ORVILLE MARSHALL KNOX, OF KNOXBORO. NEW YORK.

POLE.

Specification 02 Letters Patent.

Application filed August 8, 1917. Serial No. 185,127.

To all whom it may concern:

Be it known that I OnvILLr. M. Knox, a citizen of the United States, residing at Knoxboro, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Poles, of which the following is a specification, reference being bad to the accompanying draw- .ings.

This invention relates to certain improvements in poles and has relation more particularly to a device of this general character especially designed and adapted for use in connection with telegraph or telephone lines and it is an object of the invention to provide a. novel and improved device of this general character formed of metal, preferably rolled steel and which has reinforcing sections co-acting with the opposite faces thereof in order that the pole may possess a maximum of strength.

It is also an object of the invention to pro vide a novel and improved device of this general character wherein the lower portion thereof has its opposite faces provided with casings of cast iron in order to protect the lower portion of the pole when embedded within the ground from corrodiug.

The invention consists in the details of construction and in the arrangement of the several parts of my improved pole wherein certain ii'nporta-nt advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and ad vantagcous for use, as will be hereinafter more fully set forth.

The novel features of my invention will I hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to dcscribe the same with reference to the accompanying drawings wherein Figure 1 is a view in perspective illustrating a pole constructed in accordance With an embodiment of my invention; and

Fig. 2 is a sectional view taken longitudinally of the pole, the opposite ends of the pole being broken away.

As disclosed in the accompanying drawings 1 denotes the body of my improved pole consisting of an elongated member of predetermined dimensions and which is substantially L-shapcd in cross section. The body 1 is preferably formed of rolled steel.

Secured to the opposite faces of the body L are the reinforcing plates 2 and 3 extending from the lower end of the body 1 to a predetermined point inwardly of the opposite end thereof. Each of the plates 2 and 3 are successively of shorter lengths and are se cured to the body 1 through the medium of the rivets 4: or the like. It is to be noted that alternate plates 2 and 3 are substantially equally shortcnedso that the requisite and proportionate strengthening or reinforcing of the body 1 is retained. The lower portion of the pole has secured to the outer faces of the lower plates 2 and 3 the cast iron plates 5. The plates 5 are of such a length as to incase the portion of the pole which is embedded or set within the ground so that the body 1 and plates 2 and 3 which are also preferably made of steel, are effectively protected from corroding so that the life of the pole is materially prolonged. The lower end portions of the plates 5 are flush with the lower end of the body 1 and the plates 2 and 3 and the upper ends of the plates 5 are substantially flush. It is also to be noted that the flanges of the plates 2, 3 and 5 are of such width as to extend entirely across the flanges of the body 1.

Bolted as at 6 or otherwisesecured to the upper end portion is a cross bar 7 to which the lines are adapted to be engaged. Also suitably secured to the pole at predetermined points longitudinally thereof are the strips 8 extending beyond opposite sides thereof and which afford means whereby a lineman may readily ascend or descend the pole.

rom the foregoing description, it is thought to be obvious that a pole constructed in accordance with my invention is particu -larly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without materially departing from the principle and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A pole comprising an elongated membcr angular in cross section, imposed reinforcing members angular in cross section and secured to the opposite faces of the. pole and to each other and extending from the lower end. of the pole, the upper ends of the Patented June 25, 1918.

l plates terminating an equal distance below the upper. ends of alternate plates, the flanges of the plates being of a width to ex- I tend entirely across the flanges of the body.

f2. A .pole comprising an elongated'memher angular 1n cross section, and lmposed reinforcing members angular 1n CIOSSYSGCUOII and secured to the opposite faces of the pole and to each'other and extending from the the body and plates being formed of steel 15 and the casings of cast iron secured to the outer faces of the lower of thefirst named plates, said cast iron plates being angular in cross section with the flanges thereof of a width to extend entirely across the flanges 2c of the body.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

W. M. SMITH, E. H. NEWTON.
