SPECIFICATION forming part of Letters Patent No. 744,654, dated November 17, 1903. I Application filed March 28, 1908. Serial No. 150,004. (No model.)
To aZZ whom it may concern.-
Be it known that I, WARREN B. WEAVER, a citizen of the United States, residing at Lakeland, in the county of Polk and State of Florida, have invented a new and useful Sash- Lock, of which the following is a specification.
This invention is an improved construction of sash-lock which can be applied to a window-sash and by means of which the said sash can be locked in either a raised, lowered, orintermediate position With this object in View the invention consists in peculiar features of construction hereinafter fully described, and pointed out in the claims. v
In-the drawings forming a part of this specification, Figure 1 is a perspective viewshowing the practical application of my invention, the sash-lock being applied to the lower sash of a window. Fig. 2 is a detail perspective view showing one corner of the sash and having the sash-lock applied thereto. Fig. 3 is a horizontal sectional view on the line 3 3 of Fig. 2. Fig. 4.- is a view of the lock with the faceplate removed. Fig. 5 is a sectional view on the line 5 5 of Fig. 3, the windowsash being omitted for the purpose of more clearly illustrating 'my invention. Fig. 6 is a detail perspective view of the operatingspring, and Fig. 7 is an enlarge ddetail sectional view taken longitudinally through one end of the bolt. A
In the practical embodiment of my invention I employ a shallow case A, having integral ears A extending from the upper and lower ends of the case. A bolt B passes transversely through the case, adjacent to the upper end thereof, the sides of the case being cut away to permit the movement of thebolt, and in practice I prefer to construct that portion of the bolt which works through the case square in cross-section, and the openings in the sides of the case are correspondingly shaped, so that the bolt willfit snugly therein. The inner end of the bolt is rounded, as shown at B, providing a'suitable handle for operating the lock. The square portion of 'the bolt has an opening B extending vertically therethrough, the opposing edges of the said opening being convexed, as shown at B in Fig. 7, the purpose of which will be ex- A spring 0 is arranged held in place in the case by means of a boss A which is preferably formed integral with the case, adjacent to the lower end thereof, and is adapted to fit 'the bowed portion of the spring, or that portion thereof comprising the lower end of the long member, the entire short member, and the connecting or' bottom meinber, and it will be noted that the basis A is of such a size and shape and is so arranged with referencevto the lower end of the case that when the spring is arranged in said case it will be securely held against displacement and the upper end of the long member will pass through the opening 13'' in the bolt, said end being tapered, as shown at 0 whereby friction is reduced between the bolt and spring. The free end of the oblique member bears against the long member 0 and serves to hold said member normally in such a position that the bolt will besustained in its forwardlyprojected or locked position. A face-plate A is secured upon the case and holds all the parts in their proper positions.
In operation a recess is cut in the edge of the sash for the purpose of receiving the case, and 'a hole is bored from said recess through the side of the sash and extends completely therethrough, and .in this hole the handle of the bolt is designed to operate, the extreme end of the handle projecting slightly beyond the side of the sash, as most clearly illustrated in the drawings. Socket-holes are cut in the window-frame at anydesirable points, and when the window is raised or lowered the bolt will engage these socketholes, thereby holding the window in a locked position, and when it is desired to move the window from one position to another the bolt is withdrawn by pulling upon the handle,and the window can then be raised or lowered, as desired. As soon as the handlefis released the spring operating upon the bolt will project the same into the first sockethole which it reaches, and it will thus be understood that it is only necessary to grasp and hold the handle for a short space of time. By
having the edges of the opening in the bolt convexed the spring will bear evenly upon the said bolt during all of the movements of said bolt, thereby insuring the uniform action of the device.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. A sash-lock comprising a case, a bolt working therethrough, and having an opening therein, a U-shaped spring arranged in the case and having one member longer than the other, the longer member being tapered at its upper end, and projecting through the openingin the bolt, the free end of the shorter member bearing against the longer member, and means for holding the spring within the case, substantially as described.
