Complete Specification Left, 27th Sept., 1889-Accepted, 2nd Nov., 1889
PROVISIONAL SPECIFICATION.
Improvements in or relating to the Process of Finishing the Heels
of Boots and Shoes.
I, WILLIAM FAIRBURN HART, of the General Assurance Buildings, No. 1, East
Parade, Leeds, in the County of York, Patent Agent, do hereby declare the nature of
this invention, which has been communicated to me from abroad by Charles Smith
Larrabee, of 8, Untermain Anlage, Frankfurt-on-Main, in the Empire of Germany,
to be as follows:-
This invention has reference to improvements in or relating to finishing the heels
of boots and shoes in a quicker and superior manner.
According to this invention, after the heels have been pared by machinery in the
manner described in the provisional Specification accompanying my application for
Letters Patent No. 3, dated the first day of January 1889 they are taken to what is
termed a smooth finishing machine-that is, a machine in which a number of discs,
profiled to the shape of the heel, are mounted upon a shaft revolving in suitable
bearings at a high speed, said discs being provided on their peripheries with a number
of rasp teeth, soap stone, emery, or other abraiding material according to the degree
or stage of the finishing operation or process. After the heel has been brought to the
required shape by the herein described discs the heel is inked with any suitable heel
ink, and again submitted to the action of the smooth or finely faced discs of the
smooth finisher revolving at a very high speed whereby a considerable degree of heat
is evolved which causes the gum in the ink to fill the intersectics of the leather thereby
forming a skin on the top of the leather which prevents the ink from striking into the
heel, and also enables a good polish to be easily and readily obtained.
Dated this Thirtyfirst day of December 1888.

1, WILLIAM FAIRBURN HART, of the General Assurance Buildings, No. 1, East
Parade, Leeds, in the County of York, Patent Agent, (A communication to me from
abroad by Charles Smith Larrabee, of 8, Untermain Anlage, Frankfort-on-Main,
in the Empire of Germany, Engineer) 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 has reference to improvements in or relating to the finishing of the
heels of boots and shoes in a quicker and superior manner.
According to this invention after the heels have been pared by machinery in the
manner described in the Specification accompanying my application for Letters Patent
dated the first day of January 1889 No. 3, they are taken to what is termed a smooth
finishing machine, that is, a machine in which a number of discs profiled to the shape
of the heel, are mounted upon a shaft revolving in suitable bearings at a high speed,
said dises being provided on their peripheries with a number of rasp teeth, soap stone,
emery, or other abraiding material according to the degree or stage of the finishing
operation or process.

constructed according to my invention, Fig. 3 a view showing a portion of the finishing
dise profiled to the chang at the heal

page_text: In the bearings A, B, and C is mounted a horizontal shaft a in which is cut a screw
thread. On the shaft a are mounted any desired number of discs b, c, d, e which may
be kept at suitable distances apart by lock nuts or other convenient means.. The
discs may be about six or seven inches in diameter and vary from about one to
three inches in thickness according to the depth and underset of the heel to be operated
upon. The periphery of each disc is also profiled or shaped to suit the contour of the
heel to be finished. The peripheries of discs may be provided with rasp shaped
teeth or projections-that is a number of fine burrs are raised on the periphery at
suitable and irregular distances apart by a diamond or triangular pointed chisel or
other tool-arranged so as to pare the heel without leaving grooves therein. While
discs c, d, e may respectively be formed of or armed with emery, soap stone, and
sand paper or other suitable abrading material. E is a shield or cover which partially
surrounds the discs.
The discs are driven at a high speed, say from two to four thousand revolutions per
minute a rotary motion being conveyed to the shaft a from any convenient source
through pullies F F F and belting F³.
After the heel has been pared by the machine described in the herein before
mentioned specification, it is submitted to the action of the disc which brings it
almost to its finished state, when it is submitted successively to the actions of
discs c, d, e without stopping the machine, or removing the boots or shoes to separate
machines for completing the smooth finishing.
The heel after being inked with any suitable heel ink may be again submitted to the
action of the smooth or finely faced discs d and e, or the sand paper disc e alone,
which discs by revolving at a high speed evolve a considerable degree of heat
causing the gum in the ink to fill the interstices of the leather thereby forming a skin
on the top of the leather which prevents the ink from striking into the heel, and also
enables a good polish to be easily and readily obtained.
Having now particularly described and ascertained the nature of the said
invention (as communicated to me from abroad), and in what manner the same is to
be performed, I declare that what I claim is :-
1. The manufacture and use of a machine, such as herein described for smooth
finishing the heels of boots and shoes consisting of any desired number of discs, such
as b, c, d, e mounted on a shaft and driven at a high speed, the peripheries of said
discs being profiled to the shape or contour of the heel, and provided respectively with
rasp teeth, or armed with emery, soap stone, or sand paper, substantially as herein set
forth.
2. In a machine for smooth finishing the heels of boots and shoes, the discs such
as b, c, d, e, having peripheries profiled to the contour of the boot or shoe heel and
provided or armed respectively with rasp teeth or burrs, or emery, soap stone, or sand
paper as and for the purposes herein set forth.
3. The general construction and arrangement of the various parts forming the
heel smooth finishing machine as a whole, substantially as set forth and illustrated.
Dated this Twentyfifth day of September 1889.
