Improvements in Making Connecting Joints for Metallic Cycle
Frames and other suitable purposes.
JOHN WHITEHEAD 42 Anglesey Street Lozells, Birmingham, in the County of
Warwick, Art Metal Worker, do hereby declare the nature of this invention to
be as follows:--
And I proceed to carry the same into effect as hereinafter described, the Parts
known in the Cycle Trade as the Lugs really being the various joints, which hold
the Frame of a cycle together, in these Lugs, the holes are usually bored parallel,
ready to receive the ends of the Tubes which form the Frame of a cycle ready for
Brazing, but instead of Parallel, I bore the holes, so as to be tapered outwards,
that is to say, the hole in the Lug will be wider at the bottom or extreme end, than
at the entrance."
I next prepare the Tube by sawing, slitting, or otherwise making a number of
slots or slits, longitudinally in the end of Tube which is to enter the hole in the
Lug, but previous to putting the Tube into the Lug, I place in the slotted end
a wood or metallic' wedge, of round, oval, or other suitable shape, so that when
the Tube is put into the Lug, the wedge can be forced or hammered into the
Tube when each of the slotted sections, will be forced outwards, and flush against
the wide and inner sides of the Lug, thus wedging it firmly, and to afford greater
strength I may leave the wedge in the Tube.
This Invention is intended to take the place of Brazing, for making joints for
Cycle Frames, Motor Car Frames, or for any other class of Metallic Joints, for
which the Invention is applicable.
The advantages claimed are that it makes a safer and more secure joint, and
less costly, for it is well known, that Brazed Joints, frequently break, or become
loose, by constant viabration, and other causes.
In some instances, instead of leaving the wedge in the end of Tube, as before
mentioned I may simply expand the extreme ends of the steel or other Metallic
Tubes, into recesses of, suitable shape, which I may form, on the inner sides of the
Lug, or the inner sides of the Lug may be made: with wider bore as before
mentioned, either oval or round, or other suitable shape, the Tube ends, I should
expand when placed in the Lug, by means of a screw pressure arrangement,
hammering, or other force or pressure, that may be most suitable for the purposes
that it may be required.
So long as it will suitably force a wedge, and expand the Tubes in the Lug,
having wider or expanding bore, recesses, or other like arrangements, so as to
dispense with the aid of Brazing for the purpose of making Metallic Joints, for
various purposes..

I JOHN WHITEHEAD of 42 Anglesea Street Lozells Birmingham Art Metal
Worker 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:-
I proceed to carry the same into effect as hereinafter described the parts known
in the cycle trade as the lugs really being various joints which hold the frame
together, in these lugs the holes are usually bored parallel ready to receive the
ends of the tubes which form the frame of a cycle ready for brazing but instead
of parallel I bore the holes so as to be tapered outwards that is to say the hole in
the lug will be wider at the bottom or extreme end than at the entrance.
I next prepare the tube by sawing slitting or otherwise making a number of
slots or slits fongitudinally in the ends of tube which is to enter the holes in the
lug. I place in the slotted ends a metallic wedge of round, oval, or other suitable
shape so that when the tube is put into the lug, the wedge can be forced or
hammered into the tube when each of the slotted sections will be forced outwards
and flush against the wide and inner sides of the lug, thus wedging it firmly,
and to afford greater strength I may leave the wedge in the tube. In some
instances instead of leaving the wedge in the end of the tubes as before mentioned
I may simply expand the extreme ends of the tube into the lug having a suitable
hole or bore, the inner sides may be made with wider bore as before mentioned
either round, oval, or other suitable shape or formation; the tube ends I should
expand when in the lug by means of a screw pressure arrangement, hammering,
or other force or pressure that may be most suitable for the purposes that may be
required.
To prevent the tubes from rotating I form the lug with a stud or key projection
fitting between one of the slots in the tube, I may also additionally secure the
parts by rivets or pins, or I may coat them with tin or solder which would sweat
the parts together at a low heat so long as such parts are wedged together in the
manner before mentioned,
I will now proceed to describe the accompanying drawings:-
Figure 1 partly in section shews all the parts fitted together, a is the tube of
frame 6 is the lug, c is the wedge.
Fig. 2 is a representation in perspective of the wedge c.
Fig. 3 shews the connected parts in section a is the tube 6 is the lug, c the
wedge and d the stud or key projection.
Fig. 4 shews method of fixing "ball head tube" or "seat pillar tube" by
forcing a portion of the one tube into the end of the other. a is the frame
tube is the lug, c the wedge and the portion of "ball head" or "seat pillar
tube" forced into the interior of wedge c.
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:-
First. Making lugs or joints with a tapered bore enlarged at extreme inner
end to receive round oval or any suitably shaped tube.
2nd. The use of tubular of solid wedges
of such tubes inside the said lugs or joints.
or their equivalents for expanding ends

page_text: 3rd. Leaving wedges or their equivalents inside the tubes after expansion for
strengthening purposes.
4th. Slitting the ends of tubes to facilitate expansion.
5th. Forming the lugs with interior studs or key projections, and the tubes with
slots fitting over same to prevent rotation.
6th. Fixing the "ball head" and "seat pillar" tubes forcing them into mouth
of wedge.
