Improvements in Machinery or Appliances to be used in Uniting
Tubular Members to the Junction Lugs or Sockets of Cycle and
analogous Framings, and Lengths of Tubing to one another.
I, CHARLES HARVEY, of "The Swifts," South Yardley, near the City of Birming-
ham, Works Manager, do hereby declare the nature of this invention to be as
follows:-
This invention relates to machinery or appliances to be used in uniting or con-
necting tubular members to the junction lugs or sockets of cycle and analogous
framings, and also for uniting lengths of tubing to one another by that method in
which the union is made by a process of creasing or indenting inwards at points
the walls of the telescoping parts, by which inward bulging or displacement of
the metal the tubular lengths are united or locked to the frame junction lugs or
sockets; or to one another without soldering or brazing and subsequent dressing
of the joint or connection so made, such joints thus being of that type described
in the Specification of Letters Patent No. 24013 of 1896.
The object of the present invention is to provide efficient means for simply and
expeditiously effecting the bulging or creasing operation.
In carrying out one form of my invention in connection with joints effected!
by separated annular or part annular creasings, I employ a frame or carrier in
which the members or framing of a bicycle or the like to be operated upon are
held and there clamped, if necessary, and in conjunction with this carrier-frame
I mount a pair of jaws, one of which is fixed and the other movable, with the
operating parts fitted or provided with half or sectional creasing or rolling dies.
The movable jaw is in the form of a lever, jointed to a turning upon a pin or
journal and having preferably at its journalled end, a hell-cranked arm or lever,
suitably connected by an adjustable link or by opposite slotted and adjustable links
to a branched or bifurcated frame adapted to hold up the loose jaw and being
jointedly mounted rearwards of the fixed jaw to a rocking or part-rotating slide,
to which the said movable jaw is jointedly connected. This slide, whose outer
radius is struck from the centre or horizontal axis of the dies, works upon or
within the inner periphery of a crescent-shaped or partly-circular bed supported

page_text: or
a
by feet or by a base plate and arranged either to run upon anti-friction rollers
or spheres, or within plane guides or grooves. The rocking slide is coupled to the
inner end of a connecting rod, whose outer end is jointed to a suitably driven crank,
disc-wheel, excentric, or equivalent means for transmitting reciprocating motion
converting rotary motion into reciprocating motion for giving
backward and forward rocking movement to the slide. The movable
jaw may be operated or taking up to or away from the fixed jaw by a screw or
swivelly connected screw having a hand wheel at its outer end passing through a
screw box carried by the fore end of the bifurcated frame, and with the end of
its screw impinging against a block or extension of the said movable jaw, which
is made to approach the fixed jaw by the rotation of the screw in one direction.
Assuming that the die space between the jaws is open, the telescoped members
or parts to be annularly indented or circularly and inwardly bulged at points, are
introduced laterally into the machine and placed between the opposed faces of the
dies, which are then closed around the same by feeding the movable jaw forward
by the gradual rotation of the screw, and at the same time and whilst the members
or parts are held stationary, the jaws and dies carried by the rocking rest are then
rocked backwards and forwards so that the impressing parts of the dies make
partial or complete rotations around the said parts. Meanwhile the halves of the
dies are gradually made to approach closer and closer to one another and the metal
is gradually bulged inwards to form the necessary annular sinkings or part sink-
ings to form the joint. After this operation has been performed, whereby a number
of creasings are made at the same time, the rocking motion is discontinued and the
screw is run back when the bifurcated frame falls and allows the movable jaw to
open, whereon the article or parts operated upon may be removed.
Instead of one fixed and one movable jaw, I may employ two movable and open-
ing jaws, both of them being operated through a single screw or other equivalent
expedient which draws both the jaws together and brings the dies upon the
tubular articles under operation. Or instead of a screw, the movable jaw or jaws
may be opened or opened and closed by toggle or knee joints, such opening or
gradual closing of the jaws may be performed automatically by the motion of the
lever or link actuated from a main driving shaft or rod or other part, which gives
to a pawl wiping over a ratchet-wheel, a rocking or intermittent or continuous feed
movement as the creasing or inward bulging proceeds.
The creasing parts of the dies may be in form of journalled rollers.
As an alternative, the frame carrying the work or tubes under operation may
have a parttial rotation given to it, whilst the jaws and other parts may remain
stationary so far as rotary motion is concerned. And instead of one or both the
jaws or half dies swinging from a pivot and opening angularly they may be
arranged to work upon a horizontal or straight bed, the outer framing or guides
for the rocking rest being provided with a suitable gap or gaps to admit of the
lateral introduction of the work.
Or the creasing or inward bulging may be performed by an endless band or
rollers or equivalents, having within the space comprehended or enclosed by them
a movable and a fixed guide, one of which is formed with a rest or seating to receive
the tubular parts to be creased, whilst the other of them has an axis carrying a
sprocket wheel whose teeth gear into the spaces between the rollers and by means
of which the said band is run or traversed. Adjustment of the band is effected
by means of right and left handed screws running respectively into the fixed and
movable block, which screw is rotated as the inward bulging proceeds, the work
being at the same time continuously rotated.

Improvements in Machinery or Appliances to be used in Uniting
Tubular Members to the Junction Lugs or Sockets of Cycle and
analogous Framings, and Lengths of Tubing to one another.
I, CHARLES HARVEY, of "The Swifts," South Yardley, near the City of Birming-
ham, 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:―
4
This invention relates to machinery or appliances to be used in uniting or con-
necting tubular members to the junction lugs or sockets of cycle and analogous
framings, and also for uniting lengths of tubing to one another, by that method
wherein the union is made by a process of creasing or indenting inwards at points
the walls of the telescoping parts, by which inward bulging or displacement of
the metal the tubular lengths are united or locked to the frame junction lugs or
sockets, or to one another without soldering or brazing, (subsequent dressing of the
joint or connection so made being therefore unnecessary), such joints thus being
of the type described in the Specification of Letters Patent No. 24013 of 1896.
The object of the present invention is to provide efficient means for simply and
expeditiously effecting the bulging or creasing operation.
In carrying out one form of my invention in connection with joints effected by
forming separated annular or part annular creasings in the telescoping parts to be
united, I employ an adjustable table, frame or carrier in which the members or
the framing of a bicycle or the like to be operated upon are held and there clamped,
if necessary, and in conjunction with this carrier-frame I mount a pair of jaws,
one of which is fixed and the other movable, with the operating parts fitted or
provided with half or sectional creasing or rolling dies or tools. The movable jaw
may be in the form of a lever, jointed to or turning upon a pin or journal, so as to
be capable of opening and closing and rotating and being suitably connected to a
rocking or part-carrier or slide. This carrier slide, whose outer radius is struck
from the centre or horizontal axis of the dies, works upon or within the inner
periphery of a crescent-shaped or partly-circular bed supported on the framing of
the machine and arranged either to run unon anti-friction rollers or spheres. or
within plain guides or grooves. The rocking slide is coupled to the inner end of
a connecting rod, whose outer end is jointed to a suitably driven crank, disc-wheel,
excentric, or equivalent means for transmitting reciprocating motion or converting
rotary motion into reciprocating motion for giving a backward and forward rock-
ing movement to the slide. The movable jaw may be operated or taken up to or
away from the fixed jaw by a screw or swivelly connected screw having a hand
wheel at its outer end passing through a screw box carried by the end of the
movable jaw or tool holder and with the end of its screw impinging against a block
or extension of the fixed jaw, which the movable jaw is made to approach by the
rotation of the screw in one direction.
.
Assuming that the die space between the jaws is open, the telescoped members
or parts to be united are introduced into the machine and placed between the opposed
faces of the dies or creasing tools which are then closed around the same and then,
whilst the members or parts are held stationary; the jaws and dies carried by the
rocking carrier are rocked backwards and forwards so that the impressing parts
of the dies make partial or complete rotations around the said parts, the halves of
5 the dies being meanwhile gradually made to approach closer and closer to one
another so that the metal is gradually bulged inwards to form the necessary annular
sinkings or part sinkings to make the joint,

page_text: Figure 1 of the accompanying drawings represents a side elevation of a machine
for forming brazeless joints between tubular members by creasing or inward
annular bulgings, constructed according to one form of my invention.

member of a frame being made in placed. Figure 8 is an end view of Figure 7.
In these figures, the steady-covers or jointed lids at the opposite ends of the rest
are shown closed down, whilst in Figures 9 and 10, which represents like views
as Figures 7 and 8, the said lids or covers are shown thrown back, so as to admit
of the introduction of the tubular member into the longitudinal trough-like top-
side of the rest.

means employed for retaining the rolling and acting contacts in position and
securing the die-plates to the jaws of the levers.
The same letters of reference indicate corresponding parts in the said Figures 1
to 19 of the drawings.
a is the main bed or framing of the machine, which is slotted or has a longitu-
dinal clearance a¹, extending from end to end, or nearly so, and is suitably sup-
ported upon standards or feet a². Mounted in bearings a³, at the right hand end
of the frame is a transverse shaft at, carrying fast and loose band pulleys a³, ab,
and a toothed pinion a', which gears with a larger toothed wheel b, suitably

page_text: mounted in a bearing such as 6', and having on the face of it, a slotted crank arm b²,
to which one end c¹, of a connecting rod c, is adjustably connected, whilst the other
end, of the said rod is similarly attached to a slotted extension or rib d', of a
sliding block d, to which a reciprocating movement is given on the rotation of
the driving wheel b. The said slide is guided in its longitudinal traverse by suit-
able guide-plates, bolted or otherwise attached to the bed and carries, or has
formed with it as an extension, a toothed bar or rack e, whose bottom rests upon
a solid part as, of the bed and comes between blocks a³, so as to be thereby confined
in the reciprocating or longitudinal to and fro traverse which it makes in common
with the sliding block. The teeth of the said rack intergear with the teeth of an
annular rack f¹, cut around the middle of the outer periphery f, of a rotatable
sleeve, drum or carrier f, which is mounted loosely and is capable of being rocked
or rotated within a part circular bed or bearing f³, carried on the main framing
of the machine, adjacent to the slotted work table g, which is made adjustable
relative to the body frame by means of a hand wheel g¹, and screw 2, with a plain
part swivelling in a boss g10, whilst the screw itself passes into a screw box 9,
formed in an extension of the said table, so that on the turning of the hand wheel
in either one direction or the other, the screw is rotated and the table raised or
lowered to a corresponding extent.
Both the bearing f³, and the sleeve or carrier f, are transversely gapped at f*, f³,
respectively, to admit of access being made to the hollow interior of the said
sleeve and for the purpose of introducing a tubular member, such as h¹, (part of
which is to be operated upon by the tools) of a cycle or like frame h, into the means
provided for the reception of the same and for steadying and holding it whilst the
joint is being made. This consists of a trough or semi-circular sectioned rest i,
having flanges or enlargements i¹,, gapped at, to correspond with the gaps f4, f",
and being of such a diameter as to fit into and close the open ends of the carrier
sleeve, and also with a further gapped flange it, abutting against one end of the
sleeve and being secured thereto by means of bolts, so that the tube rest and slide
are thereby made fast to one another and partake of the same rocking or part-
rotating movement. Outwards of the flanges, the rest is provided with hinged
covers or lids, having handles or grips 7, and adapted when closed over the rest
(see Figures 6, 7 and 8) to keep the tube down in its place.
The front end of the rocking sleeve carries an excentrically disposed bush or
hollow boss j the said bush being, in fact, carried upon an extension, from the
edge of the said sleeve, and within the sleeve, is an axis or spindle, free to turn
slightly therein and having at its outer end a crank 3, confined within a recess 1ª,
in the end of the boss and being provided with a peg or centre pin ja, which is thus
capable of slight vertical change of position in the recess, and whereon the pair of
arms k. k, carrying the impressing dies or tools are mounted. The arm k, may
be fixed or stationary relative to the other one k¹, which may turn upon the centre
pin, so as to admit of the jaw 3, at its upper end being brought nearer to, or taken
further away from, the jaw 2, at the top of the fixed arm for varying or adjusting
the grip or nip of the impressing tools on the parts being joined. The closing
together of the jaws for increasing the grip is effected by means of a rotating
screw, passed through a screw box, on the tail end 6, of the movable arm,
and having its end 7, impinging upon a bearing blocks, carried by the tail or
lower end of the fixed arm, and being formed with a foot or extension, which
provides an extended bearing for the impinging end of the screw whilst in order
to allow for the expeditious opening out of the jaws on the completion of a joint.
or to admit of the same being fully opened without having to turn back the screw
for a considerable distance, this bearing block is made to slide vertically up the
inside of the arm, by being carried upon a pin or stud 10, working in a vertical
clearance or gap k, of such a width that the end of the screw, may easily pass
therethrough. A spring 12 encircles the stud (on which a washer 13, is also
threaded) and by its expansive action, serves to stiffen the movement of the bearing
block. By this arrangement, when the jaws require to be opened, the screw has

page_text: only to be slacked back just sufficient distance to clear the foot of the block, when
the said block can be raised, leaving the bottom portion of the gap All, open and
into which the end of the screw can pass (as seen in Figure 15) on the opening
out of the jaws by the turning of the movable arm on its joint.
The jaws of these adjustable arms are curved and are so arranged that the axis
of them shall come in the same axial line as the common centre of troughed tube-
rest, the rocking sleeve and its bearing, so that a tube placed within the aforesaid
also comes within the nip of the jaws, wherein the half die plates m, are mounted
and secured by screws m'. These plates in the form shown in Figures 17 to 19,
are pierced with a number of annular series of holes m² (corresponding to the creas-
ings or annular impressions to be made) and through which portions of a number
of roller contacts or balls of hardened steel m³, constituting the impressing or
grooving expedients, extend, being kept in position and adjusted when required
by screws mt, which screw into the holes m², and have their inner ends m³, sunken
to receive the ball contacts which are free to revolve or roll in their respective
containing chambers,
Assuming that the parts of the machine are in the positions represented in
Figures 1 and 2, and that a joint or junction between a tubular member of a cycle
frame and one of the junction lugs requires to be made by forming impressed
annular bulgings in both parts, the machine is moved by hand or otherwise, to
such a position that the gaps f5, 3, in the walls of the rocking carrier f, and the
flanges, of the tube rest i, coincide with the gap f, of the bearing f³, as
represented in Figure 4. The covers, are then turned back as in Figures 9
and 10, and next the tube h', forming a part of a cycle frame which is held
stationary by being bolted or otherwise secured to the table g, and whose end tele-
scopes or sockets into a junction lug such as h³, is dropped into or slid onto the rest,
being further steadied in this position by turning over the lids, whose insides are
channelled to fit onto the tube, as shown in Figures 7 and 8. The lug³, telescoped
by the tube is now brought between the half-section dies m, in the jaw ends 2, 3,
of the tool arms or levers k, k¹, the jaws being brought concentric with the lug,
should they not be so in the first instance, by bodily raising or lowering the arms
by moving the crank, carrying the centre pin jo, to the required extent within
the limiting recess j. This adjustment having been effected, the crank is retained
in its adjusted position by the jaws being made to approach one another and close
around the lug so as to bring the impressing rollers into intimate contact there-
with, by screwing in the screw k. The driving band is now thrown onto the fast
pulley and the pinion a, is rotated, communicating its motion to the toothed
wheel b, which in turn, by means of the connecting rod c, transmits a traversing
movement to the sliding block d, and to the rack e, inter-gearing with the toothed
annulus f, of the carrier sleeve f, which is caused to rock or make partial rotation
within its bearing f³, and to carry with it, the stud or centre pin 7, whereon the
tool arms are mounted. The consequence is that the jaws of the arms and the
impressing roller contacts thereof make corresponding partial rotations or are
rocked backwards and forwards around the stationary lug or tube end as a centre,
which are thereby annularly creased or inwardly impressed at separated points,
the number of impressions corresponding to the numbers of rows of contacts
mounted in the dies, and as the impressing proceeds and the grooves or impres-
sions become deeper, the contacts are made to follow them up by the jaws being
made to gather closer around them by turning the screw, more and more inwards
and causing the tail ends of the arms k, k¹, to become further separated.
?
When the metal of the telescoping parts has been sufficiently bulging inwards
to form a secure joint, the screw 4, is slacked back sufficient to clear the foot
extension of the bearing block 8, which is then slid upwards, when the jaws open
out and admit of the joined parts being removed.

page_text: Figure 20 represents a side elevation and back and front edge views of a modified
form of die sections and Figure 21 represents views of the dis-assembled parts.
In this arrangement, each die and section, of which any suitable number may
be employed, according to the number of grooves to be formed, consist of two
opposed plates m¹, m², secured together by screws m³, or otherwise and having
their curved edges m', formed with corresponding half sinkings m, which, when
brought together, form nearly spherical chambers for containing the ball contacts
or impressing rollers m. These sections are let within the jaws, with the edges m*,
coming flush or nearly so with the inside faces thereof.

receive contact rollers m¹, which have pivots or trunnions m², adapted to turn
freely in suitable bearing gaps made to receive them in the die plates.

of a series of fixed pegs ml, screwed into or otherwise secured to the die plate m,
and having their acting ends m6, extending slightly beyond the inside periphery
of the said die plate.

ribs or lengths of metal let into the die plates, and which may either be fixed as
shown, or may be provided with trunnion or other ends to admit of them rotating
within suitable bearings.

In these said Figures 28 to 33, h¹ is the frame member, ² the lug or junction
piece, internally telescoped by the end of the tube, and 3 is the anvil located inside

annular channels or grooves formed around it at h, and into which the inwardly
bulged parts h, he, of lug and tube end respectively are forced by means of impress-
ing contacts m', of the dies m, held in and moving with the jaws 2, 3, of the rock-
ing arms, as previously described.
I wish it to be understood that my invention is also applicable to the production
of brazeless joints of other types than those illustrated in Figures 28 to 33, such
as those in which no internal liner or anvil is employed or in which end or other
parts of the lug are spun or rolled over outwardly bulged ribs or like formations

kis the fixed jaw or yoke fitted with a series of roller contacts m, fitted in sink-
ings m', and retained in position by plates m², and provided with depending
cheeks, or being of a bifurcated construction with the lower ends having curved
gaps, adapted to receive the trunnions, on the sides of the body part 16, of
the other portion k¹, of the tool, carrying the adjustable portion m³, of the die,
which also has a roller contact m+, and is provided with a screw stemi m³, adapted
to take into a screwed hole ki, at the upper end of a rotatable stems, carried and
capable of swivelling in the hollow end of the said body 6, and being provided
with a keyed-on grip or handle k, for facilitating its rotation, in order to bring the
adjustable jaw closer up to,, or further away from, the tubular member encircled
by 'the fixed jaw.
The stem swivels in an encircling bracket A, provided with a socket Z", adapted
to fit onto the excentrically disposed centre on the end or face of the rotating tool
carrier or rocking slide of the machine, although I wish it to be understood that
this modification may be readily employed as a hand tool in which case the stem
would be removed from the bracket and gripped by hand for working the jaws
to and fro around the parts to be united as a centre.
Instead of carrying the impressing dies in one fixed and one movable jaw, 1
may employ two movable jaws, both of them being operated through a single screw
or other equivalent expedient which draws both the jaws together and brings the
dies upon the tubular articles under operation. Or instead of a screw, the movable
jaw or jaws may be opened or opened and closed by toggle or knee joints, such
opening or gradual closing of the jaws may be performed automatically by the
motion of a lever or link actuated from a main driving shaft or rod or other part,
which gives to a pawl wiping over a ratchet wheel, a rocking or intermittent or
"continuous feed movement as the creasing or inward bulging proceeds.
As an alternative, the frame carrying the work or tubes under operation may have
a. partial rotation given to it, whilst the jaws and other parts may remain station-
ary so far as rotary motion is concerned. And instead of one or both the jaws or
half dies swinging from a pivot and opening angularly they may be arranged to
work upon a horizontal or straight bed, the outer framing or guides for the rock-
ing rest being provided with a suitable gap or gaps to admit of the lateral intro-
duction of the work.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I am aware that balls
have been used in the jaws of grooving tools for making brazeless joints for cycle
frames and I make no claim broadly to the use of balls in such tools, but I declaré
that what I claim is:-
First In machinery for making brazeless joints between telescoping tubular
parts by forming annular impressions or creases around the said parts, carrying
the dies or impressing tools by arms or levers, provided with a screw or like means
for closing together or opening the jaws wherein the said tools are fitted, sub-
stantially as and for the purpose as described and set forth.
Secondly: In machinery for making brazeless joints between telescoping
tubular parts by annularly impressing or creasing the metal, mounting the adjust-
able arms or levers, carrying the creasing or impressing dies or tools, upon a boss,
stud or equivalent centre, excentrically disposed upon the end of a carrier or sleeve
capable of making a rocking, part-rotating or rotating movement, substantially
as described and set forth.
Thirdly-In machinery for making brazeless joints between telescoping
tubular parts by annularly impressing or creasing metal, excentrically mounting
the adjustable arms or levers which carry the creasing or impressing dies or tools,

ment is imparted by a toothed annulus or toothed wheel in connection with it,

page_text: being engaged by a traversing rack, to which motion is communicated by a crank
or other suitable expedient, substantially as described and set forth.

ceding claim, the combination with the working tool carrier or slide, mounted and
working in a bearing on the,,bed of the machine, of a tube rest, having steadying
lids at its ends and bolted to and rocking with the carrier, and an adjustable work
table arranged in proximity thereto, substantially as and for the purpose described
and set forth.
Fifthly In machinery for making brazeless joints as referred to in the pre-
ceding claim, the construction, arrangement and combination of the adjustable
tool carriers, or levers, with the closing screw and its sliding bearing block, sub-
stantially as described and set forth.

ceding claims, the construction of the impressing or creasing dies consisting of
sectional-die plates fitted with rolling or fixed contacts, in the form of balls, rollers,
pegs, ribs or equivalent expedients mounted and retained in position by the means
and in the ways substantially as herein described and set forth in Figures 13 to 27.
Seventhly The modified form of adjustable tool or die carrier, so constructed
as to be capable of being used as a hand-tool substantially as and for the purpose
