Application filed. October 26, 1912. Serial No. 727,836.

To all whom it may concern:

Be it known that I, JOHN A. JONES, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Metallic Window-Sashes, of which the following is a specification.

This invention relates to metallic frames, such for example as window sashes, and-particularly to frames which are formed of separate intersecting members.

shows a tongue, which forms a detail of my 1 invention, in the position it occupies during the'operation of assembling the members. Fig. 4 is a fragmental perspective view of a slotted member on which a tongue is formed and which forms a detail of my invention. Fig. 5 is a fragmental perspective view of a notched member which cooperates with the slotted membershown in Fig. 4. Fig. 6 is a fragmental perspective view of the members shown in Figs. 4 and 5 in positions they occupy during the assembling operation, prior to securing them'toge'ther, Figs. 6, 3, and 2, respectively, illustrate three successive steps in the operation of assembling and securing two intersecting members to- I gether in accordance with my invention.

In carrying out my invention I provide a slot in one member through which the cooperating intersecting member is inserted and in which it is locked by means of a .i tongue which projects partially across the slot.

In the drawings I have shown my invention as applied to T-bars, but I deslre it to be understood that the invention may be ema ployed," with equal success with channel irons, angle irons or other standard sections and that I do not limit myself to sections of any form or shape.

As illustrated, the web 8 of one member, which for convenience of description I will term the vertical member 9, is provided with a slot 11 and a tongue 12, which, as shown, is struckfrom the metal of the web and is so formed that it projects partially across the slot 11, but is capable of being bent at an angle to the web 8 for the purpose of uncovefing or clearing the passage through the s 0t.

The cooperating member, which for convenience of description I will term the horizontal member 13, is adapted to project through the slot 11, inthe member 9, and is notched at 1 1 and 15, as illustrated in Fig. 5. The notch 14 is formed in the edge of the web portion 16 of the member 13, for the purpose of engaging an edge of the slot 11 in the member 9, when the members are assembled in their normal positions, and it is substantially of the same width as the web 8. The notch 15 is formed in the head portion of the member 18, extends to the inner edge of the web 16, and is adapted to receive the head portion of the-member 9, when the member 13 is in the normal position with relation to the member-9.

The slot 11 is so formed that it is capable of permitting the horizontal member to be passed through it when the tongue 12 is moved to the unusual position; that is, when the tongue 12 is bent at right angles to the web 8. In the illustrated embodiment this is accomplished by so forming the slot 11 that it extendslongitudinally'of the web 8 and is provided with an off-set 17, which extends from the slot inwardly-to the head portion of the member 9, and produces a substantially L-shaped slot in the web, one portion 11 of which is wide and extends longitudinallv of the web and the other portion 17 of which is narrow and'extends transversely of the web. The Off-set l'? is substantially the same width as the thickness of the web 16, of the member 13, and the corner or shoulder formed between it and the slot 11 is rounded for a purpose which will hereinafter be described- The length of the slot 11 is a little greater than the combined width of the web 16 and the thickness ofsthe headportionof the member 13. The

; of the member 8.

tongue 12 is so formed that it extends longitudinally of the slot 11, when it is in the normal position, and it is of such length .that.the distance between its free end and theopposite edge 18 of the slot 11, is substantially equal to the thickness of the web of the horizontal member. r

The operation of assembling the horizontal and Vertical members is as follows: The tongue 12 is bent to a position substantially at right angles to the web 8, the horizontal notch 15 is located directly opposite to the head portion of the member 9. The member 13 is then turned or tilted so that its web is moved to a position at right angles to the head portion of the member 9 and into contact Withv the edge 18 of the slot 11. In turn- .ing the member 13 to this position the inner or severed edge of its web 16 moves intothe off-set 17 of the slot 11, its notch 14 moves into engagement with the upper edge of the slot 11, and the edges of its notch 15 engage the edges of the head portion of the member 9. The shoulder formed between the slot 11 and the off-set is rounded for the purpose of aiding in tilting themember 13 to its normal position, and the severed edge of the web 16 of the member 13 may also be notched or rounded for the purpose of causingthe web to more easily enter the ofi-set 17 After them'ember 13 is in the position illustrated in Fig. 3, the tongue 12 is bent inwardly .or back to its normal position, so that its lateral faces are flush with the faces o-fthe web 8, and so that its free end engages the adjacent face of the web portion 4 16' of the member 13. This positively locks the members 9 and 13 together, since the tongue 12 prevents the member 13 from being tilted'in the slot '11 and the notches 14 and'15-positively engage the member 9 and it cannotbe releasedtherefrom except by tilting the member 13. 1 I

It will be understood'that the olf-set 17 of the slot 11 may be dispensed with by providing a notch in the severed or inner edge of the web 160i the member 13, as shown ber 13, will rest upon the'head portion of the member 8 instead" of being notched out,

as illustrated. Such a construction reduces the width of the notch 14, shown in Figs. 5 and 6 to the width of the web 8 of the member 9. When this construction is employed the notch 13 must be increased in depth to accommodate the tilting operation, since the member 13 will turn about the edge of one of the flanges of its head portion during the tilting operation, instead of turning about the inner or severed edge of its web portion 16.

In forming a window sash or frame portion, with the members illustrated, each horizontal member 13 is provided with as many sets of notches 14 and 15 as there are vertical members 9 in the frame or sash; and each "ertical member is provided with as many slots 11 and cooperating tongues 12 as there are horizontal members in the frame or sash. The vertical members are then located in parallel relation to each other and the horizontal members are tilted relatively to the vertical members, as shown in Fig. 6 and are inserted through the slots 11 to such positions that each set of notches 14 and 15 is located opposite to a vertical member. Each horizontal member is then turned, relatively to the vertical members, to the position shown in Fig. 3 and the tongues 12 are then bent inwardly so that their inner edges engage the webs 16 of the horizontal members, as shown in Figs. 1 and 2. This locks the members together and forms a permanent frame or sash. By properly proportioning the width of the notches 14 and 15 to the webs and headportions of the member 9, and by properly proportioning the length of the tongues 12, so that they firmly press the webs, engaged by them, into contact with the edges 18 of the slots 11, the joints between the horizontal and vertical members will be absolutely rigid and there will be no relative motion between the members.

While I have illustrated my invention in connection with a metal frame or window sash, I desire it to be understood that my invention may be employed in looking any two intersecting metal members together and that various changes, substitutions, omissions, additions and variations may be made in the apparatus illustrated without departing from the spirit and scope of my invention as set forth in the appended claims.

What I claim is:

1. In an interlocking joint for bars, a bar having an L-shaped eye therein, a single tongue formed from the material removed from said L-shaped eye, a second bar having a width substantially equal to the length of the eye of the first bar, said second bar having oppositely disposed notches leaving an, unnotched portion of the bar intermediate its marginal notches, substantially equal,

to the width of the offset portion of the L-' shaped eye of the first bar through which the second bar is adapted to be thrust and interlocked therewith by a partial rotation, in which position it is secured by the return of the single tongue to the plane of the web.

2. In an interlocking joint for bars, a flanged bar having an L-shaped opening confined to the web portion thereof, a second bar having oppositely disposed marginal notches extended through the opening of the first bar and engaged therewith by a partial rotation, the second bar being seated against the terminal wall of the oliset portion of the L-shaped opening, and means for locking the bar in its adjusted position.

3. In an interlocking joint for bars, a

flanged bar having a longitudinally disposed substantially L-shaped opening confined to the web portion thereof, a second bar having oppositely disposed marginal notches extending through the opening of the first bar and interengaged in the offset portion thereof by a partial rotation, said second bar extending in opposite directions beyond the transverse limits of the offset portion of the opening, and means for retaining the bar in position.

In testimony whereof, I have hereunto subscribed my name this 24th day of October, 1912.
