The remaining Figure or Figures illustrate the spooling machine bobbin supporter,
having its trough provided with a lining and a yielding insulating material inter-
posed between it and the trough, all being substantially as herein-after set forth.
The main purpose of my Invention is to hold or support a wound bobbin, while
its yarn or thread may be in the act of being unwound therefrom, and transferred
to and wound upon a spool.
Prior to my Invention the delivery bobbins of a spooling machine were generally
supported upon spindles, the employment of which, with their necessary adjuncts,
my Invention renders unnecessary, as in the place of such spindles I use either a
celled bar or a series of troughed bobbin supporters, as herein-after described. The
celled bar has a series of cells or cavities, one for each delivery bobbin, each of such
cells being open at its front or upper end, and provided with a slot opening through
its top and to such end.
In Figures 1 and 2 of the Drawings the frame of an ordinary spooling machine
is represented at A. One of the receiving spools is shown at B, and its supporting
spindle at C. D is the thread or yarn guide bar, furnished with a guide a, which
is arranged in front of the spool B. The bobbin from which the yarn is to be drawn
and spooled is shown at D', as placed in one of the cells or cavities b, b, &c., of a
long bar E, which is arranged with respect to the receiving bobbin and the yarn
guide, and within the frame A, in manner as represented. There is within the bar
E a series of cells b, b, each of them being open at its front end and closed at its rear.
It is also closed at top, except in having a slot c formed therein, and opening at the
front or mouth of the cell. Each cell has flaring sides and a curved bottom. When
a bobbin D' is laid within a cell its rear end will bear against the rear end of the
cell. The yarn from the bobbin is to be led up through the slot c, thence through
the eye of the guide a, and thence to the receiving spool, upon which the yarn is to
be wound in the usual way. I generally pivot or connect the cell bar to the
frame A, so that the former may be turned within the latter, and fixed in a manner
to bring the bar into the best position for supporting the bobbins relatively to the
guide bar. The cell bar has many advantages over the spindles for supporting the
bobbins, as it saves the expense of the oil required to lubricate their bearings. The
friction of the bobbin on the bottom of the cell obviates the necessity of any arti-
ficial arrangement for producing friction so as to impede the unwinding of the
thread. With the cell the tension on the thread or yarn is nearly uniform, and
consequently there is less liability of the breaking of the yarn when the cell is
employed in lieu of the spindle. Furthermore, the cost of the cell bar is very much
less than that of a set of spindles, and the yarn is not liable to be over-strained by
its use.
By having each cell open at its front end the bobbin can be easily introduced
into the cell or removed from it, as occasion may require; so also by having
the thread slot of each cell open at its front, we are enabled to pass the yarn into
the slot to better advantage than would be the case were the slot closed in front.
Instead of using a cell bar so pivoted or applied to the spooling machine frame as
to be capable of being turned laterally within it, and fixed in place in a manner to
bring the bar into the best position for supporting the bobbins relatively to the
guide bar, whereby any change in the position of the bar involves a simultaneous
movement of all the cells thereof. I prefer to use in a spooling machine a series of
separated cells or troughs, and to have each of them pivoted to one of a series of
supporting arms, all being as herein-after set forth. This enables me to effect the
adjustment of each cell or trough, independently of any other of the series, as cir-
cumstances may require, and thus to obtain a better adjustment of them than when
they are connected in one bar.
Figures 3 to 8 inclusive, represent a single cell bobbin supporter as above men-
tioned. It consists mainly of a trough A, and an adjustable friction arm B, the

page_text: latter being formed with an elbow or bend as shown at a. The arm is pivoted to
the trough A, or connected to it by a clamp screw b at its rear part so as to be
capable of being turned on such pivot and clamp screw b laterally toward either of
the two upper edges c, c, of the trough, and of being afterward clamped or held in
place by the screw. Through the bottom of the trough, and to open out of its front
end, is a slot d. The trough near its rear end is hinged to a supporting arm C, the
pivot of the hinge being a screw bolt e; provided with a screw nut f, all being formed
and arranged as shown. In order to fasten the arm to the frame of the spooling
machine, the said arm is flattened at its lower part and provided with a fastening
screw D and nut E as represented. The trough A I usually make of iron or cast
metal, and cover its inner surface and edges, or its entire surface, with the exception
of its rear end, with a mineral or silicious glazing or enamel h, such as is usually
applied to the inner surfaces of iron pots or kettles. The object of the enamel is to
prevent oxidation of and enable to be readily cleaned that surface or those parts of
the surface of the trough, which while the trough may be in use may be exposed to
contact with the yarn of the bobbin. Such yarn usually being more or less oily
is liable to lubricate or impart oil to the surface of the trough, and thereby cause
it to readily gather filaments and dust. Besides, the yarn while being drawn
against an edge of the trough is liable to cut or wear into it, and render it uneven,
to the injury of the yarn, but by covering the edge or exposed surface of the trough
with enamel such wear will be prevented, and the yarn will run smoothly over such
edge or surface. The adjustable friction arm B may also be enamelled. The object
of having the friction arm B adjustable is to enable the angle of draft of the yarn
from the bobbin to be varied in order to obtain the requisite friction for winding
the yarn on the spool, the bobbin being laid within the trough, and the yarn from
the bobbin being led out of the trough and against either of the longer edges of the
arm.
The object of the slot d in the bottom of the trough is to enable the yarn to
be run from the bobbin down through such slot, and thence to the spool,
thereby obtaining a greater angle of draft and amount of friction than can be
attained with the friction arm alone. The object of pivoting the supporting arm C
to the trough, and providing the two with the clamp-screw and nut (the screw con-
stituting the pivot), is to enable the trough to be adjusted to the proper inclination
with the horizon. In lieu of applying the friction arm to the trough so as to be
adjustable independently of such trough, as described, the two may be connected
and applied to the supporting arm so as to be capable of being turned laterally in
order to vary the angle of draft of the yarn, all of which involves the principle of
the adjustable arm; in combination with the trough, tlie duty of the latter being to
support the bobbin, and that of the former, to vary the angle of draft. Another mode
of accomplishing the result would be to make the trough as a tube, slotted length-
wise through its top and open at its front end, and so applied to the supporting arm
as to be capable of being revolved more or less transversely to vary the angle of
draft of the bobbin thread or yarn going through the slot, such also involving the
principle of the adjustable arm under another form.
Figures 9 to 15 inclusive, represent a single cell bobbin supporter, somewhat
differently constructed, it being provided with a rest A for sustaining the bobbin.
It also has, over the said rest, two gravitating or self-adjusting lips B, B, which are
suspended from the opposite edges of a carrier C, having an arm a projecting down
froin and at a right angle to it. There is an car b at the lower part of the arm, and
there is to the rest A an ear c. Between these two ears the flat head d of the sus-
taining arm D is arranged. A clamp screw E provided with a nut F goes through
the said head and two ears, and serves to connect together the arm D, the rest A,
and the carrier C, and to admit of the proper adjustment of such parts, relatively
to each other, and to the guide bar of the spooling machine. The carrier Chas
tenons e, e, projecting from its opposite edges, and going loosely through corre-
sponding slots in the upper parts of the gravitating,lips. These tenons serve to

page_text: support the said lips, which can swing freely toward or away from each other on
the said tenons. They are kept in place by an arched cap G, which straddles the
tenons and lips in the manner shown, and is fastened down to the carrier by a
screw h, which goes through the cap and is screwed into the carrier.
At and near
their outer ends the lips are bent or flared as represented, in order to facilitate the
introduction of the bobbin between them, and each lip at its inner end is provided
with a shoulder or projection i, extending from it in manner as shown. Such pro-
jection is to prevent the yarn from the bobbin from accidentally passing up and
getting caught between the adjacent end of the lip and that part of the carrier
which is next thereto. When a bobbin is in the rest A, and between the lips B, B,
in manner as shown at F¹, the said lips embrace and bear against the opposite
sides of the yarn load k, and adjust themselves to it, as it may diminish in size by
the yarn being unwound from it. They readily open apart, while a bobbin with
its load is in the act of being placed between them. Their purpose is to hold the
bobbin steady, or from vibrating laterally or jumping about, as it will when laying
Joosely in a trough or cell unprovided with any means or devices for holding it
steady. Lateral vibration or jumping of the bobbin incident to a cell without
devices for steadying the bobbin often seriously affects the tension or draft of the
yarn, which it is very desirable to have regular or uniform. The gravitating lips
produce the requisite pressure or friction on the bobbin for steadiness of draft, and
fall toward each other as the yarn load may diminish in diameter. If desirable
springs may be applied to the lips and their carrier in order to force the lips
toward each other, but generally speaking the weight of the lips will suffice
therefor.
Instead of using gravitating lips, as described, I sometimes line the trough
with thin plate metal, and interpose between the said trough and the said lining
a yielding or elastic layer or packing, such as cloth, wash leather, or sheet
india-rubber, for instance, the object being to hold the bobbin steady, and reduce or
or prevent noise, as is apt to result when the bobbin is revolving, and rests in direct
contact with the trough. This is represented in Figures 16, 17, and 18, which show
a bobbin supporter, of which A denotes the trough; a, the lining; and b, the cloth
or packing, Figure 16 being a side view, partly in section; Figure 17, a transverse
section; and Figure 18, an end view of such a bobbin supporter.
