PROVISIONAL SPECIFICATION.
Improvements in Tools for Use in Burnishing the Soles and Heels
of Boots or Shoes.
I, JOSEPH GARRATT GRIMSLEY of Halford Street Leicester in the County of
Leicester Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in tools for use in burnishing the soles
and heels, foreparts; and waists, or setting the edges of boots or shoes and consists
in providing vibratory or rotary tools made of vulcanite, ebonite, woodite or the
like composition or combinations which by frictional contact with the boot shall get
hot without having to be heated like the steel irons now employed in all machine
and hand burnishing tools known at the present time.
To carry out my invention I take a block or blocks of material as above
mentioned of suitable quality and dimensions and cut it, to thes hape desired, if of
the circular shaped rotary type, adapted to polish the heels, the tool is shaped to
correspond to the peripheral curve of the heel, and is provided with screw threaded
holes if in blocks and shaft hole therethrough so that it can be readily fitted upon
a revolving shaft, and to a collar or guard thereon.
For circular rotary tools adapted to polish or burnish the fore-part edge, or
waist, the block of vulcanite or the like is cut to the size and width, and a lip cut
or turned up on one edge and the surface convexed to suit the pitch of the sole
edge, or waist and a hole made through so that it can be put upon a revolving
shaft ready for use. Another advantage of using these tools is that although they
get hot quicker than steel they do not sear or scorch the leather, and an operator
at a machine can alter the peripheral shape of the tool without removing it from
the machine.
Vibratory tools used for edge setting fitting in tool holders, either for hand or
machine work of whatever width or shape can be made of the materials or
compositions before mentioned and fitted in their holders, the same as steel
burnishing irons.
By this my invention I obviate the use of gas for beating the tools, and
the injurious effects proceeding from the operator inhaling such fumes while
at work.

COMPLETE SPECIFICATION.
Improvements in Tools for Use in Burnishing the Soles and Heels
of Boots or Shoes.
I, JOSEPH GARRATT GRIMSLEY of Halford Street Leicester in the County of
Leicester 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 tools for use in burnishing soles and

page_text: heels, waists, or setting the edges of boots or shoes and consists in providing
vibratory or rotary tools made of vulcanite, ebonite, woodite or the like
composition or combinations, but what is known as "vulcanized fibre" is
preferred.
It will be found that such tools can be kept hot without beating by gas or the
like that is to say; they shall by frictional contact with the boot get hot without
having to be heated like the steel irons now employed in all machine and hand
burnishing tools known at the present time.
That this invention may be clearly understood I have thought it necessary to
show by drawings accompanying this Specification the various shapes used in the
trade, and in which
Figure 1 represents a rotary heel burnishing tool A made of vulcanite blocks, or
"vulcanized fibre" sheets, and having augular cuts a made at intervals round the
periphery.
Figure 2 is a side view of a series of rotary edge tools all fitting together upon a
horizontal or other driving shaft.
Figure 3 represents a milled edged seat wheel with screw hole for securing same
to shaft.
Figure 4. shows a breast iron made in accordance with this invention.
Figure 5. represents a vibratory edge iron, either with solid or hollow shank (the
latter shown by dotted line) made of vulcanite or the like composition.
Figure 6 represents a rotary waist iron made in accordance with this invention.
Figures 7 and 8 are side and end views respectively of the rubbing blocks used
in "The Rockingham" machine, made in accordance with this invention.
Figure 9 shows part of a composite finishing machine provided with the
combination tools made in accordance with this invention.
The same letters of reference are used throughout the several views.
To carry out my invention I take a block or blocks of material as above
mentioned of suitable quality and dimensions, which is coloured red and black, to
be used for brown & coloured work, also black work; it is then cut to the shape
desired, if of the circular rotary type adapted to polish the heels of boots and shoes
"see Figure 1," the tool A is shaped to correspond to the peripheral curve of the
heel as usual, by cutting in a lathe, the screw holes B being provided so that it can
be readily fitted against suitable collars on a revolving shaft, or to a suitable
adjustable guard C thereon.
For circular rotary tools adapted to polish or burnish the forepart edge, or waist,
the block of vulcanite or the like having been cut to the size, and of the width
desired is provided by cutting or turning up a lip D on one edge and the surface
convexed E to suit the pitch of the sole edge, or waist, and the necessary hole B
made through to secure it upon a revolving shaft F when it or they are ready
for use.
Upon reference to Figure 9 it will be seen that a guide or guard C, also a rest G
is provided by which means the operator can by resting on the bar 9. alter the
peripheral shape of the tool without removing it from the machine.
In vibratory tools used for setting the edges or waist of a boot or shoe as seen in
Figure 5, made of vulcanized fibre, no cuts are necessary, and they can be fitted
in a holder or stem of a tool holder, whether of a machine or hand, and of whatever
width or shape and of the compositions or materials before herein described, the
same as if made of steel like those now in use.
Although tools made of the material or materials forming the said compositions
will get bot quicker than steel they do not sear or scorch the leather, and in
coloured goods are valuable upon this account.
But it is necessary sometimes when the machine is standing idle to induce heat
without wasting time the contact wire or spring H may be employed as seen in
Figure 9, for this purpose.
By this my invention I obviate the use of gas for heating the tools, and also

page_text: the injurious effects proceeding from the operator inhaling such fumes while
at work.
This to every one concerned will be a welcome advantage.
I do not confine myself to any shape or form of tool but to the advantage of
utilizing such compositions for all tools used in burnishing the soles, and heels of
boots and shoes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
In the process of burnishing the soles or other parts of boots and shoes, the
employment of a tool, or tools shaped out of moulded or cut material such as
vulcanite, vulcanized fibre, ebonite, woodite or the like composition or combinations,
forming the various rotary and vibratory tools illustrated in the drawings, and
others for the purpose substantially as described.
