IMPROVEMENTS IN WINDING APPARATUS FOR SEWING MACHINES
Year: 1884

page_text: J ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Engineer do hereby declare the nature of the said invention for "IMPROVEMENTS
IN WINDING APPARATUS FOR SEWING MACHINES" to be as follows:-
The present invention has reference to an improved system of threadwinding
apparatus for sewing machines. which possesses several advantages over machines
hitherto in use for that purpose.
The thread winding apparatus consists essentially of the threadwinder carried by
a support which is attached either to the end of the driving shaft or to the fly wheel
in such a manner that the thread winder is adjusted to the central axis of the fly
wheel or of the driving shaft,
The details of the apparatus are capable of being somewhat varied according to
the description of sewing machine to which the apparatus is to be applied.
With the older makes of machines the support usually consists of a cylindrical
rod, threaded at one end and screwed into the centre of the fly wheel or end of the
shaft. Into this cylindrical rod the thread winder is screwed or otherwise suitably
attached. With machines having detachable fly wheels, the support is preferably
curved or stirrup shaped, secured by screws to the fly wheel at each end and
having the thread winder attached to its centre. The thread to be wound on to
the apparatus passes from the bobbin through an eyelet suitably adjusted and
through a guide held either by a separate support fixed to the table of the sewing
machine or attached by a bent support to the cover of the driving belt. This
thread guide is so arranged as to deliver the thread at an angle on to the winder.

I ALFRED JULIUS BOULT, 323 High Holborn, Middlesex, Engineer do hereby
declare the nature of the said invention for "IMPROVEMENTS IN WINDING
APPARATUS FOR SEWING MACHINES" (A communication from abroad by Carl
Hosch, Haida, Bohemia) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The present invention has reference to a thread winding apparatus of extremely
simple construction, and which can be produced very cheaply, in comparison with
other thread winding apparatuses, such as Carter's.
E
The thread winding apparatus consists essentially of the thread-winder, carried
by a support which is attached either to the end of the driving shaft or to the fly 1
wheel in such a manner, that the thread winder is adjusted to the central axis of
the fly wheel or of the driving shaft.
In the accompanying drawings, Figures 1 and 2 show the apparatus in its
simplest form, that in which it is usually fitted to sewing machines of the older
makers. The support a consists of a cylindrical peg which screws by means of its 1
threaded prolongation b into the end of the driving shaft d.. The pog a has a hole
bored in its outer end, into which is screwed the end of the thread winder. The
winding up of the thread is accomplished by the revolution of the shaft d.
The support a is necessary, because the fly wheel is made concave.
In the newer types of machines in which for the purpose of winding up the
thread, the fly wheel can be disconnected from the driving shaft d, the peg a
must be secured to the fly wheel f.
Such an arrangement is shown in Figures 3 and 4 the support is made stirrup-
shaped and secured by means of screws a¹ to the fly wheel.
It is not indispensable that the thread winder should be screwed into the
support, it can also be wedged into the support a, or attached in any other suitable
manner, whereby of course the end of the winder need not be threaded, but requires
to be squared or otherwise adapted.
Figures 5, 6 and 7 show the winding apparatus with the addition of a thread
guide g. The thread winder e is screwed into the support a, whilst the thread
guide g is so arranged that it delivers the thread from above diagonally on to the
thread winder as shown in Figure 6. This thread guide may be carried either by
a special support affixed to the table of the sewing machine as shown at h, Figure 5,
or by a curved support k, Figure 7, attached to the cover i of the driving belt.
The thread travels from the bobbin m through an eyelet n and through the
guide g on to the winder e as the Figures show.
"
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is
1st. The combination of parts, consisting of the thread winder e adjusted to the
central axis of the fly wheel for of the driving shaft d; by means of the hoop
shaped or cylindrical support a Figures 1 and 4, for the purpose of winding up the
thread used on the sewing machine.

central axis of the fly wheel for of the driving shaft & by means of the support a
