Application i for reissue iled June 17, 1930. Serial No. 461,829.
This invention'relates to tubular steel poles such'as used for electric power'transmission lines, telephone and telegraph poles, etc., and
' especially to' a modified form of the'steel pole 5 shown in my co-pending application entitled Steel polef filed April 2, 1927, Serial No; 180,416. g
The object of the present invention is to generally improve and simplify the construction and operation of poles of the character described; to provide a tubular pole enclosing a plurality` of casings for the purpose of transferring electrical Vwires or cables from overhead tounderground construction or vice versa; to provide a tubular pole enclosing a plurality o'f casings spot Welded or otherwise secured to the inner surface ofthe pole and to each other to reinforce and promote rigidity in the polel structur'cg'to provide a sectional tubular pole within enclosed casings in which the casings and tube sections form integral units; to provide a connection for each pole section which is'telescopic in structure and which Valso permits simultaneous teiescoping of the casings when two pole sections are tele-- scoped and assembled; and further, to provide a tubular pole enclosing casings which are bent outwardlythrough openings in the pole section, either at the upper or lower end thereof to permit the entering or taking out of electrical wires or cables, the upper end outlets being arranged to direct the wires or cable to various cross arm positions andthe lower ends to direct the cables into underground conduits, etc.V l Theinvention is' shown way of illustration'in the accompanying drawingsin which l is a side elevation of a" pole, lsaid side elevation being partly broken away,
Fig. 2 is lan enlarged vertical central section ofv that portion of the pole where the casings are bent outwardlyjtoform outlets for the `wires or cables extending through theI pole,
Figs. 3 and 4 are enlarged vertical longitudinal sections of theadjacent ends oftwo pole sections, said views showing the telescop-V Fig. 5 is a cross section taken on the'line Fig. 6 is a plan l view of the upper end of the 'it yis uniform inv diameter throughoutits length. The remaining sections'indicated at 2 andv 3 are alsoftubula'r but they taper from end to kend so as'to 'provide-a, series of telescoping sections.; vlila-'ch tapering section is constructed of Asteel or like materialA and thev metal employed in: each section is preferably decreased in thickness from'the bottom" to the top, i. e., the metal employed in thebase section is the heaviest, the metal in the section indicated at l2v is slightly lighter,y etc.V The particular. method of constructing each-individual tubular section is of nofmaterial importance. Suiiice it` to say that each section may be made up of two half-sectionsqwhich may*v bev stamped or ,rolledl andV which are lapped. buttwelded or otherwise joined.
` The description so fa'rzsubmitted describes a pole substantially identi- Calto that illustrated in my c'o-pending application already referred to., The novel featuresto` be considered in connection with the present application areas follows Y n I` First--A tubular pole ysuch as described enclosing a plurality of pipes or'v casings which are integral `'therewith byv welding or otherwise `securing thecasi'ngs or pipes. interiorof the'tubular poile. g Secondly-A tubular pole of this character in which one end of the interior casings is bent outwardly through openings in the pole to form outlets or inlets for wires, cables, etc.l

A pole of this characterhas been found to be exceedingly `rigid and substantially "ebnstructefd; These 4poles are readily manufactured and they are easily assembled and erectedin the field. The conduits due to the telescoping connections provided are unobstructed throughout their length, thus makingit comparatively easy ltoenter and place the'ables in position.'l Each poleV section` may be galvanized, both eXteriorly and` interiorly or it may be treatedwith asphalt coatings or the like, thus materially increasing the life of the pole.r The thickness of sheet metalvemployed rin the pole sections `Zand 8 mayin this instance be redu'cedto a consid` erable extent in view voff the internal. rein.- forcernent obtained by the ycasing sections 6., i.'y e., the metalin the `pole sections may be lreduced in gauge orthickness when compared with the structure in my (3o-pending application. u f
