JOSEPH SNOWBALL, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO NATIONAL FIRE PROOFING COMPANY, OF PITTSBURG, PENNSYL- VANIA, A CORPORATION OF PENNSYLVANIA.
METAL RElNFORCEMENT FOR CONCRETE BEAMS 0R OTHER CONCRETE STRUCTURES.
' Specification of Letters Patent.
Patented July L7, 1906.
Application filed November 6, was. seen No. 285,957.
To all) whom it may concern: Be it known that I, J OSEPH SNOWBALL, of Plttsburg, Allegheny county, Pennsylvania,
have invented a new and useful Metal Relhforcement for Concrete Beams and other Concrete Structures, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, inv
inforcement therein. a
The invention is designed to provide'a reinforcement for concrete beams and other concrete structures which can be readily and cheaply manufactured, in which the supplemental reinforcing members or stirrups carried by the longitudinal or tension member may be placed as thickly together as the stresses to which the structure is subject may require and may also be distributed in accordance with such stresses, and in which special securing or holding means for retainin the stirrups in place are not required.
ith these objects in view my invention consists in a metal reinforcement composed of a longitudinal member of angular'l.cross section and a plurality of supplemental members adapted to be placed thereon and moved freely to any desired position and to remain in such position by reason of the nature of their engagement with and bearing upon the bar without other retaining or holdingvlmeans.
, y invention also consists in the novel construction of the supplemental members or stirrups hereinafter particularly described, and pointed out in the claims.
. In the drawings, 2 is the longitudinal mem- .ber, com rising a bar of angular cross-section, preferably rectangular. 3 designates the supplemental members or stirrups. these is formed from an integral piece of metal bent and doubled upon itself, with its intermediate portion formed into an eye or loop 4, corresponding) in angularshape tothe cross-section of the ar 2, on which itis ar ranged to slide. .Where the two arms of the stirrup leave the eye or loop 4, they are given means.
Each of ber,
. the longitudinal member and consisting each a quarter-twist and are also bent obliquely to the eye or loop, usually to an angle of approximately forty-five degrees. The two arms are also preferab y made to diverge from each other somewhat, as shown.
In assembling the device the bar 2 is turned cornerwise, so that its faces form inclined planes and its angles a, b, and c are presented to the corresponding angles of the eyes or loops 4, while its angle (1 projects bewhere those arms leave said eye and at the point where they are twisted, in the manner described. The stirrups may be moved freely on the bar as they are strung thereon; but by reason of their described engagement therewith it will be readily seen that they grasp or bite it, particularly when subjected to stresses, in such a manner that they are retained in the positions to which they are set without auxiliary holding or retaining They can therefore be quickly placed upon the bar and may be distributed equally or unequally thereon and as closely together .as the nature of its load may determine.
5, Fig. 3, designates a concrete'beam or other concrete structure in which the reine forcement is embedded in use, with the members 3 extending into the area of compression in position to receive compressionand. shearing stresses. p I
The advantages 'of my invention result from the facility with which the supplemental reinforcing members may be placed and distributed upon the longitudinal member and from the comparative 'cheapness with which the parts can be manufactured.
The cross-sectional form of the bar 2 may be changed, with corresponding changes in the members 3, without departing from my invention, since What I claim is- 1. A metal reinforcement for concrete structures, comprising a longitudinal memand supplemental members strung upon of two diver ent load-carrying arms inclined to the axis 0 the lon itudinal member in the direction of the len th thereof,'and united by an integral eye or oop which has a bearing upon both the up er and the lower surfaces 0 the said bar 5 en stantially as described the structure and v tween the diverging arms of the stirrups,
2.. A metal reinforcement for concrete structures, comprising a longitudinal member of angular cross-section, and supplemental members consisting each of an integral flat metal piece bent upon itself to form a substantially closed angular eye or loop with divergent arms extending obliquely therefrom in the direction of the length of the longitu-' dinal member, the eye or loop having a bear ing upon both the upper and the lower surfaces of said member, said longitudinal member having unobstructed surfaces whereby the supplemental members-may be moved freely thereon when not loaded; substantially as described.
3. A reinforcing member, consisting of a piece of fiat metal bent upon itself to form an intermediate loop or'eye, with obliquely-exmy hand. v
