Improvements for Making Cycle and other Frame Joints without
Brazing.
We, WILLIAM RADFORD, of Stoke Green, Coventry, Cycle Works Manager,
and WILLIAM SMITH, of 17, The Butts, Coventry, in the County of Warwickshire,
Mechanical Engineer and Draughtsman, do hereby declare the nature of this
invention to be as follows:-
This invention consists in constructing and arranging and working in the
manner hereinafter described. The tube expanders for making joints or connec-
tions in cycles or other tubular frames, or tubes without brazing. I will describe
my invention for expanding a tube by the means of two half disc's or less, than
half disc's, such disc parts have a groove across their diameter or inner sides.
There is also a bolt or screw with a round or other shaped head. There could
also be used a sphere, ball, and an ordinary set screw or bolt. The action of the
parts are as follows:-I will describe same by using a bolt or screw with a round
or other shaped head. Take the bolt and place its head at the one end of the grooves
in the part disc's, and the other end of bolt at the other end of the part disc's
thus the bolt is now between the part disc's and the head being
or
or screwed end of bolt
larger than
screw, this causes
the grooves or the inner sides of the part disc's to be in an angular position
in regards to the longitudinal centre of the bolt or screw, by now placing the parts
before mentioned in the end of tube such tube having cuts or slits in it longitu-
dinally, also two holes in it, lineable with each other across its diameter, also the
socket or sleeve to have similar holes, and by placing the tube into the socket or
sleeve with holes and centre of bolt or screw all lineable with each other, now
through the holes drive the bolt head to-wards the centre of the tube and the other
end of bolt or screw will come through the side of socket or sleeve, place on
the bolt or screw a nut or nuts to lock or fix bolt in position.
the shank
If a sphere or ball was being used, you would then force it to-wards the centre
by means of a set screw or other ordinary means which are well known. The
before mentioned half disc's could be a disc all in one piece but partly slit or
cut through.

We, WILLIAM RADFORD, of Stoke Green, Coventry, Cycle Works Manager,
and WILLIAM SMITH, of 17, The Butts, Coventry, in the County of Warwickshire,
Mechanical Engineer and Draughtsman, 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:
-
For improvements for making cycle and other frames without brazing to be
as follows: Our invention consists in constructing and arranging and working
in the manner herein after described.
The tube expanders for making joints or connections in cycle and other tubular
frames without brazing. We will describe, our invention for internal expansion
of a tube by the means of two half disc's or less than half disc's, such disc parts
have a groove across their diameter or inner sides, there is also a bolt with a round
or other shaped head. There could also be used a sphere, ball, or an ordinary
set screw or bolt. The action of the parts are as follows:-We will describe same
by using a bolt with a round or other shaped head.
Take the bolt and place its head at the, one end of the groove, in the part discs
and the other end of bolt at the other end of the part discs, thus the bolt is now
between the part disc's, and the head being larger than, the shank or screwed end
of bolt this causes the grooves on the inner side of the part disc's to be in an
angular position, in regards to the longitudinal centre of the bolt, by now
placing the parts before mentioned in the end of the tube such tube. having cuts,
or slits, or serrated longitudinally, also two holes in it lineable with each other
across its diameter, also the socket or sleeve. to. have similar holes, and by placing
the tube into the socket or sleeve, with holes and centre..of, bolt all lineable with
each other, now through the holes drive the bolt head towards the centre of the
tube, and the other end of bolt will come through the other side of socket or sleeve,
place on the bolt a nut or nuts to lock, fix, or. bolt. part disc's in position. If a
sphere or ball was being used, you would then force it towards the centre by means
of a set screw or other ordinary means which are well known. The part disc's
could be placed inside a short piece of tube or bush having slit, cut, or serrated
end, which could be placed inside the frame tube (or other tube) by this means
the cycle tube (or other tube) would. be held fast or compressed between socket
or sleeve, on the outside.. And the short tube or bush on the inside.
In the accompanying drawings Eigure 1 represents a longitudinal section,
Figure 2 represents a transverse section on line L, M. Figure 3 represents the
two part discs with parallel grooves P, P, between them. A, A, are the part disc's,
P are the grooves in part disc's, Bis the head of bolt for forcing part disc's A, A,
apart. C is the shank of bolt, D, is the nut on the bolt B, C, for bolting the part
discs apart, K, K, are the slits, cuts or parts that could be serrated in tube.
Figure 4 represents a longitudinal section, Figure 5 represents a transverse section,
on line N, O. Figure 6 represents the two part disc's E, E, with parallel surfaces
between them. Also a spring J, for keeping them apart when placed in tube,
E, E are the part disc's G. is the head of bolt for forcing part disc's E, E, apart
H, is the shank of bolt, F, is the nut on the bolt G, H, for bolting the part disc's
apart, K, K are the slits, cuts, or parts that could be serrated in tube. The action
of the parts are as follows, for Figures 4, 5 and 6. We will describe same by using
a bolt, with a round or other shaped head, take a tube, such tube having cuts,

page_text: slits, or serrated longitudinally, also two holes in it lineable with each other across
its diameter, by now placing part disc's E, E, and spring J, by compressing them
together to place in such tube, with their parallel surfaces lineable with the holes
across diameter of tube, now place end of tube into the end of socket or sleeve,
which has similar hole in each side lineable across its diameter, and by placing
the holes in tube lineable with holes in socket or sleeve, then put the bolt G, H,
through the lineable holes in socket and tube, and between the parallel surfaces
of the two part disc's E, E, until the bolt end H, comes through the opposite side
of socket or sleeve, now screw the nut F, on the bolt end H, and by so doing it
will pull the head G of bolt nearer to the centre of tube, thus forcing part
disc's E, E apart, the parallel surfaces of same being in an angular position owing
to the head G being larger than the end H, of the bolt G, H, it will now be seen
that the part disc's are locked, fixed or bolted in position.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we would have it understood
that we are aware of the Specifications of Henry Belcher, Frederick Easom and
Frederick Westwood Nos. 24564 and 25,025, A.D. 1896, and that we do not claim
anything described or claimed therein but we declare that what we claim is:-
1st The improvements for making cycle and other frame joints without braz-
ing, constructed substantially as herein described, and illustrated by Figures 1,
2, 3, 4, 5 and 6 of the accompanying drawing.
2nd The two half disc's or less than half disc's, with parallel surfaces or grooves
across their diameter or inner sides, to be driven or forced apart by means of
a bolt with a round or other shaped head, or a sphere, ball, or an ordinary set screw
or bolt, substantially as herein described and illustrated by Figures 1, 2, 3, 4, 5
and 6, of the accompanying drawing.
3rd The two half disc's or less than half disc's with parallel surfaces or grooves
across their diameter or inner sides, to be driven or forced apart by means of
a bolt with a round or other shaped head, or a sphere, ball, or an ordinary set screw
or bolt, substantially as herein described and illustrated by Figures 1, 2, 3, 45
and 6 of the accompanying drawings such parts placed into a short piece of tube
or bush partly slit, cut, or serrated, such short tube or bush placed within a tube,
and such tube to be expanded in a socket or sleeve by such means as herein
described.
