WINDOW-LOCK.
Specification of Letters Patent. Patented U013, 16, 191i 7..
Application filed August 22, 1916. Serial No. 116,316.
To all whom it may concern:
'Be it known that I, UNITED S. JAoKsoN, a citizen of the United States, residing at Copperfield, in the county of Baker and State of Oregon, have invented certain new and useful Improvements in Window-Locks, of which the following is a specification.
This invention relates to a window lock and more particularlyto a device for automatically locking a window in open or closed position.
The primary object of the invention is to provide a lock whlch will prevent intruders from gaining access to the mechanism of the lock so that the window can only be opened from the interior of the building in which the window is situated.
A. further object of the invention resides in the rovision of a lock that will be automaticaliy unlocked when the window lifts are engaged to, raise the window and'which will automatically lock itself in raised position when the window lifts are released.
A further object of the invention is the provision of a structure that will have the locking mechanism arranged within a casing sunk into the window sash and covered by a plate which carries the window lifts the window lifts being so constructed as to present a flat and even surface thereb obviating the other projecting window 1i ts.
A further object of this invention is the provision of a window lock which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.
. For a full description of the invention and the advantages and merits thereof, reference is to be had to. the following description and the accompanying drawings, wherein is illustrated the-preferred form of my invention, in which;
Figure 1 is a fragmentary front elevation of a window sash showing the locking mechanism in dotted lines.
Fig. 2 is a central vertical section.
Fig. 4 is a horizontal transverse section on the line 1-4 of Fig. 1. A Fig. 5 is a detail perspective view of the latch. i
Fig. 6 is a side elevation of the wearing plate for the window and casing.
'by forming slits- 6 in the rear Wall 7 of the casing, the material embraced by the slits being bent at right angles from thewall and curved to provlde the retaining arms 8 for the sliding bolt 9. Depending from the sliding bolt 9 is a lug 10 which carries a horizontally disposed stud 11 to receive one end of a coiled expansion spring 12. As shown by Fig. 3 of-the drawing, the end wall of the casing carries a stud 13 which is similar to'the stud 11 and receives the opposite end of the coiled expansion spring 12. This spring 12 tends to force the bolt 9 outwardly through a circular openingin the end of the casing which is flushed with the edge 2 of the window sash. The bolt, therefore, is merely extended for a slight distance and is received in any one of the apertures 14 formed in the wearing plate 15 which will be attached to the window casing so that the edge 2 of the window sash is in sliding engagement with the wearing plate 15.
A retaining plate 16 is mounted in a re' cess in the face of the sash and extends slightly above the casing 4 at its upper end and considerablybelow the lower portion of the casing as shown by Fig. 2 of the drawing. This plate 16 is provided with bear-.
' ings 17 which receive the ends of the pivot bolt 18 carried by the window lift 19. The
dow lift to swing inwardly the interior of the casin when the lower end 23 of the window lift is raised to horizontal position for lifting the window sash. A finishing plate 24 is mounted on topof'the plate 16 and is held in engagement with the window sash by the fastening screws 25 which also pass through openings in the plate 16 so that both plate 16 and the plate2 1 are securely held in the depression in the surface of. the window sash. The finishing plate 24 lies flush with the face of the window sash and the window lift 19 also lies flush with the finishing plate 24 so that a perfectly plain and unobstructed surface is presented by the finishing plate and the window lift.
Pivotally mounted upon the rear wall 7 of the casing 4c is the latch 26 which has an opening 27 for receiving the pivot pm 22}. An upwardly extending curved arm 29 1s integrally formed with the hub of the latch and the end of the arm engages the lug 10 so that the coiled expansion spring 12 tends to hold the latch in the position shown by dotted lines in Fig. 1. An operating finger 30 is also integrally formed with the hub of the latch and is curved to extend toward the front of the casing and has its end terminating in a position so that it will be in the path of the upper end 22 of the window lift 19 when the same is swung inwardly of the casing.
To raise the window sash, the person raising the window will first press inwardly on the upper end 22 of the window lift 19 thereby causing the lower end of the window lift to project outwardly and will permit the person to place his finger under the lower end of the lift. A continued upward pressure on the end 23 of the window lift will cause the end 22 of the window lift to engage the operating finger 30 of the latch thereby slightly rotating the latch and causing the member 29 to exert a pressure upon the lug 10 thereby sliding the bolt 9 111-- wardly against the pressureof the spring 12. The whole operation is thereby accomplished by the simple lifting of the window lift. When the window lift is released the coil spring will force the bolt back to extended position and the return rotary movement of the latch will throw the window lift back to its original position. For lowering the window the same operation is followed with the exception of the pressure which is applied to the window lift as in this instance, the downward pressure must be directly over the pivot bolt 18 of the window lift so that the bolt will be held in the casing while the window is being lowered.
From the foregoing it will be observed that a very simple and durable window lock has been provided, the details of which embody the preferred form. I desire it to be understood however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claim hereunto appended.
I claim:
A window lock comprising a casing mounted in a window sash, the latter being provided with a relatively deep recess for the reception of the casing, a retaining plate countersunk in the face of the sash and extending over the said casing, a finishing plate overlapping the said retaining plate and rigidly fixed thereto, the retaining plate I having an opening formed therein, a window lift pivotally mounted, the finishing plate having an opening for snugly receiving the window lift, one end of the window lift being adapted to extend through the opening in the retaining plate whereby the opposite end may extend outwardly from the finishing plate, latch means mounted within the casing for pivotal movement, locking means co-acting with the said latch means when the latter is operated, the said lifting plate contacting with the latch means when pivotally moved.
In testimony whereof I afiix my signature in presence of two witnesses.
