Improvements in and in Machinery for the Manufacture of the Rims
or Fellies of Wheels
I, ROBERT FREDERICK HALI, Managing Director of The Cycle Components
Manufacturing Company, Limited, of "Ferndale,' Church Road, Moseley, near the
City of Birmingham, 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 has relation to the manufacture of the rims or fellies of wheel-
for cycles, common road vehicles and the like, principally of that type in which
pneumatic or soft tyres are employed, and also to machinery to be employed, in the
said manufacture
The said machinery is adapted for shaping or fashioning flat endless bands o
rings of sheet metal, either having brazed joints or being made weldless, although
the same may be applied for the shaping of strips in successive operations and my
invention consists primarily in mounting a series of revoluble rolls upon a rotating
table, which rolls are presented alternately to the periphery of a revoluble roll
having a mounting which is stationary relative to the other iolls, and on the said
revoluble rolls which are carried by the table being brought alternately up to roll
mounted in fixed bearings carried by the bed (and which I shall hereafter call
the fixed roll) the said rolls thus approached have motion imparted to them
through a principal divided shaft, provided with a self-acting clutch, acting
through the medium of lugs or inclined planes carried by the bracket of the table
rolls, of which the table is rotated by hand-for bringing the rotating-table or
serial 1olls up to the fixed roll, after an endless and flat sectioned band or hoop to
be shaped has been placed in position
Figure 1 of the iccompanying drawings represents a plan of the machine, but
with the clutch mechanism removed to show the relative position of the rotating
table and revoluble 1olls carried by it, and the single fixed and revoluble roll
cared by the bed
Figure 2 represents a vertical section of the machine upon the dotted lines X,
Figure 1, but with the self acting clutch mechanism, which is also shown in section,
added
Figure 3 represents the clutch part of the mechanism upon the dotted line A
Figure 2
igure 4 is a horizontal section upon the dotted line B Figure 2, showing the
gearing of the table rolls and the fixed roll
Figure 5 is a vertical section, with portions in elevation, of the rotating table and
its gearing separately
Figure 6 represents an edge view, Figure 7 a side view, Figure 8 a section, and
Figure 9 a full-sized cross section, of the endless and flat-sectioned band or hoop of
sheet metal from which the rim is to be formed, whil t Figure 10 is a section of the
periphery of the No 1 table roll, Figure 11 a section of the periphery of the
No 2 table roll, Figure 12 a section of the periphery of the No 3 table roll and
Figure 13 a section of the periphery of the No 4 table roll, and Figure 14 is a
section of the periphery of the fixed roll
Figure 15 shows a section of the band after it has been operated upon by the
No 1 table roll and the fixed or No 5 roll, Figure 16 is a section of the said band
after being acted upon by rolls 2 and 5, Figure 17 a section after being operated

page_text: upon by rolls 3 and 5 and Figure 18 shows a section of the finished rim after it has
been operated upon by rolls 4 and ǝ
The same letters of reference indicate corresponding parts in the several figures
of the drawings
1, 2, 3 and 4 are revoluble and serial rolls, each mounted on a shaft a, working
within an excentric bearing b, fitted and adjustable within a strap or split arm cl
of the top part c², of a rotating table c, made fast to a depending and central shaft
or axis c, having at its lower end, a worm wheel c', with the teeth intergearing
with a worm d, carried at the inner end of an axis or spindle d', which works within
the bearings d², of brackets d³, bolted to the underside of the circular bed plate e,
and has a hand wheel d, made fast to its outer end d³, for the purpose of revolving
the worm for turning the rolls 1, 2, 3 and 4 alternately to the periphery of the fixed
10ll 5
The excentric mounting of the shafts of the rolls is for the purpose of finely
adjusting their positions or setting the same up Thus, each of the brackets c¹, is
split at c, and through the lug c, thus formed, a bolt e, passes and takes into the
solid part c
By loosening the bolt or pin, the excentric can be turned, and by it, the roll is
set or adjusted to a great nicety This done, the excentric bearing is clamped in
position by the screwing up of the said bolt
The revolving table, through which the shafts a, pass, is supported upon its
underside by a stepped plate e, whilst the lower ends a', of the said shafts a, of
each table roll or rolling die, which have pinions f, made fast to them, work within
like excentric bearings and thrust blocks g, which are carried within split brackets g',
alike unto the brackets c', at the other ends of the spindles, and which excentiic
bearings and thrusts are supported by a disc or bracket table c
The bed plate e, is supported by legs e2, whilst the bracket c², which is made fast
to the central shaft 3, alike unto the table, has inclined planes or snugs h, up and
over which the pawl arm 2, jointed at ', and having a roller or stud 2, engaging
in the annular groove, of a rising and falling coned collar 1, upon the rolls driving
shaft, having a feather k¹, travels and passes m is a lever, with the short
arm m³, taking and bearing upon the conoidal part, of the collar, and with the
Joint m², carried by a bracket m³, made fast to the principal roll driving axis
which is divided at k², and connected through the medium of a clutch box n and
split and ring band clutch o, located within the interior of the said clutch box and
adapted to press upon the inside walls of the same and be made fast with it by the
lever m, whose long arm m, is jointedly connected to a loop or ring m³, carrying
jointed links me, forming a toggle joint, and whose ends are jointedly connected
at m² to the free ends o, of the split spring band o which has lugs o³, which drop
into like-shaped stepped sinkings n the topside of the table part m³, of the
fast bracket m³
Made fast to the principal and rotating axis k, is he roll ɔ, working through
excentric top and bottom bearings, fitted in the upper and lower branches p,
of a bracket p, made fast by bolting, to the bed plate e
The lower end of the rotating shaft h, takes its thrust in the lower excentric
bearing b, whilst the lower arm p³, of the bracket p, carries a bracket table p
Made fast to the lower part of the principal shaft k, is a toothed wheel 9, with
which the toothed wheels t, of the rotating table rolls are made to alternately
intergear
The rolls and 4 are separated by a space s, greater than the other spaces
between the rolls This is for the purpose of having a good clearance for the
introduction of the endless flat band shown in chain dotted lines t, to be fashioned
or shaped into a rim of any desired cross section

page_text: represented by the dotted lines u, in Figure 1, then drop the flat sectioned and
endless strip or band upon the bed e, (which is flush with the top of the table )
with the whole of the acting peripheries of the rolls lying above the plane of
the said rotating table and bed plate wh ch form a set for the endless band to be
operated upon, the walls of which band come between the fixed roll and the table
rolls, so that the table rolls are comprehended within the hoop
The operator now turns the hand wheel d, which rotates the worm d and thereby
slowly turns the shaft c³, through the tangent or worm wheel c', and with it the
table, brackets c', rolls 1, 2, 3 and 4 and other parts carried by it As the roll 1,
approaches the roll o, with the hoop under shaping between them, the inclined
plane h, wipes under the nose of the pawl arm 2, and the collar is lifted, and
by it the lever m forces the ring m³, laterally, and through the links or toggle
levers m, the split spring band o, is expanded and its outer periphery forced up
against the inner walls of the clutch box n, when instantly the roll end of the
shaft k, is coupled to the other and driving end and the roll is rotated and also
the roll 1, by the toothed wheel f, of the said roll 1, meshing with the toothed
wheel g, of the roll 5 and so long as the operator keeps the rolls 1 and 5 together
and the clutch lever rests upon the inclined plane h, so long will the said
pair of rolls be revolved and the strip be made to travel round and operated by
them
When the band has been sufficiently shaped to the first stage, then the operator
tuins the hand wheel and immediately the clutch operating arm passes the
inclined suug or plane h, and falls and the clutch is thrown out by the contraction
of the split ing
The rolls then cease to rotate until the inclined plane of the
No 2 roll is brought under the clutch arm and the coupling made, when the toothed
wheels fand 9 are then brought into mesh and the rolls 2 and 5 thus coupled
are then driven and the band is made to travel round and to be further shaped
by them The same operation is repeated in order to bung the rolls 3 and 4
successively up to the roll >
It is understood that any further number of she rolls may be carried by the
rotating table, in combination with the fixed he roll, and that any section other
than those shewn in Figures 1, 2 and ǝ and may be produced by varying the
peripheries of the rolls, and instead of employing she-peripheried rolls upon the
rotating table, he-1olls may be carried thereby and she roll used as the fixed one
but it will be understood that in this arrangement larger number of rolls will be
required on the rotating table in order to fetch the rim up to form by more gradual
successive stiges
One cardinal advantage in the machinery herein described is that varying sized
rings can be shaped, so long as the same are greater than the circular area
comprehended by the serial rolls, without the necessity of making any adjustment
or change of position of the rolls or other parts of the machine
The edges of the rims formed may be afterwards formed by passing the same
through special beading rolls, or beading rolls may follow the last of the series of
rolls on the table
It is obvious that section strips of the required cross section of a rim can be
produced by the machinely described as well as endless sectioned rims When
strip is required to be shaped it has to be passed as many times through the
machine as there are rolls on the rotating table The shaped strips are cut up
into the desired length, formed into ings and the ends brazed together as usual
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
clum is
