Improvements in and connected with Fliers for Spinning and the
Manufacture of Cordage.
I, JOHN GOOD, of Far Rockaway, in the City of New York and State of New
York, United States of America, Manufacturer, 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 all such fliers, for the spinning of twine and rope yarns
and for other operations in the manufacture of cordage, as are provided with
attached capstans for the drawing thereinto of the sliver to be spun, or the yarns
to be twisted together. The object of the improvement is to so apply the capstan
to the flier, and to so provide for driving it, as to reduce the amount of centrifugal
force developed in its rotation, and to reduce its wear, and the wear of its im-
mediately associated parts. To these ends, the improvement consists principally
in the placing of the capstan upon the flier concentric therewith, so that the axis
of the one is coincident with the axis of the other; and it further consists in the
combinations hereinafter described and claimed, in which the so placed capstan
is an essential element.
For the purpose of explaining the invention, it is illustrated in the accompany-
ing drawings as applied to a spinning machine of the "jenny" type, that kind of
machine serving as well as any other for that purpose.
Fig. 1 is a side elevation of such parts of the machine as are necessary for the
explanation.
Fig. 2 is a longitudinal view, partly in section, of the flier journal, to which the
concentric capstan is applied, showing also, in part, the means for driving the
capstan.
Fig. 3 is a transverse section in the line 3-3 of Fig. 2.
Fig. 4 is a longitudinal view of an extension piece applied to the flier journal
to carry the capstan.
Figs. 5 and 6 represent, respectively, side and front views of guide pulleys, and
the carrier by which they are attached to the said extension piece.
Similar letters and numerals of reference designate corresponding parts in all
the figures.
A (Fig. 1) is the framing of the machine, on the top of which are arranged the
stationary bearings a a for the journal B₁ of the flier B. In the lower part of said
framing are arranged the bearings C¹ for the shaft C, which is parallel with the
axis of the flier, and which carries the pulley D for driving the
flier, the pulley E for driving the bobbin F, and a third pulley G
for driving the concentric capstan H of the flier. The said shaft C
also carries the endless screw I, which, through an upright shaft J and
bevel gears c, c and d, d, drives the traverse screw K by which the bobbin
carriage F is operated, to produce the reciprocating longitudinal movement of the
bobbin F within the flier.
The parts above referred to, except the concentric capstan H and its driving

page_text: pulley G, are all such as may be found in known machines of the "jenny" type,
and are only represented and herein described to facilitate the practical application
of the invention, which will now be described in detail with reference to Figs. 2,
3, 4, 5, and 6.
The flier journal, designated as a whole by the letter B¹, is made of two pieces b,
and b¹. Of these the piece b, which is immediately connected with the head of
the flier, and fitted to the journal boxes a, and which is hollow throughout, has
fast upon it the pulley D¹, through which the flier is driven by a belt 1)² from the
pulley D on the shaft C. The other piece b¹, which may be called the exten-
sion piece, and is a mere prolongation of b, has an eye 10 in its outer end, and is
provided at its inner end with a socket 7, which is bored centrally to receive the
terminal portion of the piece b, on to which the said socket is tightly driven, so
that and are practically one piece, their separate construction being merely
for convenience of applying the capstan H and its driving mechanism. The
capstan H, concentric with the flier, is fitted to turn freely on the extension piece b¹,
but is confined lengthwise thereon between a solid shoulder 8 on said piece and a
collar O, which is fitted tightly on said piece, and secured firmly thereon by a set
screw e. Between the inner end of the extension piece and a shoulder 9 on the
piece b, there is loosely fitted to the flier journal a pulley G₁, which receives
motion through a belt G2 from the pulley G on the shaft C; and on or fastened
to the said pulley is a bevel gear L, which is geared through a loose intermediate
bevel gear M carried by the flier journal B, with a bevel gear N fast on the
capstan. Said bevel gear M is fitted to turn freely on a pivot f, which projects
outwards from the flier journal. In the example represented, this pivot consists
of the shank of a set screw f, which is screwed through the side of the socket 7:
of the extension piece b¹, and made to bite on the part 6 of the journal, for securing b
and 6 together. The bevel gears being all of one size, the capstan is caused to
rotate at the same speed as the pulley D', but in the opposite direction. The
pulleys G G and D D¹ are so proportioned, that the pulley D¹ rotates faster than G¹,
which is thus caused, through the gears L, M, N, to drive the capstan slower than 3
the flier, and in the opposite direction.
The collar before mentioned carries two light guide sheaves
serves to guide to the capstan the twine 12, or material which is being spun or
9, either of which
twisted, and which passes into the flier journal B₁ through the eye 11 in the end
of the said journal. The socket 7 of the extension piece carries two similar 3
sheaves h, either of which serves to guide the twine, or spun or twisted material,
to the eye 11, which is formed in the socket 7 and corresponding portion of the
piece of the journal B¹, and through which the material passes again into the
hollow portion 61 of the journal, through which it passes onward to the flier B.
The flier journal is represented as having a counterbalance M' applied to it opposite 4
the bevel
gear M.
Firmly secured to the collar 0, which, as will be understood, is virtually a part
of the flier journal, there is a spiral guide P, which loosely, but closely, surrounds
the capstan, the sides of which are straight, that is, without the grooves common to
flier capstans in common use. This guide is represented as formed of coiled wire, 4
with the spaces between its coils wide enough for the passage of the twine or
material which is coiled several times around the capstan, and which, by the
rotation of the capstan independently of the flier, is wound upon the capstan, and
so drawn into the flier journal, and over the sheave g, while said guide, by its
rotation with the flier independently of the capstan, pushes said material onward 50
along the capstan, whence it passes over the sheave h, to enter the hollow portion
of the flier journal through the eye 11, thence passing on through the journal to
the body of the flier, to be thereby wound upon the bobbin.
The capstan arranged concentric with the bobbin according to this invention, is
subject to the minimum of centrifugal force in its rotation, and consequently the 55
least possible wear, which is of very great importance in fliers which run at a very
high speed.
