MORRIS DENIS MONTECINO, OF SMOKE BEND, LOUISIANA.

AUTOMATIC-FIRE-ALARM ATTACHMENT.

Application filed July 29, 1916. Serial No. 112,077.

To all whom it may concern:

Be it known that I, Monnrs D. MoN'rn- GINO, a citizen of the United States, residing at Smoke Bend, in the parish of Ascension and State of Louisiana, have invented certain new and useful Improvements in Automatic Fire Alarm Attachments, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an automatic electric fire alarm and has for its object theproduction of a simple and efiicient means for closing an electric circuit after the temperature of the atmosphere surrounding the circuit closing device has reached a predetermined degree.

Fig. 2 is a side elevation of the structure shown in Fig. 1.

Fig. 3 is a rear elevation of the structure shown in Fig. 1.

Fig. 4 is a section taken on line 44 of Fig. 1.

Fig. '5 is a section taken on line 55 of Fig. 4, looking in the direction of the arrow. Fig. 6 is a section taken on line 55 of Fig. 1', looking in the opposite direction from the arrow.

Fig. 7 is a section taken on line 77 of 5 Fig. 8 is an enlarged section taken on line ss of Fig. 1.

Fig. 9 is a section taken on line 99 of Fig. 5.

Fig. 10 is a detail perspective of the contact block supported within the circuit closing casing.

Fig. 11 is a side elevation of the mechanism for closing the circuit for sounding a signal.

Fig. 12 is a detail perspective of the finger for closing the signal sounding circuit.

By referring to the drawings, it will be seen that 1 designates the outer casing of the indicator which is provided with a front cover plate 2. This front cover plate 2 is provided with a glass face 3 and an indicating face 4 is placed in the rear of the glass face 3. An indicating hand 5 is car-. ried by a shaft 6 which shaft 6 is supported within the casing upon the dial plate or indicating plate 4 as illustrated in Fig. 4t of the drawings and also passes through the supporting plate 7 ofthe bracket 8. The shaft 6 is provided with an enlarged portion 9 which enlarged portion 9 engages a thermostatic member 10, the thermostatic member 10 being in turn connected at its outer endto a blndlng block 11. This thermobracket 8 as clearly illustrated in Figs. 41. and 7 of the drawings.

A conducting arm 12 is connected to the shaft 6 so as to permit the shaft to readily rotate without swinging the arm 12, and this ari'n '12 is secured in an insulating bracket 13 as illustrated clearly in Fig. 41, the lower end of the arm being electrically connected to the conducting wire or other suitable cable 14 passing through the lower end of the casing 1. A contactarm or finger 15 is fixedly secured to the inner end of the shaft 6 and is adapted to rotate with the shaft 6 as the thermostatic member10 expands under the increase of temperature. It should be understood that as the thermostatic member 10 is acted upon by the different degrees of temperature that this spring will cause the shaft 6 to rotate due to the lineal expansion and contraction of the spring.

An'adjusting contact plate 16 is journaled in therear plate 17 of the casing 1 and this plate fits snugly against the plate 17 as clearly illustrated in Figs. 4.- and 5 of the drawings. A contact strip 18 is secured near the outer edge of this plate or disk 16 as is clearly illustrated by Fig. 5 and this strip 18 is adapted to be engaged by the con- Specification of Letters Patent. I Patentedsept. 3, 1918.

. static member 10 supported within the v The casing upon the topand bottom thereof, theftop eye I fitting over an arm 26 and the bottom eye the strip 18. An operating arm 23 is keyed to the sleeve 21 and may beswungso as to cause the disk 16 to be rotated to bringthe contact strip 18, attached to disk 16 as aforesaid, in the desired position to sound a signal oralarm at a predetermined degree of temperature. meral 2% is formed upon the'rear face of the casi'ng 1 so as to permit the operator to readily set the indicator or contact device for the desired degree.

1 is provided with an eye 25 fittingoveran arm 27. The top arm 26 is provided with an upturned end 28 and a seal '29 is adapted to pass through theouter end of the arm 27 so as to placement from the arms ZG and 27,

It, of course, should be understood that the circuit closing mechanism described and llustrated may be placed in any deslred. or conrenient position and that any suitable or convenient alarm or signal maybe electr cally connected thereto whereby this signal will be operated when the ten'lperature surrounding the circuit closer reaches a predetermined degree.

A dial indicated by the nu hold the casing .1 against accidental OldlllillltllOl'lZQd dis- For the purpose of convenience and illus tration, a .plurality of indicators above shown. or illustrated may be employed, wlnchmdicators are adapted to be placed upon each dwelling or; house in acertain' named locality for automatically electrically soundingv an alarm 1n case of fire 1n any one of these dwellings.

An alarm box of any ordinary type is ;adapted to cooperate with the electrical circuits above described, and a relay indicated by-ihe numeral 89 (Fig.11) is adapted to be placed 30 and 31 being connected to the binding posts 10, formed upon the sounder for energizing the electro-magnets 41, whereby armatureiZ will be actuated. The armature 42 carries a vertically-extending finger 43 (Fig. 11) which finger 43 carries, at its within said alarm box; the wires upper end, a contact fork 44 (see Fig. 12),

which contact fork ii has a ,conta ct wire 45 stretching between the fork ends of the member A rertically-extending standard 17 is .,1noi11itecl upon the base of the sounder-mom her. and carries a contact finger 428, which is electrically connected to wire as, and wire Copies of this patent may be iibtained f o'r 4:9, as well as wire 4-6 is adapted to be e1ectrically. connected to a general fire station or other general alarm.

;, What is laimed is:

1. An automatic alarm of the class described comprising a casing, a shaft supported within said casing, an indicating dial, a hand carried by said shaft and adapted to indicate the degree of temperature upon said dial,- a thermostatcarried by said shaft, acontact arm connected to said shaft, an electric circuit electrically connected to said contact-arm, an adjustable electrical contact mounted within said thermostat, said ad justable electrical contact comprising a disk journaled' upon said casing, an arm for facilitating the rotation of said disk, a con tact strip carried near the outer periphery of said disk and adapted to be -engagedby saidjc'ontact arm for closing a circuit'therethrough.

2. An auton'iatic alarm of the class described comprising a casing, a shaft supported within said casing, an indicating dial, ahand carried by said shaft and adapted to indicate the degree of temperature upon said dial, a thermostat carried by said shaft,a contact arm connected to said shaft, an adjustable electrical contact mounted within said thermostat, said adjustable electrical contact comprising a disk journaled upon said casing, 'n arm for tacilitating'the rotation of said disk, a contact stripcarried near the outer periphery of said'disk and adapted to be engaged by said contact arm for'closing a circuit therethrough, said contact strip provided with a stop knob at one end thereof.

3. An automatic firealarm of the class described comprising a casing, a contact arm, means for controlling the rotation of said contact arm, a second contact means comprising a disk, a contact strip carried by said disk and adapted to be engaged by said contact arm, an. indicator hand cooperating with said contact arm, a dial for said indicating hand, a second dial upon the rear face of said casing, an arm connected to said contact disk and adapted to permit said contact strip to, be set for contact with said contact 411 at a predetermined degree.
