lllNllTEE STATES PATENT @FFTQE BARBARA C. DODDS, OF MINNEAPOLIS, MINNESOTA.
WINDOW-SASI-I LOCK.
To all whom it may concern Be it known that I, BARBARA C. Donne, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Window- Sash Locks, of which the following is a specification, reference being had to the accompanying drawings.
This invention comprehends certain new and useful improvements in window sash locks and has for its primary object to provide a sash lock which may be readily applied to the form and construction of windows now in general use without in the least altering the construction of the same.
A further object is to provide a sash lock of this character which will be of extremely simple construction and highly efficient and effective in use and which may be employed for locking the sashes in either open or closed position and preventing movement of either sash.
A further object is to generally improve and simplify the construction of devices of this character and construct the same of the minimum number of parts, thereby greatly reducing the cost of manufacture of the article and at the same time increasing the efliciency and value of the same.
With the above and other objects in View, my invention consists in certain novel constructions, combinations, and arrangements of the parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a fragmentary elevational view of a window with my improved lock applied thereto; Fig. 2 is a top plan View of my lock in position, a portion of the window frame being shown in section; Fig. 3 is a longitudinal sectional view through my improved lock, said view being taken on the line 3-3 of Fig. 2; and Fig. 4 is a transverse sectional view thereof on the line 44 of Fig. 2.
Referring more specifically to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the plate which is in the form of a strip and is secured upon the upper rail of the lower sash, by he screws 2 or other suitable means and extend toward one end of the rail, the outer end being flush with said end of the rail, as
Specification of Letters Patent.
Application filed May 7, 1913.
Patented Au 19,1913,
Serial No. 766,227.
will be clearly understood by referring to the drawings. The edges of the plate 1 are bent upwardly and inwardly to form guide flanges 3, from the outer end of the plate 1 to within a spaced distance of the inner end of the same. The guide flanges 3 serve to guide the upper or slidable plate 4, which has its longitudinal edges engaged in said guide flanges, the upper plate 4 being adapted to slide longitudinally upon the lower plate 1. The outer end of the upper or slidable plate 4 is provided with spaced sets of outwardly directed teeth 5 with the space (3 therebetween to accommodate the usual weight carrying cord 7 while the teeth 5 engage in the window frame to either side of the cord when the plate 4 is forced outwardly by means of the cam member 8 which is pivoted upon the inner end of the lower or stationary plate 1, as shown at 9, and engages against the upwardly turned inner end 10 of the upper or slidable plate 4. it will be clearly understood that when it desired to move the slidable or upper plate 4 inwardly, the cam member 8 is rotated in the proper direction and the plate 4 drawn inwardly by means of the upwardly turned inner end 10 thereof.
The upper window sash may be readily locked with the lower sash and the upper or slidable plate 4 secured against movement when in either position by means of the clamping screw 11 which has the handle 1%! formed upon one end while its opposite end is provided with the rotatable bearing head 13 for engagement against the side rail of the upper sash, it being understood that the screw 11 has threaded engagement through the upstanding bracket 14 which secured at its lower end to the upper face of the slidable or upper plate 4, near the outer end of the latter.
From the foregoing it will. be apparent that I have provided a window sash lock which may be readily applied to the form of windows now in general use without in the slightest degree altering the construetion of the same and which will be formed of the minimum number of parts of simple construction and which will also be highly efficient and effective in use, it being seen that either sash may be locked in either open or closed position or at any point between said open and closed positions. It will also be apparent that this form of lock may be readily and cheaply manufactured and applied and will be strong and durable as well as highly efficient and'eflective in use.
While I have shown the preferred form of my device it will be understood that I do not wish to be limited to this specific con struct-ion and arrangement of parts as mi nor changes in the details of construction may be resorted to within the scope of the appended claims without departing from the spirit of my invention or sacrificingany of the advantages of the same.
What I claim is 1. A sash lock comprising a lower plate, means for securing the plate upon one sash of a window, an upper plate slidably m0unt ed upon the lower plate, means carried by the lower plate for guidingthe upper plate, said upper plate having its outer end notched to form teeth for engagement in the window sash, a cam member carried by the lower plate and adapted for engagement against the inner end of the upper plate to force the same outwardly, and means carried by the upper plate for locking the same with the second sash of the window and preventing movement of said second sash.
2. A sash lock comprising a lower plate, means for securing the plate upon one sash of a window, an upper plate slidably mounted upon the lower plate, means carried by the lower plate for guiding the upper plate, said upper plate having teeth formed upon its outer end while its inner end is directed upwardly, means carried by the lower plate and adapted for engagement against the inner end of the upper plate to force the same outwardly, and means carried by the upper plate for locking the same with the second sash of the window and preventing movement of said upper sash.
In testimony whereof I hereunto ailiX my signature in the presence of two witnesses.
