PROVISIONAL SPECIFICATION.
Improved Means for Joining Tubes, Rods and the like Together
or to Other Objects.
I, ROBERT GORDON of Suffolk House, Laurence Pountney Hill, in the City of
London, Engineer, do hereby declare the nature of this invention to be as follows
My invention relates to improved means for securing together the abutting
ends of pipes, tubes, rods, and the like, or for securing a pipe, tube, rod or the like to
a flat or other object.
To this end I form a fixed collar on the end of the tube or rod by upsetting,
The collar end of the tube or rod abuts against
casting, welding, or by other means.
or is received into a somewhat similar arrangement on the end of the tube, rod, or
object which is to be joined thereto. The exterior face of the collar I preferably form
at an angle to the pipe, though other shapes may be given to it, and over it is slipped
or sprung a split, loose sleeve which may be in one or more pieces, and is shaped to
correspond therewith, while over the sleeve I place a loose flange just large enough to
pass over the fixed collar, having its interior face shaped to correspond with the
exterior of the sleeve. This flange is secured by bolts to a similar flange on the other
tube, or to the object to which the tube or rod is to be fastened, so that the tightening
up of the nuts will press the two together, and consequently through the angle faced
sleeves will draw the end of the tube tightly on to the object to which it is to be
fastened. I may employ other forms of loose sleeves than the angle faced ones
described as long as the interior of the flange and the exterior of the sleeve and
collar are shaped approximately to correspond therewith.
Tubes having fixed flanges are liable to be spoiled by the breaking of the latter,
while they take up considerably more room in packing than do tubes with loose
flanges as described, which of advantage especially for shipment.

COMPLETE SPECIFICATION.
Improved Means for Joining Tubes, Rods and the like Together
or to Other Objects.
I, ROBERT GORDON of Suffolk House, Laurence Pountney Hill, in the City of
London, 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 :-
My invention relates to improved means for securing together the abutting ends
of pipes, tubes, rods, and the like, or for securing a pipe, tube, rod, or the like to a
flat or other object.
To this end I form a fixed collar or lug of comparatively small projection, but large
enough and strong enough to serve as abutments for the sleeves hereinafter described,
on the end of the tube or rod by upsetting, casting, welding, or by other means.
The collar end of the tube or rod abuts against or is received into a similar or a
female collar or recess, on the end of the tube, rod, or object which is to be joined
thereto. The exterior face of the collar I form at an angle to the pipe, though other
shapes may be given to it, and over it is slipped or sprung a split, loose, sleeve
which may be in one or more pieces, and is shaped to correspond therewith, while
over and behind the sleeve I place a loose flange just large enough to pass over the
fixed collar, having its interior face shaped to correspond with the exterior of the
sleeve. In practical work the flange will naturally be first placed on the tube and

page_text: the sleeve placed beneath it. This flange is secured by bolts to a similar flange on
the other tube, or to the object to which the tube or rod is to be fastened, so that the
tightening up of the nuts will press the two together, and consequently through the
angle faced sleeves will draw the end of the tube tightly on to the object to which it
is to be fastened. I may employ other forms of loose sleeves than the angle faced
ones described, as long as the interior of the flange and the exterior of the sleeve and
collar are shaped approximately to correspond therewith.
Tubes having fixed flanges are liable to be spoiled by the breaking of the latter,
while they take up considerably more room in packing than do tubes with loose
flanges as described, which is of advantage especially for shipment.
In order that my invention may be clearly understood reference is made to the
accompanying drawings which illustrate the manner in which my invention may be
applied to tubes or rods and from these its application to other objects may be readily
understood without special description.
Figures 1 to 4 shew one arrangement of my invention, Figure 1 being a section of
the complete joint, Figure 2 a plan of the divided sleeve, Figures 3 and 4 respectively
a cross section and plan of the loose flange. The pipes A A are in this case male
with collars or lugs B B of rectangular form, projecting sufficiently from the pipe to
afford a strong abutment for the sleeves C which may either be made in two halves
as shewn or be split on one side only so as to be sprung over the collars B. The
sleeve is in this case made with a flange a projecting at right angles a certain distance
beyond the collar B.
The loose annular flanges D are of such an internal diameter as just to pass over
the collars B of the pipes. Thus for joining the two pipes the loose flanges D are
first passed over the collars B on to the pipes, the sleeves C are then placed or sprung
in position behind the collars, and the flanges D being then made to abut upon the
flanges a of the sleeves, they are secured together by screw bolts as shewn, forming
as effective a joint between the pipes A A. as though the flanges D) were formed in one
therewith.
.
Instead of forming the collars B B of rectangular shape they may be made with
an angular or curved surface, the sleeve being in that case made with a
corresponding angular or curved inner surface as shewn in section and plan at
Figures 5 and 6 and at 7 and 8 respectively. The outer surface of the sleeve C may
in this case be either formed with a rectangular shoulder for the rectangular inner
surface of the flange D to bear against or the outer surface of the sleeve may also be
inclined or curved as shewn, the flanges being in that case made with a corre-
spondingly shaped inner bearing surface.
Figures 9 and 10 shew a section and plan of a modified form of the sleeve (shewn
at Figures 1 and 2 the flange a of the sleeve being made with a cylindrical
projection of such an internal diameter that it will just fit over the periphery of
the collar B, and extending sufficiently beyond it to cover the joint of the two
collars, so as to afford additional security against leakage through the joint.
The flange a of the other sleeve would in that case be made without such
cylindrical projection.
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. The combination of a pipe or rod A having collar or lug B with loose sleeve C
abutting on collar, and loose flange D secured by bolts.
2. The improved means for joining tubes rods and the like substantially as described
and illustrated in the drawings.
