.L/LY} M927 4. 414M) United States Patent WINDOW LOCK Lily Hazy, New York, N. Y.

Application September 20, 1951, Serial No. 247,474

3 Claims. (Cl. 292-148) This invention relates to improvements in window locks, and has for an object the provision of a window lock which may be easily installed on existing windows.

Another object of the invention is the provision of a window lock wherein the attaching screws are all covered by the locking bolt when the window is locked.

A further object of the invention is the provision of a window lock wherein the bolt and a stationary part are locked together by a removable locking member which cannot be opened or forced by a burglar, even if he broke a pane of glass adjacent to said lock to gain better access thereto.

Yet another object of the invention is the provision of a window lock, of the character described, which may be utilized for locking the window in a partially open state, thereby providing both safety and ventilation for the occupant of a room in which the window is located.

Other objects and advantages of the invention will be apparent to those skilled in the art, upon a study of this specification and the accompanying drawings.

Referring to the drawings which are given by way of example to illustrate the invention:

Figure l is a perspective view showing my new and improved window lock installed on the two meeting rails of a pair of sash; V

Figure 2 is a plan view of the boltef the lock of Figure l;

Figure 3 is a side elevation of said bolt;

Figure 4'is an end elevation of said bolt;

Figure 5 is a plan view of the bolt receptacle as used on the meeting rail of the upper sash;

Figure 6 is a plan view of the cooperative bolt receptacle as used on the meeting rail of the lower sash;

Figure 7 is a sectional elevation taken along the line 7-7 of Figure 6;

Figure 8 is a sectional elevation of a form of the invention for locking the window with a predetermined opening therein;

Figure 9 is a plan view as seen along the line 99 of Figure 8;

Figure 10 is a fragmentary view showing the lower sash locked to the window frame.

Referring first to Figures 1 to 7 inclusive, my new and improved window lock is comprised of, a first bolt receptacle to be mounted on the meeting rail 21 of the upper sash, a second receptacle 22 to be mounted on the meeting rail 23 of the lower sash; and a bolt member 24.

Said first receptacle 20 is in the form of a short length of rectangular tubing, the interior passage 25 of which is open and the bolt 24 forms a working fit therein. The second receptacle 22 may also be formed of a short length of rectangular tubing or the like. The interior passage 26 with which the bolt 24 also forms a working fit is in alignment with the receptacle 20 when the window is closed. The bottom wall 27 has a tab extension 28 with a hole 29 extending therethrough, the purpose of which will be presently described. A round-end slot 31 may be 2,707,646 Patented May 3, 1955 formed in the upper wall 30 to lighten the device, however this slot does not have any eifect upon the functioning of my device.

Formed in the upper wall 30 are spaced clearance holes 32 and 33 through which the heads of the attaching screws may pass. In alignment with these holes are respectively drilled and countersunk

holes

34 and 35 to accommodate the heads of screws for securing the receptacle on the meeting rail of a lower sash.

The first receptacle 20 is provided with like holes 32a, 33a and 34a, 35a respectively, and it will be noted that when the bolt member 24 is positioned in the

receptacles

20 and 22, the screws in the

countersunk holes

34, 34a, 35 and 35a are covered by the bolt member and cannot be removed, thus providing an extra safety feature.

The bolt member 24 is comprised of a rectangular element 36 having a series of tongues 37 disposed along one edge with grooves 38 therebetween; and an element 41 having a series of tongues 39 along one edge with grooves 40 therebetween. The tongues 37 fit in the grooves 40 and the tongues 39 fit in the grooves 38 and all of the tongues have aligned holes therein through which a hinge pin 42 extends. The element 41 may be cut out to match the tab extension 28, in which case, said element is cut away on each side near the end to form a tab 43 with an elongated hole 44 formed therein.

When the bolt element 24 is positioned in the

bolt receptacles

29 and 22, after they are brought into align ment, the tab extension 28 and the tab 43 coincide so that any suitable locking means may have at least a portion thereof passing through the

holes

29 and 44.

In the embodiment shown in Figure l, I employ a padlock 45; a portion 46 of which passes through the

holes

29 and 44.

When a window lock of this nature is used, a burglar cannot remove the bolt member from the

socket members

20 and 22 even though he may have broken the glass pane 47.

Referring to Figures 8 and 9, a modification is shown wherein the portion 36 of the bolt member 24a is elongated and has a, series of tongues and slots like those shown at 37, 38 formed on the lower end thereof and engaging such tongues and slots like those shown at 39, 40, and these are formed in an element 48. Thus the 7 element 48 and the lower end of the element 36 are like- L 51 having spaced countersunk holes therein to accommodate screws 52. Secured to or formed integral with the plate member 51 is a stud 53 having a cross hole 54 therein. The stud is of such diameter that the elongated hole 440 may pass over the stud and thereafter a locking means; for example, a padlock 450: may have its U- shaped portion 46a passed through the hole 54. With this modification the length of the portion 36 may vary in accordance with how much the lower sash is to be left open at the bottom. In using this modification of the device the lower sash may be raised to a point where the portion 41 is above the stud 54 and then the bottom sash may be lowered slowly until the portion 43a passes over the stud and lies in contact with the plate 51 following which the locking means 45a may be applied.

The form shown in Figures 8 and 9 may also be used for locking the windows on the side, that is to say, through the jamb on either or both sides, in which case the element 48 is screwed onto the meeting rail 23:! of the lower sash, and the plate member 51 is screwed onto the jamb 55, and this may be done with the window closed it it is desired to lock it in a closed position or with the window partially open if it is desired to lock it in a partially open position. When it is desired to lock the window, after the lock has been installed thereon, the lower sash is moved to a position where the portion 41 may be swung over the stud 53 to a point where it engages the surface of the plate 51, whereupon the locking means 45a, or any other suitable locking means, may have a portion thereof passed through the hole 54 in the stud 53.

Although the modification described in Figure 10 is shown as applied to the lower sash, it will be understood that it may be applied to the upper sash in a similar manner. In fact it has been found very practical to apply one such lock between the lower sash and the jamb on one side, and to apply a similar lock between the upper sash and the jamb on the other side.

Although I have herein shown and described by way of example a preferred form of my new and improved window lock and a modification thereof, I do not wish to be limited by the arrangements herein shown and described, as many changes may be made in the arrangements shown and described within the scope of the following claims.

What is claimed is:

l. A window lock comprising, a pair of rectangular tubular members, said members having at least the interior passages therethrough substantially identical in crosssection, pairs of aligned holes in opposite walls of both said members and each pair comprising a countersunk screw hole and a hole to accommodate a tool for driving a screw, one of said members adapted to be mounted on the meeting rail of an upper sash and the other member being adapted to be mounted on the upper meeting rail of a lower sash, the interior passages of said members being in alignment, said second member having a lug formed integral with its lower surface and adapted to extend inwardly from said last meeting rail, and a bolt member positioned in and common to both said interior passages, said bolt member having a lug formed integral therewith matching said first lug, aligned holes formed in said lugs, and locking means extending through said aligned holes for locking said bolt member in said aligned passages, whereby said bolt member not only functions to lock said members together but it'also functions to cover the heads of mounting screws positioned in said countersunk holes.

2. The invention according to claim 1 in which said bolt member is formed of two parts hinged together one part being adapted to be positioned mostly in one of said members and the other part being adapted to be positioned mostly in the other of said members.

3. A window lock comprising, a rectangular receptacle having a hollow passage of rectangular cross-section therethrough, spaced countersunk screw holes formed in one wall of said receptacle for securing the latter to the meeting rail of an upper sash, each countersunk hole having a clearance hole in alignment therewith in the opposite wall thereof, a second receptacle having a matching passage extending therethrough and having like screw holes therein to accommodate screws for securing it to the meeting rail of a lower sash cooperating with said other sash and clearance holes in alignment therewith, said second receptacle having an extension which. overhangs said second meeting rail, a bolt member positioned in both said passages and having an overhanging portion matching said first overhanging portion, said overhanging portions having aligned holes formed therein, and locking means having at least a portion thereof extending through said aligned holes, whereby said bolt member may prevent movement of either the upper or the lower sash from being moved and also prevents the removal of the screws in said screw holes therefrom as long as said bolt member is positioned in both said passages.
