METALLIC WINDOW FRAME AND SASH.

SPECIFICATION forming part of Letters Patent No. 724,133, dated March 31, 1903.

Application filed January 2, 1902. Serial No. 88,226. (No model.)

To all whom it may concern:

Be it known that I, HENRY COLLIER SMITH, a citizen of the United States, and a resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Metallic Window Frames and Sashes, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forminga part ofthis specification, in explaining its nature.

The invention relates to an improvement in the construction and adjustment of windows having a fixed lower sash and a swinging upper sash; and some of the objects of the invention are to provide improved means for the mounting and adjustmentoftheswinging sash, especially that a weatherproof fastening may be secured. In the construction of the fixed lower sash it is desired that all unnecessary detail in construction may be eliminated, that the area of the glass panel may be increased, and that the same may be easily inserted and retained through the use of detachable sections.

With these and other objects in view the invention consists substantially in the construction hereinafter more fully described in the specification, and illustratedin the drawings, in which- Figure 1 is a view in elevation of a portion of a metallic window and of two window-sashes containing my invention. Fig. 2 is a view in vertical section upon the dotted line 2 2 of Fig. 1. Fig. 3 is a view in vertical section upon the dotted line 3 3 of Fig. 2 and in eletion of parts back of said line. Fig. 4is a detail view in horizontal section upon the dotted line 4 4 of Fig. 1, showing the sash in closed position. Fig. 5 is a view of the same parts representing the sash as swungopen. Fig. 6 is an enlarged cross-sectional view through the fixed sash, showing especially the retaining-caps for the fixed glass pane. Fig. 7 is a View in horizontal section upon the dotted line 7 7 of Fig. 1.

In the drawings, A is the lower glass light or lights, represented as occupying afixed re-. lation to the window-frame B, and Cis a window-sash which is shown as having a pivoted relation to the frameB, so as to swing from a vertical closed position to a more or less' inclined open position crosswise the frame. This sash isrepresented in its closed position in Fig. l and as open in Figs. 2 and 5. It is attached to the frame by pivots, one lettered 0 being shown, which rest in open hearings or sockets b, formed in brackets attached to the frame, the bracket shown being lettered b. The pivots are carried by plates vertically adjustable upon the window-sash, preferably by means of slots in the sash-rail and screws or bolts passing through them. The plate shown is lettered c, the slots in it 0 and the screws 0 This construction permits the sash to be placed in the frame and removed from it without the removal of any parts by simply opening the sash and moving it upward to disengage the pivots from the bearings. It also permits the sash to be adjusted in its opening in the frame 'and with respect to its bearings by changing or adjusting the pivot-" plates upon it. The sash is represented as so attached to the frame as to cause its lower part beneath the points of attachment to be heavier than its upper part, and thus serve to automatically close it and maintain it closed. It is locked, preferably automatically, in its closed position bya spring-actuated latch 0 carried by the upper bar of the sash, and a catch 0 in the top of the window-frame. It is represented as held open by a cord or chain 0 preferably attached to the latch 0 that it may be used for also withdrawing the latch from the catch preparatory to the movement of the sash, and this cord or chain at its lower end has a loop, hook, or other means a for detachably connecting it with the stationary hook or holder 0 The loop 0 may itself be destruotible by heat, or any other portion of the cord or chain may be made to be so destructible. The holder 0 is also secured, preferably, to the frame or lower sill by means dostructible by heat and preferably by heat upon the exterior of the window frame and sash. As it is desirable that this engaging and holding end should be upon the inside of the window-frame, I have represented it as having an extension 0 through a hole 0 on the inside of the sash-frame and beneath the glass of the frame to a point upon the outside of the frame, passing through the hole (1 therein, where its end is united to the sashframe by means destructible by heat, preferably fusible solder, the said means being thus placed in an exposed position upon the outside of the sashes at or near the sill of the window-frame. It will thus be seen that the device for holding the sash open has two places at which it maybe automatically separated or detached from its holder to permit the window-sash to automatically close. One is inside the sash and would be operated by undue heat within the room or apartment within the window and the other by the presence of undue heat upon the outside of the window. As the extension 0 is curved as represented, it may readily be withdrawn from the frame by the window-sash in case the connection therewith becomes destroyed.

I have represented in Fig. 3 the extension 0 of the holder as being covered in part by a sheet-metal housing or cap 0 to protect it from the cement or substance with which the sill-cavity is filled, attached to the frame of the lower window-sash.

The window-frame B has a construction which permits it to be readily adapted for use in receiving and holding any type of pivoted or hinged window-sash either in connection with or in a fixed window-sash or light of glass, and in this connection I would say that I do not confine myself to the manner of pivoting or hinging a movable window-sash lo the frame or to the direction in which it shall turn with respect to the frame in opening and closing a window; neither do I confine myself to the places in the window-frame where it is located. The windowframe has sheet-metal side sections, one of which (lettered Z2 is shown. These side sections are connected at the top and bottom by suitable sheet-metal connections, and each one is preferably made of a single plate of fiat metal shaped to provide the stiffened corners b If, the sides 11 I) and the vertical face b bounding the window-opening and in which is the vertical recess or groove b The face preferably is of about the width of the thickness of the sash-frame, and at each side of it there is a plain surface b 1), against whichportions of glass-retaining caps may bear and be secured and which may end in angular shoulders Z) D extending outward and forming an abutment to conceal and cover the raw edges of the glass-retaining caps. The recess or groove b is preferably midway the sides 1) b Itspurpose is. to provide means for the locating and for the holding or for assisting in the holding of the parts known as glassretaining caps, forming a part of the fixed or stationary window for holding the glass therein, of which I shall hereinafter make mention, and also portions of the Weatherstops which are used in conjunction with other weather-stops attached to the pivoted or hinged window-sash, as may be seen by the sash.

comparing Fig. 4 with Fig. 6. The grooves b are so located to permit them to be used for both purposes and wherever it may be desired in the height of the window to locate stationary glass lights or movable sashes of the character described, or either, and also to permit the reversal of the weather-stops necessary between pivoted sashes and windowframe, to be hereinafter described.

E and E, Figs. 4, 5, and 7, represent the weather-stops for the movable window-sash and the section of the window-framein which it moves. The weather-stop E is attached to the frame and the weather-stop E to the sash. One is bent to form a recess or groove, into which the other closes, and where the sash is pivoted to the frame the groove at one side of the pivot will be upon the stops attached to the frame to open the other side of the pivot to the stops attached to the sash in order that the sash may be turned. In Fig. '7 the weather-stop E is represented as provided with the groove or recess 6. It is formed by bending backward a part of the metal of the stop and so as to present its opening e'toward The weather-stop also has the section e which enters the groove b and the portion e which lies along the face I) of the frame and is attached thereto by riveting or in any other desired way. The weather-stop E is attached to the corner of the frame of the sash B. It has the section 6 projecting outwardly from the corner to enter the recess 6 when the sash is closed, and the section 6'', which is contained in the recess or groove e of the sash-frame, which also holds a corresponding part of the piece e forming the sash-plate edge, the groove or recess being formed from the piece a of the sash-frame which provides the sides, inner edge, and glass-receiving groove and which is bent backward upon itself at the corner and then outward again to form the said recess or groove, the parts being secured together by pressure, riveting, or solder. It is to be observed that these weather-stops, however they may be constructed, are placed on the outside corner or inside corner of the sash, depending as they lie above or below the pivot on which the sash swings-in other words, exactly in reverse positionthat the top section of the sash may swing outward into a weather-stop and the bottom section inward, the plateholding recess 12 being especially adapted to facilitate such adjustment.

Particularly important in a window of this kind is the construction of the means for the retention of the fixed glass light, especially that the glass may readily be secured to the frame by the use of removable sections, for as the glass is fixed all unnecessary parts which might go to make uparemovable sash are eliminated and the glass built, as it were, into the frame, thus necessitating a radical change in the detail of construction.

In Fig. 2 are seen the top and bottom settings to the glass. Instead of a bottom rail the glass is lowered directly into a groove B in the window frame or sill. The top setting consists of the rail D, connecting the two sides of thewindow-frame. This rail may be made in sections, as seen 'in Fig. 2, or of a single piece of sheet metal. The rail is shaped especially to provide the projecting section d and beveled facing cl, against which thepivoting-sash may close, and to provide also the holding-flanges d d for the retention of the upper edge of the fixed glass light and which, in effect, forms a bottomless grooved opening into the cavity of the bar. As for the side sections stiles are dispensed with and the glass set, as it were, into the frame, the width of the glass being determined by the distance between the sides of the frame, sufficient space only remaining to permit an easy insertion. Thatthe glass may be retained in place along the sides to the frame I have the detachable and attachable side sections H and L. The side section H is shaped or formed to provide first the flange h, which is secured to the side 11 of the frame by suitable bolts or screws. The piece also has the surfaces It and it formed to provide the face 71 which acts as an outer stop or flange against which the glass may hear. The section also has the sideh offering an end-retaining surface to the glass, While the flange-piece h is adapted to enter the recess 11 formed in the side of the frame. It is to be observed that as this section H is constructed it becomes locked to the side of the frame when the glass is inserted. In other words, in order to detach it the glass must first be taken out of its setting. Section L consists of the flange l, detachably secured to the side h of the frame. The section also has the surfaces Z 1 formed to provide the retaining-face l to the glass and also acts as a flange to enter the recess 19 so securely fixing the section. This construction permits the glass pane to be placed in the windowframe, with the cross-bar B and sill in position or fixed to the rest of the frame, but of course before the glass-retaining caps H and L have been placed, it being simply necessary to lift the pane sufticiently between the flanges d 11 into the cavity B to permit its lower edge to be brought into line with the groove B. A downward movement of the pane will then enter it in this groove, While its upper edge will still be retained between the flanges aforesaid. The retaining-caps H are fastened to the frame before the glass is placed in position, and the retaining-caps L are then secured in place to the frame, the recess 17 being so located and the retainingcaps L being so shaped to permit the caps to be moved toward the faces of the frame and their sections 12 to be within the grooves and their sectionsZ attached to the sides of the frame.

The advantages of the construction are apparent.

In connection with the fixed glass light it is to be understood that this may be regarded as being set in a fixed sash, the sill, upper cross-bar, and detachable side sections acting as a sash for the setting and retention of the glass, or the glass light may be regarded'as being set right into the frame and the de-' tachable side sections acting as a detachable part of the frame for the setting and re'ten-* tion of the glass. The latter observation would perhaps be the more preferable.

Having thus fully described my invention,
