ALARM Filed Oct. 3, 1938 INVENTOR ATTORNEY.
Patented Mar. 12, 1940 ALARM Theodore J. Gauthier, Springfield, Mass. Application October 3, 1938, Serial No. 233,054' I 1 Claim.
This invention relates to improvements in an alarm and is directed more particularly to the provision of a novel alarm device which is automatically operated by the movement of a window sash or the like, or by the movement of one window sash relative to another window sash.
The principal object of my invention is the provision of a device which is sure-and positive in its operation and which is readily associated with and detachable from window sashes or the like. The arrangement is such that an alarm or signal is automaticallyoperated should an uninvited intruder such as a burglar attempt to raise or lower the window.
Another object of the invention is the provision of a device of the above character which is relatively simple and compact'in form and the parts are adaptedto be readily assembled and when assembled to be positively and securely retained in operative relation.
Still another object of the invention is to provide an improved construction which may be made more economically and with fewer operations, both in the manufacture of the parts as Well as in assembling them, than can prior devices known in the art.
Various other novel features and advantages of the invention will hereinafter be more fully referred to in connection with the accompanying drawing, wherein:
Fig, l is a side elevational view of the device of the invention shown in association with a window sash;
Fig. 2 is a plan view of the. device shown in Fig. 1;
Fig. 3 is a side elevational view of a modified form of the device of the invention association with a window sash;
Fig. d is a partial plan view of the device shown in Fig.3; and
Fig. 5 is aperspective view of a clamping member to be used in connection with the device of the invention.
shown in Referring now to the drawing in detail, the inthe member 22 is released, it moves outwardly so as to permit the operating hammer to strike the bell. j
It will be appreciated that when the member 22' is held against outward movement the bell does not ring. As will now appear, I provide a construction whereby the member 22 is normally held against outward movement but is released when the window sash with which it is associated v is either'rais'ed or lowered,'depending upon which 1 for directly securing the bell and bracket to g the top of one of the sashes. 1
If desired, however, there may be a clamping member M, such as shown in Fig. 5 which has opposite end portions adapted to be secured to the sash. The intermediatepart of the-member 25 is raised or spaced) from the sashso that the foot portion 42. ofthe bracket may be received thereunder as shown in Fig. l.
An arm member 45 is pivotally secured as at 48 to the 'bell 211 or bracket and it projects outwardlyv from the bell-along a horizontal plane." Positively secured to the outer end of the arm 46 is a yieldable engaging member 5|).
This member 5!! may take various forms but in the form shown, it is made of rubber. This member is adapted to engage the sash or winclo-W, as shown in Fig. 1,-in such a way that it will move with the window and thereby move arm 46 on its pivot 48.
. A lug 52 extends from the arm 46 and this is adapted to releasably engage the operating member'28 and hold it in a normal, non -operatingposition. When the arm 46 swings on its pivot 48, it carries lug 52 out of the position shown in Fig, 2 so that the operating member 22 is released. I I
In bells of'the spring operated type, when the operating member is held in normal position, the spring is held thereby against movement so that it is'impossible for the bell to ring. By moving the arm upwardly or downwardly and thereby releasing the opera-ting member, the spring is released and the bell rung. p
The device is so positioned with respect to the window that the member frictionally en- 55 gages a part of the window such as pane 38. As the lower sash 32 is raised or as the upper sash 34 is lowered, the engagement of memberill with the window causes movement of arm 46 from its normal position and consequent release of the operating member 22 and ringing of the bell.
A modification of this invention is shown in Figs. 3 and 4. According to this form, the signal consists of an alarm bell, indicated generally by provided with a spring actuated hammer and an operating member arranged to be urged inwardly to operate the bell-ringing mechanism.
This bell may likewise be supported by a bracket 62 having a leg part 64 on its lower end for reception in a clamp member 66 similar to the part M above described. The other end of the bracket 62 is preferably curved and an arm lll is pivoted thereto at 69.
A block 72 is attached to the outer end of the arm 1i] and a suction cup 14 is preferably threaded onto a threaded connection 16 secured to block 72. On the other end of the arm 10 is a lever part 18.
Connecting the outer part of arm 10 and the lower part of bracket 62 is a member 89. This member is slotted at 82 to receive a pin extending outwardly from bracket 62 as shown. As arm 18 swings upwardly on its pivot 69, it causes member 85) to move downwardly, the latter being guided by the pin and slot.
At a midpoint 84 of the connecting arm 80 is pivoted another lever 86. This has an engaging part 88 on other end adapted to overlie the operating member 9!] of the bell.
The operation of thisform of the device will now be explained.
The suction cup M is positively engaged with the sash or with the window pane 38 substantially as shown in Fig. 3. As the lower window sash 32 is raised, or as the upper window sash 3 5 is lowered, the arm '18 is caused to swing on its pivot ESQ whereupon the connecting arm 80 is urged downwardly as is the arm 86. This movement causes the engaging part 88 to press inwardly on the operating member 90 and ring the bell.
It is desired to point out that the parts 50 and M positively engage the window so that movement thereof promptly brings about operation of the signal. It is to be noted too that when the arm 46 has been moved from the positionshown in Fig. 2 and the member 22 has moved outwardly, the said member 22 remains out until manually pushed back in. That is to say, the intruder could not stop the ringing of the bell merely by closing the window because the lug 52 would, upon movement of the bracket toward normal position, engage the side of the operating member in extended position rather than override it and urge it to its inner position.
While I have described the invention in great detail and with respect to the present preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention. What it is desired to claim and secure by Letters Patent of the United States is:
The combination with upper and lower window sashes containing windows and movable between open and closed positions, of a burglar alarm comprising, a bell attached to the upper side of the lower sash, an operating member extending longitudinally outwardly from a side of said bell and movable outwardly relative to the bell to operate the same, a longitudinally-extending arm member having its inner end pivotally connected to a side of said bell which is adjacent said first side of the bell so as to be swingable between a normal position and a position away therefrom and its outer end in positive engagement with the windowv of the upper sash, said arm member being spaced from said operating member and disposed in a longitudinal plane parallel with the operating member, and. 2. lug member secured to said arm member so as to be movable therewith and extending perpendicularly therefrom in the direction of the operating member, said lug member being in engagement with said operating member when said arm member is in its said normal position and out of engagement therewith when said arm member is in said position away therefrom, all adapted and arranged whereby when either of said window sashes is moved to its open position, said arm member swings on its pivot away from its normal position so that said lug member is moved out of engagement with the operating member so that the latter moves outwardly to operate the bell.
