Application May 7, 1934, Serial No. 724,322

4 Claims.

This invention relates to new and useful improvements in an adjustable lock for windows.

The invention has for an object the construction of a look as mentioned which is adapted to be attached upon the top of an inner window sash and is provided with clamping screws engageable against the outer window sash and against the frame of the window for the purpose of holding the sashes locked to each other and locked to the frame.

More particularly the invention relates to the construction of certain brackets adapted to hold the screws in operative positions.

Still further the invention contemplates constructing the brackets mentioned in the previous paragraph of substantially U-shape with the screw engaging through both of the arms of the U-shape, and the U-shape brackets being attached upon the body of the lock at their center portions, that is, the bends.

Still further the invention also contemplates the association of strips with apertures for receiving the ends of the screws, arranged upon the outer sash and upon the frame for coaction with the screws.

Still further the invention alSO proposes the provision of means whereby the U-shaped brackets forv holding the screws are adjustably mounted upon the body of the device and arranged in a manner so that they may be locked immovable in operative positions, and upon slight turning of .the screw be movable into inoperative positions and so prevent the necessity of an exceedingly large number of turns upon the screws to disengage the screws from the strips.

Still further the invention proposes the construction of a device as mentioned which is simple and durable and which may be manufactured and sold at. a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a fragmentary elevational view of a portion of a window frame with inner and outer sashes and provided with an adjustable lock according to this invention.

Fig. 2 is a fragmentary sectional view taken on the line 2-2 of Fig. 1.

:Fig. 3 is a perspective view of Fig. 1.

Fig. 4 is a fragmentary elevational view of Fig. 1 but illustrating another embodiment of this invention.

Fig. 5 is a sectional view of the lock per se taken on the line 5--5 of Fig. 4.

Fig. 6 is a sectional view taken on the line 66 of Fig. 5. v

The adjustable lock for windowsaccording to this invention comprises an inverted L-shaped body having a top horizontal arm HI and a vertical bottom arm II, and is attached upon the top edge of an inner window sash 12. More particularly the corner of the L-shaped body is engaged against the corner of the top edge of the sash and arranged so that a top arm l0 extends over the top of the sash while the vertical arm ll extends down along the front side. Screws l3 are engaged through the arms of the L-shaped body and into the frame portion of the sash for the attachment of the body in position. U-shaped brackets l4. and are attached upon their central portions .uponthe arms of said body, and are arranged so as to adjustably hold screws l6 and Iladapted to be engaged respectively with strips l8 and I9.

The window sash I2 is mounted in a conventional window frame 20, not illustrated in detail upon the drawing and which is associated with an outer sash 2|. A strip I8 is attached .upon the outer sash 2| and is formed witha plurality of openings 22 adapted toreceive the end of the screw Hi. The screw 16 isthreadedly-engaged through both of the arms of the bracket 14 and the bracket is attached at the central portion, that is, the bent portion upon the top of the body. More specifically the bracket I4 is arranged to be endwise of the plane of the sash 2|. I p

The bracket I5 is attached upon the vertical arm ll of the body and is arranged endwise to the side of the frame 20. The .strip I9 is attached upon the frame 20 and is formed with a plurality of apertures 23 adapted to receive the end of the screw I1. The screw ll threadedly engages through, both of the arms of the bracket 15, and the bracket is attached at its center upon the vertical arm ll of the body. Preferably, as illustrated in Fig. 3 the strip 18 may be much longer than the strip 19 since in practice it will be found that it is desirable to relatively adjust the inner and outer sashes through larger distances while it is desirable to be capable of adjusting the sashes in .a fixed position, through smaller distances in the frame.

In Figs. 4 and 5 a modification of the invention has been disclosed in which an arrangement is provided whereby the brackets vHand I5 are adjustably mounted upon the arms of the body and arranged in such a fashion that they may be latched in fixed positions, or upon certain operation, may be moved into operative positions. More particularly each of the brackets is formed with a bayonet slot 25, of substantially L-shape, upon the central portion of the bracket, and these slots are engaged by rivets 26 pro- The shanks of the rivets 26 are square, as illustrated in Fig. 5, so that when engaged in the recesses 25 the brackets cannot rotate.

The recesses 25 are comparatively shallow, substantially one-half of the thickness of the shanks of the rivets and the arrangement is such that the depth of the recesses 25' is much smaller than the thickness of the strips 58 or E9. This arrangement is such that normally, when the screws I6 and I! are screwed in completely into the openings of the strips, and the window is held in the latched position, the brackets 54 and l 5 will be urged outwards so that-the recesses 25 engage the shanks of the rivets 26 and so the brackets are held in fixed position against rotation.

If it is desired to unlatch the windows the screws [6 and i! need be turned only several turns so as to be capable of moving the brackets I 4 and I5 inwards to disengage the shanks of the rivets from the recesses 25 Then the brackets'may be moved laterally so that the shanks of the rivets pass along the short arms 25 of the L-shaped slots and then longitudinally so that the shanks ofthe rivets pass along the long arms 25' of the L-shaped slots and it will readily be seen that the screws are disengaged from the openings of the holding strips. The purpose of this arrangement is to remove the annoyance of turning the screws through many revolutions before engagement and disengagement is possible.

While I have shown and described thepreferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

' Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:
