FIXTURE FOR SLIDING BLINDS.

SPECIFICATION forming part of Letters Patent No. 353,858, dated December 7, 1856.

Application filed July .24, 1886. Serial No. 209,009.

To all whom it may concern.-

Be it known that I, \VALTER A. HoLBRooK, of the city and county of Milwaukee, and State of Wisconsin, have invented certain new and useful Improvements in Fixtures for Sliding Blinds; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The objects of my invention are, first, to ap' ply sliding blinds to finished windows without changing or mutilating the window frames or finish already in use; second, to provide suit able boxes or inclosures for eounterbalancing weights or cords of connected sections; third, to utilize the runway-strips as parts of said boxes or inclosures, and, fourth, to utilize said boxes for sash-stops. These objects I attain by the peculiar construction and arrangement hereinafter described. b

In the accompanying drawings like letters refer to the same parts in the several figures.

Figure 1 is a horizontal section of one side of a window frame and finish to which my improvements are applied, and Figs. 2, 3, and 4 are like views of modified forms and ar' rangements.

For convenience of illustration I have shown but one side of the window-frame, 'it being understood, of co arse, that the other side is the counterpart of that shown.

B B are window-sashes, F F the windowjambs, and G G the inside casing.

L L represent a series of blind-sections arranged to slide vertically in thegrooved runway-strips G G. The blind-sections may be connected by cords with and counterbalanced by each other in pairs, or may be hung with counterbalancing weights E E, connected therewith by means of cords or chains which run over pulleys ea in said runway-strips G O. The weights E E run'in boxes formed therefor by inclosing aspace at each side of the window between the jambs F F, or window-finish, and said runway-strips.

H H are L-shap'ed metallic strips secured in an upright position inside of said boxes when (No model.)

The number of blind-sections employed may be varied as desired to suit the requirements of taste or of different constructions. A part or all of the sections may be hung with counterbalancing-weights, or a part or all may be provided with springs or cams in the usual way; or the sections may be connected in pairs by cords and arranged to counterbalance each other. \Vhen weights are employed, removable sections are made in the usual way in the weight-boxes, preferably in the runwaystrips C O, forming a part thereof, in order to get at said weights when desired.

Referring to Fig. 1, 0 represents the runwaystrip grooved upon its inner face to receive and guide the-edges of the blind-sections L L, and forming the inner side of the weightbox. A is the back side of the weight-box, which takes the place of the ordinary sash-stop in retaining the lower sash, B, in position in the window-frame. The front side, D, of said weightbox may be molded in various known forms to harmonize with the surrounding finish. Where the jamb F is sufficiently wide to permit of it, the front side, D, ofsaid weightbox can be finished against the inner face of said jamb instead of covering or overlapping its front edge, as shown in Fig. 1.

In Fig. 2 is shown an arrangement of the runway-strip O and weight-box similar to that shown in Fig. 1, except that for want of sufficient width of the jamb F the front side, D, of said weight-box is set in front of and overlaps the casing G. Fig. 8 shows a similar construction, in which the weight-box is placed in a space commonly formed in finishing brick or stone buildings by setting the jamb-lining I back or outside of the jainb F. \Vith this construction the ordinary sash-stop, J, retains the lower sash, B, in position in the usual manner. In Fig. 4, illustrating an arrange ment similar to that shown in Fig. 1, the runway-strip O is grooved on its outer face adjacent to the window frame or jamb to receive and form boxes for the weights E E or cords when connected counterbalancing-sectious are used, the runwaystrip,sash-stop, and weightboX being thus formed integrally of a single piece. In this construction themetallic division-strips L L are dispensed with, the tongues left between the grooves serving to separate the weights E E. I

- Theseveral constructions shown in the draw ings may be readily applied to windows finished in"tl 1e usual way without changing or niutilating the window frame or finish, the weight-box being made separate from and attached to the inner face of the jamb or jamblining, which may serve as one side of said box. .The combined weight-box and runwaystrip, taking the place in Figs. 1, 2, and 4 of the ordinary sash-stop, are secured to the window frame orjamb by means of screwsor fastenings in such a Way as to be readily removed when desired, and in the several con structions shown the weight-boxes and the runway-strips, forming a part thereof, may be removed from the window, leaving the frame and finish. complete and intact. When the weight-box or runway-strip is set inside of the window frame or jainb, as shown in Figs. 1,2, and 4, shorter blind-sections can obviously be used.

Instead of grooving the runway strips 0, they may be provided with tongues arranged to work in grooves formed therefor in the edges of the blind-sections L. In short, the details of my improvements may be variously modified without departure from the spirit of my invention.

1 I claim 1. The combination, with a window frame and finish, of a detachable blind-weight box applied to the inner face of the window-jamb and bearing against the window-sash, and a runway-strip forming the inner face of said weight-box, substantially as and for the purposes set forth.

2. The combination, with a window frame and finish, of a series of sliding blind-sections, a weight-box the inner side of which is set in from said frame or finish, inclosing therewith a space for the blind-weights, and a runwaystrip forming the inner side of said weightforth. I 3. The combination, with a window-frame and finish, of a series of sliding blind-sections,

a weight-box the inner and front ,sides'of which are built in from and inclose a blindweight space with the finished inner face of the jamb or jamb lining which forms the outer side of said box, runway-strip O, forming the inner side of said box, weights E E, and pulleys a a,-set in said runway-strip'O, substantial] y as and for'the purposes set forth.

4. The combination, with a windowframe, of a weight-box the inner and front sides of which are formed separate and are builtin from said frame, inc-losing therewith a space for the blind-weights, runway-strips 0, forming the inner side of said weight-box, the L-shaped divisionstrips H, attached to said box. substantially as and for the purposes set runway-strips O, and the sliding blind-sections L L, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence of tWo witnesses.
