PROVISIONAL SPECIFICATION.
Improved Bearings for the Rollers of Combing Machines used in the
Treatment of Fibrous Substances.
We, JAMES RAMSDEN HOYLE and HEBDEN COLBURN, both of Globe Ironworks,
Keighley, in the County of York, Machine Makers, do hereby declare the nature
of this invention to be as follows, that is to say:--
rollers of
In connection with the bearings for the "drawing-off"
combing machines used in the treatment of fibrous substances, a great difficulty
has heretofore been experienced by the rapid deterioration of the bushes or
movable bearings through or in which the rollers' shafts rotate by reason of the
bearing surfaces" formed thereon being considerably limited in extent.
66
To obviate this defect and produce bearings which shall perform all the functions
desired of them efficiently is the object of our present invention, and this object
we attain by constructing the movable bush so that it may have a sleeve or sleeves
formed laterally (or in other position) on or secured to it, to take over a guide rod
or rods secured by screws or otherwise to the supports or bearings in which the
rollers rotate or are held.
Space is allowed for the free actions of the spring and regulating screw, and the
block through which this latter passes to act or operate the former, is altered in
shape to meet the altered forms of parts in connection with which it operates.
As an alternative method to the one above described the supports or bearings in
which the rollers' bushes are mounted may have slots formed in them for projecting
slides formed on guide plates to take through to be secured by screws or other-
wise to said bushes, in this manner the bearings surfaces for same are extended to
the outside as well as being on the inside of the supports or bearings.
Again the walls of the bearings may be cut down either straight or to form a
dove-tail slot by an extra guide piece being secured thereto in which case the side
of the bush for contact with this has a correspondingly shaped projection formed
on it or secured to it to take into this straight or dove-tail groove where it is
secured by the fixing of the detachable guide piece.

Treatment of Fibrous Substances.
We, JAMES RAMSDEN HOYLE and HEBDEN COLBURN, both of Globe Ironworks,
Keighley, in the County of York, Machine Makers, 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 connection with the bearings for the drawing-off rollers of
combing machines used in the treatment of fibrous substances, a great difficulty
has heretofore been experienced by the rapid deterioration of the bushes or
movable bearings through or in which the rollers' shafts rotate, by reason of the
'bearing surfaces" formed thereon being considerably limited in extent.
To obviate this defect and produce bearings which shall perform all the functions
desired of them efficiently is the object of our present invention, and in order that
said invention may be readily understood, we have hereunto appended sheets of
drawings illustrative thereof, in which:-
Fig. 1 is a view. as seen from above, of the parts of a combing machine necessary
to show the application of our invention.
Figs. 2 and 3 are side and top views of the rollers mounted in our improved
bearings, the same being drawn to an enlarged scale.
Fig. 4 is a sectional view on line A-B of parts shown by Fig. 3
Fig. 5 is a drawing in detail showing a part hereinafter explained.
Fig. 6 is a similar view to Fig. 3 but illustrates a modification of our invention.
Fig. 7 is a sectional view on line C-D of parts shown by Fig. 6.
Fig. 8 is a detail drawing hereinafter referred to.
Fig. 9 is also a similar view to Fig. 3 and illustrates still another modification
of our invention.
Fig. 10 is a sectional view on line E-F of parts shown by Fig. 9
Fig. 11 is a detail drawing hereinafter referred to.
Similar letters and figures of reference indicate similar parts throughout the
several views.
We attain, the object of our invention by forming a sleeve a on or securing it
to the sliding bush b, this sleeve being arranged to take over the guiding rod c
secured to the bearings on the one side and causing the bush 6 to slide against
the bearing part d on the other side of it, by these means, while we are enabled
to employ the usual sliding block f., screw g.and spring h for their well known
pressure transmitting purposes, we so secure the bush b that it is firstly held
against the tendency it has to revolve with the shaft k of the roller m, and it is
well known that the tendency to revolve (which tendency is greatly increased by
the vibratory motions of the roller m which is fluted and acts or is pressed against
the other fluted roller p) adds greatly to the source from which deterioration is
caused. If desired more than one of the sleeves a and rods c may be employed in
connection with each bush b, however we preferably only employ one such sleeve a
and rod c as shown.
As an alternative method to the one above described, the supports or bearings d
in which the bush b is mounted, may have a slot r formed in it for the projecting
slides formed on the guide plate s to take through to be secured to the bush b
by a screws or otherwise, as shown by Figs. 6, 7 and 8, in this manner the
bearing surface for said bush b is extended to the outside as well as being on the
inside of the support or bearing đ.

page_text: Again one or both of the walls of the bearing d may be cut down either straight
or to form a dove-tail slot rl (see Figs. 9, 10 and 11) by the extra guide piece t
being secured thereto, in which case the side of the bush 6 for contact with this
has a correspondingly shaped projection w formed on it to take into this straight
or dove-tail groove when it is secured by the fixing of the detachable guide
piece t by the screw t¹ or otherwise.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. In bearings of the class described a bush having a sleeve formed on or secured
to it, a rod for said bush to take over and the other parts used in connection with
these substantially as herein specified, and for the purpose set forth.
2. In bearings of the class described the combination of bushes having each a
sleeve or sleeves, rods for said sleeves to take over, sliding blocks and screws
passing through same to act on springs for transmitting pressure to said bushes,
rollers for rotating in same and parts for securing these in position substantially as
herein specified
3. In bearings for the rollers of combing machines, sliding bushes having sleeves
to take over guide rods, said guide rods, bearings for securing said guide rods and
bushes in position, rollers revolving in said bearings, and spring pressure devices
for acting on said rollers, in combination the same being constructed substantially
as herein specified.
4. In bearings for the rollers of combing machines, the combination of guide
plates having projecting slides to take and move within slots formed in the bear-
ings, said slides being fixed to the bushes, said bearings and bushes, spring pressure
devices for acting on said bushes, and rollers for rotating in same, substantially as
herein specified.
5. In bearings for the rollers of combing machines, the combination of bushes
having longitudinal projections for taking and moving within slots formed in the
bearings, said bearings, detachable guide pieces for securing said bushes in position,
spring devices for transmitting pressure to said bushes, and rollers for rotating
therein, substantially as herein specified.
