N. o. HoLMsTEN wmoow Loox Filed April 23' 1949 JNVENTOR.

Patented Oct. 14, 1952 UNITED NSTATI-:s PATENT OFFICE 1 Claim.

ly This invention relates generally tof window latches, and more specifically to window latches .having `incorporated therewith locking means 4which prevent the latch fromV being released by unauthorized persons.

An object of the invention is to provide a lockf fing means for window latches which is very effective in operation and is of simple construction and relatively inexpensive to manufacture.

Another object of the invention is toprovide a locking means for window latches which may be quickly and easily applied to window latches already in use.

Still another object of the invention is to provide an improved window latch which has incorporated therein a locking mechanism by which the latch is locked in latching position.

Other and more limited objects of the invention will be apparent from the following specication and the accompanying drawings forming a part thereof wherein:

Fig. 1 is a sectional plan view through the upper sash of a two-sash window showing a locking mechanism constructed according to my invention applied thereto with the parts in locking position;

Fig. 2 is a vertical section taken on the line 2 2 0f Fig. 1;

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2 showing the various parts in locking position;

Fig. 4 is a View similar to Fig. 3 showing the parts in unlocked position; and

Fig. 5 is a vertical section taken on the line 5 5 of Fig. l.

My invention as disclosed herein is adapted to be applied to Windows having upper and lower sashes which are slidably mounted in suitable frames for vertical adjustment. This type of window is usually provided with a latching mechanism which is mounted on the inner side of the sash frame in order to prevent the window from being opened from the outside. But this type of latching mechanism can be released by unauthorized persons if the window pane is broken or a small section cut out thereof to afford access to the latch from the outside, unless some positive locking means is provided to prevent release thereof by unauthorized persons. With my invention such unauthorized release of the latching mechanism is prevented even though a person has established access thereto.

Referring now to the drawings by reference characters, the numeral lY indicates the upper sash of a window and the numeral 2 indicates thelower sash thereof, both of 'which are slidably mounted for-vertical adjustment in a suitable iframe. 1 The Suppersash I .frame member 3.and a glass Vpane 4, Yandvthe .framemember ZIincludes a .top frame member includes a Lbottom Stand aglass pane 6. When thewindow is .closed thezframe members 3 and 5 engage. each otherV as indicated at 1.

In accordance with the invention I provide a combined locking and latching mechanism generally indicated by the numeral 40 which comprises a keeper 4l and a locking cam 42. The keeper 4| comprises a base 43 and an upwardly and inwardly extending hook 44 formed integrally therewith. The base 43 is secured to the bottom frame member 3 of the upper sash I by screws Ma. The locking cam 42 is pinned to a shaft 45 which is rotatably mounted in a casing 46 which is secured to the top frame member 5 of the lower sash 2 by attaching screws 4T. The casing 46 consists of a base 48, a top 49 and a rectangular frame 59 disposed between the top 49 and the base 48. The base 48, top 49 and frame 59 are all secured together by Suitable screws or bolts 5I. The cam 42 when in lock position, as shown in Figs. l, 3 and 5, extends out through an opening 52 in one side of the frame and engages beneath the hooked end 44 of the keeper 4I. The shaft 45 is rotatably supported in a suitable bearing 56 in the top 49 with a lower reduced end 54 suitably journalled in an aperture 55 in the base 48. The upper end of shaft 45 extends out through the top plate 49 and has pinned thereto an operating lever 51 by which the shaft 45 is adapted to be turned to move the cam 42 back and forth between the locked position shown in Fig. 3 and the unlocked position shown in Fig. 4. A bushing 53 holds thev shaftV 45 and cam 42 in place. A stop 58, by which the movement of the cam 42 is limited in either direction, extends upwardly from the base plate 48 within the casing 46.

In order to lock the cam 42 in latching position, I provide a locking arm 60, the free end BI of which is adapted to be moved into and out of the path of movement of a shoulder 42a of the cam 42, as shown in Figs. 3 and 4. The locking arm is secured to the rotating plug 62 of a Yale cylinder lock 63 which is suitably mounted in an aperture 64 in the front wall of the casing 46. The locking arm 60 is adapted to be locked in the path of movement of the shoulder 42a of the cam 42, by the locking mechanism 63 in order to prevent the rotation of the cam 42 to withdraw it from the keeper 4I and release the latching mechanism. From this it will be seen that it will be impossible to release the latching mechanism unless the lock 63 is unlocked and the locking arm 6I moved out of the path of the cam 42. A

From the foregoing it Will be seen that I have provided a very simple and efcient mechanism for accomplishing the objects of my invention.

It is to be understood that I am not restricted to the specific forms shown and described herein, as various modifications may be made thereto within the spirit of the invention.

What is claimed is:

In a latching mechanism for a window having a pair of slidable sashes with engaging frame members and a keeper secured to one frame member, a casing to be secured to the other frame member, said casing having closed top, bottom, front and end walls and a rear Wall with an opening, a vertical shaft rotatably mounted in said housing and extending upwardly through said top wall, a handle on said shaft above said top wall for turning said shaft, an arcuate latching cam mounted on said shaft Within said casing to extend through said opening and having an arcuate cam surface to engage beneath said keeper for latching said window, said arcuate cam having a substantially radial end forming a REFERENCES CITED l The following references are of record in the file of this patent:
