Improvements in or relating to Holders for the Delivery Bobbins of
Yarn or Thread Spooling Machines.
A communication by JOSEPH DANIEL AIKEN, of Taftville, in the County of
New London and State of Connecticut, United States of America, Textile
Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil 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 is in "bobbin holders for spooling yarns and its object is to
provide a bobbin-holder of cheap construction and of durability, by means of which
yarns of different weights may be successfully spooled.
The bobbin holder proper may be formed of glass, metal, or any other suitable
material, in a single piece, and supported, when in use, by a socket secured to the
spooler frame in a manner hereinafter fully described.
To assist in explaining said invention the accompanying drawings are provided,
in which Figure 1 is a side elevation of a bobbin holder of this newly invented form
and of the support by means of which it is adjustably secured to the spooler frame.
Figure 2 is a central, sectional, view of the same and shows in place therein a bobbin
of ordinary form from which the yarn is delivered to the large upper spool on which
it is wound.
Figure 3 is a front end view of the holder and its support showing said holder
partially rotated, to illustrate the manner in which suitable tension is provided
(when desired) on the yarn being spooled. Figure 4 is a rear elevation of the
holder proper and Figure 5 is a detached view of a certain plate which forms an
important feature of the holder support.
In these drawings, the letter a indicates the holder proper, the same being
cylindrical in shape and open at each end. An open slot a is provided on the
upper side of the same throughout the greater portion of its length through which
the yarn passes when the device is in use.
The holder a is provided upon its circumferential surface at one end (the right
hand end as shown) with a conical head a². bindicates a portion of the device used
in securing the bolder in proper position upon the spooler frame. This portion 6
may be formed as a casting of metal or of any other suitable material, the upper
portion of the same being formed as a collar 6', the inner wall of which perfectly
coincides with the circumferential surface of the conical head a' of holder a. This
piece b is also provided with a downwardly extending portion 63 which is suitably
formed to partially encircle a rod c, which latter extends the entire length of the
spooler frame and serves to support the complete series of bobbin holders.
When the complete bobbin holder is assembled it will be seen by reference to
Figure 2 that the conical head a fits snugly within the collar b. To prevent said
head from leaving its seat in the collar, a plate d is provided, corresponding in
general outline to the outline of the piece b, the upper portion of the same being
formed as a disc d' and the lower portion as a tail piece d. (See Figure 5.)
The piece d is secured to the section 6 by means of a bolt e, and it will be seen
that, when the sections ò and d are forced toward each other, by screwing down the
nute of bolt e, the disc portion d' of section d will bear against the head a² of
holder a, thus closing the opening at the rear end of holder a and forcing the same

page_text: into its seat in the collar b¹, retaining the holder firmly therein; while at the same
time the tail portion will serve to clamp the rod c firmly between sections 6 and d.
That portion of rod c bearing against tail portion d' is flattened somewhat to prevent
the complete holder from rocking, or becoming displaced upon rod c, when said
bolder is clamped thereon. To prevent section d froin rocking on bolt e and thus
becoming out of alignment with section b, the former is provided with a stud or
projection f, which, when the parts are properly assembled, enters a corresponding
notch g in section b, thus preventing any liability on the part of section d to rock
upon its pivotal bolt e.
In assembling a complete holder of the described construction, the section a is
first introduced into the collar until the head a² enters the collar and is seated
therein. The section b is then so placed upon the supporting rod c that its portion 6ª
partially encircles said rod, as described. The section d is next secured firmly to
section by bolt e, thus forcing the holder a firmly into its seat in collar and at
the same time clamping the rod c firmly between the portion 63 of section b and
portion of section d. When the parts are thus assembled it will be seen that the
complete holder is firmly secured to and supported by rod c.. Said rod c is
preferably rocked slightly to tilt the complete holder as shown for a purpose to be
explained.
Assuming now that a holder of the described construction is provided and that it'
is desired to use the same, a properly wound bobbin is introduced into the open end.
of the holder with its thread delivering through opening a'. The bobbin (which
revolves freely in the holder) is prevented from working out of the front open end
of the holder by reason of the fact that the latter is slightly tilted, as illustrated and
as above mentioned, said bobbin being thus caused to travel by gravity downward
toward the right hand (as shown in the drawings) where the head of the bobbin
rests against disc d'. Should no great tension be required upon the yarn the same:
18 allowed to deliver freely and directly from the bobbin through the slot a¹ as seen
in Figure 1. Should it however be required to provide a tension for said yarn, as
the same leaves the bobbin, it will be seen that this may be easily accomplished by
simply rotating somewhat the holder a, thus compelling the yarn to draw from said
bobbin over the edge of slot a', thus producing frictional resistance which is.
increased proportionately with the degree of rotation of the holder, as will be easily
understood.
To lock the bobbin holder in position after adjustment as described, the same is
provided at its enlarged end (right hand as shown in Figures 1 and 2) with
notches 771, and to coact therewith, a stud n, similar to stud f, is located upon plate d
as shown in Figure 5. When plate d and piece bare clamped together, this stud n
enters one of the notches m, the latter having been previously properly adjusted
relative to said stud n.
The holder may be easily rotated by simply easing up the nut el until the stud n
is withdrawn from its notch m, when the holder is free to be rotated until the
desired tension is secured as already explained.
The piece band plate d are then again clamped together, the stud n entering
that notch which may have been adjusted coincident therewith, thereby again
firmly locking together the various elements of the complete device.
In order to reduce friction to a minimum as would be desired when spooling
fine yarns, two or more ribs a* are provided on which the bobbin is supported.
The holder being tilted, as above explained, it will be seen that any dirt
collecting therein will travel by gravity to the lowest part of the same (the right
hand end as shown in the drawings) the end of the bobbin holder being enlarged
as at a. To prevent any dirt which may collect in said enlarged portion from
clogging therein, a small hole d³ is cut in disc d', said hole being so located in disc d'
that the dirt may pass freely therethrough and thus leave the holder clean at all
times. This enlargement a also provides clear space in which the head of the
bobbin may revolve, without resistance, when the yarn is drawn off the bobbin and
the same is gradually lowered.

page_text: The complete device is of very simple construction and by reason of its easy
manner of adjustment to produce any desired amount of tension upon the yarn,
the operative has perfect control of the yarn as the same is delivered, thus
assuring better results (particularly with fine yarns) than it has been possible to
attain heretofore.
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. A bobbin holder consisting of a cylinder, each end of which is open, a disk
for supporting the cylinder, said disk also closing one end thereof, and means for
clamping said end of the cylinder against the disk, substantially as set forth.
2. In a bobbin holder, in combination, a slotted shell with conical end as set
forth, a supporting ring with correspondingly cone shaped inner wall and means as
specified for clamping said shell and ring together.
3. A bobbin holder consisting of an open-ended cylinder having an opening for
the escape of the yarn when in use, clamping sections for engaging with the
cylinder and with the frame, and means for causing the sections to simultaneously
engage with the frame and with the cylinder, substantially as set forth.
4. A bobbin holder consisting of an inclined open-ended cylinder longitudinally
slotted nearly its entire length, a clamp composed of two sections, one end of the
said clamp engaging with the cylinder and the other end adapted to engage with
the frame, and means intermediate the frame and the cylinder for drawing the
sections toward each other substantially as set forth.
5. A bobbin holder consisting of an open-ended cylinder having a longitudinal
slot nearly its entire length, a clamp composed of two sections, one of which has a
disk at one end and a notch at the opposite end, and the other section has a pin at
one end to engage with the notch, and a ring at the other end for engaging with
the cylinder, and means for securing the clamps together, whereby one end of the
clamp is adapted to engage with the frame and the other end to engage with the
cylinder, substantially as set forth.
6. A bobbin holder consisting of an open-ended cylinder having one end tapered
and having a hole in its side, a flat sided rod, a clamp composed of two sections,
one end of which bears against the flat portion of the rod and the other end is
provided with a disk for supporting the cylinder, and the other section has a curved
portion at one end to engage with the rod and a tapered ring at the other end to
engage with the cylinder, and a tightening nut between the rod and the cylinder,
substantially as set forth.
7. A bobbin holder consisting of an inclined open-ended cylinder having a
longitudinal slot nearly its entire length, a disk at one end of the cylinder having
a hole registering with the lowest point of the cylinder, and means for securing
the cylinder to the disk, substantially as set forth.
