UNITED STATES PATENT l OFFICE.

FOSTER MILLIKEN, OF NEIV YORK, N. Y.

M ETALLIC POST.

SPECIFICATION forming part of Letters Patent No. 438,082, dated October 7, 1890. Application filed July 31, 1890. Serial No. 360,540. (No model.)

To all whom it may concern.-

Be it known that I, FOSTER MILLIKEN, of New York city, in the county and State of New York, have invented a new and useful Improvement in Metallic Posts, of which the following is a full, clear, and exact description.

My invention relates to an improvement in metallic posts; and the object of the invention is to provide a strong and durable post composed of but few parts and capable of being conveniently climbed when occasion may demand; and a further object of the invention is to provide a means whereby the interior of the post will be adequately ventilated and made capable of inspection and painting when desired.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 in a side elevation of a tapering post, illustrating the open-work thereof. Fig. 2 is an elevation of the closed side of the same. Fig. 3 is a transverse section through the post shown in Fig. 1, the section being taken below one of the tie-plates. Fig. 4 is a similar section illustrating a slight modification in the manner of attaching the sections of the post to the tieplates; and Fig. 5 is a transverse section through another modified form of post, in which the plates are dispensed with.

The post A is constructed of two or more segments 10, preferably two, which segments are provided at each side with a longitudinal ilange 11, extending outwardly at a right angle to the body, as is best shown in the sectional views.

IVhen a post is to be constructed as illus trated in Fig. 1 and in the sectional view, Fig. 3, the concaved surfaces of the segments are placed face to face, and at desired intervals in the length of the post inverted-U-shaped tie-plates 12 are introduced between the flan ges of the segments. The tie-plates, when made U-shaped in cross-section, as shown,

consist of a fiat table-section ot and longitudinal iianged sections a', which extend downward from the under face of the table, as shown in the end View of the plate in Fig. 1. When the post is to be tapering, the width of the plates is varied to assist in imparting such a contour; but when a post is to be straight throughout its length the tie-plates are of uniform Width.

Between the flanges of the tie-plates, near each end thereof, a tube 13 is introduced, and through the flanges of the segments and the anges of the tie-plates bolts 15 are passed, provided at one end With a head and at the other end with a suitable nut, or the said bolts may be provided with nuts at both ends.

Between the tie-plates, secured in position as above described, a series of tubes 16 isV placed between the flanges of the segments, and bolts or rivets 15 are passed through said flanges and the tubes, as illustrated in Fig. 1, from which it will be observed the completed structure affords upon two sides a perfect ladder.

In order to strengthen the segments 10 when they are of great length, a longitudinal rib 17 is formed integral with the central outer convexed section of the segments, as illustrated in Figs. 3, 4, and 5 and also in Fig.1; but the said strengthening-rib may be omitted or it may be employed when short posts are con structed.

In the form of post illustrated in section, Fig. 4, the bolts aresubstituted by rivets 18 where the tie-plates are secured to the segments and the tubes 13 are omitted, each flange of the segments being separately fastened to the flanges of the trusses.

In the form of construction illustrated in` Fig. 5 tie-plates are omitted and tubes 2O are interposed between the flanges of the seg` ments and studs 21 are passed through the flanges and tubes. When the studs are in position, their ends are headed in place, forming thereby a head at each extremity of the stud.

Having thus described my invention, I claim as new and desire to secure by Letters Patent@ 1. As an improved article of manufacture, a post consisting of longitudinal hanged seg- IOO segments, substantially as and for the pur-v pose specified.

3. In a metallic post, the combination, with opposed segments provided with longitudinal side anges and longitudinal strengtheningribs, of tie-plates or trusses, essentially U- shaped in cross-section, separating and spacing the segments, and rivets, bolts, or studs connecting the members of the tie-plates or trusses with the flanges of the segments, substantially as and for the purpose specified.

FOSTER MILLIKEN.
