-
We, CHARLES CHEVALLIER, MARK ISIDORE OLIVIER, and EUGENE ROLLAND,
all of the City of Brussels, in the Kingdom of Belgium, do hereby declare the
nature of the said Invention for "A MACHINE FOR MAKING AND APPLYING, AS
SOLES TO SHOES AND BOOTS, GUTTA PERCHA, CAOUTCHOUC, AND OTHER ANALOGOUS
SUBSTANCES ADAPTED FOR THAT PURPOSE," to be as follows:-
This Invention relates to a machine composed of two principal parts,
namely, a mould and a cylinder or roller. The mould is formed of two parts
fitted to each other; into this mould is placed and fixed the last with the
upper" of the boot or shoe thereon to which the sole is to be applied. The
substance employed for the sole is first made soft or plastic, and then placed
on the surface of the last, and the mould in this state is passed under a curved.
pressure roller, which has the effect of spreading the substance of which the

page_text: sole is to be formed; during this time the mould is held and guided in proper
position by rollers between which the edges of the mould fit. The axis of
each of the aforesaid rollers has a spur wheel fixed thereon, and gearing two
and two into each other, said wheels being all of similar size, for transmitting
the same amount of motion from the prime mover to each roller; the pressure
of said rollers on the mould may be adjusted and regulated by screws or
otherwise. By these means the substance under pressure receives the necessary
form for the sole, and is at the same time firmly united to the "upper" of the
boot or shoe, so that when it has passed under the aforesaid pressure roller
the boot or shoe is finished with the exception of the heel, which can be
affixed thereto in the usual way.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Chevallier, Mark Isidore Olivier, and Eugene
Rolland in the Great Seal Patent Office on the 24th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
CHEVALLIER, MARK ISIDORE OLIVIER, and EUGENE ROLLAND, all of the City of
Brussels, in the Kingdom of Belgium, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Charles Chevallier, Mark Isidore Olivier, and Eugene Rolland, Her
special licence that we, the said Charles Chevallier, Mark Isidore Olivier, and
Eugene Rolland, our executors, administrators, and assigns, or such others as
we, the said Charles Chevallier, Mark Isidore Olivier, and Eugene Rolland,
our executors, 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 "A MACHINE FOR MAKING AND APPLYING, AS
SOLES TO SHOES AND BOOTS, GUTTA PERCHA, CAOUTCHOUC, AND OTHER ANALOGOUS
SUBSTANCES ADAPTED FOR THAT PURPOSE," upon the condition (amongst others)
that we, the said Charles Chevallier, Mark Isidore Olivier, and Eugene
Rolland, our executors or administrators, by an instrument in writing under
our or their hands and seals, or under the hand and seal of one of us or them,
should particularly describe and ascertain the nature of the said Invention,

page_text: 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 Charles Chevallier, on behalf of myself and
the said Mark Isidore Olivier and Eugene Rolland, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
Our Invention relates to a machine composed of two principal parts, namely,
a mould and a cylinder or roller; the mould is formed of two parts fitted to
each other; into this mould is placed and securely held the "last" with the
upper" of the boot or shoe thereon to which the sole is to be applied. The
substance employed for the sole is first made soft or plastic and then placed
on the surface of the last, and the mould in this state is passed under a curved
pressure roller, which has the effect of spreading the substance of which the
sole is to be formed. During this operation the mould is held and guided in
proper position by rollers between which the edges of the mould fit. The
axis of each of the aforesaid rollers has a spur wheel fixed thereon, and
gearing two and two into each other, said wheels being all of similar size, for
transmitting the same amount of motion from the prime mover to each roller;
the pressure of the said rollers on the mould may be adjusted and regulated
by screws or otherwise. By these means the substance under pressure
receives the necessary form for the sole, and is at the same time firmly united
to the "upper" of the boot or shoe, so that when it has passed under the
aforesaid curved pressure roller the boot or shoe is finished with the exception
of the heel, which can be affixed thereto in the usual way.
In order to explain our said Invention as completely as possible, we now
proceed to describe the best means we are acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheet of
Drawings hereunto annexed, and to the numeral figures and letters of reference
marked thereon respectively, as follows:--
DESCRIPTION OF THE DRAWING.
Figure 1 represents a top plan view of the mould; Figure 2, a plan view
of the bottom or under side of said mould; Figure 3 is an elevation of the
inside of one half of the mould; Figure 4 is an elevation of the outside of said
mould; Figure 5 is a transverse and vertical section of the mould with a
"last" therein, and as they would appear when in the act of being passed
under the curved pressure roller hereafter described and referred to; this

page_text: Figure also exhibits the general arrangement and disposition of the mechanism
employed for advancing the mould under the aforesaid curved pressure roller;
Figure 6 represents a side elevation of the mechanism; Figure 7, detached
parts herein-after referred to.
At each of the foregoing Figures we employ similar letters of reference to
denote corresponding parts, in so far as such parts appear or can be seen
at each of such said Figures respectively.
The mould is formed of metal in two parts, as exhibited, to admit of the
"last" with the "upper" thereon being placed therein, after which the two
halves of the mould are forcibly pressed together and held in that position by
the screws A, A. Upon referring to Figure 3 of the Drawings, the lines B, C,
of the mould shew the thickness of the sole of the boot or shoe when finished.
The lines B, D, shew the height of the chops or jaws of the mould, which
embraces the "last" and " upper," and the lines *, *, at Figures 1 and 2,
shew the points of junction of the two halves of the mould. It will be seen
upon referring to Figure 4 that the outer edge of each half of the mould is
formed of the same curvature as that which it is desired to have the sole
of the boot or shoe.
We now proceed to describe the mechanism which we employ for giving
the desired form and pressure to the sole of the boot or shoe, and for advancing
the said sole under the curved pressure roller F, as follows:-At Figures
5 and 6, L is a shaft, on which is securely fixed the curved metal roller F and
spur wheels M, M, said shaft being supported by bearings in a suitable
framing, as at 8, Figure 6, and rotatory motion imparted thereto in any
convenient manner. There are other rollers and wheels K and M placed and
adjusted by convenient means immediately under the before-mentioned wheels
and roller F. The wheels M gear into each other and thus receive an equal
amount of motion, and the rollers K, which are fixed on the same axes or
shafts as the wheels M, are of such diameters as to admit of the edges G
of the before mentioned compound mould being introduced between the
rollers F and K, K, and advanced thereby by reason of the edges of the
mould being forcibly pressed between said rollers by means of endless bands
passing around the pullies P or other suitable means. The operations of the
above mechanism are as follows:-Suppose the mould containing the "last"
with an "upper" thereon and the substance of which the sole is to be formed
to be placed between the rollers K, K, and motion imparted to said rollers,
the effect will be to advance said mould under the roller E, which by its
pressure upon the plastic material will impart thereto the desired form for the
sole of the boot or shoe, and at the same time unite it firmly to the exposed

page_text: portions of the "upper" of said boot or shoe. Any excess of material becomes
squeezed over the edges C, C, on to the parts C, E, of the mould. We would
here observe that as the operation of "lasting" the "uppers" of boots and
shoes forms no part of this Invention, we deem it unnecessary to enter into
any explanation thereof, such operation being well known and commonly
practised; and we desire it to be distinctly understood that our Invention
consists solely in the means which we employ for attaching soles to the
uppers" of boots and shoes, as above stated.
Having now fully described and set forth the nature and object of our said
Invention, together with the best means we are acquainted with for carrying
the same into practical effect, we hereby declare our Invention to consist in,
and we claim, a machine of the construction above particularly described, set
forth, and represented, for the purpose of making and applying as soles to
shoes and boots gutta percha, caoutchouc, and other analogous substances
adapted for that purpose.
In witness whereof, I, the said Charles Chevallier, have hereunto set
my hand and seal, this Thirteenth day of September, in the year
of our Lord One thousand eight hundred and fifty-eight.
Witness,
A. CROVY.
