Improvements in Top-rolls for use in connection with Spinning
Machinery.
We, LEON WILLIAM CAMPBELL, of Woonsocket, Rhode Island, Salesman, and
MALCOLM CAMPBELL, of 28, Utica Street, Boston, Massachusetts, Manager, both
in the United States of America, 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 has relation to top-rolls for spinning machines, fly-frames,
drawing-frames, and the like, and has for its object to provide certain improve-
ments therein whereby they may revolve with greater rapidity and with less
friction than heretofore, and whereby they will not require the employment of
oil or other lubricant, which, as is well known, is liable to injure the leather
coverings of the rolls, and spoil the yarn, and will consequently last longer
and cheapen the cost of production of the yarn or thread.
To these ends, the invention consists of a top-roll embodying certain features
of construction and relative arrangement of parts, all as fully illustrated upon the
accompanying drawings, now to be described in detail, and finally pointed out
in the claims hereto appended.
Reference is to be had to the accompanying drawings, and to the letters and
figures marked thereon, forming a part of this specification, the same letters
designating the same parts or features, as the case may be, wherever they
occur.
Of the drawings:-
Figure 1 represents an embodiment of the invention in which there is a shell
detachably rotatable on anti-friction balls supported by a stationary spindle.
Figure 2 represents another form of the invention in which anti-friction rolls
are employed in lieu of balls.
Figure 3 represents a transverse section through the end of the roll shown
in Figure 2.
Figure 4 shows one of the collars or roll-retainers detached.
Figure 5 represents a modified form of collar or roll retainer.
Figure 6 represents a cross section through the end of the roll and shows the
clip for holding the shell against axial movement.
Referring to the drawings,a indicates a top-roll or rotary member which is
cylindrical as shown, and which may receive a suitable covering of leather or
other material. It is journaled upon the end of a stationary member or spindle
in anti-friction bearings supported by the latter. The stationary member or
spindle b, of which one end is shown, is adapted to receive and support the saddle
and is provided with a reduced portion b₁ and a shoulder 62, and placed upon the
reduced portion b¹ are three collars or sleeves c, c¹ and c³, the latter being pro-
vided with a hub 3 which is internally threaded, whereby it is screwed upon the

page_text: threaded end of the spindle and is held in adjustment by a screw cabutting
against the end of the spindle, as shown. The sleeve or collar c¹ is provided at
its ends with grooves which are diametrically opposite grooves cc in
the collars c respectively, and in the said grooves are placed anti-friction
balls dd. Portions of said balls project beyond the periphery of the said collars
to receive the shell or rotary member a, which, as previously stated, is shod
with leather. To prevent the shell from slipping endwise or axially, it and the
collar or sleeve care provided with diametrically opposite grooves adapted to
receive a spring wire a¹, one end of which is inserted in the collar c¹.
ing to this arrangement, the shell or roll rotates on the anti-friction balls d,
being adapted to be removed whenever desired, by drawing upon it with more or
less force, so as to press the wire a down into the groove in the collar c¹.
Accord-
In Figure 2, the shell a is journaled upon rollers e having tapering ends e¹,
projecting into conical sockets in the collars e³, splined upon the reduced
end b of the spindle or stationary bearing b. One of the collars e³ bears against
the shoulder 2 while the other one is adjusted by the lock-nuts et e, screwed
upon the threaded ends of the spindle. The shell is held against accidental
movement by the spring wire a¹, one end of which is fastened to one of the
collars . Instead of inserting the tapering ends of the rolls in tapering sockets
in the supporting collars, we may form said collars with annular V-shaped
grooves, as shown in Figure 5.
From the foregoing description, it will be apparent that the roll or rotary
member is freely detachable from the stationary member, without disturbing
the relations of the anti-friction devices, and that its interior is cylindrical,
except for the annular groove to receive the fastener a¹. The stationary member
receives and supports the collars which maintain the anti-friction devices in
position, and one of the collars is adjustable toward and from the other to com-
pensate for wear. The shell directly engages the anti-friction devices.
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:-
1. A top-roll embodying a rotary member, a stationary member adapted to
support the saddle, a plurality of anti-friction devices inserted between said
members, and each having its periphery engaging and assisting in supporting
said rotary member, and means whereby said shell may be detached from said
stationary member without removing or displacing said anti-friction devices.
2. A top-roll embodying a rotary leather-shod sleeve or shell, a stationary
spindle adapted to receive and support a saddle, said sleeve or shell being detach-
able from the spindle, anti-friction devices inserted between said shell and
spindle, and non-rotary means independent of said shell supported by said
pindle for maintaining the anti-friction devices in place, whereby the removal
of the shell does not cause the displacement of the said anti-friction devices.
3. A top-roll comprising a stationary member adapted to support the saddle,
collars on said stationary member, a plurality of anti-friction devices supported
by the collars, a rotary member supported directly upon and engaging the
peripheries of all of said anti-friction devices, said rotary member being movable
axially, and means for detachably holding said rotary member against axial
movement.
4. A top-roll comprising a stationary member, adapted to receive and support
a saddle, non-rotary collars on said stationary member, anti-friction rollers held
in operative position by said collars, a rotary member or shell supported directly
upon and rotatable on said rollers, and means for detachably holding said shell
against longitudinal or axial movement relatively to said rolls.
5. A top-roll comprising a stationary member adapted to receive and support
a saddle, collars on said stationary member, anti-friction bearings supported and
held in operative position by said collars, the peripheries of said anti-friction

page_text: devices projecting axially beyond said collars, a rotary sleeve having a cylin-
drical interior, and supported directly by said devices, and means for detachably
holding said sleeve against axial movement.
