TELEGRAPH-POLE.

SPECIFICATION forming part Of Letters Patent NO. 406,406, dated July 2, 1889.

Application filed October 8, 1888. Serial No. 287,544. (No model.)

To aZZ whom it may concern; quirements. These standards are secured to- Be it known that 1, CHARLES M. RUSSELL, gether by a series of brackets or spiders D, a citizen of the United States, residing at which will preferably be made of cast-iron, Bowling Green, in the county of lVarren and the standards being extended through vertical State of Kentucky, have invented certain new holes in the arms of said brackets, said brack- 5 5 and useful Improvements in Telegraph-Poles; ets being of different sizes, with the standardand I do hereby declare the following to be a holes diiferent distances apart to correspond full, clear, and exact description of the invento the area of the tripod at the place where tion, such as will enable others skilled in the the brackets are to be secured. The upper IO art to which it appertains to make and use bracket will be held in place upon the rods, the same. preferably by nuts a, as shown in Fig. 1,

This invention relates to improvements in while the lower one will rest upon (prefertelegraph-poles and insulators therefor, the ably) a foundation-stone b, the standards beobject of the invention being to provide a ing extended entirely through said stone and I 5 skeleton telegraph-pole which shall be strong, held by nuts. The intermediate brackets durable, and ornamental, and which shall be will be slipped on the standards from the top light, portable, impervious to moisture, and before the top standard is secured thereto practically fire-proof; also to combine with and forced downward until they bind, where said telegraph-poles insulators of such conthey may be keyed, if desired. It is prefer- 2o struction that they may be placed upon the able to use piping for the standards, as rigidwires so as to incase them and be secured to ity is secured with lightness of construction. the cross-pieces of the pole without the use of It is obvious, however, that angle bars or rods the usual dowel-pins, as hereinafter fully set might be used instead of the pipes without forth. departing from my invention.

25 \Vith these objects in view my invention The cross-pieces E, which may be conconsists in the special construction, combinastructed of wood or'metal in'the usual form, tion, and arrangement of the several parts of are secured to the upper ends of two of the the telegraph-pole, substantially as herein standards A B by eyebolts or staples c, which after described, and set forth in the claim. encircle the standards and extend through 30 Figure 1 represents in front elevation a me the cross-pieces, where they are secured by tallic telegraph-pole constructed in accordnuts 0, the incline of the standards and posiance with my invention; Fig. 2, a sectional detion of the eyebolts preventing the crosstail of the post on dotted line .9300, Fig. 1, showpieces from slipping down. Each of the ing one of the triangular spiders or brackets cross-pieces E has a series of transverse hori- 3 5 through which the standards of the pole eX- zontal holes d cut through it, with a trans- 8 5 tend; and Fig. 3, an enlarged detail showing verse notch (P, out from the upper edge and the manner in which the cross-piece is secommunicating with the hole (1'. cured to the standards of the telegraph-pole, The glass insulators F, which encircle the the cross-piece being shown in section; and wires F, are inserted into the holes (1 in the 40 Fig. 4 represents in elevation a modified concross-pieces, said insulators being constructed o struction of base to be driven into the ground in two halves.

If desired, the lower bracket may be firmly secured to the lower ends of the standards by nuts or otherwise, with the ends of the bolts extending a considerable distance below, so as to be buried in the ground, in which case the foundation-stone will. be dispensed with, or the standards may have a pointed base, each to be driven into the ground, said base having longitudinal tapering radial ribs, as shown in Fig. i.

I claim In a telegraph-pole, the combination of the tubular standards A B 0, arranged in the shape of a tripod, the cast-1netal brackets or spiders having the vertical holes, through which the standards are extended, the crosspieces E, having transverse horizontal holes therein to receive the insulators, the staples 0, extending through the cross-pieces and around the standards, where they are secured by bolts, and the insulators seated in the holes in the cross-pieces, so as to not proj eet above orbelow said cross-pieces, whereby the cross-pieces may be secured to the standard in close proximity to each other, substantially as described.
