PROVISIONAL SPECIFICATION.
Improvements in and relating to the Jointing of Metallio Pipes
or Tubes.
We A. & J. STEWART & CLYDESDALE LTD.,. Tube Manufacturers, of
41 Oswald Street, in the City. and County of Glasgow, and JOHN WOTHERSPOON,
Engineer, of Gartsherrie Cottage, Coatbridge, Lanarkshire, do hereby declare the
nature of our invention to be as follows:-
This invention has reference to improvements-in and relating to the jointing, of
pipes or tubes formed-of-iron, steel, or other metal, and has for its object to form a
combined socket and flange joint where lateral motion will be. prevented..
In. carrying these improvements into. practice under one arrangement the two
adjacent ends of the pipes. or tubes to be jointed would be formed with-holes,
recesses, or grooves, and-a.connecting bar or strips formed with projecting pins or
staples would be fitted over the joint for the pins to enter these recesses; or two or
more of such bars may be similarly fitted. A ring, or collar would be fitted to slide
over the joint.and be formed: with recesses to pass over the bar or bars, and; thus
formia secure joint..
-
Loose flanges would be fitted over the pipes at the ends of the ring-with grooves
to receive india rubber or like rings and these flanges be bolted together to form a
fluid tight joint.
By an-alternative arrangement raised.or ridged parts may be formed near the
adjacent. ends of the pipes to be jointed, or projecting rivets, studs, or pins,-may.. be
fitted through these pipes, and in either case enter grooves formed. in the annular
jointing ring; and the ridges-and. grooves, may be either straight, angled, curved,
oriserewithreaded...
By a further arrangement the ends of the tubes are locked together. by. having
internal screw threads and screwing the. one into the other, and have the socket
sleeve over these with the connecting. flanges at its ends. Or the ends of the tubes
may be formed with screw threads on outer surface, aud.the socket sleeve be-formed
with screw threads on-inner surface. so as to screw over these, while the bolted
flanges and packing will make this a fluid tight joint. Or instead of screwing, the
ends of the tubes:may be checked into each other to form.a.tongue, dovetail, or like
locking device, and with the outer sleeve and bolted flanges and packing form a
fluid-tight.joint.

.. We, A. & J. STEWART & CLYDESDALE, LTD., Tube Manufacturers, of
41 Oswald Street, in the City and County of Glasgow, and JOHN WOTHERSPOON,
Engineer, of Gartsherrie Cottage, Coatbridge, Lanarkshire, do hereby declare the
nature of our invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement in writing,
that is to say :-
This invention has reference to improvements in and relating to the jointing of
tubes or pipes formed of iron, steel, or other metal and has for its object to form a
combined socket and flange joint whereby lateral motion will be prevented and a
joint suitable for extreme pressures be secured.
And in order that our said invention and the manner of performing or carrying
same into practice may be properly understood, we have hereunto appended an
explanatory sheet of drawings in which the same reference letters are used to
indicate corresponding parts in all the figures where shown.
Figure 1 is a sectional elevation of the ends of pipes or tubes as jointed together
in accordance with one arrangement of our improvements. And
Figure 2 is a transverse section as taken on the line X-X of Figure 1.
Figures 3 and 4 and 5 and 7 are views corresponding to Figures 1 and 2 of
modified arrangements of our joint; while
Figure 6 is an elevation broken away, at right angles to Figure 5.
Figures 8 and 9 10 and 11, and 12 and 13 are views corresponding to Figures 1
and 2, illustrating further modified arrangements of our improved pipe or tube
-joints.
Referring to these drawings:
:-
In carrying these improvements into practice under one arrangement as shown in
Figures 1 and 2 the two adjacent ends A, A', of the pipes or tubes to be jointed
would be formed with recesses or grooves a and a connecting bar or strip a¹ formed
with projecting pins or staples a² as shown in Figure 2 would be fitted over the
joint A for the pins a¹ to enter these recesses a, and two or more of such bars a¹
may be similarly fitted. A ring or collar b would be fitted to slide over the joint
and be formed with recesses to pass over the bar or bars a' as shown in Figure 2
and thus form a secure joint against lateral motion.
.
Loose flanges c would be fitted over the pipes A A¹ at the ends of the ring b with
grooves to receive india rubber, lead or like rings c' and these flanges c be coupled
together by bolts to form a fluid tight joint.
By an alternative arrangement as shown in Figures 3 and 4 raised or ridged
parts a may be formed near the adjacent ends of the pipes A, A to be jointed, or
as shown in Figures 5 to 7 projecting rivets, studs or pins a may be fitted through
these pipes, and in either case enter grooves a' formed in the annular jointing
ring b; and the ridges and grooves may be either straight, angled, curved, or screw
threaded. The loose flanges c would be bolted together as in Figure 1.
By a further arrangement as shown in Figures 8 and 9 the ends of the tubes A A'
are locked together by having screw threads and screwing the one into the other
at A³, and have the socket sleeve b over these with the connecting flanges c bolted
together at its ends. Or as shown in Figures 10 and 11 the ends of the tubes A A¹
may be formed with screw threads on outer surface, and the socket sleeve b be
formed with screw threads on inner surface so as to screw over these at A³, while
the bolted flanges c and packing cl will make this a fluid tight joint. Or instead of
screwing, the ends of the tubes A A' may be checked into each other at A³ as shown
"

page_text: in Figures 12 and 13 to form a tongue, dovetail, or like locking device, and with
the outer sleeve b and bolted flanges c and packing c¹ form a fluid tight joint.
Having now particularly described and ascertained the nature of our said inven-.
tion and in what manner the same is to be performed we declare that what we
claim is :-
The jointing of metallic pipes or tubes in the improved manner substantially as
herein described in reference to and shown in the several figures of the accompanying
drawings.
