ilNrTnD STATES PATENT @Tricia RUSSEL G. DUDLEY, OF JERSEY CITY, NEW JERSEY.
BURGLAR-ALARIVI.
SPECIFICATION forming part of Letters Patent No. 267,503, dated November 14, 1882. Application led June 17, 1882. (No model.)
To all whom it may concern:
Be it known that I, RUSSEL G. DUDLEY, a citizen ot' 'the United States, and a resident ot' Jersey City, in the county ot' Hudson and State of New Jersey, have invented a new and my device. Fig. 2 is a side view, in part sectional. Fig. 3 is a bottom plan View. Figs.
4 and 5 are detail views.
This invention relates to shutter-workers and burglar-alarms; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claim.
In the drawings, A indicates an ordinary window-shutter, and B the usual jamb or casing.
A bracket, C, secured to the shutter above its lower hinge, or formed'upon one of the leaves ot' the lower hinge, projects laterally from the shutter, and is connected with a jointed rod, D, by means of a link, E. This jointed rod slidesin an openingtbrmed through the window frame or casing, or in a tube inserted in said opening, and is provided with a knob, F, upon the end ot' its inner joint or section. The opening is enlarged laterally at the outer side of the frame, so that when the shutter is swung open the link can enter said enlarged portion ot' the opening, and Where the jointed rod slides in a tube the latter will have a slot, G, at its outer end for the passage `of the link when the shutter is swung open and the link turned at an angle to thejointed rod.
1t will be seen that when the shutter is open it can be readily closed by pushing the knob on the jointed rod toward the windowcasing.
Below the sill or upon the door or window, or in any other convenient locality, 1 arrange the alarm mechanism, which comprises a clock mechanism with a striking-hammer, a bell, H, and a device for holding and releasing the striking-hammer.
The clock mechanism herein shown comprises the usual spring, H', gear I, and springpawl and ratchet K upon the arbor carrying the spring, the said gear heilig arranged to engage a pinion upon the spindle L, carrying a spur-wheel, M, which actuates the pawl M. This pawl is fixed upon a rock-shaft, which latter carries the striking-hammer N. The spring is wound up in the usual way, anda spring, O, secured at one end and at its remaining epd connected with a wire or cord, P, is brought up against the striking-hammer to prevent the same from acting. The springis thus brought against the hammer by drawing upon the cord, and itis maintained in such position by means of a stop, It, which is engaged with 'the window-frame. This stop consists of a pin, r, which is inserted in an opening in the framejust above the knob, and a plate, r, which, when the knob is pushed up to the frame, lies against the face of the knob. If,now,.theshutterisopened,thejointed rod will be moved back and the knob disengage the stop from the frame, whereby the spring will free the striking-hammer and thus allow it to vibrate and strike the bellor gong, which Will be sounded and give notice that the shutter has been opened. After the jointed rod has been pushed back to its farthest extent, its innerjoint or section will drop down alongside of the frame.
lThe alarm mechanism can be inclosed in any suitable box or case conveniently located.
A. jointed rod working in an opening in the casing of a window and connected to the hinge by a linkis not new, and is not broadly claimed herein.
Having thus described my invention, what I claim is- The combination, with the sliding rod connected by a link or joint with the shutter, of the alarm mechanism provided with a bell or gong and a striking-hammer, a device for holding and releasing the hammer, and a stop connected with said holding and releasing device, and adapted to be engaged with the window-frame and broughtinto Contact, when In testimony that I claim the above I have hereunto subscribed my naine in the presence so engaged, with the knob on the inner end of of two witnesses.
the sliding rod, whereby when the shutter'is swung open the knob will disengage the stop, and the hammer be thereby released, substantially as described.
