To all w/iom it may concern." l

Be it 'known that I, HENRYC. Brumes.

a citizen of the United States,.residing at Kalamazoo, in the county of Kalamazoo i5' and State of Michigan, have invented eertain new and useful improvements in Reinforcing in Concrete; and do declare the following to be a full.' clear, and exact do soription of the invention, suoli as will e:o-

able others skilled in the nrt to which it appertains to makeand use the saine.

This invention relates to reinforced oon-- crete construction, but more particularly to devices used to maintain the reinforcing material or elements in adjusted position.

Gneobject of this invention resides in providing av means to facilitate the use of Wire mesh as reinforcing materiel.

A further object of the invention is to provide e simple ineens for .reducing amount oi time and labor required in oonstructing reinforced pavements andv the lilas.

A stiil further object oi? my invention resides in designing e novel mer fn retain the letterin proper position.

Another object 1s to provide ariel.

invention consists of certain novel details of construction, combination arrangement 3% ofparts tn be more particularly .hereinafter set forth the Claim.

in constructing pavements and tile' like, it is frequently required that-they beprovided Witli reinforcing material interposed between the bese and 'Wearing course of tlie pavement. ,its the reinforcing material em-I ploved is usually in the forni of Wire ioesli which latter is sliiipedin rolls, it een loe' readily perceived wint a. diiiiouit met ter it is to properly .lav the seme, inasmuch es owing.;- roits previously it natiirallj; to iesnn ne rolled enel consequently einen inie. incl labor is required in ljing the 'wire mesh so that it will lie Y fectly let. ifoivevei', actual praetice has demonstrated 'that no matter iiow eareiiolljif 're inesii. or screeningn may be leid7 nevertiiel will bulge et 1ferions points, the resni-J oi vsliieli .is ttormntion oi cavities in tlie isa.nement structure, with the result that the iife ofthe latter is materially shortened.

Raimi,

longitudinal edges of the flattened portion are curved outwardly in opposite directions to form lwings 7, whichfproduce a spiral at this end of the body, and consequently enable the latter to be readily inserted into the concrete, as will be readily understood without further description.

From the foregoing, it will be obvious that to permanently secure a given length of Wire screen in a fixed position, the anchoring irons 2 are passed through the screen'at predetermined points thereon, and are then forced into the concrete so as to bring the fingers 6 into engagement with the wires composing the screen, which will then permanently and securely maintain the screen in a proper position. In this connection it is also to be noted that these anchoring irons may also be employed for interlocking the Various stretches of wire screening composing the reinforcement. In other words, where one screen overlaps the other, one of the anchoring irons may be driven into the concrete so as to have one of its'fingers engage one of the wires of the underlying screening, and the other finger engaging one of the wires of the overlying screen.

Although in the foregoing description I l have specifically referred to the utilization of my improved anchoring iron in connece tion wlth relntorclng-material m the form of a screening, but I do not however desire to limitmyself to this particular form of' reinforcement, inasn'luch as the fingers (i on body 3 could just as conveniently engage two ordinary reinforcing rods if the latter were arranged in parallel relationship, in a concrete mixture as the body 3 forced through the latter and between said rods would engage the same as'will be readily understood without further description.

Thus it will be seen that I have provided an extremely. .simple article which will enable a-concrete pavement using wire mesh as a' reinforcing material to be constructed with less difficulty and more efficiency.

I claim:

' An anchoring iron of the character set forth comprising a body, a plurality of spurs ar langed thereon, said body having one end bifureated, said furcations being arcaately extended in opposite directions to form lingers, and boring` means formed at the other extremity of said body substantially as and for the purpose set forth.

In testimony whereof Iihave hereunto set my hand in presence of two subscribing witnesses.
