UNITED STATES' FREDERICK J. T. HALLOF AKRON, OHIO.

COMBINED ALARM CLOCK AND LAMP.

Application filed February 24, 1927. fierial No. 170,640.

This invention relates to alarm clocks and has special reference to a combined alarm clock and lamp.

One important object of theinvention is to provide a novel and eflicient device wherein a circuit will be established for an electric lamp or light at the same time that the usual ringing alarm is sounded, the device being of novel and improved character.

A second important object of the invention is to provide improved circuit closing means whereby the lamp may be lit or extinguished independently of the alarm.

A third important object of the invention is to provide an improved circuit closing means actuated in a novel manner by the hammer of the alarm. 7

With the above and other. objects in view as will be hereinafter apparent, the inven: tion consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a front elevation of a combined clock and lamp constructed in accordance with this invention.

Figure 2 is a rear elevation thereof.

Figure 3 is a detail side view with a portion of the casing broken away, the view being to enlarge scale.

Figure t is a similar rear view.

Figure 5 is a plan view, certain ofthe parts being omitted.

Figure 6 is a wiring diagram of the device.

In the embodiment of the invention here shown the usual clock work is employed in theclock but only such parts of the alarm system of the clock work are shown as bear directly on the invention the remalnder being omitted in order to avoid confuslon between the usual clock work parts and the invention itself. Bearing this in mind it will be seen thatthere is provided a clock casing 10 of ornamental form and on top of this casing is supported the usual socket 11 for an electric lamp 12 protected by a shade 13. These parts may be made of any de-' sired form or degree ofvornamentation and I am not confined to the exact form or shape here shown. Within the casing 10 is mounted an alarm hell or gong 14 adapted to be struck by a hammer 15 carried by an anchor escapement l6 operated by a star wheel 17 in the usual manner. The driving train and timing mechanism for the alarm are, as above noted, not shown but are of the usual well known construction. WVithin the cas- 111g 10 is mounted a pivot 18 whereon is piv oted a lever 19 carrying at one end a hammer head 20 which lies in the path of the head of the hammer 15 as it rebounds from the bell 14. The other end of the lever 19 is provided with a counterweight 21 so that thehead 20 swings easily when struck by the hammer 15. The arm 19 oscillates be tween stops 22. From theback wall of the casing 10 projects a bracket 23 whereon is centrally pivoted a lever 24 carrying plunger buttons 25 which project through the rear wall of the casing 10. Also on this rear wall is an insulated bracket 26 which carries a contact 27 engageable by a contact carried by one of the buttons 25, this last contact being located on the button which is pushed in to light the lamp. The other button 25 lies in the path of the head 20 and, when the light is off, is pushed in so that when the alarm goes off the head 20 will be thrown against this last button and push the same out thus moving the other button in and closing the contact 28 on the contact 27.

From the contact 27 a wire 29 leads to the lamp 12 and from this lamp a wire 30 leads to a suitable source of power here indicated as the battery 31 although, obviously, usually connection will be made to the house lighting circuit. Similarly thebracket 23, which is in conductive relation with the contact 28, is connected by a wire 32 with the source of ower.

Thus wiienever the alarm goes off the light circuit is closed and the lamp will be lit also at any time desired the lamp may be turned on or off by manipulating the buttons 25* in the usual manner.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without'departing from the material spirit thereof. Itis not, therefore,

desired to confine the invention to the exact desired to include all such as properly com within the scope claimed.

Having thus described the invention, what is claimed as new, is:

1. In a combined clock and lamp, an alarm mechanism including a hammer, a lamp and circuit therefor, a switch positioned adjacent the hammer and adapted for operation through movement of said'han'imer, and a swinging member suspended between the switch and hammer and having a head engaged by the hammer upon actuation thereof, said head engaging the switch to close the same upon actuation by the hammer.

2. In a combined clock and lamp, an alarm esa n2 mechanism including a hammer, a lamp and circuit therefor, a switch positioned adjacent the hammer and adapted for operation through movement of said hammer, and a swinging member suspended between the switch and hammer and having a head engaged by the hammer upon actuation thereof, said head engaging the switch to close the same upon actuation by the hammer, said switch being normally free from the head to permit manual operation thereof independently of the movement of the head.

in testimony whereof I afiix my signature.

FREDERICK J. T. HALL.
