Specification ofLetters Patent. Patented J an. 14, 1913.
Application filed November 11, 1911. Serial No. 659,793.
To all whom it may concern:
Be it known that I, ROBERT FY E, a citizen of the United States, residing in the city of St. Louis and State of Missour1,-have 1nvented new and useful Improvements-5m Burglar-Alarms, ofwhich the following The present invention-relates. to certain novel and useful improvements in burglar alarms, and haspartiCular application to a device of the class described designed to be attached-or fastened to a window or door, transom or other opening, so that'should the window or door be forced by a person making an unlawful entrance, a cap such as a paper or a detonating cap will be discharged, thereby giving an alarm.
In carrying out my invention, it is my purpose to providea device which will embody in its construction a, cap holding plate or portion and a spring actuatedhammer,
the tendency of thespring being normally to throw the hammer into firing' position. Furthermore, I provide suitable means for holding the hammer in cooked or elevated position, ready to be released-when the door or window. is open.
It is alsomy purpose to provide a device of the class described, which will-embody the desired features ofjsimplicity, chea-pness -With the above-recited objects, and others of a similar nature in view, the invention consists in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claim.v
In the drawings :-Fignre 1 is a .view of a window, showing my device applied thereto. Fig. 2 is a view inside elevation, showing the hammer in elevated 01' cocked position ready to be discharged. Fig. 3 is a top plan view of the device. Fig, 4 is'a view of a. .portion of the door and transom, showlng I the manner of applying thedevice thereto.v
for the passage of screws or other means by Y which the device is secured. In F 1g. 1, I have shown the device as applied to the top portion of the'lower sash. Extend-mg upward at each side of the base plate and at approximately the center thereof, are the lugs 5-5 carrying the pivot bolt 6 upon which is pivotally mounted the hammer 7, the latter having a'striking proection or portion 8,. while the numeral 9 7 indicates a lip forming the end portion of the hammer and projecting. beyond the striking surface. The base plate is preferably provided with a cap, pan or rest 10,
-while the numerals 111l indicate. small lugs or ribs for retaining the cap in position.
The numeral 12 indicates a spring coiled about the pivot pin and having oneof its free ends l3jbearingagainst the hammer, while the opposite end 14; bears against the base plate. it will be seen that the normal tendency of the spring is to force or throw the hammer into firing or discharging position. At the rear end of the base plate are the lugs 16-16 to which are connected the endsl717 of the wire yoke 18, the latter terminating in an eye portion 19. vThe yoke is adapted to be thrown or hooked over the lip at the end of the hammer for the purpose of holding. the latter back in position ready to tire and against the tension of the spring.
The mimeralQO indicates a wire, cord or chain, one end 21 of, which is fastened 'in Fig. l 'to the bottom of the upper sash, the
opposite end of the wire being provided".
with a short cross bar '22 which is adapted to he slipped through --the eye at the end of the yoke.
In Fig. 4, the device is secured to the door D while one end of the wire is fastened to the transom E.
;Fr'on1 the above description, taken in connection with the accompanying drawing,
. the construction and manner of employingthe invention will be readily. apparent.
A detonating or other cap F is applied upon the firing pan, and the hammer. forced backward against the tension of the spring and held in, such position by means of the yoke. The cross bar is now run through the eye at the end of the yoke, so that the latter is connected to such wire which, as above mentioned, is in turn secured to the door or 1191i .10 exceedingly simple yet efficient form of alarm which may be readily placed upon.
Wire or cord will draw the window. Should an attempt be made to enter through the door or Window, by opening the same, the pull 'or tension upon the yoke from its locking position, thereby causing the spring to act and cause the hammer to fly backward, striking and discharging the cap, thereby giving warning or frightening away the intruder. 4
It will be noted that I have provided an Windows, doors, transoms or other openings.
It will further be-understood that during the day or at times. when it is not desired to set the alarm, it may be disconnected from the eye of the yoke so that the door or Window may be moved without causing the device to discharge.
.I claim z p A device of the class'described comprising a base plate, a cap pan mounted thereon and provided Withribs to retain a detonating cap within the pan, a pair of spaced parallel lugs extending from said base plate, apivot extending between said lugs, a hammer upon said pivot,"a spring encircling the tremity upon the hammer andhaving its opposite extremity in engagement with the base plate and normally tending to throw the hammer into firing position, a yoke pivoted to the base plate and adapted to engage the hammer to hold the same linelevated or cooked position, and a flexible element -adapted to be fastened at one extremity to the object to be protected, a cross bar connected to the opposite extremity of said flexible element and detach'ably associated with said yoke.
In testimony whereofI afiix my signature in presence of two Witnesses.
ROBERT FYFE. I Witnesses:
CHARLES SHAUGHNESSY, H. A. HAMILTON.
