"Improvements in or relating to Machines for Levelling the Soles
of Boots and Shoes."
I, FREDERICK WILLIAM FARR, of 16 Mentmore Terrace, London Fields, London, in
the County of Middlesex, Boot and Shoe Manufacturer, do hereby declare, the nature
of this invention to be as follows:-
This invention relates to improvements in machines which are employed for
levelling the soles of boots and shoes.
In this class of machine it is customary to impart a rolling or oscillating motion to
the stand or support on which the boot or shoe is mounted simultaneously with the
reciprocating or radial reciprocating motion of the levelling roller.
Now the object of this invention is to heat the levelling roller whereby the
levelling operation may be more quickly performed than with a cold roller as hitherto,
the creases and lumps may be more readily removed from the sole and at the same
time the sole may be simultaneously, wholly, or partially burnished.
According to this invention the levelling roller may be heated by either gas or hot
water, or steam, or hot air conveyed thereto by any suitable and convenient means,
such as for example, say, by the flame or flames from one or more atmospheric or
other gas
burners or jets, arranged to act upon the top of the roller. Or a series of
burners or gas jets, suitably arranged as regards the admission of gas and air, and for
the emission of the products of combustion, may be provided and made to pass
into the interior of the roller, say, for instance through its bearings. Or steam,
hot water, or hot air may be made to pass say either directly into the interior of the
roller, or by say, a series of circulating pipes or tubes, or jackets, or cells, or chambers,
or compartments, or combinations of two or more of them arranged in any con-
venient position in, on, around, or at one or both ends thereof or in any other
position thereon, or therein. The other parts of the machine may be of the usual
and ordinary construction.

'Improvements in or relating to Machines for Levelling the Soles
of Boots and Shoes."
I, FREDERICK WILLIAM FARR, of 16 Mentmore Terrace, London Fields, London,
in the County of Middlesex, Boot and Shoe Manufacturer, 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 improvements in machines which are employed for
levelling the soles of boot and shoes.

page_text: In this class of machine it is customary to impart a rolling or oscillating motion
to the stand or support on which the boot or shoe is mounted simultaneously with
the reciprocating or radial reciprocating motion of the levelling roller.
Now the object of this invention is to heat the levelling roller whereby the levelling
operation may be more quickly performed than with a cold roller as hitherto, the
creases and lumps may be more readily removed from the sole and at the same
time the sole may be simultaneously, wholly, or partially burnished.
In the drawings hereunto annexed,
Fig. 1. is a front elevation, and Fig. 2. a side elevation of a sole levelling
machine constructed according to this invention.
A is the framework of the machine B the last or jack upon which the boot or shoe
is mounted in the supporting cradle C capable of being oscillated to and fro, and
being rocked from side to side so that the whole of the sole of the boot or shoe may
be acted upon by the levelling roller D which is carried in suitable bearings in the
arms E. The arms E are capable of being acted upon by treadle F for increasing
the pressure upon the roller D at pleasure.
All the above parts as well as parts not shown may be of the usual and ordinary
construction and operated by hand or power in the usual manner.
Instead of employing the levelling roller D as is usually done it is according to
this invention heated by either gas or hot water or steam, or hot air conveyed thereto
by any suitable and convenient means, such as for example, say, by the flame or
flames from one or more atmospheric or other gas burners or jets, arranged to act
upon the top or end of the roller.
Or a series of burners or gas jets arranged in or on a pipe G suitably arranged as
regards the admission of gas and air, and for the emission of the products of
combustion, may be provided and made to pass into the interior of the roller D, say
for instance through its bearings. Or Steam, Hot water, or Hot air may be made to
pass say either directly into the interior of the roller, or by say, a series of
circulating pipes or tubes, or jackets or cells, or chambers, or compartments, or
combination of two or more of them arranged in any convenient position, in, on, 3
around, or at one or both ends thereof or in any other position thereon, or therein.
In the drawing hereunto annexed the pipe G (a portion of which may be formed
of iron, which may be connected to a service pipe by rubber tubing) is shown secured
to one of the arms E and arranged so that the gas jet is thrown on to say the end
of the roller D. Or the gas jet (or steam, or hot air or water) may pass at one end 3
into the interior of the roller through suitable glands arranged in say the centre of
the bearing, and, say, the gas (steam or hot air) or products of combustion, after
passing the entire length of the roller escapes through a pipe GI passing through a
gland arranged in the bearing at the opposite end of the roller D.
Other parts of the machine not explained or shown may be of the usual and 40
ordinary construction.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The arrangements and combination of the parts forming the means for heating 45
the levelling rollers of machines employed for levelling the sole of boots and shoes
as and for the purposes herein set forth.
