UNIT D STATES GEORGE w. buses, for BRUNSWICK, MAINE.-
FIRE-ALARM.
SPECIFICATION forming part of Letters Patent No. 278,586,'-dated May 29, 1883.
Application filed February 8, 1883: (No model.)
To all whom it may concern:
Be it known that I, GEORGE W. NAsoN, a citizen of the United States, residing at Brunswick,.in the county of Cumberland and State of Maine, have invented a new and useful Fire-Alarm, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to fire-alarms, and has for its object to provide asimple and effeptive device arranged to be secured to the walls of a room or to the wall decorations, and go give an alarm when it comes in contact with p In the drawings, Figure l is a perspective view of my device arranged in position on.the Fig.2 is a longitudinal sectional view Fig. 4. is a rear view of a picture-frame to which the alarms have been applied.
Referring to the drawings, A designates a' simple cylinder or tube having disks B inserted in its ends to close the same, said disks being provided with perforations U, the purpose of which will be presently described. a
D is the fuse, which extends longitudinally through the tubeA andpasses through the perforations C, so that its ends E project from the end of the device. The tube is to. be charged with powder or some other explosive material, and after. the disks are secured in posimm, with the fuse in place, the whole device is to be covered with an outside wrapper, F, which is preferably ornamental, and this wrapper extends aroundthe projecting end E of the fuse, as at G, and is secured thereto by any. suitable adhesive substance, or other means whereby it retains the fuse in position.
H is a strap by which the tube can be suspended in position. This strap is secured to the tube by means of a strip, I, that is provided with adhesive substance on its under surface, and is attached to the tube, with the end J of the strap between the tube and its under surface; 1 i
The charged tubes are to besecured in ornamental manner around the walls or cornice it of the room or other place liable to fire, and
they can also be arranged out of sight on articles of household furniture or decoration, such as the picture shown in Fig. 4 of the draw ings. As soon as fire touches any end of the fuse it is instantly communicated to the explosive substance inside the tube, and the latter is exploded with a loud report to alarm the inmates of the house. These tubes will occasion no inconvenience at any time, and are perfectly harmless until they come in contact with fire.
I am aware that-devices of this class have 6;:
been heretofore constructed of a shell charged with explosive material and having afuse projecting from disks at its ends, a covering being wound around the projecting end of the fuse, and the tube being suspended as desired. 6
I therefore makeno claim to this, broadly, my claim being for my own novel construction and arrangement of parts, in which a longitudinal fuse is passed loosely through the perforations in the end disks, and is secured in pogeneral wrapper, and by reason of this arrangement and construction the device p0ssesses superior advantages in point of simplicity and efficiency, and can be manufac- 8o tured at a minimum expense. The fuse is'secured merely by the permanent wrapper at its ends, which, being light, is quickly destroyed when the end of the fuse becomes ignited,
when the portion of the fuse passing through 8 the disk will be readily consumed, as the fuse is not secured in the perforation inthe disk, but simply passes through the same If the fuse were secured in position by fixing it in the disk, the ignition would be slow through 0 this portion, and would in some cases be completely destroyed; but my improved manner of securing the fuse and construction entirely obviates any of these disadvantages and pro duces a simple and very efficient device. 95
I claim as my invention- I As an improvement in fire-alarms, the com-- bination of the tube arranged to contain an The longitudinal fuse having its ends passing diand the suspending-strap secured'to the tube 10 rectly through the perforations in the disks at outside the said Wrapper, as set forth.

same, and also projecting around the project- GEORGE W. NASON; ing ends of the fuse, and permanently pasted or Witnesses: otherwise secured to the same to retain it in F. H. STONE,
position and from longitudinal displacement, R.D. OARVILL.
