" 1 Claim. (01. rig-891' This invention relates generally to latching means for swinging windows orglass doors} More specifically, the invention relates to a locking,
means to be used in conjunction witha pivoted latch such as is used on Tcrench windows and the.
The invention is especially. designed for application to standard type pivoted latcheswhlch are already in use for holding swinging windows, and doors closed. Latches of this type are attached to the; inside of a window, or doorand,
are quiteeffective for holding them closed,lbut it is a relatively simple matter for an unauthoriiced person to release the latch and open the win.- dow, or door, to which it is applied, to .gainentrance to a building. It is only necessary to. break a window pane or remove a small section thereof, or cut a small hole through a door, and th en reach in from the outside and release the latch after which the window or door may be opened.
This invention, as disclosed herein, is adapted to applied to either single or double swinging windows or doors, and comprises a, locking lever secured to a rotatable stud which is rotatably mounted in a casing secured to a window or door iamb, and is adapted to be swung into or out of engagement with a pivoted latching member car'- ried by a'window or door jamb. Ajkey-operated or combination locking means is provided to lock the lever in engagement with the latching memher when the latching member is in latching position and thus prevent releasing the latching membar by unauthorized persons,
The principal object of the invention is to provide an improved locking mechanism for application to windows or doors to be used in conjunction with standard type latching means thereon.
Another object of the invention is to provide a locking mechanism of this type, which is of simple construction, efficient in operation and which is relatively inexpensive to manufacture.
Other and more limited objects of the invention will be apparent from the following specification and the accompanying drawings forming a part thereof wherein:
Fig. 1 is a front elevation showing my improved Fig. 4 is a horizontal section taken on the line li it of Fig. 1.
The invention as. illustrated herein is shown asapplied to apair; of French type swinging windows which are. adapted to close against a stationary jamb on which is pivotally mounted a pair of latchingmembers, each consisting of .an
operating handle, adaptedto be swung inwardly;
and a, latching finger which projects out through aligned slotsv in the jamb and the window pane.
and into engagement with the outer surface of the window frame to hold it closed.- against the jarnb. The invention comprises alocking lever, secured intermediate its ends to a rotatable stud,
which is adapted to be rotated into and out of engagement with the operating handles to control the operation thereof. A .keysoperated looking mechanismis provided to lock the lever in handle-engaging position.
Referring now' to the drawings by reference charactersthe numeral l indicates a section of a window jamb against which a pair of swinging windows 2are adapted-to abut when closed. Each of the-windows 2 consists of a frame 3 and a glass pane 5 suitably mounted therein. Latching members, generally indicated by the numeral 5, are provided for holding each of the windows 2 in closed. position. Each of these latching members 5. consists of an operating handle 5 and a latching finger l which is formed integraltherewith. Each latch 5 isv pivotally mounted upon a pivot bolt 8 which is supported by inwardly extending ears 9 of a bracket In, which is secured to the jamb l by screws or rivets H. When a window 2 is inclosed position abutting the outer surface of the jamb I the latching finger I is adapted to extend through a slot l 2 in the jamb l and a slot l3 in the window frame 3 which aligns with the slot [2. The latching member 5 is mounted for movement in a plane perpendicular to the jamb i so that in order to unlatch the window 2 the handle 6 is pulled inwardly from the jamb I, which draws the latching finger I in through the aligned slots i2 and I3 and out of engagement with the window frame 3. Reversely, in order to latch the window 2 when it is in closed position against the jamb I, the operating handle 6 is pushed outwardly towards the jamb l which projects the finger I through the slots i2 and I3 and up into engagement with the window frame 3, as shown at M. In order to lock the latching members in latching positions so that the fingers I cannot be withdrawn. from engagement with the window frame 3, I provide a locking mechanism, which is generally indicated by the numeral l5. This locking mechanism comprises a lever 16 which is rigidly secured to the outer end of a shaft II. The shaft I1 is rotatably mounted in a bushing I 8 which is secured to and extends inwardly from the cover I9 of a casing 20. The casing 20 consists of a base plate 2|, the cover I 9 and an annular frame 22 which is disposed between the base plate 2| and the cover I9. The base plate 2I, frame 22 and cover I9 are shown as held together by screws 23 and 36. The casing 20 is secured to the inner face of the jambl by non-removable screws 33 which extend through apertures in the base plate 2|. The shaft I! has a reduced cylindrical end 25 and a square section 24 adjacent thereto. The square section 24 extends between the base plate 2| and the cover plate I9 within the casing 20, and the reduced end 25 extends into a recess 26 in the base plate 2 I. The shaft is held in position within the bushing I8 by a washer 21 which is secured to the end of the shaft II within the recess 26 by a screw therein. In order to prevent the unauthorized turning of the lever I6 and the unlatching of the windows 2, I provide a lock 29 of the lever tumbler type which is mounted within the casing 20. The lock 29 has a locking plunger 30, shown as key-operated, which is adapted to be projected into one of the notches 3I in a disc 32 which is secured to the squared section 24 of the shaft I'I within the casing 20. In order to yieldingly hold the lever I6 in either locking or unlocking position, I provide a spring member 35 of spring wire which is mounted within the casing 20 between the cover I9 and the disc 32 and is held in position by a pair of screws 36. The free ends 31 of the spring member 35 yieldingly engage parallel sides of the squared section 24 of the shaft I I, as shown in Fig. 3 when the locking lever I6 is in either locking or unlocking position. As the lever I6, and with it the shaft I1, is turned from one position to the other, the free ends 31 of the spring will be forced outwardly by the engaging corners of the squared section 24, but will spring back into engagement with the other parallel sides of the squared section 24 as the lever I6 approaches either the looking or unlocking position, where it will be held by the spring member 35 against free movement. After the lever I 6 has been locked in locking position and the locking plunger 30 of the lock 29 has been projected into a notch 3| in the disc 32, the lever l6 cannot be turned to unlocking position until the locking plunger 30 has been withdrawn, by means of the proper key or combination, from the notch 3|.
From the foregoing it will be apparent to those skilled in this art that I have provided a very simple and effective mechanism for accomplishing the objects of the invention.
It will be understood that I am not restricted to the specific construction shown and described herein, as various modifications may be made thereto within the spirit of the invention.
What is claimed is:
} Locking mechanism for securing a window latch adapted to hold a swinging window closed against a jamb and havinga latching finger pivoted to said jamb to engage and hold the window closed and having an operting handle mounted to swing outwardly in a plane normal to said j amb to move said finger into and out of engagement with the window, said handle when in latching position extending alongsaid jamb and having a top surface a portion of which at least is parallel to said jamb, said locking mechanism comprising a casing to be secured to said jamb under said handle, a shaft rotatably mounted in said casing and projecting outwardly threfrom, a lever rigidly secured to the outer end of said shaft and adapted when in locking position to overlie and engage said top surface of said operating handle to prevent outward movement thereof and when in releasing position to extend parallel to said handle, a disc having a notch rigidly secured to said shaft within said casing, a lock in said casing having a. plunger adapted to be inserted into said notch for securing said shaft against rotation with said lever in handle-engagin position, and spring means to align said notch with said plunger.
