Application October 13, 1945, Serial No. 622,214

The present invention relates to window locks and, more particularly, to looks for windows of the sash frame type.

- It is an object of the present invention to provide window locks of the character described which are at all times completely detached from the window and sash frames and may be transferred for use from window to window, as may be required.

It is another object of the present invention to provide window locks of the character described which may lock both upper and lower sash frames, simultaneously, and which may lock them in closed or partly open position.

It is also an object of the present invention to provide window locks of the character described which are efficient and completely safe against breaking open and the effectiveness of which may increase with any effort to dislodge them.

It is a further object of the present invention to provide window locks of the character described which are of rugged and sturdy construction and highly effective for their purposes even after repeated use.

It is a still further object of the present invention to provide window locks of the character described which are of simple construction, which are economical to produce and which are simple and easy to use and manipulate.

The foregoing and other advantages and superiorities of the window locks of the present invention will become more apparent from the embodiments thereof shown in the accompanying drawings and from the description following.

It is to be understood, however, that such embodiments are shown by way of illustration only,

2 Claims. (Cl. 292343) to make the principles and practice of the invention more readily comprehensible, and are not presented with ny intention of limiting the present invention to their specific details.

In the drawings:

Fig. 1 is a view in side elevation of one embodiment of a window lock of the present invention, shown in position between an upper and a lower sash frame, and partly in vertical section to show details of construction and operation;

Fig. 2 is a View in front elevation of the window lock of Fig. l, similarly shown in position between an upper and a lower sash frame;

Fig. 3 is a view similar to Fig. 1, showing a modified embodiment of the window lock;

Fig. 4 is a view in front elevation of the Window lock shown in Fig. 3;

Fig. 5 is a view in side elevation and partly in section of another embodiment of a window lock of the present invention, showing the same in operative position;

Fig. 6 is a view taken on line 66 of Fig. 5;

Fig. 7 is a top plan view of the window lock shown in Fig. 5; and

Fig. 8 is a front elevation of the same.

Referring more specifically to the accompanying drawings, the lock of Figs. 1 and 2 com prises a pair of elongated, rigid plates, as of steel or the like, consisting of an inner plate, It, and. an outer plate, II, which are connected together by a thumb screw, [2, or a similar device.

The inner plate Ill may be provided, intermediate its ends, with a boss, !3, through which and through the plate may be provided a threaded opening, 14, for receiving and engaging the screw, l2.

The outer plate, Il, may be provided with a boss, l5, through which is formed an opening, it, which receives the reduced end, ll, of the screw l2, which end is, swaged, as at !8, to rotatablyretain plate I l on the screw l2.

In operation, plates Ill and II may be brought close together by turning screw l2 in the proper direction and their ends below the boss l3 inserted into the space intermediate the upper and lower sash frames, l9 and 20, and the screw I2 may then be turned'in the opposite direction, to space the plates It and l I, forcing them against the sash frames which they respectively contact, thus jamming such sash frames against the window frame and effectively locking them in place. When the window is completely closed, the lock may be inserted along any portion of the horizontal sides of the sash frames 23 and l 9;

however, when either of such sash frames is in open position, the lock must be inserted between the vertical sides of the sash frames l9 and 2t.

In order to prevent relative rotation of the plates l0 and II during the initial locking operation, before sufiicient friction is developed to hold them against the frame sides, a pair of lugs 2| may be provided along the edges of one of the plates, as H, which are adapted to engage the side edges of the other plate, to prevent their relative rotation.

In the modified embodiment of Figs. 3 and 4, the plates l0 and H are connected at their upper edges by an arcuate sprin portion 25, preferably integrally formed, which is shaped to normally press the lower ends of said plates together and which acts to increase the space between them downwardly when screw [2 is turned to push them apart, whereby any effort'to dislodge the device after it is locked in position will tend to jam it more tightly in position and to lock the sash frames more effectively in place.

Since in the embodiment of Figs. 3 and 4, the plates I and II are connected at one end, lugs 2| may be eliminated. Likewise, plate U need not be engaged upon the end of the screw l2, but such end may abut against plate II, to push against it when the screw I2 is turned in locking direction.

If desired, the lower portion 26 of plate l0, may be slightly inwardly bent, to conform to the generally downwardly and inwardly sloping rear surface of the upper horizontal frame member of the lower sash frame, and the end 21 of such plate, may be rearwardly offset in a mannor to engage the underside of such frame side.

In the embodiments of Figs. -8, the lock comprises a plate 30 set on edge and having an end 3| offset at right angles thereto, and at the other end, extending sideways, in a direction opposite to the end 3|, a stud 32. The stud 32 is provided with a threaded openin 33, which receives and engages the thumb screw 34.

On the end of the screw 34 is mounted for free rotation a second plate 35, as by means of the boss 36, formed in such plate and provided with the opening 3'! fitting about the reduced end 38 of .the screw 34, whose swaged end 39 retains the plate 35 in position. The plate 35 may be provided with a rearwardly offset end portion, 40.

In operation, the embodiment of Figs. 5-8 may have the offset end 3| of plate 36 inserted between the upright member 4| of the upper sash frame and the upright of the window frame 42, the sash frame being first lowered slightly to facilitate insertion. The lock is then slid down along the sash'frame l9 until the stud 32 is directly above the lower sash frame 20. The thumb screw 34 is then turned in the direction to have the plate 35 bear and press against the spacing bar 43 generally provided in window frame between the upper and lower sash frames 9 and 20, respectively.

It will be apparent that additional turning of screw 34' will cause plate 35 to push against the bar 43, and plate 30, by its end 3|, to pull the frame away from the window frame 42, to jam it against the opposite side of the window frame and thus lock the sash frame I 9 in position,

To lock the lower sash frame in position, either or both the stud 32 or the member 40 may be made somewhat wider than the bar 43, so that a portion of such stud or member will overhang the upright member of the lower sash frame to prevent the latterfrom being moved upwardly.

It will be readily seen from the illustrative embodiment of the drawings that the lock of Figs, 5-8 may be readily used with any of the con-. ventional type of sash windows, including those provided with weather stripping, such as 44, or with the ropes 46.

It will also be readily apparent from the foregoing that the locking devices of the present invention are of relatively simple and economical construction, that they are easy and simple to use, that they do not require attachment to any part of the window or its frame and may therefore be transferred from one window to another as occasion may require, and that they are highly efficient and effective for their purposes.

What I claim is:

1. A window lock of the character described comprising a pair of ubstantially parallel plates having free end portions adapted to be inserted intermediate upper and lower window sashes, one of said plates haying a threaded opening formed therein, a thumb screw vengaged'in said opening, the second of said'plajtes being freely and fixedly mounted on the inner end of said thumb screw, whereby the space between said plates may be adjusted and means on one of said plates for engagin the edges of the other of said plates to limit the rotation of the plates relative one another aszthe said thumb screw is turned.

2. A window lock of the character described, comprising a pair of substantially parallel plates having free end portions adapted tov be inserted. intermediate an upper and lower 'window sash, one of said plates having an internally boss formed thereon, a. thumb'screw engaged in the said boss, the second of said plates being freely and fixedly mounted on the inner end of said thumb screw, whereby the space between said plate ends may be adjusted, and lugs on the side edges of said second plate adapted to engage against the edges of said first plate to limit the rotation of the plates relative to one another.
