SASH LOCK.

ATTORNEYS ENTTED %TA TE% PATENT HENRY I]. KELLOGG, OF BANGROFT, VJISCONSIN, ASSIGNOR OF ONE-HALF 'IO W. A. BUNGE, OF WAUSAU, WISCONSIN.
SASH-LOCK.
Application filed January 27, 1917.
To all whom it may concern:
Be it known that I, HENRY L. KnLLoee, a citizen of the United States, and a resident of Bancroft, in the county of Portage and State of Wisconsin, have invented certain new and useful Improvements in Sash- Locks, of which the following is a specification.
My invention relates to means for locking window sashes, either for adjustment as to the degree of opening, or for the prevention of exterior manipulation as by thieves seeking unlawful entry into a house, or for both, and among the objects of the inventlon are to provide such locks which are very simple in construction, installation, and operation, which are composed of few parts not likely to get out of order, which are highly practical, and which are very inexpensive, thereby adapting the same to the poorer of classes of dwellings, as well as those of a more pretentious class.
My invention is fully described in the following specification, of which the accompanying drawings form a part, in which like characters refer to like parts in each of the views, and in which Figure l is an elevation of the interior of a window of the vertically movable sash type provided with my invention;
Fig. 2 is an enlarged detached view of one of the locks, with part of the casing broken away;
Fig. 3 is a transverse section of the same, and
Fig. 4 is a detached view of a detail.
Referring to the drawings, 5 represents a window frame having an upper sash 6 and a lower sash 7 vertically movable therein, the former having one and the latter two of my locks 8, at 9 and 10 for permitting upward movement of the two sashes and at 11 for permitting downward movement of the lower sash.
Each lock 8 comprises outer and inner plates 12 and 13, respectively, held together as by studs 14, the inner plate being embedded in a mortise in the sash and the outer plate being secured to the inner face of the sash as by two screws 15, in an adjusted position later explained.
The plates 12 and 13 are provided with bores for the reception of the outwardly clirected arms 16 and 17 of a lever 18 having an eccentric or cam-shaped inner end 19, the
Specification of Letters Patent.
Patented Aug. 28, 1'91? Serial No. 144,881.
arm 17 being elongated and angularly bent to form a handle 20 by which said levermay be manipulated, and I. provide a coil spring 21 between a fixed lug 22 on one of said plates and the cam end 19, as is clearly shown in Figs. 2 and 3, the lever 18 being shown as of wire bent into the desired form.
The locks are adjusted in such manner that the cam-shaped ends 19 thereof will bear against the bottom of the sash run and not on the parting strip of the window frame, so that the distance between the axes of the arms 16 and 17 to the bottom of the run will be less than the distance from said axes to the lever end 19, with the result that an attempt at sash movement toward the lever end 19 will result in binding the sash against the opposite side of the window frame, the lever end 19 being in positive engagement with the bottom of the run at the same side of the window frame as the lock, and the sash movement is thus prevented in such direction but, in attempted movement in the opposite direction, said sash will move readily as the lever end 19 will slide along the bottom of the sash run and not resist this sash movement.
If, from the sash positions shown in Fig. 1, it is desired to lower the upper sash all that is necessary is to press the handle 20 in position 9 upwardly to release the cam of this look from the window frame and, when the desired sash adjustment has been accomplished, said handle is released and the spring 21 of this look automatically forces the cam into reengagement with the window frame to lock the said sash against further downward movement, although permitting upward movement thereof, thereby prevent ing unlawful entry.
This is also true with the lower sash, if raised, the handle 20 in the position 10 being forced upwardly and the sash moved downwardly into desired position, the lock in the position 11 not interfering with such downward sash movement but preventing upward sash movement against raising of the sash from the exterior of the window, and, when the handle of the lock in the position 10 is released, the spring of this lock forces the cam thereof into window frame engagement and the sash 7 cannot be moved up wardly or downwardly from the exterior thereof.
My invention is very simple though well adapted to its purpose and does not mar the prominently visible woodwork as do sash locks now known to me and; while I have shown a preferred form of look, I reserve the right to make changes thereover provided such changes do not depart from the spirit of the invention and come within the scope of the following claims.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A sash look comprising two spaced and apertnredplates, and a lever mounted between the plates and formed of a piece of wire bent to form a cam at one end, a handle at the other end, and journals from one of which the handle extends.
2. A sash lock, comprising two spaced and aperturcd plates, a lever formed of a ing from onejournal and with a cam at one end, and a spring forcing said cam outardly of said plates.
3. A sash lock, comprising two spaced plates,a lever formed of a length of wire doubled on itself for a. portion of its length,
bent transverselydn opposite directions to form journals having their bearings in said plates; again bent at one of said arms to form a handle, and said doubled portion curved to form a cam, and a spring interposed between said cam and a lug on one of said plates for forcing said cam outwardly of said plates.
