafter.

An arm 17 is mounted for vertical swinging movement on the winding shaft 7, to the rear of the shoulder 14. The arm 17, however, is held frictionally on the winding shaft 7, so that when the winding shaft is chute 4.

of the coin chute 4.

rotated, the arm may swing. lith this end in view, a compression spring 19 surrounds the inner portion of the winding shaft 7, one end of the spring abutting against the clock casing 5, and the other end of the spring abutting against a washer 13 on the winding` shaft, the washer engaging the arm 17 and pressing' the arm against the shoulder 14, under the impulse of the spring 19, the arm thus being held frictionally on the shaft 7, for movement with the shaft. Stops 20 and 21 project rearwardly from the clock casing The stops 2O and 21 engage the arm 17 and hold the arm, thereby permitting the winding shaft 7 to rotate in the arm. under conditions which will be set forth when the operation of the device is explained.

The numeral 22 marks a dog, mounted to swing parallel to the arm 17, on a pivot element 23 carried by the arm. A spring 25 is mounted on the pivot element .3 and engages a projection 24 on the dog, to swing the dog with respect to the arm 17, the pro-I jection 24, however, being adapted to cooperate with the arm, to limit the swinging movement of the dog` responsive to the spring 25. The dog 22 is provided with a convened outer edge 26 and with a concaved inner edge 53.

A vertical guide 27 is supported on the reai' wall'of the case 1, and within the guide, a disk-like guard 23 is movable, the guard having an opening 29 adapted to be brought into and out of registration with the opening 12 in the rear wall of the case 1. The guard23 has an upstanding arm 30 carrying a forwardly presented 'linger 31 wherewith the dog 22 is adapted to cooperate. '.vlhe guard 23 includes a bell crank lever 32, fulcruined at 33 on the rear wall of the case 1 for vertical swinging movement, swinging movement of the bell crank lever 'in the direction of the arrow A in Figure 1 being limited by a stop on the rear wall of the case 1. The upstanding arm of the bell'crank lever 32 is supplied with a forwardly projecting detent 43.

The numeral 35 designates an angular latch, including arms 36 and 37, the arm being adapted to cooperate with the detent 43 on the bell crank lever 32, and the arm 37 carrying a lateral projection 39 received in atransverse slot 4() formed in the inner edge The latch 35 is carried by a fulcrum element 38 mounted in the coin A weak spring` 41 is anchored at one end on the coin chute 4 and is engaged about the fulcrum element 38, the spring coacting with the arm 36 of the latch 35.

to holdr the latch in the position delineated in Figure '2 of the drawings.

When the parts are arranged as shown in F igure'). the projection 39,1011 the arm 37 Y et the latch 35 isl located in/the slot 40 of the opening' 29 in the guard does not coincide i with the opening 12 in the vcase 1, it being impossible to apply a key to the arbor- 8 and set the hands of the clock. Further, the guard 23 is interposed between the shaft 7 and the opening 11 in the rear wall of the case 1, and, consequently, 'an operator cannot apply a key vto the shaft 7 and wind the clock. If a coin 50 be deposited in the chute 4, the coin will pass downwardly through the chute into the receptacle 2.

The coin 50, moving downwardly in the coin" chute 4, strikes the projection v39 on the arm 37 of the latch 35 and tilts the latch on its fulcrum 38, the weak spring 41 being overcome, the arm 36 of the latchbeing raised ont of engagement with the detent 43 on the bell crank lever 32, and the bell crank lever being set free. The guard 23 acts as a weight, and causes the bell crank lever 32 to swing on its fnlcrum 33 until l the opening 29 in the guard is brought into coincidence with the opening 12 in the case 1, whereupon a key may be applied to the setting arbor 8. When the guard 28 moves downwardly, the winding shaft 7 is uncovered. and the operator may apply a key to the shaft, to wind the clock, When the guard 23 moves downwardly, to expose the shaft 7 and the arbor 8, the arm 30 and the vfinger 31, which form part of ther guard, are carried downwardly, until the linger 31 is located in the path of the dog 22. TWhen the winding shaft 7 is rotated, the` armv 17 and the dog 22 move with the shaft in a counterclock-wise direction (Figure 2)', the

concaved inner edge 53 of the dog ridingover the finger 31 on the arm 30 of the guard 23, and the dog swinging upwardly on its pivotal mounting 23, the spring 25 being pnt under tension. As soon as the point of the dog has passed the linger 31, the dog swings downwardly under the effect of the spring- 25. until the projection 24 on the dog engages the arm 17 and stops the downwardly swinging movement of the dog. rThe dog 22 then' is so positioned that, whenthe arm 17 and the dog swing clock-wise (Figure 1), under conditions to be explained hereinafter, the convexed outer edge 26 of the dog will cooperate with the finger 31 of the Yguard 28. The arm 17, 'moving in a counterclock-wise direction with the winding shaft 7 (Figure 2), ultimately comes into engagement with the stop 20, but the operator may con tinue to rotate the shaft 7. and to wind the clock, because the arm 17 is connected to the shaft 7 with a frictional hold, the spring 19 (Figure 3) pressing the arm against the shoulder 11i on the shaft 7.

lVhen the pressure in an inward direction on the winding key. is relieved, the key is carried outwardly off the shaft 7, by the spring key-ejector 15 assisted by the spring 16 (Figure 3).

As the clock starts to run down (Figure 1), the shaft 7 rotates clock-wise, the arm 17 and the dog 22 moving clock-wise until the arm engages the stop 21. Thereafter, the shaft 7 rotates in the arm 17, the arm being frictionally held upon the shaft. The point of the dog 22 passes beneath the finger 31 on the guard 28, and the convexed outer edge 26 of the dog cooperates with the finger to raise the guard, until the opening 29 in the guard no longer registers with the opening 1Q in the case 1, and until the guard is interposed between the squared end of the windingl shaft 7 and the opening 11 in the rear wall of the case 1, it being impossible then to wind or set the clock.

lhen the guard 28 is raised, as aforesaid, the bell crank lever 32 is swung` on its fulcrum 33, the upstanding member of the bell crank lever moving in the direction of the arrow A in Figure 1, until the upper end of the said member cooperates with the stop 84. As the detent 13 moves in the direction of the arrow A in Figure 1, the dcl'ent rides along a portion of the lower edge of the arm 36 of the latch tilts the latch on its fulcrum 38 and engages behind the end of the arm 36, as depicted in Figure 2, the parts being restored to the positions shown in that ligure, thus to remain until another coin 5() is inserted into the coin chute a and the clock rewound.

In Figure 2, the coin 50 is shown filling the coin slot t transversely. The machine, however, may be operated by means of a smaller coin, simply by inclining the casing with respect to the vertical, in the direction indicated by the arrows B in Figure 2. and permitting` the smaller coin to roll along the inner edge of the coin slot l, over the projection 39 on the arm 37 of the latch 25.

lVhat is claimed is 1, A clock` comprising a winding shaft; a

respect to the shaft; an arm frictionally held on the shaft to swing when the shaft is rotated in opposite directions; means for stopping the arm to permit the shaft to rotate therein; a dog pivoted to the arm and slidable freely over a part of the guard when the shaft is rotated in one direction to wind the clocln the dog` engaging said part of the guard to move the guard to set posi tion with respect to the shaft and to engage the guard with the latch when the shaft rotates in a reverse direction as theclock runs down.

2. A clock comprising a winding shaft; a movable gnard for the winding shaft: coincontrolled means for releasing the `guard from set position with respect to the winding shaft; a resetting device coo} 3erating with the guard, and means for stopping the movement of the resetting device, the resetting device being frictionally carried by the shaft, whereby the shaft may be rotated independently of the resetting` device to wind the clockn and whereby the shaft may rotate independently of the resetting` device as the clock runs down, when the movement of the resetting device is stopped by the last-specified means.l

3. A clock comprising a winding shaft; a movable guard for the winding shaft; coincontrolled means for releasing the guard with respect to the winding shaft; and a resetting device for the guard, the resetting` device embodying an arm frictionally held on the shaft, a dog pivoted to the arm and movable freely over a part of the guard when the shaft is rotated to wind the clock. the dogl cooperating with said part of the guard to reset the guard with respect to the shaft as the clock runs down.

4t. Mechanism of the class described, constructed as set forth in claim 3, and further characterized by the fact that the dog is provided with a projection which, cooperating with the arm, limits the movement of the dog on the arm, and spring means cooperating with the projection to hold the projection yieldably engaged with the arm.

In testimony that we claim the foregoing as our own, we have hereto atlixed our signatures in the presence of two witnesses.
