CLOCK.

fSIPEGIFICATION forming part of Letters Patent No. 541,207, dated June 18, 1895.

Application filed April 26, 1894. Serial No. 509,056. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES A. JACQUES, a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Clocks, of which the following is a specification.

My invention relates to clocks and has for its object to provide the same with means for giving an alarm at difierent predetermined recurring intervals during a predetermined period of time, and to this end my invention consists in providing suitable tripping devices or their equivalents which will be driven by the clock to trip or set oli' the alarm at predetermined recurring periods. This mechanism I denominate a repeating alarm.

I attain the object of my said invention by the mechanism described herein, illustrated in the accompanying drawings, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a rear view, partly broken away, of a clock having one form of my invention applied thereto. Figs. 2 and 3 are detail views of the spring-barrel for propelling the alarm. Fig. l is a plan view of a suitable gear for transmitting movement from the center pinion of the clock to the tripping-wheel of the alarm. Fig. 5 is a side view of the construction as represented in Fig. 1 looking in the direction of the arrow 5, some of the parts being omitted for clearer representation. Fig. 6 is a similar view taken in the direction of the arrow 6, some or" the parts being omitted, as before. Fig. 7 is an enlarged plan view of the. tripping-wheel. Fig. 8 is a rear view of a clock, showing my preferred form of tripping device applied thereto, the same consisting of a removable tripping disk or wheel preferably driven from the center pinion, as will be more fully hereinafter set forth. Fig. 9 is an edge view of the back plate of the clock shown in Fig. 8. Fig. 10 is a detail View of a single trippingdisk or wheel. Fig. 11 is a detail view of the train for communicating motion from the center pinion to the arbor of the trippingdisk. Fig. 12 is an enlarged detail view showing one method of removably attaching the tripping-disk shown in Fig. 10 to its arbor.

I will proceed to describe the mechanism shown in the accompanying drawings which show forms of my invention, without, however, limiting myself to the precise construction therein shown and described, as it is obvious that the devices and their construction and arrangement may be greatly varied without departing from the spirit of my invention.

In the drawings, A and B (see Fig. 5) represent the front and rear plates respectively of a clock movement.

0 represents the going-barrel or other suitable driving mechanism for the clock.

D represents the going-barrel or driving mechanism for the alarm train. The arbor d of the going-barrel has attached to it by one end a coil-spring a, the other end of which is attach ed to the goingbarrel in the usual manner. Secured rigidly upon the arbor d is a gear I) upon which the goingbarrel is mounted. From the gear I) motion is communicated to a suitable pinion c, (Fig. 1) upon whose arbor is carried a ratchet e which co-operates with suitable pawl and ratchet mechanism to actuate a hammer fto strike a bell g or other audiblesignal. Theapparatuswhichhasjust been described is, however, the regular alarm. train and may, if desired, be omitted, the other train which will presently be described being capable of use as a regular set alarm. Mounted also upon the arbor (Z is a ratchet h with which co-operates a spring-pressed pawl 2' which is carried by a gearj loosely mounted upon the same arbor d so that when the arbor cl is turned in a direction contrary to the direction of the arrow 2, Fig. 2, to wind the spring a, the pawl will slide over the ratchet teeth and the gearj will remain stationary; but when the spring has been released, as will be described, the pawl locks the gear to the ratchet '2, and they both travel together in the direction indicated by the arrow 3 in Fig. 2.

Meshing with the gear j is a pinion 7a which carries also upon its arbor a gear is which meshes with a pinion k which carries on its arbor ratchet Z which actuates a hammer on which co-operates with the bell g. Upon a rock-shaft 01 is mounted an arm 0 which cooperates with a stop disk 13 mounted on or driven from the arbor carrying the gear is. This disk is provided with a notch q in its circumference in which the toe of the arm 0 is adapted to be entered. Carried also upon the rock-shaft n is an arm 0' in the path of a tripping-lever 8 carried by a rock-shaft 25 upon which is also mounted a detent a (Fig. 1) which is adapted to contact with the trippingwheel, and normallyheld in such position by a spring m as will be more fully hereinafter set forth. Mounted also upon the rock-shaftn is an arm 4) which is adapted to co-operate with a pin to on the ratchet Z.

The mechanism last described constitutes a device for setting off the alarm, although this taken specifically, may be varied, as I may use any suitable device for striking the alarm, which will vary under the varying conditions of practice.

The tripping-wheel is built up of a pile of tripping-disks E carried by a suitable arbor, as 00. These disks are provided with one or more spurs e, which are spaced around the periphery of the disks so as to engage with the detent u at predetermined intervals during the rotation of the tripping-wheel.

It will be observed that the detent u is of such width as to engagewith the spurs onbut one disk at a time, and as the spurs are spaced around the periphery of each disk to come opposite the detent at different recurring periods, some means must be adopted for raising and lowering the tripping-wheel to bring the desired disk into position for engaging the detent by means of its spurs. This mechanism I have shown as a lever y pivoted in a stirrup 2 having one end engaging under the tripping-wheel to raisethe same, and its free end engaging under a cam cylinder a or other cam device, which can be turned by means of a button I) to depress the free end of the pivoted lever y, and to cause the same to lift the tripping-wheel to any predetermined or desired extent to bring any desired disk in position to operate the detent a. This tripping-wheel is loosely carried upon the arbor as so as to be movable longitudinally thereon, but at the same time to be rotated thereby.

Mounted rigidly upon the arbor 0c is a gear 0' with which meshes a gear (1 (Fig. 4) which in turn gears with the center pinion f of the clock. Thus, the tripping-wheel is driven by the rotation of the center pinion, but this tripping-wheel may be driven from other moving parts of the clock, if desired. This center pinion makes one rotation in one hour and the gearing is so cut and proportioned as to cause the trippingwheel to make one rotation in every four hours. Now, if it is desired to actuate the repeating alarm once every four hours the buttonb is manipulated so as to bring the tripping-disk having but a single spur in position for engagement with the detent Lt. If, however, it is desired to actuate the alarm twice in'four hours, the disk having two spurs is brought into position for engagement,-it being well understood, however,- that instead of a pile of disks, a'cylinder provided with pins may likewise be used with good effect.

In Figs. 8, 9, 10, 11 and 12, Sheet 2, I have shown a modification illustrating the pre- 'ferred form of my, invention, usings'imi-lar suitable receptacle F provided centrally with a post for the accommodation of the spare disks; that is to say, the disksithat areanot in 1 use. I may also be removed by removing the bracket The disks E shown in Figs. 5, 6 and 7 Z and unstepping the arbor w. The disks are therefore removable in'both the preferred and modifiedform, although, if found desirable, the disks of either construction may be rigidly secured to their arbor. v

, The operation of my device is asfollowsz The clockwork being in motion, at the proper predetermined time, a spur e will come in contact with thedetent tathereby rockingthe rock-shaft t against the tension of its spring m. WVhen the spur has-passed ofi of the detent, the spring will cause the rock-shaft to be swung back to'its initial position-,brin gin g the tripping-levers violently into contact with the arm 1", lifting the toe of thelever 0 out of the notch q in the wheel 19, also causing, the arm 2) to release the pin w on the ratchetl. The alarm mechanism now revolves freely and causes the hammer m to strike the bell.

The toe of the arm 0 resting on theface-of the disk 19 while the same is revolving, thus-holds the arm 11 away from the ratchet 70. When, however, the notchin the disk 1) comes under the toe of the arm 0, the said toe willdrop into the notch again, thus rockingthe rock-shaftn to causethe arm 11 toengage the pin-w, thus locking the alarm mechanism by bringing. the

arm 1; intothe path of the pin to again. This operation is repeated as often as a spur comes in contact with the detentu, and by bringing.

spurs in contact with the detent u the alarmmay be given at predetermined times: which,

as will be recognized, is especial-1y valuable where medicine hastobe ad ministered-at predetermined times.

What I claim, and d'esireto secure by Let ters Patent, is- 1. In" an alarm clock, the combination of amain driving train, an alarm train with me-- chanical releasing means therefor, tripping disk or disks interposed and forming mechanical connection between the main train and the mechanical releasing-means for said alarm train, and an adjusting. device for moving, said disk or oneof said disks in the directionof its axis into position to move the-alarm releasing mechanism, whereby the alarm can be operated at different predeterminedrecurring intervals, substantially as described.

2. In a clock, the combination of an alarm, releasing mechanism therefor, a cylindrical tripping-wheel mounted in proximity to the releasing mechanism, and means for adjusting the tripping wheel longitudinally of its axis and for holding the same in its adjusted position, whereby the alarm can be operated at dilterent predetermined recurring intervals, substantially as described.

3. In a clock, the combination of an alarm train, mechanical releasing mechanism therefor, a cylindrical tripping-wheel, a pivoted adjustinglever engagingtherewith,andacam device engaging the free end of the pivoted lever, whereby the tripping-wheel can be moved and different portions of the working face can be brought in line with releasing mechanism to move the same, substantially asdescribed.

4. In an alarm clock, the combination of an alarm train, releasing mechanism therefor, a spring actuated rock-shaft, an arm upon the rock-shaft adapted to release the alarm train, a detent on the rock-shaft, and a tripping device for moving the detent to rock the shaft against the tension of the spring, whereby when the detent has been released from the tripping-wheel the shaft will be rocked to move the arm carried therebyinto engagement with the releasing device by a sudden positive movement, substantially as described.

5. In an alarm clock, the combination of an alarm train, releasing mechanism therefor, a spring actuated rock-shaft, an arm upon the rock-shaftand adapted to release the alarm train, adetent on the rock-shaft, and a tripping wheel for moving the detent to rock the shaft against the tension of the spring, whereby when the detent has been released from the tripping-wheel the shaft will be rocked to move the arm carried therebyinto engagement with the releasing device by a sudden positive movement, substantially as described.

6. In an alarm clock the combination of a main driving train, a main alarm connected with and released thereby, and a second or auxiliary alarm also connected with the main driving train and released thereby at recurring intervals between the time for which the main alarm can be set, substantially as and for the purposes specified.
