Improvements in the Mode and Means for Making the Junctions of
Framing for Cycles, Motor Carriages, 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 framing for cycles, motor carriages and such like
purposes by which I obtain simple, cheap and effective junctions between the
number of frames made of tubing or wood or of the two combined and which
enables me in a great measure to dispense with braizing which has been found"
to be very objectionable as thick tubes are often made very brittle and there is
always a certain amount of uncertainty as to whether thin tubes are injured.
In uniting the one tube to another in framing junction sockets have been
fastened on one tube and the other put into a branch socket and then braized.
or soldered there. Now I effect my junctions by making sockets or their
equivalents by stamping, forging or casting a piece which forms the junction
in two halves and having a flange running round the junction which may be
afterwards clamped together over the tube or rivetted, bolted, screwed or some-..
times braized together. Such sockets or junctions may be stamped so as to bend
around the main member and only having junction flanges on the branch socket
or the socket may be made in two or three corner pieces fitting over and partly
round the tubes to be joined or secured by flanges on the top or edges or they.

over the same. Where clips are used over the flanges rivets or bolts may pass.
through both the clips and flanges and such lugs as the seat pillar lug may be,

The tubes may be enlarged at their inner ends to prevent them being withdrawn.

page_text: Improvements in the Mode and Means for Making the Junctions of
Framing for Cycles, Motor Carriages, 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 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 framing for cycles, motor carriages and such like
purposes by which I obtain simple, cheap and effective junctions between the
members of frames made of tubing or wood or of the two combined and which
enables me in a great measure to dispense with brazing which has been found
to be very objectionable as thick tubes are often made very brittle and there is
always a certain amount of uncertainty as to whether thin tubes are injured.
In uniting the one tube to another in framing junction sockets have been
fastened on one tube and the other put into a branch socket and then brazed
or soldered there. Now I effect my junctions by making sockets or their
equivalents by stamping, forging or casting a piece which forms the junction
in two halves and having a flange running round the junction which may be
afterwards clamped together over the tube or rivetted, bolted, screwed or some-
times brazed together. Such sockets or junctions may be stamped so as to bend
around the main member and only having junction flanges on the branch socket
or the socket may be made in two or three corner pieces fitting over and partly
round the tubes to be joined and secured by flanges on the top or edges or they
may be clamped by ferrules shaped out of solid tubing and driven or shrunk
over the same. Where clips are used over the flanges rivets or bolts may pass
through both the clips and flanges and such lugs as the seat pillar lug may be
made in three sections splitting the back stay lugs vertically as well as the socket.
The tubes may be enlarged at their inner ends to prevent them being withdrawn
as also the wood members which may be made larger at the ends or wedged out
and an inner shoulder may be formed in the socket pieces as a stop or stops to
prevent the tube entering too far. The tubes or wood members may be
round, oval, oblong or other section. The main bracket sockets or branches
may be constructed in a number of sections in like manner by stamping, forging
or casting. The tubes may be flanged up at the ends to hold them in or have a
collar shrunk on them.
In order that my invention may be more clearly understood and easily carried
into practical effect I have appended hereunto a double sized sheet of drawings
upon which I have illustrated several examples of my method of joining tubes
to their sockets.
Figure 1 is a front view of a bottom bracket of a velocipede constructed according
to my invention.
Figure 2 is an end view of Figure 1.
Figure 3 is a plan view showing the bottom half of the bracket.
Figures 4 and 5 are plan views of the top portions of the bracket.
Figures 6, 7, 8 and 9 shew further examples of my improvements.
In carrying my invention into practice I form the bottom bracket or main
junction piece in three parts A, B and C by stamping forging or casting, leaving
an external flange around each where they are united together. The part A,
which forms the bottom portion or underside of this main junction, has a screw
thread cut at either end to receive the cups or ball races, and the flanges a¹ are

page_text: drilled or provided with a number of holes as clearly shown at Figure 3. The
halves of the sockets a and a3 also have external flanges around their edges.
The part B which forms the left hand half of the top portion of this bracket
has the external flange b¹ formed around its edges to correspond with that portion
of the flanges a¹ upon which it fits and the holes in these flanges are formed to
correspond or come exactly opposite the holes in the flange a¹. The part C which
forms the right hand half of the top portion of this bracket has the external
flanges c¹ formed around its edges to correspond with the portion of the flanges a
and also with the flanges on the sockets D and E into which the seat pillar tube
and the tube which comes from the bottom ball head lug respectively fit. When
these sections have been placed together and the tubes inserted into their respec-
tive sockets, the parts B and C are rivetted, bolted or screwed to the part A
and together where the sockets D and E join as shown at Figures 1 and 2. The
tubes before being inserted into their sockets may be enlarged at their inner
ends to prevent them being withdrawn, as shown at Figure 8. An inner shoulder
may also be formed in these sockets so as to prevent the tubes entering too far.
At Figure 6 I have shown the seat pillar lug or junction piece F which forms
part of a bicycle frame formed in three parts G, and then rivetted together after
the top tube and seat pillar tube have been inserted into their respective sockets.
At Figure 7 I have shown a modification of my improvements. In this case I
form the lug H as shown in two parts with the flange h¹ around where the edges
meet. I then place the collars H2 and H on the end of the sockets and these
collars are provided with flanges and rivet holes to correspond with the flanges
and rivet holes on the sockets of the lug. After the tubes have been placed in
position the parts are rivetted together.
In the modification as shown at Figure 9 instead of forming flanges on the
edges of the parts of the lugs whether in two or more parts, I first place the tubes
into their sockets and then drive or shrink the ferrules J J and J2 on to the
ends of the sockets, thus firmly and securely fixing the tubes in position. Or
the parts of the junction piece may be clamped together.
In some cases the ends of the tubes before being inserted into the sockets of
the lugs or brackets may be flanged or have a ferrule or collar shrunk on to
their ends.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
CLAIMS.
First. Forming junction pieces or brackets in two or more parts with external
flanges and rivetting, bolting or screwing the same together in the manner sub-
stantially as hereinbefore described and as shown upon the accompanying sheet
of drawings.
Second. Junction pieces or brackets formed in two or more parts and joined
together by ferrules or clamp in the manner substantially as hereinbefore described
and as shown upon the accompanying sheet of drawings.
Third. The improvements in the mode and means for making the junctions of
framing for cycles, motor carriages, and such like purposes substantially as here-
inbefore described and as shown upon the accompanying sheet of drawings.
