PROVISIONAL SPECIFICATION.
Improvements in Drawing, Reducing, Roving, Spinning, and
Twisting Machinery.
We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower
Green Shed, Leeds Road, Bradford, in the County of York, Spinners, and
SAMUEL THOMAS WHEATER, of 73, Copthorne. Street, Horton Road, Bradford,
aforesaid, Mechanic, do hereby declare the nature of this invention to be as
follows --
This invention relates to improvements in drawing, reducing, moving, spinning
and twisting machinery, and its object is to reduce the friction caused by the
rotation of the press rollers.
To carry out our invention we as usual mount two rollers on one spindle but
we employ a "dead" or stationary spindle, and instead of rigidly connecting the
two rollers together by the spindle as is commonly the case we mount each roller
upon "ball" bearings on said spindle. Two annular sets of balls may be used for
each bearing. The balls may lie in "races "cut in a hardened shell fitted into the
centre of the roller and adjustable ball cones of hardened steel fixed by lock
nut and washers are screwed upon the spindles for the sets of balls to revolve
upon. This arrangement permits of the rollers being adjusted longitudinally upon
the spindle.
The ball cones on the spindle may be fixtures and the ball races may consist of
hardened "cups" formed or mounted in a suitable shell and one or both of them
capable of adjustment thereon. The shell may be split or more or less sawn across
or divided parallel to its axis so that when clamped by a set screw in position in
the roller the pressure of said screw holds the adjustable cup or cups stationary
in relation to the shell. The rollers are adjustably mounted upon the shells.
Other means may be provided for locking the adjustable cup or cups within the
shell.

This arrangement permits of the rollers being adjusted longitudinally upon the

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 spindle with a pair of rollers mounted
upon it one of which is shown in diametrical section. Figure 2, represents an end
view of the same. Figure 3, represents a similar view with the spindle in section
and ball cone removed.
Figure 4, represents a similar view to Figure 2 illustrating a modified form of
bearing and Figure 5, represents a diametrical section of one roller fitted with
this bearing together with a portion of the spindle shown in full.
Although the spindle A does not rotate it may be mounted in the machine in
the usual way.
It is provided with two ball cones B, B at each end which are
screwed onto it and a lock nut C, is fitted in connection with each cone. The rollers
are made with circular recesses on each side concentric with the central hole and
hardened steel shells D are fixed in these recesses. The balls E are introduced
between the cones B, B and the shells D of each roller.
In the modification shown in Figures 4 and 5 the spindle A is made with a fixed
collar F to form the cones for the balls E and the shells D2, D2 screw into the
central hole in the roller which hole is enlarged and has a female screw thread to
fit the thread on the shells. Lock nuts C 2 are also fitted on the shells.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :
The combination with a dead spindle of two press rollers loosely mounted upon
it by means of ball bearings, substantially as herein shown and described and
illustrated in the accompanying drawings.
