We JOHN KEATS of 15 Bergerstrasse, Frankfort-on-the-Main in the Empire of
Germany, Engineer, and SOCRATES KEATS of Eisenbahnstrasse, No. 1 (II Etage),
Leipzig in the Empire of Germany, Mechanical Engineer do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements on the paring and burnishing machinery
for which one of the present applicants obtained Her Majesty's Letters Patent
dated the 22nd day of November 1882 No. 5557, but part of the improvements are
also applicable to other machines of a similar type, and the invention consists in
providing means for holding and guiding the boot or shoe, so that the cutter
or burnisher shall not come into contact with the upper during the paring
and burnishing operations, and also in a novel arrangement of the burnishing
mechanism.
In carrying out our invention, we provide an adjustable holder in which the
boot or shoe is to be clamped, such holder being arranged so as to give the
requisite movements to the boot or shoe while being subjected to the operation of
paring and burnishing, and we also provide a pair of stationary guides, one of
which remains continuously in the crease between the upper and the heel during
the paring and burnishing operations, and the other, in combination with a
movable block or former, serves to determine the shape of the heel.
These guides are carried by adjustable brackets on the frame of the machine,
and are adjustably bolted thereto, so as to be capable of vertical and horizontal
adjustment. The outer guide has its guiding edge arranged in line with the
vertical axis around which the holder turns, and the inner guide receives the
pressure of a block or former carried by the boot clamp, and thereby determines
the amount of paring and shape of the heel during the paring operation, and
during the burnishing operation acts as a rest.
The holder consists of a curved arm terminating at its upper end in a fork, one
arm of which is adjustable. The fixed arm of the forked holder carries a
horizontal spindle on which the boot or shoe is placed. The adjustable arm is
provided with a pin or stud on which the block or former is loosely mounted.
The end of the spindle presses against the inside of the heel, and the block or
former presses against the outside. The boot or shoe is thus clamped in the
ΓΙ

page_text: holder, but it is free to turn axially therein. The curved arm of this boot holder
is pivotted or hinged at its lower end to the forked head of a vertical stem or axis,
which is mounted in a socket bearing carried by the frame. The hinge will allow
of the holder being rocked to and from the paring and burnishing tools during the
progress of the work, and the vertical stem being loose in its bearing, will permit
of the holder being raised or lowered to bring the heel to the level of the tool.
The vertical stem rests on the end of a rock lever, which is operated by a treadle.
The socket bearing we make adjustable laterally, so as to bring the heel into the
position necessary for the guiding edge of the outer guide to enter the crease of
the boot when pressed towards the tool.
The burnishing tools are mounted on the outer ends of a pair of shafts, which
are arranged in line, and carried in sleeve bearings bolted onto opposite ends of
a box frame carried by the frame of the machine. The inner ends of these
shafts carry cranks, the pins of which are furnished with bowles which enter a
peripherical serpentine groove formed in a cam carried by a transverse shaft
placed between the two crank shafts. This shaft also carries a pulley by which
it receives rotary motion by means of a band from an overhead shaft. The
serpentine groove of the cam communicates a rapid axial reciprocating motion to
the pair of shafts carrying the burnishing tools, and the tools themselves receive
a similar movement for the purpose explained in the Patent before mentioned.
One of these tools may be of suitable form for use in burnishing the soles of boots
and shoes, and the other for the heels. To the heel burnishing side of the machine
we adapt a boot holder and operating treadle as above described. The head of the
heel burnishing tool we prefer shall, in shape, conform somewhat to the contour of
the heel to be burnished, and the tool is carried by a stem and pin fitting into the
tool holder in the ordinary manner.

Improved Machinery for Paring and Burnishing Boot and
Shoe Heels.
We JOHN KEATS of 15 Bergerstrasse, Frankfort on the Main, in the Empire of
Germany, Engineer, and SOCRATES KEATS, of Eisenbahnstrasse No. (II Etage)
Leipzig, in the Empire of Germany, Mechanical 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 relates to improvements on a patent granted to one of the
present applicants for Improvements in machinery for triming the soles and heels
of boots and shoes bearing date November 22nd 1882 No. 5557.
The present invention relates mainly to novel means for presenting the heel of
the boot or shoe submitted to the finishing process in all its necessary positions, to
the cutter for paring, or to the burnishing tool for burnishing without risk of
cither the cutter or the burnisher injuring, or even touching the upper.
To this end we clamp the boot in a novel construction of holder, capable of
receiving the movements to which it may be requisite to subject the boot while
under the operations of paring or burnishing; we also provide two guides between
which the cutting or burnishing tool is situated. One of these guides is intended
to enter and remain in the crease between the heel and the upper during the
movements imparted to the heel of the boot or shoe. For this purpose, its guiding
edge is arranged in line with the axis of the vertical stem which carries the holder.
The other guide receives the pressure of the block or former or that' part of the
clamp that bears against the tread of the heel and it thereby assists in giving the
desired shape to the heel during the cutting operation. As the profile of the heel
varies greatly, the heel requires, when presented to the cutting or burnishing tool,
a continuous change of position, not only axially but horizontally as well as
vertically if the paring is to be performed by one form of cutter or the burnishing
by one form of burnishing iron; these changes of position in the work presented"
to the tools in our machine are obtained by constructing the support in which the
boot or shoe is mounted as hereinafter described so as to be capable of :-
1st moving in a vertical direction to bring the heel up to the level of the
working tool and to lower said heel at will.
2nd rocking on a horizontal axis to bring the heel into contact with the
working tool.
3rd moving around a vertical axis to bring the axis of the heel into different.
angles to the axis of the tool.
These movements are obtained 1st by a treadle 2nd by means of a spring or
weight pressing towards the tool, and controlled by a guide and former; and 3rd by
turning the boot holder and its stem by hand in its vertical support.
Besides these movements, the boot or shoe is free to be turned by hand with the
spindle of its holder, in order to present the sides and back of the heel to the
paring tool or burnishing tool as the case may be.

page_text: The paring tool consists of a rotary cutter formed with tangential blades in the
manner described in the specification of a patent granted to one of the present
applicants and bearing date Feb 3rd 1885. No. 1498.
The burnishing tool receives a reciprocating motion the same being derived from
a rotary cam having in its periphery a serpentine groove for receiving the bowl
of a rock shaft on which the burnishing tool holder is mounted.
In the accompanying drawings our invention is shewn at Figs. 1 to 6 as applied
to a compound finishing machine.

A A is the framing of the machine carrying in sleeve bearings A¹ A¹ the cutter
shaft B, C is the rotary cutter or paring tool, D is a boot holder hinged to a
stem E, which is capable of turning and sliding in a socket f formed on the end
of a horizontal slide F, carried by a bracket arm A³ projecting from the main
frame A. This stem is carried by the adjustable slide F, to permit of its
adjustment relatively to the position of a guide fitted to the head of the machine,
and intended to enter the crease and so determine the position of the boot to be
operated upon by the cutter.
The boot holder D branches at its upper part into two arms D¹ D² between
which the boot heel is clamped.-The arm D¹ carries a spindle d, mounted loosely
therein and fitted at its inner end with a block which enters the boot at the heel
and bears on the inner side thereof.-The arm D2 is adjustable to and from the
arm D¹ by means of the traversing screw d¹ and carries a pin d in line with the
spindle d. On this pin is mounted loosely the block or former d³ which bears
against the tread of the boot heel and when the arm D is screwed up by the
traversing screw d', the boot heel will be clamped between the block on the
spindle d inside the boot, and the block or former d³ outside the heel, it being at
the same time free to turn on its axis.-The holder or support D for the work is
hinged by the horizontal pin e to the forked head of the vertical stem E.-This
arrangement admits of the boot holder D being moved to and from the paring or
burnishing tool, and by means of a weight D³ of being held against the tool.-The
cord by which this weight is connected to the holder is passed over a guide pulley d'
mounted on the bracket A².
In order to limit the movement of the holder upon its hinge pin, it is fitted with
a stop pin e¹ which passes through a short segment slot formed in the forked end
of the stem E to receive the stop pin.
The slide F in the socket of which the stem E is supported, is mounted in
horizontal guides in the bracket A2, and is adjustable by the turning of a threaded
nut or hand wheel f' carried by a clip fa on the bracket A² and working on a
threaded pin f¹ with which the slide is fitted.
Underlying and bearing against the lower end of the stem E is one end of a
rock lever G, the fulcrum of which is carried by a lug projecting from the socket f
of the slide F. The opposite end of this rock lever is connected by a link with a
treadle H, by depressing or releasing which, the stem E with its boot holder D,
can be raised or lowered, at will.
I and J are vertical guides see Figs. 4, 5 and 6 the one for entering the crease
of the boot or shoe and determining the position of the same with regard to the

page_text: cutter, and the other serving as a stop for the block or former d³ to roll over while
gauging the shape to which the heel is to be cut. The guide I consists of the
chamfered vertical edge of a crank-shaped plate. This cranked plate is slotted to
permit of its being bolted adjustally to the outer end of the bracket I' which is
adjustably secured to the sleeve bearing A¹ by the screw i and nut ¹. Thus
an adjustment is secured for the guide I in two directions to suit both the
diameter and the length of the cutter. This guide is intended to form the fulcrum
on which the boot is rocked when presented to the cutter, and for that purpose
it is maintained as nearly as possible in the line of the axis of the holder stem,
and always in the plane of its axis.-The guide J is a somewhat similar plate
bolted to the bracket J, and secured on the sleeve bearing by the same means
as the bracket 11-The edge of the guide J is rounded (as shown best at Figs. 6
and 6), to present a good bearing surface to the block or former d³ whatever
inclination the former may take with respect to its bearing surface.
The boot or shoe heel which is to be operated on, having been clamped firmly in
the manner described is brought up to the level of the paring tool C by the operator
placing his foot on the treadle H and depressing it. This will rock the lever G
and raise the stem E with its holder D to the required height; the weight D³ will
then draw the holder carrying the boot towards the cutter, the guide I entering
the crease between the heel and the upper.-The clamp may then be turned, as the
paring proceeds axially by the aid of the spindle d, which is provided with a
handle for the purpose, or the holder may be moved round on its vertical stem E,
or both motions may be carried on simultaneously. The guide I, from its position
with respect to the cutter, forms a guard for the upper, securing it against being
injured by contact with the cutter and it is adjusted so that its guiding edge shall
correspond in position as nearly as possible with the vertical axis of motion of the
holder D.This will remove all tendency for the guide to leave the crease while
the boot is being turned about during the paring operation, as will be understood
on inspecting the diagram views Figs. 6 and 6°.-In presenting the back of the
boot heel and one side of the same to the paring tool, it will be seen that the
block d³ will rock on the end of the pin d as the boot changes its position,
the block being hollowed out to admit of this rocking motion.-The boot is held to
the cutter until the block d³ comes into contact with the guide J, when the action
of the cutter will cease, until a further portion of the heel is presented to its action
by turning the clamp as already explained.--The size and shape of the block d³
thus determines the shape to be given to the heel.
The burnishing machine is illustrated at Figs. 10, 11 and 12.
Fig. 10 shows in elevation, a burnishing machine constructed according to our
invention, and Fig. 11 is a plan of the same.
Fig. 12 shows in full size the burnishing tool holder and guides, and a portion of
the boot holder or clamp with the boot in position.
A is a standard of cast iron, to which is bolted a rectangular box framing A*,
carrying at either end a horizontal sleeve bearing A¹ for the reception of the short
shafts B. B*.-These shafts are furnished with burnishing tools CC at their outer
ends, and carry at their inner ends crank arms B¹.-These arms B¹ are furnished
with pins and bowles b, which enter the serpentine groove k of a cam K, and
receive therefrom a reciprocating motion for transmission to the burnishing tools.
The cam K runs loosely on a transverse fixed shaft K¹ carried by the box frame A*.-
Fitted to the cam is a driving pulley K², which receives motion by a band from an
overhead rotating driving pulley. It will now be understood that as rotary motion
is imparted to the grooved cam K, the crank arms B¹ will communicate an axial
reciprocating motion to their respective shafts B, B*, and thereby operate the
burnishing tools.-The burnishing tool-holder C, on one side of the machine, is
similar to that shown and described in the patent of 1882 before referred to, and
carries a tool suitable for burnishing the edges of boot soles.-During this operation
the boot or shoe is held up to the tool by the attendant.-The burnishing tool
holder C, at the other side of the machine is furnished with a tool c specially

page_text: designed for burnishing the heels of boots and shoes.-The shape of this tool which
conforms somewhat to the profile of the heel to be burnished is clearly shewn in
the enlarged plan view Fig. 12.-D is the boot holder or clamp, the construction of
which is practically the same as that described above with reference to the paring
machine, see Figs. 7, 8 and 9.-The means for adjusting the horizontal position of
the holder is however slightly modified.-In this instance the bracket arm A³ is
made hollow to receive the stem F, which carries the socket piece f, and is free to
slide in the bracket arm.-Beside the hollow in the bracket arm for receiving the
sliding stem, and parallel thereto, is a tapped hole for receiving the traversing
screw f¹-This screw passes freely through a lug on the socket piece f, and carries
a hand wheel, the turning of which will adjust the position of the socket relatively
to the bracket arm, a collar or shoulder being formed on the screw stem bearing
against the back of the lug.-This arrangement brings the hand wheel within
convenient reach for the workman for adjusting the position of the holder.-It will
be seen by the enlarged view of the parts at Fig. 12, that the two guides I and J
are mounted on the sleeve bearing A', so as to be capable of adjustment in two
directions as in the paring machine.
The manner of using this boot holder, after a boot or shoe has been clamped in
it, in order to present the heel to the burnishing tool, is similar to that already
described with respect to the paring operation.
We have shown this invention applied to two separate machines for convenience,
-but it will be evident that the paring and burnishing tools may be combined in
one machine if desired.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The arrangement of machinery above described with reference to Figs. 1 to 6
inclusive for facilitating the paring of the heels of boots and shoes.
2. The arrangement of machinery above described with reference to Figs. 10
to 12 inclusive for burnishing boot and shoe heels.
3. In combination with adjustable guides operating as above set forth, the
hinged swivelling clamp-holder, constructed as described with reference to Figs. 7
to 9 inclusive and operating as above set forth.
