An Improved Apparatus for Winding Bobbins or Spools for Sewing
Machines.
CHARLES RAINEY Watchmaker 88 Somerleyton Road Brixton London S.W. do
hereby declare the nature of this invention to be as follows:-
The object of the above machine is to wind bobbins or spools for the use of sewing
machines without requiring the attention of the machinist or stopping sewing. It
winds the bobbins or spools and when full, throws itself out of gear, cuts the thread,
and lays the spool or bobbin in a tray ready for use, without the assistance of the
machinist and while the machine is sewing.
It is constructed as follows:-
A. B. Fig. 1. is made the same as an ordinary bobbin winder (with the exception
of the end which is not stationary, but is on a pivot) and is made to slide backward
and forward (to put it either in or out of gear) on the plate D D D. E. is the cotton
guide and is made double Fig. 5. The top plate placing the cotton & the bottom
plate falling into a slot acts as a lock to retain the winder in position while it is in gear.
The bobbin while filling, gradually lifts the top plate which being attached to the
under plate also raises that out of the slot so that when the bobbin is full it is raised
entirely out of the slot and the winder is free and springs back as in Fig. 2. by a
spring which is fastened at its back Fig. 3. The end C Fig. 2 strikes on the point F.
thus throwing the bobbing out of the winder into the tray H at the same time the
knife K being attached to the winder meets the knife L cuts the cotton which was
previously running between them. The edges of the knives are shaped as in
Fig. 4 L being the stationary and K the moving knife. The guide E is fastened to
the plate. 00 Fig. 2. are holes for the ends of the bobbin to go in as in an ordinary
winder. These holes have a thread in them into which a peg is screwed to wind
spools. The cotton runs from the reel through a tension on to a swing guide and
thence on to the bobbin.
The especial novelty I claim is that the machinist can sew and wind bobbins or
spools at one and the same time thus saving time and labour.

An Improved Apparatus for Winding Bobbins or Spools for Sewing
Machines.
CHARLES RAINEY 67 Grove Hill Road Denmark Hill Camberwell, S.E. Watchmaker
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 the above machine is to wind Bobbins or Spools for the use of Sewing
Machines without requiring the attention of the machinest-It winds the Bobbin or
spool, and when full, throws itself out of gear, cuts the cotton, and lays the spool or
bobbin in a tray ready for use, while the machine is sewing-It is constructed as
follows A B Fig. 1 is an ordinary bobbin winder made to slide on the plate CCCC.
The end D is fastened on a pivot to allow for the bobbin to be put in and is held in
position by a spring N it also serves for the throwing out of the hobbin by striking
on the pin E when it is thrown out of gear. F is a plate which lies between the ends
of the bobbin and is pressed on the cotton by a spring. An elevation of it is shown
in Fig. 4. The Plate F is the front plate, and is the one that presses on the cotton.
The back plate to which the plate F is secured by screws acts as a lock and falls back
into a slot on the back part of the winder-As the bobbin fills, so it presses the
plate F from it, and thus the back plate is drawn from the slot and the winder is set
free The screw which is attached to the end D Fig. 1 is to alter it to the size of any
bobbin The plate F can also be taken out and another one put in for the same
purpose. The winder is made to slide along the plate C C C C as shown in Fig. 3 a
spring being attached to pins L and M on the winder and plate. The way it throws
the bobbin out will be seen by Fig. 2. On the winder being set free it slides along
the plate, the end D strikes on the peg E Fig. 2 thus dislodging the bobbin which
falls into the tray G. At the same time the knife K (which is also attached to the
winder) closes with the knife H and cuts the cotton. The knife H is stationary and
is fastened to the plate C C C C-H K Fig. 4 represents the shape of the knives.
The ends of the bobbin work into two holes into which two pegs can be screwed for
the use of spools.
Having now particularly described the nature of my said invention, and in what
manner the same is to be performed I declare that what I claim is :--
That spools or hobbins are wound, cut off, and layed ready for use, at the same
time as the machine is sewing and without the attention of the machinist.
Dated this Twentieth day of October 1888.
