ELECTRIC SWITCH CLOCK COMBINATION Filed March 25, 1936 2 Sheets-Sheet 2 INVENTOR.

634/? NOS/64 L Patented May 11, 1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to apparatus for causing an alarm to be given at any predetermined hour at which it may be set.

An object of the invention is to provide means, combined with a clock mechanism, whereby the clock is caused to repeatedly sound an alarm at intermittent intervals until manually interrupted.

A further feature is in the provision of means for causing a light to appear simultaneously with the ringing of the audible alarm.

Another purpose is to produce a device which may be used in store windows to switch on or oil electric lights at a predetermined hour automatically.

These advantageous objects are attained by the novel construction and combination of parts hereinafter described and shown in the annexed drawings, forming a material part of this disclosure, and in which:-

Figure 1 is a rear elevational view of a complete embodiment of the invention as assembled ready for operation.

Figure 2 is a top plan view thereof.

Figure 3 is a partial side elevational, partial sectional view, the section being taken on line 3--3 of figure 2.

Figure 4 is a diagrammatic view of the electrical circuit.

Figure 5 is a plan view of a modified form of 1 the adjustable control device.

By reference to the drawings, the device will be seen to consist of a platform l5 having an upright support l6 at one edge, in which is set an alarm clock I! of conventional type, its face being disposed outwardly.

The rear side of the clock is provided as usual with a winding key 18, hand setting knob 19 and alarm setting knob 20.

The winding key for the alarm has substituted for it, a key 2| having a lengthening stem and the striker or bell hammer 22 extends through an opening in the circular casing of the clock.

Fixed on the casing, adjacent the striker, is a bracket 23 carrying a pivot 24 on which is mounted a lever 25, its front end extending into position to intercept the striker 22 under certain conditions, while its rear end is engaged by a link 26 connecting with the outturned end of an upright lever 21 pivoted at 28 to a bracket 29 on the base I5 and urged outwardly by a spring 30 coiled around the pivot.

A plate 33 is held against the upright It by a clip 34 at its lower edge, and mounted on the plate is a circular insulating housing 35 held by screws 36, the housing having a cover 31, this housing containing -a snap switch of any preferred well known commercial type, provided with a spindle 52 having an actuation knob 56.

The spindle 52 is further guided by an adjustable bracket 54 carried on a support 55 fixed on the plate 33.

Fixed on the spindle 52, adjacent the outer end of the cover 31, is a spur gear 51 meshed with a pinion 58 rigidly mounted on the stem of the winding key 2! (see Figure l) which is. adapted to convey motion to the spindle 52.

A control disc 62 is provided with. a pair of opposed arcuate slots to receive bolts 6| by which it is adjustably secured with the gear, the disc having in its periphery two opposed notches 63 each of which is adapted to receive the lug 32 of the lever 21 and, by reason of the shape of the notches, force thedug outwardly as the disc 82 is rotated.

Current is conveyed from any convenient source, as the battery 65 or plug 56 through conductors 61-458 to the terminals 50, one of the wires being tapped as at 59 to provide current v to a light bulb l0 controlled by a switch 1| while the circuit is wholly under control of the main switch 12 as previously described.

In addition, a signal in the form of a lever I3 is pivoted to the plate 33 and provided with limiting stops l4 and I5 fixed on the plate, the func tion of the lever 13 being merely to indicate whether the circuit be closed or open, the lever being settable by hand for this purpose.

- The modification shown in Figure 5 consists of a disc having arcuate slots -8| adjustable on the pins BI and has a greater number of recesses 82 in its periphery than in the disc 62, thereby reducing the time intervals in which the alarm is given. I v

In operation the clock alarm is set at any desired hour and its spring actuating mechanism wound as usual, it being understood that the electrical connections have been made.

When the hour arrives at which it is desired to have the alarm operate, the pinion 53 rotates the gear 51 and disc 62, which, at intervals receives the lug 32 into the notches 63, moving the lever 25 to intercept the striker 22, thereby causing the alarm to cease and also to open the switch mechanism'whereby the light ceases to glow.

The lug 32 is however moved outwardly to ride on the periphery of the disc, releasing the lever 25 and permitting the alarm to operate, at which time the light I0 is caused to glow.

Althou h the improvements have been described with considerable detail and with respect to certain particular forms of the invention, it

made without departing from the spirit and scope of the invention in its broadest aspect.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:

1. In combination, an alarm clock having a striker and a winding key therefor, a pinion on said key, a gear meshed therewith, a disc having notches in its periphery fixed on the side of said gear, a lever having a lug enterable in the 5 notches of said disc, said lever being spring pressed against the disc, and means actuated by said lever to control the action of said striker.

2. In combination, an alarm clock having a striker and a winding key therefor, a pinion on 20 said key, a gear meshed therewith, a disc having notches in its periphery adiustably fixed on the side of said gear, a spring impelled lever having a lug to engage the notches of said disc, a switch controlled by said disc, said switch being in circuit with a source of electric energy, a light bulb in said circuit, and means combined with said lever for releasing and restraining the action oi said striker and for opening and closing said switch.

3. 1m combination, an alarm clock having a striker and a winding key therefor, a gear train driven by said key, a notched disc actuated by said train, a lever spring pressed against said disc, said lever being moved by contact therewith, means associated with said lever to control the movements of said striker, an electric circuit including a lighting means, and a switch in said circuit controlled by said disc.
