This invention relates to certain improvements in sewing machines of the class
having rotating hooks or similar instruments for taking up the loop of the needle
thread and has for its object to dispense with the ordinary spool case and spool
or bobbin and in its place to provide a case or carrier of suitable construction so
as to allow of employing an ordinary reel of cotton and so save considerable time
which is usually taken up in the winding of spools or bobbins.
In carrying this invention into effect we bolt or otherwise attach to the under-
side of the bed plate of a sewing machine in the place of the usual spool holder
a frame piece or holder projecting downwards and formed' as is hereafter more
particularly described on one side to receive and hold in position a reel case or
carrier formed as a cup of size and depth sufficient to take an ordinary reol of
cotton. Inside and near to the bottom of this reel case or carrier there is fitted a
circular plate formed to present a convex upper surface and through the centre of
this plate a pin is passed to serve as an axis for the reel of cotton to turn around
in a vertical position this pin after passing through the central pláte is secured to
the bottom of the reel case or carrier.
..
The bottom of the cup or reel case is rounded off in such manner as to allow
the hook carrying the thread from the needle to revolve around it and to receive
the thread from the hook which passes around the said cup or reel case and up over
the top of same to complete the stitch 'and whereas we have since our' application
for Letters Patent on the 20th October 1884 N° 13,873 made further improvements
in detail of construction, which will enable our invention above referred to, to be
used with great advantage which further improvements are the subject of an
application for further Letters Patent bearing date the 28th day of February 1885
and numbered 2734 and which are described in our provisional spécification left
with our said application, we hereinafter refer to and propose to use in connection
with this invention such further improvements without however making any.
claim to them' as forming part of this invention or as being the subject of our
present patent of 20th October 1884 N° 13,873.
In the drawings hereunto annexed Fig 1 is a view from the left hand or needle
end of the machine showing the improved appliance, in position and Fig 1*
represents a modification of the bearing of the hook spindle
Fig.2 is a top view of the parts shown in Fig 1 with the bed plate removed but
indicated in broken and dotted lines.
Figs 3 and 4 are front and back views according to Fig 1 of the reel cup holder.
Fig 5 is an underview of said holder detached and Fig.5 shows a modification
wherein the holder is of a piece with the bed plate and one of the downward
projecting arms of the holder is hinged to allow of the reel cup being placed in
and to be removed from position.

Fig 7 shows an end on view of the hook in position as shown in Fig. 1 that is
just as the point takes the loop of the needle thread.

thread loop onto the reel cup.
Like letters refer to similar parts in the drawings.
We will now describe the fitting of a sewing machine according to this invention.
a is the bed plate; b is an opening in the bed plate below the head of the machine
and needle bar and presser foot; b¹ is a plate over which the work runs said plate
being arched up as shown in Fig 1 to accomodate the extremity of the hook as it
rotates, c is a bearing upon underside of bed plate a carrying a spindle & set on
line z, z at an angle obliquely to the central line y, y of the reel cup e and holder f.
The said spindle d is secured in the bearing.c by a shoulder and nut d' and carries
thereon a hollow spindle or sleeve d² which carries the rotating hook and the
said spindle d is provided with a bearing piece d³ to aid in holding the réel cup e
as will be hereinafter described.
The said hook g rotates in a circular plane whereof a transverse axis is
represented by line; The motion of rotation is given to the hollow spindle d²
by the bevil wheels has represented or may be by universal joint connection or
otherwise as convenient from the main driving shaft of the machine and the needle
will be mounted and operated substantially as ordinarily. The feed will be effected
by means of a serrated edge roller mounted in a forked shoe upon the lower end of
the presser bar said roller being operated by a pawl which engages with the
serrations of the roller and said pawl will be worked by a jointed lever from the
main motion shaft.
In this machine a take up or thread lifter is not necessary because the loop of
the needle thread is taken first by the point of the hook, is then spread out under
the reel cup and thrown off the hook onto the cup just before the point of the hook
reengages with the next loop of the needle thread this however may now be
considered to have taken place but meanwhile the last preceding loop is being
drawn up around and off the cup so engaging with the reel thread so forming the
lock stitch the stitch being closed by the slack off the cup being taken up again by
the spreading action of the hook as represented in Fig 9.
From the foregoing description the timing of the machine will be readily
understood by any practical operator.
The stop or shoulder g' on the shank of the hook g is provided for the needle
thread to bear against at the point of time when the loop of thread has been spread
out before casting off onto the cup and the curved portion g² serves in conjunction
with g' to the same purpose. The said hook may be made of skeleton form of steel
wire or be of a curved plate having like configuration of outline.
The cup holder f Figs 1, 3 and 4 consists of a conically shaped recessed cap f
into which the head of the reel cup e takes and it is fitted with arms f³, f³ for
supporting the said reel cup e against or together with the bearing piece d³ thus
loosely but securely holding the reel cup e and said reel cup holder f is either a
movable piece fitted upon an arm k capable of turning upon the centre k or the
conical cap f¹ may be cast on the bed plate and have one of the arms for f³
hinged so as to be turned back thus in either case providing for the reel cup being
readily placed in position or being removed.
The reel cup e is made. with a slit e' therein so as to allow of the metal of the
cup springing together and nipping the reel thread so as to give tension thereto.
The opening of the slit will be regulated as required by the screw e² and a small
cam or eccentric ed thereon which bears against the metal of the cup and a small
bar e is provided against which the reel thread will run, The cup is made conical
at the bottom externally and internally there is mounted on the arm e a hollow

page_text: spindle which serves as the axis of the reel of cotton, a removable tube e fits
upon the spindle e said tube e being made taper and with, knife edges e³ so as to,
hold fast to the wood of the reel and ensure its central position on spindle e or it
may be made simply as shown in Fig 6°. The thread from the reel is passed down:
through the slit e¹ over the bar e and up through the hollow spindle e tension
holes may be provided as convenient.

The improved combined parts are shown in Figs 1 and 2 in relation only to the
needle of the machine without the rest parts as various machines of ordinary.
construction may be altered to receive and work with these improvements.
The simplicity of a machine constructed upon the plan above described
recommends it both to the constructor and the operator. for instance a reel of
500 yards can be placed immediately in the cup of the machine and the cup be
placed in its holder without any necessity for particular adjustment.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
Firstly. The use in sewing machines such as are herein referred to of apparatus,
for holding and supplying and guiding thread constructed substantially as herein.
described.
Secondly. The combination of parts forming our improved case or cup for holding
and supplying thread constructed substantially as herein described.
Thirdly. The combination of parts forming our improved means for holding and.
supplying thread constructed and used substantially as herein described and
illustrated in the annexed drawings.
