Description
UNITED STATES JOHN F. COPIOCK, OF VVESI` NEWTON ASSIGNOR TO JOSEPH D. VINNEDGE,
OF INDIANAPOLIS, INDIANA.
IMPROVEMENT IN BURGLAR-ALARMS.
Specication forming part of Leiters Patent No. 137,532, dated April 8, 1873; application filed December 23, 1872.
To all whom lit may concern:
Be it known that I, JOHN F. GoPPooK, of West Newton, in the county of Marion and State of Indiana, have invented certain Improvements in Burglar-Alarms, of which the following is a specification:
My invention consists in the arrangement and inode ofoperatingaburglar-alarm, consisting ot' a bell to be attached to the windowsashes of dwellings and other buildings in such a manner as that any cha-nge in the position of the sash will cause the bell to be rung, and thus sound the alarm to the inmates.
A B B represents the frame and lower and upper sashes respectively of a Window. The construction and arrangement of the alarm is represented in section. C is the casein which the bell-hammer D is pivoted, and the spring E arranged by which the hammer is caused to strike the bell, as hereafter explained. The case is attached by means of screws through iian ges, at the bottom, to the upper or meeting rail ofthe lower sash, as shown. The bell F is attached to a rod, G, projecting from the case. Any one of the upright bars of the upper sash, or, in cases where the sash is filled by a single sheet of glass, either ofthe stiles, is furnished with a ratchet-bar, H. The case, of course is to be attached to the lower sash opposite toV It is obvious from this arrangement that, if
the lower sash is raised or the upper one pulled down, the hammer J will be tripped and the bell rung.
The same device may be attached to doors by attaching the ratchet to the casing and arranging it so that it may be turned to one side during the day, or at such times as the alarm is not required.
The alarm is applicable to sashes hung in any of the ordinary modes.
I claim as my invention- The burglar-alarm consisting of the case C, supporting the bell F, and the hammer D J, with spring-arm E I, in combination With the ratchet-bar H, all constructed and arranged substantially as and for the purpose set forth.
JOHN F. COPPOCK.
