To all whom it may concern Be it lmown that we, 'CHABLES 13. Soon, residing in the city of Philadelphia, Pennsyl'vania, and HARRY Fos'rnn, residing in the city of Medford,-"Oregon, both being citizens of the United States, have invented new and. useful Improvements in Metal Posts and Poles; and we'do declare the following to be a full, clear, and exact de scription of the invention, such as will" en-' able others skilled in the art to which it ap pertains to make and use the" same, reference being had to the accompanying 1 drawings. Our invention relates to metal posts and poles adaptedtobe formed in sections or segments, preferably of sheet metaland adaptedfor use 'as telegraph) poles, tele phone'poless etc, and which will be strong and durable 'as well ashighly eificient and effective in iise.'-
An object of the invention is to. provide posts and poles of this character which may e employed as fence posts and gate posts andfoiivarious other fplurposes and which are constructed, to wit strains to which such posts are'subject.
poles of this-type whichwillfbeformed off the minimum number of parts of'simple con- ,struction and which will be strong and du A further object is to provide posts and to manufacture.
' fWiththeabove and other objects in View,
our invention consists in certain novel constructions, combinations, and arrangements of arts to be hereinafter more fully de scri ed, claimed,'and illustrated in-the'jaccompanying drawings, in which, v
Figure l is a detail-perspective view of one of the segments employed in the construction of our improved posts and poles;
Fig. 2 is an elevational view of the complete device employed asa telegraph pole constructed ofthe preferred. form of segments; Fig. 3 is a plan 'viewof the form of post-shown in Fig; 2' with: the cap removed;
Fi-g. 4 is across-sectional' view through this form of post; Fig. 5 is' a-fraginentary de- .ta-il sectional view on the line 5-5 of'I ig.
4', Fig.6 is a view similar to Fig. 4, showing a di erentfform of reinforcing means for the post; Fig. 7 is a fragmentary detail View with I parts broken away to more clearly illustrate the form of reinforcing means 'eta et eiFiie. 1 5 i s. 8 as ea -W stand" thrusts and is a view similar to Fig. 1' showings. modified form of segments"; Fig, 16 is a crosssectional aview through the ,post constructed of the modified form-of segments.
Referring more "specifically to the drawdes'ignate corresponding parts throughout theseveral views, 1 designatesthe segments ,oii'rimprovecl posts or poles and by referring to Fig. 1, it will be noted that the-segments orsections are infthe form of re tangularpl'ates ofmetal or-the like curved transversely, and by referring to Figs. 3
and l, it will be seen that these segments" orplates are placed with'their concave faces positioned outwardly to form the outer face "of substantially 1 triangular post, three of the segments or'plates being employed for each eng'th or section'f'of the post or pole. It will be, understood, however, that theplates may be of such length as to extend from one en'd 'to the other, of the post oi-pole instead of formingth'e post or pole in sections. The longitudinal edges, of the segments orplates are secured together by the rivets 2 01 other 'suitable means, as clearly, shown in Figs. '3' and 4." When the post, is'formed in sections, the lower hori- ,-ing eachsection above the lowermost section are secured to the "uppermost edges of the thereben'eath, by'mean'sof the rivets 3,"or the like, 'itbeing; understood that the seg 'inents or plates 1 preferably taper toward their upper ends, thereby making it possible (in-pole in upright position. The upper end.
of the ,up'permostsection is' closed bythe cap 5 which is snugly engaged over the upper, ends-,of the segmentsor plates form ne' s jerr m was i or sectionsemployed to'jform the body of zontal edges of the segments-orplates for-m segments or plates forming the section ployed upon the reinforcing rods; Fig; 15
'ingsidwhich' similar reference characters for the lower edges of said segments or An ordinary cross arm 10 of an ordinary telegraph post or pole is secured against oneside of our improved post or pole by the T-bolts 11 engaged therethrough and through opposite corners or longitudinal edges of the post or pole and having the nuts 12 threaded thereon while the heads of said T -bolts are engaged against opposite sides of our improved post or pole, thereby prm outing rotation of the bolts 11.
When the post or pole is to be subjected to great strain and the strengthof the post or pole must therefore beincreased, the segments or plates 1 may be increased in thickness and the post or pole may be reinforced by the reinforcing core member 13 placed inside of each section of the post and having three concave faces conforming to the inner faces of the segments or plates 1 and also having three straight portions between the curved faces thereof. The three concave faces of the reinforcing core member 13 are vertical and said member 13 has three inwardly directed horizontal walls 14 extended inwardly from the lower edges of the verticalconcave faces thereof, thereby greatly increasing the strength of the reinforcing core imember. The member 13 is held "in position and drawn against the three inner walls of the post or pole by the rods 15 which extend inwardly through the concave walls of the 0st or pole and the correspondin Walls of the reinforcing core member and have their inner threaded ends engaged through the opposite straight portions ofthe reinforcing core member.
In Figs. 6 to 14, inclusive, we have shown another form of reinforcing means which consists of reinforcing I-bolts 16 which have their threaded ends projected through elongated vertical openings 17 in the concave walls of the post or pole and have the nuts 18 engaged thereon. Beneath the nuts18 are washers 19 which have spaced lugs 20 upon their inner faces and adapted for engagement through the, elongated openings 17. Threaded upon the reinforcing I-bolts 16 within the post or ole are the stop nuts 21 insertible through the elongated openings 1.7 which have concave outer faces conforming to the curvature of the inner faces of the segmental plates and adapted to be engaged by the same, thereby limiting inward movement of thesides of the post or pole and formin a rigid and reinforced.structure. It will fie seen that the reinforcing I-bolts 16 are crossed and the opposite or inner ends thereof are secifirely retained in position by the anchor bolts 22 engaged transversely through the corners or longitudinal edges of the post or pole and through the eyes 23 of the I-bolts 16, said anchor bolts 22 being secured in position by the nuts 24: or other suitable means. the anchor bolts 22 are engaged through the preferred construction It will be evident that as eyes of the reinforcing I-bolts l6, rotation of the latter will be prevented and asthe legs 20 on-the washers 19-are engaged through 'the vertical elongated slots 17 above and below'the stop nuts 21, rotation of said washers 19 and stop nuts 21 will also be prevented after the nuts 18 have been threaded upon the bolts 16 to proper position against the outer faces of the washers 19.
In the modified form of post or pole shown in Figs. 15 and 16, we have shown the segment or plate 1 as having one longitudinal edge 29 turned back toward the convex or inner face of said segment or plate. In assembling this form of segment or plate to produce the post or pole or a section thereof, the segments or plates'are placed in the same position as in the preferred form with the concave faces turned outwardly and the smooth or straight longitudinal edge of each segment or plate is engaged in the turned back edge 29 of the adjacent segment or plate and the rivets 30 or othersuitable se' curing members are engaged through said straight and turned back edges. The 30st or pole is reinforced by the corner rein orcing members 31 which are of substantially triangular form in cross-section and which have their narrow edges on aged between the interlocked straight an turned back edges of the segments or plates 1, whereby the rivets or other securing means 30 will also be engaged through the thin edges of the reinforcing members 31 to retain the same in proper position.- A telephone or telegraph cross arm 32 of any ordinary or may be secured against one side of the post or pole by the substantially V-shaped securing bracket member 33 which has its bight portion 34 engaged around one longitudinal edge of the post or pole while the outer extremities of its legs are extended parallel, as shown at 35, and engaged transversely through oppositesides of the post or pole and through the straight side thereof, said extremities also extending through the cross arm 32 having the nuts 36 or the like threaded thereon to retain the cross arm in position.
It will be understood that the main portion of the legs of the bracket member 33 are curved inwardly and against the opposite sides of the post or pole.
From the foregoing, it will. be apparent that we have provided an improved and simplified form of metallic post or pole and which may be readily employed for various purposes and which will be highly efficient as well as strong and durable in use. It will also beevident that the post or pole may be made any desired length by employing the proper number of sections. It will therefore be understood that while we have shown the preferred embodiment of. our m-- of construction and arrangements of parts may be made Within the scope of the appended claims without departing from the s irit of our invention or sacrificing any 0 the advantages of the same.
\Vhat We claim is 1. A device of the character described comprising a post formed of a lurality of plates, the longitudinal edges 0 the plates being engaged one with the other, each of said plates being provided at predetermined points with elon ated openings, anchor-bolts disposed throng 1 the post adjacent the corners thereof, reinforcing bolts engaged with said anchor bolts and projecting through the elongated openings, said projected portions of the reinforcing bolts being threaded, a stop nut threaded upon each. of the reinforcing bolts and in contact with the inner face of a plate, and clamping means engaging the projected extremity of each of the rein forcing bolts,- said means including a washer provided with projections adapted to be accommodated within an elongated opening.
