Improvements in Machines for Burnishing the Heels of Boots.
I WILLIAM HENRY DORMAN of The Hawthorns Newport Road Stafford in the
County of Stafford Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to machinery or apparatus used for burnishing or polishing
the heels of boots and shoes and consists of improvements in the ordinary con-
struction of heel burnishing machines and is especially applicable to that kind of
heel burnishers commonly known as the Tapley Burnisher.
The machine consists of a column upon the head of which is mounted a hori-
zontal spindle which carries hinged to it a lever pressed upon by a spring.
On the free end of the lever is mounted the burnishing iron.
The horizontal spindle receives from suitable gearing a reciprocating rotating
motion thro. part of a revolution thus carrying the burnisher backwards & forwards
round the boot heel.
The boot is carried on a frame known as a "jack" which is so connected to the
machine that it receives a suitable backwards & forwards motion so as to bring
every part of the heel under the action of the burnishing iron.
The object of my invention is to automatically regulate the pressure of the
burnishing iron upon the boot heel, also to improve the construction of the jack or
part which carries the boot and of the vibrating parts in connection with the
burnishing lever.
For the purpose of regulating the pressure of the iron upon the boot heel I
mount on a vertical slide a cam at the top part or head of the column in such a
position that the horizontal spindle before mentioned passes through it and to the
lever carrying the burnishing iron I attach a bearing piece by means of a subsidiary
lever and spring.
This bearing picce is pivotted at one end in the subsidiary lever and adjustable
at the other end so that one edge of it may be set either parallel to or at any
desired angle with the centre line of the horizontal spindle. The edge of the
bearing piece bears upon the cam to which it is held in close contact by the
pressure of the same spring which keeps the burnishing iron pressed against
the boot heel.
The vertical slide carrying the cam is mounted in turn in a horizontal slide
lying parallel with the spindle and attached to the column head.
Lying across the machine at the rear is a rocking shaft which by a connecting
rod gives the backwards and forwards movement to the "jack" carrying the boot
(as described in the Specification of former Letters Patent dated 18th Feb.
A.D. 1889 No. 2811).
Upon this rocking shaft I mount a cam and from it by means of a rod and levers
I make a connection to the horizontal slide at the column head and from the same
or another cam I make a connection also by means of rod and levers to the vertical
slide.
The cam upon the rocking shaft is adjustable so that the times of its move-
ments may be varied and by altering the position of the joint pins in the levers
which connect to the rods the amount of movement of the horizontal and vertical
slides may be regulated.
The above named cam on the head of the machine is approximately of the same
shape as the heel of a foot and as the bearing piece moves around upon it the outer
free end of the burnisher lever and the burnishing iron which it carries move con-
formably to this shape. If the bearing piece be set parallel to the centre line of .

page_text: the horizontal spindle this movement will not be varied by the to & fro movement
of the horizontal slide and if the bearing piece be set at an angle with the centre
line of the horizontal spindle the movement of the burnishing iron will be varied by
the movement of the horizontal slide and will be varied more or less accordingly as
the inclination of the bearing piece and amount of movement of the horizontal
slide are more or less.
The movement of the vertical slide and cam acts directly upon the bearing piece
and lifts the lever & burnishing iron at the upper part of the stroke.
The improvement in the construction of the jack or part which carries the boot
is as follows. Instead of varying the angle of the jack by means of a hinged joint
and cramping screw I provide means for varying the angle of the top piece pad or
part which bears upon the top piece of the boot heel by mounting the same upon a
pivot and I cramp the said pad with a screw or otherwise in any desired position to
suit the boot heel being operated on so that such boot heel may be presented
properly to the burnishing iron and allow the iron to finish the heel right up to the
seat but not to come forward on to the upper.
I simplify the construction of the jack by carrying the two jaws of it upon a
common pivot at the base of the machine and doing away with the slide and side
guides. The pivot is made long to give lateral support and resist the side thrust
of the burnishing iron.
To enable a higher speed to be maintained and so increase the output of the
machine I balance the crank disc and other parts and I employ springs to
absorb the momentum of the vibrating arms and levers at the two ends of the
stroke.

COMPLETE SPECIFICATION.
Improvements in Machines for Burnishing the Heels of Boots.
I WILLIAM HENRY DORMAN of The Hawthorns Newport Road Stafford in the
County of Stafford 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 :-
My invention relates to machinery or apparatus used for burnishing or polishing
the heels of boots and shoes and consists in improvements in the ordinary con-
struction of heel burnishing machines and is especially applicable to that kind of
heel burnisher commonly known as the Tapley Burnisher.
The machine consists of a column upon the head of which is mounted a horizontal
spindle which carries hinged to it a lever pressed upon by a spring. On the free
end of the lever the burnishing iron is mounted. The horizontal spindle receives
from suitable gearing a reciprocating rotating motion through part of a revolution
thus carrying the burnishing iron from side to side round the boot heel. The
boot is carried on a frame known as a "jack" which is so connected to the machine
that it receives a suitable backwards and forwards motion so as to bring every part
of the heel under the action of the burnishing iron.
Hitherto it has been found difficult or impossible to impart a high degree of even
finish to a boot heel on machines as ordinarily constructed particularly when such
heels have much curvature or swell in the vertical contour and especially if the
curve at the back of the heel differs materially from that at the side. Such a heel
is usually said to have much pitch. This difficulty of imparting an even finish
arises from the irregular pressure of the burnishing iron upon the boot heel caused
by the boot heel itself having to move the iron outwards against the pressure of the
burnishing lever spring as the iron gradually travels over the swelled part of the
heel. This irregularity of pressure is also liable to mar the appearance of
the heel by causing the surface to crack.

page_text: One object of my present invention is to automatically regulate the pressure
of the burnishing iron upon the boot heel.
This I accomplish by mounting a cam upon a vertical slide at the head of the
machine so that the horizontal spindle before mentioned passes through it and to
the lever which carries the burnishing iron I attach a bearing piece by means of a
subsidiary lever and spring. This bearing piece is pivotted at one end in the
subsidiary lever and is adjustable at the other end so that one edge of it may be
set either parallel to the centre line of the horizontal spindle or at any desired
angle with it. The edge of the bearing piece bears generally upon the cam, being
held thereto by spring pressure. The vertical slide is mounted in a horizontal
slide lying parallel with the horizontal spindle and attached to the column head.
From the rocking shaft which gives the automatic backward and forward movement
to the "jack" -as described in the Specification of former Letters Patent granted
to me and dated the 18th February A.D. 1889 No. 2811-I make a connection to
the horizontal slide so as to give it also a backward and forward movement and
from the same rocking shaft I make a connection to the vertical slide so as to give
it an up and down movement, introducing an adjustable cam to regulate the time
at which the movements shall be made to commence.
The above named cam on the head of the machine is of a horse shoe form and
has an outline somewhat like a heel and as the bearing piece moves around upon
it the outer free end of the subsidiary lever moves conformably to this shape. If
the bearing piece be set parallel to the centre line of the horizontal spindle this
movement will not be varied by the to and fro movement of the horizontal slide
and if the bearing picce be set at an angle with the centre line of the horizontal
spindle the movement of the subsidiary lever will be varied by the movement of
the horizontal slide and will be varied more or less accordingly as the inclination
of the bearing piece or amount of movement of the horizontal slide are more
or less.
The movements of the subsidiary lever by altering the tension of the spring by
which it is connected to the burnishing lever affect the amount of pressure exerted
by the burnishing lever spring and consequently the pressure of the burnishing iron
upon the boot heel.
The upward vertical movement of the horse shoe shaped cam acts directly upon
the bearing piece and lifts the subsidiary lever and as this lever is as before said
elastically connected to the burnishing lever there is a tendency to ease up or
partially lift the burnishing lever also, so that instead of the swell on the back of
the boot heel having to force up the burnishing iron and lever against the pressure
of the burnishing lever spring the upward movement of the iron is assisted by the
upward movement of the horse shoe shaped cam.
Another part of my invention consists in an improvement in the construction of
the "jack" or part which carries the boot.
In order that the burnishing iron shall burnish the boot heel right up to the seat
and yet not pass over on to the boot upper it is necessary that the seat of the boot
heel shall coincide exactly with the path of the burnishing iron at the time this
part of the heel is being operated upon, and so that this coincidence of the heel seat
and path of the burnishing iron may be exactly arrived at I provide means for
varying the angle of the top piece pad, or part which bears upon the top piece of
the boot heel, by mounting the same upon a pivot and I cramp the said pad with a
screw or otherwise in any desired position to suit the particular boot heel being
operated upon.
I may also support the "jack" at its base upon a shaft or pivots at or near the
base of the machine and do away with the slide and side guides. The supports
being far apart so as to resist the side thrust of the burnishing iron.
My invention is illustrated by the accompanying drawings in which
Fig. 1. is a side elevation of the machine.
Fio 2 is a front elevation.

"A is the base and "B" the column to which the various parts of the machine
are attached. The bracket "C" is furnished with bearings "D" "D" in which
revolves the main shaft "E." F"
"F1" are the driving pulleys and "G" is the
crank disc secured on the inner end of the main shaft "E" and having a radial
slot in which the crank pin "H" may be adjusted and cramped fast. The crank
pin "H" gives motion by means of the connecting rod "I" to the bell crank
lever "J"which is mounted on the pivot "K." The upper end of the lever "J
has a toothed segment "L" which gears with the pinion "M" secured on the rear
end of the horizontal spindle "N." The spindle "N is free to turn in the
bearings "O" "01" which are provided for it in the head of the machine. The
block "P" is fixed on the spindle "N" and has a pin "Q" on which hinges
the lever "R" which is free to turn upon the pin "Q in a direction radial to the
centre of the spindle "N." The balance weight "S" is attached to the lever "R"
having a clearance slot in its centre through which the spindle "N" passes.
In the above description the features of the machine generally resemble those of
the "Tapley Heel Burnisher as usually constructed.

زو
I now proceed to describe my improvements and shew how they are applied.
For the purpose of automatically regulating the pressure of the burnishing
iron upon the boot heel I provide the following arrangement. A cam
<< a" (see
Figs. 1. 2. 3. 4.) is fixed upon a vertical sliding bar "a" which is free to move
and down in a way
up
"a" provided for it in a sliding piece "a³." The sliding
piece "a" is arranged to slide horizontally in a way "a" provided for it in a
bracket "a" fixed to the head of the column "B." Passing through the column
head is a horizontal rocking shaft "a" upon which is secured a horizontal
lever "a" and a vertical lever "a"." The end of the horizontal lever "a" is
provided with a
pin and die block "a" and on the vertical sliding bar "a""
before mentioned is provided a horizontal slide-way "a" to slide upon the die
block "a."
The upper end of the vertical lever "a" is jointed by means of a connecting
rod "ato a pin "a" which is adjustable in a longitudinal slot on one side of the
lever "a" and the sliding piece "a" is connected by means of a rod "a" to a
pin "a" on the opposite side of the said lever "a¹³." The lever "a13" is secured
upon a rocking shaft "a" carried in a bearing "a" in the bracket "T" further
described hereafter. The rocking shaft "a" has secured to its other end a
lever "a" which is furnished with a roll and pin "a19" adapted to work in a
groove "a" provided for it in a cam "a"."
For the purpose of giving movement to this cam "a21" which operates the above
described pressure regulating arrangement I make use of the mechanism which is
provided for giving the automatic to and fro motion to the "jack
ર
as described in
the Specification of former Letters Patent granted to me dated Feb. 18th A.D. 1889
No. 2811, and which has already been referred to. This mechanism is as follows.
The main shaft "E" gives motion by a pair of gears """" or equivalent
means to a shaft "62" which is carried in bearings in the bracket "T." On
the shaft "2" is a worm 668699 gearing into a worm wheel "66" which is secured
upon one end of a shaft "67"revolving in a bearing "68" in the bracket "T."
Upon the other end of the shaft "" is mounted a heart cam "" which operates
upon a roll in the end of a lever "10" upon one end of a rocking shaft ""."
rocking shaft "1" is carried in a bearing "12" in the bracket "T" and has upon
its other end a lever "13" The boss "14" of this lever is adapted to receive the
cama" already referred to which is mounted so as to be capable of adjustment
and can be cramped fast in any desired position by means of a cramping screw "a"."
The cam "a" is made with a portion a24" of its groove "a20" the arc of a circle
struck from the centre of the shaft "the remaining portion "a" of the
groove "a20" being of such a form as will give the desired movement to the sliding
rr
The

piece "a" and the vertical sliding bar "a¹." The point "a23" in the groove "a20"
where the circular path "a24" ceases is the point where the movement of the
lever "a" will begin and as the position of this point "a23" can be varied by
means of the cramping screw a22" so as to allow a greater or less amount of the
travel of the cam " 21 to take place while the cam roll "a" is in the circular
part "a24" of the path "a20" so will the movement of the lever "a18" and con-
sequently of the cam take place carlier or later.
The pin "Q" which has been already referred to as carrying the lever " R"
serves also as a pivot for the subsidiary lever "c" which carries on a pin "c"the
bearing piece "2" which passes through slots in the levers "R" and C. The
under edge "3" of the bearing piece "c" lies ordinarily upon the edge of
the cama." The end "" is formed into the segment of a tangent wheel in
which works a worm ""carried in the lever "e" and provided with a hand
wheel "." By means of the hand wheel "" and worm "c" the edge "" may
be set at any desired angle with the spindle "N." The piece "" is fast upon
the spindle "N" and is shaped like an inverted T from the arms of which
extend springs "c" which are made fast to the lever "R" by adjustable
screws "" and serve to draw the lever "R" in towards the cam "a." A stem "lu"
is secured in the lever "R" and passes through a slotted hole in the lever ","
it is provided with a spring "ell" which bears down upon the lever "c" and can
be adjusted by the nut ""By screwing down the nut "e" the spring "ell"
is compressed and the connection between the levers "c" and "R" is made more
rigid while by unscrewing the nut "c1" to some extent the spring "c1" is somewhat
released and the connection between the levers "e" and "R" is made more elastic
so that the cam " a may thus be made to act more or less powerfully upon the
burnishing iron "" as may be desired. Hinged upon a pivot "3" is a lever ">
which carries the burnishing iron "." A small curved rack "c6" on the end of
the lever "R" is geared into by a worm "c17" carried in the lever "" and a
hand wheel 18 upon the worm "c17" serves to adjust the lever "4" and
consequently the burnishing iron "15" inwards or outwards to suit boot heels of
varying sizes.
22
To assist in driving the burnishing lever "R" to and fro and relieve the strain
upon the hinge pin "Q,' I provide a slotted driver "19" in which the burnishing
lever "R" works.
"
My improvement in the "jack" is as follows. In the jaw "d" of the "jack"
I provide a pivot "d" and upon this pivot I mount a piece "2" which I call a
top piece pad so that it can be set at any desired angle with regard to the line of
the seat "3" of the boot heel and there cramped by means of the screw "d*."
:>
The "jack" is constructed in the following manner. Passing through the
base "A is a horizontal shaft "e" free to turn in bearings "e"." Secured
to its ends are levers "3" "e" which carry a second horizontal shaft "e." The
jaw "d" and the main body or frame "" of the "jack are mounted upon
the shaft "e" on which they move freely. The treadle "" is pivotted in the
base "A" at "1" and its inner end "f" acts upon a screw "3" which passes
through the shaft "e" and can be adjusted therein by the hand wheel ""so as
to raise and lower the shaft "e" and consequently the "jack" which it carries.
The inner end "72" of the treadle "/" rests upon a stop "5" in the base "A"
when the treadle is not in use.

The frame" of the "jack" has a pivotted bearing

is furnished with a hand wheel ""by means of which the jaw "d" is caused
to approach or recede from the frame "d" for the purpose of holding or
releasing the boot. The rod "h" is fixed in the frame "" and carries the
hinged block "2" which goes inside the boot and takes against the insole so
as to oppose the pressure of the jaw "d." In the main body or frame "d"
of the jack" is a pin "i" upon which is pivotted the tubular connection "
in which the connecting rod ""slides, and in which the connecting rod "2"
"

page_text: may be held fast by the pin or cotter "3" being passed through a suitable
slot in both the tube ""and the rod "" by the operation of the handle "
to which the cotter "3" is attached. The rod "2" is connected to the curved
slotted lever "13" by the rod "" and a pin "," which is adjustable in the
slot "." The right and left coupling nut serves to join the rods "" and ""
and allow of adjustment in their lengths. This tubular connection
rods "2" 3" and slotted lever "13" as also the method of carrying the hinged
block"" are the same as described in my Specification No. 2811 A.D. 1889
before referred to. The "jack" is balanced by a weight "j" hung upon a
chain ""passing over a pulley "2" in the column "B" and attached to the
framed."

In the modification shewn in Fig. 5. the driving pulleys "F" and "F" are
outside the bearing "D" and the worm "" is mounted upon the main shaft "E."
The up and down motion of the cam
" is derived in a different manner as
follows. A piece "" is mounted upon a pivot "" in some fixed part of the
machine head and is provided with teeth ""adapted to work in a worm <3 "
which by revolving a hand wheel "" may be turned so as to raise and lower the
piece ""about its pivot "k" and consequently vary the angle of inclination of
the upper edge "" of the piece "." Upon the vertical sliding bar "a" is
mounted an adjustable slide"" which may be set higher or lower by a
screw "k" and which carries a roll "" arranged to take upon the upper
edge "" of the piece "k.” The rod a 14" is connected at one end to the
lever "a" which is in this case mounted directly upon the rocking shaft "," and
at the other end to the sliding piece "a" which is thus moved to and fro in a manner
as already described. The vertical sliding bar "a'," the slide "k" and the roll "48"
of course moving to and fro with it. If the upper edge "" of the piece "k" be
set level the roll "8" will roll to and fro upon it without raising and lowering the
cam "a" and if the edge ""be set at an angle the roll "8" will roll up and
down the incline and will raise and lower the cam << "
more or less according as
the incline is greater or less, while if the slide "" be set higher on the vertical
sliding bar "a" the roll "8" may be made to travel a portion of its distance
horizontally and without touching the edge "k" and the remaining portion, after
the roll "" touches the edge "" and until it leaves it again, will be made rising
and falling according as the inclination of the edge "k" is set.
The screw

a
"20" is adjustable up and down in the lever "R" by means of the
hand wheel "21" and in addition to the spring "ell" is provided with a collar "22"
which takes under the end of the lever "e" and raises or lowers the piece "c2"
from or towards the
cam so that the edge "3" of the piece "c2" may be
operated upon by the cam a sooner or later as may be desired.
In order that the machine may stop automatically when a boot heel has been
burnished I throw out from the heart cam "" a striking piece "Z" which with
each revolution of the heart cam "6" comes in contact with the end "1" of a lever
carried on a pivot "1" in the bracket "C" and by depressing the end "11" raises
the notch "" from the peg "" and thus releases the belt fork "" which is
pivotted at "." The weight of the belt fork lever handle "17" then causes the
belt to pass over on to the idle pulley "F" and so stop the machine. On raising
the handle "" the machine again starts and the notch 3 engaging with the
keeps the belt fork "" in position until the striking piece "/" again
comes round and trips the lever "."

If desired instead of attaching the striking piece "1" to the heart cam "19" I
may gear slower or faster to a special disc or wheel and attach the striking
piece "1" to it so as to cause the burnishing iron "e" to act either a greater or
fess number of vibrations upon the boot heel before the machine stops.
The "jack" in this modification is shewn not furnished with a treadle but the
frame "d" and the jaw "d" are carried on a common centre by the shaft"
fixed across the base "A" of the machine.

The gas is lighted and the burnishing iron properly heated. The cotter","
being withdrawn from its slot in the connection allows the "jack" to be drawn
away from the column "B" by the operator clear of the burnishing iron "c1" so
as to allow of the insertion of the boot in the "jack" which is then cramped fast
by turning the hand wheel "g." The "jack" is then pushed inwards towards
the column "B" until the top piece of the properly inked heel comes under the
burnishing iron "c" when the cotter "3 is pushed home in its slot by the
handle ""so as to couple up the "jack" to the machine. The machine is set
in motion and the burnishing iron "15" commences to vibrate from side to side
upon the surface of the boot heel. As the iron vibrates the "jack" is drawn
inwards by the operation of the heart cam "6" upon the levers "10" "613" and
connections """"and at the same time the cam 66 21 " commences to move
upwards and when the point "23" of the cam groove "a20" comes to the roll "19"
the levers "a18," "a13" will be set in motion and commence to draw back the cam
under the edge "3" of the piece "c2" which has been previously set at an angle of
inclination to suit the sides of the boot heel being operated on.
The cam
"21" is
so set and cramped by the screw "a" that the movement of the lever "a13" to draw
back the cam 66
a "shall commence at the same time as the commencement of the
swell of the boot heel begins to be operated upon by the burnishing iron " (18."
While the rod "a" draws back the sliding piece "a" and cam "a" the rod "all"
through the levers "a" and "a" pushes up
"which combined move-
ments of the cam "a" raise the piece "c2" and the lever "," which is elastically
connected to the burnishing lever "R" by the spring "c" further and further out
from the line of the centre of the boot heel as the latter is drawn by the operation
of the machine more and more inwards towards the column "B" until the burnishing
iron "1" is quite upon the seat of the heel and close to the upper of the boot.
the piece "2" has been set at the proper angle the burnishing iron "e18" will now
travel round exactly upon the heel seat without passing over on to the upper and
without failing to burnish the heel as closely up as possible to the upper.
This
takes place while the roll in the heart cam "" is at the point of least distance
from the centre of the shaft "67"after which as the heart cam ""continues to
revolve the "jack" will be moved outwards with the boot, the cam "21" will
descend and the reverse operations will take place until the burnishing iron "18"
is again at its point of commencement at the top piece of the heel. If the auto--
matic stopping arrangement, as shewn in Fig. 5, be employed the machine will
then be brought to rest, the "jack" may be disconnected by means of the hand
lever "" and by means of the hand wheel "g" the jaw "d" be opened and the
finished boot removed to make way for another.

If
وو
The machine as illustrated in Fig. 5" is operated in a manner almost precisely
similar only that instead of timing the cominencement of the motions of the cam "a"
by setting the cam "21" the timing is regulated by setting the piece "2" nearer
to or further from the cam "a" by means of the hand wheel "and by adjusting
the roll ""which is carried upon the slide ""nearer to or farther from the
piece ""by means of the screw "k"."
If desired the piece "k" may be carried upon the sliding bar "a" and the
roll upon an adjustable piece attached to a fixed part of the machine head.
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:
1. In a machine for burnishing the heels of boots the use of a mechanism in
which a cam, between which and the apparatus carrying the burnishing iron
relative motion automatically takes place, varies the pressure upon the burnishing
iron.
2. In a machine for burnishing the heels of boots and in which a cam is used for
the purpose of regulating the pressure of the burnishing iron the use of the

page_text: piece ""arranged to be acted upon by the said cam and which may be set at
various inclinations to suit the various inclinations of the sides of boot heels.
3. In a machine for burnishing the heels of boots and using a cam for regulating
the pressure of the burnishing iron the use of a lever "e" and spring ""for the
purpose of making an elastic connection between the piece "c2" and the burnishing
lever "R."
4. In a machine for burnishing the heels of boots and using a cam for the
purpose of regulating the pressure of the burnishing iron giving to such cam a to
and fro horizontal movement.
5. In a machine for burnishing the heels of boots and using a cam for the
purpose of regulating the pressure of the burnishing iron giving to such cam an up
and down movement.
6. In a machine for burnishing the heels of boots the use of a mechanism by
which the burnishing iron is made adjustable in relation to the burnishing lever in
a direction radial to the centre of the heel so as to suit various sizes of boot
heels.
7. In a machine for burnishing the heels of boots the use of a driver or guide
attached to the burnishing spindle for supporting the lever which carries the
burnishing iron against the lateral resistance of the burnishing movement.
8. In a machine for burnishing the heels of boots in which an automatic arrange-
ment is used for regulating the pressure of the burnishing iron the use of an
adjustable cam, or equivalent arrangement, for the purpose of determining the time
when such automatic pressure regulating arrangement shall come into action.
9. In a machine for burnishing the heels of boots and in which a cam is used for
regulating the pressure of the burnishing iron the use of a pivotted piece "k"
adjustable so that one of its edges may be set at any desired angle for the purpose
of giving an up and down movement to the said cam.
10. In a machine for burnishing the heels of boots and in which a cam is used
for regulating the pressure of the burnishing iron the use of a hand wheel " €21 "
screw 20 "and collar "22" or their equivalents for the purpose of adjusting the
position of the piece "2" in relation to the aforesaid cam.
ઃઃ
11. In a machine for burnishing the heels of boots constructing the top-piece
pad and parts in connection therewith so that the top-piece pad may be set at a
suitable angle relatively to the heel seat.
12. In a machine for burnishing the heels of boots pivotting the jack at or near
the base of the machine on points of support far enough apart to afford sufficient
lateral resistance to the side pressure of the burnishing iron without the employ-
ment of side guides.
13. In a machine as herein before described and illustrated for burnishing the
