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,j ro forming a part of this specification, in ex.`

plaining its nature.

The invention relates to an improvement in.

metal window frames and sashes, and particularly to means whereby the window-sashes l may be combined with the frame to slide' therein and may also be so combined with it as to be turned in the frame Without being detached from the frame for the purpose ofl rendering both sides of the sash `accessible zo from the same place. I will now describe the invention inconnection with the drawings forming a part of this specification, wherein-- Figure l is a view, part in elevation and part in vertical section, of enough of a window-frame and window-sashes to illustrate the invention. Fig. 2 is a detail View, enlarged, representing a means for locking the sashes together. Fig. 3 is aviewin section 3o upon the dotted line 33 of Fig. 2. Fig. iis a view in horizontal section upon the dotted' line 4 4 of Fig. 2 and in plan of parts below said line. Fig. 5 is a view in horizontal sec`- tion upon the dotted line 5 5 of Fig. l. Fig. 6 is a view in horizontal sectionupon the d otted line 6 6 of Fig. 1. Fig. 7 is aview in horizontal section upon the dotted line 7 7 of Fig. l. Fig. 8 is a view of the parts in Fig 7, 'rep-` resenting them in a different position. Fig. 4o 9 is a view in elevation, representing a form:

of spring-holder to which reference will hereinafter be made. Figs. l0 and ll represent a modified construction ot' side extension and trunnions, Fig. lO being afvertical section on the line l0 10 of Fig. l1.

Referring to the drawings, the upper window-sash A and the lower Window-sash B slide in recesses in the sides of the Windowframe C. They are in part balanced by weights connected with them by chains, the 5o lower sash being enough heavier than its weights to close upon the release of holdingshoes, to be described, and the upper sash4 being enough lighter than its weights to be closed by them upon the release of correspending holding-shoes.

Any suitable form of frame may be employedl'which is provided with guiding-recesses of a character to receive the sashes and theirtrunnions. In Fig. 5 I have repre- 6c sented the frame as having recesses c and recesses c for the trunnions. In Figs. l0 and 11 the frameshown has the same provision, the diference beingthat the recess for the trunnion is as wide as the recess for the sash and in extension of it.

The sash that I prefer to use has extension sides movable toward and from the remainder of the sash into and out of recesses in the frame in which they normally are for the 7o usual sliding operation of the windows. These extensions provide means whereby the sashes may be placed in the window-frame and entirely removed therefrom Without making any. portion ofthe window-frame detachable. The extensions also slide upon the trunnions.

D represents the extensions, and E the trunnions. 4 The extensions are movable in relation to the main frame of the sash in any desired WayLand I have shown them in Figs. 5 8o and'9 as movable telescopically with relation thereto Without having endwise movement, while in Figs. l0 and Il a slight endwise movement is provided them. The first-named end d2 is contained in thegcavity ofthe, sashframe and is connected with the extension by an adjusting-screw d3, which permits of a variable relation between the bar or rod andl the extension. Each extension may have two or more of them, and each has a latch d* (see Fig. l) to engage the catch d5 on the sash when the extension has reached the limit of its outward movement. By moving them in one direction the extension is moved inward toward the remainder of the sash, and by moving them in the other direction the extension is moved into the recess in the frame. In Figs, l0 and l1 the extensions are represented as provided with inclined slots CF, through which cross-rods d8, attached to the fixed section of the sash-frame, extend. By sliding the extensions lengthwise the fixed section of the sash they will also be at the same time moved inward or outward withinclined edgewise movement. It will thus be noted that the sash extensions of Figs. l0 and 11 are moved lengthwise the window-sashes as well as toward and from them and that when withdrawn to free the sashes from the slides they extend below the bottom of the lower sash and above the top of the upper sash. Consequently when it is desired to reengage the sashes with the slides it is simply necessary to bring them in line with the slides and then move them to the bottom or top of the frame, as the case may be, when the ends of the extensions coming into contact with the bottom or top of the frame will be moved outward automatically into the slideways with a lateral drawing motion, and the engagement of the sashes with the frame will thus take place. The movement of the extension, however, does not cause the movement of the trunnions or pivots E. These trunnions extend through holes in the extension, which are slots where the extension has the construction of Figs. 10 and ll, and are rigidly secured to the fixed part of the Window-sash, I prefer to the part d of the sash, which forms the recess for receiving the edge of the glass, and I also prefer that the trunnion be shaped to straddle this part and be secured thereto by riveting or in any other desired way.

The outer ends of the pivots or trunnions tit the recesses in the frame which contain them and may be of any desired length, and I prefer that the pivots or trunnions carry or support the friction or holding shoes F, which by bearing against the window-frame serve to hold the sashes to any position to which they may be opened as against the tendency of the lower sash to close or of the weight to close the upper sash. The shoe has a flat end of about the width of the trunnion and to t the recess in which the trunnion slides. It is mounted upon the end of a rod f, extending into a longitudinal hole in the trunnion or pivot made to receive it, and itsinner end extends into a slotf' across the pivot or trunnion. It is frictionally held against the window-frame by the spring-rod f2, contained in the cavity ot' the window-sash, and provided with the bent end f3, where it is united by fusible solder to the window-sash near an opening therein, so that heat from without the sash may at once reach it. The rod f2 is held in position to obtain a bearing against the end of the holding-rod by the clip f3. This clip is held in adjustable position by means of the boltf4, so that the clip, and so the rod f2 held thereby, may be moved laterally and its tension upon the end ot the holding-rodf varied at will. This result is secured by providing the clip with a threaded hole, as may be obtained from the txed nutf5, into which screws the boltf4, accessible from without the sash, but which by its headed end f, contained in the blockf7, is so held to the side of the sash that the bolt may be turned by suitable means, but prevented from being turned in and out. The result is that the clip moves back and forth upon the boltf'4, and so produces a lateral adjust-ment of the rod f2, resulting in an increased or diminished tensional bearing upon the end of the holding-rod f, supporting the friction bearingshoe.

As may be seen from Fig. 9, the rod f3 has an oifset at the pointfs, so that the upper section of the rod which bears against the holding-rod is away from the center of the lower section of the rod attached to the sash and passing through the clip]L74 as a center. Upon a release of the rod where itis soldered to the sash atff, as in case of lire, the rod turns sufficiently7 in the clipf4 as a center that its upper section swings away from the end of the holding-rod, and the tension resultingly being removed from the friction bearing-shoe the window, being overbalanced, as before described, automatically closes.

To place the sashes in the window-frame, their extensions are moved inward against the fixed sections, leaving exposed the ends of the trunnions or pivots and the friction bearing-shoes issuing therefrom and in their engaging position. The sash cords or chains F' are then attached to the ends of the trun nions, as may be seen by reference to the drawings. The trunnion or pivot and its friction bearing-shoe on one side of the sash is then placed in its recess in the frame, the sash turned to a horizontal position and lifted on the said trunnion or pivot as a center until the disengaged trunnion may clear the frame and enter its recess on the other side of the frame, when the sash is turned in a horizontal position and then turned t-o a vertical position, which will bring its extensions in line with their holding-recesses in the frame. The extensions are then moved outward into them, and the sash'is free to be moved vertically in the frame. It is to be observed that after the two trunnions have entered their recesses and the friction-shoes brought to bear against the side of the frame the sash will be sustained and its pivoting in being brought from a horizontal to a Vertical position easily obtained. The attachment of the sash-chains to the ends of the trunnions and the method before described IOD IOS

IIO

for increasing the tension upon the friction bearing-shoes are also to be noted as facilitating this adjustment.

To turn the sash in the frame, it is simply necessary to move inward the extensions. The friction bearing-shoes will remain in their bearing against the sides of the frame and the ends of the trunnions to which are attached the sash-chains left exposed. The sash may then be turned to expose either surface to the inside of the window without becoming disengaged 'from the frame and without engaging with the sash-chains or interfering with the stress of the shoes upon the frame, which prevents the sash from operating the sash-weights or the sash-weights operating the sash while it is thus being manipulated.

It will be understood from the foregoing that the friction bearing-shoes are automatically released by heat and that when so released the sashes automatically close. They are automatically locked when closed by the latch G, which is pivoted to the upper-sash frame to engage by gravity a shoulder or catch g upon the lower sash when it has been moved by it. (See Fig. This latch is described in another application of even date and is not`claimed herein.

The sashes have weather-stops provided in their meeting-rails by means of the overlapping plate h, secured to the meeting-rail H of the lower sash, and the overlapping plate h', secured to the meeting-rail H' of the upper sash. These plates each provide a recess into which the opposing plate may enter, and thus provide an verlapping weather-lock, doing away with any necessity for a wedging of the rails together and the use of a wedge in connection with the sash-lock, as described in my said application. The plate h is united to the plate h2 and the meeting-rail H by extending along its side underneath it, then upward into the glass-retaining recess, form; ing one wall 0f it, and then downward over an upturned flange of the said plate h2. This construction serves also to stiffen and strengthen the ralH. 'Ihe overlapping plate h is formed from extensions of the plates h3 h4 of the meeting-rail H', which are bent outward together, then upward together, one of them being made sufficiently long to be bent downward over the edge of the other.

The movable extensions D of the windowsash may be combined with the rigid part of the sash-frame in any desired way to be movable toward and from it for the purpose of widening it. The form of construction which I prefer to employ is represented in Figs.l 10

and llfwhere the extension D on one side of the sash-frame is represented as made from one piece of sheet metal so bent as to provide,

metal formed to provide the groove d for the glass and the sides (i12 clls and the outer faces dm 15 at each side of the recess or slideway in the window-frame, the sections d10 engaging the movable extension, which forms the Walls of a space between the sides and which space is of the width of the recess or slideway in the window-frame. The sections d10 are wide and the recesses df are deep and the space within'the sash-frame beyond the extensions of sulcient depthv to permit the extension D to be moved into the sash without disengaging the parts, the 'extension sliding upon the sections d10 and the movement being sufficient to bring the outer edge ofthe ex# tension in line with the outer faces d (115. The parts of the extension forming the recesses d10 are slotted to permit' the movement of the extension with respect to the cross-rods d8, and these slots are inclined where it is desired to effect the closing or opening of the extension by its own movement lengthwise the Window-sash.' Each extension D also has in its outer face a recess d1 for receiving la part of the trunnion and shoe (see Fig. 11)

and also to provide room for the sash-holding cord or chain which engages the trunnion.

To increase the frictional surface of the brake-shoe, it may be slightly beveled, as repi resented in Fig. l1, and the surface of the window-frame against whichit bears may be correspondingly shaped. Y

In Figs. 5, 6, 7, and 8 the extension E and the sash-rail are somewhat differently constructed, the extension being reinforced upon its sides by portions of the plate formingit, which are bent backward directly, entering deep recesses in the sash-rail formed by inward and outward extending parts of the rail, the inward-extending part serving to reinforce the sides of the rail. I do not, however, confine myself to any particular way of attaching the side extensions to the sash-rails, so that they may be moved bodily toward and from the sash-rails.

In use the window-sashes are arranged to close in the ordinary way and,'if open, in case of ire in their vicinity releasing their thermostatic holders, close automatically. VThe sash'es are placed in their window-frames as I have already described.

It is to be observed that the construction is especially advantageous in the washing or cleaning of the windows, in that the outer surface of the window may be cleaned from inside the room, and this Without the removal of any part. This maybe done simply'by moving inward the extensions, when the sash may be revolved to any position of advantage. During this manipulation the sash is held to the side of the frame by the friction bearingshoes, upon the holding-rods of'l whichv the trunnions turn for a center. Where the thermos-tatie release is em ployed,the,frictionbearing-shoes will still be held to the frame by sufficient friction to hold' the sash, and this by a means which in no way interferes with IOO IIO

the normal bearing of the shoes or the Inanipulation of the sash. The sashes are restored to their original positions in the window-frame by being moved to a vertical position with respect thereto and by moving out the extensions, as before explained.
