PROVISIONAL SPECIFICATION.
Improvement in Heel Burnishing Machines.
I, HENRY WALTER PEAL, of 487 Oxford Street, London, Shoe Manufacturer,
do hereby declare the nature of this invention to be as follows
:-
My invention consists in applying to a heel burnishing machine an apparatus
by which boot heels may be accurately set in relation to the movement of the
burnishing iron.
To the "jack" or boot holder I apply fingers or jaws preferably connected
together in such a way that whatever movement is communicated to the one shall
be likewise imparted by it to the other.
These jaws engage the boot heel preferably at the corners of the breast and
hold it while the "jack" is being cramped upon the boot. They are then opened
away from the boot heel to make way for the burnishing iron to operate.
The fingers may be mounted upon short shafts in bearings provided upon the
"jack" frame and connected together by a pair of toothed quadrants or an
equivalent arrangement so that in whatever position one jaw or finger may be
placed relatively to the centre upon which they both open and close the other
jaw or finger shall assume a similar position upon the opposite side of the same
centre.

Improvement in Heel Burnishing Machines.
I, HENRY WALTER PEAL, of 487 Oxford Street, London, 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 :-
My invention consists in applying to a heel burnishing machine an apparatus by
which boot heels may be accurately set in relation to the movement of the
burnishing iron.
To the "jack" or boot holder I apply fingers or jaws preferably connected
together in such a way that whatever movement is communicated to the one shall
be likewise imparted by it to the other.
These jaws engage the boot heel preferably at the corners of the breast and
hold it while the "jack" is being cramped upon the boot. They are then opened
away from the boot heel to make way for the burnishing iron to operate.
"
The fingers may be mounted upon short shafts in bearings provided upon the
"jack
frame and connected together by a pair of toothed quadrants or an
equivalent arrangement so that in whatever position one jaw or finger may be
placed relatively to the centre upon which they both open and close the other
jaw or finger shall assume a similar position upon the opposite side of the same
centre.

page_text: My invention is illustrated by the accompanying drawings in which :-
Fig. 1. is a side view and
Fig. 2. is a front view shewing my improvement.
Fig. 3. is an explanatory diagram.

To the "jack or boot holder a Figs. 1. and 2. which may be of any of the
usual forms used in heel burnishing machines. I apply fingers or jaws 66¹ which
are mounted on short shafts cc'in bearings d d and have notches e el at their
upper ends to receive the corners ffl of a boot heel g. These jaws bb³ are
connected together by toothed segments h h mounted on the shafts cc' in such a
way that if one of them as b be placed with its notch e in contact with one corner
of a boot heel g the other jaw will be caused to take up a similar position on the
other corner of the heel a which will thus be held centrally in the "
'jack a while
the same is closed so as to hold the boot in the usual well known manner. After the
boot is cramped fast in the "jack" a the jaws bb' are opened into the position b³ ³
shewn by the dotted lines so as to leave room for the burnishing iron i to operate
about the boot heel g which it does in the directions of the arrows from the position i¹
to the position 2 and back again as shewn in dotted lines.
"
"
The position of the heel g and the amount of the angular movement of the
" iron
i are so set with reference to the centre j (see Fig. 3.) about which the
angular movement of the "iron" i takes place that on a medium sized heel g' g¹ q¹
the "iron" is at the same distance outwards from the centre, when at the top in
the position as when in either of the positions or which are the two extremes
of its angular movement and as in changing from large heels as g³ g² g² to small
heels as ggg the ion (when in these extreme positions i¹) will close in on the
radial lines kit is necessary in order that the "iron" i shall burnish up to
without overrunning the corners ff¹ that the notches e e¹ should close on lines as
nearly as possible parallel to the radial lines k k and this object is attained by
placing the shafts e c¹ in such position that the portion of the arcs m m³ through
which the notches e e¹ are moved in setting the different sizes of heel (from the
largest g to the smallest ³) are as nearly as possible parallel to the radial
lines k k'.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
The apparatus applied to a heel burnishing machine for accurately adjusting
the boot in relation to the movement of the burnishing iron, substantially as
described.
