Improvements in Means for Connecting Together Framing and other
Parts of Cycles and analogous Vehicles.
I, CHARLES HARVEY, of The Swifts, Yardley, near the City of Birmingham,
Works Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to means for securing the framing and other parts of
cycles and analogous vehicles without brazing, such as connecting the tubular
members of a frame to their junctions, or for connecting other parts of cycles and
the like to one another in such a manner as to be perfectly rigid, whilst at the same
time admitting of the said parts being separated with ease when required to be
dis-assembled for transit or storage.
In carrying out my invention in connection with the securing of the members
of a frame to the junctions, each end of the said members is preferably slightly
coned and then flanged by turning the extreme edge of the metal into a bead and
then flattening the same into an annular flange which is nipped or clamped between
the opposed faces of a flange on the outward end of the lug and another flanged
part of a slightly inside-coned sleeve slipped upon the end of the said tubular
member prior to the flanging up of the extreme edge thereof.
The coning of the inside of the sleeve is a little less than the coning of the
member which said sleeve has a series of transverse holes through its flange coming
opposite like holes in the flange of the lug, and where-through screw pins, bolts
or equivalents pass in drawing the sleeve or ferrule up to the lug and clamping the
annular turned-up edge of the tube member between them, hence a rigid joint
In carrying out another form of my invention, I prepare the ends of the tube as
before, by flanging and coning (which latter operation may be performed by driving
in a slightly tapered punch) and then I slip thereon an inside shouldered ferrule
or sleeve, a part of which is inside, or both inside and outside, wormed with the
interiorly wormed part adapted to screw upon an exteriorly screwed lug, having
an inwardly directed flange or choking coming opposite the inside shoulder of the
sleeve, and between which opposed parts the flanged end of the tubular member
is clamped by the screwing of the ferrule upon the lug, by which the inside coned
part of the said ferrule is drawn up tight upon the coned end of the tube.
That end of the ferrule which takes upon the lug is longitudinally split, so as
to admit of the walls of that part of the ferrule being closed around the lug by
the screwing thereon of a ring nut having a plain taper mouth coming over a
like taper part of the sleeve, so that the screwing up of the said nut causes the
coning of the one part to travel over the coning of the other and so gather the
split parts of the ferrule securely around the lug.
Instead of employing a supplementary locking or contracting nut, I may have
opposite lugs arranged on either side of the splits in the ferrule and direct a screw

page_text: pin or pins between them by the screwing up of which the contraction of the
ferrule around the lug or equivalent part is effected and a rigid connection of the
tube end made.
If necessary the joints of the junctions may be broken by internal liners, and
instead of flanging the extremity of the tube, an annular rib or shoulder may be
formed inward of the said end, so that the part forward of the rib would form the
joint-breaking liner. This rib may be formed by making an annular bulging on
the tube by internal rolling or otherwise and then collapsing the walls of bulging
to form the annular flange.
As a further form of my invention, I make the lug conical mouthed or conical
socketted with an inwardly disposed crossing wall or bar, having a wormed hole
through its middle, wherethrough the screwed end of a bolt takes, and with the
other end of the bolt, being provided with a milled or toothed head whose shank
immediately close up to the head passes through a plain hole in a bar or diaphragm,
wall or equivalent crossing the inside of a liner, or ferrule located within the end
of the conical end or conical and flanged end of a member to be connected to the
lug. A hole is made through the wall of the tubular member opposite the milled
head, so that when the said milled head is rotated, by an instrument passed through
the hole, the whole of the parts are drawn together and a rigid joint made by the
action of the screw.
The application of my invention to the securing together other parts of cycles
and other analogous vehicles differs in no essential respect from its application
to the connection of the tube of a cycle framing to its junction lug, as herein
described.
Improvements in Means for Connecting Together Framing and other
Parts of Cycles and analogous Vehicles.
I, CHARLES HARVEY, of The Swifts, Yardley, near the City of Birmingham,
Works Manager, 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 means for securing together the parts of the framings
of cycles and analogous vehicles without brazing, such as for connecting the tubular
members of a frame to their junctions, or for connecting other parts of cycles and
the like to one another in such a manner as to be perfectly rigid, whilst at the same
time admitting of the said parts being separated with ease when required to be
dis-assembled for transit or storage.
Figure 1 of the accompanying drawings represents a longitudinal vertical section
of a mechanical or brazeless joint constructed according to one form of my inven-
tion and shown as applied to the connection of a tubular member of a cycle framing
to one of the junction lugs thereof.
Figure 2 is a section of Figure 1, upon the dotted line, x.
Figure 3 represents the parts of the said joint separated.
Figure 4 is a front elevation of the abutment collar which surrounds the tube,
separately.
According to this form of my invention, each tubular member a, to be connected

page_text: up, has upon it, near its end, an annular flange, beading or collar a¹, adapted, after
the end a, has been placed into the socket 6, of a junction lug such as b, to abut
against the face of a shoulder or flange 62, formed circumferentially around the
mouth of the said socket, and is there nipped or clamped between the face of the
said shoulder and the opposed face of a loose flange or sleeve c¹, which may, for
convenience of connection, be made in sections as shown in Figure 4 and which
surrounds the tube, outwards of the said collar beading a¹, the said opposed
flanges b, c, being drawn together by means of a series of screw pins d, passing
through preferably plain eyes c³, of the one and taking into coincident wormed
holes 63, in the other, or the holes in both parts may be plain' and the screwed ends
of the pins may protrude and receive nuts, by the screwing up of which, the
clamping of the said flanges against the annular beading of the rim may be
effected.
I
To prevent the socketted parts turning or twisting one over or within the other,
may form a feather or rib such as 6, on the inside of the socket of the lug adapted
to take into a longitudinal key-way a", made along the tube, or the feather may
be formed on the tube and the key way in the socket, or any other well known
means may be employed for preventing the members twisting relatively to one
another.
The annular beading or abutment on the tube may be made by first forming an
outward bulging around the tube, which is then collapsed or closed up end-wise
forming the beading a¹, as shown in Figure 1, or an annular inward indenta-
tion a (see Figure 5) may be provided in the tube at a suitable distance from the
end, and into which, a split or other metal ring a³, is sprung, shrunk or otherwise
secured to form the necessary flanging.
If required, and in order to give a more perfect fit and a more rigid joint, the
socketting parts may be he and she coned.
Figure 6 is an elevation of another form of mechanical joint, in accordance with
my invention, and shown as applied to cycle-frame construction.
Figure 7 is a longitudinal vertical section of the said joint.
Figure 8 is a cross section of Figure 7 upon the dotted line r¹.
Figure 9 is a cross section of the same view upon the dotted line r².
Figure 10 is a longitudinal vertical section of
junction lug separate.
Figure 11 is a longitudinal section of the tube to be connected to the said
lock.
Figure 12 is a cross section thereof upon the dotted line 23.
Figures 13 and 14 represent separate elevations (with a part of the latter in
section) of the inside screwed ferrule and outside screwed ring or nut, by which
the attachment or locking of the tube to the lug is effected, after the one has been
socketted within the other.
Thus, in this arrangement, the tubular member a, which is to be joined to the
lug b, is formed or provided with an integral or attached flange or beading a²,
disposed a distance inwards of the extreme end, and being of a diameter suitable
for taking within, and abutting against the shouldered inner end 2, of an inside
screw mouth or enlargement 6, at the end of the socket 3, into which the end of
the tube is introduced and then secured or locked by screwing into the said mouth,
the locking ring c, the inner end c¹, of which abuts against the outer side of the
beading or flange a², which is thus clamped between it and the shoulder 62, of the
socket, and then the whole joint is enclosed or boxed in by means of an inside-
screwed locking ferrule d, which is wormed upon the outside threaded end b', of
the lug.
The rotation of the parts is prevented by a feather and key-way arrangement
such as a5, 65, or the like, and the outer ends of the ring nut and ferrule may be
notched or gapped at 2, 2, to facilitate the screwing and unscrewing of the same
by means of a forked or other tool; whilst as a modification the end of the socket
may be he-coned and longitudinally split at parts, with the splits closed around
or onto the locking ring by means of a she-coned ferrule so that on the coning of

page_text: the one part being travelled over the coning of the other, the ferrule is securely
locked to the nut. As a still further modification, the ferrule or enclosing cap,
instead of screwing onto the outside of the junction socket, may screw onto a
wormed extension or tail end of the locking ring.
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
First In a mechanical detachable joint for parts of cycle and analogous
framings, forming or providing near or inwards of the end of the tubular member
to be connected, a flanged collar or beading, and securing the tubular member to
its junction fitting by clamping the said collar between a flange or lags upon the
said junction and a loose collar, ring or the like, with the part of the tube outwards
of the collar extending into the lug with or without a key, or rib on the one part
taking into a groove in the other part, substantially as and for the purpose described
and set forth in Figures 1 to 5.
Secondly: In a mechanical-detachable joint for parts of cycle and analogous
framings, forming or providing near or at the end of the tubular member to be
connected, a flange, collar, beading or equivalent, and securing the tubular member
to its junction fitting by clamping the collar thereof between an internal shoulder
of the junction socket and an outside screw ring or nut, which is slipped onto
the tube and wormed into the screwed mouth of the said socket with or without
a locking ferrule, such as d, substantially as described and set forth in Figures 6
to 14.
