METAL POST OR COLUMN.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed April 18, 1908. Serial No. 421,799.

To all whom it may concern:

Be it known that I, SAMUEL H. TYsoN, a citizen of the United States, residing at Zanesville, Muskingum county, State of Ohio, have invented an Improvement in Metal Posts or Columns, of which the following is a specification.

My invention is an improvement in skeleton iron or steel posts or columns, particularly such as are intended and adapted for use as poles and supports for telegraph Wires.

The details of construction, arrangement, and combination of parts are as hereinafter described, and illustrated in the accompanying drawing in which Figure 1 is a side elevation of my improved post or column. Fig. 2 is a vertical section of the same. Fig. 3 is a horizontal section on the line 33 Fig. 2. Fig. 4 is an enlarged horizontal section on the line 4-4 Fig. 1. Fig. 5 is a horizontal section on the line 5-5 of Fig. 1.

The skeleton portion of my improved post or column is formed of a hollow central rod 1, and a series, preferably four, of smaller rods 2 which surround the central one and are spaced therefrom as indicated in several figures. The central rod 1 is screwed into a metal base 3, and the side rods 2 are attached to pins 4. arranged horizontally. The base 3 is inserted in the center of a concrete block 5, and the pins 4 enter the same and are provided exteriorly with nuts for holding in place the eyed ends of the rods 2. The concrete base 5will ordinarily be set to about one-half its depth in the ground, as indicated in Figs. 1, 2, the pins 4 being above the surface. The base 5 is reinforced by vertical iron rods 6, as shown in Fig. 2. The

several rods

1 and 2 are connected at the top by a head 7 and secured by nuts 8 applied above and below the same to the threaded ends of the rods.

At two or more points in their length, the

several rods

1, 2 are connected by transverse ties or braces 9, the same having eyes or loops for embracing the rods in the manner shown in Fig. 4. The two front rods 2 are also connected by transverse bars 10, as indi cated in Fi s. 1, 2, by which the skeleton structure is further strengthened and braced, while the said bars 10 serve as the rungs of a ladder for ascent and descent. Turn buckles 11 are applied to all the rods 2 at a point near the concrete base 5 and serve as means for adjusting and regulating the tension of the rods and therefore increasing the ri idity of the skeleton superstructure as a who e.

To the upper ortion of the post or column proper, and to t e two front rods 2, I apply a bracket or bar 12 which is secured to the rods 2 by means of screw-hooks 13, see Fig. 3. An obtuse-angle brace 14 is connected at its ends with the ends of the bracket 12 and at its angle to the central rod 1, the means of connection at this point being a hook 13, similar to the hooks 13, shown in Fig. 3.

It is apparent that by this construction, arrangement, and combination of parts, the bar or bracket 12 is held rigidly in place, and yet adapted for convenient vertical adjustment, it being only necessary to loosen the nuts of the bolts 13, 13, in order to raise or lower the bracket.

It will be seen that by the construction and combination of parts illustrated and described, the skeleton superstructure or post pro er, is adapted for attachment to, and detac ent from, the base 5, as conditions require.

The post is strong, ri id, comparatively chea and the concrete base forms a practical y indestructible foundation.

What I claim is:

The combination with a concrete base having a central metal socket and lateral screw-pins provided with nuts, of the metal superstructure constituting a 0st proper, the central rod of such post eing screwthreaded and adapted to connect with the said socket, and a series of other rods surrounding the central one but spaced therefrom and provided at their lower ends with eyes adapted to engage the aforesaid pins, as described.

SAMUEL H. TYSON.
