Improvements in the Construction of Mechanical Joints for the
Tubular Frames of Velocipedes and other Vehicles.
I, OSBORN COLLINS, of Poole, in the County of Dorset, Cycle Manufacturer, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to improved constructions of mechanical joints for the
tubular frames of velocipedes and other vehicles, the objects being to produce
mechanical joints which shall not shake loose or be affected by vibration and to
entirely dispense with brazing and so prevent the possibility of burning or injuring
the tubes.
My invention comprises essentially joints made by rivetting the tubular members
together either directly to each other, by forming laps or flanges on one or both
of the meeting edges of the tubular members or indirectly by using a ferrule or liner
either inside or outside the said members and rivetting the meeting edges thereof to
the said ferrule or liner. When ferrules or liners are used I prefer to make one or
both their edges of a serrated or zig-zagged form and employ a double row of
rivets for each end of the tube. By the employment of an inside ferrule or liner
very neat and strong butt or flush joints may be made.
If desired a combination of the methods above described may be used in one joint;
for instance when it is desired to joint one tubular member to another member at
or about right angles with each other, a suitably shaped inside ferrule or liner is
used as well as a lap or flange formed on one end of one of the members, so arranged
that the edges of the other member will be clamped between the lap or flange and
the inside ferrule or liner.

I, OSBORN COLLINS, of Poole, in the County of Dorset, Cycle Manufacturer, 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 improved constructions of mechanical joints for the
tubular frames of velocipedes and other vehicles, the objects being to produce

entirely dispense with brazing and so prevent the possibility of burning or injuring
the tubes.
My invention comprises essentially joints made by rivetting the tubular members
together either directly or indirectly.
In the accompanying drawing which illustrates some methods of carrying my
invention into effect:.
Figure 1 is a broken view-partly in section-of two tubular members jointed
together according to this invention, and
Figures 2, 3 and 4 are similar views showing modified forms of joints.
Throughout the views similar parts are marked with like letters of reference.
Referring to Figure 1 of the accompanying drawings, the two tubular members
A and B to be joined together are provided with laps or flanges a and b so shaped
and arranged that they overlap one another and are rivetted together by rivets c
etc. arranged in one or more rows.
Referring to Figure 2. Only one of the members need be flanged, say the
member A, the flange a of the said member being adapted to fit over the plain end
of the other member B. The rigidity of this form of joint may be increased by
the use of a liner or ferrule C, preferably made in two halves and having a flange c
at one end, whereby it is rivetted to the member A and having serrations c¹ cut or
formed in its other end which is rivetted to the member B as shown.
Figures 3 and 4 show further modifications, the former in which the end of the
member B is shaped to butt against the member A, and the liner or ferrule C-
preferably formed as above described is placed exterior to the member B and is
rivetted to each member respectively. In the modification shown in Figure 4, the
liner or ferrule C is placed inside the member B and its flange lies within the
member A which gives a neat and strong butt or flush joint on the outside.
In some cases, to prevent the possibility of the ingress of wet or moisture and to
fill up any slight irregularity in the meeting edges of the members or liners,
I may sweat or soft solder the joints together either before or after rivetting.
It will be understood that this method of jointing is applicable, with slight
variation as to the shape or angle of the laps or flanges, to all joints required in the
construction of tubular frames of velocipedes and other vehicles.
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:--
(1) A joint for tubular frames of velocipedes and other vehicles formed by
rivetting the tubular members together either directly to each other by forming
laps or flanges on one or both of the meeting edges of the said members, or
indirectly through the medium of a ferrule or liner placed either outside or
inside the said members, as set forth.
(2) The combination with a rivetted joint for the tubular frames of velocipedes,
of ferrules or liners such as C, as and for the purpose set forth.
(3) A joint for jointing tubular members of a frame for velocipedes and other
vehicles to each other substantially as hereinbefore described and illustrated by
Figures 1 or 2 or 3 or 4 of the accompanying drawing.
