REINFORCING DEVICE FOR CONCRETE CONSTRUCTION.

Specification of Letters Patent.

Patented. Jan. 23, 1906.

Application filed October 21', 1904. Serial No. 229,361.

To all whom it may concern: Be it known that I, GEORGE L, PIZABODY, a

citizen of the United States, residing at Pitts.-

- burg, in the county of Allegheny and State of Pennsrlvania, have invented certain new and useful Improvements in Reinforcing Devices for Concrete Constructions, of which the follov. ing is a specification, reference being had therein to the accompanying draw-- ings, forming part of this specification, in whic'h.

Figure 1 is a longitudinal sectional view of a portionof a concrete'structure provided with my improved reinforcin device, Fig. 2 is a similar sectional view oi the device detached, showing an increasci 1 number of horizontally-disposed intervening arms. Fig, 3 1s a' plan view of Fig; 1, showing a portion of the device. Fig. 4 is'an enlarged detail view, in sectional elevation, indicated by the line I" IV of Fig. 3. Fig. 5 is a plan view illustrating a modification as to the form of the arms. Fig. 6 is an enlarged sectional detail view showing the form of arms of Fig. 5.

My invention relates to improvements in devices for incorporation withconcrete structures, as bridges, ceilings, floors, &c. and it has fd'rits object to strengthen and reinforce the concrete body portion constituting the floor, &c embedded therein and provided with pro ectmg arms or branches arranged at any angle desired and seconstructed as to be adjusted to suit the requirements of use and to make and maintain a strong bindin hold n the cement or concrete at closely-ad acent intervals.

The invention is designed to provide a reinforcing devicewhich will be capable of incorporation with the concrete in such a manstrengthgiving qualities of metallic nettmg-as, for instance, of woven wire orany other similar H1tt6T1Etl-COIlSt-lblll31llg a webbing or sheet-like base, with which I have combined or, connected holding arms; or

\ branches designed to project'atvarying angles from the webbing and to provide means or reihforc' or strengthening the concrete structure in p anes above or below the olane ofthe web. These supplemental ho dingarms are ti htly connected with the body portion of t e webbingfar'e arranged sufii-.

ciently close together to provide a suillcient number of arms to traverse or cross the probable line of fracture at two or more points in the thickness of the concrete, and to thus counteract the tendency to breakage or cleavage at all points.

Referring now to the drawings, 2 represents the cross-bar elements of the netting or other fabric or material employed as the base or body portion of the strengthening device, consisting of wires or bars crossed upon each other and connected in any suitable manner, as by knotting or welding, and which may be of any length or width desired, according to the dimensions of the concrete structure with which it is to be incorporated. Ti htly "secured upon these cross-wires, general y in one direction only, but in both directions if desired-that is, lengthwise and crosswise are a series of arms 3, consisting of wires or rods having their ends wound around wires 2 or tightly connected with them ill filly, other suitable or desired manner. It will be understood that strips of sheet metal, bars, or any other similar or suitable construction or device may be employed in place of these arms 3 and that they may be formed in any suitable design as, for instance, in corrugated form turned at their endsor provided with holding-perforations or anchoring elements of any suitable type adapted to engage and bind in and with the concrete body. As shown in the drawings, it will be seen that the arms 3 are located sufhciently close together and are of su'llicient length to cross the probable line of fracture a a, Fig. 1, attwo or more points. These arms may be erected at each end of the base, as shown in 1, the intervening arms being allowed to conform to the plane of the web to strengthen 9 5 its horizontal tension,or they may be erected across the entire area, as desired.-.

In Fi s. 5 and 6 I have shown the arms 3 as merefy single rods or wires, which may be strai ht, as shown, or bent, curved, or corrugated in any suitable or desired manner.

It will be readily understood that the proportions, sizes, number, and arrangement of ,theelements are not herein specifically provided for or limited in any manner whatever, but that these features of the invention and of its construction and application are to be considered as more particularly within the province'of the designing engineer or skilled mechanic and that all such changes and va- ITO scope sembled with the network of the base at the and the arms may be bent up at the factory place of incorporation with the building. is placed in the body of the concrete as the same is made in the of building, care being taken to bend the arms 3 to the desired angle, where they will be held by their connection with the frame 3 andwill become surrounded by the concrete and remain embedded therein.

The advantages of a device of this kind are well understood and appreciated, and my invention provides a simple, strong, cheap, and etlicient means for the purpose and is Well adapted to the objects in view.

Having described my invei'ition, what I claim is 1. A reinforcing device for concrete, &c., consisting of a flat web-like base having main and cross strands, and holding-arms connected therewith by winding their extreniities around the strands of the base, substantially as set forth.

2. A reinforcing device for concrete, &c., consisting of. a flat web-like base having main and cross strands, and looped holdingmold or in the operation arms attached thereto and adapted to be set 1 at varving angles, substantially as set forth.

3. A reinforcing device for concrete, &c., consisting of a flat web-like base having main and cross strands, and holdingarms attached thereto arranged to be bent in oppositely-disposed upwardly and .outwardly slanting directions, substantially as set forth. for concrete, &c., like base having consisting of a flat webniain and cross strands, and holding arms.

I 4. A reinforcing device I l I attached to the main and cross strands and adapted to be bent in relativel I and at varying angles to the base, substantially as set forth.

5. A reinforcing device for concrete, &c., consisting of a flat web-like base having main and cross strands, and looped holding arms having their extremities secured to the main and cross strands and adapted to be bent in relatively cross planes and at various angles to the base, substantially as set forth.

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