DETONATING BURGLAR ALARM.
UNITED STATES PATENT OFFICE.
WILLIAM NOBLETI, OF CHICAGO, ILLINOIS.
DE/TONATING BURGLAR-ALARM SPECIFICATION forming part of Letters Patent No. 287, 85C, dated November 6, 1883.
Application filed March 30, 1883. No model.)
To all whom it may concern.-
Be it known that I, WILLIAM NOBLETT, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Burglar-Alarms, of which the following is a specification, to wit:
This invention relates to an improvement in burglar-alarms; and it consists in the combination and arrangement of parts, whereby, when a door or window is opened 'a cartridge is exploded, substantially as will be hereinafter more fully set forth and claimed.
7 In order to enable others skilled in the art to which my invention relates to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawing, in which is represent ed a vertical section of my invention.
A represents a box or case, in which is removably secured a steel block, B, through which is bored a hole, B, adapted at the inner end to receive a cartridge, as represented in the drawing. Upon one side of the hole B, at the inner end, is pivoted a trigger, 0, one arm of. which is connected to a cord or wire, 0, extending through the block or, case to the outside. The other arm of this trigger is adapted toextend under the free end of the firing-spring D, secured at the other end to the block B, and arranged, to lie across the cartridge, at which point it is provided with a firing-pin, d, to explode the cartridge.
This device issecured in any convenient position with relation to a door or window, and 35 the wire 0 secured to it in such manner that s the door or window, when partly opened, will the firing-pin may be so placed as to form a ,1
rim or center fire.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a burglar-alarm, the combination, with 5 the case A, of the removable block B, formed with hole B, the trigger 0, having cord or wire 0, and the firing-spring D, provided with the firing-pin d, all constructed and arranged to operate substantially as and for the pur- 5 poses herein set forth.
In testimony whereof I affix my signature in presence of two witnesses.
. WILLIAM NOBLETI.
