Improvements in Boxes for Thread Holders.
I, ALFRED VINCENT NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide a suitable box for receiving the thread
holders for which Letters Patent were granted to my communicant dated
12th January 1887, No. 518, and presenting the same to the sewing machine while
effectually protected from dirt and delivering the thread at a proper & uniform
tension.
The box is made circular, & of a capacity to receive freely the laden thread
holder. It is made of two thin shells (of pasteboard, by preference), shaped at
their centres to form two pressing surfaces, which are to grip the centre of the
thread holder, a star-shaped disc.
Projecting inwards from the flat face of one half of the box, is a tube which is
to receive the thread holder, and support it clear of the inner periphery of the
box. The box is supported on the sewing machine by a stud pin projecting from
the arm or frame, and entering the tubular centre of the box. The thread will be
led out of the box at the periphery, passing first through a notch cut in the lip
of one half of the box, and out at a hole formed in the periphery of the other
half. By adjusting these parts relating to each other, any desired amount of
tension may be put upon the thread.
In moulding the box in paper, the centres of the shells may be indented, to
form the internally-projecting gripping surfaces between which the holder revolves
under the drag of the thread. It will be obvious that thin sheet metal, or other
materials than paper, may be used in the manufacture of the boxes, but for
cheapness and lightness, paper or pasteboard will be in general preferred. To
secure stiffness with lightness, the boxes may be corrugated, if thought desirable.

Improvements in Boxes for Thread Holders.
I ALFRED VINCENT NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane in the County of London, Patent Agent, 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:―
The object of this invention is to provide a suitable box for receiving the filled
thread holders for which Letters Patent were granted to my communicant dated
12th January 1887, No. 518, and presenting the same to the sewing machine, while
effectually protected from dirt, and delivering the thread at a proper and uniform
tension.
The box is made circular, and of a capacity to receive freely the laden thread
bolder. It consists, preferably, of two thin shells of pasteboard, shaped at their

page_text: centres to form two flat surfaces, between which is placed the central portion of
the thread holder, a star shaped disc.
Projecting inwards from the centre of the flat face of one half of the box, is a
tube which constitutes a hollow axle, and is to receive the thread holder, and
support it clear of the inner periphery of the box.
The box, when in use as a tension thread holder, is carried by a stud pin
projecting from the arm or frame of the sewing machine, and entering, for that
purpose, the tubular centre of the box. The thread will be led out of the box at
the periphery, passing first through a slot cut in the lip of one half of the box,
and out through a second slot formed in the periphery of the other half. By
adjusting these parts relatively to each other, any desired amount of tension may
be put upon the thread.
In the accompanying drawing,
Fig. 1 shews, in top view, the improved box fitted to receive a holder filled with
cotton thread.
Fig. 2 is a transverse section of the same, taken at the line 1. 2 of Fig. 1; and
Fig. 3 is an edge view of the box, shewing the opening through which the thread
is drawn.
Fig. 4 is a side view of the box with the cover removed and the filled thread
holder in position.
Fig. 5 is an internal side view of the box.
Fig. 6 is a similar view of the lid.
Figs. 7 and 8 are top and edge views of a shallower box, suitable for receiving a
silk holder; and
Fig. 9 shows the interior of the box with the filled silk holder in position.
A, B, are the two shells composing the box. ab are the central flat surfaces
between which the holder C is held. c is the hollow axle on which the holder
is loosely mounted.
To
This axle is composed preferably of two flanged metallic tubes, which fit the
one in the other.
The flanges of these tubes serve to grip the centre of the
shell A, and are supported thereby vertically in the centre of the box.
complete the manufacture, the inner end of the outer tube is turned over the end
of the inner tube by a burnishing pressure. When the filled holder is placed in
the box, the end of the thread is drawn through the slot in the periphery of the
shell A, and the corresponding slot in the periphery B is brought into coincidence
therewith, by the application of that shell or cover to the box A, as shown at
Fig. 3.
In Fig. 4 the holder is shown as filled by lapping the thread alternately to the
right and left over two consecutive arms or spurs of the holder, and in Fig. 9, a
kind of floral pattern is produced by lapping the silk over consecutive arms or
spurs at alternately opposite sides of the holder.
In
For the purpose of putting friction on the thread, it is only necessary to give a
slight axial motion to the cover B, and the thread will then be gripped in the slots,
the amount of friction being determined by the axial adjustment of the cover.
moulding the box, it is preferred to indent the centres of the shells, as shewn in
the drawing, to form the internally projecting flat surfaces a b, between which the
holder is free to revolve under the drag put upon the thread. It will be obvious
that thin sheet metal, or other materials than paper, may be used in the manufacture
of the boxes, but for cheapness and lightness, paper or pasteboard will be in
general preferred.
To secure stiffness with lightness, the boxes may be corrugated radially, if
thought desirable.
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
from abroad, I declare that what I claim is :-
The manufacture of boxes for thread holders as described, wherein the thread

page_text: holder is free to rotate under the draught of the thread, and by which the drag
on the thread may be regulated, as set forth.
