INVENTOR ATTORNEY oists b are used to carry the floors of a build- Patented Jan. 7, 1930 UNITED STATES PATENT OFFICE 1 JOHN LAIILY, OF GREAT NECK, NEW YORK; JOSEPH A. HENLEY, JOHN LALLY, JR., AND ELLEN T. LALLY, EXECUTOBS OF SAID JOHN LALLY, DECEASED, ASSIGNORS T LALLY COLUMN 00., OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MAS- sAoHUsETTs BEAM HANGER Application filed October 8, 1927. 'Serial No. 224,901.

My invention relates to beam hangers which are carried by I-beam headers and in turn carry wooden joists in building construction and it is my object to produce a hanger which will be cheap, strong, light in weight and which will carry heavy loads without undue settling and which will be solidly held in place so that it cannot shift and which avoids boring holes in the header. A further object is to so attach the bearing plate that it cannot become lost in transit and which plate will be self-levelling when the joist is placed on it.

In the drawing Fig. 1 is a side view, partly in section, of the hanger on an I-beam header and carrying a wooden joist; Fig. 2 a detail view of a slight modification of the hanger; Fig. 3 a perspective view of the hanger of Fig. 1, Fig. 4 a view of the self-levelling bearingplate; and Fig. 5 a top view of the hanger with the plate in position thereon.

, I As is usual in certain types of building construction an I-beam header a and wooden mg. I

The hanger proper is preferably made of rolled, round stock and has a bottom bar 1, which may be flattened to increase the hearing area in contact with a wooden oist, side bars? and 3 and top bars 4 and 5. The top bars are bent downwardly at 6 and 7 and are apertured, the upper edges of the apertures being approximately alined with the lower edge of the I-beam flange. I

In use the hangers are placed over the top flanges of an I-beam header and wedges 8 are driven into apertures in the parts 6 and 7 thereby locking the hanger solidly to the I-beam. A hearing plate 9 may be laid on the bottom bar 1 and the wooden joist Z) is then dropped into place. Any tendency of the hanger to slide forwardly or tilt on the I-beam is resisted by the wedged top barswhich also resist any attempt of the hanger to work sidewise along the beam.

In Fig. 2 I have shown a slight modification in which the wedges and top bars are integral, thehook-like portion 10 being hammered or driven into locking engagement with the beam flange after the hanger has been positioned,

and 2 extend on each side with the side bars passing through the apertures, the plate resting on the bottom bar. By this construction the plate can rock slightly on the bottom bar and be self-levelling under load while it is held in place on the hanger and cannot be separated and lost in transit. It also eliminatesthe expense of welding the plate to the hanger.

By the use ofmy invention wooden joists may be used with I-beam headers. Heretofore it has been customary to use an ordinary Bethlehem beam with the joists fitted between the flanges, but to get the necessary clearances the I-beam had to be unduly heavy and expensive. By the use of my invention an I-bea1n of suitable weight and dimensions, such as the recently developedJ ones & Laughlin sections, can be employed in place of the previous expensive construction.

I claim":

1. Beam hanger construction comprising a hanger composed of a bottom bar, sidebars and top bars, the ends of the top bars being bent downwardly and perforated and adapted to lie over an I-beam header and wedges passing through the apertures and engaging the under side of the beam flange.

2. Beam hanger construction comprising a hanger composed of a bottom bar, side bars and top bars, the ends of the top bars being bent downwardly and inwardly and adapted to lie over and engage the flange of an IV-beam. and a bearing plate, apertured ears on said plate, the side bars of the hanger passing through said plate apertures, the plate resting on the bottom" bar.

In testimony whereof I have aflixed my signature.

JOHN LALLY.
