PROVISIONAL SPECIFICATION.
Improvements in the Method of Mounting Drawing off Rollers of
Combing Machines.
We, JOSEPH ROBERTSHAW and EDGAR PRIESTMAN, of Industry Mill, Thornton
Road, Bradford, in the County of York, Machine Wool Combers, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object, the arrangement and mounting of drawing off
rollers for combing machines in such a manner that, rollers and spindles as hitherto
constructed may be utilized, and the rotating spindles of both the driving and
driven rollers so protected that, the liability of fibre lapping and accumulating
around the same is obviated; and to so arrange the top bearings of the rollers,
that the lubricant is retained and prevented running on to the fluted part of the
rollers, in such quantities, as will cause the fibre to lap around same; also to
retain or lock the pressure screws by the pressure nut or screwed part through
which the pressure screw passes, in the required position, in such a manner so as
to dispense with the loose. bars now used for the purpose of keeping the screws in
position.
In carrying out this invention, the revolving rollers are mounted in suitable
brackets and rotated in the manner as hitherto, but instead of exposing the spindles
at each end of the fluted portion, they are encased by tubes forming the bearings,
which are of such length, that they extend into recesses formed in the end of each
enlarged or fluted portion of the rollers, thereby entirely covering the spindles in a
manner that, no fibre can be collected by the rotation of the same.
The drawing roller is rotated in the ordinary manner, and the bottom spindle
of the driven roller supported by a footstep, both spindles being protected by bushes
extending into recesses formed in the rollers. The top bushes of the spindles are
preferably covered with a movable cap, or may be left solid, in any case a cavity
is formed at the end of spindles for the reception of a pad of suitable felt, for absorb-
ing the lubricant fed through the cap or the like, and distributing the same
regularly to the respective rotating spindles. By filling the before named cavities
with felt or the like, the lubricant is prevented running direct down the respective
spindles to the fluted portion of the roller, thus leaving the same sufficiently dry
to prevent the fibre clinging thereto and lapping around same.
The pressure nut or screwed part through which the pressure screw passes is
divided, and when the pressure on the rollers has been adjusted to the required
degree, the screws are secured by clamping or drawing the divided nut or screwed
part together, through which the pressure screw passes, so as to bind and lock the
screw.

Combing Machines.
We, JOSEPH ROBERTSHAW and EDGAR PRIESTMAN, of Industry Mill, Thornton
Road, Bradford, in the County of York, Machine Wool Combers, 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 for its object, the arrangement and mounting of drawing off
rollers for combing machines in such a manner that, rollers and rotating spindles
as hitherto constructed and now in use may be modified and utilized, and the
rotating spindles of both the driving and driven rollers so protected that, the
liability of fibre lapping and accumulating around the same is obviated; and to
so arrange the top bearings of the rollers that, the lubricant is retained and pre-
vented running on to the fluted part of the rollers to such an extent, as to cause
the fibre to stick and lap around the same; also to retain or lock the pressure screws
by the pressure nut or screwed part of the bracket through which the pressure
screw passes in the required position, and in a manner, so as to dispense with the
loose bars now used for the purpose of keeping the screws in position.
In describing our invention in detail, reference is made to the accompanying
drawings in which Fig. 1 represents an elevation of a pair of drawing off rollers
and brackets supporting same, partly in section, and suitable for a combing machine
of the "Noble" type.
Fig. 2 is a plan of the same.
Fig. 3 is a sectional elevation of one end of a roller showing a recess such as is
formed at each end of the. rollers, between the fluted portion of the rollers and
spindles, and
Figs. 4 and 5 are detached details showing one arrangement by which the
pressure screw may be retained.
In carrying out this invention, the revolving fluted rollers A, and B, are mounted
in suitable brackets C, and C, and the said rollers having spindles forming part
thereof are rotated in the manner as hitherto, but instead of exposing the revolving
spindles A1, A2, and B1, B2, at the ends of the respective fluted rollers A, and B,
they are encased by tubes, sleeves D, D', and E, E, or the like forming the bear-
ings of the said revolving spindles and rollers; the tubes, sleeves or the like, being
of such length, as to extend into recesses F, such as shown by Fig. 3 formed in
the ends of the fluted rollers A, and B, thus by the tubes or the like and recesses
entirely covering the rotating spindle portions of both the driving and driven
rollers, in a manner that, no fibre can be lapped or collected around the rotating
spindles.
The rotating spindle A³, of the fluted drawing off roller A, is extended and driven
in the ordinary manner, and the rotating spindle B2, of the roller B, is supported
by a footstep in bracket C, the rotating spindles at both ends of the rollers
being protected in the manner as before described.
The top tubes or sleeves D, and E, are preferably covered by movable caps G,
and H, or the ends may be left solid, in any case a cavity J, is formed between the
ends of the rotating spindles A, and B', and the caps or the like, for the reception
of a pad of suitable felt inserted for the purpose of absorbing some of the lubricant
fed through the hole K, in each cap.
Some of the lubricant passes down the centre holes L, L, escaping through
holes M, M, for lubricating the bottom rotating spindles A2, and B2; the lubricant
absorbed by the felt in cavities J, distributes it gradually so that it does not run

page_text: down to the fluted portion in such quantities as to cause the fibre to cling to, and
lap around the rollers.
Pressure is applied to the rollers A, and B, by screws R, and springs S, in the
manner as hitherto, but in order to retain the necessary pressure on the rollers by
preventing the screws R, turning or unscrewing, caused by the vibration of the
machine, as is now the case, we divide the nut T, at T, or when the screw is
threaded through the bracket, it is divided at T2. A screw U, is passed through
the bracket and nut T, in a manner so that, when the screw U, is "screwed up
the nut T, is drawn together and the pressure screw R, secured; or when the
screw R, is threaded into the bracket C, or C, then on "screwing up" the screw U,
the pressure screw R, is gripped by the contraction of the bracket and held in
position.
"
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is:-
1. Drawing off rollers having recessed ends at F, into which the roller bearing
sleeves extend, combined with tubes or like bearings of such length as to extend
into the recesses and protect the revolving spindles A¹, A³, B¹, B³, all being arranged
substantially in the manner as hereinbefore described and shown, and for the
purpose as hereinbefore set forth.
2. Drawing off rollers arranged substantially in the manner as before described,
combined with felt enclosed in cavities J, for the purpose hereinbefore set forth.
3. In drawing off rollers the securing of the pressure screws by the clamping or
gripping of the same, substantially in the manner as herein before set forth.
