UNITED STATES PATENT OFFICE.

WILLIAM .E. HALLETT AND FRANK KAMERER, OF NEW YORK, N. Y.

ELECTRIC SIGNALING.

To all whom it may concern:

Be it known that we, WILLIAM E. HAL- LETT and FRANK KAMERER, citizens of the United States, and residents of New York, counties of Kings and Queens, respectively, State of New York, have invented certain new and useful Improvements in Electric Signaling, of which the following is a full, clear, and exact description.

This invention relates more particularly to burglar alarms.

The primary object of the invention is to provide sim le and efficient means whereby an electric ell or other alarm arranged at any suitable point may be made to ring as soon as a window or other object is moved, and which when once set to close the circuit through the electric bell the latter will con tinue to ring until the circuit is again opened by manually releasing the locking means.

A further object of the invention is to provide a device adapted for use in various connections; which when once set is ositively locked and held so as to cause t e bell to continue to ring and at the same time positively holds the window or other object from further movement, and which is so arranged that it is not readily accessible to permit being tampered with from without the object in connection with which it is used to stop the ringing of the bell or other alarm.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this s ecification, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is an elevation, partly in section and partly diagrammatic, of one form of device embodying our invention. Fig. 2 is a vertical section on a larger scale,

artly in elevation, taken on the line 22 of Fig. 3. Fig. 3 is a vertical section through the locking device and circuit closer taken on the line 3-3 of Fig. 2. Fig. 4 is a sectional plan, partly in elevation taken on the line 44 of Fig. 2; and Fig. 5 is a sectional plan showing the invention as applied to a swing ing member as a door window, transom and the like. 154 (2,.

The window frame 0 may have the sliding sash 11 and may be constructed and operated in the usual manner. As shown the window is vertically movable, and adjacent to its inner edge is a device 12. This device 12 has a hollow shank 13 and on the end of Specification of Letters Patent.

Application filed May 29, 1907. Serial No. 376,355-

Patented May 26, 1908.

the shank 13 is a button or looking part 14, which is adapted to enter a recess or opening 15 in the window sashwhen the window is raised a sufficient distance to cause the recess or opening to register with the part 14. This recess may have a metal bracket 16 fitting therein so as to take the strain 0H the wood of the window sash, and said recess is preferably located, so that the device 12 will enter the same when the window has been raised a short distance but not suflicient for any one to enter through the window. The normal position of the device 12 is that shown in Fig. 4 in which position the device 12 is normally held by the window sash, the end 14 being rounded and of such a shape that the movement of the window will not be interfered with when raised or lowered, unless otherwise prevented as will be presently described. A rod 17 has one end entering an opening in the device 12 to serve as a guide for the latter at one end thereof,

and the other end of said rod is secured to a bracket 18, the ends of which are fastened to the window frame, and around the rod 17 is a spring 19 which normally forces the device 12 inward to cause the end 14 to enter the recess 15 when the latter is brought to register therewith.

For the purpose of holding the device 12 against outward movement after the end 14 is in looking engagement with the window sash, we provide a latch retaining device or bolt 20. This device 20 is slidingly held in a bracket 21 secured to the window frame, and the inner end of said retaining device 20 is beveled, as at 22, and normally engages the end of a collar or flange 23 on the outer end of the device 12 when the said device is in an unlocked position as shown in Fig. 4. The retaining device 20 is cut away or recessed, as at 24, to span the rod 17 and spring 19 when forced inward, and has a rod 25 on which is a collar 26. A spring 27 is arranged around the rod 25 and is located between the window frame and the collar 26, so that immediately the window is raised andthe recessed part 15 registers with the end 14 of the device 12, the spring 19 will force said device 12 inward to enter the recess 15, and in this position the spring 27 will act upon the retaining device or bolt 20, so as to force the same inward past the collar 23 of the device 12, and will positively hold the same inward until the device 20 is again released. By this means the window will be positively held against movement and cannot be raised or lowered, as the retaining device 20 will prevent outward movement of the device 12 by engaging the outer face of the flange 23 as shown in Figs. 2 and 3, and until the device 20 is withdrawn to release the device 12, at which time the device 20 may be made to engage the flange 23, which will hold the same outward against the tension of the spring 27. To secure this releasing movement of the retaining device 20, the rod 25is provided with a handle or knob 28 on the outer end of said rod, and said handle is usually arranged convenient to the Window within the room. A plate 29 having a recess 29 is secured to the window frame, and the end of the rod 25 is screw-threaded, so that the knob or handle 28 may be removed therefrom at night or at ony other time, thereby making it impossible to tamer with the retaining device 20 to release it from the locking device 12 from without the room. By screwing the handle 28 on the rod 25, the retaining device 20 may be forced and held in the position shown in Fig. 4.

To sound an alarm, we make the flange 23 of the device 12 form a part of an electric circuit, and against the window frame and within the path of movement of said collar or flange 23 are the

contacts

30 and 31. These contacts are included in an electric circuit 32, and this circuit includes an electric bell or other alarm 33, a battery 34 and a switch 35, the latter being intended to break the circuit during the day time, or at such other time as is not desired to ring the alarm, the said switch being located at any convenient point. As will be seen when the window is slightly raised as shown in Figs. 1, 2 and 3, so that the end of the device 12 will enter the recess 15 in the window sash, the circuit will be completed by the collar 23 engaging the

contacts

30 and 31, and will complete the circuit through the electric bell 33, battery 34, and switch 35, the said circuit being open when the device 12 is in the position shown in Fig. 4, or when the switch 35 is thrown to the position indicated by dotted lines 36, Fig. 1 to open the circuit.

In Fig. 5 the part or member 37, instead of sliding as in the other figures is pivoted at 38 to the frame 39, so that as soon as the said part 37, whether a door, transom or window is swung on its pivot or hinge, the device 12 will close the electric circuit and ring the alarm in substantially the same manner as already described.

From the foregoing it will be seen that simple and efficient means are provided whereby a window or other object when tampered with will cause an electric bell or other alarm to be sounded; that a simple alarm is provided which may be readily applied to various forms of windows and the Having thus described our invention, we

claim as new and desire to secure by Letters Patent 1.
