HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS IN
SHOE HEEL AND EDGE BURNISHING MACHINERY." A communication from abroad
by Benjamin Franklin Larrabee, of Lynn, Massachusetts, United States of
America.
My Invention relates to improvements in heel and edge burnishing machines, of
which the following is a full, clear, and exact description, reference being had to the
accompanying Drawings, making a part thereof:-
In said Drawings,
Figure 1 represents a plan view of my Invention.

Fig. 2 represents a front elevation, and Fig. 3 represents a side elevation of
the same.
Fig. 4 represents a longitudinal section of the burnisher shaft, its bearings,
sleeve, and burnisher, etc.
Figs. 5 and 6 represent sectional views of the universal joint connecting the tool
carrier with the movable frame.

DESCRIPTION.
The shoe a is supported by a jack, one part of which is the spindle b, which
bears upon one end a heel last c, the spindle being mounted in a bearing d, as
shown, in order that it may have a. motion on its axis; the other part of the
jack is the disk e, the flat part of which bears against the tread of the heel, the
Dine all

page_text: disk being mounted by a ball f and socket g, or universal joint, in order that it
may move on its axis, and being pressed firmly against the heel of the shoe by the
lever h, and treadle strap i, and treadle k. The treadle k is held in place by the
ratchet l.
I prefer to use a spring m, as shown, to throw the lever h back, and also to use a
spring between the lever and its treadle, in order to make it certain that the
ratchet shall properly hold the treadle. This jack constitutes the first part of my
Invention.
The
The burnisher tool n is mounted upon the shaft o, which is journalled at the end
of the tool carrier A; and this shaft is oscillated by the crank p, connecting rod q,
and crank on the shaft 8, which is also journalled across the tool carrier A.
pulley on the shafts is connected with the driving pulley B₁ by a belt or cord,
and the frame B in which this pulley is journalled is connected to the tool carrier A
by a universal joint, in order that the tool carrier may be moved up and down from
side to side and on its axis.
It is desirable also that the tool carrier may be moved back and forth a short
distance; and in order to permit of this motion the frame B is mounted upon
wheels which rest upon the tracks t, t. The pulley B¹ derives its motion from the
shaft and pulley B¹¹
For greater nicety of adjustment the socket of the universal joint is made in
two parts u, u, which clamp the cross bar B of the frame B, in order that this
socket may be set at any point along the cross bar B1, as may be required for
different heights of heels.
The tool carrier A, in combination with its two shafts, one oscillating and the
other revolving, constitutes one part of my Invention; and the combination of this
tool carrier and its shaft with the pulley frame, by means of a universal joint,
constitutes a third part of my Invention.
Making the universal joint adjustable across the pulley frame constitutes a fourth
part of my Invention.
The tool n has a lip n¹ to enter between the upper and the heel, and a self-
adjusting guard n" to bear upon the tread of this heel; this guard is pressed in
one direction by the spring n¹, so that its distance from the lip n¹ varies with the
height of the heel to be burnished.
The combination of the burnisher with its lip and guard constitutes a fifth
part of my Invention.
The burnisher is provided with a shank n", which enters the shaft o, and said
shank is clamped in place by means of the block o' and set screw, the said set
screw having its nut in the sleeve o¹¹¹.
This manner of securing the tool to its shaft is also one part of my Invention.
The operation of my machine is as follows:-The shoe is placed upon the heel
last c, and the operator clamps it securely by pressing down the treadle k, and
catching it in the ratchet l. The operator then reaches forward and grasps with
one hand the handle A¹ of the tool carrier A, and brings the tool in proper
position on the heel. (If heels are to be burnished the clamp is placed under the
heel; but if edges are to be burnished the clamp is placed about midway between
the toe and heel of the shoe.) With the other hand the shoe is moved gradually
about the axis of the spindle b and disk e, so as to bring all of the edge to be
burnished in contact with the burnisher; at the same time the tool carrier is moved
gently forward and back, both hands moving together, and thus lessening the labor
of each, the operation very closely resembling that with the ordinary hand tool,
with the exception of the vigorous rubbing motion necessary with the hand tool,
the same effect being produced in my machine by reason of the two being moved
by power.
The machine is so speeded commonly as to give about 1500 revolutions per
minute to the burnisher shaft.
C is the frame or support, and D, D, is the belt shipper in the usual way.

page_text: What I claim as my Invention is,―
1st.
☑alination the spindle b, heel last c, disk e, lever h, treadle strap i, and
treadle k, substantially as described.
2nd. In combination the tool carrier A, tool n, shafts o, s, and connections p, q, r,
the shaft 8 revolving and the shaft o oscillating, all as set forth.
3rd. The combination of the tool carrier A with its two shafts o and 8, one
oscillating and the other revolving, with the pulley frame B by means of the
ball-and-socket joint, as set forth, in order that the tool carrier may have the
motions above mentioned without affecting the driving of the tool.
4th. In combination with the tool carrier A and frame B the adjustable clamps
u, u, and cross bar B111, as set forth.
5th. In combination the heel burnisher n, lip n', and self-adjusting guard n", as
set forth.
6th. In combination the tool n and its shank n¹, the hollow shaft o, sleeve o¹¹1,
set screw o¹¹, and block o¹, as set forth.
7th. In combination the jack, the tool carrier A, the pulley B', frame B, tracks t, t,
and pulley s', substantially as described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Second day of January, in the year of our Lord
1878.
