PROVISIONAL SPECIFICATION.
Improvements in the Mode and Means for Making the Junction of
Tubes with their Sockets, applicable to the Framing of Cycles,
Motor Cars, and other Artioles.
1, EDWIN TAYLOR, of 1 Alfred Street, Warstone Lane, Birmingham, in the
County of Warwick, Stamper and Piercer, do hereby declare the nature of my said
invention to be as follows:-
My invention has for its object improvements in the mode and means for making
the junction of tubes with their sockets which is applicable to the frames of cycles,
motor cars, and other framing and prevents the necessity for the use of solder or
brazing.
In forming the end of a tube to be fastened in a socket or branch I form a little
distance from the end an external head or enlargement which forms an abutment
against the outer end of the socket and this head may be so dished at the shoulder as
to lap over the outside end of the socket so enclosing the outer end externally and
internally within itself. In other cases I may form the end of the tube with a conical
or taper part with the socket larger at the entrance to receive it. In either of the
cases after the tube is entered and home the inner end of the tube is enlarged by a
ball and wedge or mandril put down the junction tube. The ball may be formed on
and be a part of the wedge or tool with an inclined back to receive a wedge or other
tool to drive or force it into the mouth of the tube. I may also form the shoulder by
making the tube slightly elliptical and the mouth of the socket bored to agree with it
and then the inner end of the tube enlarged or made round to fasten it in position.
Sometimes I leave the end of the branch socket not pierced and use the unpierced
portion to form a bulge in the end of the tube and this may be made easier by
nicking the part to be bulged with a saw or other tool.

COMPLETE SPECIFICATION.
Improvements in the Mode and Means for Making the Junction of
Tubes with their Sockets, applicable to the Framing of Cycles,
Motor Cars, and other Articles.
I EDWIN TAYLOR of 1, Alfred Street Warstone Lane, Birmingham in the
County of Warwick, Stamper and Piercer, do hereby declare the nature of my said
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 has for its object improvements in the mode and means for making
the junctions of tubes with their sockets which is applicable to the frames of cycles
motor cars and other framing and prevents the necessity for the use of solder or
braizing.

page_text: In forming the end of a tube to be fastened in a socket or branch I form a little
distance from the end an external head or enlargement which forms an abutment
against the outer end of the socket and this head may be so dished at the shoulder as
to lap over the outside end of the socket so enclosing the outer end externally and
internally within itself. In other cases I may form the end of the tube with a conical
or taper part with the socket larger at the entrance to receive it. In either of the
cases after the tube is entered and home the inner end of the tube is enlarged by a
ball and wedge or mandril put down the junction tube. The ball may be formed on
and be a part of the wedge or tool with an inclined back to receive a wedge or other
tool to drive or force it into the mouth of the tube. I may also form the shoulder by
making the tube slightly eliptical and the mouth of the socket bored to agree with it
and then the inner end of the tube enlarged or made round to fasten it in position.
Sometimes I leave the end of the branch socket not pierced and use the unpierced
portion to form a bulge in the end of the tube and this may be made easier by
nicking the part to be bulged with a saw or other tool.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated my mode of making the junction of tubes with sockets
or other tubes.
Figure 1 shews my method of joining the tube T with the junction J by forming
the external head or enlargement a short distance from the end so as to butt
against the outer edge of the socket S and this enlargement may be dished so as to
overlap the outside end of the socket as clearly shewn at Figure 3 thus enclosing it
externally and internally. The enlargement may be stiffened by inserting one of
the well known extensible discs. After the tube has been inserted into the socket the
inner end is enlarged by the tool B which has an enlargement 6' at the end and
the wedge tool W by which means the part 6' is forced into the mouth of the tube
and expands it as clearly shewn at Figure 2. Or I may expand the mouth of the
tube by means of the ball 6 and wedge as shown at Figure 7. A pin p' may be
used as an extra security for preventing the tube from turning in the socket.
In some cases I may make the end t of the tube slightly cone shaped as shewn
at Figure 4 and bore the mouth s¹ of the socket to suit as shewn at Figure 5 and
after the tube is inserted the mouth is expanded in the manner as previously
described and as clearly shewn at Figure 6. Or the end of the tube may be formed
eliptical or other shape than round as shewn at Figure 8, and the mouth of the
socket formed to correspond as shown at Figure 9 so that after the tube is inserted
and the mouth expanded and made round it is impossible for it to move. In order
to facilitate the expansion of the mouth of the tube I may form one or more saw
cuts at the top.
In the modification as shewn at Figure 10 I leave the end of the socket
unpierced, and use this unpierced portion to form a bulge in the mouth of the tube
and in order to facilitate this I may form one or more saw cuts in the part to be
bulged.
Figure 11 shews my method of securing the tabe T in the junction J. The
tube T is first secured in the socket as hereinbefore described and the tube T inserted
into the junction and then the part t4 which may or may not have one or more saw
cuts is bulged into the mouth of the tube T by which means it is securely held in the
junction.
The joints may be filled in with any kind of cement or the end of the tube and
the inside of the junction and socket may be coated with tin, and heated after
the tube is inserted by which means the tube is soldered or sweated into the junction
and socket.
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 1
claim is :-
First. Forming the junctions of tubes with their sockets by expanding the mouth

page_text: of the tube after it has been inserted into its socket in the manner substantially as
herein before described and as shewn upon the accompanying sheet of drawings.
Second. Securing tubes into their sockets by expanding or flattening out the
mouth of the tube after it has been inserted into its socket by means of a tool with
an enlargement at one end and a wedge shaped tool or a ball or any suitably shaped
wedge piece and a wedge shaped tool in the manner substantially as herein set forth
and as shown upon the accompanying sheet of drawings.
Third. Socuring tubes into their sockets and junctions by expanding the mouth of
the tube in its socket and bulging out that part of the tube in the junction directly
over the socket substantially as herein set forth and as shewn upon the accompanying
drawings.
Fourth. The improvements in the mode and means for making the junctions of
tubes with their sockets substantially as hereinbefore described and as shewn on the
accompanying sheet of drawings.
