T o all lwhom it may concern:

19 which extends upwardly on the inside of Be it known that I, NInLs PoULsoN, of 1,. the sash when the latter is in ils lowest po- Brooklyn, in the county of Kings and in th(` State of New York, have invented certain new and useful Improvements in Reversible lindowsg and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the acci'nnpanying drawings, in which- .liignre l is a front elevation of a window construction embodying my invention, the window being closed; Fig. 2 is ar similar view, the window being open; Fig. 3 is a vertical longitudinal section through the center of Fig. l showing the sashes in proper position preparatory to swinging; Fig. a is a. vertical longitudinal section similar to Fig. 2, but on an enlarged scale, portions being broken away to shorten the view; Fig. .5 is a horizontal sectional view taken on the line 5---5 of Fig. 2, the section being on an enlarged scale and shortened by breaking away the middle portions; Itig. (l is an enlarged sectional view similar to Fig. 3, showing the sash partly turned upon their pivots; Fig. T an enlarged front` elevation of the central portion ot' Fig. i), the upper and lower parts of the frame heilig omitted; Fig. S is an enlarged detail view showing the construction ol the parts about the pivots; and Fig. El is an enlarged detail view of a portion of the window frame and pivoted sash traine.

The object. ot' my invention has been to provide a metal window construction having the advantages hereinafter epecilied; and to such ends my invention consists in the window construction hereinafter specitied.

In carrying my invention into practice, I provide a window frame, preferably cousisting of sheet metal lilled with cement. `Such frame preferably has its lintel and jan'lbs of the ,saine construction. The lintel has a sheet metal 'facing 11 which has tiange 1Q that` is seated in a groove in the cement of the jamb. There is au outer facing 13 having a` similar flange 14, and also having a shoulder l5 to bear against the side ot' the window opening, the shoulder l5 preferably having a beveled face so as to eli'ectively retain a rubber or other packing 16 to make a tight joint. The windowsill 17 is preferably a cast shell lilled with cement t8, the casting having a beveled upper face or water table, and having a ledge sition.

I provide an upper sash Q0 and a lower sash 21 which are capable of the usual vertical movements, and can also be swung about a horizontal pivot, as will be described in detail. The pivot construction is as follows: There is a block Q2 which is removably secured in a. socket Jformed in the sheet metal facing Q3 of each amb, the block heilig secured in place by screws B4- A screw 25 passes through the block and is threaded into a T-bar Q6. The T-bar is fastened to a channel having a central rectangular raised portion 2T and two outer rectangular raised portions 2S. A cross bar 29 connects the T-bars on opposite sides of the window, the cross bar having plates 30 at each end which are secured by screws 31 Fig. S to the T-bar. Each ot the rectangular portions 2S of the channel has within it a packing 3Q, preferably in the form ot' a rubber tube, to make a tight joint between the channel and the facing The groove between the outer raised portion Q8 ol the channel and the central raised portion 2(3 thereof is occupied by an L-shaped tiange 33 formed on the plate 3ft, which latter is the main portion of the upper window sash 2t). Similarly the lower window sash has an L- shaped flange 35 occupying the corresponding seats between the inner raised portion 2S and the central one 2G. The L-shaped flange of the sash interlocks with the Hange of the T-bar in such a way that while freedom of movement may be permitted, a wind and rain tight joint is formed. The glass S6 is held against the plate 34 by Z-shaped bars 37 secured around the opening. The upper bar is preferably removably attached, as by screws, for the purpose of removing and replacing the glass.

In order that the sashes may always be symmetrically disposed with reference to the pivots so that their weight shall be balanced about the pivots, the central bar 2t), extending from pivot to pivot, has a central pivot 3S ot a lazy tongs fastened thereto, each end of the lazy tongs being pivoted to a T-bar 39, which is fastened to the horizontal portion -10 of an L-shaped bar, whose4 vertical portion eil is secured to the main plate of the corresponding window sash. The channel bars and the T-bars QG have their upper and lower edges formed on the arcs of a circle l2 IUD so that they and the sash can be rotated about the pivots when the sash are wholly within the said circle. Channels 43 and T-hars Ll-l llig. l are secured to the faces of the jatnbs above and below the pivoted channels and T-hars. but in alinement therewith, to guide and hold the sash when they are moved up and down away trom the central bar. Sheet nietal heads `l5 and 4G are secured to thc iniderl'ace ot the lin tcl to receive thc upper edge of the upper sash,

I n order to lock the sash in their extended positions some t'orm ot catch is provided to secure the lower edge oil' the lower sash to the sill. That torxn ot catch which I prefer consists ot a plate at? pivoted upon a screw lo that is secured in the sill, the plate preterahly having a handle 4D at each end. The said plate carries a hook which can he swung over a lug 5l formed on or secured to the lower rail ot' the lower sash.

In order to lock the pivoted channels from rotation and to assist in making a wind tight joint, plates 52 Fig. Q are fastened by screws to the fat-ing Il, the said plates having inclined slots in which the grooves are received, so that when the plates are raised the inclination ol the slots causes them to be retracted from the window opening, and when they are lowered to be forced into the window opening.

In the operation ot my window, assuming the window to be in the closed position in which thc sash are at their extreme upper and lower limits, the plate 4t7 Fig. 2, is tilted to the right so that the hook 50 is swung from over the lug 51. The lower sash is then raised and the lazy tongs causes the upper sash to simultaneously move downward and keeps the two sash symmetrically placed with reference to the axis through the pivots so that the weight of one sash always balances that of the other about the pivots. As the movements of the sashes are always in opposite directions they balance each others weight so that no window weights are required. When the sashes are wholly contained within the guides of thc pivoted channel and T-bar, and the plates are retracted from the window opening. the said pivoted channels and T-bars, together with the sashes, can be swung on the pivots to a horizontal position. thus leaving the window opening practically unobstructed; or the sash can be reversed so that the outer side of the upper sash becomes the inner side of the lower sash, and can thus be cleaned from the inside ot the room. It is thus easy to clean both sides of both sashcs without reaching out of the window, a very important consideration. lhen it is desired to close the window opening, the pivotetl channels and the sashes are swung to a vertical position, the plates 52 are moved downward and inward, thus projecting over the pivoted channels and holding the sash in line with the upper and lower stationary channels. Upon pulling down the lower sash it readily enters the guides in the lower stationary channels, and at the same time the upper sash passes into the guides of the upper stationary channel. lVhcn the sashes are in thci r upper and lower positions, the lazy tongs and central bar are entirely concealed within thc L-shapcd meeting rails of the sashes.

It will be observed that my window construction has the following advantages: It requires no window weights, and therefore the construction ot the window traine is exceedingly simple. lt is entirely made ot metal, and yet is so constructed that all of the metal used except the sill is rolled metal, and is therefore cheap and durable. It can be opened so that practically the entire window opening is unobstructed. Because the sashes can he reversed, both sides of both glasses can be cleaned from within the room. The glass can be readily replaced when broken.

While I have illustrated that embodiment of my invention which I prefer, it will be understood that there are many changes which could be made in the illustrated construction which would he within the scope of my invention, and I desire not to be limited beyond the necessary intcndment of my claims and the requirements of the prior art.

I claim:
