- Application filed-November 2a, 1894, sermmszasvz. (No model.)

To all whom it may concermn Be it known that I,

and, in-thecounty of 'Cuyahoga aiidState of Ohio, haveinvented certain newand useful Improvements in-Wrought-Meteil J bist-Hang ers; and I do hereby declare the following to be a full, clear, andfexact description of the -inventi.on,such the art to which itfappertains toimake and as will enable others skilled in use thesame. I

My invention relates towrought metal joist hangers; and the object of theinvention is to produce a wroughtmetaljoist hanger which shall be strong enough for the intendeduse, and,'in my opinion, stronger than'any metal joisthanger heretofore made of equal weight, and which shall also be cheaper than any wrought metal-joist hanger heretoforem'ade. The inventionconsists of the described hanger, the blank from whichit is made, and

themethod of forming saidblanks with no.

considerable waste of material.

In the drawings, Figures 1 and 2 are per:

.spective views of two forms of bars from which the hanger blanks inay be cut alternately from opposite sides. Figs. 3 and dare end views of the. bars-shown in. Figs. 1 and 2 rethrough which spectively; and Fig. 5 is a of the com'pleted'hanger.

Referring to the parts by letter, A Arepresent the two substantially parallel vertical sides of the hanger;B,the intermedia.tehorizontal shelf and O 0 represent flanges which perspective view are integral'with the rear" edges of theme I sides and lie at right angles thereto. Theseflanges extend beyond the ends of the sides and are bent backward into] planes substan- "tially atright angles to the sides themselves and-parallel to the. shelf B, thereby forming arms C C which are adapted to. lie on top of and to be secured to the beam by whichthe hanger is to be supported." "Holes c are'formed in the flanges CO and in the arms 0"(3,

I means of which the hanger may be secured to said. beam.

. the rear edge of the shelf. 5;

part of the-blank whichforms the shelf is cut isshown-in the drawings, there is In forming the hanger the realpart of that JAMEsHV N Donn, a States, residing aiFGleve pass the screws or spikes by In the preferred form, which no flange onbifiwhereby the bending of the flanges on the sides into the desired position may be effected without danger that the blank will be split vduring'said bending operation, J

When the hanger is secured to the beam, 'the flanges O, 0 lie against. the side of the beam, and thearms 0' 0 lie on top thereof; and-when the hanger is fastenedin this position by screws or nails passing through said sides and arms, iris believedthat the hanger has greater supporting strength than any hanger-ever made ofeqnal weight. By supportingithe hanger in part by the side flanges,'there is less danger than there would otherwise be thatthe arms 0' C will straighten" outT whollyfoi-tin part and thus permit-the*hangertoybe pulled loose from the beam. Another adt'antage of the connection 1 of the hanger to the beam by means of the side flanges, is that thereby all side motion of the hangers is described hangers," a joist'may be securedto a beam as firmly asjif niortised thereto, The described hanger'may be made by'cutjting blanks alternately from opposite sides 'of prevented; and through; the

sides,'-forminj"g the arms 0' .C'; and that part the blank and attached from -which the-shelf is as indicated in Figs.11

to that part thereofformed'; is cut-away,

at right angles to the body, thereby forming the flanges GO and arms 0 O;

and intermediate shelf; and' the arms are bent back 'on lines 3'-4, thus completingthe' hangers. The-bar'shjdwn in Fig. 2 is'rolled with the two edge flanges at-right; angles to ,the body or web. Thblanks are cut'out in the manner heretofore described; and the part 0 of the flange is cut on from that part of the blank which forms the shelf. When this form'of bar is used, the operation of turning the flangesat right angles to the body of the thebody, is bent on dotted lines 1 '2 toform the sides:

, G of the'saidnedge which is at the middle of p e and 2. When the blank has been cutout, the rear side is bent blank is of course dispensed with, or rather,

. said bending is done before the blanks are wrought metal bar, sections each of Which'hasi. oppositely inclined ends and unequal paralcut out.

It is advantageous to employ a bar having its sides a little thicker than the web, because thereby the hanger will be stronger.

Having described my invention, I claim:- 1. The herein described process of making blanks for joist hangers, which consists in cutting sections alternately from opposite sides of a wrought metal bar, cutting the edges of said bar away from the opposite sides of adjacent sections, and leaving the edges so cutaway from each section attached to and project-ing from the ends of the adjacent sections, substantially as and for the purpose specified.

2. The herein described process of making blanks for joist hangers, which consists in cutting, alternately, from opposite sidesof a lel sides and arms projecting from both ends of its longer side, substantially as and for the purpose specified.

3. The herein described process of forming a wrought metal joist hanger, which consists in cutting alternately from opposite sides-oi a bar, blanks having oppositely inclined ends and unequal parallel sides, and arms which project from both ends of the long side, turning the edge of the long side up at right angles to the body, cutting away the middle part 0 of said turned up edge, bending the blank to form two parallel sides and an intermediate shelf, and bending back the projecting arms, substantially as and for the purpose specified. l

In testimony whereof I atfix my signature in presence of two witnesses.
