PROVISIONAL SPECIFICATION.
Improvements in the Rollers for Guiding and Traversing the
Leathers of Noble's Combs.
We, ALBERT EDWIN CRAVEN of 6, Gladstone Street, Allerton, near Bradford,
in the County of York, Mechanic, and JOHN GARGAN of 18, Warrington Street,
Allerton aforesaid, Combing Overlooker do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the traversing rollers or guide rollers
upon which the drawing off leathers are mounted and its primary object is to
prevent fibres and other foreign matter getting into the bearings of said rollers
which in the present form of construction is liable to occur and by retarding or
stopping said rollers increase the strain and wear and tear upon the drawing off
leathers.
For this purpose we prefer to make the flanges of said guide or traversing rollers
solid with or rigidly connected to the rollers. And to allow the leathers to be
readily taken off the pair of the rollers consisting of a flanged and unflanged roller
we mount such rollers on separate stud plates. To prevent fibres or dirt working
into the top of the bearing we secure the rollers upon their studs by means of a
screw screwed into or upon the top of each stud and we form a recess in the top of
the roller to receive the projecting portion of the screw. To prevent fibres and
dirt entering at the lower end of the roller bearing we form an annular projection
on the underside of the roller and we enlarge the bearing hole so that this
projection passes over and surrounds the collar of the stud. As an additional
prevention an annular projection may also be formed on the stud plate or a recess
may be formed therein to receive the annular projection on the roller.
The guide roller usually fixed to a stud plate on the steam chest we prefer to
mount on a stud plate secured to the traversing table as we find the stud plate on
the steam chest conducts a considerable amount of heat from the said chest to the
leather.

Improvements in the Rollers for Guiding and Traversing the
Leathers of Noble's Combs.
We, ALBERT EDWIN CRAVEN of 6, Gladstone Street, Allerton, near Bradford,
in the County of York, Mechanic, and JOHN GARGAN, of 18, Warrington Street,
Allerton, aforesaid, Combing 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 :-
This invention relates to improvements in the traversing rollers and guide rollers
upon which the drawing off leathers are mounted, and its primary object is to
prevent fibres and other foreign matter getting into the bearings of said rollers

stopping said rollers and consequently increasing the strain and wear and tear upon
the drawing off leathers.
For this purpose we prefer to make the flanges of said traversing rollers solid
with or rigidly connected to the rollers. And to allow the leathers to be readily
taken off the pair of the rollers consisting of a flanged and unflanged roller we
mount such rollers on separate stud plates. To prevent the fibres or dirt working
into the top of the bearings we secure the traversing rollers upon their studs by
means of a screw screwed into or upon the top of each stud and we form a recess in
the top of the roller to receive the projecting portion of the screw.
To prevent
the fibres and dirt entering at the lower end of the roller bearing we form an
annular projection on the underside of the roller and we enlarge the bearing hole
so that this projection passes over and surrounds the collar of the stud.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a diametrical section of a flanged traversing roller and a
plain guide roller.
Figure 2, represents a sectional plan of the same on the broken line a, b
Figure 1.
Figure 3, represents a separate view of the traversing roller, and Figure 4,
represents a plan view of the same.
The studs A, A2 upon which the flanged roller B and the plain roller B² are
respectively mounted are fixed upon separate stud plates C, C² secured to the
traversing table D (Figure 2). The stud A is a little shorter than the roller B
and the latter is recessed at the top to receive the head of the screw E, screwed
into the centre of the stud for the purpose of keeping the roller upon its stud. In
the case of the roller B² this screw is not required as the flange F of the roller B
prevents B being lifted off its stud. A lubricating hole G is formed in the top
of B2 and a similar hole G2 is made through the head of the screw E. Each of
the rollers has an annular projection H at the bottom surrounding the collars J of
the studs.
In
It is obvious that the roller B may have a recess at the top and be secured upon
its stud by a screw similar to E with the head of the screw lying in said recess.
this case the screw E in the stud A may be dispensed with.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. A flanged traversing roller for the leathers of Noble's combing machinery
having an annular projection at the base, or an equivalent recess, adapted to
surround a collar on the stud upon which said roller is mounted and having a recess
at the top to receive the head of a screw fitted in the top of said stud, substantially
as herein shown and described.
2. The combination with said flanged roller, of a guide roller having a recess at
the base to surround a collar upon the stud upon which it is mounted, substantially
as herein shown and described.
3. A guide roller for the leathers of Noble's combing machinery having an
annular projection at the base, or an equivalent recess, adapted to surround a
collar on the stud upon which said roller is mounted and having a recess at the top
to receive the head of a screw fitted in the top of said stud, substantially as herein
shown and described.
