Specification Accepted, 20th July, 1888
I, HERBERT TYLER BARDWELL of Springfield, County of Hampden and State of
Massachusetts, United States of America, mechanical engineer 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 relates to improvements in spinning mules, the object being to pro-
vide an improved machine of this class capable of vertical instead of horizontal
operation, whereby the machine requires much less floor-space for its operation than
do other mule-spinners heretofore made, besides possessing other advantages herein-
after set forth, and the invention consists in the peculiar construction and arrange-
ment of the machine, all as hereinafter fully described and pointed out in the claims.

The herein described Mule-Spinner consists, generally, of a vertical frame, as shown
in Figure 3, and of end, and intermediate transverse supporting standards or frame-
posts, 2, 2a, 2b, and 2, and 3, 3ª, 3, and 3º, said vertical frame extending above
said standards and secured thereto, and consisting of end-posts, 461 and 461, and
intermediate posts, a, four in number, more or less, as the length of the machine may
require. The said posts are properly tied and supported by suitable diagonal braces
as shown in Figure 3. The feet or lower ends of said standards are suitably tied
together by a longitudinal angle-iron, 4, either double or single, as shown in
Figures 1, 2, 3 and 5, which is bolted to the front and rear edges of the said
standards.
The upper ends of said posts are tied together by a longitudinal angle-iron, 296,
on opposite sides thereof (see Figures 1, 3, 41 and 42,) a box-bracket, b, being fixed
between said angle-irons on the opposite sides of the upper ends of each of said
posts, 461, 461, and a. The employment of said box-brackets at the upper ends of
the posts, 369 and 277, near the center of the machine (see Figure 3, being obviated
by placing on the upper central part of the frame an inverted U-shaped iron
girder, 297, the ends of which extend beyond, and are fixed to the ends of said
posts, 369 and 277, as shown, and said angle irons, 296, are secured on the opposite
sides of said girder, the latter being built into said central part of the frame in
order to impart to it the requisite strength and rigidity to sustain the weight of the
carriage and its counter-balancing weight, 500, (see Figure 1).
The above-referred-to carriage constitutes that part of the mule-spinner on which
are carried the roving spools, the rollers on which they lie and turn, the delivery
rollers between which the rovings pass to the spindles, and the mechanism which
imparts the proper motion to said rollers and other operative parts of the machine,
as below described.
Said carriage consists of several pairs of suitable metal plates, one thereof, 463,
being shown in side view in Figure 4, the plate, e, which, with the latter makes said
pair, heing secured opposite the rear side of plate, 463, by the longitudinal angle-
irons, 308 and 324, (see Figures 1, 3, 4, 5,) which angle-irons extend the whole
length of the carriage on opposite edges of said plates and to the latter, as shown, said
angle-irons are bolted. Each pair of said carriage-plates is indicated in Figure 3, at, d.
In Figure 44, is shown a top-plan-view of one of said pairs of plates together with
parts of said angle-irons which are bolted thereto.
The plates, 463 and e, are provided with projecting webs on their inner opposite
sides which serve to hold the plates a certain distance apart, as shown in Figure 44,
to provide a central opening between them in the direction from the lower to their
upper edges through which the posts, 461, 461", and a, pass, and between said plates
opposite the sides of said post-passage are hung friction rollers, o, shown in Figure 44,
and in dotted lines in Figure 4. The peripheries of said rolls, o, are grooved to engage
with each edge of said post, and thereby the plates are guided without friction while
the carriage of which they are part, is moved vertically on said posts. Between those
parts of said plates which project beyond the angle-irons, 324, are provided perforated
abutting webs, f, which serve as a base on which to bolt the foot of an arm, 316, in the
upper end of which is a set-screw, as shown in Figure 4.
On the front and rear edge of the aforesaid plate, e, is an arın, g, having a bearing
in its upper end to receive the end of the shaft of the roving-spools hereinafter
described, when said spools are lifted off from the drums beneath them on which they
lie when the machine is in operation. Said arms, g, are shown in Figure 4, and in
Figure 41. The inner side of the arm, g, has a groove therein, as shown in dotted

page_text: lines, in which groove the ends of said spool-shaft engage when in operative position,
the engagement of the shaft with the groove serving to retain said spool in proper
position to permit it to rotate, and allowing the spool to adjust itself to its varying
positions relative to the drum on which it lies as the roving thereon is gradually
unwound. The said roving-spools are provided with a flange at each end, as shown in
Figure 1, the borders of which project slightly over the ends of the drum, 471, and
aid in keeping the roving-spools in proper position on said drum.
On the side of the plate, 463, are formed lateral projections, h, at its lower edge,
which are adapted to strike against suitable elastic material placed in two bunter-
cups, i, which are secured on the side or sides of each of the said posts on which the
said carriage-plates have their vertical movements. Said cups, i, are secured near the
lower end of said posts, as shown in Figures 3 and 4. The interposition of said elastic
material between the said stops, h, and said cups, serves to obviate any sudden shock
when the downward movement of the carriage is arrested by the striking of said
stops against the bunters.
On the side of one of each pair of carriage-plates is a cylindrical, or other suitably
formed stud, J, see Figures 4 and 41, said stud being perforated longitudinally as
shown in dotted lines in Figure 41, to provide for passing the end of a wire-
rope, 499, through it, and for suitably attaching the end of said rope to the
frame-plate.
A rack, 462, is socured adjustably against the outer side of each of the posts, 461
and 461, by a strap, m, which is held against the lower end of said rack by two bolts
which pass througli said straps into the standard to which said posts are secured, as
shown in Figure 4. By said means the rack is rigidly held in a vertical position
against the side of said post and extends between the aforesaid carriage-plates nearly
to the upper end of said post, as shown in Figure 41. By means of said strap-fastening
the said rack may be adjusted to extend more or less above the upper end of said
standard for a purpose hereinafter explained.
The plate, 463, which is one of the aforesaid pair of carriage-frame-plates, is
provided with a perforation of rectangular, or other suitable form, as shown in
Figures 4 and 41, and on opposite sides of said perforation are bolted suitable boxes
against the sides of said plate, in which is placed a short shaft having thereon a
gear, 466, having ratchet-connection with its shaft as shown in detail in Figures 45
and 46, within said perforation in the plate, and engages with the aforesaid rack, 462,
and on each end of said short shaft is fixed a beveled geared pinion, 479. By said
ratchet-gear connection, the shaft on which are the pinions, 479, is made to rotate
only when the carriage rises, so that rovings will be given out only while the carriage
is moving upward. In recesses, n, in the opposite edges of the said carriage frame-
plates (see Figure 41) are secured suitable boxes, 9, (see Figure 1) in which one end
of the shaft on which the drum, 471, is, is fixed, the opposite end of said shaft having
a bearing in a suitable box on the frame-plates on post, 277, (see Figure 3) said shaft
which is indicated by 375, having intermediate bearings in the carriage-frame-plates, d,
on posts, a.
By reference to Figure 4, which is an end view of the machine excepting the upper.
end of the frame thereof, it is seen that two shafts, 375, are located in the carriage
each side of the central portion of the machine, as shown in Figure 3, and on opposite
sides of the carriage, each of said shafts being provided with the said drums, 471, as
shown in Figures 3 and 4. Figure 4, shows the operating parts of the machine
which are attached to the carriage-frame plate at each end of the mule-spinner, and
those frame-plates have their vertical movements on the upright posts, 461 and 461ª
of the machine. The said operating mechanism which is attached to said frame-plates
at the ends of the carriage is not shown in Figure 3, for want of room to illustrate,
but Figure 4, clearly shows the arrangement thereof. The aforesaid shafts, 375, have
their ends projecting beyond the outer face of the said frame-plates at the ends of the
carriage, and the ends of said shafts have fixed thereon a double gear, 476, which
gears have an engagement with the aforesaid beveled pinions, 479, and with inter-
mediate gears, 477, having a free rotary movement on suitable studs on the end

page_text: plate, 463.
On each side of the carriage of the machine, and below each of the said
drums, 471, are arranged suitable delivery rollers between which the rovings, 319,
which are drawn from the spool, 470, pass on their way to the spindles, 428, as shown
in Figure 4.
The two lower of said delivery rollers, which are three in number, as clearly
shown in Figures 4 and 5, are hung on shafts, 334 and 335, which have fixed
thereon pinions, 478 and 491, the latter engaging with the aforesaid intermediate.
gear, 477, and an intermediate pinion, 481, is hung under said pinions, 478
and 491, and has an engagement with the latter named two pinions, as shown in
Figure 4. The third delivery roller, 318, or "top-roller" of the usual construction
rests by gravity on the aforesaid two delivery rollers. The boxes in which the ends
of the said shafts, 334 and 335, have their bearings, are suitably supported on the said
carriage-frame-plates under the end of the above-referred-to arm, 316, the said set-
screw in the latter being screwed down against the upper side of said boxes to retain
them in proper operative position.
From the above-described construction of the carriage of the machine it should be
understood that said carriage consists of a series of said frame-plates united by angle-
irons extending the whole length of the machine, the carriage frame-plates at each
end of the machine carrying the geared connections shown in Figure 4, which geared
connections control the movements of the roving-spools and delivery rollers which are
on the carriage each side of the central portion of the machine, motion being imparted
to said geared connections at each end of the carriage by means of the engagement of
the gear, 466, with the racks, 462, on the end-posts of the machine, said gear, 466,
being actuated by the reciprocating vertical movements of the entire carriage of the
machine, as below described.
The aforesaid ratchet-gear, 466, whose detail of construction is illustrated in
Figures 45 and 46, has a free rotation on the shaft, 467, in one direction, and by
means of ratchet-teeth, as shown, on the inner side of its rim, said gear has an
engagement with a series of pawls, 464, which are hung on pins, 469, on two
disks, 468, one on each side of said gear, which disks are keyed to said shaft, 467, on
which are secured the above-mentioned beveled gears, 479. Thus, when the carriage
is moved upward the gear, 466, engages with said pawls and the shaft, 467, and
all of the above-described gearing connected therewith is given a rotary motion, but
when the carriage moves downward the gear, 466, turns freely on its shaft and has no
effect upon said gearing.
The above-described carriage of the machine is suspended by a series of wire-ropes,
when not resting on the aforesaid bunter-cups, i, said ropes being four in number and
all secured side by side, about centrally between their ends in the weight, 500, which
serves as a counter-balance to the said carriage, but is somewhat lighter than the
latter to permit the carriage to drop down when free from the restraining action of
mechanism below described, and to actuate certain operative parts of the machine as
below set forth. Said ropes may be secured to the said weight in any suitable
manner but it is preferable to double them around a block having the form shown in
dotted lines in Figure 1, whereby the ropes have such a broad bearing that no danger
exists of their being so bent or kinked as to impair their strength, said block being
firmly secured in the weight by any suitable means. The ends of the said four ropes,
which ropes are indicated by 499, (there being eight ends) are carried upward from
the said weight, as shown in Figures 1 and 3, above the frame of the machine and are
drawn in opposite lateral directions from the center of the machine over said frame
and over wheels, w, and pulleys, 366, on the latter, and each of said rope-ends is
carried downward and secured to a pair of the above-described carriage frame-
plates by being attached as described, to the stud, J, thereon (see Figures 4
and 41).
The said counter-balance weight, 500, has a sliding connection with a suitable
guide-rod, or rods at each end thereof, as shown in Figure 1, whereby it is suitably
guided in its vertical movements.
That part of the spinning-mule usually termed the "Head" is, in this machine

page_text: embraced almost entirely in that part of the structure shown in front elevation in
Figures 1 and 2, between the standards, 2 and 3.
The driving shaft of the machine, 141, is hung in suitable boxes, 140, in two
standards, 5, one of which is shown in Figures 1 and 2, the other being located near
the main shaft of the machine, 188. Said driving shaft, 141, has thereon a driving
pulley, 136, having a belt-connection with any suitable driving power from either
above or below. The said driving pulley, 136, has a frictional connection with the
driving shaft, 141, as and for the purpose below described. The inner end of the
driving shaft, 141, has fixed thereon two beveled gears, not shown in the drawing, one
of which, the one nearest the end of said shaft, engages with a beveled
142,
gear,
which is fixed on the main shaft, 188, of the machine, and the second gear engages
with a beveled gear, 137, which is fixed on a sleeve, 133, which rotates on said main
shaft. Because of the said geared connection of said driving shaft with said gears, 112
and 137, which are engaged on opposite sides of the driving shaft, the aforesaid main
shaft, 188, and the sleeve, 113, on said shaft are given rotary motions in reverse
directions. The said main shaft, 188, is hung in suitable boxes in the standards, 2
and 3, as clearly shown in Figures 2, 7 and 8, the main shaft extending, as shown,
unbrokenly between said standards, one end thereof projecting beyond the sides of
standard, 2, and having fixed thereon a beveled gear, 90, adjoining the shaft-box, 91,
the box in standard, 3, being indicated by, 148.
A pulley, 410, is fixed on the hub of the portion, 409, of a clutch which is free on
said main shaft, 188, and said pulley has a belt-connection with a pulley on a counter-
shaft, 65 (see Figures 1, 2 and 6) said counter-shaft having thereon the pulley, 351,
which has a connection by the belt, 52, with the pulley, 352, which is fixed on the
drum-shaft, 82, on which are carried the drums around which the spindle-bands are
carried, said drums being indicated by, 84. The above-described connections with
the pulley, 410, indicate all of the connections between the main shaft and the drum-
shaft.
A short shaft, 89 (see Figure 2) is supported in suitable bearings which are bolted
to the side of the standard, 2, and on one end of said shaft is fixed a bevel gear, 88,
which engages with said gear, 90, on the end of the main shaft, 188, and on the
opposite end of the shaft 89, is a second bevel gear which engages with a bevel
gear, 85, having a hub which is keyed to a sleeve, 229, (see Figures 2, 4 and 28)
which sleeve encircles and rotates on the end of the shaft, 11, which is hung in
bearings on the standards, 2 and 3, parallel to the main shaft. Said sleeve, 29,
rotates in a bearing, 233, attached to standard, 2, and extends in a line with
shaft, 11, towards the center of the head, and has the clutch, 230, keyed thereon in
the usual way of constructing sliding clutches.
The end of said sleeve, 229, extends somewhat beyond the face of said clutch, 230,
and enters the side of a corresponding clutch, 225, which is keyed to the
shaft, 11.
The above-referred-to vertical movements of the carriage are controlled by the
connection of a wire or other suitable rope, 189 (see Figures 1, 2 and 6) which
runs over a pulley, 503, on the said weight, 500, and the ends of said rope are
secured to two winding-scrolls, 190 and 205, said scrolls being located on a transverse
shaft, 30 scroll, 190, being fixed to said shaft, and scroll, 205, having, of itself, a
free rotation thereon, but has an adjustable connection, as below described, with a
hub, 357, which is keyed to said shaft, 30, for the purpose of varying the speed
of the upward movement of the said carriage to the end that the said movement
may be gradually retarded to a greater or less degree, in order to adjust the
movement of the carriage to the drawing of the yarn, the latter meanwhile being
twisted.
The details of the said adjustable connection of the scroll, 205, with the hub, 357,
are shown in Figures 16 and 17, Figure 16, showing said scroll and hub in section on
a part of said shaft, 30, and Figure 17, showing said shaft in section, and a rear-side
elevation of the scroll and hub, the latter having thereon a flange as shown, provided
with a series of bolt-holes, and the scroll is provided with corresponding holes, so that

page_text: the scroll, 205, may be set to different positions relative to the hub, in order to
cause the end of the rope, 189, which is attached thereto to be wound thereon with a
greater or less degree of rapidity, according to the diameter of the scroll on which it
winds.
The rotary movement of said shaft, 30, is controlled by a worm, 27, which is fixed
on the shaft, 26, which engages with a worm-gear, 354, on said shaft, 30, the latter
running in suitable bearings in two standards, 28 and 196, (see Figures 1, 2 and 6).
The said shaft, 26, runs in bearings in the standards, 6 and 56, and is in front of and
parallel with the said main shaft, 188, and has thereon a gear, 36, which engages with
a gear, 35, which is fixed on the end of the sleeve of a clutch, 25, on the main
shaft, 188, the latter running freely in said sleeve. The end-thrust of the said
shaft, 26, on which is the worm, 27, is received on the point of a center-stud
(see Figure 2) which is fixed on an arm which projects from the upper end of said
standard, 56.
In order to provide for running the aforesaid spindle-driving drum, 84, any given
number of revolutions during each draw of the yarn, and in that way providing for
giving to it more or less "turns to the inch" as it is sometimes expressed, and so.
regulating the twist as may be desired, the clutch, 409, on the main shaft, 188, has
an automatically operating connection with the clutch-shipping rod, 34, (see Figures 2,
5, 6, 7 and 8) by the below-described means, whereby after the pulley, 410, which is
secured on the clutch, 409, has made a certain number of revolutions, said clutch is
disconnected from the keyed-clutch, 59, and the pulley is stopped, thereby stopping the
spindle drums.
Referring to Figure 7, a bed-plate, 1, is shown extending horizontally between the
standards, 2 and 3. Said bed-plate has its ends resting on suitable projections on the
opposite sides of said standards. The above-referred-to clutch-shipping rod, 34, is
supported in a horizontal position under the main shaft, 188, in bearings, 122 and 63,
on said bed-plate, and one end of said shipping rod passes through the standard, 96,
which is secured to the floor. A spiral spring, 95, is placed on said shipper-rod
between the said standard, 96, and a collar, 64, on said shipping rod, said spring
being so compressed between said collar and standard that it acts to move said rod
and the parts connected therewith to the right (see Figure 7).
Referring to Figure 2, it is seen that the spindle-driving drums are carried on the
shafts, 83, which are coupled to the shaft, 82, within the head of the machine, the said
drums being shown in position in the machine in Figure 3, between the several
standards thereof, the drum-shaft extending through said standards and having a
bearing in each one thereof, as shown in Figure 4. The said drums reach from
standard to standard, as shown.
The spindles, 428, have their steps in wooden rails, 261 and 186, which are bolted
on one side of the angle-irons 80, which extend longitudinally from standard to
standard on either side of the head of the machine and on both sides of the latter and
form parts of the frame thereof.
The bolster-rails, 271 and 182, are in a similar manner bolted to the angle-irons, 79,
located above said angle-irons, 80, as shown in Figure 9, which illustrates in a some-
what enlarged view, a portion of the side of one of the intermediate standards,
either 2ª, or 2b, looking towards the head of the machine. Said Figure 9, shows two
of the spindles, an end-view of the drum, and the bands connecting the latter and the
spindles. It will be seen by said Figure and Figure 2, that the spindles are arranged
transversely of the machine in inclined positions, in two rows, the spindles crossing
each other centrally over the axial line of the drum, 84. By this arrangement the two
rows of spindles are driven by the same drum. By referring to Figure 4, the positions
of the ends of the spindles relative to the said delivery rolls on the carriage above
them, is clearly shown, and Figure 2, shows portions of the said two rows of spindles
and the driving-drum, on each side of the head of the machine. Two rods, 432,
and 434, have their ends supported in a bracket, 430, on said standards 2°, to 3º, (see
Figures 3 and 9) and extend near the inner sides of the spindle-whirrs to keep the
spindles in their steps.

page_text: In order to describe the construction and action of the parts of the machine which
are not embraced in the foregoing description, let it be assumed that the carriage has
moved to its highest position, the yarns, as shown in Figure 1, being drawn between
the bobbins on the spindles and the said drawing rollers on the carriage, the latter
being now ready to descend. The positions of the parts of the machine as shown in 5
Figures 1, 2, 5, 6, 7 and 8, are those which said parts occupy when the carriage is up,
as aforesaid.
At this time the main shaft, 188, is rotating, and carries with it the clutch, 59,
which is in engagement with the clutch, 25, on which gear, 35, is keyed, thereby
giving rotary movement to the above-described scroll-shaft, 30, and turning the
scrolls, 190 and 205, to unwind the rope, 189, letting the weight, 500, rise, and the
carriage move downward by its own weight, and when the carriage so moves it is
necessary that the twisted yarn be wound onto the bobbins on the spindles, and be
properly guided while it is wound on, and the yarn-guiding devices are constructed
and operate as follows.
·
In Figures 1 and 2, are seen on the front side of the machine two parallel rods, 15
and 16, which have suitable bearings on the aforesaid standards of the machine, there
being a pair of said rods on each side of the machine and extending the whole length
thereof, said rods being adapted to have a rocking motion, as below described. It is
well known to spinners that what are termed "building and following wires" located
longitudinally near the ends of the spindles and bobbins, are employed for guiding the
yarns onto the bobbins, and in this machine, z, z, indicate the said wires, (see
Figure 2) z, being the following wire. The said following wire, z, is attached to a
suitable number of arms, 347, and 52, (see Figures 2 and 4) and said arms are fixed
on a rock-shaft, 15, the arms, 52, being located at the ends of the groups of spindles
and the arms, 347, being located intermediately between said end arms and made in
form shown in Figure 4, to provide for allowing the building wire which is attached
to the arms, 53, to swing backward beyond the ends of the spindles, about as shown in
Figure 4. The said arms, 53, are fixed on the rod, or rock-shaft, 16. The relative
position of the yarn and said wires, and ¹, is that the latter or the building wire is
in front of the yarn, and the follower wire, a, is back of it, and is held against the
yarn by a gentle force sufficient to keep it in contact with the building wire by several
weights, 241, one of which is shown at the left in Figure 1, and two of which are
shown on opposite sides of the machine in Figures 4 and 6, said weights being
suspended from grooved segments, 242, as shown in said Figures, fixed on said
shafts, 15. The building wire is held against the yarn and presses the latter towards
the base of the bobbin by several weights, 240, which are hung on grooved segments
on the rod, 16.
The weights governing the pressure of the building wire against the yarns are
heavier than those which actuate the follower wire in the opposite direction so that
the movements of the latter wire are under the control of the building wire, and the
successivę movements of the rod, 16, during the movements of the carriage, are
actuated by the below-described devices.
While the twist is being given to the yarn and during the short rest of the carriage
in its upmost position, the positions of the aforesaid arms which sustain the building
and following wires are those shown in Figure 4, whereby the yarn is so held that it
slips off the point of the spindle while the latter revolves and thereby the yarn becomes
twisted. Figure 6, represents the position of the arms which sustain the said wires
when the carriage commences to descend and little or no yarn has been built on the
bobbins on the spindles, the position of the upper end of said arms when the carriage
begins to descend being always at the base of the yarn-cones.
Figure 31, represents one of the bobbins and shows thereon a representation of
the yarn-cone which is the result of the first winding on when the filling of the bobbin
is begun, that is to say, it represents a yarn-cone which is the result of more or less
winding on motions according to the coarseness or fineness of the yarn, and the
successive windings on of yarn, the latter being guided by the said building wire, result
in a full bobbin having substantially the form shown in dotted lines in said Figure 31.

page_text: 10 impart the aforesaid requisite vibratory motion to the building wire, 2 the
following devices are employed.
Referring to Figures 1, 2 and 6, there is shown in said Figures a drive-chain, 37,
which runs over a pulley, 363, hung in suitable hangers on the ceiling of the room
over the machine, said chain pending in a double position, as shown in Figure 1, said
chain passing around a pulley, 212, (see Figure 6, and also Figure 2, wherein said
pulley is shown in dotted lines on its shaft, 33). The said shaft, 33, is hung in suitable
bearings, 213 and 32, which are supported on the bed-plate of the machine, and
extends transversely of the machine at right angles to, and below the main shaft, 188.
A gear, 31, is fixed on a shaft, y, (see Figures 14 and 15) which is adapted to rotate in
suitable bearings in the bed-plate, 1, by means of a pinion, 339, which is fixed on said
shaft, 33, (see also Figure 29) said shaft, y, extending in a line with the shaft, 33,
above it, and having fixed thereon back of the standard, 338, (see Figure 6) a
cam, 340, which cam is shown in side elevation in Figure 47, in dotted lines in
Figure 14, and in edge view in Figure 15. The cam, 340, has imparted to it a
reciprocating rotary motion by the downward and upward movement of the carriage
through the above-described connection of the carriage with the shaft, y, by means of
the chain, 37, the wheel, 212, its shaft, 33, and the geared connections between the
latter and said shaft, y.
Connection is made between the said cam, 340, and the above-mentioned rods on
which the building-wire arms are hung whereby said arms are given the aforesaid
vibratory motion, by the below-described devices.
A vertical tube, 38, (see Figures 2, 6, 14, 15 and 47) is hung on an arm, 42, by a
collar and nut connection, as shown in Figure 6, which arm, 42, is fixed on a rock-
shaft, 47, which extends horizontally of the machine in the head thereof. The said
tube, 38, is internally screw-threaded, as shown in Figure 47, and a vertical rod, 106,
is located in said tube and has a screw-connection with its interior, the point of said
rod reaching below the end of said tube and having a bearing on the periphery of the
said cam, 340. The purpose of the screw-connection between said rod and tube will
be described farther on. When the carriage is at the top of the frame of the machine
the cam, 340, and the lower end of the rod, 106, occupy relatively, the positions
shown in Figure 47, and as the carriage descends said cam is rotated in the direction
shown by the arrow at the right in said Figure, thereby causing the rod, 106, and its
connected tube, 38, to be gradually lifted, thereby rocking the said shaft, 47, with
which it has a connection, as aforesaid. On said shaft, 47, occupying a pending
position, as shown in Figure 6, is an arm, 22, having a connection with the aforesaid
rods, 16, on which are the building-wire arms, by means of the connecting rods, 24,
and 201, and the arms, 23 and 200. The vertical motion which is given to the said
rod, 106, and tube, 38, by the said rotary motion of the cam, 340, is sufficient only to
give to the said building-wires and their arms a vibratory motion equal to the length
of the yarn-cone which is to be built onto the bobbin, the said cam being of such form
as will produce the required conic form when the yarn is wound on, that form being
shown, substantially, in Figure 31, in which, w¹, indicates the yarn-cone on the bobbin.
The movement of the building-wires in the formation of the cone commences at the
base thereof and moves towards the apex of the cone whenever the latter may be in
process of formation on the bobbin.
It will be understood that in order to fill a bobbin with yarn by forming thereon,
so to say, a series of successive conic formations of wound yarn, that the building-
wires and their arms must have vibratory movements which commence successively
farther and farther from the base of the bobbin with each descent of the carriage while
the bobbin is being filled, and the above-described changes in the starting position of
the building-wires are produced by the following mechanism.
The extent of the projection of the lower end of the rod, 106, below the end of the
tube, 38, determines the starting position of the arms to which said building-wires are
attached when said wires are about to be moved from the base of the yarn-cone upward,
and consequently, after doffing and having placed empty bobbins on the spindles, the
rod, 106, is screwed upward to throw the building-wires to the base of the bobbin, or
B

page_text: to bring the lower end of said rod to the position relative to the lower end of the
tube, 38, which is shown in Figure 15. As the building of the yarn goes on, the said
rod, 106, is given an intermittent rotary motion by each successive downward move-
ment of the carriage, thereby causing the above-referred-to changes in the starting
points of the building-wire motion.
A rock-shaft, 18, is hung in suitable bearings on the standards, 2 and 3, (see
Figures 2 and 6) and on said rock-shaft is fixed an arm, 46, (for details see
Figures 10, 11, 12 and 13,) which arm, 46, has an adjustable connection by the
bar, 97, with a pawl-arm, 99, which has a free vibratory motion on the short
shaft, 103, which is hung in a bearing, 45, which is secured to the girder, 20, which
connects the standards, 2 and 3. A ratchet-wheel, 101, is fixed on shaft, 103, at the
side of arm, 99, and a spring-pawl, 108, on arm, 99, engages with said ratchet-wheel.
A ratchet-retaining hook, 102, is secured on the girder, 20, and engages with said
ratchet-wheel to prevent it from turning backward. The said shaft, 103, has on its
end a beveled gear, 105, which engages with a bevel gear, 104, through which the said
screwed rod, 106, passes, and the latter has a sliding spline connection with the bub
of said bevel gear, 104, the latter having a suitable bearing on said girder, 20. As
seen in Figure 12, an arm, 100, is bolted to the top of said girder, 20, and has on its
end a bearing, as shown in Figure 10, above the gear, 104, whereby the latter is held
in position in its bearing,
Said bearing, 45, which supports the shaft, 103, has therein an eccentric sleeve, a,
(see Figure 13) through which said shaft passes, and on said sleeve is an arm or
handle, 98, whereby said sleeve is turned to lift shaft, 103, and the gear, 105, thereon,
so as to disengage the latter from the gear, 104, on the rod, 106, to leave the latter
free to be turned by the hand-wheel, 107, to bring its lower end nearer the lower end
of the tube, 38, to adjust the said guide-wires to a position as aforesaid at the base of
the bobbin after doffing and putting new bobbins on the spindles, after which the
handle, 98, is swung downward, bringing said gears, 104 and 105, into re-engagement
preparatory to filling a new set of bobbins.
The above-referred-to adjustable connection (by the bar, 97) between the
arms, 46 and 99, having longitudinal slots therein as shown, is provided for the
purpose of imparting to the shaft, 106, a greater or less degree of rotary motion by
the action of the arm, 46, so that thereby the action of the building wires over the
bobbin may be in accordance with the size of the yarn spun and being wound thereon.
The rocking motion is given to the said shaft, 18, on which is said arm, 46, by the
downward movement of the carriage during the latter part of said movement, as
follows:
Two plungers, 263 and 221, (see Figures 39 and 40) have vertical movements in
suitable supports in the girder, 20, one at each end of the head of the machine (see
Figures 2 and 5). Said shaft, 18, has fixed thereon two arms, 78 and 179, the ends of
which are bifurcated to receive the lower ends of said plungers. Said carriage in
moving downward as above described, causes a projection, v, and s, on the frame-plates
of the carriage which move up and down on the posts, 369 and 277, (see Figure 3) to
come in contact respectively with the plungers, 263 and 221, thereby forcing them
downward against said arms, 179 and 78, thereby rocking said shaft, 18, to swing the
end of arm, 46, towards the center of the head, and operate the screw-rod, 106, to
move it downwardly through the tube, 38.
وو
During the above-described yarn-building operations, the usual "winding on
operation has proceeded during the down-movement of the carriage, whereby the yarn
which was spun while the carriage moved upward was placed on the bobbin, the latter
being given the requisite rotary motion to effect said winding, by the following
mechanism :
The above-referred-to shaft, 11, has fixed thereon a scroll-pulley, 138, (see Figures 2,
5 and 24) to which is attached the end of a rope, 172, which passes over a pulley, a³,
which is hung in suitable hangers on the ceiling of the room in which the machine is
located, and on the pending end of said rope is attached a weight, 294, which is guided
in its vertical movements between two vertical guides, 133 and 134. During the

page_text: ascent of the carriage, the descent of which has just been described, the shaft, 11, and
the scroll, 138, thereon, were rotated and the rope, 172, having the weight, 294,
attached to it was wound on said scroll, thereby lifting said weight to about the position
shown in Figure 1. The circumstances under which said shaft and scroll were
rotated will be hereinafter described. The said shaft, 11, has fixed thereon a ratchet-
wheel, 144, and adjoining said ratchet-wheel, 144, on a suitable support on the
standard, 3, is hung a pawl, 143, (see Figure 5) having a curved arm thereon above
its pivot-point, and to the end of said curved arm is pivoted a bar, 178, having secured
thereon a catch-block, a*. The end of said bar, 178, rests on a lip on the side of an
arm, 179, which is fixed to the aforesaid shaft, 18, said lip being the lower edge of a
recess in the side of the arm, 179, a spring, as shown, being attached to the upper side
of the bar, 178, and having a bearing against the upper side of said recess to hold said
bar downward against said lip with a yielding force.
During the aforesaid rotation of the scroll, 138, and shaft, 11, the pawl, 143, rested
in engagement with the ratchet-wheel, 144, and was there held by a suitable spring
between it and the adjoining edge of the standard 3. The said pawl remains in
engagement with said ratchet-wheel until the aforesaid winding on operation is ready
to take place, at which time the said pawl is disengaged from the ratchet-wheel, as
hereinafter described.
A pulley, 282, is placed on the shaft, 11, said pulley not being fixed on said shaft
but being made to rotate with it by its engagement with two flat coiled springs, 160,
the inner ends of which are secured to two hubs which are keyed onto said shaft and
their outer ends are hooked on to the ends of a pin passing through one of the arms of
said pulley near the rim thereof, (see Figures 5, 23 and 24). The hub of said pulley
has on one side thereof and adjoining the junction of one of the arms with the hub,
two projections, e², with which two arms, es, ou said hubs, 159, engage when the pulley
is rotated to a certain extent between the hubs, to serve a purpose hereinafter described.
The said pulley, 282 is connected by a belt, 162, (see Figure 2) with a friction
pulley, 283, which is on the drum-shaft, 82, in the head of the machine and is in
engagement with said shaft during the winding on motion. Figure 23, is a sectional
view of the above-described pulley, 282, the springs, 160, and their hubs, and of a
portion of shaft, 11.
The number of pounds that the weight, 294, weighs determines the tension under
which the yarn is wound onto the bobbins, because it furnishes the power which turns
the drum-shaft and the spindles in winding on, through the scroll, 138, shaft, 11, and the
pulley, 282, but said scroll regulates that tension and keeps it uniform because the
rope, 172, is tangent to the large part of the scroll, while the yarn is building upon
the base of the cone, and the yarn on the cone and the rope on the scroll move towards
the smaller diameters of each simultaneously.
The above-described winding on action continues until the carriage descends far
enough to cause the cam, t, on one of the carriage frame-plates, 313, (see Figure 5) to
strike the inclined edge of the long arm of the elbow-lever, 187. Said elbow-lever
is pivoted to the side of the standard, 3, and the short arm extends by the side of the
aforesaid bar, 178, the latter having a slot in it as shown, through which a bolt passes
and is screwed into the said short arm of the elbow-lever. Consequently, when said
cam, t, engages with the said long arm of the elbow-lever, its short arm swings
upward carrying the end of the bar, 178, with it far enough to lift the catch-block, a,
clear of the said lip on the arm, 179, and while the end of bar, 178, is in this position
the said spring behind the pawl, 143, swings the latter into engagement with the
ratchet-wheel, 144, and thereby stops the winding on motion.
After the conclusion of the aforesaid winding on motions and just before the carriage
reaches its lowest position, it actuates the following devices to cause the building-wire
arms to swing outward to the position shown in Figure 4, where they rest during the
next ascent of the carriage.
In Figure 2, near the inner sides of the standards, 2 and 3, are shown the upper
ends of two lovers, 219 and 256, one of which, 219, is shown in Figure 6, and the

page_text: other, 256, is shown in Figure 5. Said levers have one edge inclined, as shown, and
are attached by the other end to a rock-shaft, 204, which is hung in suitable
bearings on the girder, 20.
When the carriage bas descended sufficiently far to cause the cams, r, and t¹, on the
carriage frame-plates, 371 and 313, to strike the ends of said levers, the latter are
swung laterally rocking shaft, 204, and causing the arm, 22, heretofore referred to, to
be swung on its pivot through its connection with shaft, 204, by the arm, 203, thereon,
and the connecting bar, 21, the said arm, 22, being connected with the rods, 16, on
which the building-wire arms are supported, as heretofore described.
In order to retain the said building-wires and their arms in the above-referred-to
outward positions shown in Figure 4, while the carriage moves upward and the
spinning is taking place, the shaft, 47, and its connections are retained in the positions
to which they are brought by the above-referred-to swinging action of the levers, 219
and 256, by retaining the tube, 38, and its rod, 106, temporarily in the lifted position
to which it is brought when the building-wires are moved outward as aforesaid.
Referring to Figures 14 and 15, it will be seen that the said tube, 38, has at its lower
end a collar, f, thereon and in said Figures is shown portions of the main shipper
rod, 34, (shown in Figures 7 and 8, under the main shaft, 188) said rod running to
one side of the lower end of said tube, 38, and having thereon an arm, 341, which is
moved by a longitudinal action of said shipper-rod below described, whereby the end
of said arm is brought under the said collar, f1, when the tube, 38, is raised up, as
just described, holding said tube and rod in said upward position during the movement
of the carriage upward while the yarns are being spun.
The above-referred-to shipper-rod, 34, is given a longitudinal sliding motion to carry
the said arm, 341, under said collar, f, by the downward movement of the plunger, 114,
the latter being actuated by the arm, 164, on the aforesaid rock-shaft, 18, said arm
striking the upper end of a collar, 279, on said plunger (see Figure 5). The manner
in which the rock-shaft, 18, is actuated by the descent of the carriage as heretoforo
fully described.
A short shaft, 110, (see Figures 5, 7 and 8) is hung transversely between
the main shaft, 188, and the said shipper-rod, 34, in suitable bearings, 109, on
standards on the bed-plate of the machine, and on the shaft, 110, between said
bearings, is fixed an elbow-lever consisting of a long arm, 287, and a short
arm 111, each of which arms has a separate hub, as shown in Figure 5,
whereby it is keyed to said shaft and held in proper position. The aforesaid
plunger, 114, extends through the bed of the machine slightly, by the side of the short
arm, 112, and has a collar, 111, thereon which acts against said arm and rocks the
shaft, 110, and thereby the lower end of the long arm, 287, of said elbow-lever is carried
against a collar, 118, on said shipper-rod, thereby giving it the aforesaid longitudinal
motion to the left, in Figures 8 and 7, against the force of the above-referred-to coiled
spring, 95, which is fully shown in Figure 2, and said longitudinal movement of the
shipper-rod carries the said arm, 341, under the collar, f1, on said tube, 38.
For the accomplishment of certain actions of the machine it is requisite that the
shipper-rod, 34, be retained in the position to which it is moved by the above-described
action of the plunger, 114, and it is so held by mechanism which is illustrated in detail
in Figure 32. On the bed-plate of the machine is secured a bearing-block, 122,
heretofore referred to, through which said shipper-rod passes, the latter having a
pin-socket in its side, as shown in Figure 8, to receive the end of a stop-pin, 399, which
is supported partly in said block, 122, and partly in a bearing, 250, one end entering
said block and being forced against the side of said shipper-rod by a spring, 291,
between said bearing, 250, and a collar, 400, fixed on said stop-pin. When said
shipper-rod, 34, is given its said longitudinal motion the said socket in the side is
brought opposite the end of the stop-pin, 399, and the latter slides end wise by
spring, 291, carrying the end of the pin into said socket and thereby holding the
shipper rod from further movement until, by the action of other devices hereinafter
described and partly shown in Figure 32, said pin is withdrawn,

page_text: The said longitudinal movement of the shipper-rod, 34, by its connection with the
sliding clutch, 59, (see Figures 7 and 8) by the arm, 406, causes said clutch to move
out of engagement with that part of the clutch, 25, on which the gear, 35, is secured,
thereby stopping the rotary movement of said gear and the unwinding movement of
the scrolls, 190 and 205, heretofore described, coincident with the arrival of the carriage
at its. lowest point, following the said disengagement of the clutch, 59, from the
clutch, 25, by the movement of the shipper-rod, 34, three clutch-engagements
are effected simultaneously by the said longitudinal movement of the rod, 34, as
follows:
:
The sliding clutch, 9, on the sleeve, 113, is carried into engagement with one end
of the clutch, 25, thereby again starting the gear, 35, to give the winding motion
to the scrolls, 190 and 205, thereby again elevating the carriage.
The same movement of the shipper-rod, 34, which causes the said engagement of
clutches, 9 and 25, effects the engagement of the clutches, 59 and 409, the pulley, 410,
being fixed on the sleeve of the latter, as above-described, and through the rotation
of said pulley whose connection with the drum-shaft has been described, the spindles
are set in motion.
On the hub of the aforesaid arm, 406, shown in Figures 7 and 29, and extending
rearwardly from said hub, is a projection, 2, through which a bolt passes into a slot
at the end of a lever, 210, said lever being pivoted on the bed-plate, 1, and
having a vibratory motion in a horizontal plane, and one end of said lever, 210,
has a pivotal connection with a sliding collar, 208, (see Figures 29 and 30) having
a hook thereon, as shown, which collar is located on a sliding shipper-rod, 358,
which is located under the above-described shaft, 11, (see Figures 6, and 27)
and is supported in suitable bearings, 195 and 426. A clutch arm, 231, shown
in side elevation in Figure 28, and in section in Figure 29, is fixed on said
shipper-rod 358, and at the base of said arın, 231, is secured a spring-hook, 438,
adapted to be engaged with the aforesaid hook on the collar, 208. A spiral
spring, 206, is placed on the shipper-rod, 358, between the bearings, 195 and a
collar, 207, on said rod. The above-described longitudinal movement of the shipper-
rod, 34, causes, through the said lever, 210, a movement in the opposite direction of
the said collar, 208, which is connected with the shipper-rod, 358, by the above-
described hooks, of which, 438, is one, and the clutch-arm, 231, which is fixed on
the rod, 358, thereby effecting the endwise movement of the latter, and said clutch-arm
against the force of said spring, 206, which movement carries the clutch, 230, (see
Figure 27) into engagement with the clutch, 225, on the shaft, 11, thereby setting in
motion the winding scroll, 138, and carrying upward the above-described weight, 294,
(see Figures 1 and 4).
When the carriage of the machine is raised to the upper end of the frame, as
described, it is held in its upward position by the rope, 189, which is wound upon
the scrolls 190, and 205, as described, and through the connection of the scroll-shaft
with the gear, 35, as set forth, the latter being on the sleeve of clutch, 25, which
gear, when the carriage is up, is free from engagement with any of said clutches,
the said carriage is held in said position by whatever may be the resistance between
the worm-gear on the scroll-shaft and the worm on shaft, 26, which has a geared
connection with said gear, 35. And lest said worm and gear resistance may not be
sufficient to hold the carriage up, the gear, 35, as shown in Figure 6, is provided
with ratchet-teeth, gl, and a pawl, 405, (for details see Figures 48 and 49) is pivoted
on the upper end of a standard, 356, on the bed-plate, 1, near the shipper-rod, 34.
Said pawl has a pending portion, g³, which extends over said shipper-rod and has an
engagement with a pin on said rod. A spring, 355, is attached to the standard, 356,
the free end of which bears against the hooked end of said pawl and swings it against
the said ratcheted part of the gear, 35. When, by the said movement of the shipper-
rod, 34, to the left whereby the carriage is carried upward, the pawl, 405, is
permitted, by the action of spring, 355, to swing against the ratchet-tooth in gear, 35,
and remain there to prevent said gear from turning backward by the weight of the
carriage until said shipper-rod is moved in the opposite direction, and then the said

page_text: pin in the shipper-rod, engages with the pending part, g³, of the pawl and swings it
away from the side of the gear, 35.
During the time that the carriage is in its upward position and while the yarn is
receiving its twist, and the shipper-rod, 34, having been inoved to the left as described,
to cause the carriage to rise, the pins, 401 and 415, (see Figures 7, 8, 32, 36 and 37)
have their lower ends resting in slots in the side of said shipper-rod, the slot in
which pin, 401, rests being the longer, and said pins are successively disengaged
from said rod as and for the purpose hereinafter described. Said pin, 401, is forced
downward by a spring thereon, 403, which holds it in said slot, and the pin, 415, is
forced downward by the action of the above-referred-to upwardly projecting arm, 406,
which is fixed on the shipper-rod, 34, a laterally projecting part of said arm being
made, by the movement of said rod, to strike an arin, 61, which is fixed on a shaft, 2,
in a standard, 63, (for details see said Figures 36 and 37) which is secured to the
bed-plate of the machine as shown.
On the said shaft, 2, on which said arm, 61, is fixed are fixed two other arms
extending in the opposite direction from the latter and numbered, 421 and 420, the
latter being behind the former one and being shown in side elevation in Figure 7.
The said arms, 420 and 421, extend over the top of said standard, 63, and their ends
act against the top of a yoke which is connected to said standard and consists of two
bolts, 414 and 416, passing vertically through the standard, as shown in Figure 37,
having their opposite ends united by two cross-bars, 419 and 424, the upper one of
which cross-bars has secured therein, over the shaft, 34, the aforesaid pin, 415. Said
yoke has a free vertical movement in the standard, 63, being carried with said pin, 415,
downward by said arms, 420 and 421, and being lifted up by spring, 425, (see
Figure 8) when it is free to be moved in that direction, thereby carrying said pin out
of the above-referred-to slot in the shaft, 34.
When the aforesaid yoke which carries the said pin moves downward by the said
arms, 420 and 421, it is held down for a certain time by the following-described
device. A shaft, 67, rotating in bearings, 66 and 418, has together with the below-
described mechanism hung on said shaft, an intermittent, reciprocating vertical
motion. The said bearings in which is hung the shaft, 67, are attached to the ends
of two bolts, 413 and 417, which pass through said standard, 63, and have attached
to their lower ends a yoke-piece, 422. The aforesaid bolts, 414 and 416, pass freely
through said yoke-piece. A spring, 423, secured under the bed-plate bears against
the under side of the yoke-piece, 422, and lifts it up together with the shaft, 67, its
bearings, and the parts attached thereto. The said upward movement of the last
named parts is permitted by the withdrawal of an arm on a collar, 64, (see Figure 8)
from above the said yoke-piece, 422. The said collar, 64, is fixed on the said
shipper-rod, 34, and when it moves to the left, as in Figure 8, the said action of the
arm on the said collar takes place.
The said devices which are connected with the shaft, 67, consist of a collar, 68, having
thereon two arms, 02, and, o³, which is free on said shaft, a bevel edged worn-gear, 69,
and a grooved pulley, 220, both of which are keyed to said shaft. A spring, 427, one
end of which is secured to the hub of the arm, 61, (see Figures 7 and 8) has its free
end bearing upon the end of the arm, o², which adjoins said armı, 61, and said spring
serves to swing said arm and its collar, 68, so as to bring the end of arm, o2, over
the said yoke to which the pin, 415, is connected and hold it there until released.
When the said shipper-rod, 34, occupies a position as shown in Figure 8, which
does not permit the said pin, 415, to enter the slot in said rod, the arm on the
collar, 64, is in engagement with the yoke-piece, 422, thereby holding the shaft, 67,
and the worm-gear, 69, thereon, in a downward position, as shown in Figure 36, so
that said worm-gear is separated from the worm, 70, which has a coinciding rotary
motion with the pulley, 410 which drives the spindle-drum, and when the shipper-
rod, 34, is moved to the left, as above described, the shaft, 67, and its connected
parts, is freed to be thrown upward as described, bringing the worm-gear, 69, into
engagement with the worm, 70, which worm-gear then has a limited rotary
movement according to the amount of twist which it is desired to put into the yarn,

page_text: and its said limited rotary movement is regulated by pins, of, and o³, placed in holes
in said worm-gear, as shown in Figure 7, one of which pins, o³, as the gear is rotated,
is brought against the arm, o³, on the collar, 68, causing the latter and its arm, o², to
swing, thus carrying the last-named arm away from over the yoke which holds the
pin, 415, in engagement with the shipper-rod, 34, thereby letting the latter be moved
a certain distance to the right by the spring, 95, and so stopping the pulley, 410,
which drives the spindles. The said limited rotary motion of the worm-gear, 69, in
one direction, that is to say reversely to that in which the worm, 70, turns it, is
imparted thereto when said gear and worm are disengaged, by the weight, 51, which
is suspended on the end of a cord, (see Figures 2 and 6) which is attached to said
pulley, 220, on the shaft, 67. The said cord passes over a pulley, 49, on the girder, 20,
as seen in Figure 6.
In Figure 36, the position of the pin, o, is clearly shown in engagement with the
said arm, o³, as it is after the weight has rotated the gear, 69, backward, and ready
for a re-engagement with said gear prior to the next ascent of the carriage.
The rotary motion of the worm-gear, 69, by the worm, 70, whereby the pin, 25, is
brought into engagement with the arm, o³, on collar, 68, takes place while the
carriage is moving upward, and at the end of said movement, or when the yarn has
received sufficient twist, pin, o³, strikes said arm, o³, and releases the said yoke which
holds pin, 415, thereby disengaging it from the shipper-rod, 34, and stopping the
spindles as above described.
The said pin, o, is adapted to be placed in any of the several pin-holes shown in the
side of the gear, 69, in order to allow the latter more or less rotary motion before
the spindles are stopped, in order to regulate the twist of the yarn.
As has heretofore been described, when the carriage moves upward, the engagement
of the ratchet-gears, 466, with the racks, at each end of the carriage, causes the proper
operation of the roving-spools and delivery rollers whereby the rovings are delivered
to the spindles.
While the twist is being given to the yarn as aforesaid, the clutches, 230 and 225,
are in engagement, (see Figure 28,) causing the shaft, 11, and the scroll, 138, thereon
to be rotated in an opposite direction to that above described when the yarn was
wound onto the bobbins by the downward movement of the weight, 294. The
engagement of the said clutches serves to cause the scroll-pulley, 138, to rotate and
again raise said weight to an elevated position.
As heretofore stated, the descent of said weight, 294, through its connection with
the scroll-pulley, 138, and the shaft, 11, serves to wind the yarn onto the bobbins
while the carriage descends.
In order to preserve a constant, uniform tension on the yarn while the latter is
being wound on the bobbin, the below-described devices are provided and co-operate
with said weight to effect said result.
When the said weight, 294, is at its elevated position, the distance of the tangent-
point of the rope, 172, on the scroll-pulley, 138, from the axial line of the latter hears
à constant ratio to the distance of the tangent-point of the yarn from the axis of the
spindle, and this ratio is maintained during the descent of the carriage while the
yarn is being wound on to the bobbin.
The said ratio is kept constant by varying the said tangent-point of the rope, 172,
on the scroll-pulley, by winding more or less of said rope thereon.
Referring to Figures 4, 27, 28 and 29, and for further details to Figures 18 to 22,
inclusive. A shaft, 448, is hung in suitable bearings, 227 and 209, on standards fixed
to the bed-plate of the machine.
On said shaft is fixed a gear, 211, and a ratchet-wheel 222, by the side of said
gear. On said shaft, 448, by the side of said ratchet-wheel, is located an elbow-
lever 224, which is hung loosely on said shaft. The said gear ratchet-wheel and
elbow-lever, and other parts connected therewith are shown in side elevation in
Figures 18 and 19, each of said Figures showing said elbow-lever in different
positions. The said ratchet-wheel, 222, a segment of which is shown in Figure 22,
has formed therein, under the face of each tooth, a socket, as shown in dotted lines in

page_text: said Figure and in Figure 19. The said elbow-lever, 224, has one arm extending by
the side of the rim of the gear, 211, on which rim are two lateral projections, o³,
and o³, against each of which the said elbow-lever arm strikes to limit the vibratory
motion of said lever on the shaft, 448. On the opposite arm of said elbow-lever and
near the end thereof are pivoted on a bolt, of, which passes transversely through said
arm, a lever, 223, whose outer end projects beyond the periphery of the gear, 211,
and whose lower end extends towards the shaft, 448, and has an engagement with the
free end of a spring, 437, which is secured to the side of the first-named arm of said
elbow-lever.
Said lever, 223, has a pin, 449, in its side which extends into a notch in the end of
the arm of the elbow-lever on which said lever is pivoted, and limits the vibratory
motion of the lever to the length of said notch, Figure 18, showing said pin at one
end of said notch and Figure 19, showing it at the other.
Two pawls, 359 and 361, whose inner ends are halved together as shown in
Figure 21, (which is a plan view looking from shaft, 448, of the parts which are
pivoted on said arm with the lever, 223, and a section of the arm) are likewise pivoted
on said arm in the plane of said ratchet-wheel, 222, and their outer ends are adapted
The said
to engage independently of each other with the teeth of said wheel.
pawl, 361, has a lip, s2, (see Figure 22) thereon which enters said socket in the face
of the teeth of the ratchet-wheel in order to prevent the elbow-lever from taking a
backward motion. Each of said pawls has a pin in its side, indicated by, 439 and 440,
which pins are adapted to engage with a notch in the opposite edges of the lever, 223,
as shown in Figures 18 and 19.
A saddle-spring, o7, shown in dotted lines in said last-named Figures, and in plan
view in Figure 21, is secured by a bolt to the underside of the head of the said
bolt, o, and its ends extend laterally over, and bear upon the said pins in the sides
of the pawls, 361 and 359, whereby the ends of the latter are made to engage with
said ratchet-wheel. Figure 20, is a side elevation on one of said pawls.
The operation of the above-described devices, in connection with the shaft, 11,
whereby more or less of said rope is wound on the scroll-pulley, 138, is as follows:
While shaft, 11, rotates to wind the rope on said scroll-pulley, the gear, 211, is
given a rotary motion by its connection with said shaft by means of the gear, 55,
(Figures 18, 19, 28 and 29) in the direction indicated by the arrows on Figures 18
and 19.
Figure 18, shows the position of the parts after the spring, 438, has been depressed
by the pressure against it of the lever, 223, as below described, the rope, 172 being
tangent to the scroll, 138, in the proper position for winding the yarn on to an empty
bobbin, as shown in Figure 25. In this position one arm of the elbow-lever, 224, is
in contact with the projections, o8, on the gear, 211.
At the end of each successive winding of the rope on the scroll-pulley after an
empty set of bobbins has been put on the spindles, the tangent point of the rope on
the scroll must rise in order to make the tension in winding the yarn correspond to
the shape of the newly forming yarn-cones on the bobbins.
This tangent-point is made to rise by the pawl, 359, and parts attached therewith
on lever, 224, gaining one tooth on ratchet-wheel, 222, in each successive winding of
the rope on the scroll until the yarn-cone at the base of the bobbins is wholly formed,
at which time one arm of the elbow-lever, 224, is in contact with the projection, o³,
on gear, 211, and prevents further movement of the pawl, 359, on the ratchet-
wheel, 222. Each time the scroll is wound after the above contact of said arm and
projection the rope has a tangent-point on said scroll, as shown in Figure 26. Each
tooth on the ratchet-wheel, 222, which has been occupied by the pawl, 359, corre-
sponds to a tangent-point on the scroll when the scroll is wound. The number of the
teeth acted on by the pawl, 359, varies with the size of the yarn spun, as each tooth
represents one descent of the carriage.
On Figure 31, are shown at the base of the bobbin, three pending dotted lines
numbered respectively, 1, 2, 3. On the scroll in Figure 25, are shown three points
indicated by, 1, 2, 3, at which the rope, 172, starts from to wind the first three

page_text: layers of yarn, 1, 2, 3, on the bobbin, which are indicated by said Figures in
Figure 31. On the ratchet-wheel, 222, Figure 18, are shown opposite three teeth
thereon the figures 1, 2, 3, which indicate the teeth which the pawl, 359, engages
with when the winding motion of the scroll is stopped so as to leave the rope
tangent at the points marked 1, 2, 3, thereon.
As the winding continues the gear, 211, and the ratchet-wheel, 222, are rotated in
the direction above described, and the elbow-lever and parts attached thereto rotate
with said gear in consequence of the engagement of the pawl, 361, with the
ratchet-wheel, 222.
When in the course of the rotation of said gear the end of the lever, 223,
comes in contact with the spring, 438, the resistance of the latter against the end
of said lever, causes the lever, 223, to swing on its pivot against the action of the
spring, 437, and to move its notched edge away from under the pin, 439, thereby
letting the end of the pawl, 359, be swung by the end of the saddle-spring on to
the point of one of the teeth of said ratchet-wheel. The said spring, 438, still
continues to press against the outer end of the lever, 223, and causing its notched
edge to swing against the pin, 440, in the pawl, 361, thereby lifting the end of
said pawl off from the ratchet-wheel, against the resistance of said saddle-spring,
and therefore the end of the pawl, 359, only, is engaged with the ratchet wheel, by
the movement of the latter since said pawl first dropped onto it, its point being
brought to the base of one of the ratchet-teeth.
By the above described alternate engagement of said pawls with the ratchet-
wheel, the latter, and the gear, 211, are permitted to advance to the extent of the
length of one of the teeth of the ratchet-wheel, for it should be borne in mind
that the pawl, 359, first struck one of said teeth near its end, and the wheel then
turned, when freed by the pawl, 361, to bring the end of the pawl, 359, to the base
of said tooth.
The gear, 211, and the said ratchet continuing their rotary motion, the lever, 223,
is still farther swung on its pivot until the pin, 449, on said lever is brought against
the end of said notch in the end of the elbow-lever, when the lever, 223, can swing
no more and its movement against the spring, 438, causes the hooked end of the
latter to be swung out of engagement with the hook on the collar, 208, thereby
letting the shaft, 358, move end wise as above described, and carry with it the clutch
arm, 231. The said clutch-arm engages, as aforesaid, with the clutch, 230, and con-
sequently removes the latter from engagement with clutch, 225, and thereby stops
shaft 11, and the winding of the rope on the scroll-pulley, 138 at the desired point.
After the disengagement of said hooks, the spring, 206, on the rod, 358, moves the
latter and said clutch-arm to the position shown in Figures 28 and 29.
When the yarn is wound onto the bobbins, the gear, 211, is turned in a contrary
direction from that indicated by the arrow at the periphery thereof, and by said
backward rotary motion the elbow-lever, owing to the engagement of the pawi, 361,
with the ratchet-wheel, is carried around with the gear, removing the end of lever, 223,
from the spring, 438.
The above-mentioned action of the gear, 211, and elbow-lever, 224, relative to the
rotary movements of said gear in both directions is entirely automatic, but to leave
the rope wound only on the hub of the scroll-pulley, 138, when a new set of bobbins
is put on the spindles, thereby having said rope wound on a part of the pulley whose
diameter corresponds, proportionately, to that of the barrel of the bobbin when the
first winding begins, after putting on said empty bobbins, the elbow-lever is turned
by the operator to the position shown in Figure 18, bringing the end of one arm of
said lever against the projection, o³, on the gear, 211, and lever, 223, is forced against
the spring, 438, to disconnect it, and to prevent one winding-motion of the scroll
from taking place at the first ascent of the carriage after doffing. After said adjust-
ment by the operator, the winding, and the ratchet-movements of said elbow-lever
take place automatically, as above described.
As means for stopping the carriage when it reaches its highest point by freeing
the shipper-rod, 34, so as to let spring, 95, move it a certain distance to the right
C

page_text: thereby disengaging the clutch, 9, from clutch, 25, the vertical rod, 132, is located
with its lower end in a steady block, 251, on the bed-plate, 1, and extends upward to
the top of the frame over the carriage, its upper end having a support in an arm
attached to the side of the frame (see Figure 41). Said rod has a collar, 124, thereon
near its lower end, with which the long arm of an elbow-lever, 123, engages, the
short arm of said lever engaging with a collar, 400, on the stop-pin, 299, (see
Figure 32) heretofore described as engaging with the shipper-rod, 34, to hold it in a
shipped position. The said rod, 132, has a second collar, s, thereon near its upper
end, with which an arm, st, on one of the frame-plates of the machine (see Figure 41)
engages when the carriage arrives at its highest point, thereby lifting said rod, and
giving to said elbow-lever, 123, such a vibratory motion as serves to draw said
pin, 399, out of engagement with the shipper-rod, 34, letting it slide as above set
forth, until it is stopped by pin, 415, as above described, (see Figures 8 and 37) and
move said clutch, 9, thereby stopping the gear, 35, which operates the above-described
carriage-elevating mechanism.
The above-described sliding movement of the shipper-rod, 34, moves the collar, 118,
thercon against the arm, 287, of the heretofore described elbow-lever (see Figures 5
and 8) thereby causing the rod, 114, to be lifted slightly and the shaft, 18, to be
slightly rocked, together with its attached arms, above described.
After the twisting of the yarn is completed, the spindles are stopped by a further
movement of the shipping-rod, 34, to the right by the disengagement of the pin, 415,
as above-described, from the said shipper-rod, thus allowing the spring, 95, to move
said rod, until it is again stopped by the pin, 401 (see Figures 8 and 32). This last
movement disengages the clutch, 59, from clutch, 409, thus stopping the spindles.
This last-described sliding movement of the shipper-rod, 34, rocks the said shaft, 18,
still more, and carries the end of the arm, 179, thereon (see Figure 5) against the
catch-block, a, on the bar, 178, to an operative position preparatory to subsequent
movements of the parts governing the action of the pawl, 143, as heretofore
described.
During the above-described action of the machine in spinning the yarn, the friction-
pulley, 283, (see Figures 2 and 5) on the drum-shaft, 82, is disconnected from said
shaft. The last-described movement of the shipper-rod, 34, causes the connection of
the pulley, 283, with the drum-shaft, in the manner below described, thus stopping
the spindle-drums and actuating the backing-off motion in the following manner.
The drum-shaft, 82, and drums are rotating at full speed when the friction-
pulley, 283, is brought into engagement with said shaft as below described, and thus
the tendency of said pulley is to rotate with said shaft, but it being connected with the
heretofore-described pulley, 282, by belt, 162, the momentum of the drum-shaft causes
said pulley, 282, to revolve a fraction of a revolution against the force of the coil-
springs, 160, on each side of said pulley, until the said arms, e³, on the hubs to which
the said springs are connected, and the stop-projections, e², on the pulley, 282, come
in contact, when the said pulley and the drum-shaft stop rotating. The instant the
said pulley and shaft stop, the springs, 160, revolve said shaft and pulley in opposite
directions, the latter being stopped against the opposite side of said projections, e²,
from whence the pulley started as aforesaid. Said backing motion of the drum-shaft
by the action of the said springs, 160, unwinds a short length of yarn from the
spindles preparatory to the said falling down of the building wires before the descent
of the carriage, as shown in Figures 5, 23 and 24.
On the bed-plate of the machine back of the shipping-rod, 34, is a hook-lever, 290,
having a U-shaped opening in its free end, its opposite end being pivoted to a
block, 289, (see Figures 34 and 35, the last being in plan view, and the former a side
elevation). Said hook-lever extends in front of the lower end of a vertical, rocking
shipping-rod, 10, having an arm, 288, thereon whose free end is adapted to swing
into and out of the open end of said lever, 290, in a horizontal plane. Said arm, 288,
has thereon an upwardly projecting pin, 396, which is capable of an end wise motion
vertically against the end of a spring, 397, under the arm. A spring, 292, is located
under said hook-lever, 290, to hold its free end yieldingly upward. On said shipping-

page_text: rod, 34, is fixed a collar, 118, having thereon a horizontal bunter-arm, 395, whose end
is adapted to strike the said arm, 288, near its end when the rod, 34, is moved to the
left, and turn or rock the said rod, 10, correspondingly.
On said rocking vertical shipper-rod, 10, is fixed an arm 12, which has a forked
engagement with a groove around a sliding cone-shaped collar, 13, on the drum-
shaft, 82, (see Figures 2 and 5).
The relative positions of the arm, 288, and hook-lever, 290, shown in Figures 34
and 35, are those which they occupy when the said friction-pulley, 283, is connected
with the drum-shaft, 82, (see Figure 2) the sliding, conical collar, 13, being then
forced between the arms of said pulley by the spring, 14, as shown in said last-named
Figure. In Figure 5, is clearly shown said rod, 10, and the shipper-arm, 12, thereon
which engages with said sliding cone.
As above set forth, the said shipper-rod, 34, is moved to the left when the carriage
reaches the bottom, the said movement of the shipper-rod to the left brings the end of
said bunter-arm, 395, against the arm, 288, on rod, 10, and carries the end of said
arm into the opening in the end of the lever, 290, until the pin, 396, thereon is
depressed and finally is thrown upward behind the hook shown on the upper side of
said opening, the bunter-arm, 395, resting on the lower side of said opening in the
hook-lever and preventing spring, 292, from raising said lever and disengaging its
hook from the pin, 396, in the arm, 288. The first movement of the shipper-rod, 34,
to the right, draws said bunter-arm along the lower side of said opening in the
lever, 290, but does not move it off from the same. The second movement of said rod, 34,
to the right draws the end of the bunter-arm along on said lever, but it does not clear
the end thereof until after the above-described clutches, 59 and 409, connected with.
the main shaft, 188, have become disengaged. The moment said bunter-arm clears
the end of said lever, 290, the spring, 292, swings the end of said lever upward freeing
it from the pin, 396, on the arm, 288, thereby leaving the shipper-rod, 10, free and
removing all obstacles to the action of the spring, 14, on the drum-shaft, 82, to slide
the conical collar into engagement with the arms of the friction-pulley, 283, and
connecting it with said drum-shaft, thus effecting the "backing-off motion" and the
stopping of the drums as above described.
The above-mentioned friction-pulley, 283, is connected with the drum-shaft only
during the "backing off" motion and the winding of the yarn on the bobbins. It is
disconnected from said shaft when the carriage nears the bottom by the aforesaid
movement of the shipper-rod, 34, to the left, as described.
Reference has heretofore been made to the function of the pin, 401 (see Figure 8)
in retaining said shipper-rod, 34, in a certain position. Said pin, and its operating
mechanism, is shown in side elevation in Figure 32, the same mechanism is shown in
front view and partly in section in Figures 7 and 8, respectively. The pin, 401, is
supported in a bearing-block, 122, fixed to the bed-plate 1, and an arm, 125, reaching
over said block. A collar 402, is fixed on the pin, 401, and a spring, 403, between
said collar and the arm above it serves to drive the pin downward against the shipper-
rod, 34, which runs through said block under said pin, and to cause the lower end of
the latter to engage in a slot in the upper end of said rod, (see Figure 8).
A short shaft, 398, having its lower end more or less pointed, is hung in a projection
on the front side of said block, 122, and in the end of said arm, 125, and on its upper
end is a grooved-pulley as shown, on which is secured a crown-gear, 127. A cord, 171,
has one end attached to said grooved pulley and is wound around the latter and carried
under a guide-pulley, 128, and thence upward over a pulley, 173, on the girder, 20
(see Figure 2) and has on its pending ond a weight, 174. Said shaft 398, has fixed
thereon also a disk, 131, having a reciprocally rotating movement, and having a cam-
projection, v³, on its upper side, which is adapted to engage with the said collar on the
pin, 401, and lift the latter. Figure 33, is a plan view of said disk, 131, in which are
a series of pin-holes, in one of which is a pin, v, which may be placed in either of said
holos. The said crown-gear is located under the main shaft, 188, and in such position
that it may be engaged with a worm, 126, on the sleeve, 113, on said shaft. The
rotation of the disk, 131, by the engagement of said crown-wheel and worm brings

page_text: the projection, ³, under the collar, 402, to lift pin, 401. The separation of said
crown-wheel and worm, leaves the shaft, 396, and the disk, 131, free to be rotated in
the opposite direction by the action of said weight, 174, until the pin, v¹, strikes the
side of said collar, 402, bringing the parts to the position shown in Figure 32.
The operation of the last-described devices in connection with the shipper-rod, 34,
and by the second movement of the latter to the right, before described, is as
follows:
To a collar, 119, on said rod, 34, is attached an arm, 120, extending under the
lower end of said shaft, 398, the upper edge of said arm having an upward projection
with a depression each side of it.
When the shipper-rod, 34, is at its extreme left position the pin, 401, is pressed into
a slot in the rod, 34, shown near said pin in Figure 8, and the lower end of shaft, 398,
rests on arm, 120, on the depressed part thereof at the right of the said projection
thereon. The first movement of rod, 34, to the right brings the end of shaft, 398,
close to the end of said projection. The second movement of said rod brings said
projection under the end of shaft, 398, thereby raising the latter and its attached parts
and engaging the crown-gear, 127, and the worm, 126, thereby rotating the disk, 131,
and raising the pin, 401. The pin, 401, holds the rod, 34, in the position it takes
after its second movement to the right, and holds it in that position until the pin is
withdrawn as below described.
While rod, 34, is held by pin, 401, as just described, the building-wire arms have
the positions shown in Figure 4.
.
The said cam-projection, v³, on the disk, 131, has its upper edge inclined as shown,
and when it acts under the collar, 402, on pin, 401, it withdraws the latter gradually
from said slot in the shipper-rod, 34.
After pin, 401, has been partly withdrawn from said slot so as to be engaged with
the off-set at its end shown in Figure 50, thereby letting rod, 34, slide slightly to the
right, and far enough to draw the end of arm, 341, (see Figure 14) from under the
collar, f, on the tube, 38, whereby the latter is let drop so that the point of rod 106,
strikes the edge of the cam, 340. This downward movement of rods, 38 and 106,
rocks the shaft, 47, (see Figure 6) and consequently swings the building-wire arms so
that the wires are brought to their proper position at the base of the yarn-cones, ready
for the descent of the carriage.
The withdrawing of the pin, 401, from said slot in rod, 34, continues, and when
fully withdrawn the rod, 34, is by the spring, 95, thereon given its final movement to
the right, which movement still farther lifts the rod, 114, thereby rocking the shaft, 18,
and its said attached parts and causing the bar, 178, to be pushed endwise and the
pawl, 143, disengaged from the ratchet-wheel, 144, thus leaving the weight, 294, free
to act as aforesaid on the spindle-drums to wind the yarn on the bobbins while the
carriage descends.
Furthermore, said final movement of the rod, 34, engages the clutches, 59 and 25,
on the main shaft, 188, and permits the unwinding of the scrolls, 190 and 205,
(Figure 6) thus allowing the carriage to descend.
The foregoing description of the operation of the mule-spinner herein shown and
described embraces the action of the various parts thereof while the carriage descends
and rises again to the top of the machine and is brought to the position from whence
it started.
On each side of the machine and running from end to end thereof is hung a shipper-
rod, 19 (see Figures 1, 5 and 38). A vibratory lever, 170, is pivoted under the said
girder, 20, and has its ends engaging between collars, 169 and 168, on each of said
rods, 19. Said lever, 170, extends across the above-referred-to shaft, 18, and has a
pivotal connection with a sliding clutch, 167, which is keyed on said shaft, and slides
thereon. A clutch, 166, having an arm thereon in which shaft, 18, rocks freely is
hung on said shaft, and the end of said arm is curved and extends laterally at the side
of the machine, and has a bar, 115, pivotally connected thereto and with an arm, 117,
at the bed-plate which is fixed on a rock-shaft, 121. A forked arm, 131, fixed on said
shaft, 121, engages with a cone-shaped sliding collar, 286, on the above-referred-to

page_text: driving shaft of the machine (see Figures 2 and 4). As above described a friction
driving-pulley, 136, of ordinary construction, is hung on the shaft, 14, having lever
arms as shown, hung therein and projecting laterally therefrom and bearing on said
conical collar, 286. The movement of said collar against said arms causes the shaft on
which the pulley is hung to rotate with the pulley, and the movement of the said collar
in the opposite direction frees the pulley from the shaft so that the shaft no longer
rotates. The friction-pulley heretofore referred to on the drum-shaft, 82, is of like
construction.
The said forked arm, 139, is fixed on a rock-shaft, 121, at the base of the machine,
and an arm, 150, fixed on said shaft has a spring, 151, connected to its end which
serves to engage the collar, 286, with the driving pulley when the said clutches, 166
and 167, are disengaged.
Either of the said shipper-rods, 19, is in a convenient position to be grasped at any
point on either side of the machine to engage said clutches, 167 and 166, in order
that the carriage may be stopped at its lowest point when in moving it strikes the
said plungers, 263 and 221, and thereby rocks shaft, 18, and through the latter causes
the friction collar of said driving pulley to be moved therefrom, and the action of the
machine to be stopped.
To provide for operating the said conical friction collar 286, on the driving shaft, 141,
in order to stop the machine at any moment and then to start it if desired, a hand
shipper-rod, 180, (see Figures 2 and 5) has its lower end secured in a collar on said
shaft, 121, adjoining the collar, 139, to which is attached the aforesaid forked arm
which engages with said friction collar. The said collar to which the shipper-rod, 180,
is connected has a lip attachment, or connection, with the end of said collar, 139, so
that when the shipper-rod, 180, is moved from the position shown in Figure 5 (where
the end of it is shown broken off) towards the side of the machine, the arm, 139, has
a similar motion and draws the collar, 286, away from the arms of the friction-pulley
thereby causing the machine to be stopped. An arm, 147, is bolted to the side of the
machine and extends laterally by the side of the shipper-lever, 180, and has a notch
in its edge, as shown, with which said lever engages when swung up to stop the machine.
When the shipper-lever is disengaged from said notch in the arm, 147, the aforesaid
spring, 151, serves to throw the friction-collar, 286, again in engagement with the
arms of the friction-pulley and start the machine.
