Wmmmm'" I v mmmummnmnw l2 (\b x auvento'z UNITED STTES EAEEN orrion EBNEST W. GOODEY, F PHILADELPHIA, PENNSYLVANIA"- JOINT FOR ROLLED METAL BARS To all whom it may concern:-

Be itknown" that I, Ennns'r W. GOODEY,

a citizen of the United States, residing at Philadelphia, in the-county of Philadelphia and State of Pennsylvania,'have invented certain new and useful. Improvements in "Joints for Rolled Metal Bars, of which the following is a specification.

Y My invention relates to improvements in joints for rolled metal bars, the object of the invention being to so construct intersecting bars of a metal frame that they may be com- 'pletely interlocked and without cutting entirely through either of the members.

A further object is to provide an improved joint which enables a strong interlock between the bars'of a frame at right angles to each other, and which is especially adapted for use in connection with window, skylight, and other glass structural work.

\Vith these and otherobjects in view, the

' invention consists .in certain novel features ofconstruction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims;

In the accompanying drawings: Figiire 1,

is 'a fragmentary view in side elevation illus trating the bar 1 of my improved joint. Fig. 2,.is a similar view of the other bar 2. Fig. 3, illustrates incross section the bars shown in Figs. '1 and 2. Fig. 4c, is a view in elevation of bar 1, showing it as it is shaped to receive the bar 2, the latter being shown in section. Fig..5, is a view in section on the'line 55 of'Fig. 4:. Fig 6, is

a view similar to Fig. 4, but showing the joint as itis completed, and Fig. 7, is a perspective View of the completed joint.

While 'I shall hereinafter refer to the bar .1 as the vertical bar, and the bar 2 as the horizontal bar, these terms are used merely for c'onvemence of description, as

' they may, offcourse, be exactly reversedif- .45

desired;

The bars 1 and 2 each comprise web portions 3 having curved beads 4 attheir foras seen in-Fig. 3.

. a I y I. bar 2. The curved bead porti n 4 of r"1 is cutout forming a curved opening 7 registering with the opening 6, and ada ted to receive the rounded head portion & 0 bar 2. The web portion 3 of bar 1 is slit longitudinally as shown at 8 and 9 forming two tongues 10- and 11 at opposite sides of the opening 6'. Bar 2 is provided in its web' portion at its' free edge witlra notch 12 which is equal in length to the distance between the openings 6 and the free edge of the web portion of the bar 1. W'hen the. bars are thus formed. the tongues 10 and 11 are bent at an angle to the web of bar 1 as shown in Figs. 4 and 5. Bar 2 is then inserted through. the opening thus made, and first assumes the position shown in Figs.

4 and 5/ When in thisposition, bar 2 is given a quarter turn to bring its rounded bead portion 4 into the curved 013611115 7 and its notch 12 engages the .web portion of bar 1. When in this position, the tongues 10 and 11 are bent back to their normal po-. sition, and the parts will'be as shown in Figs. 6 and 7. That is .to say, the parts will be securely looked as they cannot move either longitudinally or laterally relative to each other. and neither of the bars will be cut entirely through.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not: limit myself to the precise details set forth, but consider my- .self at. liberty to make such changes and alterations as fairly fall within the spirit I and scope of the appended claims. 3

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

.1. The combination with twobars. both tioned bar, substantially as described.

2. The combination with-two bars, both bars having fiat .web portions and rounded beadsther'eon, one bar having a longitudinal bead. eatending'b'eyond the rounded bead and in line withthe web, said last-mew n'umed bar having 'a curved opening in its web portion of the first-mentioned bar, subroimded bead portion, a transverse Opening -stantially as described. in 117s web portipn extending" from the In testimony whereef I have'signed nay rounded- Opening to? point removed from name tq this-specification in the" presence 5 the edge of the web, said.
