PROVISIONAL SPECIFICATION.
Improvements in or appertaining to the Drawing-off Rollers of
Noble's and similar Combing Machines.
We, THOMAS HALL WHARTON and HERBERT MONIES of the firm of Wharton
and Monies, Sidney Works, Fairweather Green, near Bradford, in the County of
York, Commission Wool Combers, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in or appertaining to the drawing-off
rollers of Noble's and other similar combing machines. The pressure between
these rollers is usually regulated by means of a spiral spring at each end compressed
between the end of two slot guides formed in the bracket carrying the drawing-off
roller and the guide plates in which the adjusting screws are fitted. These screws
abut against the bearings of the adjustable roller and passing through the end of
the slots project beyond the said bracket to allow of ready adjustment. A serious
defect in this arrangement is the rapid wear that takes place at the neck of these
screws passing through the end of the guide slots and also between the bearing
block and bearing guides of the adjustable roller and the object of this invention
is to remedy these defects.
For this purpose we arrange the springs to bear directly upon the bearings of
the adjustable roller and compress them to adjust the pressure of the rollers between
such bearings and said guide plates or blocks by means of a screw fitting a thread
formed in the hole through the ends of the guide slots. The bearing blocks of the
adjustable roller are preferably made approximately the full length of the said
guide slots or considerably longer than heretofore and a longitudinal recess or slot
is formed in them to receive the spring. A mushroom shaped piece having a centre
bearing for the adjusting screw is fitted in each spring and this piece is preferably
too large to pass through the opening for the adjusting screw so that by employing
a spring which is more or less compressed within the limits of the recess or slot the
parts are retained in their relative position when the pressure of the screw is
removed. Or by forming a sliding joint in the sides of the slot or recess receiving
the spring a solid end may be provided having a bearing for the adjusting screw.
These bearing blocks may be formed separate or of inferior metal to the actual
bearings of the adjustable roller and the latter bearings may be fitted therein.

Improvements in or appertaining to the Drawing-off Rollers of

We, THOMAS HALL WHARTON, and HERBERT MONIES, of the firm of Wharton
and Monies, Sydney Works, Fairweather Green, near Bradford, in the County of
York, Commission 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 relates to improvements in or appertaining to the drawing-off
rollers of Noble's and other similar combing machines. The pressure between the
rollers is usually regulated by means of a spiral spring at each end compressed

page_text: between the ends of two slot guides formed in the bracket carrying the drawing-off
roller and the guide plates in which the adjusting screws are fitted. These screws
abut against the bearings of the adjustable roller and passing through the end of
the slots project beyond the said bracket to allow of ready adjustment. A serious
defect in this arrangement is the rapid wear that takes place at the neck of these
screws passing through the end of the guide slots and also between the bearing
block and bearing guides of the adjustable roller and the object of this invention
is to remedy these defects.
For this purpose we arrange the springs to bear directly upon the bearings of the
adjustable roller and compress them to adjust the pressure of the rollers between
such bearings and said guide plates or blocks by means of a screw fitting a thread
formed in the hole through the ends of the guide slots. The bearing blocks of the
adjustable roller are preferably made approximately the full length of the said
guide slots or considerably longer than heretofore and a longitudinal recess or slot
is formed in them to receive the spring. A mushroom shaped piece having a
central bearing for the adjusting screw is fitted in each spring and this piece is
preferably too large to pass through the opening for the adjusting screw so that by
employing a spring which is more or less compressed within the limits of the recess
or slot the parts are retained in their relative position when the pressure of the
screw is removed.
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 a
bracket or stand fitted with our improvements in which the lower portion of the
bracket is shown in section to more clearly illustrate the parts.
Figure 2, is a plan view of the same.
Figure 3, is a separate side view of one of the said long bearing blocks.
Figure 4, is an end view, and Figure 5, a plan view of the same.
Figure 6, is a view of a modification hereinafter referred to.
The bearing blocks A, A for the journals B, B of the adjustable roller C are
made approximately the length of the guide slots D, D formed in the top and
bottom arms E, E of the bracket F. The blocks A each have a slot G formed in
them with a pap H projecting from its inner end to receive the end of the spiral
spring J passed through the opening K in the end of the slot. The mushroom
piece L is introduced into the other end of the spring and the pointed inner end of
the adjustment screw M (fitting a female screw thread formed in the end of the
slot D) bears against a centre hole in the head L.
In the modification shown in Figure 6 the female thread is made in a sliding
piece L' instead of the end of the slot D and a collar N is secured on the shank of
the screw (by the pin O) to bear against the end of the slot D and prevent
longitudinal motion of the screw.
Or as a further modification by forming a sliding joint in the sides of the slot G
so as to make the length of the slot adjustable the end of such slot may be left
solid for the screw fitting the end of D to bear against it.
The block A may be formed separate or of inferior metal to the actual bearings
of the adjustable roller and the latter bearing may be fitted therein.
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. The improved construction of bearing block for the journals of the adjustable
drawing off roller having a recess formed therein to receive the spring, substantially
as herein shown and described.
2. The combination with an adjustable bearing block of the drawing off rollers,
of an adjustment screw fitting the end of the slot in which the said block is mounted

page_text: in such a manner that said screw is prevented from vibrating longitudinally when
the machine is in operation, substantially as herein shown and described and
illustrated in the accompanying drawings.
