1 Claim.

The present invention relates to windows and more particularly to a window embodying novel means whereby the upper and lower sashes are adapted to be mounted in a window frame for vertical sliding movement therein and also for forward swinging movement relative thereto.

One of the objects of'the invention is to provide a simplified construction to accomplish the above objects andalso to permit the sashes to be quickly removed from the window frame when desired.

Still a further aim is to construct a sash which is both vertically slidable and capable of being swung forwardly out of the frame, said 'sash embodying means which functions as a pivot, the latter designed so that it may serve to disconnect the sash at one point for removal of the latter from the window frame.

The above and other aims and objects will gobe apparent from the detailed description hereinafter appearing when taken in conjunction with theappended drawings forming part hereof and to which reference is now made and in which: i

Fig. 1 is a frontelevational view of a standard window frame having the novel sash construction mounted therein;

Fig. 2 is a sectional View taken on line 2-2 of Fig. 1; I

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a view similar to Fig. 2, with the sashes removed, showing the groove for receiving a rod carrying metallic weather strips;

Fig. 5 is a front elevational view of the weather stripping rod and upper and lower slidable sash bars associated therewith;

Fig. 6 is a side elevational view of the structure of Fig. 5;

Fi 7 is a detail vertical sectional view centrally through the top portion of one of the sash bars;

Fig. 8 is a sectional View taken on the line 88 of Fig. 5;

Fig. 9 is a detail sectional view showing a latch for connecting a sash and one of its slidable bars;

Fig. 10 is a detail sectional View of a pivot fitting and means whereby the sash may be disconnected from one of its slidable bars.

Referring now to Fig. 1 of the drawings, it will be seen that the window constituting the present invention comprises a frame generally designated as I, said frame including a stool 2, 55 vertical side members 4 and 5, and a top cross member 5. Each vertical side member has its inner surface stepped (see Fig. 3), to provide vertical channels 1, Sand a groove 9, which receives a removable wooden bar I0 which has upper and lower metallic weather strips II and I2 secured thereto on opposed side faces thereof as by nails I3 or the like. The window frame just described is of conventional or standard construction with the exception that the removable wooden bar I0 is normally permanently fixed on the inner surface of the frame and provides a dividing guide forming channels I and 8 in which the sashes move vertically. It will be understood that each of the opposed inner faces of the frame is of identical construction; also that the sashes to be hereinafer described are of like construction at their vertical side edges which cooperate with the channels and Wooden bar If].

The channels I and 8 are each provided at the upper ends thereof with pulleys I4 and I5 on which are mounted cables I6 and I1 secured at one end to sash' weight (not shown), and, within the frame, cable i6 is detachably secured to a removable, slidable, upper, sash bar I8 and cable I I to a similar lower bar I9. An upper sash 20 is pivotally and removably secured to sash bar I8 and a lower sash M is similarly secured to sash bar I9, in a manner to be shortly described.

Referring for the moment to Figures 5, 6 and 8 and to sash bars I8 and I9, it will be noted that bar I8 is substantially square in cross section and is provided at one corner thereof with a vertical groove or slot 22 which receives the metallic strip 'I I. Thus after wooden guide bar I0 is fixed in groove 9, and bar I8 mounted so that groove 22 receives strip I I, the latter will function to guide bar 53 in its vertical sliding movement within channel I of the window frame. The top of bar 18 is provided with a groove 23 within which a knotted end 24 of cable I6 is detachably received in a manner well known in the art. A metallic pivot member 25 secured to the top of bar I8 has a vertical portion 26 extending into groove 23, the horizontal section El contacting the top of bar I8, and an inner vertical portion 28 which terminates in a hook 29. Sections 26 and 28 are provided with aligned apertures-30 (see Fig. 10) for a purpose to be referred to later.

A side face of bar 58 is cut away as at 3| to receive a pair of arms 32, 33 pivoted to each other at 34, and to bar I8 within the cut-away portion ill, at 35. The bottom face 36 of bar I8 is provided with a slit 3'! within which is pivoted as at 38, a latch bar 39. a

By reference to Figs. 3, 9 and 10 it will be noted that one end of the upper surface of sash 20 is hollowed out to form an elongated groove 4|. A pivot member 42 has a horizontal plate portion 43 and a vertical section 44 which is re- 5 ceived within hook 29 of cooperating pivot member 25. A slidable pin 45 constitutes a pivot for members 25 and 42. However, when pin 45 is moved to the right, as seen in Fig. 10, within groove 4|, said pin will be withdrawn from aperture 30 in bar l8 into which it extends, so that sash 2|] may be disconnected therefromat this point. The lower face of sash at one end thereof is provided with a slit 46 for receiving latch bar 39 so that the sash will be connected to 5 bar 8. When the latch is moved downwardly about pivot 38 the sash and. its bar are disconnected at this point. Arm 32 is provided with an aperture 32, at one end thereof (Fig. 5), for detachable connection to a removable screw 41 20 carried on the inner face of sash 20. It is desired to point out that each of the inner faces of sashes 20 and 2| are of identical construction; that bars l8 and I9 are similar only in that they are mirror images of each other; that sash 2| has a pair of pivot members at its opposed faces as at 50, 5|; that sash 2| has two latch members, as at 60, 6|. In other words there are two bars |8 for sash 20; two bars IQ for sash 2|, and that the structures are duplicated adjacent each edge of the respective sashes.

Mode of operation In the position of the sashes shown in Fig. 1,

they may be each moved vertically up and down 30 in a normal manner, bars I8 and I9 being guided in channels I and 8 by bar |0. Should it now be desired to swing the sash forwardly, it merely becomes necessary to raise same a trifle above stool 2, then to insert a hand within a finger hold 46' (Fig. 9) to grasp latch 39 and swing same downwardly about pivot 38. This is done at the opposed ends of the sash and the latter may now be pulled forwardly, pivoting on its pivot pins 45. The sash is held in its forwardly swung position by pivot arms 32, 33, as shown in Fig. 2. Now should it be further desired to remove a sash or sashes, pivot pins are moved inwardly toward each other out of aperture 30. By means of a screw driver or the like, screws 4'! are unscrewed to pass through aperture 32' in arm 32. After this has been done each of the sashes becomes separable from the respective bars |8 or IS. The latter can then be removed by withdrawing same so that metallic strips H and I2 no longer fit within groove 22 of said bars. Finally bar H], which carries metallic strips II and I2, may be withdrawn from its groove 9.

It will thus be seen that there has been provided a novel window structure which is readily disassembled, and Well adapted to perform its intended functions. Standard window frames may be easily modified to accommodate the novel sash construction of this invention. Further, when the sashes, the slidable sash bars I8 and i9, and weather strip bar are removed, the interior of the frame and the various parts of the window proper may be readily painted or decorated.

While the invention has been described in somewhat great detail, it will be apprecated that various changes and modifications thereof can be made and it is my intention to be limited in this respect only as may be necessary by the scope of the claim hereto appended.

I claim:-

In a window, a frame having each inner face provided with a vertical groove, a removable bar having a metallic strip secured thereto mounted in said groove, a slidable sash bar having a longitudinal slot, said metallic strip extending into said slot to guide said sash bar, a sash, unitary means pivotally and releasably connecting the upper edge of the sash to the top of said sash bar, means pivotally and releasably connecting an intermediate portion of the sash bar to the sash, and means releasably securing the bottom of the sash bar to the sash.
