M. K. MAYNARD v WINDOW LOCK Filed Jan. 21, 1924 Patented Mar. 2, 19269 PATENT oEFicE.
MARK K. MAYNARD, OF GOLTON, WASHINGTON.
WINDOW LOCK.
Application filed. January 21, 1924. Serial No. 687,538.
To all whom may concern:
Be it known that I, MARK K. MAYNAro, a citizen of the United States, residing at Colton, in the county of Vhitman and State of \Vashington, have invented certain, new and useful Improvements in \Vindow Locks, of which the following is a'specification.
This invention relates to improvements in window locks, and has for its primary object to provide such a lock, wherein the window may be positively maintained against upward or downward movement in a partly opened or closed position.
A further object of the invention is to provide such a window lock that may be applied to practically all types of window frames wherein there are positioned sliding sashes, in a novel, simple, and expeditious manner. 1 a
A still further object of the invention is the provision of such a window lock, that is extremely efficient in operation, and highly useful for the purposes intended.
The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination, and arrangement of parts as claimed.
In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:
Figure 1 is a fragmentary sectional view, through a window frame equipped with my improved lock, which lockv is shown partly in side elevation, and partly in cross section.
Figure 2 is a fragmentary plan view of the inner side of the window frame that carries my improved lock, together with said lock, and
Figure 3 is a perspective of one of the wing-shaped spring pressed. jaws, that is included in my lock.
Now, having particular reference to the drawing, 5 designates generally a window frame, and 6 one of the sliding sashes with in said window frame.
My novel lock comprises a suitable form of easing 7 that is open at its inner edge, and positioned within an opening of the frame 5, and in longitudinal alinement with said sash G. The inner side of said frame 5 surrounding said opening 18 mortised for the reception of a lock plate 8, that is maintained in position by wood screws 9, and
that is formed with a pair of spaced oblong openings 10, for purposes presently to be set forth.
Within the lock casing 7 adjacent the open edge thereof, and in vertical alinement with each other is a pair of wing-shaped jaws 11, the outer edges of which are toothed at 12 in reverse directions to each other. As more clearly shown, in Figure 3, each of the said jaws 11 is formed with a circular head 13 upon the opposite ends of which are pintles 1 1 for engagement within openings of the side walls of the casing 7, whereby the same have free swinging move ment within the casing towards and away from the adjacent edge ofthe frame of said sash 6.
Each of the jaws 11 are channeled upon its inner side at 15, and surrounding the portion of the head 13 of said jaws coextensive with the channel 15 is a spring 16, one end of which has engagement with the edge of the channel, the opposite end having engagement with the adjacent side of cross guides 17, whereby these jaws are normally maintained in the position of Figure 1, that is, in engagement with the adjacent side of the sash frame, for preventing the raising or lowering of the sash.
Slidable between the said guide plates 17 is a head 18, the front end of which is curved for engagement with the adjacent portions of the jaws-11. The opposite end of this head is notched as shown in Figure 1, for receiving the bent end of a finger 19, that is carried by a shaft 20, and extends through openings in the side walls of the casing 7, as well as extending through an opening in the window frame 5, and projecting outwardly thereof for receiving a key 21, whereby said shaft may be rocked.
It will be apparent from the above description when considered in conjunction with the accompanying drawing that the jaws 11 are normally in the position shown, that is, extending through said openings 10 in the plate 8, and having engagement with the adjacent side of the frame of the sash 6, for preventing the sash from being raised or lowered? A, t rn g f the shaft 20 in for allowing the sash to be raised or,
lowered.
Numerous advantages of a Window lock of this character will be readily appreciated by those skilled in the art, and although I have herein shown and describedtheiproferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made tlierein, without departing from'the spirit and scope of the invention as claimed.
'I-Im'ing thus described 'my invention,
havin -"end" portions passing through the side-of the same and having inner end portions engaging the head, springs coiled around thei-pivots-of the jaws and engaging the guide plates and the jaws and a shaft journaled in the casing andhaving-a finger engaging; the liead.
'In; testimony whereof I aflix my signature. s s
