METALLIC WINDOW FRAM' E AND SASH.

SPECIFICATION forming part of Letters Patent No. 714,254, dated November 1902. Application filed May 19, 1902. Serial No. 107,939. (No model.)

Be itknown that I, HERBERT A. STREETER, a citizen of the United States, residing in Ohicagopin the county of Cook and State of Illinois, have invented a new and useful Improvement in Metallic Window Frames and on1ine77of Fig. 6.

Sash, of which the following is a specification.

My invention relates to improvements in metallic windows, and more particularly to the construction of the window frame and sash.

The object of my invention is to provide a. fireproof window frame and sash of a simple, efficient, strong, durable, and economical construction.

My invention consists in the novel construction of parts and devices and the novel combination of parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of a window embodying my invention. Fig. 2 is a horizontal cross-section on line 2 2 of Fig. 1. Fig. 3 is a vertical section on line 33 of Fig. 1. Fig. 4 is an enlarged section similar toFig. 3, but showing the window open, the lower sash being raised and the upper one lowered. Fig. 5 is a detail vertical section on line 5 5 of Fig.3. Fig. 6 is a detail vertical section through one of the sash on line 6 6 of Fig. 1. Fig. 7 is a detail section Fig. 8 is a detail top view showing one corner of one of the sash. Fig. 9 is a section on line 9 9 of Fig. 8. Fig. 10 is a sectional view showing a modified construction of the window-frame.

In the drawings like letters of reference indicate like parts in all the figures.

In said drawings, A represents the wall of the building.

B B are upright steelchannel-bars forming the sides of the metallic window-frame, and.

B" B are upper and lower channel-bars forming the top and bottom of the window-frame and against which the ends of the side framebars B B abut and to which the same are firmly secured by angle-plates B fitting in 1 the angles formed by theprojecting ends Bi of the horizontal frame-bars B B Rivets b areinserted through the angle-plates and theframe-bars, as will be readily understood from Fig. 5. The projecting ends B also groove or channel I) of the channel-bars also affords anchorage between the window-frame and the wall of the building, and being filled in with mortar forms a perfectly tight joint between the window-frame and the wall of the building, free from cracks and crevices, as the metallic window-frame will not shrink or warp.

The side frame-bars B B are furnished on their inner faces with guide rails or ribs Z1 the same being removably secured to the frame-bars by screws b although one of the marginal guide-rails b may, if desired, be formed integral with the side bars, as the sash-frames can be inserted if only two of the guide-rails are removable. The upper horizontal frame-bar B is also furnished on its inner face with similar or corresponding guide-rails 11 all of which may, if desired, be formed integral with the upper channelbar 13. The lower horizontal window-frame bar 13 is furnished with a single guide rib or rail (9 on its inner edge, as the other guiderails are not required on this lower framebar B and their presence would form channels in the upper surface of the lower bar for collection of water and dust.

The upper and lower window-sash D D have each vertical rolled-steel side bars cl d and horizontal bars cl d, the side and horizontal bars being each furnished with integral flanges d on their inner faces for the panes of glass 0 to fit against. The side and horizontal barsd cl are firmly and rigidly secured together at the corners thereof by projecting tongues d on the ends of the side bars which extend through suitable openings 01 in the horizontal bar 01 and which are upset or riveted, as will be readily understood from Figs. 8 and 9. Each of the sash D D is also furnished with one or more divisionrails d having flanges d d to receive and i supportthe glass and provided with tongues d? at their ends which project through suitableopenings d in the sash-frame bars d and which are upset or riveted to secure the division-rails in place.

E represents the putty for securing the glass panes C in place on the sash-frames. The upperframe-bar cl of the lower sash D is furnished with a stop-plate F on its upper face the outer edge of which overlaps the projecting web d of the lower bar d of the upper sash D when the windows are closed, as illustrated in Fig. 3, thus preventing any crevice or opening between the horizontal frame-bars of the two sash when the window is closed. This stop-plate F also underlaps and engages the corresponding projecting web d of the upper horizontal bar d of the upper sash when the Windows are open, as illustrated in Fig. 4, and thus preventing the sash from passing each other.

G G are sash-pulleys inclosed in suitable metallic boxes or cases G, resting upon the upper window-frame bar B and in or upon which the shaft g of the pulley is journaled. H is a sash-line, preferably a cord or chain, passing over the sash-pulley and having its ends secured to the sash D D through the connecting eyes h, which are attached to the upright bars (1 of the sash-frame by screws h. The pulley G is mounted centrally above the sash and equals in diameter the distance between the points of connection of the two ends of the sash-line with the sash D D. The sashline H extends through suitable holes oropenings d d in the upper horizontal frame pieces of the sash, these openings or points of connectionsof the sash-line with the sash being each located in the vertical plane of the center of gravity of each sash, so that the sash may slide freely up and down in the sashguideways 17 formed on the sash by the guide rails or ribs 12 Each of the sash-pulleys G is located directly above the upper ends of the side bars B B of the window-frame, so that the sashlines H H fit centrally in the sashways 12 formed by the guide rails or ribs b 19 The sash-pulleys are mounted transversely of the plane of the sashthat is to say, their axes or shafts extend parallel to the planes of the sash. In this way one sash balances the other, and sash-weights as well as boxes or ways for the sash-weights are dispensed with, and the necessity for duplicating the sash-pulleys is also avoided.

In the modification illustrated in Fig. 10 the sash-frame instead of being composed of channel-bars is made of a pair of angle-bars P P, riveted to a connecting flat bar P, which together form, in effect, a channel-bar.

I claim- 1. The combination in a window of a pair of upright window-frame channel-bars B B, horizontal window-frame channel-bars B B having ends B projecting beyond said up right bars and secured thereto by angle-plates B said upright channel-bars being furnished on their inner faces with guide ribs or rails b forming ways b for the sash, a pair of metal sash D D each having upright metal side bars d d and horizontal bars d d furnished on their inner faces with integral flanges (Z for the panes of glass to fit against and secured together at their corners by interfitting tongues d and openings 61 the lower sash beingprovided with a stop-plate F on its upper horizontal frame-bar d, sash-pulleys G G mounted transversely and centrally on the upper horizontal Window-frame channel-bar B and sash-lines H passing over said pulleys and having their ends secured to the sash D D, each strand of the sash-lines fitting centrally in the sashways formed by the guide ribs or rails on the upright window-frame channel-bars B B, substantially as specified.

2. In a metal window, the combination with upright window-frame channel-bars B B provided with guide rails or ribs 12 forming ways I) for the sash, and horizontal window-frame channel-bars B B of a pair of metal sash D D, a pair of pulleys G G mounted transversely on the upper frame-bar B and centrally over said ways 19 and lines H passing over said pulleys and having each one end attached to each sash, substantially as specified.
