POLE-BASE.

Specification of Letters Patent.

Application filed June 4, 1910.

Patented Aug. 9, 1910.

Seria1 No. 564,965.

To-all whom it may concern:

Be it known that we, ALBERT B. COOK and James M. MILLER, citizens of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, and Newtown Square, county of Delaware, and State of Pennsylvania, have invented certain new and useful Improvements in Pole-Bases, of which the following is a specification.

Our invention relates to improvements in pole bases, the object of the invention being to provide an improvedbase, which will rigidly hold various sizes of poles, and which will enable poles that have rotted in the ground to be utilized.

A further object is to provide an improved pole base which is especially designed for use with telegraph poles, and which is constructed to withstand the necessary strains and stresses of a device of this character, and which is extremely simple in construction, strong and durable in use.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1, is a view in vertical section illustrating our improvements. Fig. 2, is a view in section on the line 2-2 of Fig. 1. Fig. 3, is a perspective view of one of the angle brackets 10, and Fig. 1, is a perspective view of one of the bolts 15.

1, represents the bod of our improved base, which is preferaby of concrete, and we illustrate a preferable shape of such base, namely, one that widens toward its lower end to firmly anchor the body in the ground.

On the upper end of the base, our improved head 2 is fixed. The head is of metal, preferably a casting, which is cast around a rod 3, projecting down through the center of body 1 and provided with a head 4 at its lower end firmly anchoring the head 2 on the body 1. Head 2 is also provided with a plurality of downwardly projecting pins 5 embedded in the concrete body 1. The upper end of head 2 is made in the form of a circular plate 6 which is strengthened by integral webs 7. Plate 6, between the webs 7, is provided with four radial slots 8, extending from the outer edge of the plate, the desired length inward,

9, represents a pole to which angle brackets 10 are secured. Four of these angle brackets are provided, two of them being appreciably shorter than the others, the longer or higher brackets being positioned in the direction of greatest strain on the pole, and the longer brackets as well as the shorter brackets, are connected by bolts 11, whichare forced through the pole 9, and secured by nuts 12, firmly clamping the brackets at opposite sides of the pole. The inwardly projecting members of the angle brackets 10 are each provided with two angular openings 13, in which the angular portions 14 of vertical bolts 15 are positioned. The heads of these bolts 15 are located above the inwardly projecting members of the brackets, and the screw-threaded portions of the bolts 15 project through the slots 8 and nuts 16 are screwed onto the lower ends of these bolts 15, against the bottom face of plate 6, and rigidly secure the pole on head 2. It will thus be noted that regardless of the diameter of the pole 9, it may be secured u on the head 2, as the slots 8 will receive t e bolts 15 regardless of the diameter of pole 9, so that this structure is adapted for various sized poles, and will rigidly hold any of them for ordinary use.

Various slight changes might be made in the general form and arrangement of parts described without departing from our invention, and hence we do not limit ourselves to the precise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A device of the character described, comprising a concrete body, a metal head anchored on top of the concrete body, a horizontal plate on the upper end of said head having radial slots therein extending inward from the outer edge of the plate, integral strengthening webs on the head strengthening the plate, and means adapted to be secured in said slots for securing a pole on the head, substantially as described.

2. A device of the character described, comprising a concrete body, a metal head an chored on top of the concrete body, a hori zontal plate on the upper end of said head having radial slots therein extending inward from the outer edge of the plate, integral strengthening Webs on the head strengthening the plate, angle brackets constructed to be secured to a pole, bolts projecting through said angle brackets and held against turning therein, a plurality of bolts being provided in each angle bracket, the bolts of each bracket projecting through one of the slots in said plate, and nuts on the lower ends of said bolts screwed against the bottom of said plate, substantially as described.

3. A device of the character described, comprising a concrete body, a metal head anchored on top of the concrete body, a horizontal plate on the upper end of said head having radial slots therein extending inward from the outer edge of the plate, integral strengthening Webs on the head strengthening the 'plate, angle brackets constructed to be secured to a pole, bolts projecting through said angle brackets and held against turning therein, a plurality of bolts being provided in each angle bracket, the bolts of each bracket projecting through one of the slots in said plate, nuts on the lower ends of said bolts screwed against the bottom of said plate, a rod fixed to said head, embedded in said body and having a head at its lower end, and pins integral with said head and projected into said body, substantially as described.

In testimony whereof We have signed our 1 names to this specification in the presence of two subscribing Witnesses.
