UNITED STATES PATENT OFFICE JOHN N. HELTZEL, OF WARREN, OHIO BRIDGING Application filed July 2, 1927.V Serial No. 203,110.

The present invention relates to bridging oblique lines 12 whose ends extend to the :for wood and metal joists, concrete forms opposite edges of the blank, with the inner and other spaced members, and aims to proend portions of the lines 12 in overlapping vide such bridging composed of novel and relation. The portions of' the blank beyond improved braces which are capable of withthe lines 12 are bent at right angles to the in- 55 standing both compression and tensile strains. termediate portion 13 between the lines 12. Another object of the invention is the protoward the same side. This produces` as seen vision of sucli braces formed from bars'or in Fig. 3, the web 13 tapering to its enes, strips of sheet metal in a novel manner, so and the flanges 14 extending toward the same as to be inexpensive as well as'practical and side from the web and increasing in width 60 ellicieiit. toward their opposite ends` with the inner A further object is the provision of end portions of the flanges 12in overlapping bridging comprising crossed and pivoted relation.

The construction and arrangement of' parts, as flanges 14 having their inner end portions in hereinafter described and claimed, it being overlapping relation will strengthen the 70 understood that changes can be made within brace at its central point. The brace has the the scope of what is claimed, without deflat terminal portions 15 extending beyond parting from the spirit of the invention. the ends of the flanges 14 or forming exten- Tlie invention is illustrated in the accomsions of said flanges, and the flanges 14 have panying drawing, whereinlugs 16 struck therefrom at the ends of the 75 Figure 1 is a perspective view illustrating web 1 3.

Fig. 6 illustrates the bridges as used for spacing the side boards or wall members 19c of a concrete form or similar structure` the I terminal portions 15c of the braces extending across the edges of the boards or members and being bent so as to hold said boards or members in relative spaced position.

Fig. 7 illustrates the terminal portion 15d overlapping the abutting end portions of two alining joists, with a pair of lugs 16, one

engaging each joist, so that the bridge may serve as a joint for connecting the joists or maintaining them in alinement.

Having thus described the invention, what is claimed as new is zl. A brace comprising flanges and a web between them, with the bends between the flanges and web arranged obliquely of the brace, and the inner .ends of the flanges being arranged close together. v

9: A brace comprising an elongated sheet metal blank bent on oblique lines extending to the opposite edges of the blank, and having a web between said lines decreasing in width from its intermediate portion to its ends, and having flanges beyond saidlines and increasing in width from the intermediate portion of the web to the ends of 'said' web, and terminal portions extending from the opposite ends ofsaid flanges beyond the ends of' the web. l

10. A brace comprising an elongated sheet metal blank bent on oblique lines extending to the opposite edges ofthe blank, and having a web between said lines decreasing in width from its intermediate ortion to its ends, and having flanges beyon said lines and increasing in width from the intermediate ortion of the web to the ends of said we and terminal portions extending from the opposite ends of Said flanges beyond the ends of the web, said flanges having lugs at the ends of the web.

11. A brace formed from an elongated metal blank of substantially uniform width and bent along substantially parallel obilque lines to provide a web decreasing in width from its intermediate portion toward the lll llt

ends of the blank and flanges increasing in width from the intermediate portionof the web to the opposite ends thereof.

12.

A bridge of the character described comprising a pair of braces each comprising flanges and a web between them, with the bends between the flanges and web arranged obliquely of the brace and the inner j ends of the flanges being arranged close together, the webs of the braces being pivoted together at the inner ends of the flanges, and said flanges having lugs near the ends of the Webs to engage spaced members, said flanges having bendable terminal portions projecting beyond said lugs.

14. A bridge of the character described comprising a pair of braces each comprising flanges and a web between them, with the o bends between the flanges and web arranged obliquely of the brace and the inner ends of the flanges being arranged close togther, the webs of the braces being pivoted to ether at the inner ends of the flanges, said anges ;5 having portions at the ends of the webs to engage spaced members to receive both cOmpression and tension forces.

15. A brace comprising flanges and a web between them, with the bends between the :o flanges and web arranged obliquely of the brace, and the inner endsof the flanges being arranged close together, said flanges havinfr lugsat the ends of the web to engagespaced members, and said langes having bendable is terminal portions projecting beyond said lugs.

In testimony whereof I hereunto ailiX my' signature.
