I THOMAS JONES of Netherton near Dudley in the County of Worcester Tube
Manufacturer do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN STANCHIONS FOR SUPPORTING THE DECKS OF SHIPS THE ROOFS OF
BUILDINGS AND FOR OTHER LIKE PURPOSES to be as follows:-
My invention has reference to stanchions made of wrought iron or steel which
stanchions as usually made consist of solid cylinders or bars having the same
diameter throughout. My invention consists of the improvements hereinafter
described whereby stanchions of wrought iron and steel are made much stronger
by the use of the same weight of metal than stanchions of the ordinary kind.
I will describe my invention in connection with a stanchion for ships.
In making a stanchion according to my invention I make it tubular and
I strengthen the middle part by an increased thickness of metal at that part.
This I effect either by making the body of the stanchion of a tube of wrought
iron or steel having throughout the same diameter both internally and externally
and fixing in the interior of the stanchion a tube of wrought iron or steel of about
one fourth the length of the stanchion or I make the body of the stanchion of the
same internal diameter throughout and of an external diameter increasing from
each end to the middle where the metal is thickest.
In carrying into effect the first method I employ for the strengthening piece a
length of tube of such a diameter that it is slightly too large to enter the body of
the stanchion while the latter is cold. I heat the body of the stanchion and thereby
increase its diameter so that the strengthening tube can be introduced and passed
to the middle of the body of the stanchion and by the cooling and shrinking of the
body the strengthening tube is fixed in its place. Or the said strengthening tube
may be fixed in its place by welding.
In carrying into effect the second method of strengthening the body of the
stanchion I give the required varying diameter to the exterior of the tubular body
by the process of rolling the rolls employed having grooves the figure of which is
the counter part of the external figure to be given to the body of the stanchion.

I THOMAS JONES, of Netherton near Dudley in the County of Worcester, Tube
Manufacturer do hereby declare the nature of my invention for "IMPROVEMENTS
IN STANCHIONS FOR SUPPORTING THE DECKS OF SHIPS THE ROOFS OF BUILDINGS
"
AND FOR OTHER LIKE PURPOSES and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement :-
My Invention has reference to stanchions made of wrought iron or steel, which
stanchions as usually made, consist of solid cylinders or bars having the same
diameter throughout.
My Invention consists of the improvements hereinafter described, whereby
stanchions of wrought iron and steel are made much stronger by the use of the
same weight of metal than stanchions of the ordinary kind.
I will describe my invention in connection with a stanchion for ships.
In making a stanchion according to my invention I make it tubular and
I strengthen the middle part by an increased thickness of metal at that part.
This I effect either by making the body of the stanchion of a tube of wrought iron
or steel having throughout the same diameter both internally and externally, and
fixing in the interior of the stanchion a tube of wrought iron or steel of about one
half the length of the stanchion; or I make the body of the stanchion of the same
internal diameter throughout and of an external diameter increasing from each end
to the middle, where the metal is thickest.
In carrying into effect the first method, I employ for the strengthening piece,
a length of tube of such a diameter that it is slightly too large to enter the body of
the stanchion while the latter is cold. I heat the body of the stanchion and
thereby increase its diameter so that the strengthening tube can be introduced and
passed to the middle of the body of the stanchion and by the cooling and shrinking
of the body the strengthening tube is fixed in its place. Or the said strengthening
tube may be fixed in its place by welding.
In carrying into effect the second method of strengthening the body of the
stanchion, I give the required varying diameter to the exterior of the tubular body
by the process of rolling, the rolls employed having grooves the figure of which is
the counterpart of the external figure to be given to the body of the stanchion.
In each end of the tubular body of the stanchion I fit a head or terminal piece of
a shape suitable to fit on the beams or other parts of the structure in which the
stanchions are to be employed. These heads or terminal pieces are made either of
steel, cast iron or malleable iron, and have stalks or stems which enter the ends of
the body of the stanchion and are fixed by shrinking the said ends on the said
stalks or stems. The heads or terminal pieces may be further secured by cross
pins passing through the ends of the body and stalks of the terminal pieces and
riveted in position.
The application of my improvements to stanchions other than ship's stanchions,
differs in no essential respect from their application to ship's stanchions as herein
described.

page_text: Figures 1 and 2 of the accompanying Drawing represent elevations taken at
right angles to one another of a tubular stanchion constructed according to my
invention and Figure 3 represents in plan and elevation a portion of the same
drawn to a larger scale.
a is the tubular body of the stanchion made of an iron or steel tube of the same
diameter throughout, and b. b. are the heads or terminal pieces of the stanchion
made of steel, or cast iron or malleable iron. Each head b has a projecting hollow
stalk b and an annular recess or socket at c onto which stalks the ends of the
tubular body a are fitted, the extreme ends of the said tubular body a passing into
the annular recesses or sockets at c. (see Figure 3). The ends of the tubular body a, 1
are fixed on the heads b. b. by shrinking the former upon the latter; or the said
hollow heads may be fixed to the ends of the tubular body by cross pins or bolts
passing through the said ends and the stalks of the heads.
The top head b of the stanchion is secured to the girders by the screw bolts and
nuts at ff. and the bottom head of the stanchion is secured to the girder g by
screw bolts and nuts at h. h. passed through the flanges on the said girder and head.
Figure 4 represents another tubular stanchion constructed according to my
invention. In this stanchion the tubular body a is strengthened internally at its
middle by the strengthening tube a² (indicated in dotted lines) fixed in its place
by shrinking or by welding. The diameter of the tubular body of this stanchion
increases from each end to the middle, where its diameter is greatest, the
strengthening tube a² having a corresponding figure. Or a parallel tubular body
of the kind represented in Figures 1 and 2 may be strengthened at its middle by
an internal tube.
Or the tubular body may be strengthened by increasing the thickness of the
metal at and about the middle, that is, the body may have the same internal
diameter throughout and have an external diameter increasing from each end to
the middle, where the metal is thickest. This form of tubular body has an
external configuration similar to that of Figure 4.
The ends of the stanchion Figure 4 are shrunk upon the stalks of the heads and
are further secured by the screw pins and nuts at i.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that I claim
as my Invention of "Improvements in stanchions for supporting the decks of
ships, the roofs of buildings and for other like purposes,"
Making stanchions of a tubular body having heads or terminal pieces connected
to its ends substantially as berein before described and illustrated in the accom-
panying drawing, and when required strengthening the tubular body of the
stanchion in the ways described and illustrated.
