THE MANUFACTURE OF THE LEGS OF HALF BOOTS," a communication to me
from Louis Badaracco, a person resident at Passage du Saumon, Paris,
aforesaid, Merchant, and have petitioned Her Majesty to grant unto me,
my executors, administrators, and assigns, Her Royal Letters Patent for
the same, and made solemn declaration that it is a communication.
NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the Invention, and
the manner in which the same is to be performed, reference_being_had_
-to-the-accompanying Drawings, and to the figures and letters marked
thereon, that is to say :-
The Invention communicated to me relates to an apparatus destined
to unite, fix, and glue the edges of the spring sides of the leg and of the
upper of half boots in order to facilitate very materially the sewing of
the same.
Fig. 1 in the accompanying Drawings represents a plan of two
apparati, the one on the left hand being exposed open to receive the
pieces to be put together, and the one on the right hand shut to operate
the pressure and gluing of the same; Fig. 2 is a longitudinal section
taken by the line A, B, Fig. 1, of one of the frames of the apparatus
with its accessory parts; Fig. 3 is a plan, and Fig. 4 a side view of an
accessory implement for accomplishing one of the operations required,
as herein-after explained.
or corners.
This apparatus consists of two double frames of cast iron a united by
hinges b, and thus capable of folding over one on the other. In these
frames are placed polished iron plates C supported by projections & fixed
to or cast with the cast iron of the frames, and at its four inner angles
Each plate C is about the same length as the interior of the
frame, but its width is less than that of the said interior, so that by
means of an adjusting thumbscrew e traversing the side of the frame
the two plates in apposition may by sliding in the frame be brought
nearer to one another or separated further from one another according
to the width of the hinder part of the leg of the boot placed between the
two spring sides. For this purpose on the end of each plate c are rods f,
which pass through slots g in a flange attached to or cast with the cast
iron at right angles with the edge of the hinder part of the frame, and
the ends of these wormed rods are furnished with hand screw nuts h,

page_text: which ensure the maintenance of the plates C firmly attached to the
frames after being placed at the requisite distance from one another.
Each plate c has a grooved opening, in which is set a little plate i with
a small flange on its sides and round part, which flange adjusts itself in
the groove. This little plate is shaped exactly the same as the piece of
clastic which is destined to be attached to the leg of the half boot, only
it is not so large. Each little plate i has on its under surface and at its
centre an oblong ring j, which passes through a longitudinal slot in a
broad, strong, flat spring 7, whose ends rest on the under surface of the
large plate C. Near to each end of this spring is attached at its centre.
point a smaller flat spring m, whose two ends rest on the under surface
of the little plate i, and on the middle of said large spring's exterior face.
is attached a pin on which plays a swivel hook n. The curbed part of this,
swivel hook forms a cam, and if by pressing on its rod it is made to.
penetrate more or less through the ring attached to the little plate i this
latter is forced with more or less pressure into the grooved opening of
the large plate C. By withdrawing the hook from the ring the little
plate is repelled from the opening by means of the double action
exercised on it by the broad spring and the small ones m.
To operate the union of the parts of the half boot above indicated in
the space a' between the two frames a forming one of the sides of the
apparatus is inserted the leg of the half boot folded down and sewn.
beforehand to the upper of the boot, after which there is folded over the
two plates c the part with the necessary slides or slopes to receive the
clastic spring sides, whose edges are inserted under the flanges of the
little plates ; then by pressing on the rod of the swivel hooks n acting
on the ring the little plates i are forced into the openings of the
plates C, and the edges of the said slides or slopes are taken hold of and
firmly maintained between the flanges of the little plates i and the groove
in the large ones C. The outer edges of the upper surface of the slides
or slopes are then glued; on said edges are placed the spring sides,
which thus placed cover the little plates i; then the edge of the upper
surface of said spring sides is also glued, on which edge the cloth or
other material composing the lining of the half boot will afterwards be
placed to be glued thereto. This cloth previously prepared with slides
or slopes like the leg and corresponding with the spring sides is then
placed in the same way on the two other plates C constituting the other
side of the apparatus, but to compel the edges thereof to penetrate under

page_text: the flanges of the little plates i the implement represented, Figs. 3 & 4,
is employed in consequence of the little resistance of the cloth; said
implement or tool consists of a flexible blade of metal in the shape of a
fork, suitably formed to surround the edges of the little plates i under
their flanges. The two double frames a thus furnished are folded over
one on the other, and the work pressed between them to operate the
gluing by adherence by hooking on to a projection o under the lower
frames the hooks p jointed on to the upper ones.
The apparatus above described may be placed, as represented in Fig. 1,
on the ends of a moveable arm p' turning on a strong pin q_set_in_a_
foot_fixed-on-a-table.-For-this-purpose the lower double frame has a
strong short pins, which is placed and can turn in a socket t at the end
of each arm. This double apparatus accelerates the work by leaving
one side of a half boat to dry in one of the apparati whilst the remaining
side is being prepared in the other.
Having thus described the nature of the said Invention, and, the
manner of carrying the same into effect, I would have it understood I
do not confine myself to the precise details above enumerated, as these
may obviously be modified without departing from the principle of the
Invention; but what I claim and desire to secure by the said Letters
Patent is, an apparatus for the manufacture of the legs of half boots
constructed and operating as above described, and shewn in the accom-
panying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and seal, this Nineteenth day of February,
in the year of our Lord One thousand eight hundred and seventy.
