"Improvements in Rollers for Spinning and Drawing Frames."
I, JOHN REED MILSON, Mechanic, of 4, Church Street, Bristol, in the County
of Bristol, State of Rhode Island, one of the United States of America, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement.
This invention relates to top rollers for worsted spinning and drawing frames,
and consists of a roller constructed of metal and secured in position by a metal
boss, the outer portion of the roller being flanged to receive a movable rim of
suitable material.
The invention further consists of the details of construction and arrangement
of the several parts, which will be more fully hereinafter described and claimed.
In devices of this character, as heretofore constructed, they comprised wooden
bosses which were driven or otherwise forced upon an iron arbor and covered.
with leather which was fastened in place by the application of glue to the inner
surface thereof, and required expert or mechanical skill to place it in position.
In view of the great amount of pressure that is brought to bear on this class of
devices, the leather becomes stretched, and if glued on one side, as stated, it will
loosen unequally and become blistered on the outer surface when it is necessary
to immediately replace it, in order to attain a proper operation of the machine,
and to act upon the yarn as desired.
The object of the present invention is to overcome this disadvantage by making
the rim of the roller movable and constructing it either of rubber or analogous
material so as to permit it to have a yielding movement and play.
In the accompanying drawing:
Figure 1 is a perspective view of the preferred form of roller shown ready to
be applied to its arbor.
Figure 2 is a similar view of the parts of the roller shown by Figure 1 detached.
Figure 3 is a similar view of a roller having an elastic rim applied thereto.
Figure 4 is an elevation of a part of the upper portion of a worsted spinning
or drawing frame.
Referring to the drawing, wherein similar numerals of reference are employed
to indicate corresponding parts in the several views, the numeral 1, figures 1 and 2,
designates a roller which is made in two sections 2 and 3, secured together by
screws 4. Each section is provided with a flange 5, and when the parts are united
they enclose a separable rim 6, which is loosely fitted between the flanges and has
a sliding movement or play. A metal boss 7 is located within the center of the
roller, and through a part of the said roller and boss extends a set-screw 8, which
engages a plain surface 9 on a metal arbor, to thereby hold the roller in fixed
engagement with the said arbor.
In figure 3 a slightly modified form of construction is shown, and therein the
roller 10 is made in one piece, and is supplied with a yielding rim 11 constructed
of rubber or analogous material which is also adapted to have a circular sliding
movement. In applying the rim 11 in position it yields sufficiently to be stretched

page_text: over the flanges, which are also employed in connection with the roller shown by
figure 3, and will retain its seat after being properly positioned. It will be under-
stood, however, that the yielding or elastic rim does not impinge or bear against
the outer portion of the roller sufficiently to prevent its movement around the
same.
In Figure 4 a part of a worsted spinning or drawing frame is shown embodying
the rollers in position, and therein are illustrated fluted bottom rollers 12 bearing
against the removable rims of the top rollers, as heretofore set forth. To sustain
the adjustment between the top and bottom rollers, a metal saddle 13 engages the
top arbor, and is supplied with a spring-actuated adjusting rod 14 having a set-
nut or thumb screw 15 suitably supported by an adjacent part of the machine
and acting to hold the top rollers closely against the bottom rollers. This is
merely one form of adjustment and can be varied at will, though is especially
applicable to the form of device heretofore set forth.
The form of top roller herein before set forth does not require as much power.
to operate it as in the forms heretofore constructed; and also a cushioning or
yielding contact of the bottom and top rollers is had while in motion. Further-
more, the top roller set forth has a longer life than those heretofore used, and
it will not require to be replaced as often. The form of rimi herein described
will re-adjust itself in normal shape after leaving the nip of the two rollers, and
this is especially true where the elastic rim is employed. Modifications in detail
may be resorted to without departing from the spirit of the invention or sacrificing
any of its advantages.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A top roller for the purpose set forth having a removable rim, substantially
as described.
2. A top roller for the purpose set forth having peripheral flanges, and a rim
movably held therein, substantially as and for the purposes specified.
3. A top roller for the purpose set forth formed of two parts and providing
a peripheral seat, and a rim movably held in said seat.
4. A top roller for the purpose set forth having a metal boss, and a movable
rim, substantially as and for the purposes specified.
5. A top roller for worsted spinning and drawing frames having a flanged
periphery in which is freely seated a rim of material held in place by said flanges,
a metal boss being located in the center of the roller and secured to the metal
arbor by a set screw, substantially as described.
