Y'atented Apr. 20, 1920.

Application filedJune 28, 1.917. Ger-i211 No. 177,458.

T 0 all whom itmay concern Be it known that I. Fnnonn; ROSING BULL, citizen of Norway, and resident of Chris an Auguste gate 13. in the city of Christiania and State of Norway, have in vented certain new and useful Improvements in Saving-Clocks, of which the following is a specification.

Sic-called saving or econoinizing clocks have been in use for several years for the purpose of cashing savings. life-insuranc premiums or the like. The principle CO11- sists in this that a certain coin must be inserted into the clock in order to keep the latter oing. According to a previous construction the balance of the clocl: is caused to stop if the coin is not inserted regularly.

According to my present invention the stopping and releasing device is placed in connection with the wind-up of the clock so as to allow only a certain number of revolutions to be effected between each time the coin is inserted. The device is in other respects quite independent of the clock and is attached at the inside of the box or casing inclosing the clock and the money-box, so that the device may be easily shifted. if it is desired to vary the amount to be cashed by the clock.

The invention is illustrated in tie accompanying drawing, in which:

Figure 1 is a rear side view of an orninary alarm-clock nrovided with the savingdevice.

Fig. 2 is a detail view of the device showing the principal parts of the seen from a side opposite to that of Fig. 1 and in a somewhat modified construction and on a larger scale.

Fig. 3 shows a modification of the saving device; Fig. 4 shows the disk supporting frame from the side opposite to that in Fig. 3.

-1- is the clock. 9rits inclosing casing 3 the space for receiving the money-box (not shown), lthe wind-up shaft end of the clock. -5 a rear plate mounted upon the clock or casing. and --6- a frame plate forming the suoporting member of the saving device. The plate 6- supports pivotally two round disks,-7, 8, each of which has on its circumference notch 9, l0, respectively and also gear wheel -11, 12- respectively intermeshing with each other. -13 is a pawl arm pivotally attached at 16 to the plate -6 and provided with two pawls -1d, 15 adapted to engage the said notches 9, 1)- respectively. Th number of teeth of the wheels 11, 12- is so arranged that the wheels, only aft r a definite number of revolutions of the wind-up shaft i or wheel -1:2, will obtain such a position in relation to the wheel 11,thatthe pawls i l, 15 are able to engage their respective notches 9 and 10 simultane ously and thereby to bar the rotation of the wheels. consequently also of the shaft l.

According to Fig. 2 of the drawings the teeth numbers of the wheels -12 and ll are 23 and 2 i respectively. Consequently the notches 10, 9- will obtain the same relative position only each time the wheel 12 has made 24 revolutions.

The disk 7- has a recess -l7 forming a rest for the coin --l.8 to be insorted.

As soon as the pawls en their notches. the parts are positioned as shown in the drawing If now a coin 18 is inserted :eceived in the recess -17, whereby in is just in contact with the pawl --14-. Fince the notch -10- is somewhat larger than the width of the pawl 15, the disk 8 can be rotated through a small angle. During such rotation the coin 18 operates the pawl 1 l lifting the pawl. arm -l3 thereby disengaging the pawls -14, 15- from their notches 9, 10, so that the disks may now be further rotated. .i ifter a half revolution of the disk 7'. the coin -18 falls down from the recess 17 into the money-box, and the shaft 4-- can be rotated the definite number of revolutions (in the present example 24) before such rotation is stopped by the pawl. whereafter a new coin must be inserted again.

Instead of projecting the shaft 4 through the disk 8-. the latter may be simply provided with a square hole --l'i through which the clock windingdrey must be inserted in order to reach the said shaft.

In the modification shown in Figs. 3 and 4 the several parts corresponding to those shown in Figs. 1 and 2 are indicated by the san. e reference numerals, hence no special de scription of these parts will be necessary.

Instead of providing the coin-rest 1.7 on one of the disks as shown in Fig. 2, according to Fig. 3 the coin-rest 1'?" is here arranged upon the pawl arm -13, the latter being in addition provided with a stop -19. The coin -18 falls down between the arm -13 and a fiat spring --20 attached to the inside of the casing 2. The coin is held in the position shown in Fig. 8, thus forming a transmitting member between a push button -21' and the pawl arm 13, disengaging the pawls 1 1, 15 when the button 21 is pushed in from outside. In other respects the operation is just the same as described with reference to Fig. 2.

Having now described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. Stopping and releasing device for saving-clocks comprising two rotatable notched disks, one being operatively connected with the win l-up of the clock, intermeshing gear wheels having a differentnumber of teeth and attached each to one of said disks, a pawl arm, two pawls carried thereby, each pawl being arranged to engage the notch in one of the said disks, when the latter assume a definite mutually relative position, and a coin-rest so disposed that a coin supported thereby will operate as a medium for transmitting a releasing movement to the said pawl arm.

2. A stopping and releasing device, as specified in claim 1, having in combination with the coin-rest on the pawl arm and means for holding the coin in. place a push.- button operable from the outside and so arranged relative to the said pawl arm that upon being pushed inwardly, it moves, through the medium of the coin, the pawl arm so as to disengage the pawls.

3. A device as specified in claim 1, in which a spring is provided for holding the coin'in operative position on the coin-rest formed on the pawl arm.

Signed at Christiania and State of Non way this 19th day of May A. D. 1917.
