FRAME lAND SASHI CONSTRUCTION'.

andi; Sash Constructions, of which the following is a specification, reference being had thereiny to the accompanying drawings.

,This invention relates to a frame and sash construction for. windows, transoms, ventilators and compositel or folding windows,

either of the outward or inward opening type, the construction being associated, when necessary, with weather bars, condensatlon gutters, and any architectural design of window construction which will afford maximum sight lines, either with single or double glazing. f

My invention aims to furnish .a window frame with outwardly opening sashes that may be easily and quickly adjusted and safely supported forA a desired degree of ventilation, the sashes being disposed so as to be adjusted at any desired angle relative to the frame, it being possible to reverse a sash so as to provide a maximum frame opening for ventilation in a desired direction and to be easily cleaned from inside.

My invention further aims to furnish the sashes of a window with novel meeting rails or members which' will insure a positive connection between the sashes when closed, and at the same time permit of an angular adjustment of either sash. The sashes furthermore include novel means for holding the meeting rails in adjusted positions relative to the casing frame so that when the sashes are braced in their angular positions there is no danger of accidental displacement.

My invention is further characterized by j a frame having a transverse hinge member slidable therein and to which a sash is hinged 0r otherwise connected, said hinge member having its ends held so that it may be safely adjusted without any danger of sash displacement.

My invention further aims to provide a windowconstruction 'wherein the parts are made with a view of reducing the cost of Specification of Letters Patent. Patented J une 21, 1921. Application led August 1, 1919. Serial No. 314,606.

manufacture and at the same time retain those features by which durability and ease of assembling are secured. With such ends 1n v1ew my invention resides in the novel construction to be hereinafter considered and then claimed. 1

Reference will now be had to tlie drawin s, whereinigure'l is a front elevation of a portion of a window frame and sashes in accordance with my invention, showing the outer side of the frame; j

Fig. 2 is a vertical sectional view of a portion of the same showing a sashrin an adjusted position in full lines and otherpositions indicated by dash lines;

Fig. 3 is an enlarged horizontal sectional view taken on the line III--III of Fig. 2, an

Fig. 4 is an enlarged cross sectional view of the meetin the line IV-IV of Fig. 1.

In the drawings, the reference numeral 1 denotes a channel window frame made of solid steel with the top, bottom and side members thereof channel shaped in cross section so as to provide an inner leg 2 and an outer leg or facing 3, which is of greater depth than the innerv leg 2 so as to aflord a seat 4:. As brought out in Fig. 3, the inner leg 2 has a beveled outer face 5, and the outer leg 3, adjacent the seat 4, has inner beveled face 6, the faces 5 and 6, particularly at the sides of the frame, affording a wedging or seating action of the sash relative to the frame.

One or more sashes may be associated with the frame depending on the nature of the window and considering superposed sashes, both of which may be opened outwardly, each sash comprising a hinged rail 7 side rails 8 and a bottom rail 9. Since the sashes are superposed, the hinge rail 7 of the lower sash serves as a meeting rail in conjunction with the bottom rail 9 of the upper sash, as brought out in Fig. 4. The rails of each sash coperate in supporting suitable glazing, generally designated 10, and the side and bottom rails have a cross sectional shape which will provide inner le s 11 and outer legs 12, said legs having beve ed faces 13 and inner sides thereof. This 14 respectivel adapted vto confront and sesit on the beyveled faces 5 and 6 of the -

frame legs

2 and 3 respectively;

When the sashes are closed the legs will coperate with the channel lframes in forming inclosed spaces 15 about the top and bottom of the sashes and it is in the side spaces 15 that provision is made for supportinghthe sashes. f

The inge rails 7 of the sashes are. substantially the same cross sectional shape as the side and bottom rails, but are reversed, as is apparent in Fi 4, so that the long le of said hinge rai s will be at the outer si es of the sashes, and the short legs at the rmits of the long and short legs of the hlnge rails meeting the short and long legs of an ad]o1n1ng rail, for instance, the hinge rail 7 of the lower sash meets the bottom rail 9 of the up er sash and the hinge rail of the upper sas meets the top ofthe frame 1.' vSince the relation of these meeting parts are identical as well as other partsy of the superposed sashes, I deem it only necessary from now on to consider the construction of one of said sashes and the adjustment thereof. l.

Taln'ng as an instance, the hinged rail 7 of the lower sash, said rail has hinge members 16 fastened thereto by screws or other means, designated 17 and these hinge mem# bers are connected to a transverse hinge.

member 18 having angular ends 18 that extend downwardly into the side spaces 15 at the upper end of the lower sash. The

, hinge

members

16 and 18 have the usual barrels'connected by pivot pins, and the angular ends of said'hinge member 18 have a sliding contact in the channels of the sides of the frame 1.

Suitably connected to the inner walls of the side channels of the frame 1 are channel shaped wear members 19 and it is in these members that the angular ends 18n of the hinge member 18 slide and are frictionally held by flat compression springs 20 connected to the angular ends of the hinge member b screws 21. Additional screws 22 are emp oyed forincreasing the tension of the compression springs 20 and after the tension of said springs-has been regulated, then the.

screws 21 may be tightened to hold said spring. It 1s now apparent that the lower end of the sash may be swung outwardly and the upper hinged end thereof lowered in the frame 1. The vsash may be placed at an acute anglerelative to the frame as shown by full lines in 1+`ig.`2; swung to an angle of ninety degrees, as shown by dash lines in the same figure, or the sash reversed so that the outer side Vof the sash will be disposed -at an acute angle relative to lsaid frame and be easily and safely cleaned from inside.

g To hold .the lower sash in an adjusted position pivoted braces or arms 23 are eind 1, at the lower end thereof, said spacer blocksbeing held by screws-26 or other fastening means. The outer ends of the braces or arms 23 are pivotally connected, as at 27 to spacerblocks 28 fixed on the side rails 8 of the lower sash adjacent the upper, end thereof, so that said braces or arms will represent the hypotenuse of a right angle triangle at each side of the sash when sald sash is in a horizontal position such as indicated in Fig. 2. It is then possible for the braces or arms to support the sash in adjusted positions at any angle relative to the frame.

' When the llower 'sash is reversed or the hinge member thereof carried to an extremely low position in the frame 1, the' spacer blocks 25 'serve as end abutments to limit the lowering movement'of the hinged l edge of the sash, and when the sash isclosed the pvoted braces or arms 23 are concealed: within the side spaces 15, as brought out in Fig. 3, consequently the complete window vhas anormal visual appearance as though 'lower sash and the bottom rail 9 of the upper sash, and that the upper sash is held in a closed position by the .lower sash.` This obviates the necessity of using a sash lock at themeeting rails of the sashes since the hinge rail 7 ofthe lower sash provides an abutment for the inner leg .of the bottom rail of the upper sash. It is therefore necessary to open the lower sash and lower the meeting rail thereof before theupper sash can be swung to an open position.

Since the upper and lower sashes. are adapted to swing outwardly, it is necessary that the legs 11 be cut away, as at 30, so that the side rails of the sashes will provide clearance for the angular ends of the hinge members. The cut away portions of the leg 11 may be closed by extensions of vthe leg 2, which` have not been shown, so that the cut away portions 30 may beclearly shown.

v It is obvious thatsince the sashes ma be swung outwardly that any curtain, sha e or the like, carried thereby, will be protected and function as an aw While in the drawings there is illustrated a window construction as now in use, itis to be understood that the structural elements entering into the invention are susceptible to such variations and modifications as fall within the scope of the appended claims.

What I claim is l. In a window construction, a channel frame having inner and outer legs provided with beveled faces, outwardly opening sashes in said frame, means transversely of said frame hingedly supporting said sashes at points removed from the sides of said frame, each sash having channel rails with inner and outer legs providing beveled faces adapted to engage the beveled faces of said frame, the legs of said frame and sashes cooperating in providing spaces in said frame, and means in the spaces of said frame cooperating with the rst mentioned means for supporting said sashes for adjustment relative to said frame.

2. In a window constructiom a channel frame having inner and outer legs provided with beveled faces, outwardly openingsashes in said-frame, each sash having channel rails with inner and outer legs providing beveled faces adapted to engage the beveled faces of said frame, the legs of said frame and sashes cooperating in providing spaces in said frame, angular hinge members slidable in the spaces of said frame and supporting said sashes for adjustment relative toi sald frame, and means bracing sald sashes when open, said means bein otherwise concealed by said frame and sas es.

3. A window comprising a frame, outwardly opening upper and lower sashes in said frame, and hinge members carried b the top rails of said sashes and having en s thereof slidable in said frame, the hinge member of the lower sash forming an abutment for the lower rail of the upper sash to 5. A window construction as characterized in claim 4, wherein said frame has wear members set therein for the ends of said transverse member.

6. A window construction as characterized in claim 4, wherein the transverse member has depending ends preventing. a turning movement of said transverse member in saidV frame,

7. In a window construction, a frame, superposed sashes in said frame and having meeting rails, and a transverse member hingedly attached to one of said sashes and movable in saidframe said transverse member being inclosed by the meeting rails of said sashes when said sashes are closed.

8. In a window construction as characterized in claim 7, the said transverse member having depending ends in said frame and the sash hingesset in from the ends of said transverse member.

9. A window construction as characterized in claim 7 and wherein additional means carried by the depending ends of said transverse member produces a frictional contact for the ends of said transverse member.
