1 ALFRED GEORGE BROOKES, of 55 and 56 Chancery Lane, in the County of
London, Chartered Patent Agent do hereby declare the nature of this invention
to be as follows:―
This invention relates to that class of sole sewing machine using a rotating
horn, and has for its object to provide improved means for heating the horn
whereby the wax is kept at the proper temperature for sewing.
Prior to this invention the horn has been kept warm by a lamp; by a gas
flame; and by steam made to circulate through suitable pipes; but in accordance
with this invention a hot liquid which may be hot water is depended upon to
supply the necessary heat, and it is arranged to heat the liquid or water by
conduction of heat from a liquid or water jacket surrounding a reservoir which
surrounds and rotates with the horn spindle.
In this invention there are no joints to leak and no packing to deteriorate..
The frame-work, bearing. block, horn, horn spindle, upright shaft extended
through the horn spindle and provided at one end with a gear and at its other
end with a gear, the tension device, the wax pot, and the stripper may be all as
usual.
In accordance with this invention as communicated to me there is applied to
the horn spindle a cylindrical reservoir, and for the best and most economical
results I have applied between the reservoir and the horn spindle a non-heat-
conducting gasket composed preferably of asbestos.
The reservoir has extended from its upper end a suitable pipe which enters the
chamber forming the bottom of the wax pot.
A pipe leads from the chamber up inside the horn and down again, joining the
pipe, which has its lower end extended into the reservoir, in practice, to a point
lower down than the end of the first named pipe.
Water heated in the reservoir will, by the rising of the hot water in the pipe,
cause a circulation of the hot water from the reservoir into the chamber, out
through pipes, and back again through pipe to the reservoir.
The chamber of the wax pot has at its front end a short pipe provided with a
stop cock, having a plug which may be turned to open the valve and draw water
from the chamber as may be desired.
The hot water reservoir is surrounded by a stationary jacket secured in suitable
manner to the stand.
This jacket by pipe is in communication with a source for supplying hot water
or steam, and with a pipe for the escape of steam from the jacket, the hot jacket
communicating its heat to the reservoir, and the water therein.
To prevent the entrance of dust between the exterior of the reservoir, and the
interior of the jacket, it is preferred to place a washer on the top of the reservoir
to cover the joint between it and the jacket.
When it is desired to heat the horn quickly, as in the morning to commence
work, means are provided whereby the steam may be admitted directly into the
water.
For this purpose there is used an auxiliary pipe having a stop cock or valve,

page_text: one end of said pipe, being connected with the reservoir, the other end of said
pipe being carried over to the other side of the horn spindle and connected to a
block attached to the spindle by a screw, said block having preferably a concaved
inlet or port.
The jacket has an auxiliary pipe provided with a stop cock or valve, the upper
end of the pipe being attached to a nozzle, the end of which is shaped to fit the
mouth of the block, an adjusting device shown as a screw, extended through an
ear attached to the jacket, being adapted to act upon and force the nozzle into
said mouth when the horn is rotated far enough to bring the mouth of the block
opposite the said nozzle.
The nozzle and block having been put together, and the stop valves opened,
steam may be forced into the reservoir to heat the water, and this done the said
valves will be closed and the screw withdrawn, leaving the machine ready to be
started, and thereafter the water, the reservoir having been previously properly
filled, will be kept hot by the steam, or it may be hot water, in the jacket by
conduction.

I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane in the County of
London,Chartered 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 :-
.
This invention relates to that class of sole sewing machine using a rotating horn,
and has for its object to provide improved means for heating the horn whereby the
wax is kept at the proper temperature for sewing.
Prior to this invention the horn has been kept warm by a lamp; by a gas flame;
and by steam made to circulate through suitable pipes; but in accordance with this
invention a hot liquid which may be hot water is depended upon to supply the
necessary heat, and it is arranged to heat the liquid or water by conduction of heat
from a liquid or water jacket surrounding a reservoir which surrounds and rotates
with the horn spindle.
In this invention there are no joints to leak and no packing to deteriorate.
Fig. 1 in front elevation, shews a sufficient portion of a sole sewing machine to
enable this invention to be understood;
Fig. 2, an enlarged longitudinal section of the upper part of the horn;
Fig. 3, a like section but of the lower part of the horn and the bearing for the
lower end of the vertical shaft to aid in rotating the usual whorl not shewn, in the
tip of the horn.
Fig. 4 is a section below the line x Fig. 2;
Fig. 5, a section below the line a¹ of the same figure, and
Fig. 6, a section below the line a³, Fig. 3.
The frame-work A, bearing block A*, horn A³; horn spindle A', upright shaft A³
extended through the horn spindle and provided at one end with a gear A* and at
its other end with a gear A', the tension device A, the wax pot A', and the
stripper A, are here shewn and may be generally in practice, all as usual.
In accordance with this invention, as communicated to me, there is applied to.

page_text: the horn spindle a cylindrical reservoir B, and for the best and most economical
results I have applied between the reservoir and the horn spindle a non-heat-
conducting gasket a* composed preferably of asbestos, and shown in Fig. 3.
The reservoir has extended from its upper end a suitable pipe a which enters the.
chamber a¹ forming, as shewn, the bottom of the wax pot.
A pipe a², see Figs. 1 and 5, leads from the chamber a¹ up inside the horn and
down again as at a, joining the pipe a', which has its lower end extended into the
reservoir, in practice, to a point lower down than the end of pipe a.
Water heated in the reservoir will, by the rising of the hot water in the pipe a,
cause a circulation of the hot water from the reservoir into the chamber a¹ out.
through pipes a³ a³, and back again through pipe a' to the reservoir.
The chamber a¹ of the wax pot has at its front end a short pipe a³ provided with.
a stop cock a, having a plug a' which may be turned to open the valve and draw
water from the chamber as may be desired.
The hot water reservoir B is surrounded by a stationary hollow jacket C secured.
in suitable manner to the stand A*. The pipe C' is fitted into the wall C³ of the
chamber C in order to afford means of communication for the supply of hot water-
or steam to the interior of the chamber formed by said wall or jacket from a.
source not here shewn. The pipe C is a pipe provided for the corresponding.
escape of water or steam from said chamber. This heated jacket C communicates
its heat to the reservoir B and to the contained water therein.
To prevent the entrance of dust between the exterior of the reservoir, and the
interior of the jacket, it is preferred to place a washer d on the top of the reservoir
to cover the joint between it and the jacket as in Fig. 3.
When it is desired to heat the horn quickly, as in the morning to commence-
work, means are provided whereby the steam may be admitted directly into the
water.
For this purpose there is used an auxiliary pipe e having a stop cock or valve e¹,
one end of said pipe, the right hand end Fig. I, being connected with the reservoir,.
the other end of said pipe being carried over to the other side of the horn spindle
and connected to a block e' attached to the spindle by a screw e said block having
preferably a concaved inlet or port, as best shewn in Fig. 6.
The jacket has an auxiliary pipe f provided with a stop cock or valve f¹, the
upper end of the pipe being attached to a nozzle the end of which is shaped
to fit the mouth of the block e, an adjusting device shewn as a screw f' extended
through an ear f* attached to the jacket, being adapted to act upon and force the
nozzle into said mouth when the horn is rotated far enough to bring the mouth of
the block opposite the said nozzle.
The nozzle and block having been put together, and the stop valves fl and el
opened, steam may be forced into the reservoir to heat the water, and this done
the said valves and f¹, will be closed and the screw withdrawn, leaving the-
machine ready to be started, and thereafter the water, the reservoir having been
previously properly filled, will be kept hot by the steam, or it may be hot water, in,
the jacket by conduction.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
In sole sewing machinery for use in the manufacture of boots and the like articles.
of wearing apparel:-
1. The use with a rotating horn having an attached hollow reservoir for the
reception of a liquid, and pipes leading liquid therefrom to the part of the horn to.
be heated and back therefrom into said reservoir, of an enclosing hollow jacket
adapted to heat the liquid in the said reservoir by conduction, as described.
2. The use with a rotating horn having an attached hollow reservoir for the
reception of a liquid, and pipes leading liquid therefrom to the part of the horn to.
be heated and back therefrom into said reservoir and the enclosing hollow jacket,.
י

page_text: of a non-conducting gasket between the horn spindle and reservoir, substantially as
described..
3. The use with a stationary hollow jacket, its auxiliary outlet pipe provided
with an open delivery nozzle, a horn spindle, its hot water reservoir, and an
auxiliary pipe e connected with said reservoir, and provided with a valve, of means 5
to put the delivery nozzle of said auxiliary outlet pipe and said auxiliary pipe e
into communication with each other, as and for the purposes set forth.
