Improvements in Junctions for Cycle, Motor Car and other Frames.
We, ALFRED HENRY WEBSTER, of 394, Monument Road, Birmingham, in the
County of Warwick, Works Manager, and THE DIAMOND CYCLE COMPONENTS
AND ENGINEERING CO. LIMITED, of King Edward's Road, Birmingham, aforesaid,
do hereby declare the nature of our said invention to be as follows:-
Our invention has for its object improvements in junctions for cycle motor car
and other frames which are so constructed that we obtain perfectly solid and
firm junctions between the lugs and tubes and other junctions of cycle and other
framing without any brazing or heating of the parts to be joined together.
We will explain our new junction as applied to an ordinary lug of a cycle
frame; We bore the lug out so as to make a good fit between the tube and the
lug or other part to be joined together. We then prepare a double liner which
fit into each other like circular or annular cross wedges that is to say the inside
of the outer liner is bored out taper and the outside of the inner liner is
turned to a corresponding taper. The outside of the outside liner is parallel
and made to just fit the inside of the tube tightly. When the inside liner is
placed inside the outside liner it cannot be pushed entirely home by hand but
has to be driven or drawn by a screw nut or cross pin in such a manner as to
expand the outside liner sufficiently to expand the tube in the lug or other part
in which it is desired to fix it. Sometimes we slit the outer liner through one
side entirely or partly slit it or more than one slit may be used and such slit
or slits may only extend through the thick end of the outside liner leaving the thin
end not split as we prefer the outside liner to be sufficiently long for the thin
or feather edge to project beyond the end of the lug to impart a sort of spring
or break and to avoid a sudden place in the junction. If the outer liner is made
of softer metal than the inner liner and the inner liner is hard and thicker than
the outer liner sufficient expansion of the outer liner will be obtained to expand
it and the tube in the lug without splitting or slitting or at any rate with only

a limited amount of slitting at the thick end.
other junctions a cross hole is bored through the lug or socket and through each
of the liners with a taper drill so as to receive a taper pin which is passed
through the parts and having its end screwed to receive a nut. The cross hole
in the inside taper liner is so drilled as to be drawn further into the outer liner
as the taper pin is driven or drawn home. In other joints the point of the
inner liner may be screwed and thus drawn home.

Improvements in Junctions for Cycle, Motor Car and other Frames.
We, ALFRED HENRY WEBSTER, of 394, Monument Road, Birmingham, in the
County of Warwick, Works Manager, and THE DIAMOND CYCLE COMPONENTS
AND ENGINEERING CO. LIMITED, King Edward's Road, Birmingham, aforesaid,
do hereby declare the nature of our said invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement:— ·
Our invention has for its object improvements in junctions for cycle motor car
and other frames which are so constructed that we obtain perfectly solid and
firm junctions between the lugs and tubes and other junctions of cycle and other
framing without any brazing or heating of the parts to be joined together.
We will explain our new junction as applied to an ordinary lug of a cycle
frame: We bore the lug out so as to make a good fit between the tube and the
lug or other part to be joined together. We then prepare a double liner which
fit into each other like circular or annular cross wedges that is to say the inside
of the outer liner is bored out taper and the outside of the inner liner is
turned to a corresponding taper. The outside of the outside liner is parallel
and made to just fit the inside of the tube tightly. When the inside liner is
placed inside the outside liner it cannot be pushed entirely home by hand but
has to be driven or drawn by a screw nut or cross pin in such a manner as to
expand the outside liner sufficiently to expand the tube in the lug or other part
in which it is desired to fix it. Sometimes we slit the outer liner through one
side entirely or partly slit it or more than one slit may be used and such slit
or slits may only extend throug the thick end of the outside liner leaving the thin
end not split as we prefer the outside liner to be sufficiently long for the thin
or feather edge to project beyond the end of the lug to impart a sort of spring
or break and to avoid a sudden place in the junction. If the outer liner is made
of softer metal than the inner liner and the inner liner is hard and thicker than
the outer liner sufficient expansion of the outer liner will be obtained to expand
it and the tube in the lug without splitting or slitting or at any rate with only
a limited amount of slitting at the thick end. In the more ordinary cycle and
other junctions a cross hole is bored through the lug or socket and through each
of the liners with a taper drill so as to receive a taper pin which is passed
through the parts and having its end screwed to receive a nut. The cross hole
in the inside taper liner is so drilled as to be drawn further into the outer liner
as the taper pin is driven or drawn home. In other joints the point of the
inner liner may be screwed and thus drawn home.
In order that our invention may be more clearly understood and easily carried
into practical effect we have appended hereunto a double sized sheet of draw-
ings upon which we have illustrated examples of our mode of making a junction.
Figure 1 is a plan view shewing the tube T joined to the top lug of the
steering socket of a cycle according to our invention.
Figure 2 is a similar view to Figure 1 shewing a portion of the lug and tube
broken away.
Figure 3 is a sectional view of the junction as shewn at Figure 1.
Figure 4 is a side elevation of Figure 1.

Figure 9 is a similar view to Figure 4 shewing a slightly modified form of
our junction.

Figure 11 is a view of the adjusting pin as shewn at Figures 9 & 10.
Figure 12 is a plan view of the washer as shewn at Figures 9 & 10.
In carrying our invention into practice as applied to an ordinary lug of a cycle
frame, we bore the lug A out so as to make a good fit between the tube T and
the lug or other part to be joined together. We then prepare the liners B and D)
which fit into each other like circular or annular cross wedges that is to say
the inside of the outer liner B is bored out taper and the outside of the inner
liner D is turned to a corresponding taper. The outside of the outer liner B is
parallel and made to just fit the inside of the tube T tightly and the inner
liner D is made so that when it is placed inside the outer liner it cannot be
pushed entirely home by hand but has to be driven or drawn by the taper screw
or cross pin E to which taper pin in itself we make no exclusive claim The
taper holes 6 and 62 and and d are formed respectively in the liners B
and D to receive the taper pin E, and the outer liner B is preferably split at 63
as clearly shewn at Figures 2 and 5. A taper hole is also formed in the lug
and in the end of the tube. The holes in the lug tube and outer liner B may
be bored with a taper drill at one operation but the holes in the inner liner Ď
are bored separately. It will thus be seen that when these liners are placed in
position in the end of tube T and the end of the tube inserted in the lug A and
the taper pin E inserted through the holes in the long tube and liners by
tightening or drawing the taper pin inwards by the nut el it will force the inner
liner further into the outer finer on account of the holes and d² in the
inner liner not being opposite the other holes that is to say the left hand side of
the taper pin bears against the left hand sides of the holes and of the
liner and forces it into the liner B, until the holes d' and are exactly in
line with holes and 62 respectively thus expanding the outer liner and tube
and thereby firmly and rigidly securing the tube T in the socket. In some cases
the slit in the outer liner may only extend through the thick end leaving the
thin end not slit as we prefer the outer liner to be sufficiently long for the thin
end or feather edge to project beyond the end of the lug to impart a sort of
spring or break and to avoid a sudden place in the junction. Or we may form
more than one slit in the outer liner if desired. If the outer liner is made of
softer metal than the inner liner and the inner liner is hard and thicker than
the outer liner sufficient expansion of the outer liner may be obtained to expand
it and the tube in the lug without slitting or splitting or at any rate with only
a limited amount of slitting at the thick end.
At Figures 9 and 10 we have shewn a modified form of our junction. In
this case instead of a taper pin we use the eccentric pin F and eccentric washer fl
as shown at Figures 11 and 12. The holes in the lug and tube and the outer
liner B are formed larger so as to receive the collar f of the pin F and the
washer f as clearly shewn at Figure 11. It will thus be seen that by slackening
the nut and turning the pin F by means of the head in the direction of
the arrow that it would force the inner liner D out of the outer liner B thus
loosening the junction but if the pin F is turned in the opposite direction or
turned right round it will force the inner liner into the outer liner thus
expanding the outer liner and the end of the tube T in the lug thereby forming
a firm and rigid junction as clearly shewn at Figure 10. In some cases the
point of the exterior of the inner liner 1 may be screw threaded and the interior
of the outer liner B tapped with a corresponding serew thread so that by
screwing the inner liner into the outer liner it expands.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :--
