SASH-FASTEN ER.
SPECIFICATION forming part of Letters Patent No. 408,920, dated August 13, 1889.
I Application filed March 25, 1889x Serial No. 304,606. (No model.)
To all whom it may concern..-
Be it known that we, CHARLES H.r MILLER and SAMUEL A. MCDONALD, of Decatur, in the county of Vise and State of Texas, have invented a new and useful Improvement in Window-Fasteners, of which the following is a full, clear, and exact description.
Our invention relates to an improvement in window-fasteners, and has for its object to provide a device of simple, durable, and economical construction, capable of attachment to any window, and of convenient manipulation.
A further object of the invention is to provide a device whereby a window may be effectually locked in an open, in a closed, or in any desired position.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter more fully set forth, and pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding` parts in all the views.
Figure 1 is a partial front elevation of a window-frame, illustrating the application thereto of the device. Fig. 2 is a vertical section through the window, the device being in side elevation. Fig. 3 is a section taken partially on line a; cc of Fig. 1; and Fig. A is avertical section of the bracket, the thumb-lever being in side elevation.
In carrying out the invention a strip or bar 10, preferably of spring metal, is provided, having its ends bent slightly downward and outward, whereby when the said ends of the bar are attached to the stile of the windowframe, as illustrated in Fig. 1, the body of the bar will be elevated a distance from said stile, as best shown in Fig. 2. The strip or bar 10 is preferably rectangular in cross-section. To the inner face of the window-frame 11, in front of the sash, a bracket 12 is secured, which bracket is preferably angular, as illustrated in Figs. 1 and 4, consist-ing of a vertical member a and a horizontal member a.
Vhen the bracketis made in the form above described, it is attached to the window-frame by passing screws or equivalent fastening devices through the vertical member into the said frame, apertures 13 beingproduced in the said vertical member to that end, as shown in Fig. 3. The horizontal member of the bracket, which constitutes the body thereof, is provided with a vertical aperture or opening 14, the walls whereof are inclined from the center outward, as illustrated at 15 in Fig. 3, whereby the said aperture or opening is wider at the top than at the bottom. Before attaching the bar 10 to the stile of the window-sash the lower end of the said bar is passed through the opening or aperture 14 of the bracket, and in the vertical member of the bracket one end of a thumb-lever 16 is hinged to have a vertical movement, the opposite end of which lever extends parallel with and beyond the horizontal member of the bracket, as best shown in Figs. 1 and 4f. The thumb-lever 1G, immediately above the opening 14 in the bracket, is provided with an integral preferably wedge-shaped lip 17,
concavo-convexin cross-section, as best shown in ig. 3.
In operation, when the window has been carried to the desired position, the thumblever being out of engagement with the horizontal member of the bracket, to retain or lock the window in such position, the thumblever is pressed down, whereupon the lip 17 enters the opening 14E in the horizontal member of the bracket and contacts with the inner or under face of the bar 10. This movement of the lever is readily accomplished by reason of the yoke-like form of the bar 10 and by reason of the fact that the lever passes from the vertical member of the bracket outward to the rear of the bar, as shown in Fig.v
1. As the upper portion of the opening 14 is wider than the lower portion, and as the lip is concavo-conveX in cross-section, when the said lip is forced down into the bracket-opening, the strip or bar 10 is kinked, as illustrated in Fig. 3. Thus a curve is produced at the point of contact with the lip, and at vsaid point of contact the said bar is firmly wedged between the fixed surface of the lip and one tapering wall of the opening.
It will be readily observed from the foregoing description and by reference to Fig. 3 of the drawings that when the parts of the de- IOO and parallel with the horizontal member of Said bracket, and a lip integral with the nnder edge of the lever, eoncavo-convexin cross- Section, and capable of entering,I the opening;l in the bracket and contacting with the inner or under face of the yoke-like bar, all combined for operation substantially as shown and descrilmd.
