Improvements in Top-rolls for Spinning Machines, Drawing Frames,
Mules, and the like.
We, LEON WILLIAM CAMPBELL, of Woonsocket, in the County of Providence,
State of Rhode Island, and MALCOLM CAMPBELL, of Beach Street, corner of
Lincoln Street, Boston, in the County of Suffolk and State of Massachusetts,
in the United States of America, Gentlemen, 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, the same letters designating the same parts or features,
as the case may be, wherever they occur.
Of the drawings,-
Figure 1 represents one embodiment of the invention, in which the saddles
are hung at the ends of the roll instead of at the middle portion thereof.
Figure 2 represents another embodiment of the invention.
Figure 3 represents a third form of the invention.
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 bored at its ends to form a socket a¹ for the reception of a spindle
which is thrust thereinto and held against displacement by frictional engagement
of its surface with the walls of the socket. This spindle b is provided with a
flange which abuts against the end of the roll and with a reduced portion b²
separated from the flange bl by a bearing cone 63 and a dust guard or flange b'.
The extremity of the reduced portion 62 of the spindle is threaded, as at b³,
to receive a bearing-cone c, formed on a nut c¹ which has a dust-guard or flange ²
said cone c being locked after adjustment by a screw abutting against the
end of the spindle. The bearing-cones 3 and c extend in opposite directions
inwardly.
A sleeve or stationary member d is placed around the end of the spindle and
is formed with cups did on its ends for the anti-friction balls which are
placed between them and the bearing cones c b³.
The saddles, which are not shown, but with which those skilled in the art to

page_text: - which this invention relates are familiar, are hung from the sleeves or stationary
members d d at the ends of the roll. When it is desired to remove a roll for the
insertion of a new one, or to allow of its being recovered or re-shod with leather,
the saddles are removed and the spindles are withdrawn from the sockets a¹,
without dislocating or displacing the anti-friction devices..
The roll shown in Figure 2 is quite similar in numerous respects to that which
we have just described, but it differs therefrom in details of construction, as will
be readily seen by examining the two figures.
b
The roll or rotary member a is provided with the socket a', as previously
described, and there is a spindle which is inserted in the socket, and which is
held therein by its frictional engagement with the walls of said socket. The outer
end 66 of the spindle b is somewhat enlarged, and on its extremity is a flange b²,
to form, as it were, a cup for anti-friction balls, as will be presently explained.
Between the inner and outer portions of the spindle, there is a screw-threaded
portion 68 on which are adjustably secured a bearing-cone 69 and a lock-nut 610.
A sleeve or stationary member is arranged on the outer end of the spindle,
being provided with a tapering socket dopposite the flange 7 and a ball-cup de
opposite the bearing-cone 6º. Anti-friction balls d', ds, are inserted respectively
between the flange 67 and the tapering wall of the socket do, and the cup do and
the bearing-cone 6º. Consequently, it will be seen that the main difference between
the devices illustrated in Figures 1 and 2 is, that in Figure 2 the bearing-cone at
the inner portion of the spindle is adjustable, and that in Figure 2, the spindle
is provided with a ball-cup at its outer end, instead of forming the ball-cup on
the sleeve.
For the purpose of closing the sleeve, in Figure 2, against the entrance of dust,
the outer end of said sleeve is exteriorly threaded to receive an externally threaded
cap e.
Next referring to Figure 3, it will be seen that the device illustrated thereby
bears a still closer resemblance to the one portrayed in Figure 1. On the
spindle b, which is inserted in the socket on the end of the roll a, is placed a
sleeve which has internal threads at its outer end whereby it can be screwed
on the threaded outer end of the said spindle. A screw f1 is inserted in the outer
end of the sleeve and abuts against the end of the spindle b so as to lock the sleeve
thereon after being adjusted. The sleeve is provided with a stationary bearing-
cone and a detachable bearing-cone f³, the sleeve or stationary member g
surrounding the sleeve f being formed with cups g g for the balls g³..
In all of the three figures which we have described, the top-roll or rotary
member a is supported or journaled at its ends, being provided with a socket to
receive inwardly extending spindles upon which are journaled sleeve or stationary
members from which the saddles depend; and in all of them, the bearing cones
are detachable, being locked after adjustment by suitable devices.
Having now particularly described and ascertained the nature of the said
.invention, and in what manner the same is to be performed, we declare that what
we claim is
1. A top roll comprising a rotary member, two stationary members, one
detachably connected to each end of said rotary member, said stationary members
being adapted to receive and support saddles, independently of each other, and
anti-friction devices inserted between said stationary members, and said rotary
member.
2. A top-roll comprising a rotary-member, an independent stationary member
detachably connected to each end of the rotary member, said stationary members
being adapted to support saddles independently of each other, and anti-friction
devices inserted between the stationary members and the rotary member, said
devices being constructed and arranged whereby they remain in place when the
rotary member is detached from the stationary members.
3. A top roll comprising a rotary member having a socket in each end, a

page_text: spindle inserted in each socket, stationary members into which the spindles
extend, and which are adapted to receive saddles, and anti-friction devices inserted
between said spindles and said stationary members.
4. A top roll comprising a rotary member having a socket in each end, a spindle
detachably inserted in each socket and frictionally held therein, stationary
members into which the spindles extend and anti-friction devices inserted between
said spindles and said stationary members.
5. A top roll comprising a rotary member, spindles connected to the ends of
said member, a stationary member or sleeve on each spindle and adapted to receive
and support a saddle, said spindles and sleeves being provided with bearing-cones
and cups, and anti-friction balls between said cones and cups.
