Machines and other similar Rollers.
We, EDWIN GAUNT, Spinner, and WILLIAM FIRTH, Foreman Mechanic, both of
Grangefield Mill, Stanningley in the County of York, do hereby declare the nature
of this invention to be as follows:-
«
The feed rollers of carding machines and other similar rollers generally have their
teeth attached in the form of card cloth, or Garnett teeth are arranged in a spiral
groove in such rollers, or such teeth are separately fixed in the form of pins. Our
improvements consist in making such teeth on rings preferably cast or stamped and
adapted to be mounted on said rollers, thus providing much stronger teeth than
hitherto, though equally effective and at cousiderably less cost.
To carry out our improvements we preferably cast the rings of teeth with a spacing
flange or rim adapted to rigidly keep each ring the requisite distance from those on
either side. The said rings are secured by a key fitted along the roller and corre-
sponding keyways formed in each ring, or they may be clamped together between a
collar on one end of the roller and a screw or nut at the other, or such rings may be
fixed in any other convenient manner.
As an alternative arrangement the said spacing pieces may be separate rings
alternately mounted on the roller with rings provided with teeth in which case the
said toothed rings are preferably stamped.

We, EDWIN GAUNT, Spinner, and WILLIAM FIRTH, Foreman Mechanic, both of
Grangefield Mill, Stanningley in the County of York, 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:-
The food rollers of carding machines, and other similar rollers used in machinery
for operating upon fibrous substances, generally have their teeth attached in the form
of card cloth, or "Garnet" teeth are arranged in a spiral groove in such rollers, or
the teeth are separately fixed in the form of pins. Our improvements consist in
making such teeth in solid rings proferably cast or stamped and adapted to be
mounted side by side on said rollers, thus providing much stronger teeth than
hitherto, though equally effective and at less cost, besides reducing the liability of the
fibres "lapping" round such rollers.
To carry out our improvements we preferably cast the rings of teeth with a spacing
flange or ring adapted to rigidly keep each ring the requisite distance from those on
either side. The said rings are secured by a keyway formed along the roller and a
corresponding key projecting inside each ring, or they may be clamped together
between a collar on one end of the roller and a screw or nut at the other, or such
rings may be fixed in any convenient manner.
As an alternative arrangement the said spacing pieces may be separate rings
alternately mounted on the roller with rings provided with teeth in which case the
said toothed rings are preferably stamped.
To fully describe our invention reference is to be had to the accompanying drawing
forming a part of this specification, in which similar letters of reference indicate
corresponding parts in each of the figures.
Figure 1, represents a section of a roller showing a full view of one of the rings.
Figure 2, is an elevation of such ring. Figure 3, is a diametrical section, and
Figure 4 represents a similar section of a toothed ring without the spacing rim, which
is shown separately in section in figure 5.
The roller A is represented with a keyway along it and a key B is formed inside
the ring C, adapted to fix said keyway.
The teeth D are cast with the ring represented by figures 1, 2, and 3, and in figure 4
such teeth are stamped with the ring, the sectional form being slightly modified for
this purpose, and a separate ring G is employed to hold the toothed rings the requisite
distance apart. To prevent the rings moving longitudinally a nut is preferably
provided at each end of the roller and the rings clamped between them, or the nut at
one end may be replaced by a shoulder.

page_text: Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we would have it under-
stood that we do not broadly claim the use of rings with the teeth or pins separately
socured therein, but declaro what we claim is :-
The use of solid rings of teeth in the construction of the rollers specified,
substantially as heroin shown and described and illustrated in the accompanying
drawing.
