Patented Aug. 9, 1921.

UNITED STATES- PATENT OFFICE.

PAUL LUX, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE lLUX CLOCK MANU- FACTURING COMPANY INC., 03 WATERBURY, CONNECTICUT, A CORPORATION OF CONNECTICUT.

ALARM-CLOCK.

Specification of Letters Patent.

Application filed April 19, 1921. Serial No. 462,551.

To all whom it may concern 7 Be it known that I, PAUL LUX a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Alarm-Clocks, of which the following is a specification, reference being had therein to the accompanying drawing. I a v This invention relates to certain new and useful improvements in alarm clocks and more particularly to the bell arrangement forthe same, the object being to provide a concealed bell alarm employing a fiat gong in connection with avnovel construction of hammer and means for operating the same i: f the clock so that the head will strike against the metal gong plate whichis disposed between theclock movement and the back of the case.

Another and further object of the invention is to provide a novel form of support for the hammer wire in the form of a bracket in which the hammer wire is loosely mounted, one end of the same being provided with a rightangled bend working in an opening formed in the hammer tail lever, the size of the opening of which controls theendwise movement of the hammer wire in the bracket 7 which provides a very simple and cheap construction of alarm and one which is very efiicient ineuse.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a rear elevation of an alarm constructed in accordance with my invention showing the gong plate in dotted lines;

Fig. 2 is a top plan view; s

Fig. 3 is a detail perspective view of the hammer wire bracket, hammer wire and hammer tail lever detached; and

Fig. 4 is a detail top plan view of a slightly modified form of mounting the gong plate.

In carrying out my invention I employa front frame 1, a back frame 2 connected together by the usual pillars 3 and having an alarm main spring 4 and a winding key 5.

The frame is provided with the'usual alarm maln wheel 6 which meshes with a pinion 7 carried by arbor 8, said arbor having an alarm crown wheel 9 which is engaged by an alarm verge 10 in the usual manner and while I have only shown certain elements of the alarm clock, it is of course, understood that inuse clocks constructed as now generally in use are'employed having the regular time control mechanism so as to cause the alarm main wheel to rotate.

The back 11 of the case carries bell posts 12 on which is mounted a flat gong plate 13 disposed between the back, of the case and the clockwork and adapted to be engaged by the hammer as will be later'described.

Secured to the back frame 2 is a hammer wire bracket 14: in which is loosely mounted a hammer wire 15 having a head 16 capable of engaging the gong plate 13. The other end of the hammer wire 15 is bent at right angles as shown at 17 forming an angled end which extends through an opening 18 formed in a hammer lever 19 carried by the the alarm verge, the endwise motion of the hammer tail wire being controlled by the opening in the hammer lever and as the verge imparts an up and down movement to the hammer lever, the hammer wire 15 is oscillated so as to bring the hammer head intermittently into engagement with the gong plate 13 to sound an alarm.

It will be seen that by this construction a very novel form of hammer and hammer tail is provided in connection with a novel form of hammer tail lever which allows the parts to be readily assembled in a very economical way.

In the modification shown in Fig. 4 the back frame 2 carries bell posts 20 for supporting the fiat gong plate 21 in such a position that it can be engaged by the hammer and I do not wish to limit myself to the particular manner of mounting the fiat gong plate as I am aware that the same can be mounted in various ways without de arting from the spirit of my invention. 11 both forms I have shown the same disposed between the clock movement and the back of the case and when arranged 111 this manner it will be in position to be engaged by the hammer head of the alarm mechanism and it will be seen that by this construction I have provided a concealed bell alarm for alarm clocks composed of a very few parts so arranged and assembled that a very ethcient and economical construction is provided.

In the application of my improved construction of alarm for clocks, the back or use is perforated in order to allow the sound waves to pass out of the case and I do not wish to limit myself to the use of my improved construction of alarm to any particular construction of case as I am aware that *arious constructions can be used without departing from the spirit of my invention.

What I claim is 1. The combination with an alarm clock having an alarm main wheel and an alarm crown wheel for actuating the alarm verge, a gong disposed between said clock work and the back of the case a hammer wire carrying a hammer said hammer wire having an angled tail and a hammer tail-lever carried by said alarm verge having an opening to receive the angled hammer tail for causing the hammer to be oscillated.

2. An alarm clock having a flat gong plate disposed between the clock work and the back of the case and a hammer arranged to engage said gong plate.

3. An alarm clock having a gong disposed between the clock work and the back of the case and a hammer wire havin a head at one end an a hammer tail at the other end provided with a horizontal motion at right angles to the back of the clock, said hammer tail being actuated by a hammer tail lever for causing the hammer head to be intermittently brought into engagement with the flat gong plate.

An alarm clock having a frame, a bracket carried by said frame, a hammer wire loosely mounted in said bracket provieed with a hammer head at one end and a hammer tail at the other end and a l1ammer tail lever provided with an opening arranged to receive the hammer tail wire for causing the hammer head to move at right angles to the back of the clock and a gong disposed parallel with the back frame of the clock adapted to be engaged by said hammer head.

5. The combination with an alarm clock having the usual time control mechanism including an alarm verge, a lever carried by said alarm verge provided with an opening, a bracket having a hammer wire loosely mounted therein provided with an angled end working in said opening, a hammer at the opposite end of said hammer wire and a plate disposed to be engaged by said hammer head.

6. in alarm clock comprising a frame ada; ted to be inelosed in a case, a gong disposed between the back of said case and said frame, said frame containing time control mechanism includiman alarm verge, a bra ket carried by said frame, a hammer wire mounted in said bracket having a head at one end and an angled portion at its other end and a hammer tail lever carried by said verge provided with an opening to receive the angled end of said hammer wire for causing said hammer to move at right angles to the back of the clock and engage the metal gong plate.

In testimony whereof I hereunto aflix my signature.

PAUL LUX.
