This invention has to do with certain improvements in windows and the like. The features of the invention are particularly applicable to the construction and operation of 5 windows of that type in which the sash are mounted for Vvertical movement in the casing. -Y i The'main object of the invention is to provide a window construction which is so arranged that the sash thereof can beV swungV or turned out into the room in order to make them accessible for cleaning or similar operations. In this connection, it is particularly an object to provide an arrangement such that both the upper and lower sash Vcan be thus turned or swung out into the room when in the lowered position, in which position they are most easily accessible for cleaning and similar opera-tions. In this Vconnection 2U it is noted that it is customary to place the upper sash at the outside face of the lower sash so that during the raising and lowering operations the upper sash passes or occupies a position at the outside face of thelower sash. Furthermore, it is customary to provide for a certain amount of lap, or overlyv ing face to face engagement of the top rail of the lower sash and the bottom rail of the top sash when the sash are in their normal closed position. This overlap insures such an engagement between the adjoining sash as to insure a weather tight or air tight con tact between the parts.

It will be noted, in connection with the foregoing circumstance, that upon raising the lower sash to the raised position as ordinarily established heretofore, the lower edge of said sash does not rise high enough to allow the upper edge of the upper sash toV pass beneath i' it when the upper sash is fully lowered.Y In

other words, according to previous construc-V tions the two sash will interfere to such an extent that it is not possible to 'swing the upper sash inwardly by a simple pivoting or hinging operation. i l s One of the features of the presentv invention relates to the provision of a construction :n which there is provided an eXtra amount of head room or space above and in line with rne lower sash so that when said sash is raised Vto the provision of an improved construcit may bel moved up an eXtra distance into i said head room so as to raise its lower edge high enough to permity the top edge' lof the upper sashl to VVswing beneath Vitwhen the upper sash ismoved toits lowermost posi-v tion. 1 ff Another feature of the inventionrelates to the provision of a very simple Vand strong construction for 'supporting both of the sash and permitting them to slide readily, while at the same time establishing Vthe necessary hinging relationship.

Another feature of the invention relates to r the provision of an improved construction of stop strip, which can be readily slid up out of the way in order to permit the sash to be swung out into the room under th proper conditions. Y

Another feature of the invention relates tion of parting strip which can `be readily removed in order to allow the Lipper sash to be swung out into the room when it is lowered to the proper position. 1

Another feature of the invention relates to the provision of an improved construction embodying the slide and the hinge connection for'l the sash, said slide being so `arranged as to'also malreproper provision for connection of the counter balance weight thereto.

n vOther objects and uses of the invention willv appear from a detailed description of the same, which consists in the features of construction and combinations of parts herein. after described and claimed.

Figure shows a vertical section on the line 5-5 of Figure 1, looking in the direction of the arrows, and it shows the additional head room provided for the lower sash, the lower sash being shown in`- lowered position by full lines and in raised position by means of dotted lines Figure 6 shows an edge view looking at the right-hand edge of Figure 1; l

Figure 7 shows an edge view looking at the left hand edge of Figure 1 5 Figure 8 shows a fragmentary section on the line 8 8 of Figure 1, looking in the direction of the arrows; and

Figure 9 shows a fragmentary viewsimilar tothat of Figure 3, but illustrating a modi- `fiedtype of constructionof the slide.

In the different views Figures 3, 4, 8, and 9,-are on enlarged scale as compared to the remaining figures.

'The construction illustrated includes a casing having the side portions 10 and 11, the head 12, and the sill portion 13. The construction also includes the upper and lower. sash 14 and 15 respectively. For purposes of convenience the sash as well as the casing are shown as being made principally of wood construction although manifestly sheet metal or' other suitable construetions might be used.

As shown especially in Figure 5, the lower rail 16 of the upper sash 14 and the upper rail 17 of the lowersash 15 overlap when the sash are in the closed window position, which is illustrated in Figure 5. vAs onefeature of iny invention, I provide a slotted opening 18 in the head portion 12 and above and in line with the lower sash l5 so that said lower sash can be raised an extra distance as shown by the dotted lines in Figure 5. Preferably a false cap or head 19 is placed over the slotted opening 18 but sufficiently elevated to permit the necessaryfreedoin ofmovement of the lower sash intothe full dotted line position. This movement is sufficient to permit the sash 14v to swing beneath the fully raised lowerl sash as will be evident froniin'spection of Figure 5. In that ligure, the dotted line 20 indicates the bottom edge of the fully raised lowersash and the dotted line 21 indicates the-top edge of the fully lowered upper sash and comparison indicates that Vthe sash ,can pass as already explained.

Examination of Figures 2 and 4 shows that there is provided a slide plate 22 for the lower sash. This vslide plate passes through a slotted opening 23 in one side of the window casing, `which slotted opening may be extended the full height of the casing if desired. lThe inner edge 24 of this slide plate is hooked as shown in Figure 4 and is thus adapted tofengage the tongue portion of an angle-bar 25 which extends vertically inside of the casing and is secured to the casing in suitable manner as by means of the screws indicated in Figure 4.

The edge portion of the slide 22 slightly overlies the edge of the lower sash 15 to which it is hingedly connected as shown at 26. The result is that the lower sash can be turned out into the room as shown by the dotted line position of Figure 4. Preferably a-n angle bar 27 is secured to the slide adjacent to the Yface of the casing as shown in vFigure 4, so'as to assist in guiding the parts `during their: sliding movement and also to make the construction more air-tight.

The strip 28 is secured tothe face of the casing in fiont of the hinged edge vof the lowersash 15. As clearly shownin Figure 4 iii particular, the face 29 of the strip 28 is eut back or 'relieved so as to provide the necessary clearance to allow the upper sash to swing out into the room as will be presently explained.' y

Due to the fact that the slide plate 22 extends for substantially the full height or verticaldimension of the lower sash,.a very strong support is provided for the lower sash so as to take care' of the severe tendency to rock or rotate the slide 22 about a horizontal axis extending at right angles to said slide.

A'Ihereis also provided a slide plate 3() for the upper sash 14, said plate 30 extending through aslotted Yopening 31 in the other side of the casing; and the inner edge 32 of the slide plate 30 is bent or hooked over to engage an angle bracket 33 secured to the insideportion of the casing in manner similar to that already explained with re spect to the lower sash. Likewise, the slide plate 30 extends through the casing and slightly overlies the edge of the upper sash 14 to which it is hingedly connected by the hinge connection 34.

Strips 35 and-36 are permanently secured to the sides of the casing inposition to guide the ,outside face edges of the upper sash 14.

The other edge of the lower sash 15 is guided by a specially constructed strip, the detailsof which are best shown in Figures 3, 5, and 8. `Ihis strip includes a slidable section. 37 of vertical dimension somewhat greater tlia-n that of the lower sash. Said strip 37 is provided with angle strips 38 and 39, secured to its inside edge corners. 'Ihe central portion of the backface of the strip 37 is cut away or recessed vertically to receive a plate 40. vSaid plate is secured to the face of the'casing by means for screws and in proper spaced relationship by Vmeans of a spacer strip 41. The result is that the angle plates 38 and 39 hook behind and engage the plate 40 which thus guides the strip 37 in its vertical movements.

f Thek strip 40 extends the full height of the Preferably a channel-shaped boX strip 42 A is secured to the face of the casing above the position of the lower sash so that the strip 37 will run up into said strip 42 and thus permit the two parts to be telescoped together. This will establish a finished appearance tor the structure and at the same time assist in guiding the sliding movements of the strip 37.

There is a parting strip 43 permanently secured to the casing between the edges of the upper and lower sash at the hinged edge ot the upper sash as shown in Figure 3. There is a removable parting strip 44 between the upper and lower sash at the position of the swinging edge of the upper sash 14 (see Figure 4). This removable parting strip 44 is carried by a plate 45 which can be slid back beneath another plate 46 which has its upper and lower edges permanently connected to the casing. Upon swinging the lower sash out into the room or upon raising the lower sash to the full extent, this parting strip 44 can be slid or pulled out into the room as will be clearly evident from examination of Figure 4.

It will be evident from the dotted line 47 in Figure 4 that the swinging edge of the upper sash can pass the strip 28 by reason of the fact that the face 29 of said strip is cut back or relieved as shown in Figure 4.

Each of the slides 22 and 30 is provided with a bracket 48 in which there is connected a cord 49 passing up over a. pulley 50 in the upper portion ot' the casing and `carrying a counter-weight 51 at its lower end, all of which is best illustrated in Figures 6 and 7.

In the modified construction of Figure 9, the slide plate 52 is shown of angle form instead of straight as in Figures 3 and 4 in particular. Vhen using this angle form the slot 53 in the casing may be offset from the position of the hinge 54. Also, when this construction is used it is possible to provide a weather strip 55 which extends forwardly from a positionbeneath the casing strip 56 to overlie the central angular portion of the slide, occupying a position between said angular portion and the edge of the sash. This will materially improve the weather resisting qualities of the structure.

Vhile I have herein shown and described only certain improvements of the features of my present invention, still I do not intend to limit myself thereto except as I may do so in the claims.

I claim:

1. In a window construction, the combination of a casing, upper and lower sash therefor, and means for individually supporting said sash to permit them to slide freely up and down independently of each other, together with removable parting and guide strips 1ocated at opposite sides of the' casing, said removable parting strip including a parting member, together with a relatively thin plate to which said parting member is connected, said plate normally lying in face contact with the face of one side of the casing and between Y the casing and the edge of the upper sash, and the slidable parting strip including telescoping members, the larger of which is permanentlysecured to the upper portion of the side of the casing, and the lower Vof which is slidably connected to said side of the casing and in position to telescope upwardly into the rst mentioned section,substantially as described.

2. In a window construction, the combination of a casing, upper and lower sash slidably mounted therein, and guide strips for said sash, at least one of said guide strips being movable from a working position to a non-working position, said guide strip includf the non-working described.
