To all 'it may c onceraf- Be it 'known that I, DANIEL Indianapolis, in the county of Marionind State of Indiana, haveinvented certainnew and useful improvements 'in Reinforced.

Structures, owhich theifollowing is a speci- -iicat-io'n. j

This. invention relates to, im rovements in the. construction of walls, colliimns, beams,

lmee braces, and thelke, employedin building structures'of various'sorts, my invention -being more particularly,' although not exclusively, designed 'for vsuchf-membersv when used as parts of'- buildings, bridges, sewers, etc., which Iare commonly constructed `of concrete or other masonry; land the. inven- .n `To theseand other endsmy sists, in general, in a wall ,or column, and

beam structure principally characterized'by forcing members 'so disposed as to bond the structure in, all directions in which it may tion has .for its general-object to provide an improved structural member'of the class an for the purposeV above mentioned, char-l and' capacityto resist the various-strains to which it may be.v 'subjected in any and all-. directions, together with eater economy in 'respect to cost of materia s and construction ascompared with similar structurat-,presinvention con# vthe incorporation therein of tension or reinbe subjected to strains.,

yAs -above stated, my invention has tol do with wall, or column, and beam structures ofconcrete and 'generally similar materials I 'and contemplates thestrengthening and restrains existing 1n inforcement of such structures in a comparatively Simp e fand inexpensive manner by embedding therein a series ofI tension or reinforcing rods so disposed yas to resist thedirection of anyor--all of the'dimensions of the structure.v In ithe accompanying drawing I have illustrated `severa 'with tension membfrs" disposed in a variety of relations tosecure effective resistance to disruptivestrains occurring longitudinally,

crosswise and widthwise of th and referring thereto Figurel shows vertical and .horizontal members provided with tension rods disposed; in' accordance uwith the principles `of my invention. Ifig. i12, i'saverticlal sectional view of asimilar;y

The extension of one of the' rods 21 throu h the shearing re 'on as at22 and thence a ong the upper sur ace -at 26 andthence across to the opposite face of thel column as at 32 results inthe one reinforcin member "passing continuously through 'aV Ytheregions of tension inthe two members.

members securely at their junction;

But v by arranging the rods or members in a heliX'or spiral as shown at llwvherein they not only pass back andforth from one face' to the other of the Wall or column but also extend widthwise or' the latter and are in-.

terlooped as shown at'lithe material is Ialso bonded in the widthwise direction, making it sc cure lagainst. cracking or bursting in all tlnee'dimensions.
