COMPLETE SPECIFICATION.
Improvements in Spinning, Twisting, and like Machinery.
I, AUGUST RUDOLF ERBSLÖH, Merchant, of 280, Washington Avenue,
Brooklyn, in the County of Kings, and State of New York, United States of
America, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My present invention relates to spinning jennies, and has for its object to produce
a flyer which may be driven at a very high rate of speed.
To this end my invention consists in a flyer consisting of a rotary head, flyer
rods secured thereto by one end and having their free ends received in a groove in
the face of a stationary ring, and also in further details of construction hereinafter
described and more particularly pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a side view of a jenny having my invention applied thereto.
Figure 2 is an end view of the same. Figure 3 is a section, on line 33 Figure 1,
looking in the direction of the arrow.
Figure 4 is an enlarged broken-away detail sectional view of a form of my
improved flyer and other parts presently to be described.
Figure 5 is a section, on line 5-5 Figure 4.
Figure 6 is a front view of the stop mechanism for the jenny; Figure 7 is a
side view of the same, partly broken away.
In jeunies as hitherto constructed, it has been customary to unite two revolving
heads by flyer-rods of considerable length in order to allow for the travel.of the
bobbin between the heads. This bobbin has been hitherto carried by a long
traverse tube extending through one of the heads. These long flyer-rods have
been found to be objectionable owing to the fact that when the flyer was revolved
at a high rate of speed, the rods would bulge outwardly under the influence of
centrifugal force, thereby defeating the object of exactness in adjusting the parts
and straining the parts and interfering with the proper twisting and laying action
of the flyer. By my present invention 1am enabled to shorten these flyer-rods
about oue-half, as in my said machine it is only necessary that these flyer-rods
be about the length of the bobbin to be wound. This shortening of the flyer-
rods enables the flyer to be driven at a very high rate of speed without danger of
strain or breakage, or the attendant defects of long flyer-rods.
This I accomplish in the following,manner:
Referring now to Figures 1 and 4; A is the usual left-hand head of the flyer,
in which may be the usual dies or contrivances customary in such machines, but
which, however, are not shown, since they form no part of the present invention.
This left-hand head instead of being united by means of flyer-rods with a similar
head, is provided according to the present invention with flyer-rods a, upon which
may be the usual guide rollers b, the ends of said flyer-rods being entered into an
annular recess c of a stationary ring C which is adjustably supported on the
frame D of the inachine by the screws operating in slots Z Z respectively,
or any other well-known means. The free ends of these flyer-rods which are
entered into the groove in the stationary ring are wholly disconnected from each
other and are shown as provided with rollers B, but the said rollers may be omitted,
if desired.

page_text: The bobbin E is carried by the tubular shaft F (through which extends the
rod K) which also carries the pulley G, and has its bearings on opposite sides of
said pulley, said bearings projecting from a carriage or slide H that is supported on
a longitudinal stationary rail I pertaining to the framework of the machine. This
stationary rail extends into contact with and is fastened to the stationary ring C
and assists in properly bracing it.
The traversing motion may be imparted to the carriage H supporting the pulley G
that rotates the bobbin, in any suitable manner.
I have shown one means consisting of the rack d connected with the carriage H.
Gearing with this rack d is a pinion e carried on the end of a shaft stepped in
a bracket g on the frame of the machine, and extending loosely through a guide h
which permits the shaft to oscillate around its step as a center. Mounted on the
shaft is a gear i which meshes with a worm suitably driven from the shaft k
of the drum. The pulley G is belted to the drum I, and the rotation of the
drum will serve to rotate the bobbin, and at the same time give it a traverse
motion by means of the rack. d and pinion e. The pinion e as it rotates will
pass first on one side and then on the other of the row of pins d' of the rack, and
will give the rack, carriage and bobbin a longitudinal to and fro motion as the
bobbin is revolved.
The coupling L (Fig. 4) which connects the bobbin with the rotary.shaft is
adjustable on said shaft as shown, so that on starting the machine, if the traversing
contrivance has not been exactly adjusted as it ought to be, the attendant may,
by slightly adjusting this coupling, cause the position of the bobbin at all times
to conform to the position of the traversing mechanism. To this end the
tubular shaft which enters the coupling should never extend fully through the
coupling.
The operation of the machine is as follows: The slivers & come into the
machine from the left, and are taken from a chain (not shown), and through
nippers (not shown) in the usual. way to the flyer, where they are twisted into a
strandt and laid onto the bobbin, the bobbin being given a traverse motion
through the ring by the traverse mechanism. Instead of operating on slivers, the
machine is equally applicable to the twisting of strands that are taken from reels
through a perforated plate in the usual manner, for the purpose of doubling the
strands.
In order to provide for the stoppage of the machine should any breakage of the
slivers or strands occur, I arrange a pivoted lever o between the nippers and the
flyer, at some distance to one side of the path of the slivers or strands. This lever
consists of two parts qv held frictionally together by a spring, to so as to be
positively extensible and contractible, and to enable the parts to remain in any
position to which they may be extended, as shown in Figs. 6 and 7. In this
respect the stop lever differs from stop levers heretofore used, of which there are
some that are not at all extensible,. while others that are extensible are provided
with extending springs that will always hold the said lever in the extended position,
unless it is held by hand in the contracted position. From the stop lever o a cord u
passes around pulleys y to any suitable form of belt shipper Z or other suitable
arrangement for stopping the machine.
The stop lever o is left in the contracted position while the slivers or strands are
adjusted in the machine, and is then swung over to the opposite side of the
adjusted slivers or strands, and extended so that it shall rest against the said
slivers or strands, holding the shipping lever retracted, and the belt M. on the
tight pulley N as long as the slivers or strands remain unbroken. This pulley N
communicates motion through the gearing mn to the shaft & that operates the
parts, as above described. The moment the slivers break, the lever will fall past
the path of the slivers or strands and will thereby permit a spring or a weight 2¹
to shift the shipping lever M to the loose pulley O, thus stopping the machine.
While adjusting the slivers in the machine prior to starting it, the stop-lever
is intended to remain in the contracted position, and can after the adjustment

page_text: of the slivers &c. be brought past the slivers and then extended with great
convenience.
My invention is equally applicable to rope forming machines, etc., and by the
term jenny I wish to embrace all analogous machinery.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is: :-
1. In a flyer, the combination of a rotary head with flyer-rods that are connected
at one end to said rotary head, a stationary ring parallel to said head, said stationary
ring having a groove in its face, into which groove the loose ends of said flyer-rods
enter, as and for the purpose specified.
2. In a flyer, the combination of a rotary head with flyer-rods that are connected
at one end to said rotary head, a stationary ring parallel to said head, said stationary
ring having a groove in its face into which groove the loose ends of said flyer-rods
enter, and means substantially as described for adjusting the stationary ring in a
vertical plane, and for holding the same in its adjusted position, as and for the
purpose specified.
3. The combination with a jenny and mechanism for operating the same, of a two
part extensible and contractible stop lever having means for holding its parts
together frictionally so that they will remain either in the contracted or extended
position, and a connection between said stop lever and the mechanism for operating
the jenny, as and for the purposes set forth.
