WINDOW CONSTRUCTION.

Application led May 5,-y 1922.

lowing is a full, clear, and exact description y thereof, reference being had to the accompanying drawings, and to the letters of refer-v ence marked thereon, which form apart of this specification.

This invention relates to improvements in window construction and consists of the mat'- ters hereinafter described and more particularly pointed out in the appended claims:

One of the objects of the present inventioii is to improve the construction and operation of that kind of window, wherein the sash is not only capable of a vertical sliding movement in the frame but is also capable of an inward swinging movement with respect thereto.

A further object of the invention is to provide novel means for locking the sash against a vertical Sliding movement after it has been swung inward y about the bottom end as a pivot.

The advantages of the invention will more fully appear as I proceed with my specification.

Figure 10 is a view similar to Fig. 9 with the parts in a changed relation.

Figure 11 is a perspective view of a braking block embodied in my improved window construction.

Figure 12 is a perspective view of a sash bracket plate embodied in in improved window construction which will be more fully referred to later.

Referring now in detail to that embodi ment of the invention illustrated in the accompanying drawings, 15 indicates as a whole, a window frame and 16 and 17 indicate the top and bottom sash associated herewith. The window frame includes upright Side members 18, a top lintel 19 and a sill 20, all of well known construction. Fixed to the opposed faces of the side` members are the inner and outer moulding strips 21 22 which are spaced eqiiidistant apart from the parting strip 23 to provide inner and outer sashgrooves 24-25 respectively, for the bottom and top sash 17 and 16. 26-26 indicate sheet metal channel strips which fit snugly in and extend the full length of the outer sash` grooves 25. Said channel strips each include outer and inner flanges 27 28 which engage in grooves 16* 17 inthe outer surfaces of the upright side members,

l16b and 17b of the top and bottom sash 16 and 17. (See Fig. 3.)

The Side'members 16l 17b of the sash carry threaded bushings 30 31 to receive coacting locking pins 32-33 which may be threaded through said bushings to engage the side members of the frame, to lock the sash against both a vertical sliding and an inward swinging movement as will later appear. In the case of the pins 32 associated ,with the top Sash, the channel stiips 26 are provided with suitable holes or apertures through which said pins extend to engage the Side members, as shown in Fig. 3.

In the moulding strips 21 I provide short ratchet plates 21a with which the pins 33 co-act to hold the sash 17 in a slightly tipped or swung inward position.

Secured to the bottoni of each sash are plates 34 (see Fig. 12) each of which carries a laterally projecting tongue extension 35. Each tongue extension is elliptical in cross section with its major axis arranged vertically, and the extreme end of said tongue is bevelled off as at 35u. The tongue 35 of each plate normally extends into a recess 36 in an associated block 37 (see Fig. 11) located in each of the frame grooves 24-25, there being a pair of such blocks for each' sash 16 and 17. In the case of the pair of blocks associated with the top sash, they are arranged, one within each channel 26. The recess 36 in each block opens through one edge thereof and includes a bevelled end wall or surface 38 which co-acts with the bevelled end 35 of the tongue 35, as will later appear. In each block is provided a vertically disposed opening 3i) to receive the knotted end of a sash cord 40, the cords passing over the usual pulleys 41 in the top ends of the side frame members, to bc secured to the associated window weights i the usual manner. (See Fig. 4.)

Then the sash is in its normally upright closed position the major axis of each tongue 235 extends vertically in the associated recess :E6 so that the blocks are free to slide in the frame grooves with the sash (see Figs. 7 and. 9) when the lower sash is swung inwardly about said tongue as pivots, the engagement of the tongues in said recesses will not only force said blocks against the parting strips 23 but will, on account of the coacting bevelled surfaces 35 and 38 force said blocks laterally outwardso that they will frictionally engage with the adjacent Y parts of the frame and lock said sash against vertical movement after it has been swung inwardly. In the case of the blocks associated with the top sash 16, said blocks are moved to engage parts of the channel strips 26 in a like manner. Thus no matter in what vertical position either sash may be in, when it is swung inwardly it is automatically locked against further vertical sliding movement in the frame in either direction.

In addition to the automatic locking means just described, I may also employ in conncctiontwith the lower sash 17, another locking means which is brought into operation when said bottom sash is in its substantially lowest position in the frame. Such means is as follows: To the side members of the frame, just inward of the moulding, strips 21 and near the sill 20, I secure plates 42 each of which includes a lateral hook extension 43. Fixed to the inner face of the sash members 17 b near the bottom, are plates 44, each of which includes an inwardly projeeting bottom hoolr- 45 and an inwardly projecting top lug 46. When it is desired toswmg the bottom sash inwardly beyond that position in which it can be locked by the pins 33 and toothed plates 21, said pins are first withdrawn and the sash is then swung inwardly until the lugs 46 engage beneath the ends of the hooks 43 on the frame plates 42. When the ysash is in this position, as shown in Fig. 5, the enoutside thereof, it is pushed outwardly to 1 disengage the hooks 43 and lugs 46 and then raised a short distance, after which it is swung inwardly until the hooks 45 engage the ends of the hooks 43 and the lugs 46 engage the top of said hooks 43, as shown in Fig. 6. The sash is now locked in a position convenient for cleaning the outside of the same. To facilitate the inward and outward swinging movement of the bottom sash, I provide a handle 47 atv the top end thereof.

By reason of the engagement of the Hanges 27-28 of the channel strips 26, in the grooves 16n and 17a of the sash, said channel may shift laterally, in or out of its associated frame groove to accommodate itself to any contraction or expansion of the sash and thus a Weather tight connection is provided between the frame and sash at all times.

While, in describing my invention, I have referred to certain details of mechanical construction and arrangement of parts, I do not wish to be limited thereto except as may be pointed out in the appended claims.

I claim as my invention:

1. In combination with a Window frame and a sash which is capable of either a vertical sliding movement or an inward swinging movement about a horizontal axis with respect to said frame, means providing al, shdmg guldmg bearing for the sash m the frame, and coacting hook members on the sash and frame respectively adapted for engagement with each other when the Sash has been swung inwardly, to lock said sash against vertical movement with respect to the frame.

i2. lIn combination with a window frame and a sash which is capable of either a vertical sliding movement or an inward swinging movement with respect to said frame, means providing a sliding guiding bearing for the sash in the frame including a part pivoted to the sash and adapted for engagement with a fixed part of the frame, and coacting hook members on the sash and frame respectively adapted for engagement with each other when said sash has been swung inwardly, to limit the inward swing of said sash and also to lock said sash against vertical movement with respect to the frame.

3. In combination with a window frame and a sash which is capable of eitherv a vertical sliding. movement or an inward swinging movement with respect to said frame, means providing a sliding guiding bearing for the sash in the frame including a part pivoted to the sash and adapted for engagement with a fiiied part of the frame, and coacting hook members on the sash and frame respectively, adapted for engagement to lock the sash against vertical movement in the frame when said sash has been l swung inward into one position, and to lock the sash after it has been swung further inward into a second position, against both a vertical sliding movement in the frame and a further inward swinging movement.

4. In combination with a window frame having grooves in its side members, and a sash which is capable of either a vertical sliding movement or an inward swinging movement wit-h respect to said frame, a block in each frame groove, window cords fixed to the said blocks, and plates fixed to the sash, said plates and blocks having a tongue and recess connection, which in the inward swinging movement of the sash acts to force the blocks into frictional engagement with the walls of the associated groove to lock the sash against a vertical movement in the frame.

5. In colnbination with a window'frame having grooves in the side members, and a sash which is capable of either a vertical slidingA movement or an inward swinging movement with respectto said frame, a recessed block in each sash groove window cords connected to the said blocks, plates fixed to the sash, said plates having tongue extensions which project into the recesses of said blocks, said tongue extensions acting when the sash is swung inwardly, to shift the blocks in a direction at right angles to the4 sash cords, to frictionally engage the walls of the frame grooves and lock the sash against a vertical movement in the frame.

6. In a window construction, the combination of a Window cord block adapted for movement in a window frame groove, said block havin a recess therein, a tongue extension adapte to be carried by the sash,

vsaid tongue extension normally engaging in said recess, said extension ybeing of such shape that when the sash is swung inwardly into an open position the block is shifted into engagement with the window frame to lock the sash when open against vertical movement in the frame.

7. In combination with a window frame having side members provided with inner and outersash' grooves, top and bottom window sash, slidable in said grooves and each having a groove in the outer surface of its side members, channel strips each having a flange which enters 4into a respective groove in the outer surface of the side members of both window sash.

In testimony .that I claim the foregoing as my invention, I aix my signature this 29th day of April, A. D. 1922.

JOSEPH SYLVAN.
