Year: 1862

page_text: LETTERS PATENT to Thomas Cabourg, of 333, Rue St. Martin, Paris,
Empire of France, Boot and Shoe Manufacturer, for the Invention of
"IMPROVEMENTS IN MACHINES FOR THE PURPOSE OF UNITING TOGETHER BY
MEANS OF SCREWS LEATHER USED IN THE MANUFACTURE OF BOOTS AND SHOES
AND OTHER ARTICLES COMPOSED OF TWO OR MORE PIECES OF LEATHER."
Sealed the 8th July 1862, and dated the 6th May 1862.
PROVISIONAL SPECIFICATION left by the said Thomas Cabourg at the
Office of the Commissioners of Patents, with his Petition, on the 6th
May 1862.
I, THOMAS CABOURG, of 333, Rue St. Martin, Paris, Empire of France,
Boot and Shoe Manufacturer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINES FOR THE PURPOSE OF UNITING TOGETHER
BY MEANS OF SCREWS LEATHER USED IN THE MANUFACTURE OF BOOTS AND SHOES AND
OTHER ARTICLES COMPOSED OF TWO OR MORE PIECES OF LEATHER," to be as follows,
that is to say:-
The object of my Invention consists in the construction of a machine which
will form a thread upon a continuous length of brass wire, and at the same
time cause it to penetrate by screwing into any portion of leather, or such like
material, so as to unite them in one. For instance, if it be applied to unite
the upper leather or vamp of a boot or shoe with the sole or soles, it is only
requisite to present the materials to be united to the tapped end of the wire,
and the rotation caused by the machine will enable it to penetrate without the
necessity of having holes made into the leather to be joined; when sufficient
length is introduced, it is by means of mechanism cut close to the edge of the
material.

page_text: The machine by which this is effected consists of a pulley with a large
groove, upon which the wire to be tapped is wound. The wire when uncoiled
from the pulley passes through a hollow axle, which gives it a motion of rotation
in a plane perpendicular to the direction of its course when unwound from
the pulley; hence it has imparted to it a progressive spiral motion, and in
this way enters the tapping plate, and has the thread cut upon it; from the
plate it passes through a guide, and then enters into the leather or materials
to be united, and after penetrating them to a sufficient depth, it is cut by a
pair of knives, which by means of the motion of the wire and the disposition
of the knives give it an oblique cut, so as to form a sharp point upon the
succeeding part of the wire, which enables it to enter more easily the material
when in its turn it is brought into position. The knives are brought into
action by means of a series of levers and treadle, or by any other well known
means.
The machine is placed upon a frame, and may be worked by hand or other
motive power.
In using my machine, it is only requisite to apply lightly the leather or other
material to be united to the end of the tapped wire, it not being necessary to
first niere

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Cabourg in the Great Seal Patent Office on the 9th
July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
CABOURG, of 333, Rue St. Martin, Paris, Empire of France, Boot and Shoe
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of May, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me the said
Thomas Cabourg, Her special licence that I, the said Thomas Cabourg, my
executors, administrators, and assigns, or such others as I, the said Thomas
Cabourg, 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 "IMPROVEMENTS IN
MACHINES FOR THE PURPOSE OF UNITING TOGETHER BY MEANS OF SCREWS LEATHER

page_text: USED IN THE MANUFACTURE OF BOOTS & SHOES AND OTHER ARTICLES COMPOSED OF
TWO OR MORE PIECES OF LEATHER," upon the condition (amongst others) that I,
the said Thomas Cabourg, 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 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 Thomas Cabourg, do hereby declare the
nature of my 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:-
The object of my Invention consists in the construction of a machine
which will form a thread upon a continuous length of brass wire, and at the
same time cause it to penetrate by screwing in any portion of leather or such
like material, so as to unite them in one. For instance, if it be applied to unite
the upper leather or vamp of a boot or shoe with the solo or soles, it is only
requisite to present the materials to be united to the tapped end of the wire,
and the rotation caused by the machine will enable it to penetrate without the
necessity of having any hole to be made into the leather to be joined. When
sufficient length is introduced, it is by means of mechanism cut close to the
edge of the material. The machine by which this is effected consists of a
pulley, with a large groove, upon which the wire to be tapped is wound.
This wire when uncoiled from the pulley passes through a hollow axle, which
gives it a motion of rotation in a plane perpendicular to the direction of its
course when unwound from the pulley. Hence it has imparted to it a
progressive spiral motion, and in this way enters the tapping plate, and has
the thread cut upon it. From this plate it passes through a guide, and then
enters into the leather or materials to be united, and after penetrating them
to a sufficient depth it is cut by a pair of knives, which by means of the
motion of the wire, and the disposition of the knives, give it an oblique cut,
so as to form a sharp point upon the succeeding part of the wire, which enables
it to enter more easily the material when in its turn it is brought into
position. The knives are brought into action by means of a series of lovers
and treadle, or by any other well known means. The machine is placed upon
a frame, and may be worked by hand or other motive power.
In using my
machine it is only requisite to apply lightly the leather or other material to
be united to the end of the tapped wire, it not being necessary to first pierce
a hole as is generally done.

page_text: In order more clearly to illustrate my Invention, and how the same is
carried out, I have to this Specification appended the accompanying Drawings,
which are only intended to show the main principles of my Invention, it being
understood that modification may be adopted of all or any parts to suit
neculiar circumstances.
Figure 1 represents an end view of my machine;
66
2, being a side elevation, and
"
3, a plan. The same letters refer to the same or similar parts in
the different Figures.
My machine is composed of a pulley A, on which the wire to be tapped is
wound, which is indicated by the red line in Fig. 2. The axle A of this
pulley is supported in bearings in the rectangular frame B, which is supported
at one end by the upright C, and at the other by the hollow axle D, which
turns in the upright E, which is itself fixed on a stand firmly bolted to the
main foundation plate. All the mechanism connected with the knives is
fixed to the plate G, which mechanism is composed of a lever K, one
extremity of which is terminated in a hook, which is connected with the
rod P, the end of which is connected with the treadle Q; the other ex-
tremity of the lever K is formed with a sort of hook or fork, which
embraces a stud a, fixed in the vertical shaft L, which slides in the
guides M, N. On this shaft are two lugs or cars b, b, to which are attached
the extremities of the rods T, T; the other ends of these rods are connected
with the curved levers U, whose upper extremities are terminated in a
fork E, for the purpose of actuating the studs i, i, which are fixed in the
shanks of the knives f. f. The whole of the series of levers are fixed to the
plate G, which is firmly bolted to the two pieces g, g, which are cast with
the support E. The wire on leaving the pulley A traverses the length of the
hollow axle D, and at its exit has the thread cut upon it by the tapping
plate i, which is regulated by the screw d. After the tapped wire has left
the plate i, it passes through a guide e, and between the two edges of the
knives f, f, then, when wished, by acting on the end of the lever K with the
foot by means of the treadle Q the knives are actuated simultaneously, and
the edges having the form of an inverted V, they perform a double cut, one to
the right against the left to cut off the tapped wire, and the other oblique
for the purpose of making a point to the extremity of the wire. These
knives have their shanks formed square in section within the guides L', L.
to prevent them from turning round when acted on by the levers U, U; the

page_text: distance or movement of the knives is regulated by means of the screw N
fixed to the plate G. The levers are coupled so as to act simultaneously by
the rods T, T, connected with the vertical shaft L. The machine is put in
motion by means of the handle Q fixed on the axle of the toothed wheel R,
which gears into the pinion S, which gives motion to the hollow axle D, and
consequently the frame B and the pulley A, on which is wound the wire.
During this rotation the wire passing through the tapping plate i has a thread
cut upon it, then, when it has penetrated a sufficient depth into the leather or
other material to be united it is cut, as it has been previously shewn, by the
application of force to the treadle Q. The pressure is communicated to the
rod P, to the lever K, and consequently to the rods T, T, which acting on
the curved arms U, U, which communicate the motion to the knives, the
knives are brought back to their normal condition by means of the spring V
fixed on the frame of the machine. The action of these levers will bo fully
seen, reference being had to Figure 1 of the Drawings. This machine can
be constructed of any size and actuated by steam, manual, or any convenient
power.
Having now described my Invention, and how the same is carried into
effect, I wish it understood that what I claim and wish secured to me by the
before in part recited Letters Patent is,-
First, the general form and construction of my machine, substantially as
described in this Specification and illustrated in tho Drawings.
Second, the construction and use of the pulley A, on which is wound the
wire to be tapped, substantially as described in this Specification and illustrated
in the Drawings.
Third, the construction and use of the tapping plate, substantially as
described in this Specification and illustrated in the Drawings.
Fourth, the construction, disposition, and simultaneous action of the knives,
substantially as described in this Specification and more fully shewn in the
Drawings.
In witness whereof, I, the said Thomas Cabourg, have hereunto set my
hand and seal, this Fourth day of July, in the year of our Lord One
thousand eight hundred and sixty-two.
