METALLIC FRAME.

, frames for metallic doors.

The invention is of particular utility in a metallic window-sash for a building or a railway-car, and I will describe an embodiment. of my invention in this form, but. I Wish it. understood that certain of the fea tures of my invention are equally applicable to metallic Window-frames and frames for metallic doors.

The object of the invent-ion is to provide a metallic frame for the uses above mentioned, which possesses great strength and is of light weight, which may be manufactured at low cost and which is of attractive appearance.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, in-which- Figure 1" is'a' front View of a Window; Figs. 2, 3 and 4- are sectional views on lines 22, 3-3 and 4-4:, respectively, of Fig. 1; Fig. 5 is a sectional detail view on line 5-5 of Fig. 1; and Fig. 6 is a front view of a modified form of window.

Referring to these drawings, the frame consists of frame-members secured together at their ends forming, in the preferred embodiment ofthe invention, ,a rectangular' frame consisting of side-members land 2. a. bottom member 3, and a top member l.

The side-members 1 and 2'are preferably constructed as shown in Fig. 3, from which it will be seen that the frame-member consists of a single strip of sheet-metal 5 bent on lines extending lengthwise thereof to a rectangular cross-section and to provide a fold 6 at one edged the strip inclosing a flange 7 at the other edge thereof. By this construction, a metallic frame is obtained which possesses great strength, which may be manufactured at very low cost, and which is provided with a flange extendin inwardly of the frame-member and adapted Specification of Letters Patent.

to position a panel lying Within the frame, as, for instance, a pane of glass 8.

The bottom member 3 of the frame may be constructed in a manner similar to that above described, but it is preferably of somewhat greater width and its lower edge is inclined somewhat, as illustrated in Fig. 4. The ends of the bottom member 3 are se cured to the lower ends of the side- members 1 and 2 by welding these ends together, as. in this vay a unitary structure is produced 65 possessing great strength and a smooth surfare is presented at the joint that the line of the joint does not show when the frame is completes lreparatorv to making the Weld. the inimrdly extol. 2. l .i' es on'the 7e frame-members formed hinges 7 are mitered as shots .i .n e

l the lines 9 of l. 'lhe eii ids and bottom members which-are to joined may he miter-ed enti ely the members if desired, but the con tion which 1 prefer to employ is that llli" trated in Fig.1 and shove descrih i a the lines of Welding extend in the of the length of the side-mem er this construction is employed, means for closing the lower ends oi ti members 1 and 2. For this purpose. of sheet-metal 10- of channel-section 1.. be inserted within the end of each of the members, so that the lower face of this once lies in the plane of the" go of the bottom member 3 and the flanges at the sides of this lower face are secured to the of the I side-members l and 2 hold the piece in position.

The top member of the frame may he Slil'l'l: lar to the side -members construction nit may he secured at its en the upper e. s of the side members int s manner shove de' scribed in connection Jith the bottom memher 3. However, I prcfer'to t. we the top member of the rounded co as at the Thus in l, l have sh" 11 and 12, which are we to the upper ends of the side-members l 1 1d. 2 along the reg lines 9, and a top member 4.- similar to the side-memhers in construction and having its ends welded to the adjacent ends of the corne pieces corner-pieces l1 and 12 along the lines 9. lo the construction of the corner- pieces 11 and 12, I employ two sheet-metal pieces, each constituting one face of the corner piece and a portion of each 01' the edges thereof, this construction being illustrated in Fig.2. The two sheet-inetal pieces are shown zit l3 and 14, and'each is provided with a flange extending around the edges of the piece. The shape of these pieces and of the flanges 15 at the inner edges thereof is such as to provide the rounded corner shown in Fig. 1. One ofthe flanges lfris provided with. a fold 6' and the other with a flange 7 hold the two pieces 13 and :14 together along this edge of the corner-pieee. At the other edges. the flanges on the pieces 13 and 14 overlap as shown in Fig.2 and are secured together in any suitable manner, as by means of rivets 16.

If desired, I may modify the construction n a sash made of steel and adapted to 1 up and down in a frame, the rubbing otthe edges of the sash on the frame sometimes wears off theenamel coating of the frame andrusting takes place quite rapidly. especially on the outer side of the sasln abutting the corresponding end edges of said which is more exposed. To guard against this, I pi ovide the opposite edges ot the sash with strips of metal which will not rust. 'lhusin Figs. 1 and 3, I have shown U- shaped strips 24'inclosing the outer edges of the side-members 1 and and see: ed theret h in any suitable manner, those ps being'n'iadc ot brass. It desired, a similar strip (Fig. 1) may be secured to the lower edge of the bottom member 3.

venience of having the sash stick in its frame by reason oi the rust is avoided.

Having described my invention, what. I claim as new therein and desire to secure by Letters Patent of the United States is:

1. A frame consisting oi shcet'metal frame-niembers and corner-pieces secured together, each of said cornoupieces consist ion of two sheet-metal plates flanged at their edges and having said Flanges secured. tog ther. said plates being so shaped as to inclosed by this fold, so as to \Yith a. sash provided with such bras rol'ihing strips; rusting Will not take pla and the inconform rounded corners at the inner edges thercot', substantially as set forth.

11A frame con.

mg of sheet-metal frame-members and corneupieccs secured together, 81011 of said gnrncnpieces cons-isting of two sheet-metal plates flanged at their outer edges and having said flanges secured together one of said plates being provided with a flange at its inner edge and the other a fold inclosing said flange and said plates being shaped to provide rounded corners at the inner edges thereof, substantially as set forth.

3. A. frame consisting of frame-members and corner-pieces secured together each of said frame-members being formed of a single strip of sheet-metal pressed to a rectangular cross-section and hav ng the lateral edges thereof secured together by means of a flange at one edge and a fold at the other inclosing said flange, and said corner-pieces each consisting of two sheet-metal plates flanged at their outer edges and having said edges secured together, one of said plates being provided with a flange at its inner edge and the other a fold inclosing said flange and said plates being shaped to rovidc rounded corners at the inner e ges thereof, substantially as set forth.

4. A frame consisting of frameauemoers each formed of a single 'strip of shcetsmetal bent to a rectangular cross-section and having the lateral edges thereof secured together; and sheetanetal corner-pieces of rectangular cross-section and of the same thickness as said members, each of said members and pieces having an inwardly extending flange thereon. and the edges of the sheetmetal of said members at the ends thereof pieces and being welded directly thereto, substantially as set forth.

5. A window sash comprising end and side rails of tubing, and tubular sheet metal corner pieces formed without transverse o1 miter joints, the ends of said corner pieces abutting the adjacent ends of said end and side rails and united thereto to form contiuuations thereof.

(3. A window sash comprising end and side rails of tubin and tubular metal corner pieces former without transverse or miter joints and having their ends welded to the adjacent; ends ofthe end and side rails to form continuations thereof.
