Improved Joints for Connecting Together Metallic Tubes or Pipes.
1, JOHN WOTHERSPOON of Clyde Tube Works, Coatbridge, in the County of Lanark,
North Britain, Tube Manufacturer do hereby declare the nature of this invention to
be as follows:
This Invention, which relates to improved flanged joints for connecting together
metallic tubes or pipes, has for its object to so construct the joints as to admit of their
being quickly and efficiently put together, and, quickly and easily disconnected; also
in cases where they have become fractured or broken, or it is desired for any other
purpose to disconnect them, the flanges, being in two or more parts, permit of this
being done quickly and simply without disturbing the pipes, whilst an advantage is,
that the connecting of flanges to pipes by screwed joints, or by brazing, or hard
soldering, is rendered unnecessary another advantage being obtained that in transit,
less room is occupied by the pipes and their connections.
The ends of the tubes to be jointed together in accordance with the present Inven-
tion, are formed with small flanges or collars, between any contiguous two of which, a
leather, asbestos, or equivalent washer is placed.
Under one arrangement these flanges are forced together by annular projections
formed on collars, which are constructed in two parts, and the outer surfaces of which
are so checked and otherwise formed as to fit into, and engage with, the inner
correspondly shaped surfaces of surrounding flange rings. These flange rings are
drawn towards each other by screwed bolts and nuts, and the central openings thereof
are of such size as allow them to pass easily over the smaller flanges of the tubes.
In place of the inner rings, hereinbefore mentioned, the small flanges of the tubes
may be forced together by means of projections formed on the inner faces of the flange
rings, which, under this arrangement are each constructed in two parts. These two
parts may obviously be fitted together in many different ways and, as examples of
such various methods, there may be enumerated the following
First. Each of the two parts is formed with a flange at right angles to itself, these
Hanges being secured together by bolts and nuts. The thus-constituted flanges are
thus free to be forced together by bolts and nuts or other equivalents.

page_text: Secondly. One of the two parts is formed to overlap the other, the two parts being
held together by the bolts and nuts employed for making the joint.
Thirdly. One of the two parts is formed with a recess, into which a correspondingly
shaped projection upon the other part, is secured by the bolts and nuts employed for
making the joint.
Lastly. The outer faces of the two parts at their meeting edges are provided with
projections which fit into recesses formed in the underside of the heads of the bolts,
which, under this construction, are therefore arranged; when four are used, two with
their heads upon one flange, and two upon the other flange, that is to say, two bolts
inserted from the right-hand, and two inserted from the left-hand, of the flanges.

Improved Joints for Connecting Together Metallic Tubes or Pipes.
I, JOHN WOTHERSPOON of Clyde Tube Works, Coatbridge, in the County of Lanark,
North Britain, Tube Manufacturer, 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, which relates to improved flanged joints for connecting together
metallic tubes or pipes, has for its object to so construct the joints as to admit of
their being quickly and efficiently put together, and quickly and easily disconnected ;
also in cases where they have become fractured or broken, or it is desired for
any other purpose to disconnect them, this being done quickly and simply without
disturbing the pipes, whilst an advantage is, that the connecting of flanges to pipes by
screwed joints, or by brazing, or hard soldering, is rendered unnecessary; another
advantage being obtained that in transit, less room is occupied by the pipes and their
connections.
The ends of the tubes to be jointed together in accordance with the present Inven-
tion, are formed with small flanges or collars, which when the joint is made and
enclosed within a pair of outer flanges and between any contiguous two of such small
flanges a leather, asbestos, or equivalent washer is placed.
In order that my said Invention may be properly understood and readily carried
into effect, I will now proceed to describe the drawings hereunto annexed.
Figure 1, is a side elevation or edge view, Figure 2, is a face view from one side,
and Figure 3, is a face view from the other or opposite side of an improved pipe joint
constructed according to one arrangement embodied under my present Invention.
Figure 4, is a section through the same and Figures 5 to 8 (inclusive) are elevations
of detached portions of the same all hereinafter more particularly described.
Figures 9 to 11 (inclusive) Figures 12 to 18 (inclusive) Figures 19 to 25
(inclusive) and Figures 26 to 31 (inclusive) are respectively views of four different
arrangements, which are shewn as examples of the means of constructing pipe joints
in accordance with a modification of my present Invention.
The ends of the tubes or pipes a and b which are to be connected together in
accordance with this Invention, are formed with the small flanges marked c and d
respectively, and between any contiguous two of which is placed a leather asbestos or
equivalent washer e, as represented at Figures 4, 11, 14, 22 and 28 of the annexed
drawings.
The means shewn at Figures 1 to 8 (inclusive) whereby the flanges c and d, are
forced towards each other for the purpose of making a tight joint, consist of the
collars and g, each of which as shewn more particularly in end elevation at
Figures 2, 3, 5 and 6 is formed in two parts, and a side elevation of one of the parts
of each of the said collars is shewn respectively at Figures 7 and 8. The interior
surface of the collar g, as shewn upon the annexed drawing is recessed so as to receive

page_text: the flanges c and d, and the collar f, is so formed that it is capable of pressing the
said flanges into the before mentioned recess. The two parts of the collar f, fit into
the flange ring h,. the interior or central aperture through which is shaped out to
9, fit
correspond with the exterior of the said collar and the two parts of the collar
into the flange ring i, the interior or central aperture through which is shaped out to
conform with the exterior surface of the said collar y. It is to be especially observed
that the size of the beforementioned central apertures through the flange rings h and i
is such as admits of the said flange rings being passed over the pipe flanges c and d.
The two flange rings h and i, are drawn towards each other by the bolts and nuts j,
of which there may be two, three four or more sets.
In the means of constructing the pipo joints which are hereinafter described, the
beforementioned collars and y, are dispensed with, but the recesses and projections
which I have hereinbefore described as formed in and upon the adjacent faces of such
collars are replaced by corresponding recesses and projections formed on the flange
rings, which, under each of such arrangements is constructed in two parts.
In the improved pipe joint which I have represented in side elevation or edge view
at Figure 9, in face view at Figure 10, and in section at Figure 11, the two parts k
and of the flange rings are formed with the flanges m and n, respectively, these
One of the thus
flanges m and n, being secured together by the bolts and nuts o.
constituted flange rings is formed with a recess to accommodate the flanges c and d
while the other of such flange rings is formed with the projection p, which forces the
said flanges c, and d, tightly together and into the before mentioned recess.
flange rings with their respective joints arranged at right angles to each other are
drawn nearer together so as to make a tight joint by the bolts and nuts j, in a manner
similar to that herein before described with reference to Figures 1 to 4 of the annexed
drawings.
The two
In the improved pipe joint which I have represented in side elevation at Figures 12
in face view at Figure 13, in section at Figure 14 and the two parts of one of the
flange rings, of which are shewn in detached views at Figures 15 to 18 (inclusive) the
said two parts of each flange ring are made to overlap each other. With reference
more particularly to Figures 15, 16, 17 and 18 it is seen that the part q, is so formed
as to overlap the part 2, while at the inner side of the overlapping portions of the parts,
there are formed the tapered projections which fit into recesses of corresponding
form provided in the outer side of the part r. The parts y and r of the one flange ring
are provided with projections which together constitute the annular projection p for
forcing the pipe flanges c and d, into the recess formed for their accommodation in
the other flange ring. As shewn at Figures 12, 13 and 14, the bolts and nuts j, by
means of which the joint is tightened, serve to secure the parts of the flange rings
together, the joints of the said flange rings being respectively disposed at right angles
to one another as in the example herein last described and as in the example herein-
after described with reference to Figures 25 to 30 of the annexed drawings.
Another modification of the improved pipe joint is represented in side elevation at
Figure 19, in face view at Figure 20, in end elevation or plan at Figure 21, in section
at Figure 22, and the two parts of the flange rings of which are shown undetached at
Figures 23 and 24. In this joint the two parts of each of the flange rings are pro-
vided with the projections and recesses, into which such projections respectively
fit, Figures 23 and 24 are views of the inner face of the two parts of one of the
flange rings, and Figure 25, is an end view of one of such parts, the flange rings, it
is to be observed under this construction being preferably of elongated or oval form.
From these views it is seen that when the part which is represented at Figures 24
and 25 is fitted into the back of the part represented at Figure 23, the projection u
(Figures 24 and 25) enters the recess (Figure 23) and in the reverse manner the
projection u, which is represented in dotted lines at Figure 23, enters the recess v
Figure 24. In this way the two parts are locked together and two flange rings, one
provided with the hereinbefore described annular projection p, and the other with the
recess for accommodating the pipe flanges c and d, constitute the improved join
which may be tightened by the screwed bolts and nuts j.

page_text: I have represented another form of my improved pipe joint at Figure 25 in side
elevation, at Figure 27 in face view, at Figure 28 in section, and at Figures 29 and
30 I have represented in face view, as detached from the said joint, the two parts of
one of the flange rings thereof, one of such parts being represented in edge view at
Figure 31. In the construction of this joint, the two parts of each of the flange rings,
at their meeting edges are formed with the projections wc, and the heads of the bolts,
at the underside thereof, are recessed so as to fit over the said projections in the
manner indicated more particularly at Figure 28 of the annexed drawings. The
joints of each of the flange rings under this construction as in the examples represented
at Figures 9 to 18 (inclusive) are disposed respectively at right angles to one another,
and a tight joint may be ensured by screwing the nuts y along their respective bolts.
in the required direction.
At Figure 32 I have shewn in section and at Figure 33 in elevation a modifica-
tion of my improved joints in which the flanges a and b respectively are formed each
in a single piece of metal. Under this modification each flange is placed on the tube a
and d, respectively before the small flanges are formed in the respective tubes.
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 what I claim is :-
First. The improved joint for connecting together metallic tubes or pipes consisting
of the collars and g cach formed in two or it may be more parts, which fit into the
flange rings and i, the internal diameters or the diameter of the central openings
through which flange rings, is such as admits of them being easily passed over the
flanges c and d of the tubes a and b all substantially as and for the purposes herein-
before set forth with reference to Figures 1 to 8 of the annexed drawings.
Second. The improved joints for connecting together metallic tubes or pipes
wherein are employed two flange rings each composed of two parts which construction
admits of them being readily applied to or removed from such joints without dis-
turbing the tubes or pipes in which the said joints are made all substantially as and
for the purposes hereinbefore set forth with reference more particularly to the examples
shewn at Figures 9 to 31 (inclusive) or the mechanical equivalents thereof.
Third. The improved joint for connecting together metallic tubes or pipes, as
hereinbefore described and shewn at Figures 32 and 33 of the annexed drawings.
