COMIT LEIN SPECIFICATION.
Improvements in Metallic Posts.
1, FOSTER MILLIKEN, of 55, Liberty Street, in the City, County and State of
New York, United States of America, Commission Merchant, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to improvements 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. A further
object of the invention is to provide means whereby the interior of the post will be
adequately ventilated and rendered capable of being inspected and painted 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 part of this
specification, in which Figure 1 is a side elevation of a tapering post, illustrating the
open work thereof. Figure 2 is a side elevation of the closed side of the same.
Figure 3 is a transverse section through the post shewn in Figure 1, the section
being taken below one of the tie-plates. Figure 4 is a similar section, illustrating a
slight modification in the manner of attaching the sections of the post to the
tie-plates, and Figure 5 is a transverse section through another modified form
of post in which the plates are dispensed with. Similar figures and letter of
reference indicate corresponding parts in all the views.
The post A is constructed of two or more segments 10 (preferably two) which
are provided at each side with a longitudinal flange 11, of any facial contour,
extending outwardly at a right angle to the body, as is best shewn in the sectionaĺ
views.
When a post is to be constructed as illustrated in Figure 1 and in the sectional
view Figure 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 flanges of the segments. The tie-plates when made U-shaped
in cross-section, as shewn, consist of a flat table a and longitudinal flanged sections a¹
which extend downward from the under face of the table, as shewn in the end view of
the plate in Figure 1. When the post is to be made tapering, the width of the plates
is varied to assist in imparting such a contour, but when a post is to be made straight
throughout its length, the tie plates are of uniform width. It will be understood,
however, that the plates may be given any needed contour to impart a predetermined
side elevation or cross-sectional shape to the finished article.
Between the flanges of the tie plates, near each end thereof, a tube 13 is preferably
introduced and through the flanges of the segments and the flanges of the tie plates
bolts 15 are passed, provided at one end with a head and at the opposite 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 is placed
between the flanges of the segments and bolts or rivets 15" are passed through said
flanges and the tubes, as illustrated in Figure 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 of any cross-sectional or facial contour is formed integral
with the outer convexed section of the segments, preferably at the centre thereof,
as illustrated in Figures 3, 4, and 5, and also in Figure 1, but the said strengthening
rib may be omitted or it may be employed when short posts are constructed or

page_text: each section may be provided with more than one rib if in practice it is found
desirable.
In the form of post illustrated in section Figure 4, rivets 18 are substituted for the
bolts where the tie-plates are secured to the segments and the tubes 13 are omitted,
each flange of the segment being separately fastened to the flanges of the trusses or
tie plates.
In the form of construction illustrated in Figure 5, the plates are omitted and
tubes 20 are interposed between the flanges of the segments while 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.
I desire it to be distinctly understood that any equivalent of a bolt or nut may
be employed to unite the sections of the post.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;
1. As an improved article of manufacture, a post consisting of longitudinal
flanged segments united at their flanged portions in the manner substantially as
specified.
2. As an improved article of manufacture, a post consisting of longitudinal
flanged segments united at their flanged portions and provided with longitudinal
strengthening ribs, as and for the purpose specified.
3. As an improved article of manufacture, a post consisting of longitudinal
flanged segments united at their flanged portions by tubes, bolts, or equivalent
devices, as and for the purpose specified.
4. A metallic post, consisting of longitudinal flanged segmes, flanged tie plates
or trusses separating the segments, the flanges of the tie plates or trusses being
secured to the flanges of the segments, substantially as and for the purpose specified.
5. A metallic post, constructed in sections, the said sections being provided with
integral strengthening ribs, as and for the purpose set forth.
6. In a metallic post, the combination, with opposed seg its provided with
longitudinal side flanges, of spacing devices located between the opposed flanges
of the segments and bolts, studs, rivets, or their equivalents, connecting the flanges
of the segments with the spacing devices, substantially as describeu.
7. In a metallic post, the combination, with opposed segments provided with
longitudinal side flanges and longitudinal strengthening ribs, 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.
