PROVISIONAL SPECIFICATION.
Improvements in Burnishers for Finishing Boots and Shoes.
We SOCRATES KEATS, Mechanical Engineer, and CHARLES HORATIO KEATS,
Engineer, both of Stafford in the County of Stafford, do hereby declare the nature
of this invention to be as follows:-
The object of this invention is to effect the operation of burnishing the heels and
soles of boots and shoes with greater rapidity than heretofore, and that without
applying heat to the burnishers.
To this end, we use a rotating burnisher which will polish the surface submitted
to it without forming any lines thereon requiring to be subsequently removed.
The acting surface of our improved burnishers will in all cases take either a
helical, spiral or double spiral form, the contour of the burnisher corresponding
with the form on which it is required to act. We form the burnisher out of solid
metal, preferably of cast iron or steel, having determined beforehand the kind of
work to which it is to be applied. The acting surface, which takes the form of a
coil contracting in diameter at its ends, will be rounded so as to present no cutting
edge to the work, and, while in rapid rotation, the work will be pressed against it
and held firmly against a stop, in order to resist the drawing action of the
burnishing, surface, the tendency of the burnisher, from its construction, being to
move the work in the line of its axis of rotation.
This construction of burnisher although suited only to one special kind of work,
will, by the economy of its production, allow of various forms of burnishers being
made, to suit the various fashions and requirements of the trade.
The length of the burnisher should somewhat exceed the breadth of the work
to which it is to be applied, in order that no mark of the continuous burnishing
surface should be left on the work.

COMPLETE SPECIFICATION.
Improvements in Burnishers for Finishing Boots and Shoes.
We SOCRATES KEATS, Mechanical Engineer, and CHARLES HORATIO KEATS,
Engineer, both of Stafford in the County of Stafford, do hereby declare the
nature of this invention and in what mauner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this invention, like that for which protection was obtained by one of
us on the 28th of October 1892, No. 19403, is to effect the operation of burnishing
the heels and soles of boots and shoes with greater rapidity than heretofore.
To this end, we use a rotating burnisher which will polish and level the surface
submitted to it without forming any lines thereon requiring to be subsequently
removed. The acting surface of our improved burnishers will in all cases take
either a helical, spiral, or double spiral form, the contour of the burnisher
corresponding with the form on which it is required to act. Instead of the
burnisher being composed, as in the Application above referred to, of an adjustable
metallic coil, we form it out of the solid metal, preferably of cast iron or steel,
having determined beforehand the kind of work to which it is to be applied. The
acting surface, which takes the form of a coil contracting in diameter at its ends,
will be rounded, so as to present no cutting edge to the work, and while in rapid
077

page_text: rotation, the work will be pressed against it, and held firmly against a stop, in
order to resist the drawing action of the burnishing surface, the tendency of the
burnisher, from its construction, being to move the work in the line of its axis of
rotation.
In the accompanying drawing, we have shown three forms of our improved
burnisher, to illustrate the various kinds of work to which the invention may be
applied.
Fig. 1 is a front view of a burnisher mounted upon its shaft, and shaped to
burnish what are known as Wurtemberg heels.
Fig. 2 is a front view of a burnisher, shaped to burnish heels of the ordinary
type.
Fig. 3 is a compound burnisher consisting virtually of two distinct burnishers,
secured to one and the same shaft, the one burnisher being intended to burnish
the sole of a boot or shoe and wipe down the edges of the channel formed to
receive the stitches, and the other burnisher to burnish the waist of the boot or
shoe and the breast of the heel simultaneously.
A is the body of the burnisher, having an acting surface in the form of a spiral
thread a cast therewith, and having a contour or profile suitable for the work in
.hand.
The burnisher is by preference secured to its shaft B by inserting the latter in
a central hole in the former prepared to receive it, and therein fixing the same,
either by nuts c, as in Figs. 1 and 2, or pins c', as in Fig. 3.
The burnisher A¹ for levelling and burnishing the soles of boots and shoes
shown at Fig. 3, has a right and left handed thread a', working from the centre
outwards, so as to burnish and spread the sole in that direction, and to wipe down
the channels in the sole containing the stitches. d is the boot sole shown in
proximity to the double-threaded burnisher. e is the boot heel, in position for the
heel burnisher to act thereon.
As a variation, the spiral thread of the burnisher may be made undulating or
wavy, to give a kind of intermittent rubbing, like a hand burnisher, if desired.
In addition of the rotary movement of the burnisher, there may sometimes be
given to the shaft a reciprocating movement in the direction of the axis.
This construction of burnisher will be cheap as compared with the adjustable
burnisher of the earlier Application, and although suited only to one special kind
of work, the economy of its production will provide for various forms of burnishers
being made to suit the various fashions and requirements of the trade.
The length of the burnisher should somewhat exceed the breadth of the work
to which it is to be applied, in order that no mark of the continuous burnishing
surface should be left on the work.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved burnisher for the soles and heels of boots and shoes, consisting of
a solid body with a spiral, helical, or double spiral acting surface or thread, of a
contour to suit the work in hand, substantially as herein before described with
reference to the drawing.
