roLE.

Be it known that We,WiLL1`AM-Ronnnrs and CARROLL Ronnntracitizens of the United States, and both'residentsofspringlield, in the county of Clark and State ofOhio', have invented a neviT and Improved Pole, of which the following is a clear, andexact de-` 'F scri 4tion.r

' 'sinventionrelatestfpoles, and is particularly useful in connection with concrete More specifically, the invention relates to poles or `standards formed .from concrete or other plastic substances, adapted subsequently to hardemand having as reinforcing artially embedded therein, 'If-ironsv or siin arelonfat'ed members, and further having annular `holding membersencompassing the tension members, the poles 'being formed in' sections seform.

cured .togetherby aeonnection-- o'f special objeetof invention to. provide a simple7 stron@ and inexpensive' concrete' ole 1 for carrying e ectric wires'andthe like, w 'ch can beasily manufactured, and isattractive in appearance, and which` has abase -or butt so formed that the metal' or other 'tension members`- are embedded therein and thus-do Withthe ground.

A` further object of Vthe invention' is to provide a pole of the class described which may consist `of a number of `sections,fan ';l which has suitable means for firmly lsecuringV the sections together.

A still further object, of the invention is to previde a pole ,the body of whichfis fashioned A rom concrete or the like, andwhich has tension membersl of metal or other suitableniaterial and of standard-types 'or forms. l

` Thelinvention consists kin'the construction and combination'of parts-to be more fully described hereinafter and particularly set forth in the claims.y y.Reference is tobe had to the accompanying drawings forming a part A,of this specification, in which similar characters of reference and in which indicate corresponding parts in' all the' views,

Before planation .of ouryinvention, it should bey clearly understood that While the term coni crete -is used hereinafter in the description and in the claims, We ldo not wish to limit ourselves to this-com osition, but `use it merely as an exam le.,

he body of the pole can from any suitable plastic materialor co`n1 osition whichis adapted subse- .quently to arden or set. `The reinforcing members consist-preferably, of standard iron or steel pieces such asT-irons, rings or the like. Certain of the parts, such as7 the connecting members between the pole1 sections, are-necessarily o'f special form and may be proceeding to a more detailed ex# specisaatidn of Lettersrateat. ratentedepie?, isos.

fashioned from cast-iron or any otherl Inaterial adapted tothe purpose. We prefer to form the piece,` andffor heights exceeding a-certain eight, we prefer to form them from a lurality of sections, preferably two in num er. The pole has `an enlarged base -or butt which is embedded in thegrund or otherwise suit! ably supported,it0 hold the pole in a perpendicular or normal osition. The tension and reinforcing mem ers are full 'embedded inthe butt, so that vwhen the pov e isin positio/n in theground these -membersare not subject to corrosion and do not come in contact with the ground. e.

' Referring'more particularly to the drawings, 10 represents the concrete body ofthe o e, which tapers outwardly to an enlarged utt 11. The pole is preferably tapering in has a lon 'tudinal bore 12 which renders the pole. ho ow and cpnsequently, lighter.' VVeemploy tension members, comprising T-irons 13-having webs 14 corrugated or otherwise roughened, and ilanges 15 of the usual form. `The tension members 13 .are arranged 'longitudinally of the pole body and 'Y 14 embedded therein. The flanves 15 lie adjacent to the outer 'surface of ybody, as is, Shown [most clearly in Figs. 3 and4. .Annular bands 16 are arranged upon the pole body at separated points and encompass the body together with the tension poles for certain heights, of one` ,-encom assing members 16 may be lmembers 13. It will be understood that the I,tension members 13 are embedded in the concrete when the pole bodyis molded. The laced upon t ie pole body at the same time, t ough we prefer to shrink them in position after the pole body has been molded. The tension members 13 extend into the butt 11 of the ole and are completely embedded therein. hey are embraced by rings 17 which are of course, likewise embedded, and u-*hichserve to strengthen the butt as well as to hold the members 13 in position when the pole is bein molded.

hen the poles are intended to be comparatively' low, the upper end is provided with a suitable ca to close the bore 12, or the concrete` itsel` is formed into a closing cap. lVilhen a further section is desired upon the body 10, a crown 18 is used which fits upon the top of thexpole and is adapted to carry a removable annular collar 1.9 having a later- .ally extending flange 19a. The crown has recesses 20 which receive the upper ends of the tension members 13. The crown further, has openings which are adapted to re- 'ceive the projecting ends of bolts 21 having the Shanks preferably of sinuous form and embedded in the pole body 10. The bolts have nuts 22 which serve to hold the crown securely in position.

The section 23 fits into the collar 19 and is formed Afrom concrete, has a bore 24 which renders it hollow. At the upper end, the concrete is formed into a cap The section has reinforcing tension T-irons 26 similar to the irons 1.3, and held in )osition likewise,v by annular members 27. Ti' ends of the members 26 are outwardly dis osed and engage at the under side of the col ar 1Q and the flange 19a, thereby serving to hold the section firmly in position. at the. cro'wn. The collar and the fiange have suitablr` poel;- .ets 28 underneath the flange, which are formed to receive the laterally disposed ends of the tension members 26. The pole body or the section 23 may be provided with cross arms 29 or other suitable means for carrying the electric conductors and the like. Having thus described our invention, we

claim as new, and desire to secure by Letters Patent:

1. A pole, comprising a concrete body, T-irons arranged longitudinally of said body and provided` with. corrugated webs, said T-irons having the webs en'ibedded in said body, rings encompassingl said T-irons at separated points, said pole having an en larged butt, said T-irons being completely embedded in said butt, rings embracing said '1'-irons within said butt, a section mounted upon said' body, andmeans for securing said body and said section together.'

ie lower 2. A pole, comprising a body, a removable section, a crown upon said body having means for holding said section,'said section having tension members with laterally disposed ends cngaging at said crown, and means for securing said crown in position.

3. A pole, comprising a concrete body, a concrete section, said body and said section having tension members partly embedded therein, a crown carried by said body and engaged by said tension members of said body, said crown being formed into a socket to receive said section, said tension members of said section being disposed to engage at said crown to hold said section in position, and means carried by said body for removably securing said crown in position.

4. A pole, comprising a concrete body having a crown at the upper end thereof, a concrete section having a collar secured at the lower end thereof, and means for securing said collar to said crown, said body and said section having longitudinal tension members partly embedded therein and engaging re spectively said crown and said collar.

5. A polo, comprising a concrete body having a crown at the upper end thereof, said body having tension members partly embedded' therein, sa'id crown having recesses adapted to receive the. upper ends of said tension members, a concrete section having a collar at one end thereof, and means for mountinglsaid collar securely upon said crown, said section having tension members iartly embedded therein and provided with laterally disposed extremities, said collar having pockets adapted to receive said laterally disposed extremities of said tension members of said section.

6. A pole, 'comprising a concrete bodyT and a concrete section having longitudinal tension members partly embedded,therein and annular membelrs at the outside encompassing said ,tension members, an annular crown mounted upon said body and having recessos adapted to receive the upper ends of said tension members of said lody, said tension members of said section having the lower ends outwardly disposed, an annular collar upon said section and having pockets to receive said outwardly disposed ends of said tension members of said section, and bolts having sinuous shanks embedded in said body and engaging said crown and said collar to secure the same together.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
