PROVISIONAL SPECIFICATION.
Improvements in the Drawing Off Rollers of "Noble's" Combing
Machines.
I, JOHN CHARLES WALKER, of the Firm of John Perry, Shipley Fields Mill,
Shipley, in the County of York, Machine Maker, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in the drawing off rollers of "Noble's "
combing machines and its object is to provide an accurate, firm and durable method
of mounting the adjustable roller or the bearings of the adjustable roller.
For this purpose I mount the adjustable roller in arms hinged or pivoted to the
attachment supporting the other roller or any other convenient part and to ensure
greater precision both in adjustment and use the said arms may be rigidly
connected together. In this case I may only employ one spring and one screw or
their equivalent to adjust the pressure.
In case the said arms are not rigidly connected together I may provide a
projection on the lower arm approximately at right angles thereto extending up
above the fluted portion of the rollers to engage an adjustment screw and spring or
their equivalent situated there so as to be more conveniently adjusted.
The various parts are preferably so arranged that the leather or leathers may be
removed without removing the said arms and rollers.
Dated this 1st day of July 1893.

Improvements in the Drawing Off Rollers of "Noble's" Combing
Machines.
I, JOHN CHARLES WALKER, of the Firm of John Perry, Shipley Fields Mill,
Shipley, in the County of York, Machine Maker, 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:-
Noble's "
This invention relates to improvements in the drawing off rollers of
combing machine and its object is to provide an accurate, firm and durable method
of mounting the adjustable roller or the bearings of the adjustable roller.
For this purpose I mount the adjustable roller in arms hinged or pivoted to the
attachment supporting the other roller or any other convenient part, and to ensure
greater precision both in adjustment and use the said arms may be rigidly connected
together. In this case I may only employ one spring and one screw or their
equivalent to adjust the pressure.
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 an elevation of a pair of drawing off rollers mounted in
accordance with my invention, with the piece A by which they are attached to the
combing machine shown broken away as well as the driving shaft A'.
Figure 2, also represents an elevation of the same looking towards the right
houd of his 1

page_text: Figure 3, represents a section of Figure 1 on the broken line a, b.
Figures 4, and
represent detail views hereinafter referred to.
The bearing brackets B and B are connected together in the usual way by the
bar B2 and the driving roller B³ is as usual mounted in bearings B* formed in these
brackets.
The bar B2 is made with two lugs B', B' to which the arms C, C are pivoted by
the pins C¹ C¹ and these arms are connected together by the cross bar or coupling
bar C2. The bearings C3, C³ for the adjustable roller C₁ are secured to the arins C
by set screws C5 passed through the projections C on said bearings into the arms C.
Figure 4, represents a separate elevation of said arms and cross bar with the
bearing C on the lower arm omitted. Figure 5, is a plan view of the same.
The bearings C³ lie in the slot Be formed in B and B and an adjustment screw B'
and spring B of the usual type is arranged in the bearing bracket B to bear
upon C to press the roller C₁ towards B³.
An adjustment screw and spring may be fitted in the bracket B' to bear upon
the lower bearings C³. In this case the cross bar or coupling C² connecting the
arms may be dispensed with.
It is obvious that the lugs B may be formed on the brackets B and B' instead
of on B2, and in some cases this is better, particularly when the cross bar C² is
dispensed with, as it enables the arm C (and bearings C³ attached thereto) to be
removed with the bracket B in the usual way when it is desired to change or
remove the "leather" between the rollers.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :
1. In drawing off rollers for Noble's combing machinery, mounting the
adjustable roller in bearings formed on or secured to arms hinged or pivoted to
the attachment supporting the other roller, substantially as herein shown and
.described.
2. In drawing off rollers of Noble's combing machinery, mounting the
adjustable roller in bearings formed on or secured to arms rigidly connected
together and hinged or pivoted to the attachment supporting the other roller,
substantially as herein shown and described.
