'To cZZxwzom 'it may concern:
Be it known that I, .JAMES DUaoLnr, a citizen of the United States, residing at Bessemer, in the count;T of .Jefferson and State of Alabama, have invented new and useful .Improvements in lieinforeing-Bars for Concrete, .of which the fol-lowing is a speciiication.
The'invention relates Yto reinforcing me diums and more partiouilarl),v to the class of reinforcing bars or members for concrete and other masonry constructions.
The primary obect of the invention is, fthe provision of means, namely, these bars or members with. depressions or .hidentations therein, soarmnged that the cross sectionalarea of the said bars or members .is maintained absolutely niniform throtigfhout vthe longitudinal extent of the latter.
Another object .ofthe invention is the pr vision of a reinforcing .bar or member for concrete :and other construct-ions, having a minimum rdisplacement of the metal in the said bar or member to produce a depression or depressions with a maximum resulting gri ping area.
t is obvious with these objectsin v-iew't-be invention compnises'a particular construction of reinforcing. bar vor member having therein indentations in one 'or more pairs of faces thereof and where the'latter exist inone face the material displaced there is replaced in the adjacent face of the bar or member, which space is intermediate the indentations or depressions therein. other words by providing spaced indentations or depressions in two faces and makingA the indentations or depressions in one face stand in a position relative to the spaces intermediate the indentations or depressions in the adjacent remaining face of the bar or v member, thereby the latter is maintained at a uniform cross sectional area.
In the drawings and forming part of this specification I haveshown in detail eiective forms of the embodiment of the invention which, vto enable those skilled in the art to l perspective view of a portion of the length of one form of the bar or member. Fig. 2, is a plan view thereof. Fig. 3, is a transverse sectional view on the line 3 3 of Fig. 2.
Specification of Letters Application filed January 10, 1968.
Patented Aug. 17, T909.
Serial No. 111,122'.
tionof the invention. Fig. 7, is a transverse sectional View on the line of Fig.. P6.. Figs. S
and S), are transverse sectional views of still further niodiiicatiis, showing; slight variations in 4the formation of the Jdepressirnrs or indentntions. f
.Simi-lar reference characters indicate `corresponding parts throughout the several views in the thawings.
liiisterling to Figs. lv to 5., the numeral '2, desigrmtes a bar or member of any suitable material, though, :preferablyof metal, such as steel or iron, which is approxiniatel?,7 rec'- tangular cross section., its edges beingr preferably'rounded. In its faces 3, 3, are depressions 4, of` elongated formation, and spaced from each other a suitable distance and -disposed Within marginaledges'of the said faces 3, 3, oi the bar. It is apparent that these indentations or depressions 4, in one face 3, are diametrcally opposite in transverse planes the indentations or depressions 4, in
the lother face 3, of the bar or member.A
7, into which 'merge the end and side walls,
as shown in the transverse section, Fig. 3.
Inthe faces'S, 8, of the bar 2, are depressions or indentations 9, which are formed by inwardly curved oppositely 'disposed `end Walls 10, beveled opposite side walls 11, and a fiat bottom 12, into ,which merge the said side and end walls. Said depressions are adapted to form intermediate spaces as 13,
which corres ond in shape to the formation or contour o the indentations or depressions 4, in the adjacent faces 3, 3, respectively, of the b'ar. Likewise do' the said depressions ll, produce s aces as 14, to correspond in shape to the 'ormation or contourof the indentations or depressions 9; in the faces 8 8, res ectively, of the bar.
articular attention is directed to the fact that in view of the position` of all of the depressions or indentations they assume a, staggered relation when traced in' a spiral trend circumferentially of the bar, and this fact also applies to the relation of the intermediate spaces formed by said indentations or depressions.
The spaces 13, intermediate the'indentafrelativef position .of the inwardly curved I 1.0 ,Walls/110,' of the-indentations or depressionsl .9, and ,thereby effect a uniform vareain cross sections, as shownin Figs.. 3, 4, and 5. t

obvious that any two faces may be provided f unto appended, Without departing from the spirit ofthe invention.
Having described the invention, what is claimed is: Y

' In testimony whereof I. have hereunto set my hand 'in presence of two subscribinglwitnesses.
