UNITED STATES PATENT OFFICE.
Specification of Letteral Patent.
Patented July 17, 1906.
Application filed January 111906. Serial No. 295,681.
I To all whom it may concern.-
'citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented new and useful Improvements in` Beams, of which the following 1s a specification.
This invention is a; metallic bar particularly designed and' adapted for use as a truss to reinforce concrete structures, particularl concrete floors, beams, arches, and suc structural parts. v
The object of the invention is to form an improved beam characterized by eat strength in proportion to the Weight and aving means to hold it in place in the concrete structure.
I am aware that it is old in the 'art to use a iiat bar with arms struck up therefrom. This construction is deficient in strength to resist bending strain, lacking the necessary stiffness or resistance except by the use of heavy metal.
In my invention I provide an angle-bar of novel shape having arms struck up therefrom, as will more fully hereinafter a pear. This construction gives greater strengt and rigidity in proportion to the .weight of the miiil'h I dr F t eaccompanying awin i lis an end view of the bar or blargic ungsllildared from which the beam is made. Fig. 2 is a similar view of the beam with the arms struck up therefrom. Fig. 3 is a side view of the beam. Fig. 4 is a plan view. Fig. 5 is an end view of a modliication, the arms being struck up inopposite direction to that shown in Fig. 2.
The beam consists of a metal plate or bar rolled or otherwise shaped to an angular or form, as indicated at 6 in the drawings. At each edge of the bar the metal is oiset or rolled in a plane parallel to the base of the angle, forming wings 7, from which the arms 8 are struck up by shearin said wings with an I.'cut and bending up t e arms so formed. As shown in Fi s. 3 and 4, themiddle of the bar is preerabIy left unsheared, the arms being located at the ends and being inclined in opposite directions at each e'nd respectively. In t e form shown in Fig. 2 the arms are bent up on the side of the beam opposite the ang e. In Fig. 5 they are bent up beside the angle. -The angular construction makes a very stiff bar in proportion to the weight of the metal. v As stated, the bars as ordinarily used will be embedded in concrete, the arms 8 serving to bind tight the plastic' material to th bir to form the complete beam or girder.
- c a1m A structural metal beam an ar in crosssection and offset at each edge 1n a plane par- A allel to the base ofthe angle, and having arms sheared and struck up at its opposite side ed es from said offset portions.
testimony whereof I have signed m'y namel .to this specification in the presence of two subscribing witnesses.
