No. 527,527. Patented Oct. 16, 1894.
virus c UNITED STATES PATENT OFFICE.
JOSEPH F. GRAYBIIL, OF YORK, PENNSYLVANIA.
ALARM-LOCK FOR DOORS, 80G.
SPECIFICATION forming part of Letters Patent No. 527,527, dated October 16, 1894.
i Application tiled April 23, 1894. Serial No. 508,668. (No model.)
To a/ZZ whom, it may concern,.-
Be it known that I, JOSEPH F. GRAYBILL, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Alarm-Locks for Doors or Windows, of which the following is a specification.
My invention relates to alarm fastenings for windows and doors, and particularly to that class of fastenings which operate by exploding a detonating cap or cartridge when they are tampered with by unauthorized persons.
In the accompanying drawings, in which like reference signs refer to similar parts throughout the several views, Figure 1 is a rear view of the fastening as adapted to doors.
Fig. 2 is a horizontal section on the line 2--2- of Fig. l, showing the invention applied to a door. Fig. 3 is a similar view showing the door partly open. Fig. 4 is a front view of the detonating lock applied to a window. Figs. 5, 6 and 7 show end views of the same, the trigger of the lock occupying different positions, and Fig. 8 is a section on the line 8 8 of Fig. 4.
In the drawings, A indicates the detonating lock as applied to doors, and A the same as applied to windows.
B indicates a device to be applied to a door for the purpose of preventing the alarm from operating when the door is opened by persons properly authorized and in possession of the key.
The lock proper A, A consists of a casing l which is hollow and the outer wall of which is cut away at one end to form a side opening 2. At the base of the side opening there is a transverse wall or partition 6 which is perforated for the passage of a plunger 4. Upon one end of the plunger 4 is an arm 3 which serves the double purpose of a trigger for the alarm and a lock for the door or sash. The arm 3 is adapted to pass into the side opening 2 and to tit said opening in such a manner that it may not be turned while in it. The plunger rod 4`passes through the transverse partition or abutment 6 and carries on the end opposite the arm 3 a head 5. Between the head 5 and the abutment 6, there is conned a spiral spring 7 which tends to draw the arm 3 into the opening 2 with violence when the arm is brought opposite the opening. The detonating caps are placed upon the abutment 6 at the base of the side opening and there is preferably aloose plate 9 arranged adjacent to this abutment so as to form an apartment 8 to receive the caps.
As applied to doors, the lock is provided with a flange 10 having perforations for screws whereby it may be attached tothe door frame. The lock for Windows may be similarly attached to the lower rail of the upper sash, j
but in some instances I prefer the attachment shown in Figs. 4 and 6 so that the lock may be more readily removed for the purpose of cleaning the window. In these figures there is a plate 1l attached to the lower rail of the window-sash and in this plate there is a slot 2 which is narrow at one end and wide at the other similar to a key-hole. Upon the casing of the lock is a headed pin 13, the stem of which is flattened and lits the narrow end of the slot, and the head of which may be passed through the larger end of the slot. By using this connection the alarm lock may be readil57 connected to or removed from the window.
Fig. 6 shows the window fastening set as a burglar alarm it being understood that there is a detonating cap in the compartment S. As shown in Fig. 6 the trigger is drawn out and depressed so that it rests against a shoulder 14. (See also Fig. 4.) It will be evident that when the lower sash O is raised slightly, or the upper sash lowered the trigger will be released from the shoulder 14 and will be drawn violently against the plate 9 discharging the cap. At the same time the trigger will be confined between the upper and lower Walls of the side opening 2 and will form a positive lock for the window. When it is desired to lower the upper sash or raise the lower sash the trigger 3 can be thrown up resting against the shoulder 15 as shown in Fig. 7. Fig. 5 shows the position of the trigger when the window is locked.
In using my alarm lock in connection with doors, I provide a movable rest which can be operated by a knob or key to carry the trigger over the side opening 2 when it is desired to open or close the door without operating the alarm. In Figs. l, 2 and 3, 16 indicates IOC a casing in which there is a pivoted lever 17 having at its rear edge a segment gear 18 in mesh with a pinion 19. The pinion is adapted to be turned from the inside by a knob 2O and from the outside by a key. The forward end of the lever 17 has a projection 21 and when the rear end is depressed by the pinion, the forward end rises to the level of the shoulders 14, 15 and supports the trigger 3 while it is being carried over the side opening2 in opening or closing the door. As used upon doors, the outer end of the trigger is rounded and as the door closes, the rounded end strikes upon a cam surface 22 in the casing 16 and is guided into the casing and remains within said casing until the door again opens, the cam 22 projecting sufficiently to carry the trigger across the opening and onto the shoulder 14 when-the door is closed.
A spiral spring 23 holds the rest 21 normally down as shown in Fig. 1, and it may be locked in this position when desired by a sliding catch 24. It is desirable to do this at night to prevent unauthorized persons from entering with a key.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
1. In an alarm fastening forwindows or doors, the combination with the hollow casing having a side opening 2 at the end thereof, a transverse abutment or partition at the base of the opening, and a loose plate 9 separated from the abutment by a compartment 8 of a plunger within the casing and passing through said abutment and plate, an arm upon one end of the plunger constructed to rest against the end of the casing and to pass into the side opening when brought opposite thereto, a head upon the opposite end of the plunger and a spring confined between said head and the transverse partition or abutment, substantially as described.
2. The combination with an alarm fastening for attachment to a door casing having a spring pressed plunger and trigger and a support for a cap, of a casing for attachment to the door, a pivoted lever within the casing having a support 21 for the trigger at one end and a segment gear at the opposite end, a pinion in mesh with the gear and means for turning the pinion to support the rest, substantially as described.
3. The support for attachment to a door consisting ot' a casing 16, a lever pivoted in the casing having a rest 2l at its forward end, and a segment gear at its rear end, a pinion in mesh with the gear, means for operating the pinion a spring for holding said rest in its lowest position, and a sliding catch for locking it in said position, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
JOSEPH F. GRAYBILL.
