WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN FEED-REGULATING APPARATUS
FOR DRAWING, TWISTING, OR SPINNING MACHINERY." A communication from abroad
by Joseph C. Todd, of Paterson, New Jersey, United States of America.
This Invention relates to that class of devices which are applied to drawing,
twisting, or spinning machinery, for automatically regulating the size of the sliver
yarn or roving.
My improvements consist in actuating the feeding device, whether a chain-feed
apron or other appliance be used therefor, by a friction-driver adapted to reduce
the size of the yarn or sliver when produced by too rapid a feed, and to enlarge it
when the feed delivers the material too slowly.
I am aware that a ratchet-feed operated by two pawls has been connected with
the condensing rolls through which the sliver passes; but such a device produces
but a single and abrupt change in the speed of the feeding device, while my
improved device is capable of graduating the speed of the feed with the utmost
nicety, and also of stopping it entirely if the feed is excessive.
The construction and arrangement of my friction driver will be readily under-
stood by reference to the accompanying Drawings, in which,-
Figure 1 is a side elevation of a spinning jenny with a portion of the framing
removed, and with my improvements attached to the same.
Figure 2 is a transverse vertical section on the line x, x, Figure 1.
Figure 3 is a plan of the regulating roller and its tipping frame.
Figure 4 is a plan of the driving shaft and adjacent parts; and
Figure 5 is an enlarged view of the friction driver governed by a nipper.
Figure 6 is a side elevation of a slightly modified arrangement of a spinning
jenny with my improvements attached to the same.

page_text: A, A, are the side bars of the frame; B, B, the posts; and C, C, the cross ties;
D is the driving shaft of the machine; and E, E, are the fast and loose pulleys on
the same; F is the pulley for driving the calender-rolls; L and G is the pulley for
operating the friction-driver; H is the feeding apron, which is driven by the shaft I
and feeds the slivers through the conductor K to the calender-rolls L.
From the calender-rolls L the thread t passes through the hole M in the flyer O
to the bobbin N in the usual manner.
A drum U is secured upon the shaft R between the lower side bars of the frame,
and connected by gearing S to the driving shaft D. This drum serves to operate
the bobbin N through the belt V and pulley W in the usual manner.
The shaft R
also carries a pulley T, which drives the flyer O by means of a belt applied to the
pulley P, which is secured to the flyer near the standard Q¹. The standard Q
supports the outer end of the bobbin-shaſt, and the mode of operating these parts
being well understood no further reference to them is necessary.
My Invention relates to the parts employed in transmitting the motion from the
main shaft D to the feed-shaft I, and is carried into practice as follows:-
Between the driving and feed shafts is placed an upright shaft a provided with
a disc band pulley c, the said disc serving to receive the motion through my
improved friction-driver and the pulley c to transmit it to the feed-shaft I.
The shaft a being vertical and the feed-shafts I revolving horizontally, an inter-
mediate shaft d is provided to change the direction of the motion by means of a
twist belt e; or instead of the said pulleys and belts I in some cases transmit
motion from the aforesaid vertical shaft a to the pulley d by means of gear wheels,
as shewn in Figure 6, or other suitable gearing may be employed.
The disc b receives its motion from a friction-driver f, which is secured to the
shaft or arbor hung in a tipping or swing-frame j. This arbor is provided with
a pulley g, as shewn in Figures 1, 2, and 3, and around this pulley is passed a cord
or belt from the pulley G on the main or driving shaft D, and the arbor and
driver fare thus revolved at a uniform rate of speed.
The roller is shewn as of convex outline at its point of contact with the disc,
underneath which it is supported by the frame j, the arbor i being radial to the
shaft a.
From this arrangement it will be seen that if the frame j be tipped out of a
horizontal position the point of contact between the driver and disc will be changed,
and the motion imparted to the disc will be varied in its rate of speed.
The disc b and its vertical shaft a are so constructed that the weight of the same
constantly presses the disc against the convex surface of the driving roller f, and
the driver being made of leather, rubber, or other suitable material, the motion is
transmitted at the desired rate of speed to the feed-shaft I.
To tip the frame j automatically a connection is required to the sliver s or
thread t, so that as the latter deviates from the proper or standard size the feed may
be varied to correct such deviation.
This object may be attained by means of a connection to the calender rolls
through which the sliver passes, or by providing a nipper, as shewn in Figure 5, to
operate the frame j as the sliver varies in size.
In Figures 12 and 3 the frame is shewn as provided with a crank o connected
to one of its trunnions , and a rod is attached to this crank to receive the
notion from the upper calender-roll L.
The roll L is supported by journals in two levers m, the short arms of which are
pivotted close to the roll, while the longer arms are jointed to the rod n, which thus
receives a much greater movement than that produced in the roll L by the in-
equality of the sliver. So long as the sliver passes under the roll I uniformly, the
roll and its supporting lever m will remain unmoved, but any variation in the size
of the sliver will produce a movement in the lever m and tip the frame j, to which
it is connected by the rod n and crank o. The crank is so attached to the frame j
that an increase in the mass of the sliver throws the outer end of the roller f in

page_text: contact with the disc ₺ near its periphery, and thus reduces the speed of the feed
until the sliver regains its proper size.
Should the sliver elevate the roll L to an excessive extent the feed will be entirely
arrested, as a loose pulley w is provided on the arbor ȧ to come in contact with the
disc. When the extreme outer end of the driving roller f fails to reduce the speed
of the feed sufficiently the loose pulley being placed on the arbor near the rim of
the disc and supporting it without transmitting any motion to the feed when the
frame j is sufficiently tipped.
In Figure 5 the frame shewn controlled by a nipper v, through which the
sliver passes to the flyer, and by which the variations in the sliver are caused to
move the frame; as desired. A lever u is hinged to the posts of the frame by the
fulcrum u, so that its upper end carries the nipper v and its lower end actuates a
rod connected to the crank o.
is
The lever being vertical, the crank o is secured to the trunnion in a vertical
position, and the movements of the lever u operate the frame j in the same manner
as the levers m. When thus arranged the arbor i would be parallel to the side
frames A, and would require to be driven by some other means than the pulley g,
as by a universal joint connected in any desired manner with the main shaft D.
From the above descriptions it will be seen that the operation of the friction-
driver is the same, however it may be connected to the sliver, so as to act auto-
matically; and I do not therefore limit myself to the use of the means above.
described for making such connection.
q
Both the nipper and the calender-rolls are intended to be adjustable, and
arranged to pass a larger or smaller sliver or thread, as may be desired; and tho
connections between them and the frame j may be made adjustable for the same
purpose in any desired manner.
In Figure 5 I have shewn a different method of driving the roller f to that
shewn in the other Figures, and do not consider that it is material to my Invention
how the roller or driver f receives a uniform rate of motion; nor that the said
roller should be the driving agent, as the uniform rate of motion might be imparted
first to the disc b, and the variable movement transmitted from the roller f to the
feed-shaft I if preferred. .In Figure 5 the roller f is shewn driven by a universal
coupling q, attached at one end to the arbor i, and intended to be connected at
the other to the shaft R, which with the arbor i is placed parallel to the side frames A.
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 under-
stood that I claim,-
First. In a machine for drawing or twisting fibrous materials the combination of
the following instrumentalities for automatically regulating the size of the sliver
yarn or roving, namely, a disc and roller operating together by friction, as herein
set forth, and connected to the calender-rolls or nipper for altering the relative
positions of the disc and roller, and thereby modifying their relative speeds,
substantially as herein described.
Second. In combination with the disc b and friction-roller hung on the frame j
the loose pulley w arranged upon the arbor to prevent the transmission of motion
when brought in contact with the disc for the purpose herein set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Fifteenth day of May, in the year of our Lord One
thousand eight hundred and seventy nine.
