PROVISIONAL SPECIFICATION.
Improvements in the Drawing-off Rollers of Noble's Combing
Machines.
We, GEORGE HENRY JOWETT, of 34, Stephenson Street, Great Horton, near
Bradford, in the County of York, Overlooker, and ISAAC SHARP, of 6, Ramsden
Terrace, Great Horton, aforesaid, Mechanic, 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 reduce the power required to drive the press
rollers and also to equalise the wear and tear on the fluted portion.
For this purpose we make the fluted portion of the press roller in the form of a
shell or sleeve and mount it upon a spindle or arbor fixed in any convenient
manner in the same position as the ordinary press roller. The fluted shell is made
to revolve freely upon this spindle and in the case of a vertical spindle it may be
lubricated by means of a duct or channel at the top.
The spindle may be made longitudinally adjustable so that different parts of the
sleeve may be exposed to the wear and tear of drawing off the fibres. Or the
sleeve itself may be adjusted longitudinally upon the spindle by means of washers
or in any other convenient manner for the same purpose.
The sleeve may be mounted on cones or other adjustable bearings on the
spindle.

Improvements in the Drawing-off Rollers of Noble's Combing
Machines.
We, GEORGE HENRY JOWETT, of 34, Stephenson Street, Great Horton, near
Bradford, in the County of York, Overlooker, and ISAAC SHARP, of 6, Ramsden
Terrace, Great Horton, aforesaid, Mechanic, do hereby declare the nature of this
invention and in what manner the same is to he performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in the drawing off rollers of Noble's
combing machines, and its object is to reduce the power required to drive the press
rollers and also to equalise the wear and tear on the fluted portion.
For this purpose we make the fluted portion of the press roller in the form of a
shell or sleeve and mount it upon a spindle or arbor fixed in any convenient manner
in the same position as the ordinary press roller. The fluted shell is made to
revolve freely upon this spindle and it may be lubricated by means of a duct or
channel at the top.
Reference is to be bad to the accompanying sheet of drawings forming a part of
LP/1

page_text: 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 in which the
press roller is mounted in accordance with our invention.
Figure 2, represents a horizontal section of the same on the line a, b Figure 1.
Figures 3 to 12 are views of certain parts separately shown and hereinafter
referred to.
The driving roller A and upper and lower slides A 2 and A 3 are of the usual
form and the adjustable or sliding blocks A 4 and A. 5 are fitted in the slides in the
usual way.
The lower block A 5 has however a square hole A 6 adapted to receive
the square end B of the spindle B 2 and hold it stationary (Figure 3 represents a
separate longitudinal view of the spindle and Figure 4, is a plan view of the same.
And Figure 5, represents a separate plan view of the block Â 5).
The upper block A 4 is made with a cylindrical hole to fit the upper end of the
spindle. A collar B3 is formed on the spindle to rest upon the upper face of the
block A 5 and a washer C is mounted on the spindle over this collar. The fluted
sleeve or shell D is made with an axial hole D2 nicely fitting the spindle and its
lower end rests upon the washer C. An upper washer C2 is then mounted upon
the spindle between the block A 4 and the top of D and to prevent C2 revolving
it is provided with a projection C3 which engages the side of the rabbet e cut
across A 4. Figures 6 and 7 represent two side views at right angles to each other
of the block A 4. Figures 8 and 9 represent a side view and a plan of the washer C 2
and Figures 10, 11, and 12 respectively represent an elevation, a plan and a vertical
section of the sleeve D. The hole D2 through the sleeve D is preferably enlarged
at the top and bottom d to receive the ends of the washers C and C 2 next to the
sleeve with the object of more perfectly excluding dust and dirt.
A channel or duct a is formed down the spindle to enable the interior of the
shell D 2 to be lubricated from the top.
The shell may be adjusted longitudinally upon the spindle by substituting
washers of different lengths for the washers and C 2 for the purpose of exposing
different parts of the fluted portion to the full wear and tear of drawing off the
fibres. Or the spindle B2 may be made vertically adjustable for the same
purpose.
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 :
In the drawing off rollers of Noble's combing machines, the construction of the
press roller, substantially as herein described and illustrated in the accompanying
drawings.
