SPECIFICATION forming part of Letters Patent No. 749,041, dated January 5, 1904. Application tiled September 5, 1903. Serial No. 172,033. (No model.)
To a/ZZ whom it may concern:
Be it known that I, WLADISLAW DZINK, a subject of the Emperor of Germany, residing at Duquesne, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Window- Locks, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in locks, and relates particularly to locks adapted for use in connection with windows for locking the sash in the closed or partially-open position and acting also to support the window-sash in lieti of the ordinary cords and weights.
Briefly described, the invention comprises a substantially L-shaped casing, in the shorter leg of which is pivotally hunga latch for engagement with a catch carried in the window-A frame. a rod which works in the longer leg of the casing and which rod has a projection protruding through a slot in the front wall of the casing, and to this projection is pivoted a handle by means of which the rod may be operated to retract the same to disengage latch from the catch. The latch is hel'd normally projected in its locking position by means of aspring, and means is provided for holding the latch retracted when desired.
The above construction will be hereinafter more specifically described and set forth in detail, and in such description reference will be had to the accmpanyingdra'wings, forming a part ofthis application,and wherein like numerals of reference will be employed for designating like parts throughout the different views, in whichy Figure 1 is a front elevation of a window and Window-frame, showing my improved lock in position thereon. Fig. 2 isa transverse vertical sectional view of the windowframe. Fig. 3 is a partial side and partial longitudinal section of the lock. Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 3. Fig. 5 is a front view with the casing partly in section to show the pivot of the latch. Fig. 6 is a transverse vertical sectional view taken on the line 5 5 of Fig. 4,
and Fig. 7 is a detached detail perspective This latch is'pivotally connected tov Ycent to the window-frame.
dinal leg 1 of the casing is provided with an i apertured lug 3, and the vertical leg 2 is provided at its upper and lower ends with like apertured lugs 4, these lugs being adapted to receive securing means, such as screws, for fastening the casing in position. The casing is countersunk in the sash-rails,the outer face of the longitudinal leg 1 being flush with the outer face of the lower rail of the sash and the face-plate of the vertical leg 2 being Hush with the face of the sash-rail that is adja- Pivoted in the upper part of the vertical leg 2 and projectf ing through an opening 5 in the front plate of said leg is a latch 6, which is shouldered od near its lower end and has pivotally connected to this shouldered-offportion the outer end of the operating-rod 7. This operatingrod is guided by a slotted integral web 8 and carries au angular lug 9 on its rear end, to which is pivoted a` handle 11, that extends through a slot 10, provided therefor in the front plate of the casing. At the ends of the slot 10 are notches 10 1l-', respectively, into which the handle 11 is engaged for locking the latch 6 in the retracted and projected positions. The latch is retained normally in the engaging position by means of a spring 14, arrangedon the rod 7 between the web 8, and an integral collar 15, carried by said rod. The side Walls of the shorter leg of the casing are provided with bosses 16, as shown in Fig. 5, which gives greater bearing-surface for the pivot-pin 17 and also prevents lateral movement of the latch. Countersunk in the rails of the frame 18 are the catches 19 to be eugaged bythe latch for supporting the sash in the open position.
The casing and lock just described are designed particularly for use on the lower sash, and for the upper sash I employ the same form of lock, the only difference in construction being that I provide the casing 1 in its upper face with a slot 2 to receive the pivoted handle l1, which is engaged in a notch 3 at the rear end of the slot when it is desired to hold the latch 6 and rod 7 in the retracted position. This casing is constructed in this manner, so that the projecting handle 11 will not interfere with the raising of the lower sash or the lowering of the upper sash. It will be observed that only the one notch 3', that for holding the rod 7 retracted, is required in the casing for the upper sash, as when the Window is closed orin the raised position it cannot be further raised. With the lower-sash lock, however, the engaging ofthe handle iu the notch 1l holds the latch in the projected position, and consequently prevents the lifting of the lower sash until the rod and latch are retracted.
Having fully described my invention, what ating-rod and projecting through the slot in the casing, substantially as described.
In testimony whereof I aflix my signature in the presence of two witnesses.
WLADISLAW DZINK.
