Improvements in Twisting Machines for Cordage, Yarn, and
the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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 twisting-machines for twisting and laying cordage, yarn
and the like, and the invention relates to certain novel constructions and
combinations of parts hereinafter described.
In the accompanying drawings,
Figure 1 is a front elevation of a twisting-machine embodying my invention,
portions of the frame and machine being represented as broken out.
Figure 2 is a side elevation with portions of the frame represented as broken out
the better to illustrate the invention.
Figure 3 is a front elevation partly in section to an enlarged scale showing
portions of my invention in detail.
Figure 4 is a horizontal section on line x, x, Figure 3.
Figure 5 is a horizontal section on line y, y, Figure 3.
Figure 6 is an enlarged detail view in vertical section showing the shape of the
weighted disks, which support the disks.
Figure 7 is an enlarged detail in elevation showing the arrangement of the guide-
wires and adjacent parts, and
Figure 8 is a horizontal section on line z z, Figure 3.
Similar letters of reference indicate corresponding parts in all the figures of the
drawings.
A A represent upright portions of the frame, and A. A" represent respectively
upper and lower horizontal portions thereof. B B are hollow fliers (often termed
spindles) arranged preferably in groups of three, as shown in the drawings,
(see Figures 4 and 5).
Each of these fliers is provided with a series of openings B' (Figures 1, 2 and 3)
arranged one above another, and all on the same side of the flier.
Within each flier and behind each opening, is a spool & which rests on a disk or
horizontal partition C, (see Figure 6) said disk or partition being very much
thickened or weighted at its front portion C¹, (see Figures 3 and 6) that is, the
portion directly to the rear of or within the portions B of the flier. The weighted
portions C¹ therefore of the disks C are all on the side of the flier which is provided
with the openings B', and serve to balance the flier by providing sufficient extra
weight on that side to counterbalance the weight of the other or closed side.
The shape of these portions C¹ is shown by dotted lines in Figure 5. Similar
weights or masses of metal are provided at the closed upper and lower
ends B B of the fliers, the shape of said weights being shown at C" in
Figures 3 and 8. The lower portion of each flier is provided with a projecting
shaft or spindle D which is supported in a step D' screwed or otherwise secured
into and sustained by the lower plate D". Between the lower end of the spindle D
and that of the opening in the step D' into which said spindle extends, is a hall D,
say a thirty-second of an inch smaller in diameter than the opening in which it is
placed. The flier, in rotating, turns on this ball which turns within its chamber,
thus constituting two centers and providing an excellent oil-chamber. See
Figure 3.

page_text: The plate D in which are bearings for all three of the fliers, is rigidly secured
to or integral with the driving spindle d whose lower end d', rests in a step d¹¹
upon a ball d, said step being supported by the portion A" of the frame
(Figures 1 and 3).
The arrangement of this ball is exactly similar to that above described of the
ball D¹¹¹
E is the driving-pulley to which power is applied, the said driving-pulley being
fast on the shaft E.
There being two sets of fliers, one set being exactly behind the other, as shown
in Figure 2, it is necessary that there should be two driving shafts one of which is
connected with the other. The driving shaft E' has fast upon it the pulley El
connected by cross-belts e" with the driving pulley e fast on the shaft e¹ (Figures 1
and 2). The shafts E' and e¹ have their bearings in uprights a extending from the
portion A of the frame. Each of these shafts E' and 'e' has fast upon it a
pulley F, and each pulley F is connected by a belt F' with the horizontal pulley F"
fast on the driving spindle d of the set of fliers next the said pulley F". Thus
rotary motion is applied to the spindle d around which the fliers revolve by means
of a plate D and an upper plate described below.
.
The lower or solid ends B of the fliers are provided each with cones or
pulleys, and a cord or belt f¹ is passed around said cones or pulleys in the manner
shown in Figure 4. The ends of this cord f1 are secured at f" to the outer end of
a coiled spring g similar to the main spring of a watch, the inner end of the said
spring being secured to the drum g (Figures 1, 2 and 4). This drum, which is
provided with an annular serrated thumb-piece ", is arranged upon an upright
stud H supported by an upright H¹ extending from a bracket a secured to the
portion A of the frame. The lower edge of the drum g' is provided with ratchet
teeth as shown in Figures 1 and 2, which engage similar ratchet teeth in a drum or
head H secured rigidly upon the stud H. By means of the cord ", spring y and
ratchet drums above named, the fliers are individually rotated as they revolve
around the spindle d, while the tension of the cord f¹ not only accommodates itself
to the exigencies of the case but can be regulated by rotating the ratchet drum gl
upon the under drum or head H¹¹.
In order to prevent the fliers from spreading by centrifugal force, bands h, (not
new in this invention) may be centrally applied thereto.
Each flier is provided with the usual solid or dead spindle I. This spindle
extends from the upper end of the flier through the bobbins and disks C into the
lower end B. Between the lower end of this dead spindle and its sent is a spiral
spring (Figure 3). The upper ends B of the fliers have their bearings in the
plates rigid upon the spindle_d. These upper ends are provided with the
usual passages J¹ (Figure 3). The upper end of each dead spindle I has rigidly
secured to it a guide-wire J bent into the coiled shape shown in Figure 7, said
guide-wire being secured to one side of the centre of the spindle I so as to bring
its coiled portion over such centre. The strands pass from the bobbins throngh
suitable openings in the fliers in the usual manner around the screws or pins i
and through the passages J up into and through the guide-wires J; thence
they pass through the usual passages in the "laying-up" spindle d and up
through the portion A' of the frame. By means of this guide-wire in which
the thread winds, in case it is desired to remove and replace a bobbin, the yarn
is untwisted, the dead spindle I withdrawn, the bobbin removed and another put
in its place, the spindle I dropped into its former position and the yarn twisted in
again.
A. hook K (Figure 7) extends up from the upper end of each flier, and a
projection K' extends horizontally from the side of the spindle I into engagement
with said hook. In practice the spring I' holds the spindle I up and prevents jar,
and the projection K³, engaging with the hook K, prevents it from moving up or
sidewise.
I prefer to introduce felt K" (Figure 3) between the upper end of the flier and

frequent oiling.
UIT
The yarn S, after passing up through the guide-wire J passes over the whirl or
pulley L (Figure 1) which is loose and free to slide endwise on the tight shaft L'
supported at L" on suitable brackets secured to the frame. The usual adjustable
tension-spring bears against the yarn S between the laying-up spindle d and the
whirl L. From the whirl L, the yarn passes over the cone or series of pulleys N
adjustably secured to the shaft N having its bearings in brackets N" supported by
the frame.
It is understood that the parts L L' L", N N' N", connected with the fliers on
the front of the machine, are exactly duplicated at the rear of the machine for
connection with the rear fliers.
Motion is imparted to the shafts N₁ by means of gear-wheels n fast on said
shafts, said gear-wheels being engaged by the pinions n' fast on the hubs of the
pulleys n which are connected by the cross-belts m with the pulleys m¹ fast on the
driving shafts Ele¹. (See Figures 1 and 2). The pinions n' which are fast
upon the hubs of the pulleys n" are loose upon shafts or pins m¹ which are.
supported by arms P (Figures 2 and 3) whose lower ends are loosely supported by
hubs or boxes P¹ on the driving shafts E¹ e'. These arms P are provided with the
integral extensions R, each of which has a curved slot R' forming an arc of a circle
of which one of the driving shafts E¹ e' is the centre. These slotted arms are
adjustably secured to the frame by means of suitable bolts and nuts. Hence,
if different sized pinions n' are desired to be employed, the pinion in use can be
removed and replaced by, say a larger one, by swinging the arm P by means of the
slotted extension R until the new pinion is in engagement with the gear-wheel n.
The yarn S passes from the cone or pulley N to the reel, which is not new in this
invention, and which consists essentially of the four arms T extending from the
outer ends of the four radial arms or spokes T', one of said arms T being pivoted
at t to its radial arm, which has pivoted to it at t¹ the arm t". These reels are
loose on studs T supported by uprights U secured to the frame. The reels more-
over are rigidly secured to the internal or ring gear-wheels U₁ which are engaged
by the pinions U" fast on the hubs V of the loose pulleys V' which are connected
by belts V with the pulleys W fast on the shafts N'. Thus motion is imparted
to the reel indirectly from the driving shafts.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. The hollow fliers or spindles B provided with openings B₁ for the admission
of the bobbins, and discs C for supporting said bobbins, the said discs being weighted
at C on the side next said openings for the purpose of balancing the fliers,
substantially as described.
2. In a twisting-machine, in combination, the fliers or spindles B provided with
the spindles or axles I) at their lower ends, the steps D supported by the plates D"
and bored out to receive the spindles D, and balls Du interposed between the
lower ends of said spindles D and the bottoms of the holes in the steps, substantially
as described.
3. In a twisting-machine, the combination of the fliers or spindles B provided
with the cones or pulleys f, the band D" around said fliers, the coiled spring g one
end of which is secured to said band and the adjustable drum g' to which the other
end of the spring g is secured, substantially as set forth.
4. In a twisting-machine, the combination of the flier or spindle B provided with
the solid lower end B bored out to receive the end of the dead spindle, the dead
spindle I, and the spring I' interposed between the lower end of the dead spindle
and the end of the hole in which its end lies, substantially as described.
5. In a twisting-machine, in combination, the "laying up" spindle a step d¹
bored out to receive the lower end of said spindle and supported by the frame, and

page_text: the ball interposed between the lower end of said spindle and the bottom of
the hole in which its end lies, substantially as set forth."
6. In a twisting-machine the combination of the reel, the internal or ring gear
wheel U rigidly secured to said wheel pinion U engaging said gear wheel and
mechanisms, substantially as described for communicating motion to the said pinion,
substantially as described.
7. In a twisting-machine the combination of the dead spindle 1, the guide wire .J
secured to the upper end thereof, the hook K, extending up from the flier and the
projection K extending from the dead spindle into engagement with the said
