page_text: I ELIAB Box of 289, Broadway, Bexley Heath, Kent, Architect and Surveyor, do
hereby declare the nature of this invention to be as follows:
The object of this invention is to secure tubes in sockets for various purposes in the
Arts, and the invention consists in the means employed for the furtherance of this
object.
In carrying out any invention, I employ sockets in which a series of internal
longitudinal taper grooves or flutes are formed in any convenient manner.
On the outer periphery of the tube end, corresponding grooves or flutes are formed,
and, in addition, two, three, or more saw-cuts are made in the end of the tube.
A wedge, hollow or solid, and slightly taper, is inserted in the end of the tube, and
the socket is placed over the end of the tube. The wedge is then driven into the tube
end, so as to force the spring ends of the tube outwards, and cause the grooves or
flutes in the pipe and socket to interlock. The parts can then be secured by a screw
or screws inserted from the outside.
The sockets may have a solid seating or back, in which case the driving on of the
socket will force in the wedge, but if a pipe joint is required, the hollow wedge will
be driven into position by a rod or otherwise.
Cement, glue, or other material, may be used to assist in making a sound joint.

ELIAB Box of 289 Broadway, Bexley Heath, Kent Architect & Surveyor 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:—
This invention relates to an improved mode of connecting tubular portions to
sockets for various purposes in the arts and the invention consists in producing the
joint without the aid of brazing screwing or any of the other methods heretofore in
use for this purpose. In the accompanying drawings I have shown, by way of example
in Figures 1 to 3 my invention as applied to connecting a tube to a solid ended
socket,,while Figure 4 illustrates the application of my invention for connecting
two tubular portions to a tubular socket, the said views being chiefly in section.
A represents a tube or pipe, B a socket which may however have an open end, and

page_text: Ca plug which may be solid or hollow or tubular. In the end of the pipe I form
longitudinal saw cuts a of suitable depth, and I bevel the edges of the saw cuts so as
to form a taper recess triangular in cross section at each saw cut, as shewn at a¹,
Figure 1. In the inner wall of the socket B, which is perfectly cylindrical internally,
I form taper grooves b, the greatest depth and the least width being at the back-
or it may be at the centre,--of the socket, with splayed edges. In this way I leave
taper ribs or projections triangular in cross section, as shown at 6', Figure 1. The
solid plug C in Figures 1 to 3 has a cylindrical part c, and a conical part c¹, the reason
for which will be presently explained, but in Figure 4. the plugs C and C, which are
shown hollow, will be coned, or tapered off in opposite directions externally. To
connect the parts, as in Figures 1 to 3, together, the cylindrical part c of the plug C
will be driven into the pipe end. The conical part c¹ is then inserted in the
socket B, taking care that the saw cuts a in the pipe A register with the points of
the taper ribs b, and the pipe is driven into the socket, or the socket on to the pipe,
or in the case of an open ended socket the conical part of the plug will be driven
into the pipe end by means of a suitable tool. The action of driving will, by reason
of the conical part c¹, cause the tongues a² formed by the saw cuts in the pipe to
open out and fill in the grooves.b, the bevelled edges of the recesses a¹at the same
time riding up and fitting on to the bevelled faces of the ribs b.. Thus, it will be
seen that the parts will interlock, and any tendency for the one to twist in or on the
other will be entirely obviated, and the joint will in all respects be sound and lasting.
In Figure 4 one pipe end, A', will be placed half way in the socket B, and one coned
plug C will then be driven in. The other coned plug C is then placed in the other
pipe end A, and this is placed in the socket and driven in to meet the first pipe end,
the tongues spreading out in the socket as before explained. This form of joint will
be admirably suited for connecting up cylindrical or other shaped pieces of all.kinds
which are likely to be subjected to a twisting strain, and for this reason will be useful
for various purposes in the arts as above mentioned.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1st. The mode of securing pipes or tubes in sockets, which consists in causing
parts of the pipes to interlock with parts of the sockets by the insertion of a conical
plug or wedge, as and for the purpose set forth.
2nd. The mode of securing pipes or tubes in sockets as herein described, and
consisting in saw cutting the end of the pipe, taper-bevelling the edges of the saw
cuts to form taper recesses, forming taper grooves on the inner wall of the socket, so
as to leave taper ribs or projections more or less triangular in cross section, or vice
versa, placing the pipe in the socket and forcing in a conical plug, to cause the
tongues formed by the saw cuts to open out and interlock with the ribs on the socket,
as and for the purpose set forth.
3rd. Securing hollow cylindrical or other shaped portions in sockets in the manner
herein shewn and described, whereby any tendency to twist or otherwise move is
overcome.
