SPECIFICATION forming part of Letters Patent No. 724,136, dated March 31, 1903.

Application filed June 21, 1902. Serial No. 112,706 (No model.)

T0 at whom it may concern:

Be it known that I, HENRY 0. SMITH, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Windows, of which the following is a full, clear, and exact'description, reference being had to the accompanying drawings, forming a part of this specification, in

explaining its nature. The invention relates to an improvement in windows, and essentially to the means by which a sash of normally closed vertical ex tension having its sides sufficiently secured within the interior facing of the frame to provide a weather-proof joint may be revolved to any degree of opening crosswise the frame without the removal of any part and upon the return of the sash to its normally closed position the recessing of its edges within the sides of the frame may be automatically reobtained and their weather-proof joint therewith restablished. The means for obtaining this adjustment, together with other improvements in the combination and organization of parts, may best be seen by reference to the drawings, Wherein- Figure 1 shows the sashes in elevation and broken away in part to show the pivotal construction of the upper sash. Fig. 2 shows the sashes in vertical cross-section. Fig. 3 shows a horizontal section through the upper sash. Fig. 4. is a horizontal cross-section through the stationary lower sash. Fi 5 shows in elevation a detail of construction of which mention will hereinafter be made.

Referring to the drawings, A is the windowframe. B, the upper sash, is represented in a vertically-extending closed position; but it is adapted to revolve to a more or less open position crosswise the frame, and C is the lower sash, which has a fixed. relation to the frame.

In order not to anticipate a detailed description of the pivotal connection of the upper sash, it is suficient to say at this point that the sides of the sash are provided with supporting-trunnions b, which have suitable bearings within the sides of the frame. Furthermore, the normal position of the sash is a closed one in-vertical extension, which result is obtained by overbalancing or weighting its under side.

In order to appreciate the scope of my invention, it is to be noted that the sash B, although it is a pivoting sash, makes a weatherproof fastening along its edges within theinterior facing of the frame. In other words, the edges of the sash extend into and along the frame,as though the sash was of vertical move ment. Itis therefore within the scope of my in vent-ion to provide means by which a sash thus extending and secured can be pivoted to an open position crosswise the frame, and not only this, but upon the closing of the sash the recessing of its edges within the sides of the frame may be automatically reobtained.

Primarily this result is made possible by the construction of the interior side facings to the frame, which have a groove or recessing along their entire vertical extension. This is best seen in Fig. 3 and indicated by the obtuse angular relationship of the sides or walls a. 0, In other respects the frame may be of any suitable construction. Extending into the grooves or recesses a are the movable sash extensions B, which rest along their edges flush up against the sides a a with their corresponding sides b These side extensions B are attached to the fixed body of the side rails to the sash, toward and from which they are movable telescopically, so that when extended out into the recessed interior of the frame the sash becomes locked against an outward or inward movement, but when withdrawn the sash may be taken out or reversedto a position crosswise the frame. It is also to be noted that the sides I) b of the telescopic extension, beveling out, as they do, and resting at an inclined angle within the grooved wall of the frame, are drawn or rather wear against these inclined frame sides a a when the sash is wrenc'hed at the top or bottom and the telescopic side extensions are forced back into the fixed body of the sash. This is especially true of the sash when pivoting. The trunnions b, which extend from the side exten sions, not only act as a center upon which the sash may turn, but extending as they do from the sash at or near the center of its length they facilitate the forcing of the side extensions against the edge of the frame in the fact that upon wrenching the top and bottom of the sash move in reverse directions and the cramping of the side extensions is primarily obtained at both ends. The trunnions are drawn in by the cramping back of the side extensions, which movementis taken advantage of, as will be described later. It is sufficient to say at this point that the trunnions upon their withdrawal do not lose their bearings within the sides of the frame.

The trunnions I), while they extend from and are movable with the side extensions, in point of fact extend through them from the castings b contained within their hollow shells and of which the trunnions form an integral part. The shape of their castings is preferably as represented. They are made of considerable body in order that they may amply support the trunnions and also of some length in order that they may reinforce the shells of the extension-pieces, and especially their beveled facings, as much as may be necessary. They comprise also the side plates b b which reinforce the sides of the extension-pieces.

The extension sides are retained in position so as to telescope in and out of the fixed body of the sash by means of the pins 6. The pins or bolts extend crosswise the fixed sash side and pin through the sides of the extension-pieces and also the reinforcing side plates 1') 19 In order that a lateral movement of the side extensions may be obtained, slots 11 are cut in theirsides and also through their reinforcements at the points where the pins b are inserted, so that practically the pins 1) not only support the extending sides, but serve also as guides upon which they maybe laterally projected, the slots 17 being commensurate with the extent of theirlateral movement.

Thus farI have described the means by which the extension sides maybe forced back into the fixed body of the sash upon its pivoting and the sash revolved to an open position crosswise the frame. I have also. arranged that the side pieces may be automatically drawn back into the grooved recessing of the frame side when the sash becomes closed in vertical extension and a weatherproof j oint established.

The trunnions b, it is to be observed, are contained within the sides of the frame by extending through the openings at. These openings are also cut through plates a which reinforce the interior of the frame in order that secure bearing for the trunnions may be obtained. The trunnions I) would naturally rest upon the undercut edges a of the openings a, and being of sufficient extension would be drawn in by the side extensions as they were pressed back by the contact of their v beveled edges with the side of the'frame upon wrenching open the sash. In order, however,

that these trunnions may be automatically drawn out when the sash becomes closed, and being drawn out may also draw out the edges of the side extensionsinto the recessed sides of the frame, I have extended from the ends of the respective trunnions heads 12 which have drawing edges b When the sashis in a closed vertical position, as is best shown in Fig. 1, these edges b are adapted to ride up and rest upon the beveled edges a of the studs a extending from the reinforcingplates (t and the relation of these parts is such that when this adjustmentis obtained the sash is lifted and the necks of the trunnions no longer bear upon the cut edges a of the frame and its reinforcing-plates, but at their headed ends they rest obliquely along their drawing edges 19 upon the studs a The result is therefore obtained that the extension side pieces of the sash are drawn out when they come in alinement with the grooved interior facing of the frame side, for the weight of the sash bearing down obliquely along the beveled edges 1)" of the trunnions upon the correspondinglybeveled edges of the studs will be sufiicient to draw them out. In other words, the studs a form wedges, which spread or press out the trunnions as their obliquely-beveled edges are forced down upon them by the weight of the sash and they in turn being connected with the telescopic side pieces draw them out into the frame sides. It is to be observed that the headed ends of the trunnions do not ride up upon the beveled edges of the studs until the window is closed or nearly closed. This is in order that no binding stress may be exerted upon the side pieces during the pivoting of the sash, but only upon its becoming approximately closed. Until then after the side extension-pieces have been telescoped in by their cramping against the sides of the frame, as before described, the trunnions rest upon the edges a of the frame, and the sash is free to pivot 0r revolve to any position crosswise the frame and without binding against its sides. This is best seen and the varying positions of the trunnions in their bearings may be better understood, perhaps, by reference to Fig. 5, where I have shown in dotted lines the relative positions of their headed ends, one corresponding with the closed position of the sash, with the headed end of the trunnion resting upon the stud a the other corresponding with an open position of the sash when the neck of the trunnion rests upon the edge a and the headed end of the trunnion is swung away from the stud, and in this connection it is to be observed that the headed end of the trunnion would swing away from its bearing upon the stud upon a very slight degree of opening of the sash.

In order that there may be an impossibility of the trunnions being drawn through the openings a, it may be seen by reference to Fig. 5 that the trunnion is practically locked IOC against withdrawal by the lateralprojecting section b which is extended back of and beyond the edge a of the openings. The trunnions may, however, be withdrawn by lifting the sash and then withdrawing them.

cially applicable to the grooved interior facing of the frame, which is so necessary to the adjustment of the revolving sash and which, as may be seen by reference to Fig. 4, extends the vertical length of the window. Theside rail comprises the sections a and d, formed by different foldings of their short vertical sides. The inner section comprises the interior side 0, which is secured to the edge of the frame by suitable bolts or screws.

This side is continued by the side 0 to form the interior glass-rest 0 which is turned to form a flange 0 which retains the edge of the glass. This side 0 is then extended back to the facing of the frame by the side 0 the edge 0" of which is then turned so that there is formed a vertically-extending pocket 0 In order that the side 0 may be attached to the side of the frame, clips 0 are cut from its edge 0 These connect with the frame. The section at comprises the exterior side d, which is suitably attached to the outer side of the frame, and the side (1 bentin to form the outer glass-rest by the side d which is continued in to fit into and along the pocket 0 of the interior section aforesaid. This construction is extremely simple and may readily be attached to any frame side as well as the one which I have hereinbefore described.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1.
