To all whom it. may concern:

Be it known that 1, JOSEPH LANG, a citizen of the Empire of Germany, residing at Mannheim, in the Empire of Germany, have invented a new and useful Window-Frame, of which the following is a speciiication.

My invention relates to window frames made from iron or steel sash-bars and rolled bars.

, l will now `roceed to describe my invention with re erence to the accoinpanying` drawings, in which- Figure 1 is an elevation of a finished iron or steel window frame, Fig. 1 is an end view of the saine, Fig. 2 is a perspective view of an interna-l l'rame piece cut away and slitted in the upper web and ready for bending, Fig. 3 is an elevation ot the saine after it has been bent, Fig. 4 is a similar elevation and a cross section through another internal frame piece which is straight and passes through the gap of the former, Figs. 3 and 4#l are similar to Figs. 3 and 4 and show modifications, Fig. 5 is an elevation ol' an end of an internal frame piece and a cross section through an external' trame piece, the former being cut out and. ready for the insertion in a hole ol the latter, Fig. 6 is a similar view alter the union of the two parts, Figs. 7, 9, 1t) and 11 are elevations of the four external frame pieces before their composition, Fig. 3 is an elevation ol' I i'our composed internal trame pieces, ot which the two long ones are cut out and bent in the manner shown at Fig. 3 and the two short pieces are straight and have been passed through the gaps oi the former, as is shown at Fig. 4, and the ends ol' all these pieces being eut out in the manner shown at Fig. 5, Fig. 12 is a side view of the ex terna/1 frame piece shown at Fig. 11, Figs. 13 to 16 illustrate the several steps in the procof welding the crossing points of two internal frame pieces.

Similar characters ol reference refer to similar parts throughout the several views.

For the manufacture of a rigid window trarne of iron or steel as shown at Figs. 1 and 1a four internal pieces 1, 1 and 2, 2 of sashiron or steel and four external pieces 3, 3 and 4, 4 of rolled iron or steel of the desired seetion are cut and the ends ol! the external pieces 3, 3 and 4, 4 are beveled oil', as is, shown at Figs. 7, 9, 1() and 11. The upper web of each internal piece 1 is on two places cut away so as to iorm two gaps a d e as Jis clearly shown at Fig. 2. The cutting ofl these gaps may be effected in any known manner, be it by means of a die and a stamp in a press or otherwise. Afterwards two slits b c and d f are made on both sides of each gap, the said slits being produced in any known manner, for example by means of a thin and 'tlat chisel, or a circular metal saw or a band metal saw or the like. The up er web of the internal piece 1 is thus divi ed from the lower triangular part by the two slits b c and d f. Thereupon the piece l is heated and so bent by pressing in any known manner as to form two gaps g shown in F ig. 3, through which the two pieces 2, 2 can pass, as is shown at Fig. 4. It depends upon the section ol the sash-bars what shape the gap g is to be given. A modification of the gap g is for example shown at Fig. 3a. It will be understood, that the length of the gap in the piece 1 before bending, in other words the distance between the two end faces a. b and e d in Fig. 2, requires to have such a size as to leave after bending a distance between them like the thickness of the upper web of the piece 2 (see Fig. 4) or nearly so. The ends of all the internal pieces 1, 1 and 2, 2 are then cut out to 'lit the cross section oi the external pieces 3, 3 and 4, 4 respectively as is clearly shown,

at Fig. 5, a projection 7L being left which is to pass through a rectangular hole i in the piece 3 or 4. The cutting of the ends of the pleces .1, l and 2, 2 may be eil'ected in any knowny manner, for example by means or a planing machine, the emery disk of a grinding Inachine, dies and stamps in a press or the like. The two holes i i in each external piece 3 or 4 may be cut in any known manner, for example by means o1 dies and stamps in a press.

The two internal pieces 2, 2 are passed through the gaps g of the two other internal pieces 1, 1 and the latter are adjusted on the former, so that the two short external pieces 4, 4 can be put over the projections h 7L oi the pieces 1, 1. The projections k L of the pieces 2, 2 are inserted in the holes i i of the two long external pieces 3, 3, so that the beveledolil ends oi' all the four external pieces 3, 4, 3, il touch each other' and the whole frame looks like Fig. 1. Thereupon the beveled-oill ends oi the external pieces 3,- 4, 3, 4 in Contact with each other are welded, preferably by means ol an oxyhydrogen-blowpipe. In this manner or in any other known and approved manner the four external pieces 3,3 and 4, 4 are turned into a rigid rectangular frame, in which the four internal pieces l, 1

ico

and 2 are we ded in their upper parts.

and 2, 2 are secured. The ends ZL ZL of these internal pieces, which project from the external pieces 3, 3 and 4, 4, are then riveted, as is shown in Fig. 6. VZhere so preferred, the rivetedgends Zt Zt may also be Welded on the external pieces by means of the oxyhydrogen-blowpipe .5 Without using the wire Fig. 1a shows the welded ends h ZL. The next step is to weld the crossing points of the internal pieces 1, 1 and 2, 2. According to my invention this welding is effected in the following manner: The oxyhydrogen blowpipe 5 is so applied as to direct the jet of oxyhydrogen to the point Where Vthe upper web of the piece 2 crosses that of the piece 1, see Fig. 13, so that the flame will melt the metal in the manner clearly shown at Fig. 14. Thereby a gap Z will be formed in the upper Webs of the crossing . pieces 1 and 2 and layers Zc Zc of molten metal of a varying shape Aand extension will be produced on the vertical sides of the upper webs as is illustrated in Fig. 14. Thereby one orboth joints between the up er Webs of the crossing pieces l For lling up the gap Z pieces of weldable metal (such as soft wrought-iron or the like) and of convenient shape are placed in the gap as is for example shown at Fig. 15, where the ieces are denoted by 7 and 8, 8. lThe oxy- Eydrogen-blow-pipe 5 is again a melting these pieces 7 and 8, 8 an ior welding them on the upper Webs of the crossing ieces 1 and 2 as is for example shown at Fig. 16. Thereby the upper parts of the end lfaces a Z) and e d of the upper web of the piece 1 (see Fig. 3) are rigidly connected with the upper web of the crossing piece 2, so that the so iinished window frame shown at Fig. 1 be ca able of withstanding forces to which it is su jected.

The pieces 7 and 8, 8 shown at Fig. 15 may have any other sha e; they may be short pieces of Wire or the ike. i of weldable metal may be employed for filling u the gap Z. The essential point is, thattie piece is or the pieces are placed or inserted in the gap Z and subjected to the jet of oxyhydrogen. In Fig. 16 the weld is plied for i Also a single piece shown as somewhat irregular in order to better illustrate the method. A skilled operator may be able to produce in this manner a nice and regular weld.l This method of welding the said crossing points presents the advantage, that the welding can e effected rapidly and in a simple manner.

Where so preferred, of course the whole joint between the crossing pieces 1 and 2, that is to say the joint running from the point a in Fig. 4 downwards round the piece 2 and upwards to the joint e may be completely welded, and in themanner that the upper parts of the joint are welded as just described above and the lower parts are welded similarly.

The method may be varied without departing from the spirit of my invention.' It is o tional in what order the several operations described should be conducted. For bending each cut out internal piece 1 may be heated wholly or partly or only on the places where the gaps g are to be formed. The projecting ends ZL ZL shown in Figs. 1a and 6 may be so treated with the jet of oxyhydrogen as to make them flush' with the vertical outside of the pieces 3 or 4. The internal frame pieces 1, 2 may have any other cross section and also the external frame pieces 3, 4.*

T claim:

A metal window frame comprising four external pieces having their ends beveled ofi' and welded together, said external pieces having holes therein for the reception of the ends of the internal pieces, a number of inn ternal pieces disposed in one direction, and having openings therein of a shape corresponding to the cross sectional shape of the internal pieces, and other internal pieces extending at right angles to the first nientioned internal pieces, andpassing through said openings, the ends of all of said internal pieces being welded into openings in the external pieces.l
