REINFOR-GING CONCRETE.

Specification of Letters Patent.

Patented Julyll, 1911.

Application filed July 13, 1910. Serial No. 571396.-

\ To all whom it may concern;

' Be it known that I, GEORGE S. GALLAGHER,

. a citizen of the United, States, residing at Concrete, of which the borough of Manhattan, in the city,

county, and State of New York, have in-' vented an Im rovement in Reinforcing the following is a specification. I

Concrete has beenrei-nforced for varipus uses in the manufactures, and arts not only by rods of various forms, but by plate'shor sheets oflmetai of'severalconfigurations in cross section, such as alternating dove-tailed.

the elastic limit and-provide intermediate yieldingmembers between the broader portions of the metal parts in which the concrete keys are shorter than the oppositely disposed main concrete keys for the purpose of accommodating expansion and contraction and changes of form. I employ oppositely disposed metal parts each intersected by shorter integral metal parts, all receiving concrete filling as keys so that in the finished reinforced concrete block, form or structure, there are oppositely disposed series of main similar concrete keys and similar intermediate and shorter concrete keys all meshing-into thenconcrete block,

the parts of :.which come at. opposite sides of the metal strip.

The metal reinforcing strip of my. invention comprises in cross section series of reversed ogees with intermediate loops; the

'ogees crossing imaginary planes at right angles to the plane (if the plateorjstrlp.

The metal reinforcing strip or plate is preferably covered with tar, asphaltum, or similar moisture-proof material and treated to a layer or coating of cork or other noneonducting material caused to adhere thereto by the tar or similar moisture-proof ma terial as the same dries. The strip orplate;

from the other side 0 thus preferably prepared"beforei being embedded in the concrete, andinoisture,

heat, and cold are thuskept from passing either way through the concrete,.'all .of=

which is hereinafter more 1;;articularly v de-.

scribed. 1

In the drawing, Figure 1 is a cross section representing the metal reinforcing strip of my invention as embedded in a body or thickness of. concrete, and Fig. 2 is an illus tration or diagrammatic perspective shoW-' 1 mg a length of the metal reinforcedstrip of my lnvention as embodied in a body of concrete.

My invention consists essentially .the metal remforcmg strip whether the same is given a layer or coating of a moisture-pr'oof material or not. v I I The longer members of the metal strip or plate constitute reversed ogees a a These are so placed as to cross imaginary planes at right angles to the side planes of the plate or strip, consequently the opposite ends of the pairs of ogees come near to-.

gether, and b 6 represent intermediate 'oppositely disposedloops which come between the spread or distantly spaced apart ends of the'reversed ogees a a and the curved portions of said ogees and the loop members merge into one another as a continuous line or member.

All the spaces between the curved parts of my improved metal strip or plate are to be-filled in solid with concrete;- the metal strip or plate reinforcing the concrete. It is therefore apparent that there is a concrete I body e or part extending outward from one surface of the metal strip or plate and a corresponding'ooncrete art 6 extending out plate and these concrete-parts or faces may have placed thereon a finished coat 6? of specially prepared-plaster or other suitable material.

From the each side of the metal strip or plate isprovided with large keys 2 and small vkeys 3,

the metal strip or illustration and description v far, it will appear that the concretebody at and the large keys are provided with auxiliary branches 4' extending as arms oflthe keys 6 e. to the opposite ends or portions of the metal strip or plate. This Inetalstrip' or plate is exceedingly flexible and may be caused to bend with readiness out of a straight line and to assume a circular or elliptical configuration, or 'a configuration in which the strip is bent with members almost at right angles to one another; the flexibility of the strip permitting the same to bend wlthout opening up sufficiently or even closing up sufliciently to destroy the key feature be applied in one or more coats so as to render the ,metal substantially moistureproof; and while this tar, asphaltum, or similar material is moist and tacky I prefer to add upon the surface thereof finely ground cork, or other non-conducting material, as a layer of suitable thickness which in the drawin Fig. 1, is shown at (Z. This enhances the eiiiciency of the non-conducting surfacing as this is applied to the-metal strip or plate after applying the far or other suitable material and' is allowed to dry and thoroughly harden before the same is em bedded in the concrete. These materials render the concrete moisture-proof on the one side and as against the influences of telnperature and moisture on the other.

While I have shown and'prefer to employ the layer or coating of tar, asphaltum, or similar suitable material and the cork or other non-conducting material, I do not limit my invention to the employment of eitheror both of these materials.

- I claim as my invention:

1. A continuous reinforcing strip of metal for concrete'f'of suitable material, comprising series of reversed ogees with intermediate and oppositely disposed integral loops and the ogees extending through planes at right angles to the longitudinal plane of the strip.

2. A reinforcing strip for concrete of suitable material, comprising reversed ogees with intermediate and oppositely disposed integral loops and a layer or coating upon each side of the metal plate or strip of a moisture-proof material.

3. A reinforcing strip for concrete of suitable material, comprising reversed ogees wit-h intermediate and oppositely disposed integral loops and a layer or coating of a moisture-proof material applied to each face of the metal strip or plate, and a further layer or coating of a non-conducting material upon the moisture-proof material.

4. A reinforcing strip for concrete of suitable material, comprising reversed ogees so placed as to extend through and lie at right angles to the longitudinal plane of the plate or strip, with intermediate and oppositely disposed integral loops and a layer or coating of a moisture-proof material upon each side of the metal plate or strip.

Signed by me this 29th day of June 1910. GEORGE S. GALLAGHER. Witnesses:
