BELL FOR ALARM-CLOCKS.

SPECIFICATION forming part of Letters Patent No. 617,184, dated January 3, 1899.

Application tiled September 19, 1898. SerialNo. 691,286. (No model.)

T0 all whom it may concern:

Be it known that I, WILSON E. PORTER, of New Haven, in the county of New Haven and State 'of Connecticut, have invented a new Improvement in Bells for Alarm-Clocks; and I do herebj7 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 rear View of a clock having my improved bell applied'thereto; Fig. 2, a sectional view on the line a b of Fig. l.

This invention relates to an improvement in clock-bells, and particularly to such as are employed in alarm-clocks having round sheetmetal cases and in which the main and alarm winding arbors and means for setting the hands and alarm, as well as the bell-hammer, project through the rear wall of the case, although the bell is equally applicable for other styles of clocks.

It is desirable that bells for the class of clocks above specied should be as large as possible, and it is also desirable that they should be arranged in a plane parallel with the plane of the back, so as to be conveniently packed for transportation. For this purpose gon gs comprising a flat disk and an inwardlyturned flan ge have been provided and formed with holes or openings in the disk for access to the winding and setting mechanism. As is well known, in a bell of this character the metal inside a band, near the outer edge of the disk, does not effect the ringing qualities of the bell.

The object of this invention is to construct a bell having the iiange portion and so much of the central portion as is necessary for the proper support of the bell; and it consists in the construction as hereinafter described, and particularly recited in the claims.

For convenience of illustration I have shown my improved bell applied to a clock of ordinary construction and comprising a circular sheet-metal caseA, in which the movement is mounted and through the rear wall B of which project the hand-setting key C, main-winding key D, alarm-winding key E, alarm-set F, and hammer-shaft G, on which the hammer H is mounted, all as in the usual construction, and in which the rear edge of the shell or case A projects beyond the rear Wall B. The bell consists of a dat ring I, formed with a flange J at right angles thereto, which iiange is slightly less in diameter than the diameter of the wall B, so as to freely set inside the rear edges of the case A. The inner edge K of the ring I is bent inward in an inclined plane and at one or more points is formed with a projection or tongue L, which extends downward to a point below the edge of the flange, and thence is turned into a plane at right angles thereto or t in a plane parallel with the plane of the ring,

and this tongue is secured to the rear wall B of the clock-case or to some other convenient point. In sheet -metal clocks as herein shown it may be-desirable to reinforce this wall by a transverse plate B', which may be brazed or otherwise secured to the inner face thereof.' This tongue L, while herein shown as projecting inward, may be bent in a reverse direction or .otherwise inclined to accommodate itself to the location of the support to which it is to be secured, and, as be fore stated, more than one tongue may be provided should occasion require. The inclined inner edge K of the ring is so short that it will not interfere with the vibration of the hammer H, which, passing beneath this edge, is free to strike the ringing-ange J, as clearly shown in Fig. 2. It will thus be seen that a large bell is provided and practically the entire surface of the rear wall ex posed, so that the mechanism extendingv IOO is held away from but adjacent thereto, and in close proximity to the bell-hammer, substantially as described.

In testimony whereof I have signed this specification in the presence of two subsorib ing Witnesses.

VILSON E. PORTER.
