SWINGTNGWVINDOW STRUCTURE.

Application fil ed April. 23, 1925. Serial No. 25,254.

Structure, of which the following is a speci fication.

In general my invention relates to that type of window in which the sash both slides vertically and swings on a horizontal axis relative to the window frame.

In this character of window the sash is pivoted on a horizontal axis between a pair of vertically disposed sash-bars which are p in turn slidably mounted in the window frame and which are usually provided with the conventional cords and weights; and my invention particularly relates to the mounting of the sash on the sash-bars and the packing between thesame which, without interfering with the pivotal movement of the window, provides an air-tight joint when the sash is vertical and also prevents rattling.

In the accompanying drawings wherein I lllustrate the application of my invention,

Fig. 1 is an inside elevation of:a window.

frame provided with an upper and lower sash, the upper sash being shown in its closed or vertical position while the lower sash is swung on a horizontal ariis into a tilted position; Fig. 2 is an enlarged broken vertical section of a sash taken along the line II- H in Fig. 3; Fig. 3 is a=broken horizontal section on enlarged scale and taken along the line IIIIII in Fig. 2, and Fig. 1 is' a broken section on the line IV-IV in Fig. 3.

The following is a detailed description of the drawings. 1

A 's the window frame which isshown of the conventional type provided at its vertical sides with grooves to receive the edges of the upper and lower sash. The upper sash is indicated at Band the lower sash at B Preferably both the upper and lower sash are constructed in accordance with my invention, but if desired one of them may be of the ordinary vertical sliding type. The sash are each mounted on a horizontal axis between pairs of sash-bars C which are mounted to slide in the usual sash-grooves in the window frame A. The bars C are n'eferably provided with the usual cords and weights.

The edges of the sash and the sash-bar are in flat surface contact when the sash is vertical as shown in Fig. At their centers the sash-bars G are pierced by horizontal circular holes whose outer portions are of greater diameter, thus providing an intermediate shoulder 1. The inner and smaller diameter of the hole is provided with a bushing 2 whose outer end has a foot flange 3 which is countersunk into the outer surface of the sash bar and attached in place by screws 4. 5 is a hollow. stud of proper which is countersunk in the edge of the sash and secured by screws 7 to said sash. The bore of the stud 5 is threaded to receive a screw 8 which extends through a washer 9 bearing against the end of the outer bushing 2. Thus the sash is pivoted on a horizontal axis between and to the bars C, the two flanges 3 and 6 forming a metallic hearing which assumes thewear from the wooden elements.

Each vertical edge of the sash is provided with a vertical slot 10 in which is mounted the metal channel member 11, the same being held in place by its rearwardly extending horizontal tongues 12 seated in recesses 13 in the upper and lower ends of the sash and held in place by screws 14.

15 is a metal packing bar having its front edge rounded and which is of proper widtl'i to fit in the channel 11. 16 represents screw bolts extending loosely through holes in the rear wall of the channel member 11 and having their front ends screwed into threaded holes in the bar 15. Helical springsl? are coiled about said bolts between the rear wall of the channel and the bar, thus resiliently forcing the bar outwardly. The heads of the screw-bolts prevent the dislodgment of the bar from the channel when the sash is swungfrom the vertical. The sash is provided with sockets 18 in the rear of the channel member to provide clearance for the inner ends and heads of the screw-bolts. Said bolts and springs are provided at proper intervals to properly support the packing bar in position.

Each of the sash-bars is provided with a trough shaped slot 19 which registers with the slot in the sash when the latter is vertical. The slot 19 is provided with a metal trough member 20'which is held in place on the bar by its end tongues 21 seated in recesses in the ends of the bar and attached by screws 22. The trough members 20 are of a flattened are cross-sectional shape with which the rounded edges of the bars 15 mate and into and out of engagement with which said bars may readily move as the window is swung on its axis.

It is evident that when the sash is in its vertical position the packing bars are forced in a resilient mating with the troughs and that an air-tight and rattle-proof joint is effected. It is further evident that when the window is swung out of the vertical the bars being spring mounted are readily disenaged from the troughs by the applicatlon of a slight force. It is also evident that when the window is swung back intothe ver-' tical thepacking bars will snap into mating engagement with the troughs.

hat I desire to claim is:-

1. In a sliding and swinging window structure the combination with a window frame, of a pair of sash-bars mounted to slide vertically in said frame and a window sash interposed between said bars, of a horizontally disposed journal member sunk into each of said sash-bars, a horizontally disposed stud extending from each vertical edge of said sash and journaled in the corresponding journal member, said studs havingthreaded bores, washers bearing against theends of said journal members and studs, and screws extending through said washers V and screwed into the threaded bores of said studs. v I

2. In a sliding and swinging window structure, the combination with a window frame,zof a pair of sash-bars mounted to slide vertically in said frame and a window sash interposed between said bars, of a horizontally disposed bushing sunk into each of said sash-bars, a horizontally disposed stud extending from each vertical edge of'said sash and journaled in the corresponding bushing, said studs having threaded bores, washers bearing againstthe ends of said bushings and studs, and screws extending through said washers and screwed into the threaded bores of said studs.

3. Inya sliding and swinging window structure, the combination with a window frame, of a pair of sash-bars mounted to slide vertically in said frame and a window sash interposed between said bars, of a h0rizontally disposed bushing sunk into each of said sash-bars and provided with a foot flange substantially flush with the surface of the bar, a horizontally disposed stud extending from each vertical edge of the sash and journaled in the corresponding bushing, said -stud having a foot flange in flat contact with the foot flange of the bushing, said studs being provided with threaded bores, washers bearing against the ends of said bushings and studs, and screws extending through said washers-and screwed into the threaded bores of said studs.

.4. In a sliding and swinging window structure, the combination with a window frame, of a pair of bars mounted to slide vertically therein and each having a vertical slot on its inner face, means whereby a sash is pivotally mounted between said bars'to swing'on ahorizontal axis, said sash interposed between said sash-bars and provided with vertical side grooves, a metal channel member mounted in each of said grooves, a packing-bar having'its outer end contoured to fit the slot on the sash-bar, members fixed to said packing-bar and extending throughthe rear wall of said metal channel, helical springs coiled about said members and tending to press said packing-bar outwardly, the inner ends of said members being provided with heads to prevent their disengagement from said channels.

5. In asliding and swinging window struc-- ture, the combination with a window frame, of a pair of bars mounted to slide vertically therein and each having a vertical slot won its inner face, means whereby a sash is pivotally mounted between said bars to swing on a horizontal axis, said sash interposed be tween said sash-bars and provided with ver- -tical side grooves, a metal channel member mounted in each of said grooves, a packing-bar having its outer end contoured to fit the slot on the sash-bar, bolts having their threadedends fixed to the packing-bar and extending rearwardly throughthe rear wall of the channel, and helical springs coiled about said bolts between the packing bar and the rear wall of the channel whereby said packing-bar is resiliently pressed outwardly, the heads of said bolts by engaging the rear of said channel preventing the dislodgment of the packing-bar from its channel.
