To all whom, i# may concern:
Be it known that I, Wimmer Mensen, e citizen of the United States residi et New Yorlrn the oonnty of New 'i'ork an New York, have invented certain new and useful Improvements in Concrete-Steel Construction, of which the following is e specification.
My invention relates to conoretefsteel construction, and its novelty consists in the construction and adaptation of the arts, es will be more full hereinafter pointe out.
In an app `cation for Letters .Patent of the me October 13, 1904, Serial No. 228,342, here Yshown end described n form of ber adapted tube embedded in concrete and to form a. unitary structure with its concrete envelop, which bar cornprises a lon itudinbl body provided with external spiral arranged ribs, whereby e resistanoe isa. orded to the movement of the and yet at the same time the cross-sectional area of the b'er in a plane at right angles to its longitudinel exis is substantially constant and of uniforni' character, end therefore the tensile strength of the bar,end, what is more important, its elongation under stress is substantielly uniform et all points' along its length.
ln another e. lioation filed by me April 20, i905, Serie o. 256,5?9, of. which the present application is e division I have shown sundry modifications of the bar of the application before referred to'. The subject-metter of this present application elsooomprises sun dry modifications of this form nl bar, and hes for its object the produntion o n. oer wiiieli while varying somewhat in form and proper tions from those described in the applications z referred to yetr possesses the advantages of Vsuch bars, while sit the same time it has otheradvantages peculiar to'itself and may per- SSV hops be more readily manufactured.
In the drawings, Fivure l is u. longitudinal elevation Yof s. bnr embodying my invention, showing the concrete envelop in section in two planes, thegutline of the bnr being shown dotted wlfere it is concealed. Figs. L2, 3, and 4 are transverse sections at right angles to the longitudinal exis of the bei* on the planes oi the lines 2 2, 3 3, and 4 4 in Fig. 1. Fig. 5 is s. longitudinal elevation of the seine har, showing the :modification or distortion w ch occurs in its shape when the two rolls through whichitisformed do not. exeotlyre isterwlule this operation is taking pisos en Figs. G, 7,
State of vintegro with et boeg of th if.
end S are transverse sections at right angles to the longitudinal axis of the bar on the planes of the lines 6 6, 7 7, end 8 8 in Fig. 5.
The drawings represent e bar of metal, preferably iron or steel, which has been rolled or otherwise fashioned into the forms shown'. It comprises e lo itudinal body 21, of syrinmotricel form en .provided with external ribs 22, 23, and 24, variously disposed around and projecting from the body-21. The body 21 is shown in the illustrations esalo cylinder; but i may well have any polyjgon shape in crosston, so long as its trnnsyerse sectional area is uniform at ell points. The extornai ribs 22, 23, endr24 are. referehly mede Their sise contrgsted with the odyotheber may be varied to suit dilerent circumstances-,of use,V
but about the pro ortions shown in the drewings are usual an convenient.. A In encres-secF v.
tion each one of these ribssbove the 'boil of the bar resembles somewhet, the shape o an ordinal" tooth of toothed gearing'. The ribs are eao arranged symmetries. with reference to the longitudinal axis of tile bar.. Y
Referring specifically to :Fis
heey of te@ im is provided wir. Perser halfspiral ribs 22723, arranged to encircle the bar hel-wsgsronnd and terminate in the longitudinel ri at such points es theywouldin'te- Y seet if prolonged. Goincident Vwith one-half of these points of junction aretino longitudinel ribs 24 24, substantially parallel with the vlrnigitnclinel exis of the 'naar'.Y t'will be seen that by this arrangement speees roughly diamond-shaped are left between the ribs. These spaces are ada ted to reeeive the oonerete and assist in ho dingthe ber enduits envelop together after they are once in place. it willof course he understood that the numher of hulifspiral ribs may be yaried on a given size of ber.
The her Ymede es described has suhstnn tielly the saine cross-sectional area in ell lanes et right angles to itslon itudinel axis. ETheoretically, et the e @les nrned by the junction of the longitudine ribs with the spiral ribs this oross-seotionel aree would be slightly less for such decrease in aree the ongle of junction isrounded out slightly and a littlernore Vmotel is left et that point, sores toinelre the sectional eren of theV her et that point uniform' with that et the other oints Along its length. Another metter to IOO IGS
e noted is that ell oblique seetions of the ber ere greater in is seen that the ribs 22 and 24 are close together on one side and the ribs 23 and .24 likewise close together on the opposite side ofthe bar. ln Fig. .'i the ribs 22 and 23 are somewhat separated. and 2-1- are at the farthest iossible. distances apart ,.being separated by substantiallv ninety degrees. In all of these sections, the eombined area of the ribs is substantially identical.
In Figs. 5, 6,7,and 54 there is shown a modified form of the bar illustrated in the preceding figures. It happens in rollin@r the bar that sometimes the two rolls eniprloyed are not registered with sullicient care and the upper half of the bar is not in precisos-ymmetrieal relation with the lower halt' ol' the bar. [n Fig. 5 this is shown inslightly exaggerated form in order to make. the situation clear. This non-registration of the rolls is apt to oet-ur, and it` has occurred frequently in every rolling-mill, and is a difficulty which iron-masters have long sought to overcon1e,'
but have not overcome except'at an expense entirely disproportionate to the result sought to be obtained. When a bar of my improved form, however, is employed, it makes no difference whether the rolls register or not, be-
cause the cross-sectional area of the bar at allv @and S, showing eross-seetions of the bar illustrated in Fig. 5. By these sections it will be seen that while. the ribs 22, 23, and 24 are not at any place synnm-trieally arranged around the periphery otl the intersecting eil'- cular plane, vet nevertheless their combined area is outside of the body ol'the bar, and eonswpxentiv the cross-sectional area atl all ot' these points is at all times the saine.
llaving in View the principles governing theeonstruetion ot' this form of concrete barnamely, that the body of the bar shall be of' a regnlarlv-formed ventral body and pro-,
`vided with external projecting ribs ol' unilorm eross-seetlon, one oln said ribs being -ob- In Fig. 4 the . ribs 22, 23, t
practicing the principles stantially parallel to the loneitudinal axis ot the body, and extending a substantial part of the length ot' the body, and another rib beginning in said longitudinal rib and extending diagonally therefrom at least half-way around the body, the whole structure being of uniform cross-sectional area throughout the lengthof the ribs.
2, A bar adapted to be used as a eore to be embedded in a concret-e envelop comprising a regularly-formed central body, and provided with external projecting ribs of uniform cross-section, one of said ribs` being substantially parallel to the lon iitudinal axis of the body, and extending a su xstantial art of the length nl' the bod and a plura ity of others beginning in sait longitudinal rib, and extending diagonally therefrom at least halfway around the body, thewhole structure being of uniform cross-sectional area throughout the length of the ribs.

A bar adapted to be used as a core to be embedde in a concrete envelop, comprising a re ula '-formed central body, and provide( with externat projecting ribsof uniforni cross-section, a p urality of said ribs being substantially parallel to the lon itudinal axis of the body, and extending a su stantial part of the length of the body, 'and another rib diagonal thereto-and beginning in one and terminatingvin another of said longitudinal ribs, the 'whole structure being of uniform crossetonalarea throughout ,thel length of the'lfibs.14 t" i l i y 4.
