Lakc, & Co., Patent Agents, Southampton Buildings, London,
for the Invention of "AN IMPROVED MACHINE FOR TRIMMING OR BUR-

PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 28th October 1874.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "AN IMPROVED MACHINE FOR TRIMMING OR
BURNISHING THE EDGE OF BOOT AND SHOE SOLES AND HEELS," a communication,
to be as follows:
1
This Invention relates to a machine for trimming or burnishing the
edges of the soles and heels of boots and shoes, and consists mainly in a

page_text: separate rasping or burnishing sleeve, a clamping guide, and an arbor,
all being so constructed, arranged, and combined as to give the sole of
boots or shoes the required shape and polish.
It also consists in an adjustable gauge, which has an operative screw
and fork arranged and combined with the rasping and burnishing sleeve
and the other parts above mentioned.
It further consists in an adjustable gauge having recesses to receive
the teeth of the rasping and burnishing sleeve in order to prevent the
revolving of the said sleeve on and independently of the arbor so as to
revolve the clamp guide and loosen the screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 26th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of October, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Robert Lake, Her special
licence that I, the said William Robert Lake, my executors, adminis-
trators, and assigns, or such others as I, the said William Robert Lake,
my exccutors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVED MACHINE FOR TRIMMING OR BURNISHING THE EDGE OF BOOT AND SHOE
SOLES AND HEELS," a communication to me from abroad by Louis Cōté,
of St. Hyacinthe, Quebec, Canada, Manufacturer, upon the condition
(amongst others) that I, the said William Robert Lake, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the

page_text: nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said William Robert Lake, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification:-
The first part of this Invention relates to a separate rasping or
burnishing sleeve, a clamping guide, and an arbor, all being arranged,
constructed, and combined as herein-after described and as represented in
the Drawing.
The second part of the said Invention relates to an adjustable gauge,
its operative screw and fork being arranged and combined with the
rasping or burnishing sleeve, the guide, and the arbor, to operate as
specified.
The third part of the said Invention relates to providing the adjustable.
gauge with recesses to receive the teeth of the rasping or burnishing
sleeve to prevent the revolving of this sleeve on and independently of
the arbor, so as to revolve the clamp guide and loosen the screw.

page_text: The sleeve C is a short tube of steel, having either rasping or cutting|
teeth or burnishing projections upon its outer surface or periphery.
The clamping guide D, shown in end views in Figures 7 and 8, in side
view in Figure 10, and in longitudinal section in Figure 9, is inserted in
and fitted to the bore of the sleeve C without extending quite to the
adjacent end of the arbor. A clamp screw g arranged in the bore of the
guide D and screwed into the arbor serves to hold the guide, and by means
of it the sleeve to the arbor, so as to be revolved by it when it may be in
revolution. This method of making the sleeve .C and the clamping
guide D admits of the ready removal of either from the arbor for repair
or for the substitution of others as occasion may require. Furthermore,
there is upon the arbor and encompassing it another sleeve or adjustable
gauge E, it being a tube fitted to slide upon the arbor and the sleeve C
lengthwise thereof. A stud h extends from the gauge E into a short
groove i made in the arbor longitudinally, the same causing the gauge E
to revolve with the arbor. The gauge E is also grooved transversely to
receive a fork k pivoted to a screw / screwed into and through a pro-
jection m elevated on and making part of the frame. On revolving the
screw the gauge may be moved either nearer to or farther from the annular
lip n of the clamping guide, as the thickness of a sole to be trimmed or
burnished on its edge may require while the machine may be in
operation.
In order to releive the clamp screw from any tendency to be unscrewed
from the arbor by the rasping or burnishing sleeve while in revolution
and pressed against a sole, the gauge E is formed with recesses o arranged
with respect to its bore, as shewn in end view, Figure 11. The sleeve
teeth or burnishing projections extending into their recesses will cause
the sleeve to revolve with the gauge and the arbor. Thus it will be seen
that whichever way the arbor may be revolved there will be no tendency
of the sleeve to revolve the clamp guide so as to loosen the clamp screw.
The gauge, therefore, besides performing the function of a gauge, serves
another purpose as explained.
This machine has been found to be of great utility. By the arrange-
ment of the gauge E, the rasping or burnishing sleeve, and the guide
together, and so as to extend on the arbor beyond one end of the frame as
shewn, a workman can readily present to them a boot or shoe to be
trimmed or burnished on its sole edge, and while holding it can turn it

page_text: or move it as may be necessary to effect the proper reduction or burnishing
of its edge, the guide lip n being at the time inserted in the groove or
space between the sole and the upper.
Having thus fully described the said Invention, as communicated to
me by my foreign correspondent, and the manner of performing the
same, I wish it understood that I claim,—
First. The separate rasping or burnishing sleeve C and the clamping
guide D, constructed and arranged together and with and connected to
the arbor A, as herein specified.
Second. The adjustable gauge E and its operative screw 7 and fork k
arranged and combined with the rasping or burnishing sleeve C, the
clamping guide D, and the arbor A, as above described.
Third. The adjustable gauge E provided with the recesses o or
equivalent device in combination and arranged with the rasping or
burnishing sleeve C, the clamping guide D, arbor A, and clamp screw,
as above specified.
Fourth. A machine for trimming or burnishing the soles and heels of
boots and shoes, and which consists of the various parts or devices con-
structed and combined as shewn in the accompanying Drawing, and
operating to effect the purposes of this Invention in the peculiar manner
above described.
In witness whereof, I, the said William Robert Lake, have here-
unto set my hand and seal, this Twenty-sixth day of March, in
the year of our Lord One thousand eight hundred and seventy-
five.
Witness,
