ALARM-WATCH.

Speciication of Letters Patent.

Patented Mar. 4, 1919.

Application led November 21, 1917. Serial No. 203,174.

To all whom 'it may concern.'

Be it known that I, CHRISTIAN EDMUND- soN, a citizen of the United States, residing at Tientsin, China, have invented certain new and useful Improvements in Alarm- Watches, of which the following is a specification.

This invention is an alarm watch and has for its principal object the production of a device which will sound a signal at a desired hour.

Another object of this invention is the production of anV alarm watch wherein one of the hands will close a circuit at a desired hour for automatically sounding a signal.

Another object of this invention is the production of an alarm watch which has a plurality of insulated sockets carrying circuit terminals, while a plug is also provided having fingers to fit within the sockets for allowing a circuit to be formed at apredetermined hour, according to the sockets in which lthe fingers are inserted. Y

With these and other objects in view, this invention consists of certain novel combina-k tions, constructions, and arrangements of parts as will be hereafter fully described and claimed.

One practical form of construction and assembly will be described and illustrated Y in the accompanying drawing in which- Figure 1 is top plan view of the alarm watch as constructed in accordance with the present embodiment,

Fig. 2 is a fragmentary side elevation of the alarm watch, portions of the retaining strap being shown in section, and n 3 is a diagrammatic view of the wirino system of the present invention.

" lliteferring to the accompanying drawing by numerals, it will be seen that 1 indicates the watch casing, which may be provided with any suitable operating mechanism for driving the hands 2 and 2. Frames 8 are formed on the casing 1 in diametrically opposite positions, as shown in Fig. 1. The retaining strap 4 is passed through the frames 3 and bears upon the casing 1 as illustrated in Fig. 2. It is of course obvious, that this strap 4 may be provided with a buckle 5 at one end toreceive the opposite end 6 of the strap, whereby the watch may be retained upon the wrist of the wearer.

The contact posts 7 are arranged in pairs upon the dial of the watch, wherever it is desired or any hour or fraction of an hour as isllustrated in Fig. 1. The contact posts 7 have wires 8 extending therefrom and connected to the sockets 9, which sockets may be suitably insulated from the casing 1, if so desired, as is shown in Fig. 1. These sockets 9 are arranged in pairs and spaced relation upon the peripheral side of the watch, as shown in Fig. 2.

1t is of course obvious that any suitable form of a signal may be employed in connection with the present invention although a pair of bells 10 are mounted upon the strap 4 and these bells are obviously of the usualmagnet type of an electric bell as is clearly shown in Figs. 1 and 2.

` connected to one pole of the bell. as shown at l13. The conductor 14 leads from the same pole and is connected to the pole 15 of the remaining bell. The conductor 16 leads from the remaining pole of the last mentioned bell and is connected to the pole 17 of the first mentioned bell. A conductor 18 leads from pole 17 and is connected to the linger 19 carried by the plug body 20. This plug body 20 is of course formed of suitable insulating material, as is clearly shown in Fig. 3. f The plug body 20 is also provided with a second finger 19 projecting therebeyond as the finger 19. The conductor 21 leads from the linger 19 and is connected to p forth it is obvious that the watch may be retained upon the wrist of the wearer in the usual manner. If it is desired to have the signal sounded at a certain hour, for in- 5 stance as at 5 oclock, the plug body 2O is moved to the necessary point for permitting the projecting ends of lingers 19 and 19 to be passed into the sockets 9 corresponding to the hour the signal is to be sounded. Thus 10 it will be seen that the fingers 19 and 19 will be connected by the conductors 8 to the contact posts 7. When the hour hand finally engages the contact posts 7 it will close the circuit, thus causing the current to pass from the source of supply 11 over conductor 12 to the pole 13. A portion of the current will also pass over the conductor 14 through the bell 15 and return over conductor 16 to the pole 19. Therefore, the two bells will simultaneously ring. The current will pass from pole 17 over conductor 18 through finger 19 and the Wires 8, as well as the hour hand 2. The current returns through finger 19 and conductor 21 to the source of supply 11, thus causing the bells to ring as long as the hour hand remains in engagement with the posts 7, at the hour the alarm is sounded, or until the plug has been removed from the selected sockets, which of course will break the circuit.

In order to change the hour when the signal is to be sounded, it is only necessary to withdraw the fingers from the sockets by the removal of the plug 2O from engagement with the periphery of the casing 1. The cables 18 and 21 are of sufiicient length to permit the plug to be moved at any place desired from the periphery of the casing` as it is necessary to perform this function in order to allow the signal to be sounded at different hours. By moving the plug around the periphery of the casing the fingers may be inserted in selected sockets in a manner similar to which they are inserted in the sockets adjacent the hour 5, as shown in Fig. 1.

From the foregoing description it will be seen that a very efficient alarm watch has been provided since the watch may be strapped upon the wrist of the wearer without interference from the alarm attachment therefor. The signal may be changed so as to be sounded at a desired hour, as has been hereinbefore described, and at the time desired, the circuit will be closed by the engagement of the hour hand with selected contact posts thus causing the bell to ring until the hour again disengages the contact posts. It is of course obvious that many detail changes may be made in the construction of the present invention Without departing from the. spirit of the device, such for instance as placing the sockets upon the dial rather than upon the periphery of the casing as shown and for this rea-son it is not intended to limit the construction of the present invention to the specific form herein shown but to include all such forms of the alarm watch properly coming within the scope of the device as claimed.

What I claim is 1. In a device of the class described, the combination of a watch having alined frames formed on its periphery, a retaining strap extending across the back of the Watch and extending through said frames, said strap having a longitudinal passage extending therethrough intermediate its ends, bells fixed upon said strap, adjacent theframes, conductors connected to said bells and extending through said passage, thus providing an even wearing surface upon the outer surfaces of the strap, and means for closing the circuit over said conductors at a predetermined hour for ringing said bells.

2. In a device of the character described, the combination of a watch, including hands, wires carried by said Watch, contact posts connected to said Wires in the path of movement of one of the hands, sockets connected to the remaining ends of said Wires, signal means carried adjacent said watch and means removably fitting within selected sockets for closing a circuit at a predetermined hour, when one hand engages certain of the contact posts.

3. In a device of the character described, the combination of a watch having Wires connected to contact posts, said Watch having hands, said posts being in the path of movement of one of said hands, sockets connected to said wires, bells connected to said watch, conductors connected to said bells and including a source of energy, a removable plug consisting of a body having independent iingers extending therebeyond, said fingers also being connected -to said conductors, whereby the projecting ends of said fingers may be removably carried within selected sockets, thus causing a circuit to be closed at a predetermined hour when one of said hands engages the binding posts corresponding to the sockets carrying the fingers of said removable plug.
