for Use in the Shuttles of Sewing Machines.
I HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents
Southampton Buildings in the County of Middlesex, (a communication from Maro
Virgil Palmer, machinist, a citizen of the United States of America and resident of
Willimantic, in the county of Windham and state of Connecticut) do hereby declare
the nature of my said invention for IMPROVEMENTS IN MACHINES FOR WINDING
SHUTTLE COPS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The object of my invention is to provide a machine by means of which a peculiar
cop may be wound compactly and evenly to adapt it for use in the shuttle of a sewing
machine. To this end my improvement consists in the combination of devices whereby
the cop is wound between the faces of rollers running at substantially the same
velocity; it further consists in the combination of the spring seated bearings that
support the pin on which the cop is wound under pressure between the rollers; it
further consists in the stop device, in the adjusting device that determines the
diameter of the cop, in the combination of devices for pulling out the pin; and in
further details of the parts and their combination as more particularly hereinafter
described and pointed out in the claims.
Referring to the drawings:
Figure 1 is a front view of one of my improved machines for winding shuttle cops.
Figure 2 is a top view of the same.
Figure 3 is a detail top view of the trip device and of the adjusting device.
Figure 4 is a view in vertical cross-section of the device on plane denoted by
line x
x of Fig. 1.
Figure 5 is a detail view in vertical section of the machine on the same plane
showing the parts in position after tripping the upper roller.
Figure 6 is a detail top view of the device for pulling the pin out of the cop.
In the accompanying drawings the letter A denotes the frame or bed of the inachine;
b and b denote standards; c the main shaft extending across the machine and
supported in bearings in the standards; da pulley to receive a belt by means of which
the machine may be driven from any convenient countershaft or source of power.

page_text: Fast to this main shaft c is a cam block e having a cam-groove e¹ into which projects
a pin borne on a block f' adjustably secured to the sliding rod fas by means of a
clamp screw f³.
On this reciprocating rod are supported the guides 9 through which the thread
passes while being wound to form a cop. The device just described is the ordinary
traverse device common to other winding machines and the guides are also of well-
known construction.
The thread passes to the guides through the tension device on the upper end of
the arm fast to the frame of the machine. On the main shaft c there is also fast a
cog-wheel c meshing into a larger cog-wheel c¹ that is supported on an arbor i held
in the standards b, and extending across the frame parallel to the main shaft. The
wheel turns freely on this arbor and meshes into a gear-wheel e3 that is fast to the
shaft of the roller that is supported in bearings on the outer end of the frame K.
This roller frame is supported by and swings freely on the arbor i holding the roll ¹
at the lower limit of its play directly over the roll k² that is fast to the same shaft as
the cog-wheel cl, and is driven by it. The arrangement of cog-wheels just described is
such that the adjacent faces of the two rolls k¹, 2 travel in opposite directions. The
front ends of the arms of the spring 1 that is supported on the standard on the back
of the frame lie between the planes of the upper and lower rollers k¹, k², and within
them are formed the bearings 2 for a small pin m on which the cop n is wound, and
this pin is held in its bearings directly between the surfaces of the rolls k', k². In
Fig. 5 I have shown the rolls and pin bearings in the positions they are caused to
assume when it is desired to remove a wound cop or to place a pin within the
bearings; the upper roll being shown held above and out of contact with the cop
or pin, which latter is in turn held out of contact with the roll 2, these parts occupying
the relative positions shown. After removing a wound cop and placing a bare pin in
the bearings by pulling forward upon the handle g the frame K is so moved as to
hold it with a yielding pressure upon the lower roll and between the surfaces of the
two rolls.
The upper roll is thrust downward with a yielding pressure upon this pin by
means of a spring that is coiled about the hub of the arm o that is also supported
on the arbor i. One end or loop of this spring supports an adjusting screw k³, by
means of which the degree of pressure of the spring upon the frame K may be
adjusted while another loop of the spring passes around the back of the arm o in such
manner that the tension of the spring tends to rotate the frame and the arm in opposite
directions on the arbor i.
The lower end of this arm o has a slot o', through which passes a pin o², by means
of which it is connected to a slide o³, moving in guideways across the frame A. In a
socket a¹ in the upper part of the frame seated a spring o*, with one end fast to the
front part of the frame and the other to a. hook fast to the slide, the function of the
spring being to pull the slide forward.
This slide forms part of the trip device P the function of which is to lift the upper
roller out of contact with the cop n as soon as it has reached the predetermined
diameter and this lifting of the upper roller allows the spring to lift the cop out of
contact also with the lower roller and stops the further winding of any thread upon
the cop.
The bell crank lever p (see Figs. 4 and 5) is pivotally connected to a stand on the
front of the frame with one arm pl extending toward the slide o³, and bearing a
roller p² adapted to rest against the shoulder or angle os on the front of the slide. The
upper arm of the bell crank lever p is connected by means of the rod p³ with the dog p*
that is pivoted to the upper part of the slide base and projects upward with its outer
end arranged to come into contact with the arm ko that projects downward from the hub
of the frame K. By means of the adjusting screw p the point at which the upper
end of the dog and the lower end of the arm k slip past each other
may be
determined.
In order to return the frame K and the roller k¹ to the lower limit of its play the
handle g is pivotally supported on the arbor i and is provided with a sidewise extending

page_text: arm q', that by contact with the arm of that projects from the hub of the arm o causes,
when this handle is pulled forward, the arm to be pulled backward and the tension of
the spring forces the frame downward. Another arm g' projecting from the hub of
the handle serves, by contact with a post or standard q³ fast to the frame, to limit the
backward play of the handle.
The operation of my device is as follows: a pin m having been placed in the
bearings in the front end of the spring arm the roller is, by the means already
described brought down upon it and held there by the pressure determined by the
spring, the pin being held between the adjacent surfaces of the rollers k¹ and k³, the
end of the thread is caught on the pin and by the rotation of the main shaft c is wound
upon it, the traverse motion of the thread being imparted by the reciprocating motion
of the slide rod, and under pressure between the two rolls so that the thread is massed
evenly and closely upon the pin.
This winding of the thread upon the pin continues until the cop has reached the
desired diameter and the end of the arm k forces the end of the dog over, tilting the
lever and lifting the roller p² out of contact with the shoulder o³ on the slide.
The slide is then pulled sharply forward by means of the spring of and the upper
roller lifted out of contact with the cop and further winding of thread stopped.
When the slide o³ is thus pulled forward by the spring o, this movement of the
slide causes the connected arm o to swing forward, turning on its hub that is pivoted
on the arbori by this movement of the arın o into the position as shown in Figure 5,
a projection o, on the front side of the hub, that underlies a part of the frame K, is
brought into contact with the frame before the forward movement of the arm ceases,
and by the continued movement of the arm lifts the frame. This projection on the front
part of the hub of the arm is shown in Figure 4 of the drawings, and, in dotted outline,
in contact with a part of the frame in Figure 5 directly below the adjusting screw k³.
The thread is then cut close to the cop and the latter removed from the spring
supported bearings. The pin m upon which the cop is wound still remains in it and
to pull it out I make use of the pull out device R shown in Fig. 6 of the drawings.
A cog-wheel is borne on a shaft r¹ mounted in a standard fast to the frame in
such position that the wheel meshes with and is driven by the large gear-wheel c². A
crank arm on the shaft is connected by a pitman to the lever that lies cross-wise
of the pitman and is supported at one end in a groove in the stand s, and the other is
pivoted to the front end of the lever that lies about parallel to the path of the pitman.
On the front end of the lever a jaw is located opposite to the bent end of the
lever, which end forms the complementary jaw, and between these jaws the end
of the pin m is grasped at the instant the pitman begins its return movement, its pull
on the lever closing the jaws, while the push of the pitman opens the jaws.
One end of the cop is held against the end of the rest t with the end of the pin
projecting toward the jaws and adapted to be grasped by them as described.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, as communicated
