ALARM-CLOCK.

Specification of Letters Patent.

Patent-ed Apr. 11, 1911.

Application filed. October 15, 1910. Serial No. 587,220.

To all whom it may concern:

Be it known that we, ELMER E. STOCKTON and ARTHUR H. PORTER, citizens of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement 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, 1n

Figure 1 a view in front elevation of a clock constructed in accordance with our invention. Fig. 2 a broken perspective view of the lower end of the clock. Fig. 3 a view thereof in vertical central section.

Our invention relates to an improvement in metal-cased alarm-clocks. Such clocks have generally been known as nickel alarms for the reason that for many years they have been placed upon the market in nickeled sheet-metal cases, generally cylindrical in form.

The object of our present invention is to produce at a low cost for manufacture, a simple and attractive alarm-clock having an upright sheet-metal case and constructed with particular reference to fewness of parts and convenience of being assembled and dismounted.

With these ends in view, our invention consists in a clock having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out our invention as herein shown, we construct from a strip of sheetmetal, a case-body having a rounded top 2,

straight sides

3, 3, and a horizontal base 1, which latter is formed, as shown, with two large sound-

holes

5, 5. Obviously, however, the case-body might be made pointed or polygonal at the top instead of round, and its base might be provided with a number of small sound-holes instead of two large ones, these. being matters of design. Upon its forward edge, the case-body is provided with an integral inwardly turned bead-like flange 6 forming a stop for the flat case-front, which consists of a single piece of sheet-metal conforming to the shape of the case-body and adapted in size to fit snugly within the same so as to bear against the stop-flange 6 before referred to. The upper portion of the case-front 7 is formed with a large dialopening 8 outlined by a struck-up head 9. The said case-front 7 is held against the flange 6 and so positioned within the case, by means of a dust-guard 10 struck up from a piece of sheet-metal and projecting forward from the flanged sheet-metal case-back 11 to the lower end of which it is fastened by screws 12. This dust-guard is formed upon its forward edge, with two depending bearing-arms 13 and with two depending bearing-fingers 14 which yieldingly press against the case-front 7 and hold the same in position. The said dust-guard 10 carries the bell 15 which is suspended from its lower face on a stud or post 16 and struck by means of a hammer-head 17 carried by a hammer-wire 18 passing through a clearance slot 19 in the guard 10. The guard, as it may be here explained, prevents dust or any foreign matter which may enter the case through the sound-holes 5, from rising into the clock-movement 20 from which dust is thus entirely excluded except such as may work up into the case through the clearance-slot 19 before mentioned. The clock-movement 20 may be of any approved construction and adapted to sound either a long or an intermittent alarm or both, and does not need detailed illustration or description, since any moiement of approved construction may be use To the front movement-plate 21, we attach a sheet-metal ring 22 which provides a mounting for the glass 23, the dial-mat 2%, the dial 25, and the dial-back 26, however these parts may be constructed. As herein shown, the dial 25 and mat 2d are made from a single piece of sheet-metal, the numerals representing the hours being produced by perforating the metal of the dial proper and emphasized by a dial-back 26 of contrasting color. As shown, the ring 22 is formed with forwardly extending fingers 27 which are clasped over the edge of the glass 23 which in turn rests upon the flanged outer edge of the mat 2 1 the inner edge of which terminates in the dial 25 which rests upon the dial-back 26, which in turn rests upon the flanged forward edge 31 of the ring 22 as clearly shown in Fig. 3. By means of the construction just described, the glass, dial,

dial-mat and dial-back are assembled together independently of the case and connected with the movement so as to be removed from and replaced in the clocl-z-case therewith. The sheet-metal case-back 11 is adapted to fit within the open rear edge of the said case-body to which it is secured by screws 28. The entire case is supported, as shown, upon four small balls 29, the pair in front being secured to the base l of the case-body and the pair at the rear passing through the said base into the lower flange 30 of the case-back 11. By removing the ap propriate screws, and the rear pair of balls 29, the case-back 11 together with the movement, dial, dial-glass, dust-guard and bell may be withdrawn from the casebody, as one piece, and restored, as one piece, to posi tion within the case-body, whereby the clock is made very easy to assemble, and dismount for attention and repair.

lV e claim 1. In an alarm-clock, the combination with an upright case-body formed at its forward edge with an inwardly turned stop-flange; of a flat removable case-front conforming to the case-body in shape and set within the same against the said stop-flange, a case-back adapted to be set within the rear open edge of the said case-body, a movement secured to the upper portion of the said case-back, and means independent of the said movement attached to the lower portion of the said case back and extending forward therefrom under the said movement to engage with the case-front for holding the same in place against the said stop-flange of the case-body.

2. In an alarm-clock, the combination with an upright case-body having a top, sides and base, the latter having sound-holes; of a flat removable case-front conforming to the casebody in shape and set within the forward edge thereof, a case-back, a movement attached to the upper portion of the said caseback, and a dust-guard attached to the lower portion of the said case-back and extending forward therefrom below the said movementand above the soundholes in the case of the case-body and constructed to engage with the lower portion of the said case-front for holding the same in place.

3. In a clock, the combination with an upright case-body formed at its forward edge with an inwardly turned stop-flange and having its base provided with sound-holes, of a flat, removable case-front conforming to the said case-body in shape and set within the same against the said stop-flange, a removable case-back, a clock-movement secured to the upper portion of the case-back, a dustguard located within the said case-body and secured to the case-back, and a bell located above the base of the case-body and suspended from the said dust-guard.
