COLLAPSITBLE METAL IEOLE.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed April 4, 1914. Serial No. 829,516.

To all whom it may concern Be it known that 1, Oscar: VALENNE, a subject of the King of Belgium, and a res1- dent of New York, county and State of New York, have invented a certain new and useful Improvement in Collapsible Metal Poles, of which the frllowing is a full, clear, and exact specification. V

This invention relates to a class of poles adapted to be used for suspending wires, electric lamps, and the like therefrom.

My invention has for its object primarily to provide a collapsible pole designed to be employed for supporting telegraph CI trolley wires, electric lamps, and the like by making the pole of metal in a form whereby it will effectually withstand the force of high winds and stormy weather, and which is made in separate parts in a manner whereby a large number of the poles may be manufactured in entirety and subsequently assembled without the use of connecting bolts,

thereby dispensing with the requirement for skilled workmanship in the erection of the poles. This is ilCCflllPllSllQtl mainly by providing three substantially \l-shaped members,(tr standards which are disposed in spaced relation in the formation of a triangle so as to converge upwardly toward each other, and these standards are connected by a number of detachable spaced metal retaining elements, or-straps which serve to prevent the standards from accidental displacement when the pole is assembled as well as permitting the parts of the pole to be readily discrnnected when it is desired to remove the pole, or when one or more parts thereof are to be replaced by others in event of being damaged. 1

A further object of the invention is to provide a collapsible pole of simple and oilicient construction, and which is susceptible of being made in various sizes so as to combine great strength and durability.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings which forma part of this specification, and will then be pointed out 1n the claim as the end of the description.

In the drawings, Figure 1 is an elevation, partly broken away, of one form of metal pole embodying my invention when used for supporting wires. Fig. 2 is an ele vation of a form of the pole when used for supporting trolley wires, electric lamps, or

the like. Fig. 3 is an enlarged top plan, partly in section, of one of the triangular metal straps used in coniunction with the pole. Fig. 4 is an enlarged perspective view, partly in section, of one of the corners of the strap shown in Fig. 3. Fig. 5 is an enlarged perspective view showing the underside of the cap employed in the pole. Fig. 6 is an enlarged top plan of the cap. Fig. 7 is an enlarged fragmentary view, partly in section, showing ('ne of the standards of the pole embedded in the ground when erected, and Fig. 8 is an enlarged view taken on the line II-II of Fig. 2.

The collapsible metal pole has three members, or standards 10, 11, 12 which are alike in formation, and all of the standards are preferably substantially V-shaped, as viewed in cross section. lhe standards 10, 11, 12 are made of steel, or other suitable metal, .and these standards may be of any desired length, width, or thickness, as cccasion requires. When the pole is erected the standards 10, 11, 12 are disposed in spaced relation in the form of a triangle so that the upper parts thereof will converge toward each other, as illustrated, and the lower end of each of the standards is bifurcated to provide two diverging prongs, as 13 and 14.

To erect the pole the lower end portions of the standards 10, ll, 12 are embedded into a block of cement, as 15, after being properly disposed in triangular arrangement, and the block of cement as well as contiguous parts of the standards are then sunken in the ground, as 16, to a suitable depth. Previously to erecting the pole in this manner, and after the standards 10, 11, 12 are triangularly arranged with relation to each other, the standards are detachably connected by a number of retaining elements, or straps, as 17, all of which are similarly formed, excepting that all of the straps vary somewhat in size. The straps 17 are madeof steel or other desired metal, and each strap is triangular in sha 2e to conform to the formation of the standard when arranged, as explained. Each of the straps 17 has three enlarged corresponding corner portions l8, 19, 20 all of which are substantially the shapes of darts, as viewed transversely, and each corner portion has an approximately fiat longitudinally disposed body, as 21. On the outer converging edges of the body 21 of the enlarged corner of each strap is a vertically disposed substantially mitting the straps to be removed therefrom when it is desired to disassemble the polefor the purpose of removing it, or'for replacing parts thereof in event of being damaged. The dart-shaped corner portions 18,

w 19, of each of the straps are connected by cross-bars 21-, 25, 26 which are preferably T-shaped, as viewed in cross-section, and

, these bars are integrally formed with the corner portions so that the pole may be made in a comparatively limited number of interchangeable parts to permitthe pole to be transported in sections and readily assemled when being erected. To connect the standards 10, l1, 12 by means of'the retaining elements, or straps '17 after the standcards are triangularly arranged, as above referred to, the largest strap is guided over the standards so ascto be' disposed on the lower parts thereof. The other straps are then similarly applied on the standards in spaced relation in the order of their sizes so that the smallest strap will be at the top part of the standards, and on the top of the standards is a removable metal cap, as '27. -The cap 2? is substantially triangular in shape, and in the underside ofthe cap adjacent to its corners are approximately V-. shaped recesses 28, 29, 30. The recesses 28, 29, 30' are slightly larger than the standards to allow the upper end of each standard to be disposed in one of the recesses, and, through the centerof the cap is an opening 31 to permit a bracket, as 32 Fig. 1, to be applied to the pole Whenthe pole is usedfor supporting electric wires for telegraphing'or other purposes on the upper-part of, the pole are fastened one or a number of brackets, as 33, on which may be mounted a suitable numberof cross- 'bars,-as 3-l Fig. 1, and these cross-bars as o well as the bracket 32 serve to permit the Copies of this patent may be obtained for five. cents each, by addressing Washington. D. C.' I

electric wires to be connected to thepole by the'usual, or any preferred means. 'When the pole. isemployed for supporting trolley wires, as 35, or electric lamps, as 36, and the like, a form of bracket, as indicated at 37,

may be mounted on the upper part of the pole. By constructing the collapsible pole with the forms. of the spaced 'V-shaped standards, together with the forms of the straps, as herein described, it is obvious that these parts may be made in comparatively limited sizes, if desired, but will tend to combine sufiicient strength and durability for. being capable of withstanding high winds and stormyweather, and by making the pole in the separate interfitting parts it may be readily assembled and erected with.

out-the use of bolts, or other connecting means. i

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understoodas limit- 7 ing myself thereto, as I am aware that modifications maybe made therein without de-- parting from the, principle, orsacrificing any of the advantages of this invention,

therefore I res'erveto-myself the right to make such changes as fairly fall within the" scope of the appended clain Having thus described my invention, I

claim as new and desire to secure'by Letters Patent A collapsible pole comprising three pole sectionsof acute angle formationfin'cross section, the lower ends thereof being adapted to be anchored in the ground, pole-section binders disposed at intervals along the length of the pole, each binder comprising 7 three dart-shaped corner portions and each na'lly'disposedcbody and a vertical flange at the outer converging edges thereof, said' flange having vertical passages therethrough corner portion comprising a fiat longitudi frictionally receivingthe polesections and integrally formed T-shaped cross-bars connectmg the corner-portions, and a cap for the upper ends of the sections.

This specification'signed and witnessed this third day of April A. D. 1914.
