Improvements in Apparatus for Waxing Thread for use in the
Manufacture of Boots and Shoes and for other purposes.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 wax-pots or apparatus for waxing thread for use in the
manufacture of boots and shoes and for other purposes.
This invention has for its object to provide an improved wax-pot or apparatus
whereby the thread may be thoroughly saturated with wax, and the surplus wax be
then scraped off, and the said thread afterwards sinoothed, and the remaining wax
worked uniformly into the surface thereof.
In carrying the said invention into practice the wax-pot or cup is combined with
a scraper or device for removing more or less of the wax from the thread which
has had a long traverse through the said wax-pot or cup before reaching the scraper.
This scraper or device consists essentially in a stud having an annular groove,
preferably of varying depth, and a spring plate, the rotation of the stud bringing a
new portion of the groove uppermost.
Figure 1 is a plan, and
Figure 2 is a section on the line aa, Figure 1, showing the improved wax-pot or
apparatus for waxing thread.
Figure 3 is a side elevation and,
Figure 4 is a section on the line a Figure 3, both drawn to an enlarged scale,
showing a detail of construction.
Like letters of reference indicate corresponding parts throughout the drawing.
A is the wax-pot or cup, B is the thread to be waxed.
The wax-pot or cup A is provided with a top plate 6 having a cover U¹ hinged or
pivoted at b* thereto."
The top plate b is provided moreover with a downward extension 62, having an
horizontal arm or extension 63, at the underside of which is a stud 2 (shown in dotted
lines in Figure 2) on which is mounted a sheave or roller b*.
c is a hole provided in the top plate band in a vertical flange 6 depending
therefrom. d is a stud rotatably supported in a suitable bearing in the top plate bas
hereinafter described. e is a stuffing box having a screw-threaded plug or gland e¹
and a plug preferably formed of india-rubber or equivalent material such as usually
employed to wipe the wax into the body of the thread and smooth the wax uniformly
thereon. The said plug e is provided with a central hole corresponding with that
in the stuffing box e and gland or plug e and is compressed more or less as desired
by the said plug or gland e¹. This forins the smoothing device. The thread B to be
waxed passes or is led down through the said hole c from a suitable ball or bobbin, as now
commonly done in wax thread sewing machines. The said thread is then carried under
the lower side of the extension 63, round the sheave, pulley or roller and back under the
said extension, up over the stud d, and out through the said smoothing device, and
(when employed in combination with boot or shoe machinery) thence to the usual
tension device and thread guide, not shown in the drawing.
The thread by its long traverse through the wax in the wax-pot or cup A becomes
horoughly saturated with wax, and the surplus wax, and any adhering particles on
he outside of the thread has, for the best results, to be cleared or scraped off before
he thread enters the smoothing device.

page_text: For this purpose the said thread is passed over the stud and between it and a
plate or spring connected, as shown, to the top plate by means of a screw 3.
This stud and plate constitute the thread clearer or scraper.
The stud d has moreover a circumferential groove 4 through which the thread is
led, and by rotating this stud from time to time a new part of the groove may be
brought uppermost.
To provide for adapting the scraper or thread clearer to threads of different,
diameter I prefer to make this circumferential groove of varying depth, (as shown
more clearly in Figure 4) so that by rotating the stud a part of the groove of the
desired depth may be placed under the spring or plate d.
To enable the rotation of the stud to be conveniently effected it is provided with a
circumferential groove into which projects the extremity of a set screw 8 so as to
secure it in place, and at the same time permit the free rotary movement thereof.
The stud has moreover a series of holes 10 into either of which a point or lever may
be inserted for convenience of turning or rotating the said stud. These holes may
if desired be numbered in succession from the shallow to the deep parts of the
groove 4 thus enabling the operator to readily know the part of the groove which
is under the plate or spring.
The wax or material in the said wax-pot or cup A may be kept in a fluid or melted
condition by the application of heat thereto.
Having now particularly described and ascertained the nature of this 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 :-
First. In a wax-pot or cup the combination of a depending flange 6º, downward
extension 3, horizontally extending arm b³, sheave, pulley, or roller & mounted on the
said arm near that side of the said wax-pot or cup farthest from the opening c
through which the thread is led or passed into the said wax-pot or cup, with a scraper
or thread clearer consisting of an annular grooved stud d and a plate or spring d', and
a smoothing device to act upon the thread beyond the said scraper or thread clearer,
all substantially as and for the purposes heroinbefore specified.
Second. The combination with a suitable wax-pot or cup of a scraper or thread
clearer consisting in a rotatably mounted stud d having a circumferential groove of
varying depth, and a plate or spring &, operating as and for the purpose set forth.
Third. The combination of a wax-pot or cup, having a flange, and downward
extension, horizontally extended arm 63, and horizontally revolving sheave, pulley, or
roller 6, with the rotatably mounted grooved stud d and plute or spring d¹, and
smoothing device, substantially as described.
Fourth. The improved wax-pot or cup substantially as described with reference to
the accompanying drawing and operating as and for the purposes hereinbefore
specified.
