COMPLETE SPECIFICATION left by the said Henri Adrien Bonneville at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 28th August 1865, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 24, Rue du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent; send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF PRESSES FOR THE COMPRESSION OF ELASTIC SUBSTANCES," com-
municated. to me by Joseph Wohl, a person residing at Strasbourg, in the
Empire of France aforesaid, and bave petitioned Iler Majesty. to grant
unto me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made solemn declaration that it is a
communication..

page_text: 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 figures of the
accompanying Drawing, and to the letters marked thereon, that is to say :-
This Invention relates to an improved construction of press, whereby cotton,
wool, bay, and other similar materials may be compressed rapidly and with
great facility.

I have avoided one of the inconveniences met with in the use of presses with
toothed wheels, viz., the breaking of the teeth when the pressure increases, by 1
making these wheels and the rack (which are usually of cast iron) of wrought
iron cemented or chilled, and by this means, and by the use of very fine
1oothing, I have obtained sufficient strength combined with great speed of
compression.
This press also offers: the advantage of being made either portable or fixed,
and is very easily manoeuvred; particularly on account of the system of .ties
adapted to the pressing, case for maintaining or opening and closing it during
the operations.
The accompanying Drawings represent the improved press.

like parts.

A is a framework which may be fixed in the earth or mounted on wheels
in order to render it portable. It is composed of five cross pieces and two side.
pieces. B, B, are uprights, bolted at their lower ends to the framing A ;
C, C, are cross pieces bolted to the upper ends of the uprights B, B, and
carrying the press; D, D, is a floor for the person who works the press; E is
the pressing box or chamber containing the materials to be compressed. It
is composed of four sides hinged to a bottom, which open like the petals of a
Hower, and turn down the sides against the uprights B, B, and the ends
against a railway H on which the box or case is fixed. The case is held
closed by means of four crotchets E¹, and may be opened and shut by
means of eight latchets with cramps E". It is completed by four walls or
inoveable lengthenings F, which serve for raising its walls when the materials
to be compressed are introduced., G, G, are ties placed inside and outside
the framework in order to strengthen it; I, cast-iron box or case enclosing
the mechanism for pressing. This case is bolted on the cross pieces, C by
means of the hooks J, J. K, angles serving for connecting the uprights B
with the framework A and the cross pieces C, and for supporting the flooring

page_text: D; M, small and rapid fly wheel for raising the rack and the pressing plate;
N, large fly wheel for pressing. The small fly wheel M having a speed ten
times greater than that of the fly wheel N, serves only for raising the rack
and the plate in order to accelerate the operation, to this effect the large fly
wheel is ungeared when the pressing is terminated. O is the pressing rack
secured to the pad or pressure plate P.
The apparatus being composed of two pressing cases the work may be
continuous, one of the cases being filled while materials are being pressed in
the other.
The dimensions of the different parts of this apparatus may be varied
according to the resistance opposed by the substances to be pressed.
Having thus described the nature of the said Invention, and the manner
in which the same is to be performed, what I claim is, the general disposition
and combination of the different parts of the said press, which may, however,
be modified without changing the principles which constitute the said Inven-
tion, particularly the application of cemented wrought iron to the manufacture
of the teeth of the rack and gearings, and the use of cramp latches for closing
the cases.
In witness whereof, I, the said Henri Adrien Bonneville, have here-
unto set my hand and seal, this Twenty-fourth day of August, in the
year of our Lord One thousand eight hundred and sixty-five.
