PROVISIONAL SPECIFICATION.
Improvements in Joints of Tubes and Pipes.
We STEPHEN JAMES NORTON of Fern Villa Stopford Road Upton Manor
Essex and HORACE EDWIN NORTON of West Ferry Road Millwall in the County
of Middlesex Engineers do hereby declare the nature of this invention to be as
follows:-
Our invention relates to joints of tubes either wrot iron, steel, or cast iron, or
other metal, and has for its object to provide a simple, and ready form of fixing a
small size tube into a large sized one, vertically or horizontally and so that the
same when fixed vertically will be substantially rigid, and free from oscillation
from wind, easily fixed & with the least possible labour, & consists of a taper
casting having in itself four or more recesses, and fixed inside the larger tube by
means of bolts or rivets, and four or more taper wedge pieces fixed outside the
smaller tube in a like manner, the smaller tube when so fitted with wedge pieces
will then correspond with the recesses of the castings of larger tube, & then driven
tightly into the same & the joint when made & used as a vertical one, covered with
a moveable ornamental casting for appearance.

We STEPHEN JAMES NORTON of Fern Villa, Stopford Road, Upper Manor
in the County of Essex, Engineer and HORACE EDWIN NORTON of West
Ferry Road, Millwall in the County of Middlesex, Engineer 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:--
The invention has for its object to provide a simple and inexpensive means
whereby two tubes of different diameters may be readily fixed together in a
substantial and rigid manner so that a vertical column thus formed will be unaffected
by wind and free from oscillation.
In carrying the invention into effect a tubular casting is driven into one end of
the larger tube and if necessary there fixed by means of bolts or rivets and this
casting which is preferably of malleable iron is upon its interior formed with
several taper grooves or recesses.
At one end of the smaller tube and upon the exterior thereof are fixed by
rivetting or otherwise several taper or wedge shaped pieces of malleable iron or
other suitable material corresponding with and adapted to enter into the grooves
or recesses of the casting.
The two tubes fitted in the manner hereinbefore described are driven tightly
together when they will become firmly fixed against accidental displacement whilst
a loose casing is fitted over the joint in order to enclose the same and give an
ornamental appearance thereto.

page_text: In lieu of forming the wedge shaped pieces separately and fixing them to the
smaller tube by rivets they may be formed upon the exterior of a short tube or
cylinder adapted to be fixed with the smaller tube by rivetting or otherwise.
And in order that the said invention may be more clearly understood and
readily carried into effect we will proceed aided by the accompanying drawings
more fully to describe the same.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a portion of a post or column constructed according
to the present invention.
Figure 2 is a vertical section thereof.
Figure 3 is a plan thereof with the ornamental casing removed.
Figure 4 is a horizontal section taken on the line 1-1 of Figure 2.
Figure 5 is a similar view to Figure 2 representing a slight modification.
Figure 6 is a plan thereof.
Figure 7 is a horizontal section taken on the line 2-2 of Figure 5.
In the several figures in which like parts are indicated by similar letters of
reference Figures 3 and 4 and 6 and 7 are drawn to an increased scale with respect
to Figures 1, 2, and 5, whilst for the sake of clearness the ornamental casing is
removed in Figures 3, 4, 6, and 7.
Referring to Figures 1 to 4 a represents the larger tube, b represents the smaller
tube and c represents the ornamental casing which covers the joint.
a¹ represents a tubular casting which upon its exterior is formed cylindrical to fit
the bore of the tube a and this casting a' is tightly driven into position in the
tube a until arrested by the shoulder a engaging the end of the tube a and is thus
securely fixed therewith or if necessary it might be further secured by means of
bolts or rivets.
The casting a which is preferably of malleable iron is upon its interior formed
with several grooves or recesses a' and at one end of the smaller tube b and upon
the exterior thereof are fixed by rivetting or it might be otherwise several taper
or wedge shaped pieces 61 of malleable iron or other suitable material corresponding
with and adapted to enter into the grooves or recesses a³ of the casting a¹.
The two tubes ab fitted in the manner above described are driven tightly together
when they will become firmly fixed against accidental displacement whilst the loose
casing c is afterwards fitted over the joint in order to enclose the same and give an
ornamental appearance thereto.
In the example given at Figures 5, 6, and 7 the wedge shaped pieces 6¹ in lieu
of being formed separately and afterwards fixed to the smaller tube b by rivetting
or otherwise are according to this example formed upon the generally tapered
exterior of a short tube or cylinder * which is tightly driven onto and thus fixed
with the smaller tube b.
Although the invention is illustrated in connection with a vertical column such
as a lamp post a telegraph pole, a ventilating shaft for sewer gulleys or the like it
will be evident that it is equally applicable to tubes intended to be horizontally
disposed.
By the simple and inexpensive means herein before described two tubes of
different diameters may be readily and securely fixed together against accidental
displacement.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A means of joining together pipes or tubes of different diameters comprising
a tubular casting exteriorly adapted to be fixed in the interior of the larger tube
and interiorly provided with several tonered

page_text: pieces adapted to be fixed upon the exterior of the smaller tube and shaped to fit
said grooves or recesses substantially as herein shown and described.
2. A means of joining together pipes or tubes of different diameters comprising
a tubular casting exteriorly adapted to be fixed to the interior of the larger tube
and interiorly tapered or wedge shaped and a coacting exteriorly tapered casting
or castings adapted to be fixed upon the exterior of the smaller tube substantially
as herein shown and described.
3. A means of joining together pipes or tubes comprising two tubes of different
diameters an interiorly tapered tubular casting fixed in the interior of the larger
tube and an exteriorly tapered coacting casting or castings fixed upon the exterior
of the smaller tube substantially as herein shown and described.
4. A means of joining together pipes or tubes comprising two tubes of different
diameters an interiorly tapered tubular casting fixed in the interior of the larger
tube a coacting exteriorly tapered casting or castings fixed upon the exterior of
the smaller tube and a loose ornamental casing covering the joint substantially as
herein shown and described.
