Improvements in Machines for Winding Yarn.
I, SIMEON BERARD, of Fall River, in the County of Bristol and State of
Massachusetts, United States of America, Gentleman, 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:
My invention relates to winding machines and its object is to provide means
for automatically reciprocating or moving the ring rail up and down so as to
insure the yarn being wound evenly on the cop or bobbin; also to provide an
improved cop forming cam for automatically causing the bobbins to be tapered
or beveled at the ends, and a stop motion cam for stopping the machine when
the bobbins are full.
The invention consists in the novel construction and combination of parts
hereinafter fully described and claimed.
In the accompanying drawing,
Figure 1, is a side elevation of a winding machine constructed in accordance
with my invention.
Figure 2, is a front elevation of the same.
Figure 3, is a plan view on an enlarged scale of the cam frame, showing the
filling, the cop forming and building and stop motion cams and other parts.
Figure 4, is a detail perspective view of the building and stop motion cams.
Figure 5, is a similar view of the cam for forming the cop.
Figure 6, is a longitudinal sectional view of the cam shaft and cams.

bobbins are full.
.
Figure 8, is a detail elevation of the pawl and ratchet mechanism.
Figure 9 is a sectional elevation, showing the cop produced.
In the said drawing, the reference numeral 1 designates the machine frame,
and 2 the vertically movable ring rail supported by a rod 3 passing through
a hole in the horizontal spindle rail 4. The lower end of this rod is pivotally
connected with a lever hereafter described for vertically reciprocating the ring
rail. The numeral 5 designates the spindles journaled to the rails 4 and provided
with pulleys 6 by which they are rotated. The numeral 7 designates the bobbins
which are movable with the ring rail. The parts so far described may be of
any ordinary or suitable construction.
The numeral 8 designates the cam frame, near the bottom of the machine
at one end, provided with a horizontal shaft 9 provided at one end with a worm
wheel 10, with which engages a worm gear 12 at the lower end of a vertical
shaft 13 provided at its upper end with a beveled pinion 14 which is driven
by a corresponding pinion 15 on a horizontal shaft 16. This shaft is provided
with a cog wheel 17 which is driven by a driving shaft 19 through the medium
of a pinion 20 and intermediate gears 21 and 23. Mounted on said shaft 19
is a fast pulley 24 and a loose pulley 25. The numeral 26 designates a laterally
movable shifting device for shifting the belt, not shown, from one pulley to
the other.

page_text: The shaft 9 is formed with a horizontal groove 27 in which is located a laterally
movable key 28 provided at one end with a lug 29 and at the other end with an
enlarged portion 30 projecting beyond the periphery of the shaft and also pro-
vided with a lug 31. Mounted on said shaft is a cam 32 which is rotatable with
and also laterally movable on said shaft, by means of the enlarged portion of
the key engaging with a groove therein. This cam I term the filling cam, as
by its action, the ring rail is vertically reciprocated to ensure the even winding
of the yarn. Also mounted on said shaft and rotatable therewith and laterally
slidable thereon is a heart-shaped tapering cam 34, which I term the cop forming
cam, by means of which the bevel or taper is given to the ends of the bobbin.
The enlarged portion of said slidable key also engages with a groove in said
cam and the lug 31 bears against the outer end of the cam. The numeral 36
designates a pin secured to a horizontally movable feed slide 37 also provided
with a pin 38. These pins project through a slot 39 in one of the sides of said
cam frame and serve as guides for the slide. The said pin 38 projects beyond
the outer side of the slide and is adapted to strike and operate a vertical lever 40,
which is pivoted to one end of a worm shaft 44. This lever is provided with a
pawl 42 which engages with a ratchet wheel 43 on the intermittently rotating
shaft 44 so that as said slide is moved forward by said pin, it will engage with
and rotate the ratchet. Secured to said shaft is a worm 45 which engages with
a corresponding worm wheel 46 on a building and stop motion cam 47, hereafter
described, loosely mounted on the shaft 9, and the outer end of which engages
with the lug 29 of the sliding key. Connected with said slide 37 is one end of a
chain 48 which passes over a pulley 49 and at its opposite end is provided with a
hook 50 which removably engages with an eye or loop on a rock shaft 51. This
chain when disconnected from said shaft is adapted to be connected with a
weight 52.
The cam face of the stop motion cam is in the form of a spiral and has a
straight longitudinal edge 53. This cam engages with a dog 54 secured to the
cam frame so that as the cam is intermittently rotated by the worm wheel and
shaft, operated by the lever, pawl, ratchet and slide it will be moved laterally
forward on the shaft 9. When the said stop motion cam reaches the end of its
forward motion the dog 54 will come into coincidence with the straight edge 53
of the cam and allow the latter to be moved back by a pin 56 thereon engaging
with a rotatable shaft 57 formed with a spiral groove 58. This shaft is driven
by the cog-wheel 59 secured thereto which meshes with a cog wheel 60 on the
shaft 9.
The rock shaft 51 is also provided with an eye or loop 61 with which is
removably connected a hook (2 on one end of a chain 63. This chain extends
over a pulley 64 and its opposite end is connected with a laterally movable rod
which works in a sleeve 65 secured to the cam frame. The free end of this rod
is provided with a roller 67 which engages with the cop forming cam. Secured
to said rock shaft 51 is a chain 68 which is connected with a segment head at
one end of a lever 69, the other end of which is connected with rod 3 so that
as said rock shaft is oscillated the ring rail will be vertically reciprocated.
Secured to said stop motion cam is a pin 70 which is adapted to strike against
the lower end of an elbow lever 71, the short arm 72 of which engages with a
shoulder 73 on one end of the horizontally movable rod 74 which works in bear-
ings 75. This rod is connected by a bracket 76 to the belt shifter 26 and is
provided with a lug 78 between which and one of said bearings is interposed a
coiled spring 79 which shoots the belt shifter when the arm 72 is disengaged
from the shoulder 73.
At the beginning of the operation, the cams will be at the right of the cam
frame with the dog 54 engaging with the inner end of the spiral face of the
stop motion cam and the chain connected with the slide operated by the filling
cam disconnected from the rock shaft 51 and the chain connected with the roller
which is actuated by the cop forming cam secured to said shaft. The machine is

page_text: now set in motion by shifting the belt from the loose to the fast pulley, the short
arm of the lever 71 engaging with the shoulder 73, of the rod 74, so as to hold
the belt shifter and keep the belt on the fast pulley. The shaft 9 will now be
rotated by the worm wheel and connections from the driving shaft. As the
said shaft rotates, the filling cam is correspondingly rotated which acting on
the pin of the slide 37, will cause the latter to be reciprocated back and forth,
and the worm shaft and stop motion cam will be rotated through the medium of
the ratchet 43, pawl 42 and lever 40. The slide makes one reciprocation for each
revolution of the filling cam, pushing the slide towards the left during one half
of the revolution and turning the shaft 44, and during the other half of the
revolution allowing the slide to be pulled in the opposite direction by the
weight 52, the pawl 42 riding over the teeth of ratchet 40. This reciprocation
of the slide is caused by the peculiar formation of the filling cam and the ratchet
is moved one tooth or step at each reciprocation. As the stop motion cam is thus
intermittently rotated, the dog 54 engages with the front end of the spiral cam
face thereof, causing said cam and the filling and cop forming cams to be moved
forward or towards the left end of the machine. During this operation, the
roller 67 rides upon the cam 34 which by its peculiar formation will cause the
ring rail through its connections to be vertically reciprocated, and by the shape
of said cam the stroke of the ring rail will be gradually shortened, so that the
ends of the bobbin will be tapered. After said ends are thus tapered, the
chain 63 is disconnected from the rock shaft 51 and the weight 52 detached from
the chain 48 and the latter connected with the rock shaft. The ring rail will
now be moved up and down through the medium of the filling cam and the
slide 37. The filling operation is continued until the bobbins are full, when
the stop cam will have made a complete revolution. The said cam will now ride
off of the dog 54 and the pin 50 will engage with the spiral groove in the rotating
shaft 57, whereby said stop cam, filling cam and cop forming cam will be returned
to the right hand end of the machine. The sliding key and the lugs on the ends
thereof cause the filling cam and cam 34 to move with the stop cam. As said
stop cam reaches its first position, the pin 70 thereof will strike and actuate the
elbow lever 71, releasing the helt shifter so that the belt will be shifted from
the fast to the loose pulley and the machine stopped. During the latter part
of the above operation, the cop forming cam will perform no function, the filling
cam causing the yarn to be wound evenly upon the bobbin, the cop forming cam
being only employed to cause the taper at the ends of the bobbin at the beginning
of the operation. The cop forming cam may be disconnected from the rock shaft
which reciprocates the ring rail at any stage of the operation. For winding a
bobbin without tapered ends, the cop forming cam is not used but is disconnected
from the rock shaft.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a winding machine, the combination with the vertically reciprocating
ring rail, of the rotatable and laterally movable filling in cam, and means for
