SDEGIFIGATION forming part of Letters Patent No. 240,340, dated April 19, 1881.

Application filed January 3, 188i.

'To all whom it may concern:

Be it known that I, ALGERNON D. SMITH, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Alarm-Olocks,of which the following is a specification.

My invention relates to those clocks which are provided with cases having two compartments, the upper compartment being in the body of the case, which is provided with a glass front, and thelower compartment in the base.

My improvement consists in isolating the alarm mechanism from the time-movement, so as to conceal it from sight, and prevent the timer from being affected thereby, and also to locate it in a position where the sound of the alarm will not be muffled. To accomplish this I place the alarm mechanism within an open compartment in the base, and construct the ease in a suitable. manner to permit the connection of the timer to the alarm by peculiar means, as hereinafter set forth.

The accompanying drawing is a partly-sectioned front elevation of a clock embodying my invention.

The case has two compartments, 1 2, in the body C and base 0, respectively.

The alarm-movement proper, A, instead of being located immediately below the timemovement A, in the compartment 1 in the body 0, and in full View through the usual glass pane or window, B, is located, as shown, within the compartment 2 in the base 0.

For suitable connection between the timer and the alarm, the customary trippin gwire, D, is greatly prolonged, so as to reach through an orifice, c, in the floor E, to the customary deg F or projection from the alarmpallet G. That the tripping-wire may be entirely or mainly hidden by the jamb of the clock-case, it is passed around a fair-leader or through an eye, H, secured to the inner wall of the body 0. Access is afforded to the winding-arbor J of (No model.)

the alarm either by providing an aperture, K, in the base-front for the insertion of a customary winding-key, or by prolonging the arbor outside of the base-front and providing it with a ring or knob for winding. By this means the usually cheap and somewhat unsightly works of the alarm-movement are effectually hidden from sight, and are, by the same arrangement, placedin a more useful and effective position for communicating the alarm, so that it no longer becomes necessary to leave the clock-dooropen all night for that purpose, or to open it for that of winding the alarm, and consequently the clock-work proper is better protected from dust. Another advantage of my improvement is the material reduction of the disturbing action of the alarm-movement on the timer.

The continuous wire connection renders the device wholly independent of the position of the clock as to exact verticality,so thatit' used with an eseapement-elock it can be set at any angle without destroying its efficiency.

I do not claim, broadly, the location of the alarm at or near the base of and away from the clock, but merely the specific improvement set forth and herein claimed.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

The clock-case consisting of bodyO, base 0, having key-hole K, and floor E, having opening 6, in combination with an alarm mechanism, A, in the base compartment 2, timemovement A in the body compartment 1, and the prolonged nearly or wholly concealed tripping device D, connecting the timer with the alarm, as set forth.

In testimony of which invention I hereunto set my hand.

ALGERNON D. SMITH.
