I, JOHN OTIS COLLINS, a citizen of the United States of America, and a
resident of Marblehead, in the County of Essex and State of Massachusetts, do
hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved heel burnishing machine; and it has
for its object to quickly and efficiently burnish boot or shoe heels by power in a
manner similar to the usual hand work; and it is carried out as will be understood
from the following Specification, reference being had to the accompanying drawings,
wherein
Figure 1, represents a front elevation of the improved heel burnishing machine.
Figure 2, represents a side elevation of the same partly shown in section.
Figure 3, represents a vertical section on the line 3-3 shown in Figure 2.
Figure 4, represents a top plan view of the head of the machine; and
Figure 5, represents a cross section on the line 5-5 shown in Figure 3.
Similar letters refer to similar parts wherever they occur on the different parts of
the drawings.
A, represents the post or standard of the machine in the lower portion of which
is preferably journaled a driving shaft b, to which is attached a belt pulley B,
which is set in rotary motion by belt power applied to the pulley B' fast on the
shalt b. B is a loose pulley on the shaft b, onto which the driving belt is shipped
in stopping the machine as is usual in machines of this kind. C, is the head of
the machine, in a bearing in which is journaled a shaft D, the rear end of which
is preferably journaled and supported in a bracket A' secured to or forming a part
of the standard A, as shown in Figure 2. To the shaft D, is secured a pulley d,
to which a quick rotary motion is imparted by means of a belt E, leading from the
pulley B, as shown in Figures 1, 2 and 3. The shaft D, has a crank eccentric or
cam D' to which are loosely connected a pair of eccentric rods or links D" Du
pivoted in their outer ends to the levers D³ D³ which are secured to the respective
rock shafts,f, located and journaled in sliding bearing blocks F, F, which are
adjustable to and from each other in guides C C in the head C, as shown in the
drawings. CC" are regulating screws by means of which the positions of the
blocks F, F, are adjusted and by means of which said blocks are secured in position
after being adjusted as fully shown in the drawings. G, G, are the disc burnishers
secured to the respective rock shafts ff. It will be seen that by the mechanism
hereinabove described a quick rocking or oscillatory motion is imparted to the said
burnishing discs from the shaft D. Each of the burnishing discs has on its
periphery a corrugated or undulatory segmental portion g, g, against which the
boot or shoe heel is held as shown by dotted lines H in Figure 1 by the operator
during the burnishing operation. Each of the burnishing discs is heated by means

page_text: of a gas jet from a pipe I, or other equivalent heating device as is common in beel
burnishing machines. Each burnishing disc G, is adjustably secured to its shaft f,
by means of a set screw, shown in Figure 2, so as to enable the operator to adjust
such disc and its corrugated portion on said shaft to suit the requirements of the
work. For smaller heels the discs G, G, are brought nearer together by means of
the regulating screws C"C" and for larger heels said discs are moved corre-
spondingly farther apart and their bearing blocks secured in such adjusted positions
to suit the operator. The wax is applied to the heated burnishing discs in the usual
manuer. During the burnishing operation the discs G, G, are set in a quick
reciprocating or rocking motion as described, heated and the wax applied to them
as stated. The operator takes hold of the boot or shoe and guides the curved heel
surface thereon with proper pressure against the corrugated segmental portions g,g,
and rocks the heel as well as moves it forward and back so as to cause the
burnishing discs to come in contact with and properly burnish every part of the
curved portion of the heel.
By this arrangement all the advantage of the old hand burnishing process is
obtained in a very superior, rapid and highly finished manner.
For convenience in burnishing the top lift without danger of turning over its
edge, I have provided the following device. To the head C is secured a rest L
held adjacent to one of the oscillating discs G. On the disc G adjacent to the
rest L is a segmental flange M rigidly secured to the disc G and projecting beyond
its periphery. The rest L projects in front of flange M (as shown in Figures 1 and 4)
and its arrangement is such that the side of the heel may be laid against the rest Ĺ
and the face of the top lift brought against the flange M, and the side of the top
lift brought in contact with the disc G and burnished by the action thereof, the heel
being turned by the operator until the entire edge of the top lift has been acted
проп.
The function of the flange M is to determine the lateral position on the periphery
of disc G of the top lift, in other words it acts merely as a guide: and the function
of the rest L is merely to steady the shoe while the top lift is being burnished.
After the top lift is burnished the rest of heel is burnished down to the top lift
between discs G, G.
It is evident that the device above described for burnishing the top lift is not
essential to the operation of the machine as with care on the part of the operator
the whole heel may be burnished between the discs.
Dated this 4th day of May 1894.

A New or Improved Heel Burnishing Machine.
1, JOHN OTIS COLLINS, a citizen of the United States of America, and resident
of Marblehead, in the County of Essex, and State of Massachusetts, 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 a new or improved heel burnishing machine; and it has
for its object to quickly and efficiently burnish boot or shoe heels by power in a
manner similar to the usual hand work; and it is carried out as will be understood
from the following Specification, reference being had to the drawings left with the
Provisional Specification, wherein
Figure 1 represents a front elevation of the improved heel burnishing machine,

Similar letters of reference refer to similar parts wherever they occur on the
different parts of the drawings.
A, represents the post or standard of the machine in the lower portion of which
is preferably journaled a driving shaft b, to which is attached a belt pulley B,
which is set in rotary motion by belt power applied to the pulley B₁ fast on the
shaft b. B is a loose pulley on the shaft b, on to which the driving belt is

eccentric or cam D' to which are loosely connected a pair of eccentric rods or
links D D pivoted in their outer ends to the levers D³ D³ which are secured to
the respective rock shafts f, f, located and journaled in sliding bearing blocks F, F,
which are adjustable to and from each other in guides C¹ C¹ in the head C, as

discs has on its periphery a corrugated or undulatory segmental portion g, g, against
which the boot or shoe lieel is held as shown by dotted lines H in Figure 1 by the
operator during the burnishing operation. Each of the burnishing discs is heated
by means of a gas jet from a pipe I, or other equivalent heating device as is
common in heel burnishing machines. Each burnishing disc G, is adjustably

enable the operator to adjust such disc and its corrugated portion on said shaft to
suit the requirements of the work. For smaller heels the discs G, G, are brought
nearer together by means of the regulating screws C"C" and for larger heels said
discs are moved correspondingly farther apart and their bearing blocks secured in
such adjusted positions to suit the operator. The wax is applied to the heated
burnishing discs in the usual manner. During the burnishing operation the
discs G, G, are set in a quick reciprocating or rocking motion as described, heated

and back so as to cause the burnishing discs to come in contact with and properly
burnish every part of the curved portion of the heel.
By this arrangement all the advantage of the old hand burnishing process is
obtained in a very superior, rapid and highly finished manner.
For convenience in burnishing the top lift without danger of turning over its
edge, I bave provided the following device. To the head C is secured a rest L
held adjacent to one of the oscillating discs G. On the disc G adjacent to the
rest L is a segmental flange M rigidly secured to the disc G and projecting beyond
its periphery. The rest L projects in front of flange M (as shown in Figures 1
and 4) and its arrangement is such that the side of the heel may be laid against the
rest L and the face of the top lift brought against the flange M, and the side of
the top lift brought in contact with the disc G and burnished by the action thereof,
the heel being turned by the operator until the entire edge of the top lift has been
acted upon.
The function of the flange M is to determine the lateral position on the periphery

page_text: of disc G of the top lift, in other words it acts merely as a guide; and the
function of the rest L is merely to steady the shoe while the top lift is being
burnished. After the top lift is burnished the rest of heel is burnished down to
the top lift between discs G, G.
It is evident that the device above described for burnishing the top lift is not
essential to the operation of the machine as with care on the part of the operator
the whole heel may be burnished between the discs.
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 burnishing machine, the combination with a supporting frame, of boxes F
adjustable to and from each other rock-shafts journaled respectively in the boxes
and provided with burnishing discs, a rotary-shaft D having a cam or eccentric,
and connections between the cam or eccentric and the rock-shafts, substantially as
described.
2. In a burnishing machine, the combination with a frame of slidable boxes F,
devices for sliding the boxes to and from each other, rock-shafts journaled
respectively in the sliding boxes, a drive-shaft D having a cam or eccentric D',
links D engaged at one end with the cam or eccentric, and levers D³ secured to
the said rock-shafts and pivoted to the said links, whereby the rock-shafts are
simultaneously rocked by a single shaft, substantially as described.
3. In a burnishing machine, the combination with a standard having a head, of
a pair of movable boxes arranged upon the head, devices for adjusting the boxes
to and from each other, rock-shafts journaled respectively in the boxes and provided
with burnishing discs, a drive-shaft D having a cam D' and devices connecting the
cam with the rock-shafts for simultaneously rocking the latter by the action of a
single shaft, substantially as described.
4. In a burnishing machine, the combination with a standard having a head, of
sliding boxes F, independent screws C" engaging said head for adjusting the boxes
to and from each other, rock-shafts journaled respectively in the boxes, a shaft D
having a cam D', links D" engaged at one end with the cam, and levers D³
secured to the said rock-shafts and pivotally connected with said links for
simultaneously rocking the rock-shafts by the action of a single shaft, substantially
as described.
5. In combination with a rocking burnishing disc having a partial corrugated
and non-corrugated surface, a top lift guard M, secured to the non-corrugated
part of the disc, and a stationary top lift rest L, substantially as and for the
purpose set forth.
