To all' whom it may concern/.-

Be it known that I, JAcoB B. HARTMAN, a citizen of the United States, residing at Wooster, in the county of Vayne and State of Ohio, have invented a new and useful Sliding Window-Blind, of which the following is a specication.

My invention relates to inside windowblinds, and especially to improved devices for securing and operating the same within the window-frame; and it consists in the novel manner of attaching grooved guidestrips to the Window-frame, and in the novel manner of attaching the guide-strips when the windowjambs are too narrow to sustain the saine within the frame.

My improvements are illustrated by the ac companying drawings, in which Figure l is a horizontal sectional view of one side of a window-frame, showing a jamb and grooved guide for the blinds formed of one piece. Fig. 2 is a similar sectional View showing my improved guide-strip. Fig. 3 is a modified View of the same, showing my improved method of attaching the guide-strip where the jambs are too narrow to sustain the same. Fig. 4 isamodiiied View of the same, showing my improved method of attaching the guidestrip byboxing out the inside casing upon the same. Fig. 5 is a modification showing myimproved guidestrip attached to a beveled or flared jamb.

The opposite sides of the window-frame are of course duplicates of each other; hence only one side need be described.

In the drawings similar letters of reference indicate like parts.

Jis one of the jambs of an ordinary windowframe; E, the outside casing; I), theinside casing. G is my improved guide-strip. S are thesashes; e, the insidesashstop; ande are the series of sliding blinds which are fitted to slide in the grooves of the guide-strips G. The grooves of one of these guide-strips are made deeper than the grooves of the opposite guide- 'strip, as heretofore. Heretofore such grooves were all out alike.

My improvement lies in cutting the rear groove ofthe guide in the edge ofthe samein the form of a rabbet, g, adjacent to the sashes, thus leaving the one side of such rear groove open, the groove being completed by the projecting edge of the `jamb or the sashstop, as

the case may be, against which the guide-strip may be placed. By such means I am able to bring the series of sliding blind-sections closer to the sashes than heretofore, and in cases where the guide is placed back of the front surface of the j amb the rabbeted edge xaforesaid may be secured in a corresponding recess, t, in the edge of the jamb J, and thereby more effectually secure the same. guide-strip may be readily adapted to any form of window-frame. In cases where the inner jamb or casing is beveled or flared, as is generally the casein brick buildings, the guide is beveled upon its rear side to iit the bevel of the casing, as shown in Fig. 5. Heretofore such guides have only been placed upon the window-jainb or set back, so that the face of the same is iiush with the face of thejamb. It will be seen thatlhe grooved guide-strips G are placed back of the front surface of the jambs, respectively, as shown, Figs. 3, 4, 5 thereby giving abetter opening for thelight, and adapting such blinds to be used with window-shades placed between them and the sashes-a feature very desirable in many cases.

By the use of myinvention I am enabled to adapt a guide-strip to a narrow jamb.. This I accomplish by extending the front edge of the guidestrip beyond the front surface of theinside casing, D, Fig. 3, sufficient to afford the room required for the blinds, and placing a beaded strip or molding, a, in the angle formed by the frontsurface of the inside casing and the extended guide-strip, thereby giving strength and beauty of finish to the parts. I also accomplish a similar purpose where the case requires still wider jambs by boxing out the inside casing upon the front edge of the guidestrip, as shown, Fig. 4, thereby forming a iinish in the nature ot' a pilaster on each side of the window, which is highly ornamental. This pilaster may of course be formed in a variety of Ways, the feature I claim being coniined to such extended guidestrip in combination with the inner casing boxed out to support the same.

yIt will be further seen that I can form the winbe used. The grooves being made with the This form of rco frame, the arrangement is simple and less expensive than by the use of a separate guidestrip, as heretofore.l y

Having thus described my invention,what I claim s- 1. The combination, with a Window-frame, of grooved guidestrip G, attached to the j amb so that its outer or front surface is back of the front or outer surface of the jamb J, and a series of blinds fitted to slide therein, substantially as set forth. A l

2. 'Ihe combination, with a Window-fran1e, of grooved guide-strips G, having their front surfaces back of the frontsnrfaces of the j ambs, respectively, and their projecting rear edges, x, set behind the front edges of the jambs, and
