Office of the Commissioners of Patents on the 27th August 1881.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN RING-SPINNING MACHINES
OR FRAMES." A. communication from abroad by Stephen A. Jenks, of Central
Falls, Rhode Island, United States of America, Manufacturer.
My improvements are specially applicable to that class of ring spinning frames
which have two sets of rolls, and which are adapted to the production of "filling,"
for the reason that they embody means for variably speeding the drawing rolls, or
the delivery rolls, or both, for attaining uniformity in the size and twist of the
yarn notwithstanding the varying conditions incident to the operation of the
traverse or 'copping" motion, and the gradual increase in diameter of the wound
bobbins.
"
Heretofore in spinning frames of this class the rolls have been operatively
connected with the driving shaft of the machine by trains of high speed gearing,
or by two belts engaging respectively with two pulleys, each of which is geared to
one or more of the rolls in one of the sets of rolls, and a third pulley geared to
a portion of the rolls in both sets of rolls, the said two belts engaging with a
double faced pulley on the main shaft.
The objects of my improvements are to obviate the noise, wear and tear incident
to high speed gearing, and lessen the expense and annoyance incident to a
multiplicity of belts.
Instead of having a belt-pulley to each set of rolls and an additional pulley for

page_text: driving a portion of the rolls in both sets or equivalent trains of high speed
gearing, I employ two belt pulleys and connecting gearing for driving a portion
of the rolls in both sets, and one belt for communicating motion from the main
shaft to both of the said pulleys coupled with the desired capacity for effecting the
graduated rotation of a certain roll or rolls in each set of rolls.
My Invention is illustrated in the accompanying Drawing, in which
Figure 1 represents in end elevation as much of a ring spinning frame as is
necessary to illustrate the application of the said Invention thereto.
Figure 2 is a plan or top view, and
Figure 3 is a side elevation of the same.
The end plate A of the frame is as usual cast in one piece, and provided with
suitable bearings, pillars, ears, and studs for mounting the rolls and the requisite
shafting pinions and other parts. The driving shaft B is located as heretofore and
carries at its outer end the plain pulley C.
It will be understood that in some cases the front or delivery rolls only in each
set of rolls is variably driven; and in the other cases the front rolls are regularly
driven and the rear rolls driven variably, and it has also been proposed to variably
drive all of the rolls. My improvements are applicable in either of the cases
indicated. As shown in the Drawing for the purposes of illustration the front or
delivery rolls a in both of the two sets are variably driven.
The conical belt pulley D is mounted upon a stud and is directly geared to the
front roll of the right hand set of rolls (Figure 1) by the pinion b connected with
the said pulley and the gear wheel c on the front roll shaft; the gear wheel
d on the front roll shaft of the left hand set is operated by the gear wheel c
through the intermediate gear wheels c¹ and d'.
The plain belt pulley E is also mounted upon a stud and has a gear wheel e
connected therewith; this gear wheel meshes with the gear wheelf on a shaft f¹,
which carries a small gear wheel g meshing with the gear wheel . This gear
wheel meshes with the gear wheel i, and these wheels are respectively geared to
and drive the middle and rear rolls of the two sets of rolls through gearing at each
side of the frame composed of the gear wheel k, and the pinion 7 connected
therewith (mounted on a stud) and meshing with a gear wheel m on the rear roll
shaft; the latter drives the middle roll by means of the usual gearing at the
opposite end of the machine. It will be seen that if the position of the conical
pulley D and the plain pulley E be altered the front rolls of both sets will be
driven with uniformity, and the rear rolls in both sets will be variably driven.
This arrangement of two belt pulleys so geared that each operates a separate portion
of each set of rolls constitutes a novel and important feature, even if a separate
belt be employed for operatively connecting each of the said pulleys with the main
shaft, and although I prefer one belt applied as shown, this latter arrangement is
mainly dependent upon the novel feature above referred to.
The idle or loose pulley F is located beneath the pulley C on the main shaft, and is
preferably conical in form to correspond with the conical pulley D. The belt G is
continuous and passes around and beneath the pulley C, around and above the
pulleys D and E, and thence and around and beneath the conical, idle, or loose
pulley F. The maintaining of the belt at a proper tension is of great importance
by reason of its length and its numerous turns, and I therefore provide means for
tightening the saine by mounting the said idle pulley in vertically movable bearings,
and by employing means for pressing or drawing the said pulley downward against
the lifting tendency of the belt. A screw with a hand wheel for forcing the
pulley downward may be employed, but I prefer to render it automatic in its
operation by mounting the said loose pulley upon the outer end of the lever H and
providing the latter with the weight n. The automatic shipper I which controls
the belt G with relation to its position on the conical pulley D is arranged in the
ordinary manner.
It will be readily understood that if it is desired to variably drive all of the rolls
in each set, both of the upper pulleys may be conical; but in order to efficiently

page_text: control the belt in its relations to the pulley E a shipper-fork would be provided
as indicated in dotted lines at I, which fork could be connected with the
shipper-rod on which the shipper fork I is mounted, and if the pulley E is conical;
and the pulley D plain it would be advisable to locate the shipper-fork I at the
point indicated at I¹.
The loose pulley F being mounted upon a weighted lever as shewn need not
necessarily be conical, for the reason that if the said loose pulley has a straight
face the slack in the belt incident to its varying position on the conical pulley D
would be readily disposed of.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
First. In a ring spinning frame having two sets of variably driven rolls, the
combination with the said rolls of two belt pulleys geared respectively with one
or more rolls in each set of the rolls, substantially as above described.
Second. In a ring spinning frame having two sets of variably driven rolls, the
combination with a pulley on the main shaft of two pulleys (one or both conical)
respectively geared with one or more rolls in each set of rolls, and a loose pulley,
whereby one belt may be relied upon for engaging with all of the pulleys for
driving the rolls, substantially as above set forth.
Third. In a ring spinning frame having two sets of variably driven rolls, the
combination with a pulley on the main shaft of two pulleys (one or both conical)
respectively geared with one or more rolls in each set of rolls, and a loose pulley
mounted upon a weighted lever, whereby one belt may be relied upon for engaging
with all of the pulleys for driving the rolls and maintained at an even tension,
substantially as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty seventh day of August, in the year of our Lord
One thousand eight hundred and eighty one.
W. KUB. LAKE.
