COMBINED BURGLAR-ALARM AND SASH-LOCK.
SPECIFICATION forming part of Letters Patent No. 391,881, dated Gotober S9,. 1888.
(No model.)
To (LZZ whom, it may concern.-
Be it known that I, ARCHIE B. OAUDLE, of Monroe,in the county of Union and State of North Carolina, have invented anew and Improved Automatic Burglar-Alarrn and Sash- Lock, of which the following is a full, clear, and exact description.
This invention relates to a device for locking a window-sash, which also serves, when an attempt is made to raise the window, to give an alarm to the inmates of the house.
The invention has for its object to provide a simple and effective device for this purpose, constructed and arranged as hereinafter de scribed and claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 represents a portion of a windowsash and frame, showing the device in position. Fig. 2is a detail View of the alarm mechanism, and Fig. 3 is a sectional detail view of the locking device. 7
In the construction of this invention the window-sash is provided with a catch, which engages a projection secured to and adapted to slide upon the window-frame, and having connected therewith an automatic device for operating an alarm.
'In carrying out my invention a plate, 1, of metal or other suitable material, is fastened to a window-frame, 2, by means of screws 3, or in any other suitable way. The plate 1 is formed with a slot, 4, having beveled sides 5, with which a correspondiugly-shaped rib or tongue, 6, secured to a sliding block, 7, by screws 38, engages. The rib or tongue 6 equals in length a portion of the slot 4, so as to permit the block 7 to be moved a limited distance on the plate 1. The block 7 is provided at one side with a slot, 8. which is protected by a slotted plate, 9, fastened to the block 7.
At the upper end of the slot 8 is located the end of a wire, 10, with which the shoulder 11 of a-curved catch, 12, pivoted to the plate 9, is in contact. The curved ends 13 14 of the catch 12 are acted upon by an arm, 15, fastened to the plate 1, having its end 16 bent over the plate 9 in the line of movement of the arms 13 14 of the catch 12. The wire is pivoted to a stud, 17, on the plate 1 by being bent around the same, and has at its upper end a hammer, 18, which is adapted to strike against the hell 19, mounted on the plate 1.
It will be seen that the wire 10 is bent to form a bell-crank lever consisting of arms 20 21, the arm 20 having connected thereto a re tractingspring, 22, fastened at its other end to a stud, 23, on the plate 1. Thelatter is hollowed out, as at 24, to permit of the movement of the connection of the spring 22 with the arm 20. A stud or pin, 25, on the plate 1 limits the action of the spring 22 on the arm 20.
Upon the block 7 are pivoted two curved arms, 26, having their pivoted ends formed with racks 27, whereby they operate in unison. The pivoted arms 26 are adapted to be thrown toward each other by means of a spring, 28, fastened to the block 7, and are limited in their movement by means of a stop, 32, on the block 7. The ends of the curved arms 26 engage a catch, 29, consisting ofa strip of metal having bent ends 30, secured to a windowsash, 31. The curved arms 26 are thrown into engagement with the bent ends of the catch 29 by means of the spring 28.
The operation of my device is as follows: The curved arms 26 being in engagement with the bent ends 30 of the catch 29, if an attempt is made to raise the sash 31, the catch 29 and arms 26, engaging therewith, will move with the window-sash and carry the block 7 upward until the upper end of the rib 6, sliding in the groove 4, strikes the upper end of the groove 4. The block 7, sliding upward, carries with it the catch 12, having its shoulder l1 engaging the wire 10, and the latter is raised until the block 7 has reached the limit of its upward movement, when the curved portion 14 of the catch 12, having moved under the'bentend 16 of the arm 15, finally releases the shoulder 11 from the wire 10, and the spring 22 thereupon "throws the hammer 18 against the bell19 to sound the alarm. Upon sliding the block 7 down again to its normal position the end 13 of the catch 12 is brought under the bent end 16 of the arm 15 to throw the shoulder 11 again into engagement with the wire 10.
By means of the construction heretofore de-= scribed it will be seen that the device not only serves to give an alarm when the sash is partly raised, but also acts as a lock. If ventilation is desired, the sash may be raiseda little way without tripping the alarm mechanism. The windowsash may also be raised entirely up by throwing the arms 26 out of engagement with the catch 29. The upper sash may be fastened in any suitable way, or the device herein described may be attached thereto with tripping mechanism reversed.
While I have described a specific construction of parts, I do not intend to limit myself thereto, as I regard my invention as covering any construction whereby a catch on the sash will serve in connection with a sliding projection on the window-frame and an alarmtripping mechanism to act as a lock and an automatic alarm.
The advantages of my device are that it is simple in construction and easily operated, it provides a lock for the sash which operates the alarm, the sash may be partly raised for ventilation, there is no danger ofits getting out of order, and the alarm may automatically reset itself.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In aburglar-alarm, the eombination,with the attachingplate, the alarm, and its operating or sounding arm or lever, of a movable block on the attaching-plate, a catch carried by said block and engaging said arm or lever when retracted, and a relativelystationary tripping projection or arm in the path of the said catch to move it and release the alarmoperating arm or lever after it has been projected or thrown by said block and catch, substantially as set forth.
2. In a bu rglar-alarm, the combination,with the attaching-plate, the alarm, and the spring actuated arm or lever for operating or sounding the same, of a block movable upon the attachingplate and provided with a pivoted catch engaging said spring-operated arm or leverto move it against theaction of its spring, and a stationary tripping projection or arm in the path of the said catch to throw the same and release said pivoted arm or lever, and a stop limiting the return movement of the arm or lever, substantially as set forth.
3. Thecombination,withtheattaching-plate and the alarm sounding or operating arm or lever, of the vertically-movable bloek,a catch pivoted between its ends to the block and having its ends projecting outward, the inner face of the catch having a shoulder to engage the arm or lever in its normal position and project it against the action of the spring when the block is moved, and a projection or arm se cured to the attaching-plate and extending transversely across the said pivoted bodilymova-ble catch between its ends and in the paths thereof, whereby when the block moves the catch in one direction one end of the catch will strike the said projection and throw the shouldered end outward, and when moved in the opposite direction the other end of the catch will bestruck and its notched end thrown to again engage the alarm operating or sounding arm or lever, substantially as set forth.
4. The combination, in a burglar-alarm for windows, with an alarm having an operating or sounding arm or lever, anda movable block for operating said arm or lever, of a sash-fastener secured to the block to engage a sash and operate the block when a sash is opened, sub-' for operating said arm or lever, of two oppositely-i nclined sash-fastener arms pivoted upon said block and connected at their inner ends for simultaneous movement, substantially as set forth.
6. In a burglar-alarm for windows, the combination,with the alarm having aspring-actuated operating lever or arm,of the sliding block having a catch pivoted upon it to move independently and to engage the said lever or arm and project it against the action of its spring, a stationary projection or arm projecting across the said catch in the paths ofthe ends to throw it into and out of engagement with the alarm sounding or operating arm or lever, and the two sash-fastening arms secured to the block to engage the sash at higher and lower points, whereby when the sash is opened the alarm operating or soundinglever will be projected and released, and when the movement of the sash ,is reversed the catch will be thrown into engagement with said lever or arm, substantially as set forth.
