Specification of Letters ?atent.

Patented Nov. 3, 1908.

Application filed September 30, 1907. Serial No. 395,270.

T 0 all whom it may concern:

Be it known that I, EDWARD H. \Vnnr WORTH, a citizen of the United States, residing at Rapid City, in the county of Pennington and State of South Dakota, have invented a new and useful Column, of which the following is a specification.

This invention relates generally to columns, and more particularly to one adapted for use in porch construction.

The object of the invention is to provide a light, cheap, and readily constructed column, which shall be thoroughly water-proof and thus highly durable, and one to which the porch rails can be readily secured at any point of its circumference.

With the above and other objects in View, as will appear as the nature of the invention is better understood, the same consists of the novel construction and combination of parts of a porch column, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in vertical longitudinal section of a porch column constructed in accordance with the present invention. Fig. 2 is a view in horizontal section taken on the line 22 of Fig. 1.

The column consists of a core 1, a plurality of bracing blocks 2 arranged therein, a shaft or jacket 3, a capital 4, and a base 5.

The core is constructed from a series of strips of wood, the meeting edges of which are beveled to provide close joints, and are rigidly secured to the bracing blocks 2 of which there are four shown in this instance, two being arranged intermediate of the ends of the core, and one at each terminal thereof. After the core members have been assembled, the rough core is placed in a turning lathe and turned down perfectly true and smooth, any desired degree of taper being imparted during this operation.

After the core is finished, the shaft or jacket 3 is slipped thereon, care being taken that the fit be exact. The shaft is constructed of sheet metal, the longitudinal edges of which are secured together by a lock-joint or seam 6.

The capital 4 and the base 5 may be made of any suitable material such as metal, wood, stone or concrete and may or may not be ornamented as preferred.

Secured to the terminals of the shaft and bearing respectlvely against the capital and the base are moldings 7 and S of any preferred character, and adjacent to the molding 7 is a third molding 9. These moldings are provided for the purpose of ornamentation, and as will be apparent, are not absolutely essential to the completed structure, but they are preferably employed as they will impart strength to the column terminals.

As the shaft will be of thin sheet metal it will be readily penetrable by nails so that porch rails can be secured thereto at any point in the circumference of the column.

The lock-joint 6 will have the seam members disposed on the inner side of the shaft. so that the exterior of the latter will present a smooth and unbroken appearance.

The column above described will be found strong and thoroughly efficient in construction, and, being water-proof by reason of the metallic shaft or jacket, will possess greater durability than the ordinary wooden column in common use. I

Having described the invention what is claimed is 1. A column frusto-conical in form comprising a hollow core consisting of a plurality of segmental members bracing-blocks to which the members are secured and a frusto-conical metallic casing arranged to be driven thereon to hold said segmental members firmly together.

2. A column comprising a hollow core consisting of a plurality of segmental members, circular bracing blocks to which the me1nbers are secured, and a frusto-conical metallic casing driven thereon.

3. A column comprising a frusto-conical body portion consisting of a plurality of segmental members, circular bracing blocks to which said members are secured, a frustoconical metallic casing arranged to be driven thereon and hold said segmental members firmly together, a capital, and a base secured to said body portion.

4. A column circular in cross section and comprising a frusto-conical core consisting of a plurality of segmental members, circular bracing blocks to which the members are secured and which are disposed, respectively, at the terminals of the core and at intermediate points thereof, a capital and a base secured to two of the blocks, and a frusto-conical metallic shaft 'or jacket in- I In testimony that I claim the foregoing closing the core and extending from end to as my own I have hereto affixed my signaend thereof arranged to be driven thereon, ture in the presence of two Witnesses.

the edges of the jacket being united by a lock EDWVARD H. WVENTVORTH. joint seam disposed on the inner side of the Witnesses: jacket, whereby its outer side Will present GEORGE WV. MENTCH,

a smooth and finished appearance. S. J. SORIBER.
