4 Claims. (01. 116-16) This invention relates to devices used for protecting against unauthorized opening of closures, such as windows.

One of the objects of this invention is to provide a device that will automatically brace itself against any opening movement though yielding to closing movements.

Another object is to provide a device that will sound an alarm upon being acted upon in a closing direction.

Another object is to provide a device that may be reversed for pressing or pulling aotuations.

Another object is to provide a device that will maintain itself in operative position by means of a spring-actuated cam.

Another object is to provide a device of this type that may be held by a cam in inoperative position.

Other objects will appear from the following description as Well as from the appended claims and the accompanying drawing, in which Fig. l is a side elevation of a device designed to operate according to this invention as applied to windows.

Fig. 2 is a fragmentary top plan View of the I alarm-bell partly broken away to show inside parts cooperating with parts of the window-lock.

Fig. 3 is a fragmentary sectional View of parts of the window-lock as seen on line 3-3 of Fig. 2.

Fig. 4 is a cross section through the yielding sliding members of the window-lock without any other parts as seen on line 4-4 of Fig. 2.

Fig. 5 is a cross section on line 55 of Fig. 3 disregarding any other but the sliding parts.

Fig. 6 is a top plan View of the spring for the sliding parts.

Fig. '7 is a fragmentary schematical view of the position in which the hinge parts may be set for inoperative position.

Fig. 8 is a fragmentary, somewhat schematical illustration of the cam. parts and their operations.

It is very desirable, to have windows open, not only during the day, but-also during the night against risks of burglars.

Some people prefer vertically shiftable windows partly opened at the top as well as near the bottom, requiring safety means eventually for two sashes. Setting a window so that the upper sash is partly down and the lower sash is partly up is supposed to give a better ventilation and circulation of the lower opening to bring .in fresh air, while the upper opening is to bring air from the room to escape through this opening.

The present invention is designed and constructed so that both sashes may be controlled at the same time by one and the same device, with an assurance that an alarm will be sounded additionally to a normal locking of the sashes against attempts of opening.

The bell-part of this device may be of a form to be had on the. open market and of a general outline as indicated at I l in Figs. 1 and 2. Such a type of bell is commonly provided with a bellhammer attached to some sort of arm l2, controlled by some sort of escapement I3, as indicated in Fig. 2 under the broken-away bell-top. Such a bell may be wound for operation,'to be held inoperative by merely preventing the escapement and bell-hammer from operating, as by a stop such as indicated at M in Figs. 2, 3, and 5.

In the present case, this stop It is made as a part of the yielding bell-controlling slide-part E5 of the brace I 6, the stop I4 being made to move for a limited extent in a slot ll of the brace, the stop extending upwardly into the bell that is attached to the top of the brace.

The stop It is normally held pressed against the bell-mechanism automatically by a spring 18 that is inserted between the slide-part l5 and the brace I 6.

In order to provide for a suitable space in which the spring may operate properly, the edges IQ of ing means of the slide-part within the structure of the brace. The edges of the brace are also bent, or provided with lugs 20, extending over the slide-part so as to slidably hold the slide-part within the brace for movements limited by the slot ll with respect to the stop l4.

Such movements could easily be made controllable in both opposite directions by the slot; however, inasmuch as the bracing may have to be rather strong, the whole brace-structure is designed. so that the inner end 25 of the slidemember 55 can abut against the hinge-lugs of the brace, as at 22 in Fig. 3.

In other words, though the slide-part I5 makes the brace yielding, the brace is nevertheless suitably rigid when compressed beyond the yielding point. In such rigid condition, the brace may be expected to firmly act against any contrary movements of any parts against which this bracing effect is used.

In Fig. 1, for instance, the bell-supporting brace is in position braced against a portion 23 of an upper sash of a Window; while the brace is supported by a clamp-mounting 2 8, which is clamped to the upper portion 25 of the lower sash of the same window, the clamp-mounting having a hook-portion 26 to engage over one side of the sash while a set-screw 21 engages over the pposite side, thereby firmly holding the clampmounting to the sash.

The brace, however, is hingedly connected to the clamp-mounting 24 at 28, and the whole brace with the supported bell may be swung to the position indicated at 16a with respect to the c1ampmounting indicated at 24a in Fig. 7. In this inoperative position it will be held by a certain cam arrangement.

In Fig. 8, the brace-portion "is is for this purpose shown with one plain knuckle 29 and one cam-knuckle 30; and the clamp-mounting-portion 2% is shown with 3| that is plain at one end, or edge 3 is and a cam-end, or edge 3 lb.

The cam-knuckle 30 is designed to co-operate with the cam-end tit, the cam-knuckle 30 of the brace-portion "it having one deeper notch 30s and a shallower notch 3%. One side-edge of the deeper notch 30a and one side edge of the cam-end 32b is suitably slanting to act as a returning means for limited movements of the brace with respect to the clamp-mounting while in bracing position so that any attempt of lifting the brace through the split between the two window-sashes will be counteracted by this returning cam-action.

The owner of the house, particularly, any person at the inside of the house, however, may get the brace beyond this returning cam-action until the cam-end 31b comes to rest in the shallower notch 3%, which is equivalent to the position indicated at '63. in Fig. 7.

A plain compression spring 32 on the pintle 33 is inserted between the plain knuckle 29 and the plain edge 3's. so as to keep the cams under the tension of this spring.

From the above it should be clear that, with the brace and sashes in the positions shown in Fig. 1, any movement of either of the sashes is limited to such an immaterial extent as to make any unwarranted or unauthorized attempt towards opening the Window practically impossible.

While the slide-part 15 has mainly been described as-working against pressure, which is the most desirable when applied to the type of windows referred to, it should be understood that the slide-part may just as easily act against pulling, it merely requiring a slightly different mounting of the bell on the brace so that the bell-hammer and escapement comes to be located along the opposite side 34, in which case a releasing of the escapement would be in the direction of the arrow 36 instead of in the direction of the tarrow 35 in which it happens to operate on the side on which the operating mechanism have been illustrated, it merely necessitating a changing of the stop M to the opposite side of the slide-part 95, a very insignificant mere mechanical expedient that any mechanic can produce without further showing.
