BUILDING CONSTRUCTION.

Specincation of Letters Patent.

Application led August 23, 1915. Serial No. 46,799.

1 0 am lLa/1.0m t may concern Be it linown that I, JULIUs KAHN, a citi- .ien of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Building Construction, of which the following is a specification.

This invention relates to a metal frame for a building, and among its impo-rtant features are the following: means whereby two structural metal sections, one of which has a plurality of rows of spaced transverse slots, may be assembled and securely braced with respect to each other at points corresponding to any desired pair of transverse slots by a wedge connection, whereby the use of rivets or bolts is avoided; means whereby a third structural metal section of less dimension than the others may be connected to the two first mentioned sections by wedge means, the three\sections mentioned preferably constituting the first story stud, cap plate and second story stud; and means whereby bolts may be readilyA substituted for the wedges if desired.

The invention also consists in the details of construction shown, described and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective View of a preferred vembodiment of the invention. Fig. 2is a vertical section through the cap plate and adjacent parts. Fig. 3 is an elevation of a floor beam and adjacent joists wherein the invention is also embodied.

Similar reference characters refer to like parts throughout the several views.

Under the ordinary base wall l is mounted a sill 2, preferably of I pressed metal, in which are formed on opposite sides of the longitudinal center parallel rows of alined transverse slots 3, each ofwhich preferably includes the circular or enlarged mid-portion, 4. The sill may be of Z.section, in which case one flange 5 i's placed so as to engage the inner surface of the wall, the other flange 8 being extended upwardly in the plane of the outer wall surface. Rising from the sill is the stud (of substantially the same transverse width as the sill) that includes the web 12, the side flanges 13 and, preferably, the in-turned edge flanges 14, the latter of which not only stiffenthe stud but engage the sill to insure a proper bear- The stud has struck therefrom near 'its ends rows of transversely alined stirrups 15, the spacing of which corresponds to that of the rows of slots in the sill, and is perforated between the stirrups of each row for a purpose hereinafter indicated. Flat metal connectors having ends extending longitudinally beneath the sill also have Shanks 2l that pass through corresponding slots of each row and upwardly between the pairs of stirrups and the web of `lthe stud; these Shanks are perforated between the stirrups of each row, and a two-armed wedge 24 (one arm 25 of which is sharpened and bites into the upper surface of the sill, the other arm being tapered) is driven through the perforation in the stud and through that in the shank of the connector. These perforations are so located as to allow the wedge to draw the connector firmly into engagement with the lower face of the sill, or, in other words, so as to draw the sill and the stud together. When the parts are thus joined, the arms 25, together with the web of the` stud and the in-turned flanges 14, form a broad bearing and prevent the stud from swinging longitudinally on the sill in one direction, and also afford a very rigid joint as concerns lateral swinging stresses; and the ends 20 stifen the stud against swinging longitudinally in the reverse direction.

The studs 12-13-14 (but one of which is shown) extend from the sill to the next story of the building and are there surmounted by the longitudinal cap 26 (pref- `erably of channel cross-section) having down-turned anges 27 that embrace the sides of the studs. The cap is also provided With rows of transverse slots 3-4 that correspond to the slots in the sill. At the upper ends the studs are perforated and have stirrups 15; and a connector 2021, that passes through one of the slots'3, is .secured in position by a wedge 24, the construction and purpose of these elements being the same as previously described with reference to the joints between the stud and the sill.

Rising from the cap in alinement with the outer side of the stud 12-13-14 is a second story stud of vless transverse depth than the former that includesthe web 29,

vside flanges and (preferably) the inturned edge flanges 31. The second story stud is provided with a single row of stirrups 15 and a flat metal connector 32, that Patented July a5, 1916.

plate is secured in position by bolts 36.A

Other uses are obvious-for example, the connectors may have their ends 20 placed above the sill and bolted thereto directly through the holes 4. It will be understood, of course, that the provision of the series of slots allows the studs to be located at practically any desired spacing along the sill.

rIhe invention is also applicable to floor beam and joist connections. In Fig. 3 a floor beam formed of two pressed channel sections riveted together baclg to back, supports on one side a pressed channel joist 4l of a given depth and on the opposite side an opposed pressed channel joist 42 of lesser (preferably half) depth. The floor beam is provided with two rows of slots (not shown) corresponding to the slots 3-4, through the upper ofwhich passes a connector 32 that serves to join the two joists, and through the lower of which passes a connector 20-21. 'Two armed wedges 24 clamp the parts together as in thecase of the studs and cap plate.

It is clear that the arrangement of the members is subject to Wide Variation, and the present illustrations are to be taken, therefore, as diagrammatic.l Consequently, I do not wish to be limited otherwise than as indicated by the subjoined claims.

I claim l. In a building structure, a metal bar lhavingtwo transversely alined spaced stirrups near one of its ends, a second metal bar extending across the end of the frstjbar, said second Lbar having a pair of transversely alined transverse slots spaced from each other to correspond to the spacing of the stirrups, a third metal bar alined with theirstbar and engaging the second bar from the opposite side, said third bar having a transverse stirrup near its end, a pair of (connectors, one passing through one of the stirrups on the first bar afnd one of the slots in the second bar, the other passing through the second stirrup `on the first bar, through the second slot 1n 4the second bar and through the stirrup on the third bar, land wedges. engaging the connectors for clampingthe parts together.
