I ROBERT HEAP SOUTHALL of 18 Chapel Lane Headingley Leeds in the County
of York Machine Maker do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINERY FOR PARING OR TRIMMING THE HEELS OF BOOTS
& SHOES to be as follows:—
My object is to hold a boot or shoe heel firmly on the top of a fixed pedestal
supplied with a proper template or pattern & pull a suitable cutting tool by means
of a spring or springs against the edge of the said boot heel, towards its centre and
thereby cause a shaving to be cut therefrom by making the said tool travel from
one corner of the heel, round the back to the other corner. To accomplish this
I construct a suitable frame & in a suitable place secure a pedestal. This pedestal
acts also as a stud for carrying a bevel wheel. On the top of the pedestal I place
a template upon which I place the heel to be pared & secure it by some downward
pressure brought to bear upon the heel from the inside of the boot or shoe such as
a screw. To the bevel wheel I attach in joints two vertical levers one for carrying
the paring tool, & the other for carrying springs used for forcing the tool towards
the centre. The tool works on centres suitably placed in a jointed frame & is
supplied with points to keep the blade at a cutting angle. The jointed frame is
made to adapt itself to any form of heel. I turn the machine by gearing another
bevel wheel into the one already mentioned and key it to a driving shaft in proper
bearings which shaft I turn by means of an ordinary winch handle or any other
suitable contrivance.

I Robert Heap SOUTHALL of 18 Chapel Lane Headingley Leeds in the County
of York, Machine Maker, do hereby declare the nature of my invention for
"IMPROVEMENTS IN MACHINERY FOR PARING OR TRIMMING THE HEELS OF BOOTS
& SHOES" 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 of Improvements in Machinery for paring the heels of
boots & shoes and will be clearly understood by the following description thereof,
reference being had to the accompanying sheet of drawings and the letters of
reference marked thereon.
Fig. I is a side elevation of my machine. I construct a frame A for carrying
the various arrangements. In a proper position on this frame I secure a fixed
pedestal B on which I place as on a stud the bevel wheel C. This is geared
into the bevel wheel D keyed on the shaft E which works in bearings in the
frame A and is turned by the winch handle F. On the pedestal B and above the
bevel wheel C I place the slotted template G shewn seperately in Fig. 13. against
which works the end of the thumb-screw H. The object of the said template &
thumb screw being to give a proper form to the seat of the boot K and a proper
pitch to the heel thereof as the said template can be moved backward and forward
having a slot L Fig. 13 by means of the rod M with screwed end and handwheel N
working on the screw. This causes the tool O and tool frame P to slant in any
required direction. I sometimes cast a groove y¹ in the template G. like that
shewn in Figs. 14 and 15. In this case I dispense with the springs Q and sub-
stitute a roller to work in the groove. I keep the template G in its place by the
collar R. Above this collar and on the pedestal B I place the template S shewn
seperately in Figs 5, 6 and 7. The pedestal B being turned down to form a
shoulder for it to rest upon. The object of this template is to give shape to the
top piece of the boot heel through the roller T vertical lever U, tool frame P and
tool O. I cast also with the template S but above it the fixed cam V which
I use for giving a proper angle to the knife W in the tool O through the regulation
screw X shewn distinctly in Figs. 2, 3 and 4. By being cast together the tem-
plate S and fixed cam V can be removed easily by merely lifting off the pedestal B
when any different shape or size of heel is required to be pared. The said tem-
plate S and cam V are kept steady by means of the wrought-iron connection
piece Y with a hole bored in the end to fit on the pin Z. I use the steel pin a¹ to
facilitate the fixing of the boot heel in its proper position. This pin a¹ I place
exactly in the centre of the top surface of the template S cam V and wrought iron
connection piece Y as shewn in Figs. 6 and 7 and I use a metal plate Fig. 12 with
the hole b¹ bored in the centre for the purpose of making a hole in the right place
of the leather top piéce of the boot heel before it is pared. By placing that hole on
the tapered steel pin a' the boot heel is certain to be fixed in a proper and central
position K is a boot so placed and held firmly in position by the screw c¹ working
in the boss d¹ fixed in the frame A. On the casting el bolted to the bevel wheel C
I hinge the vertical lever f¹ on the centres z¹ and the said vertical lever Fig. 11
I use for drawing by means of the springs gl the opposite vertical lever U towards
the centre of the pedestal B. To do this and gain sufficient power I use the angled

page_text: lever shewn in Fig. 8. The end h¹I place in the socket and press the handle
downwards till the pawl falls into the notch m¹ cut for its reception I then
remove the lever and the pawl holds the various parts in position till the paring
operation is completed when I again repeat the process to liberate the pawl. The
vertical lever UI hinge to the casting n¹ at the centres 211 the said casting is
slotted to enable it to be moved either nearer or further from the centre of the
pedestal B and thereby make it suitable either for a tapered or a straight boot heel.
I use the slide O¹ which carries the roller T which works when in working position
against the template S for the purpose of giving form to the top piece of the boot
and draw it backwards and forward by means of the grooved screw pl which works
in a vertical slot q₁ for the purpose shewn at Fig. 9. By means of the slide o² I am
enabled to make the boot heel either larger or smaller at pleasure for by screwing
up the screw p¹ the tool is drawn further from the boot heel and by unscrewing it
is brought nearer. The vertical lever U may therefore be considered as a movable
platform, which moves round according to the shape of the template S against
which it is drawn by the force of the springs g₁ In this manner I give shape to
the top piece of the boot heel, but as the seat is of a different form, I find it
necessary to make the joints 1 in which I work the tool frame P eo that in reality
it becomes a lever the centres being the fulcrum and the end of the thumb-
screw H being one end. The screw H is kept against the template G by the
springs which is drawn tight in the same manner and at the same time as the
springs g The end of the screw H working against the template G must there-
fore give shape to the top end and to the seat of the boot. The tool and tool
frame or holder are shewn in Figs. 2, 3, and 4. P is the holder or frame for
carrying the tool O and works in the centres 71 in the vertical lever U. Through
the lower end passes the thumb screw H, the end of which works against the tem-
plate G. The tool itself works in the centres t' t¹. The tool O I cast in brass or
some other suitable metal and of a suitable form. To this I secure the knife. The
centres t¹t on which it works I place about a quarter of an inch behind the
cutting edge so that when it begins to cut the leather, it has a tendency to turn
round. In doing so the regulation screw ✗ comes in contact with the fixed cam V
and this keeps the knife at a proper cutting angle. The regulation screw I place
about five eights of an inch in advance of the cutting edge of the knife and cause
it to suit large or small circles by the form I give to the fixed cam V. To protect
the upper of the boot from being injured by the knife WI construct the guard u¹
which I fasten to the lever v¹, in the proper place of which I secure the stud w₁
which I place in the bearing bored for it in the tool block O. The spring a¹ I use
for keeping the guard in its proper working position.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to Le performed I declare that what
I claim is
First. The general arrangements and construction of the machine.
Second. The pedestal B with templates G and S the cam V and the pointed
steel pin a as shewn in the drawing.
Third. The vertical lever U, working in the centres 211, slide o¹ and roller T in
connection with the springs g₁ and opposite vertical lever f¹ and pawl
notch m¹.
and
Fourth. The arrangements of the tool frame and tool, particularly the regula-
tion screw X and guard u¹ lever v₁ and spring ¹ and thumb screw H.
