FIRE-ALARM.
SPECIFICATION forming part of Letters Patent No. 286,393, dated October 9, 1883.
Application filed May 3, 1883. (No model.)
and useful Improvement in Fire-Alarms; and
I do hereby declare that the following is a full, clear, and exact description of the same, ref erence being had to the accompanying drawings, forming part of this specification, in which 7 Figure 1 is a side elevation, partly in section, of my improved fire-alarm; and Fig. 2is a central section of tube E.
Similar letters indicate like parts in both the figures.
My invention relates to improvements in electrical fire-a1 arms for hotels an d other buildings; and it consists in the peculiar construc tion and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claim.
In the accompanying drawings, A repre sents a curved arm secured to the wall of a room just over an ordinary electric push-button, B.
C represents a sleeve fitting over an d adapted to slide on the curved arm A, and provided at its upper end with the weight D.
E represents a tube secured to the wall of a room near its ceiling, to the interior of which is secured by a composition, F, that melts at 150 Fahrenheit, or at a low temperature, an interior concentric tube, c. a represents a wire connecting theinterior tube, 6, with the weighted sleeve C D. Should a fire occur in the room, the cement would melt and allow the interior tube, (2, to fall, whereby the weighted sleeve C D would be carried around by gravity on the curved arm A, so as to come in contact with the push-button B, thereby closing the circuit and giving the alarm at the office.
Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-
The combination, with the curved arm A and push-button B, secured to the wall of a room, of the weighted sleeve C D, wire (1, and tubes E 12, secured by the composition F, substantially as described, and for the purpose set forth.
FREDERICK A. COPELAND.
