I JOHN HENRY JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN BURNISHING MACHINES FOR USE IN THE MANUFACTURE OF BOOTS AND SHOES
which Invention has been communicated to ine from abroad by Michel Goetz of
Gratz Styria in the Empire of Austria Manager of a Shoe factory to be as
follows:-
This Invention relates to an improved burnishing machine for use in the
manufacture of boots and shoes and it consists in an arrangement or combination
of mechanism hereinafter described whereby the burnisher is caused to move
horizontally that is to say perpendicularly to the under surface of the heel or in
the same direction as in buruishing by hand and the work is performed in a
superior and more efficient manner than by the machines heretofore constructed.
The mechanism of the improved machine is carried by a vertical support standing
up from a base or bedplate and provided with horizontal arms carrying the shoe
holder and the guides for the burnisher as hereinafter described.
The upper part of the support overhangs the arms and carries a socket retained
in position by screws. This socket is capable of oscillating and carries a vertical
rod attached to the burnisher. The burnisher is heated by a gas jet supplied with
gas through a passage formed in the rod. A lifting plate is pivoted to one of the
horizontal arms and a notch or slot of sufficient length for the passage of the rod is
formed in the plate and in the arm.
The buruisher is pressed against the heel to be burnished or polished with an
elastic pressure by the combined action of a weight and a spring acting on the
vertical rod. After the polishing is performed the workman presses down a treadle
which by means of suitable links and levers elevates the lifting plate and the
rod carrying the burnisher. The treadle is locked in this position by a catch.
When the burnisher is thus elevated the boot or shoe may easily be taken out of
the holder or placed therein.

page_text: One end of an eccentric rod which imparts the oscillating motion to the
burnisher is connected to the rod carrying the burnisher and the other end of
this rod is connected to the eccentric strap. The eccentric is mounted on a
rotating shaft in such a manner that a projecting piece on the eccentric engages
with a slot in a disc also mounted on the rotating shaft and in this slot is a screw
which passes through the above mentioned projecting piece. The eccentric is also
provided with a slot through which the rotating shaft passes so that by means of
the screw the stroke of the eccentric and consequently that of the burnisher may
be varied according to the height of the heel. Movement is transmitted to the
aforesaid shaft by means of pulleys on a countershaft. A horizontal arm under-
neath the burnisher is provided with a slot into which enters the pivot of the
shoe holder; the latter being provided with a lever for turning the holder in a
horizontal plane during the operation of burnishing.
The shoe is clamped or retained in position underneath the burnisher by means
of a spring or screw so arranged as to enable the shoe holder to be turned so
as to present the heel in a suitable manner to the action of the burnisher. For
this purpose the heel is turned to the right and left by a piece of metal which
engages with the shoe.
The burnisher is caused to follow automatically the
different positions of the heel during the movement of the latter, the pressure
being regulated by the treadle herein before referred to.
The mechanisin for burnishing the edges of soles consists of a burnisher of
suitable shape capable of being moved backwards and forward by levers receiving
their movement directly from an eccentric fixed on a shaft rotated by pulleys ou
the counter-shaft herein before referred to. This burnisher is preferably carried in
guides arranged on the opposite side of the support to that on which the burnisher
herein before described is arranged and has a yielding or elastic pressure imparted
to it in the same manner as the burnisher used for the heels. For burnishing the
waist or sole the shoe is placed in an oscillating holder provided with rollers
running in suitable grooves in arms or guides beneath the burnisher the holder
being moved forward or backward by a hand lever the upper end of which enters
between two projections on the frame of the holder. The fore or toe part of the
shoe rests on adjustable sliding supports; a saddle piece being attached to the
sliding support by a pivot. The saddle piece is adjusted according to the length
of the shoe and the sliding supports are kept in their proper position by lateral
screws. The heel part of the shoe is fixed on the shoe holder in such a manner
that the heel is directed upwards and can be moved upwards and downwards by
means of a toothed rack which is raised and lowered by a hand wheel. This rack
is capable of being adjusted horizontally in a slot in the holder and is firmly fixed
by a set screw.
This holder with all the other parts before mentioned is suspended on pivots or
centres and oscillates on a horizontal axis so that any part of the surface of the sole
and waist can be brought under the action of the burnisher.

I, JOHN HENRY JOHNSON, of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman, do hereby declare the nature of this Invention which has been
communicated to me from abroad by Michel Goetz of Gratz Styria in the Empire
of Austria, Manager of a Shoe Factory, 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 an improved burnishing machine for use in the manu-
facture of boots and shoes and it consists in an arrangement or combination of
mechanism hereinafter described whereby the burnisher is caused to act in a
similar manner to hand burnishers and the work is performed in a more superior
and more efficient manner than by the machines heretofore constructed. In these
last mentioned machines the heels are burnished by causing the burnisher to move
in a circle around the heel. This method has the inconvenience of being liable to
loosen the parts or patches composing the heel, and the polish obtained is not
perfect so that it becomes necessary to finish it by hand.
In this improved machine the burnisher is caused to reciprocate or move to and
fro in a direction perpendicular to the under surface of the heel that is to say in the
same direction as in burnishing by hand and certain improved arrangements are
employed for supporting the boot or shoe and burnishing or polishing the edges
and undersurfaces of the sole as hereinafter explained.
And in order that the said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer
to the several figures on the annexed sheet of drawings the same letters of
reference indicating corresponding parts in all the figures.
Figure 1 of the accompanying drawings is an elevation showing one side of a
machine constructed according to this Invention and showing the mechanism for
burnishing or polishing the heels and other parts of the soles of boots or shoes.
Figure 2 is an elevation of the machine seen from the opposite side and Figure 3
represents an end view of the machine.
Figure 4 shews in detail the construction of an excentric disc and mechanism for
regulating the stroke of the burnishing iron.
Figure 5 represents on a larger scale the arrangement for holding or supporting
the boot or shoe when burnishing or polishing the under surface of the sole.
The working parts of the improved machine are carried by a vertical support A
standing up from a base or bed plate A¹ and provided with horizontal arms A²
and A³.
These arms carry the shoe holder and the guides for the burnishing iron as
hereinafter described.
The upper part of the support A is curved so as to overhang the arms A³ A³ and
is formed with a conical or taper hole for the reception of a moveable bush or
socket B capable of being fixed at any desired part of a bar or tool holder B by
means of set screws.

page_text: The said bar or tool holder is guided or steadied by passing through a slot in the
arm A which may be cast in one with the support or pillar A and carries a lifting
plate or lever C jointed to the arm at a This lever serves to elevate the rod B
being operated by a lever I pivotted to the underside of the arm A² at band worked
by a connecting rod H and a pedal G. A catch J is provided which holds down the
pedal G and maintains the burnisher in an elevated position when required. A
strong spring F is arranged above the arm A² and acts in concert with a weight E
on the upper end of the bar B in producing the requisite downward pressure on
the burnishing iron. This pressure may be regulated by means of the pedal G.
The tool holder B carries a burnishing tool D to which a reciprocating or to and
fro movement is imparted by means of an adjustable excentric M carried on a
rotating shaft R and connected to the bar B by a rod K jointed to the said bar
at L The shaft R is driven from a shaft R2 by means of a belt and fast and loose
pulleys S.
The burnishing tool or iron D is beated by a gas jet g supplied with gas by a
passage carried down the interior of the bar B and suitably connected to a gas
pipe at f.
The stroke of the burnishing iron is regulated by shifting the excentric M on
the shaft so as to alter its stroke. Figure 4 shews a side elevation and a section
of an arrangement for accomplishing this object. A disc M¹ is keyed upon the
shaft R and is connected with the excentric M by means of a projection N formed
upon the side of the latter and cutering a slot or recess in the disc M¹ where it is
retained by a screw O provided with a milled head P so as to enable the stroke of
the excentric to be regulated by turning the screw O and altering the throw of the
excentric by causing it to slide upon the shaft R which passes through a slot Q
formed in the excentric for this purpose.
The burnishing tool does not partake of any other movement beyond those
imparted as herein before explained and in order to present the work to the tool
in the proper manner the boot or shoe is stretched or clamped upon a holder herein-
after described. This holder is shown in position in the machine in figures 1 and 2
and figure 1 is a plan of the holder. The arm A³ carries a vertical pivot V on
which turns a shoe holder V2 provided with appliances for clamping or fixing the
boots or shoes in position during the operation of burnishing the heel and
consisting of a sliding bolt X capable of turning in the holder, a support Y in
a line with the bolt and a loop Z connecting the bolt X with the piece Y. The
boot or shoe is placed in the holder with the toe downwards and the heel is
clamped between the parts X and Y. All the parts of the heel that require
burnishing can then be readily presented to the action of the burnishing tool D
by turning the holder V bodily on the vertical axis of the pivot V by means of
a lever V and toothed segments Vs (figure 1") and turning the boot or shoe in the
holder upon the horizontal axis of the clamping devices X and Y the bolt X being
provided with a suitable knob or handle to facilitate the manipulation.
burnishing tool being capable of moving in a vertical direction readily accom-
modates itself to the different positions of the heel. When the operation is
complete the burnisher is elevated by means of the treadle G being retained in
this position by the catch J and the boot or shoe can then be readily removed
from the holder V.
The
For polishing or burnishing the under surface of the heel and waist or the toe
part of the sole the boot or shoe is placed on a holder constructed as illustrated in
figure 5. This holder travels on rollers in grooves T. in the arm A³ being operated
by a bent lever 2 engaging with two projections on the base of the holder. The
boot or shoe to be operated upon is placed in a frame 3 swinging on a horizontal
axis on centres 11 and 12. The toe part rests on an adjustable support 6 sliding
in guides 4 and 5 and the heel part rests on a support 8 the under surface of the
heel and sole being upwards. The support 8 can be raised or lowered or adjusted
vertically by means of a pinion 9 engaging with rack teeth connected to the
support 8. This support is also adjustable horizontally by sliding in a slot in

page_text: the frame in which it can be fixed in any desired position by means of a set
screw 10.
In order to assist in enabling the entire under surface of the sole to be brought
under burnishing action of the tool D in a suitable manner the frame 3 can be
turned upon the centres 11 and 12 by means of a lever handle 13.
For polishing or burnishing the edges a step shaped tool is employed. The bar
or tool holder B can be so arranged as to enable this tool to be substituted for the
burnisher D employed for the other parts of the sole or the edges may be burnished
by employing an independent mechanism to operate the edge burnisher as in the
arrangement illustrated in the drawing. As illustrated in figures 1. 2 and 3 the
apparatus is provided with a step shaped burnishing tool d attached to a holder c
to which a to and fro or reciprocating motion is imparted by means of a pulley S¹
on a shaft R¹ receiving motion from the shaft R and provided with a crank e
connected to the tool holder c by a link C jointed to the holder at C3 figure 2.
The tool holder C is connected to a bar C¹ capable of moving vertically in a guide
attached to or cast on the support A and the requisite elastic pressure is obtained
by means of a weight e¹ and a spring f¹ acting on the said bar.
Having now described and particularly ascertained the nature of the said
