Improvements in Bobbin and Thread Holders for Spindles of Spinning
Machines.
I, OLIVER CROMWELL BURR, of North Adams, in the County of Berkshire, in
the State of Massachusetts, U.S.A., Spinning Mill Boss, 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 improvements in bobbin and thread holders for spindles
of spinning machines; the object thereof being to provide a simple, cheap and
effective means for holding the bobbin in engagement with the spindle and means
for holding and releasing the thread or yarn, the construction of the device
being such as to embody in a single article of manufacture a bobbin-holder
and a thread holding and a releasing device which comprises in the make-up of the
structure a bobbin-holder. having a plurality of spring arms carried by the
spindle and positioned thereon so as to contact with the periphery of the head of
the bobbin to hold and center the same on the spindle, the device also including
a thread-holder.
In the practical embodiment of my invention, I employ a thread-holder which
is of less diameter than the head of the bobbin and a bobbin-holder which does
not extend materially beyond the bobbin-head, the same comprising resilient arms
which engage with the periphery of the bobbin head without projecting above the.
same.
:
-
In the prior state of the art, it has been common to provide the spindle
of a spinning, machine with a bobbin holder consisting of oppositely disposed
spring arms which are carried by the spindle and adapted to be forced apart by a
downward pressure of the bobbin so that the bobbin head would be engaged by
the upwardly projecting ends of the spring arms which held the bobbin on the
spindle by frictional contact with the bobbin head; or with a recess formed in the
under side of the head, means also, being provided whereby the thread could be
held while doffing the, bobbin.
The present invention consists in the special construction and combination of
the parts as will be hereinafter set forth and specifically pointed out in the
claims.

page_text: In the accompanying drawings-
Figure 1 is a side view, partly in section, the section being taken through the
bobbin and through the bobbin holder and thread holder.
Figure 2 is a side elevation, the bobbin holder and thread holder being shown
in section.
'
Figure 3 is a perspective view showing the parts separated.
A refers to the spindle, to which, the bobbin holder and thread holder, is
attached, the spindle being of the ordinary type. a refers to a collar or sleeve
of malleable metal, as brass, copper or soft iron-the internal diameter of which
is approximately the same or slightly less than the diameter of the spindle where
it is desired that the parts shall be attached to each other. 6 refers to a disk
having at its periphery a downwardly extending V shaped flange b' and between
this flange and the central opening in the disk are apertures 63. Immediately
above the disk b is positioned the bobbin holder C which consists of a central
portion of approximately the same diameter as the disk b, the same having
outwardly or radially projecting arms c with upturned ends which are adapted
to grasp the head of the bobbin. This bobbin holder has on a line with the
apertures 3, apertures 2. The parts and C are held in rigid engagement with
each other and are fixedly attached to the collar or sleeve a and if desirable these
parts may be integral with each other. Drefers to the movable member of the
thread-holder which is movably mounted on the sleeve or collar a,. the same
having an aperture d of slightly larger diameter than the collar or sleeve,
upwardly projecting pins which are rigidly affixed to the upper portion
of the movable member I and a bevelled upper edge or periphery d² which is
adapted to engage with the bevelled or inner portion of the depending V-shaped
flange 6 of the disk. The movable member D with the exception of the pins
may be spun or struck up from a piece of sheet metal and the side flares outward,
this member being bell-shaped and of sufficient depth to extend below the collar
or sleeve a so as to form a cover or protector for the helical spring E' which is
placed over the collar so as to engage with the movable member D and a washer F
which is placed over the lower end of the collar or sleeve.
When the parts are assembled upon the collar or sleeve a the ends of said collar
or sleeve are expanded and upset so as to hold the parts C. b and the washer F in
rigid engagement with the sleeve a, the spring and bell-shaped member D being
movable upon the collar or sleeve. The pins d' carried by the member D project
through the apertures in the parts & and C and are engaged by the bobbin-head
when it is held by the bobbin holding arms of the part C.
By the construction shown, the parts are all connected and the movable member
of the thread-holder covers the spring so that there is no liability of the yarn
being caught between the coils thereof. The movable member D is adapted
to enter the fixed member so that the thread when placed between said members
will be securely held, and the parts are so shaped as to provide for the automatic
taking up of wear. It will be further noted that the parts are so constructed
that they are all held together by the collar or sleeve, and said collar or sleeve is
adapted to be placed over the spindle and driven to the desired position thereon,
which driving on and expansion of the sleeve will only tend to make more secure
the parts which are in fixed engagement with the same. This improvement is
susceptible of application to spindles already manufactured and when applied
it not only serves as a bobbin-holder and a thread-holder but also centers the
bobbin on the spindle.
The bobbin-holder has preferably three radially projecting arms with up-
turned ends to engage the side of the bobbin head, though a greater number may
be used if desired, and as said arms are attached to a common center it is obvious
that they will center the bobbin on the spindle which is not the case should
the holders which engage the bobbin head be susceptible of independent movement,
it will also be noted that the thread-holder is positioned below the bobbin and its
head.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st. In a bobbin and thread-holder for spindles, the combination of a bobbin-
holder connected to a spindle so as to externally engage the bobbin, a part of the
