JOIST-H'ANGER.

SPECIFICATION forming part of Letters Patent No. 784,218, dated March '7, 1905.

Application filed September 21, 1904. Serial No; 225,352.

1'0 ail wfiom, it may concern:

Be it known that I, GEORGE LANE, a citizen of the United States,residing at Poughkeepsie, county of Dutchess, State of New York, have invented certain new and useful I mprovemen ts in Joist-Hangers, of which the following is a specification.

My invention consists in a hanger such as is now commonly employed in suspendingly supporting joists, beams, or similar bodies.

The object of my invention is a' hanger which may be cheaply manufactured from commercial bar metal and which during the process of manufacture is not subjected to any torsional strains, which will decrease the strength of the bar metal of which the hanger is made, and generally the construction of a hanger which will embody an extended base and strong supporting members shaped to lie in close contact with the vertical face and horizontal top of the body by which the hanger is supported, thereby providing means for.

firmly securing through nails or screws the hanger to such supporting-body.

The accompanying drawings will serve to illustrate my invention, in which Figures 1, 2, 3, and 4 are perspective views showing the different steps required to shape the hanger, Fig. 4 showing'the hanger in its completed condition.

The hanger as a whole consists of three members5 the bottom member, 6 theside members, and 7 the top members. To construct the hanger, a'straight piece of ordinary commercial bar metal, which may be steel or wrought-iron, is employed. Such bar metal is first bent as shown in Fig. 1th at is, the

opposite ends of the bar are turned backward, so that their inner edges 8 shall form obtuse angles to the bottom member 5. The ends of thebar are next turned downward, as shown in Fig. 2, so that the inner edges 8 shall occupy the same horizontal plane as the bottom member 5, such bends being made at points 9. The ends of the bar are then turned outward, such bends being made at points 10, so

- that the rear of the ends of the bar shall lie in the same vertical plane as the rear of the bottom member 5. The bar is then bent 'as illustrated in Fig. 3-that is, the side mem-' bers 6 are bent vertically upward at points 11, Fig. 1, and atright angles to the bottom member 5. The side members 6 are then bent at the points 12, Fig. 3, backward at right angles to the side members 6. This completes the hanger.

It will be observed that when the hanger is finished the inner edges 8 of the side members 6 and top member 7 are parallel and at right angles to the base; further, that the back of the side members 6 lies in the same vertical plane as the rear of the bottom member 5.

It will now be understood that when the hanger is placed over abeam the top member rests upon the top of the beam and the side members against the vertical face of the beam.

13 indicates openings by which the hanger may be secured through nails or bolts to the beam.

It will be noted from the above description that in forming the hanger all of the bends which are imparted to the strip arc angular bends and that the metal is not subjected to any torsional strains, and, further, that such angular bends are so made that the side mem-. bers shall distribute the strains from the bottom member equally to the top member.

Having thus described my invention, I claim 1. A joist-hanger formed of a single piece of bar metal shaped to form a bottom member, side members having their lower ends disposed in parallel planes at right angles to the bottom member, their middle portions bent to form two-angular surfaces, one inclined backward'and increasing in width from below upward, and the other inclined outward and decreasing in width from below upward, and their upper ends disposed in the vertical plane occupied by the rear of the bottom member, and horizontallydisposed top members.

2. A joist-hanger formed of a single piece of bar metal shaped to form a bottom member, horizontally-disposed top members, and

side members, the upperportions of which her, and the lower portions of which bent at an angle, their fronts decreasing in Width from the vertical portions of the side members toward the bottom member and their sides decreasing in width from the bottom member toward the vertical portions of the side members.

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

GEORGE LANE.
