Improvements in Machinery or Apparatus for the Manufacture of
Rims for Cycle and other like Wheels.
I, CARL RISSMANN, of 39, Calenberger Strasse, Hannover in the Empire of
Germany, Cycle Manufacturer, 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 machinery or means for the making of the rims of cycle
and other like wheels, and consists in shaping the same into the desired section
direct from a band of steel or a coiled band of steel of the desired breadth by
passing the same through cross rolls or pairs of rolls arranged in horizontal and
vertical directions.
During the fabrication of the said rims, the strips after fashioning are cut off at
the desired length, coiled into rings and brazed.
Figure 1 of the accompanying drawing represents in longitudinal vertical section,
partly in elevation a machine for the production of cycle wheel and other like
rims.
Figure 1 represents a cross section of the rim produced by the said machinery
upon an enlarged scale.
Figure 2 represents a topside plan of Figure 1 with the upper rollers removed.
Figure 3 is an elevation of a part of the left-hand end of the machine.
Figures 4 to 11 inclusive represent parts of the machine or details thereof
separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
In the longitudinal vertical section Figure 1, a, a, b, b', d, d' are three horizontal
pairs of rollers, which are represented in detail Figures 4, 6, 8 and 9, and c, c', are
a pair of vertical rollers.
These said upper rollers are mounted or turn within blocks or bearings a³, b², d³,
fitted within gaps m', formed within bearings or holster sides m, m, forming the main
framing. a, 63, d³ are hand wheel screws taking through cross heads a, b, d.
The lower sets of rolls are set within bearings and made fast upon axles a³, b³, d³,
provided with gearing as hereinafter described.
The top rollers a, b and d are threaded upon spindles aº, 6º, d³ and are prevented
from turning by feathers or squares on the said spindles taking through gaps or
squares in the middles of the rolls. Also threaded upon the said last named
spindles or axles, and coming between the side framings m, m, and the adjustable
blocks a, b, d, are cone bosses or distance blocks k, k¹, the latter fixed to one of
the side framings whilst the others are removable for the removal of the upper
rollers, and the replacement of the fresh ones for rolling different sections.
Lignable with the passes and in front of the rolls, and carried by the fore part of
the fixed framing is a guide framing, through which the strip p, to be subsequently
fashioned into the desired section is passed.
Thus a strip p is fed forward from a roller, bobbin or the straight and delivered
upon the plate or bed u, between the angles o. On the underside or the bed plate u,
is a screw box or screw nut u', having an adjustment screw u², working therethrough
and which is carried by the brackets q', adjustable on the framing.
The angle irons o, are fixed to the frame members o¹, which are capable of being
adjusted to accommodate the same to the width of the band to be operated upon by
means of adjustable set screws ut, which pass through the upright framings u³.

of the rolls, it is there affixed and held by the screws.
The
The bending arrangement y, consists of the frame t, which is connected to the
general framing m, and has rollers r, r, ro, turning upon strong centres.
roller ro, is carried by a traversing nut or screw box h, working within a slot h¹, and
propelled and repelled or vertically traversed by a rotating screw h², working
within suitable top and bottom bearings.
Thus the roller 7º, is raised and lowered according to the radius of the diameter
of the rim required, so that by raising or lowering the said roller the relative
distance between the other rollers is made and the radius changed.
In the driving part of the machinery, so is a loose pulley, and s a fast pulley,
which drives the shaft w, and this in turn drives, by means of the wheels, the
shaft w, through which are turned the rollers a¹, and 6, through the wheels
and . The wheel drives the wheel 2, and turns the shaft w², which turns the
vertical roller c, c, by means of the bevel wheels 1, l', whilst the roller d', is driven
by the spur wheel d.
The metal band under cross shaping is fed through the pass x, disposed between
the angles o, and the plate or rest bed u, and lignable with the pass of the
rollers a, a'.
On the passage of the strip through the first pair of rolls, it acquires the trough
figure as represented in Figure 4, and then on passing through the second pair of
rolls b, b', it takes the figure as in Figure 6, and after passing through the pair of
vertical rolls c, c¹, it acquires the section as in Figure 8, and then after passage
through the last set of rolls d, d', it acquires the cross sectional shape as in
Figure 9.
The
It may be observed that after passing through a third pair of rolls c, c', the band
reaches the fork e, having branches e¹, and which fork is mounted at
9. g.
branches e', of the forks e, act as internal supports for the opposite inner sides of
the rim to be formed during the rolling process (see Figure 9).
Figure 7 is a cross section of the horizontal rolls c, c', best seen in Figures 1
and 2. It also shows the mandril piece c', and the inner end of the fork e.
Figures 12 to 14 represent a roller drawing plate f (also shown in dotted lines in
Figure 1), which is used for giving beaded edges to any cross sectioned strip,
subsequent to the formation of the rim, instead of the same being turned over and
flattened as in Figure 9, which said roller drawing plate consists of a lower plate f¹,
connected to the sides m, and having disposed at a short distance above the plane
of f¹, a second plate fo, with screw bolts 2, passing through them, and having
threaded upon the said bolts, and located between the plates f¹ and f° outer edge
curling rollers f³, and situated as shown in Figure 13, a pair of depending inner
rollers, so that on the said sectional metal emerging from the end set of rolls
and then being directed through the beading plate, the edges of the metal are
rolled over.
It will be understood that the last pair of rolls will be changed, so as not to turn
the edges of the metal upon themselves, as the said edges require to be left intact
for beading.
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 machinery for the manufacture or cross shaping of cycle and other
wheel rims, consisting of a series of horizontally and vertically disposed rolls
suitably shaped so as to act in a transitional and successive manner upon the strip
under operation, substantially as described and set forth.
Secondly. In machinery for the manufacture or cross shaping of cycle and other
wheel rims, the employment of horizontally and vertically directed rolls in pairs
which act upon a fed strip in a transitional and successive manner, in combination
with an adjustable rest-plate lead, or in combination with the radial or ring-bending

page_text: device y, or in combination with the edge beading device f, substantially as
described and set forth.
Thirdly. The combination with machinery for the manufacture of cycle and
other wheel rims having cross-shaping rolls, and gear arrangements and appliances
