Improvements in the Mode and Means for Making the Junctions of
Frames for Cycles, Motor Cars, and such like purposes.
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
to be as follows:-
My invention has for its object improvements in the mode and means for making
the junctions of frames for cycles, motor cars and such like purposes by which the
necessity for braizing, soldering and the like is prevented or nearly so and the junctions
are made in a strong, expeditious and simple manner.
In forming the junctions of frame work for the above named purposes I enlarge
the sockets at the back end into which the tube or other member is to he entered and
in which it has to be fastened. This enlargement may be an annular one or an oval or
oblong or other shape. After the end of the tube is placed in position say in a branch
socket of the head I enter into the inner end of the tube or ball or oval or oblong or wedge
shape drift and then force down behind it a mandril or forcing or expanding tool
which forces the wedge, ball, or other enlarging piece into the mouth of the tube and
so enlarges it until the tube fills up the back enlargement in the socket. Or I may
split the tube and place in the end a wedge piece or pieces to be forced forward by the
tool, and this wedge piece may be afterwards withdrawn or it may be left permanently
in the end of the tube and this wedge piece may be either a block split or partly split
or a liner tube or oval, oblong or other desired shape.

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 frames for cycles, motor car, and other such like purposes, by which
the necessity for brazing, soldering and the like is prevented or nearly so and the
junctions are made in a strong, expeditious and simple manner.
In forming the junctions of frame work for the above named purposes I enlarge the
sockets at the back end into which the tube or other member is to be entered and in
which it has to be fastened. This enlargement may be an annular one or an oval or
oblong or other shape. After the end of the tube is placed in position-say in a
branch socket of the head I enter into the inner end of the tube a ball or oval or
oblong or wedge shaped drift, and then force down behind it a mandril, wedge or
forcing or expanding tool which forces the wedge, ball or other enlarging piece into

in the sockets. Or I may split the tube and place in the end a wedge piece or pieces
to be forced forward by the tool and this wedge piece may be afterwards withdrawn or
it may be left permanently in the end of the tube and this wedge piece may be either
a block split or partly split or a liner tube, or oval, oblong or other desired shape.
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 examples of my method of joining tubes with their sockets.
Figure 1 shews my method of joining the tube T with the socket S by forming the
back end s' of this socket larger than the mouth, and this enlarged end may be round,
oval, oblong, or other shape. After the tube has been inserted into the socket it is
expanded at the mouth t¹ so as to fill up the enlarged end of the socket by means of the
tool A which has an enlargement a' at one end and this end of the tool is forced into
the mouth of the tube by means of the wedge or mandril W as clearly shewn at
Figure 2 by which means the tube is securely held in the socket.
At Figure 3 I have shewn another method of expanding the mouth of the tube T in
the enlarged ends of the socket S. In this case after the tube has been inserted into
the socket I expand it by means of the ball B which is forced into the mouth of the
tube by the wedge W as clearly shewn at Figure 4, thereby securely fixing the tube
in the socket.
In some cases I split the end of the tube and insert a liner and expand it in the
socket by means of the small wedge in as shown at Figure 5 which when forced down
by the wedge W spreads the tube and liner apart and fills up the enlarged end of the
socket thus securely fixing the tube in its junction.
Or instead of the wedge w I may use the plug w which is inserted into the
enlarged end of the socket and then the mandril M is inserted in the junction as
clearly shewn at Figure 6 and by forcing the tube T into the socket the plug expands
the mouth thus filling up the enlarged end of the socket. The wedge and the
plug may if desired be left in the mouth of the tube and in order to reduce
the weight I may form the plug hollow as shewn at Figure 7 or the plug or small
wedge may be split or partly split and may be oval, oblong or other shape.
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 :-
First. The improvements in the mode and means for making the junctions of frames
for cycles, motor cars and such like purposes by forming the back end of the socket of
the junction larger than the mouth and then expanding the mouth of the tube in the
enlarged portion of the socket in the manner substantially as herein set forth and as
shewn upon the accompanying sheet of drawings.
Second. Securing tubes into their sockets or junctions by enlarging the back end
of the socket whether round oval or other shape and then expanding the mouth of the
tube so as to fill up the enlarged portion of the socket by means of a tool with an
enlargement at one end and a wedge shape tool in.the manner substantially as herein
set forth and as shewn upon the accompanying sheet of drawings.
Third. Expanding tubes in their sockets whether the end of the tube be split or
not by means of a wedge or solid or hollow plug either round, oval, or other shape in
the manner and for the purpose substantially as herein set forth and as shewn upon
the accompanying sheet of drawings.
