Improvements appertaining to Combing Machines used in the
Treatment of Fibrous Substances.
We, MITHREDATH GEORGE OGDEN, of Oxenhope, near Keighley, in the County of
York, Wool Comber, and GEORGE VANHAM, of the same place, Overlooker, do
hereby declare the nature of this invention to be as follows, that is to say:―
In combing machines of the class wherein the circular comb rotates
upon its bearings it is found most desirable, that, notwithstanding the wear-
ing of said bearings and parts in contact with them, said comb should be main-
tained in a perfectly circular path around its original centre of motion in order
to be enabled to perform the functions desired of it efficiently.
To produce bearing surfaces that will automatically adjust themselves as they
are being worn down so that the rotary comb is kept in its proper path as
desired is the object of this invention, and this object we attain by forming or
securing a lateral flange upon the comb's carriage concentric with the comb and
forming the under surface of said flange at an angle to the horizontal plane so that
it may correspond with a similarly situated surface formed on the circular-fixed-
bearings beneath, while a series of antifriction balls are placed between the two
surfaces, these said balls being kept in their respective positions by the pressure
of the two faces upon them. From this it will be seen that each ball touches the
surfaces of the lateral flange and as well as its circular bearings in a point only
and that as it is free to revolve around same the path of motion described by it
will be a line.
Had such bearings to be formed so that each ball touched each surface in more
than one point, that point which described the path furthest from the centre of
motion of the comb would pass, in travelling around same, through a greater space
than that part of the ball describing a path nearer said centre so that the ball
would have to slip or glide in one part to accommodate itself to the motion of the
other part hence considerably more friction would be engendered than is the case
when said surfaces are formed so that each ball touches each one of them only in
one point in accordance with our invention as herein before described.
As the bearing surfaces are made at an angle to the horizontal plane it will be
seen that any wear thereof is compensated for by gravity, while to ensure the
comb's carriage keeping a perfectly circular path the lateral flange thereon is
made to extend into contact with circular bearings upon which it is mounted so
as to be thereby guided as desired. Or a flange may be formed on the bearings to
reach into contact with the lateral flange on the carriage for performing this
function.

We, MITHREDATH GEORGE OGDEN, of Oxenhope, near Keighley, in the County of
York, Wool Comber, and GEORGE VANHAM, of the same place, Overlooker, 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, that is to say:-
In combing machines of the class wherein the circular comb rotates
upon its bearings it is found most desirable that, notwithstanding the wear-
ing of said bearings and parts in contact with them, said comb should be
maintained in a perfectly circular path around its original centre of motion in
order to be enabled to perform the functions desired of it efficiently.
To produce bearing surfaces that will automatically adjust themselves as they
are-being worn down so that the rotary comb is kept in its proper path as desired
is the object of this invention.
This object we attain by following the method of construction hereinafter
described and illustrated by the accompanying sheet of drawings, in which:-
Fig. 1 is a sectional elevation of a sufficient portion of a combing machine to
illustrate the application thereto of our invention.
Fig. 2. is a sectional plan on line A-B of parts shown by Fig. 1.
Fig. 3 is a similar view to Fig.1, but shows the application of a part hereinafter
described.
Similar letters and figures refer to similar parts throughout the several views.
The object of this invention is attained by forming or securing a lateral flange a
upon the comb's carriage b concentric with the comb c and forming the under
surface a¹ of said flange a at an angle to the horizontal plane so that it may corre-
spond with a similarly situated surface d' formed on the circular fixed bearings d
beneath, while a series of antifriction balls f are placed between the two surfaces a¹
and d', these said balls f being kept in their respective positions by the pressure
of the two faces a and d upon them, as also by the spacing pieces 9 which are
placed between said balls f in order to keep them at approximately equal distances
from each other. From this it will be seen that each ball f touches the surface a¹
of the lateral flange a as well as the surface d' of its circular bearings d in a point
only and that as it is free to revolve around same the path of motion described by
it will be a line.
Had such bearings a and d to be formed so that each ball f touched each sur-
face a¹ and d in more than one point, that point which described the path furthest
from the centre of motion of the comb would pass, in travelling around same,
through a greater space than that part of the ball describing a path nearer said
centre, so that the ball would have to slip or glide in one part to accommodate
itself to the motion of the other part, hence considerably more friction would be
engendered than is the case when said surfaces a¹ and d¹ are formed so that each
ball touches each one of them only in one point in accordance with our invention
as hereinbefore described.
As the bearing surfaces a¹ and d¹ are made at an angle to the horizontal plane
it will be seen that any wear thereof is compensated for by gravity, while to
ensure the comb's carriage 6 keeping a perfectly circular path the lateral flange a
thereon is made to extend at a into contact with the circular bearings d upon
which it is mounted so as to be thereby guided as desired. Or a flange
formed on the bearings d to reach into contact with the lateral flange on the
carriage as shown by Fig. 3 for performing the said guiding functions.

tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a combing machine of the class described the circular comb and its bear-
ings having their surfaces formed as described and antifriction balls mounted
between them the same being constructed and arranged in combination sub-
stantially as specified.
2. In a combing machine of the class described the circular comb its bearings
and other parts constructed and arranged to operate substantially as herein
specified.
