REVO LVING WIN DOW-SASH.

SPECIFICATION forming part of Letters Patent No. 554,231, dated February 11, 1896.

Application filed July 5, 1395- Serial No. 554,995. (No model.)

To caZZ whom it may concern: tically-movable stiles or bars K. The stiles Be it known that I, AROHIBALD L. BOLLES, or bars K are preferably of the same length a citizen of the United States, residing at the as a window-sash with which they are concity of Brooklyn, in the county of Kings and nected, and secured to these stiles or bars in 5 State of New York, have invented anew and any preferred manner are the cords M, by useful Improvement in WVindow-Sashes, of which the windows are supported, said cords which the following is a specification, refcrbeing connected with weights N, arranged in cnce being bad to the accompanying drawhousings at the sides of the frame in the ings, forming a partthereof, in which similar usual manner. 10 letters of reference designate like or equiva- Each of the stiles or bars K is provided on. lent part-s wherever found throughout the its outer side with a plurality of springs 0, several views. which are preferably three in number, one at My invention relates particularly to imeach end and one in the middle, and these provelnents in the supports for window springs, or the upper and lower ones, are 6 5 I 5 sashes, and the object thereof' is to provide adapted to bear upon the inner surface of the means whereby the sashes may be revolved sides of the frame. so as to provide means for the proper venti- The springs O are plate-springs, and the lation of apartments, and also to provide ends of the upper and the lower springs are supports for window-sashes which are propreferably directed outwardly and the convex 2o vided with counterbalance-weights and which surface thereof inwardly, and the ends of the maybe raised or lowered and which may also middle springs are preferably directed inbe revolved at any point at which they may wardly and the convex surface thereof outbe supported; and with these and other obwardly, and passing through to the middle jects in View the invention consists in the springs are the pivot-pins P, by which the 25 construction, combination, and arrangement window-sashes are supported, said pins being of parts hereinafter described and claimed. secured in the sash-frames and revoluble in The invention is fully disclosed in the folthe said stiles or bars and in the springs lowing specification, of which the accompathrough which they pass and being provided nying drawings form a part, in which with heads on their outer ends which hold 0 Figure 1 is a side elevation of a windowthe springsin place. frame, together with the window-sashes The central portions of the inner vertical mounted therein, said window-sashes being sides of the stiles or bars K are convex in supported according to my invention and the cross-section, as clearly shown at R in Figs. upper sash being slightly tilted on its pivotal 2, 3, and 4, and the corresponding parts of the 8 5 5 supports; Fig. 2, a section on the line 2 2 of sides of the frames of the window-sashes are Fig. 1; Fig. 3, a section on the line 3 3, and concave in cross-section, as shown at S in Fig. 4 a section on the line 4 at. Figs. 1, 3 and 4, and when the window-sashes In the drawings forming part of this speciare closed, as shown at the lower part of Fig. fication, A represents the verticalbars of the 1 and in cross-section in Fig. 3, the vertical 4o usual windowframes, B the top thereof, and convex portions of the stiles or bars fit Within 0 the bottom, and the side bars A are prothe vertical concave portions of the sides of 'vided with the usual beads or strips D, E, and the window-sashes, and there is a narrow F, between which the separate sashes are space between the stiles or bars and the sides mounted, and in the practice of my invention of the frames, as shown at T in Figs. 1 and 3. 5

5 I support the separate sashes of the windows, The stiles or bars K are of such depth as to which are shown at G and H, in the following project beyond the beads or strips D, E and manner: F, and whenever it is desired to open or re- The separate vertical beads or strips D and volve one of the sashes on its supports it is F form two vertical spaces, in which the only necessary to catch hold of either the 50 sashes are mounted in the usual manner, and lower or upper end thereof and to pull inin each of these vertical spaces 1 place verwardly or shove outwardly thereon, as will be readily understood, and this operation will result in turning the sash on its pivotal supports, as shown in Figs. 1, 2 and 4, and in this operation the stiles or bars K are forced outwardly, so as to fill, or nearly fill, the space T between the same and the sides of the window-frame, and by reversing this operation the sash may be returned to the closed position, in which position the stiles or bars K will be forced inwardly by the springs O, as shown in Figs. 1 and 3.

It will be understood, of course, that either of the sashes, the upper or the lower one, may

be turned or revolved independentlypf the other, or that both of said sashes may be turned or revolved together, and it will also be understood that when it is desired to revolve the lower sash it must be raised, so that the lower side thereof will be freed from the strips or beads of the bottom of the frame, and when it is desired to revolve the upper sash the same must be lowered, so that it will be removed from the strips or beads at the top of the frame, which are not shown.

In the construction herein described, the pivot-pins P, or the outer ends thereof, are secured to the central springs O, and said pivot-pins are free to slide in both the stiles or bars K and the sides of the frames of the window-sashes, as will be readily understood, and by reason of the vertical convex central portion of the outer side stiles or bars K, and the corresponding vertical concave central portion of the outer sides of the frames of the sashes, the operation of revolving the said sashes is rendered simple and effective, and the sashes are held stationary and securely at any desired point by means of pressure exerted by the springs O, and in these features of construction my improvement differs from all devices of this kind heretofore employed.

Having fully described my invention, I claim and desire to secure by Letters Patent- 1. In combination with awindow-frame, of the usual form, of the vertically-movable stiles or bars having a convex outer surface, cords attached to weights passing over rollers or pulleys in the frame of the window, the opposite end of said cord being attached to said stiles, window-sashes having a concave longitudinal groove in the edges thereof adapted to receive the convex portion of said stiles, flat springs secured at each end and the middle of said stiles, pivot-pins passing through said stiles and said middle springs and connectin g the vertically-movable stiles and the frame of the sash, whereby said sash maybe tilted in any position, substantially as described.

2. In combination with awindow-frame, of the usual form,of the vertically-movable stiles or bars having a convex outer surface, cords attachedto weights passing over rollers or pulleys in the frame of the window, the opposite end of said cord being attached to said stiles, window-sashes having a concave longitudinal groove in the edges thereof adapted to receive the convex portion of said stiles, fiat springs secured upon the ends of said stiles, having a concave portion thereof toward the frame of the window and amiddle spring having a concave portion thereof extending toward the frame of the sash in opposite direction to the end springs, pivot-pins passing through said stiles and said middle spring and connecting the vertically-movable stile and the frame of the sash, whereby said sash may be tilted in any position, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing Witnesses.

ARCIIIBALD Ii. BOLLES.
