CIRCUIT-CLOSER.

Specication of Letters Patent.

Patented Jan. 22, 1907.

Application filed December 16,1905. Serial No. 292,031.

To rzZ/f whom, it muy concern.'

Be it known' that I', ERNEST SEYMOUR CLAYTON, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Circuit- Closers, of which the following is a specication.

My invention relates to circuit-closing devices, and has for its. object to provide an improved device of this character; and to theseendsit consists in a device embodying the various features of construction and arrangement of parts having the mode of operation substantially as hereinafter indicated.

A preferred embodiment of my invention accompanying drawings, in which- Figure 1 is a side View illustrating myimproved circuit-closer applied to a float; Fig. 2, a plan of Fig. l. Thecircuit-closer ma be used in various constructions, one of which is illustrated in Figs. 1 and 2. ln Figs. 1 and 2 is shown the for use where it is desired to indicate the discharge of a body of water into a receptacle J, which may be a tank of any'suitable character.

To insulated terminals K K of the tank are connected the wires" of an, electric circuit, and to each terminal is also connected a spiral spring H, which at its outer cnil is in cleci trical connection with a platinum terminal F, extending through a block of glass closingr the mouth of a small glass or vitreous bulb or receptacle D, and this in turn is inclosed withina larger bulb or iloatA, andthe joints sealed to,prevent the access oi' air, moisture, or dust. Within the bulb l) is a movable metallic contact-piece C, preferably in the form i of a globule of mercury.

The springs'lfl tend to hold the parts in a horizontal position, in which case the contact C is carried away from the terminals F L said but when the water rises in the tank the receptacle will swing about its fixed support at the side of the tank and the parts take the position shown in Fig. 1, when the contact C is brought against both terminals F, completes z the circuit, and `sounds an alarm through the medium of any suitable alarm devices, (indicated at M.)

It will of course be understood that by lproperly arranging the parts the device may e used where it is desired to sound an alarm upon the discharge ofthe water from the tank. The construction shown in Figs. 1 and 2 is especially adapted for use in connection with the chamber Oi a dry-pipe valve of a re-extinguisher system, where the parts may be inoperative for many years and Where it is especially desirable thatthere shall be no failure to operate under the contingency where water is discharged into the tank, and it will be evident that whatever may be the length of time during which the parts are notin action there will be no deterioration of the ethciency of the circuit-closing devices.

Vithout limiting myself to the special construction and arrangement shown, I claim- 1. A circuit maker and breaker comprising,r a closed receptacle having terminals and a movable contact-picco withm the receptacle and 'flexible spring electric connections between the terminals and a source of electric energy, whereby the electric circuit is controlled by changes in position of the receptacle, permitted by the flexible spring connections.

2. The combination of a receptacle provided with separated terminals in electrical connrction with a generator and containing a movable contact-piece, and a float inelosing receptacle, substantially as and for the purpose set forth. v

In testimony whereof I affix my signature in presence or' two witnesses.,

ERNEST SEYMOUR CLAYTON.
