ALARM-CLOCK.

Specification of Letters Patent.

Patented lvlay '7, 1907.

Application filed September 4. 1906. Serial No. 333.111.

To 1.11/7 w/wm, it may concern.-

Be it known that we, ELMER E. SrooKroN and ARTHUR 'H. PORTER, citizens of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, l'iave invented a new and useful lmprovement in Alarm-Clocks and we do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1 a plan view of a nickel alarmclock constructed in accordance with our invention. Fig. 2 a view of the clock in vertical flatwise section on the interrupted line ab of Fig. 3, looking into the front of the clock upon the dust-guard which is exposed by the removal of the bell. Fig. 3 a view in vertical crosswise section on the irregular line c-d of Fig. 2.

Our invention relates to an improvement in nickel alarm clocks, so called, this name having long been applied by the trade to small alarm clocks in circular nickeled sheetmetal cases. In recent years these clocks .have been provided to a large extent with concentrically arranged bells located at the back and perforated for the passage of the winding and setting arbors. Such clocks are objectionable in so far as the bell is exposed, and as they call for long winding and setting arbors, and special packing boxes, all entailing extra expense.

The object of our invention is to obviate these objections and to produce a simple,

compact and effective clock in which the bell is completely protected, and in which the back of the clock is left as in nickel alarm clocks having the bell located on top of the case.

With these ends in view our invention con sists in locating a concentric bell entirely within the clock case and in certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out our invention, I employ a bell 2 arranged concentrically within the circular case-body 3 and located at a point between the dial 4 and. the front plate 5 of the clock-movement which may be of any ap proved construction and is not shown beyond its said plate 5, its rear movement-plate 6 and its pillars 7. These parts sufficiently show its position in the case-body and its relation to my present improvement.

To permit the sound of the bell to escape, we form a series of perforations in the case in proximity to the bell. As shown, these perforations take the form of a band of circular holes, but it is not necessary that there should be a continuous band of perforations, or that they should have one form rather than another. Nor is it essential that they should be used at all, but by preference they will be used in some form or other.

The hell 2 rests upon a circular bearing face 9 forming the truncated top of large concentric conical boss 9 struck forward from the center of a circular sheet-metal dust-guard 10 corresponding in diameter to the internal diameter of the case-body 3 and designed to prevent any dust that may work through the perforations 8 from getting into the movement which is located entirely back of this guard. As shown, the bell is secured to the said guard 10 by means of three fixed screw studs 10 carried thereby and receiving nuts 11 which bear upon the outer face of the bell, as shown in Fig. 2. These screw studs are made just right in length to support the center of the dial 1 as also shown in Fig. 2.

The dust-guard itself is fastened by screws 12 or by rivets as the case may be, to the radial inner ends of three stiff sheet-metal strap- like feet 13, 14, 15, employed to position and hold the movement in the case-body 3. The upper strap 13 is secured. by a rivet 16 directly to the front movement plate 5, while the lower straps 14- and 15 are riveted to the forward ends of the two lower pillars 17 of the movement. These feet extend horizontally forward at their outer ends and are attached to the case-body 3,-the upper foot 13 by the stem 18 of the handle ring 19,

and the feet 14 and 15 by the turned peglike feet 20 and 21. At their extreme forward ends the feet are bent inward to form bearing-flanges for supporting the dial L which is held in place by a bezel 23 supporting a glass 24 held in place by turning in= ward the forward edge of the case-body 3 to form a retaining flange 25. A clearance opening 25 is formed in the dust-guard 10 to permit the hammer 2 and hammer-tail 23 to reach forward from the clock-movement TOO to the bell. The back 29 of the case fits into the open rear end of the ease-body 3 in the usual way.

By locating the bell eru' irely within the case-body, we conceal and protect it and restore the exterior form of the ease to its original aspect. We also avoid making the winding and setting arbors of the expensive and ineonvenien t length demanded when the bell is located on the back of the case, and also reduce the mutilation of the hell itself to the mininmm. :l urthernmre our improved clocks do not require the special boxes called for when the bell is at the back.

1. ln an alarm clock, the combination with a circular case-body formed with perlbrations, of a movement and a dial, a concentrically arranged bell located between the dial and the front of the movement, and a dust-guard located within the case in front of the movement to isolate the same from the perforations in the case.

2. In an alarm clock, the combination with a circular case-body, of a movement, a dial, a concentrically arranged bell located between the front of the movement and the dial, and a lust-guard located between the hell and the movement and supporting the 0 bell.

ln an alarm clock, the combinaiion w'th a circular body, of a movmnent, feet attached thereto for positioning the same within the case, a dial, a dust-guard applied to the said feet, and a concentrically arranged bell located between the dust-guard andv the dial and carried by the said guard.

4:. In an alarm. clock, the combination with a circular case-bod y, of a movement, a. dial, a dust-guard, a concentrically arranged bell located between the dial and the dustguard, and screw studs mounted in the dustguard and supporting the said hell and also supporting the central portion of the dial.

5. In an alarm clock, the combination with a sheet-metal ease-body formed in its ftn'ward portion with perforations, of a movement, a bell located within the casebody adjacent to the said perforations and in front of the said movement, and a dial formed independently of the bell and located in front of the same.

in testimony whereof, we have signed this specification in the presence of two subscribing witnesses. 4
