I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake and Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 a machine for burnishing boot and shoe heels, and it con-
sists in certain novel features of construction, arrangement and combination of parts,
which will be readily understood by reference to the description hereinafter given.

. Figure 13 is an axial section of the rotary heel seat burnishing tool.

page_text: Figure 14 is a similar section of the rotary heel rest.
In the drawings A is the column supported by the legs A¹, B is the driving shaft
carrying the pulleys C C and C: D is the frame of the head of the machine: E the
crank shaft for operating the reciprocating burnishing tool, and carrying the pulley F
and hand wheel G: H the vertically reciprocating tool carrier: J is the belt for
transmitting motion from the driving shaft B to the shaft E: K is a bracket bolted to
the side of the frame D and having mounted in bearings therein the shaft L carrying
at one end the pulley L' and at its other end a heel seat burnishing and beading
tool M, to which rotary motion is imparted by the belt N leading from the pulley L
to the pulley N¹ on the driving shaft B, and O is the jack rod, O¹ the jack lever, P the
jack supporting stand: Q the jack controlling spring and R the spring adjusting and
supporting bent rod, all constructed, arranged and operating to draw the jack with the
shoe thereon towards the burnishing tool.
In the operation of the machines heretofore in use in which the jack is pressed
towards the burnishing tool by a spring it has been found somewhat inconvenient to
hold the jack-rod away from the burnishing tool against the tension of its spring
while removing a shoe from the jack and placing another thereon.
To obviate this difficulty the hook O2 is clamped upon the jack rod O, and an arm 08
is firmly secured to the base of the column A, with the upper end of which arm the
hook O engages, when the jack is swung to the left and rear of Figure 1, as shown in
Figure 2, in which position the jack will be firmly held by the tension of the spring Q
so that the operator has both hands free for use in applying the shoe to, or removing
it from, the jack. This is a very great advantage. I have also found that the holes
in the tops of the heel portions of the lasts are not always bored at the same distance
from the rear end of the last, and also that the heels of boots and shoes do not always
bear the samo relation to the rear of the boot or shoe.
It is however very desirable that the boot or shoe should be so jacked that it shall
rotate about an axis corresponding, as nearly as possible, to the centre of the heel in
all cases.
In order to attain this very desirable end, there is secured to the inner end of the
jack lever O by means of the pivot screw a, the arm b provided with the longitudinal
dovetailed groove c, in which is fitted so as to be movable endwise therein the block d
which may be clamped in any desired position in said groove by the last supporting
pin S, the main body of which is made many sided and tapering, and provided with
the collar e to bear upon the face of the arm b upon each side of the groove c, and
with the screw shank to screw into a correspondingly threaded hole in the block or
nut d all as shown in Figures 6, 7 and 8.
By making the main body of the pin S polygonal in cross section and tapering, it
is adapted to fit holes of different sizes in the lasts, and the last is effectually prevented
from revolving about said pin but the last and shoe thereon together with the pin S
and the arm are made to revolve about the axis of the pivot screw a and it will there-
fore be readily seen that by so adjusting the block d and the pin S that the axis of the
pin S shall bear the same relation to the axis of the pivot screw a that the hole in the
last does to the centre of the heel, the vibrations of the jack due to rotating the shoe
heel while in contact with the burnishing tool will be reduced to a minimum.
In boot and shoe heels having concave edges the angle with which the vertical curve
meets the tread surface varies according to the degree of curvature given to the heel
edge in different heels, and the angle at which said curve meets the tread surface at
the sides of the heel is more acute than at the rear in the same heel, hence in order
to properly burnish a portion of the curved heel, viz. the top lift edge the top lift bead
or bevel and a portion of the tread surface of the heel, at one operation, the burnishing
tool must be so constructed as to fit approximately to said parts in each case: and to
obviate the necessity of having as many burnishing tools as there are styles of heels, and
render it practical to burnish the sides and rear of the heel without changing the
tools is the object of this invention.
To this end the main body of the burnishing tool is made with a working face
having a shape as viewed in plan in the form of a segment of an ellipse, or arc of a

page_text: circle, of a radius less than the radius of the smallest curve of a series of heels, and
the same is provided with a shank S' by which it may be secured in a suitable socket
in the reciprocating tool carrier.
The body T of the burnisher is provided with the shoulder i extending the whole
vertical length thereof for the purpose of burnishing the top lift bead or bevel, and
contiguous thereto, with the plane surface i¹ also extending the whole vertical length
of said tool, said plane surface serving as a guide or rest for the tread surface of the
heel, a portion of which it serves to burnish as the tool is reciprocated.
The remaining portion of the working face of the tool T is beaded or corrugated'
horizontally as shown in Figure 11.
To one side of the tool T is secured by the screws 9g the supplemental tool T¹,
the working face g₁ of which is curved as seen in cross section in the form of a
segment of an ellipse or circle of a radius less than the radius of the quickest
curve of the heel edge, and is beaded or corrugated horizontally as shown in
Figure 11.

of the tool T at the proper
This supplemental tool T may be adjusted relative to the tool T by slackening
the screws and setting up the set screw g³ or
working face thereof shall meet the plane surface
angle to fit the heel to be operated upon.
To the opposite side of the tool T is secured in like manner, by screws hh the
gauge plate T which is provided with the shoulder for burnishing the top lift.
bead or bevel, and with the set or adjusting screw ³ for adjusting said gauge to
the desired angle relative to the curved working face of the tool T.
By the employment of the parts T and T¹ constructed and arranged as shown
and described the burnishing tool may be adjusted to fit to the tread surfaces and
the curved top lift edges of heels having different curves, and thereby be adapted
to burnish the same, while the beaded portion of the part T is adapted to burnish
the remainder of the heel edge.
By the further addition of the gauge plate T2 the rear portion of the top lift.
may be burnished by presenting the heel to the burnishing tool as shown in dotted
lines at D¹ in Figure 9, and the sides of said top lift edge may be burnished by
presenting the heel to the tool as shown in dotted lines at E' in Figure 9.
The tread surface may be burnished by presenting the heel to the tool, as shown in
dotted lines in Figure 10 and traversing the heel horizontally at the same time that
the burnishing tool is being reciprocated vertically, and the convex portion of the
heel edge may be burnished in the same manner as the tread surface.
By the use of a burnishing tool constructed as herein described several different
patterns of hools having somewhat different curves may be burnished with the same
tool by simply adjusting the parts T and Ts relative to the part T, but in order to
cover the whole range of variation from a straight heel to the most concave heel
several forms of the parts T1 and T2 will be required to be used interchangeably.
M is a rotary tool for burnishing the heel seat, composed of the rand guard and
burnisher j firmly secured upon the shaft L so as to revolve therewith and the heel
seat bead forming tool mounted loosely upon the hub of the burnisher ; so as to
revolve only with the revolution of the heel in contact therewith.
✗ is a rotary wheel rest for supporting the heel when being acted upon by rotary
tool M said rest having a rounded peripheral edge, and mounted upon a stud in the
end of the arm N2 adjustably secured in the bracket K as shown.

spring for moving the free end of said jack-rod towards the burnishing tool: a hook
fixed upon said jack-rod, in combination with a fixed arm or stop to engage said
hook when said jack-rod is moved into a certain predetermined position, and hold
said jack in said position.

page_text: Second. In a jack for supporting a last with a boot or shoe thereon and arranged
to permit said last to be revolved to bring all parts of the heel edge, except the
breast into position to be acted upon by the burnishing tool: the combination with
the jack-rod, of a pivoted arm connected therewith and a pin to enter the hole in
the last adjustably secured in said pivoted arm, with its axis parallel to the pivotal
axis of said arm substantially as described.
Third. The combination with the jack-rod O, and the jack-lever 01, of the arm b
pivoted to said lever and provided with a dovetailed slot or groove extending
