SPECIFICATION forming part of Letters Patent No. 505,889, dated October 3, 1893.

Application tiled December 1, 1892. Serial No. 453,744. (No model.)

To all whom t may concern:

Be it known that I, GEORGE W. STROUD, of Chicago, Illinois, have invented certain new and useful Improvements in Window-Frames, of which the following is hereby declared to be a full, clear, and exact description, sufficient to enable others skilled in the art to make and use the same.

The invention designs to provide a window frame of peculiar structure whereby the sash can be taken out or replaced as desired, without the need of removing or disturbing any of the usual frame-parts, such for example as the inside or outside stops. In preferred form, the stops referred to may remain permanently affixed in place; provision being made for shifting a section of one of the stiles and parting strip into the side-box of the frame so that clearing space is afforded sufficient to allow the sash or sashes in turn to be lifted out and away from their position on the frame or be returned thereto, as desired.

The exact nature of the improvements will appear from the description and be pointed out by claim at its conclusion.

Figure l is a cross-sectional view of the improved window-frame showing the position of the lower sash before removal. Fig. 2 is a like view showing the position of the upper sash in course of removal. Fig. 3 is a view of the frame with the sashes in position; Fig. 4 a detail View at the front face of the frame side-box; Fig. 5 a perspective View of the movable section of the pulley-stile and parting strip.

The improved window-frame is constructed for the most part in usual fashion and in the form shown is furnished at its sides with boxes sufficiently large to receive the weights which serve as a counter-poise for the shifting window sashes. The box A consists of the familiar blind stop a and inside casing b extending from top to bottom at the sides of the frame. Between these parts at the front are mounted the pulley-Stiles c and the parting-strips d which latter serve as usual to guide and retain the separate sashes at one side of the frame. The pulley-stile instead of being continuous from top to bottom is divided transversely together with the intermediate parting-strip into two sections, one

of whichis fixed to the frame `and the other movable, the latter being sustained byhinges or like expedient so as to retreat when desired into the box A. A Y For convenient removal of both sashes the retreating section referred to is ordinarily arranged as shown by Figs. 3 and 4 at thelower inner face of the frame side box and consists of the stile c having the parting-strip d fastened thereto in part at the edge of the s tile but with its upper end free so as to yield slightly when pressed by the thumb. The movable section referred to is secured through the hinges e to the companion fixed stile and in such fashion that when the movable section is in place it constitutes with the fixed part a continuous guide-Way for the sashes from top to bottom of the frame. For snugness of lit, the joint f between the two sections is generally cut upon a bevel and a mortise bolt g carried by the retreating section projects into the inside casing b and thus holds the section snugly in place. Said section must be slightly longer than the largest sash which it is desired to take out or toset in placeand acts somewhat as a gate to admlt for clearance and passage of the sash when the latter is turned slantwise for the purpose. Ordinarily the retreating stile section or gate, will be in yposition shown by full ligues, Fig. 1, and in such relation will act the same as if the stile were of the usual stationary kind. To remove the inside or lower sash it is first raised to its topmost limit in the frame, the bolt g Withdrawn and the free end of the parting-strip d pushed inward until itstands iiush with the front face of the stile section to which it is joined in such position; the stop d' clears the lower edge of the up-lifted sash, then adjacent thereto and turns with the stile c about the hinges e into the box A. The sash B can then be lowered toits usual place and by sidewise pull and thrust, be removed from the frame (see dotted lines Fig. l) the stile section having retreated wholly within the box and oering no impediment to this shifting movement since the section is then located as displayed by Fig. 1 (dotted lines). To remove the upper sash C,itv is merely necessary that the same be lowered to position ordinarily occupied by the companion sash B IOO and then be pulled forward slantwise (Fig. 2), thus clearing the space ordinarily occupied by the stile section and being ultimately withdrawn from the frame.

Obviously, the gate like section can be set in the upper instead of the lower part of the window frame or be arranged at the outerinstead of the inner side of the vertical stile. It is merely necessary that the movable section be long enough to afford clearance for the longest sash which is to be taken out or set into place. Where these sashes are mounted without an intermediate Weight, the Window frame should be tted with side boxes sufliciently large to receive the retreating stil'e section. It is clear that devices other-Ethan hinges can be used for sustaining the movable section and yet permit its shifting to be accomplished. y

Modifications in structure can be made according to the skill of the mechanic without departing from the spirit of the invention.

Having thus described my invention, what I claim as new,and desire to securebyLetters Patent, is-

The combination with the sash, of the sidey GEORGE W. STROUD. Witnesses:
