GUIDE-FRAME FOR SLIDING WINDOW-VBLlNDS.
SPECIFICATION forming part of Letters Patent No. 362,854, dated May 10, 1887.
Application filed February 23, 1886. Serial No. 192,779.
To aZZ whom, it may concern.-
Be it known that I, GEORGE POPPERT, of Milwaukee, in the county of Milwaukee, and in the State of Visconsin, have invented certain new and useful Improvements in Guide- Frames for Sliding XVindow-Blinds; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to guideframes for sliding window-blinds; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter.
In the drawings, Figure l is a front elevation of a windowcasing with Iny invention applied thereto. Fig. 2 is a transverse horizontal section, and Fig. 3 is a vertical section at right angles to the sectiou-line of Fig. 2, through the guide-frame and adjacent parts; and Fig. 4t is a perspective view of one of the springs.
A represents one of the jambs or side boards of the window-easing, and a a are the ornamental strips concealing thel edges of the same, while B B designate the casings of the guideframes C. These easiugs I3 are like boxes, open at one side and at the top and bottom ends, and are. placed vertically against the side boards, A, and strips a. of the window casings, and secured thereto by screws b b, as shown, or otherwise. as most convenient.
The guide-frames C consist of vertical strips, of a width to enable them to just fit inside the box-like easings B. On their inner or concealed sides these frames C are preferably smooth, and are adapted to bear against the springs D D, which are secured, preferably, to the casiugs IS, (though obviously the said springs may be secured to the inner side of the frames C instead.) The outer side of the frames C is provided with a series of beads, c c c, (three in the illustration given,) while between each bead the surface of the frame is rounded, so as to present no sharp corners or angles for the lodgmcnt of dirt.
The edges of the Stiles c ofthe sliding blinds (No model.)
E are furrowed out to forni coves e', corresponding to the shape of the said beads c, on which the blind -stiles slide. Each blind slides freely up and down on the beads of the guideframe, and is held in any preferred position in which it may be left by the expansive force of the springs D D, which are always concealed from sight, and hence are kept clean and in order without trouble, and at the same time will always yield sufficiently,v to enable any blind to be removed at any time, if desired, and to be readily replaced.
In order to prevent the frames G from being sprung away lfrom thecasing, screws b b' are passed through smooth holes in the casing from the rear into the adjacent side of the said frames C, and holes or pockets a a are formed in the jambs A to receive the heads ofthe said screws b when the frames are pressed into tbeir boxes or easings B against the force of the springs D. Inasmuch as the casings B and frames C are thus united together, in order to secu re the casing B to the jamb A, holes bt b2 are provided in the frames C to admit ofthe passage of the screws b and a screw-driver to drive them to place.
Having thus described my invention, what] claim as new, and desire to secure by Letters Patent, is-
In a guide-frame for sliding wiiulow-blinds, the combination of suitable boxes or casings, movable vertical guide-strips, springs interposed betweeu the said parts, and screws passed through holes in the casing and secured to the adjacent surface ofthe guide-strip, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
