DANIEL WARNER, OF BRONSON, MICHIGAN.

POST OR POLE.

SPECIFICATION forming part of Letters Patent No. 767,533, dated August 16, 1904.

: ., Application filed February .29,1904. Serial No. 195,948. (No model.)

,. To all whom it may concei'n:

Be it known that!, Daniel Warner, a citi• zen of the United States, residing at Bronson, • in the county of Branch and State of Michigan, 5 have invented a new and useful Post or Pole, of which the following is a specification.

‘ My invention relates to posts or poles, and has for its objects to produce a simple inexpensive device of this character which relaio tive to its size will be comparatively light in weight and at the same time exceedingly strong and durable.

To these ends the invention comprises the novel features of construction and combina15 nation of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a post embodying my invention. Fig. 2 is a transverse section on 20 the line 2 2 of Fig. 1. Fig. 3 is a similar view on the line 3 3. Fig. 4 is an elevation illustrating the device adapted for use as a telegraph-pole. Fig. 5 is a transverse section of the same on the line 5 5 of Fig. 4. Fig. 6 is 25 a view similar to Fig. 4, showing the device adapted for use as an electric-light or trolley pole. Fig. .7 is a detail section on the line 7 7 of Fig. 6.

Referring to the drawings, and particularly 30 to Figs. 1, 2, and 3, it will be seen that my improved post comprises a series of parallel upright members or wires 1 and a plurality of binding members or plates 2,through which the rods or wires 1 extend and by which they 35 are maintained in fixed spaced parallel relation.

The members 2, which may be of rectangular form, as herein shown, or of other suitable shape to accord with the desired cross40 sectional contour of the post, have their opposite or side faces 3 convexed, thereby materially strengthening them for the withstanding of transverse strains, while the vertical members 1 are preferably spaced uniform dis45 tances apart in lines parallel to lines radiating from the center of the plates 2, whereby transverse or lateral strains upon the members 1 are distributed uniformly over the surface of the plates 2 and the post as a whole is ren dered more rigid for the withstanding of lat- 50 eral strains than would otherwise be the case.

The post is provided with a base or groundengaging portion 4, consisting of a metal or other suitable web or filling which in the production of the post is cast or otherwise formed 5 5 integral with the two lower members 2 and completely fills the spaces or interstices between the rods or members 1, as seen more clearly in Fig. 3, attention being directed to the fact that this web or filling unites and con- 60 stitutes a connection between the said lower binding members 2 and has the adjacent portions of the vertical rods embedded directly therein.

In the construction of the post the rods or 65 wires 1 are arranged in the desired spaced relation within a suitable mold in which the binding-plates 2 are cast. The proper spaces in the mold for the formation of the plates are then filled with molten metal, which coming in a 70 highly-heated state into contact with the rods 1 partially fuses and integrally unites with the latter, thereby binding the wires firmly together and obviating movement of the plates longitudinally thereof. 75

In Figs. 4 and 5 I have adapted my device for use as a telegraph-pole, in which 5 designates the cross arm or beam, carrying the insulators 6 of usual form and with which the wires are engaged. The arm 5, which is com- 80 posed, preferably, of angle-iron, is provided with a longitudinal slot 7, in which the marginal edge of one of the members 2 seats, and beneath the slot with a pair of perforations 8, designed to receive, respectively, the ends of 85 a clamping member or bolt 9, which embraces the post for securing the arm thereto, the ends of the tie-band being held by suitable nuts tapped thereon and bearing upon the outer face of the arm, it being obvious that a proper 90 manipulation of the nuts will cause the band to bind tightly upon the post for securing the arm rigidly thereon.

In Figs. 6 and 7 the device is adapted for use as a trolley or electric-light pole by means 95 of an arm 11, secured thereto in a manner identical with that just described, this arm being, however, extended only upon, one side of the a

767,533 post and provided at its outer end with a hook or analogous engaging member upon which the lamp or trolley-wire holder may be hung.

The poles illustrated in Figs. 4 and 6 are, 5 excepting in matter of proportion, identical in construction with the post above described.

From the foregoing it is apparent that I produce a strong and durable post, which at the same time will be exceedingly light and io one which may be readily manufactured at a comparatively small cost. In attaining these ends minor changes may be made in the details of construction herein set forth without departing from the spirit of the invention.
