Improvements in the Mode and Means for Making the Junctions of
Cycles, Motor Car and other Frames, Bedstead and Fender Junc-
tions, and other purposes so as to avoid Brazing.
I, EDWIN TAYLOR, of Pemberton 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 cycles motor car and other frames, bedstead and fender junctions
and other purposes so as to avoid brazing.
In order that my invention may be clearly understood and more easily carried
into practical effect have appended hereunto drawings illustrating examples of
the application of my invention to several junctions and articles which will be
sufficient to enable others to apply the principle more widely to the various circum-
stances met with in practice. The junction pieces and tubes may be of other
sections instead of round.
Figure 1 is a cross socket junction piece S with the tubes T applied and united
thereto according to my invention.
Figure 2 is a similar view to Figure 1 shewing a different form of junction.
Figure 3 is another example of a tube T joined to the socket S.
Figure 4 is a part sectional view of Figure 3.
Figure 5 is a similar view to Figure 3, shewing a further modification of my
junction.
Figure 6 is an end view of another modification shewing the grooves extending
around a portion only of the tube and socket.
Figure is a perspective view of the ferrule used in connection with the junction
as shewn at Figure 6.
Figure 8 is an end view of a tube and socket shewing one method of drawing
the wire W into the groove.
Figure 9 is a sectional view shewing two lengths of tubing joined together.

Figure 11 is a cross sectional view of Figure 10 taken on the line -y.
Figure 12 is a part sectional view of another example of my tool.
Figure 13 is a
plan view of the tool as shewn at Figure 12.
Figure 14 shews a further modification of my tool.
Figure 15 is a view shewing a flexible headed tool.
Figure 16 is a view shewing the inner face of some of the links as shewn at
Figure 15.
Fig. 17 shews a further modification of my tool with the exterior hexagon.
In carrying my invention into practice I turn or form in the interior of the
socket S the recessed part or parts that is one two or more of such recesses. The
end of the tube T is also recessed with one or more corresponding recesses which
when the tube is of a thin gauge is or are made by pressing portions of the tube
077

page_text: inwards as shewn so as to retain the full thickness or nearly the full thickness of
the tube at the recessed parts. I then put into one of the recesses in the tube T
a ring of fusible metal such as a¹ which is of suitable thickness to fill up the recess
without projecting and if necessary the ends of this ring may be connected together.
I also place in the corresponding recess in the socket a ring such as a¹. Or these
rings instead of being loose in the tube and socket may be fixed. Or the ring
or rings may be formed without a joint and either cast into the grooves or forced
in by pressure. When this is done the tube T is placed into the socket S until
the ridge which is formed on the tube butts against the end of the socket thus
indicating that all the rings are opposite one another as indicated in Figures 1, 2
and 4. I then force the wires W which may be round as shewn at Figures 1, 3
and 4 or flat as shewn at Figure 2 into the two remaining grooves through the
holes which are made in the socket for that purpose. These wires may be drawn
in to the grooves by threading one end into the hole s² and in to a hole in the tube
and then by turning or twisting the tube in its socket the wires are gradually
drawn around the grooves and afterwards cut off flush with the outer surface of
the socket. Or the wires may be cut into short lengths and headed at one end
and then threaded through the holes in the socket and tube into the interior of
the tube as shewn at Figure 8 when by twisting or turning the socket or tube
the wire will be drawn into the grooves, the hole in the socket being countersunk
so as to allow the headed end of the wire to be flush with the outer surface of the
socket. The junctions are then placed in a stove or the like & subjected to a
temperature sufficiently high to fuse the metal rings. In some cases the grooves
in the socket may be formed by bulging them outwardly as shewn at Figures 34
and 5 and in the case as shewn at Figure 5 I form these grooves spirally the wire
being drawn or forced around this spiral and the fusible metal rings inserted in
the plain groove.
At Figures 6 and 7 I have shewn a further modification of my
junction. In this case in addition to the grooves for the fusible rings of which
there may be two or more I form the grooves or recesses t³ in the tube and socket
only extending a portion of their circumference as shewn at Figure 6 and into
these grooves I force the tongues f¹ which are cut out of the ferrule or ring F as
shewn at Figure 7. It will be easily understood that when this ferrule is placed
around the socket and the ends of the tongues inserted into the holes st that by
turning the ferrule by means of a key the tongues will be forced into the grooves.
In some cases the fusible rings a¹ and the wires W may be formed as shewn at
Figure which represents two pieces of tubing joined together. In all cases
only one of the grooves or recesses may have a wire inserted and the other two
grooves the fusible rings or wires may be used entirely, and the ends of the tube
may be flanged over inwardly for strengthening purposes or thickened ended
tubes may be used. Although I prefer the fusing point of the fusible rings not
to exceed 900 Fah. I may in some cases use a metal of a harder substance that
would require a greater heat to fuse.
.At Figures 10 to 17 I have shewn various tools for forcing the wires W into
the grooves or recesses in the socket and tube when forming my joint. In the
method as shewn at Figures 10 and 11 I hinge the arms B and B together at 62
so as to form the head circular to fit around the socket, and in this head I form
the groove 63 into which the wire is placed, one end being left free so as to easily
enter the hole in the socket when by turning the tool round the wire is gradually
forced into the grooves or recesses. The handles or shafts of this tool may be
of any desired length and may be bent or cranked to suit various purposes. The
screw D is provided for holding the jaws firmly together while the wire is forced
into the grooves or recesses. The tool as shewn at Figure 14 is very similar to
that shewn at Figure 10 only the jaws are hinged together at the opposite ends.
At Figures 12 and 13 I have shewn another modification of my tool. In this case
I form the jaws at right angles to the shafts and the shaft E which fits on to
the shaft E is reduced at its end and formed with the projection which fits
into groove h¹ formed in the bush H. The end of the shaft E¹ is screw threaded

page_text: and on to the end of this shaft the bush H is secured and by turning this bush the
jaws are opened and closed. I have shewn two grooves in these jaws for inserting
two pieces of wire which can be forced into the recesses or grooves in the socket
and tube simultaneously when forming the junction, but there may only be one
of these grooves in the jaws of the tool or more than two. The pin which works
in the slot e formed in the shaft E' is for the purpose of keeping the shafts in
position.
At Figures 15 and 16 I have shewn an example of a flexible head tool which
consists of the links J on the inner faces of which I form a groove for the reception
of the wire. The link j¹ nearest to the shaft or handle of this tool is formed as
shewn at Figure 16 so as to allow the other end link to pass through and this end
may be secured in any desired manner.
In the method as shewn at Figure 17 I form the exterior of the jaws hexagon
or like shape so that the jaws can be operated by a wrench or spanner, thus
dispensing with the shafts or the jaws may be round on the exterior and provided
with a hole for the reception of a peg formed in the interior of the spanner or
wrench.
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:-
CLAIMS.
First: Making cycle and other junctions by forming grooves in the tube or
other member and also in the socket or lug with a fusible key or keys a steel or
other solid key or keys combined and put together substantially in the manner
herein set forth and shewn upon the drawings.
Second-The improvements in the mode and means for making the junctions
of tubes with their sockets characterised by forming two or more grooves or
recesses in the end of the tube and in the interior of the socket and inserting in
one or more of the grooves in the tube and in the corresponding groove or grooves
in the socket a ring of fusible metal the tube being afterwards put into the socket and
a wire either drawn or forced through a hole in the outside of the socket so as to
fill up the remaining groove or grooves the junction being then subjected to a
temperature sufficiently high to fuse the metal rings in the manner and for the
purpose substantially as herein set forth and as shewn.
'
Third-In junctions for cycles and other frames forming spiral or other grooves
or recesses in the socket with a strengthening external bulge whether straight
or spiral in the manner and for the purpose substantially as herein set forth and
as shewn at Figures 34 and 5.
Fourth In junctions which form the subject of the first claim, the hand tool,
the jaws of which are formed with a recess for holding the wire so as to force it
into or around the grooves or spaces in the manner substantially as herein set
