ALARM ATTACHMENT FOR OVERFLOW-BA SINS.

SPECIFICATION forming part of Letters Patent No. 357,307, dated February 8, 1887.

- Application filed March 25,1886. Serial No. 196,511. (No model.)

To aZZ whom it may concern:

I ment to be applied tothe overflow-basins of refrigerators and to similar purposes. The alarm is constructed in such a manner that when water accumulates to a certain height within the basin it will raise afloat and thereby liberate the mechanism which sounds abelL- The invention consists in the various features of improvements hereinafter more fully r by lugs e,cut out from the body of plate 11 and aresecured by means of rivets or solder. The

plate 0 is provided at its top with a hook, f, by which it may be suspended over the edge of a basin, A. At its bottom the plate 0 has a nose or noses, g, to hold. it in an upright position.

.h is a spindle passing through and having hearings in plates a b. This spindle is surrounded by a coiled band-spring, Z, one end of which is attached to the spindle, while the other end is attached to a fixed drum or shell secured to the front of plate a. By revolving "the spindle the spring is wound up.

The spindle h, to which one end of the band-spring'i is attached, carries gear-wheel j, giving motion to said wheel j through an ordinary connection, such as a ratchet-wheel carried by the spindle and a click carried by the gearwheel, as soon as ratchet-wheel k is relieved, when said gear-wheelj revolves the ratchet-wheel k through an intermediate cogrevolution of the ratchet-wheel causes the hammer to be swung outward (to the left in Fig. 3) as a tooth of the wheel bears against the shoulder Z. liberated'the weighted head a causes-the hammer to swing back, and thus a rapid reciprocating motion is imparted to the hammer.

0 is a float pivoted to plate 0 by means of an arm having a downwardly-curved catch, This catch bears against one side of a pin, q, attached to head a and projecting through a slot of plate, I).

1' is a bell against which the hammer strikes.'

The operation of the'device is as follows: The clock-work being wound up, the appasuch a way that the float 0 projects into the basin. The float is now in its lowermost position and the catch 19 is opposite the pin q and locks the clock-work. As soon as the float 0 has risen by an accumulation of water (dotted lines, Fig. 1) the catch 19 will swing down and the pin qwill thus be liberated to permit the clock-work to move the hammer and to sound the alarm;

' I claim as my invention 1. The combination of bell r and plate 0 with spindle h, hammer m, having shoulder Z and pin q, and with float o, catchrp, gearwheel j, ratchet-Wheel 7c, and spring "Z, substantially as specified.

2. The combination of bell r and plate 0, having hook f and nose 9, with float 0, catch 10, hammer m, pin q, spindle h, spring 2', gearwheel j, and ratchet-wheel k, substantnally as specified.

3. The combination of hell 1' and float 0, having catch 1), with hammer m, having weighted head n,.pin q, and shoulder Z, and with spindle h, gear-wheel j, and ratchetwheel 70, that engages shoulder Z, substantially as specified.

4. The combination of plates at b c with spindle h, gear-whee1 j ratchet-wheel k, spring i, hammer m, having shoulder Z, head a, and pin q, and with bell r, float 0, and catch 19, sub: stantially as specified.
