LIKE ARTICLES, a comununication from Félix Delacroix, a person resident
at 25, Rue St. Jacques, in Paris aforesaid, Engineer, upon the condition
(amongst others) that I, the said Henri Adrien Bonneville, my
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and scals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the

وو
NOW KNOW YE, that I, the said Henri Adrien Bonneville, 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:-
The Invention communicated to me relates to a new and improved
apparatus for doubling lengthwise stuffs, tissues, cloths, and all other
such like articles, by introducing them into a passage or canal more or
less inclined, in which the stuff or article is progressively caused to
advance, and is folded.
This apparatus is composed of a table upon which the stuff or article
is placed supported by a frame; of a metal plate placed above, the width
of which progressively decreases, and upon which the stuff or article is
gradually turned down and folded by the cover of the apparatus by
passing through an aperture in the length of the metal plate; this
apparatus being controled by regulators worked with screws or otherwise
according to the width of the stuff or article and the width of the
doubling. On issuing from the apparatus the stuff or article is caught
between a series of conveniently adapted drawing rollers actuated by any
sort of motive power.

apparatus; Fig. 2 is a plan of the same, the upper part being taken away;
Fig. 3 a section, by A, D, Fig. 2, of the same; Fig. 4 a front elevation,
seen from the end of the apparatus; Fig. 5 a plan of the table of the
apparatus cut in its centre; Fig. 6 is a section by C, D, Fig. 5; Figs. 7
and 8 are side and front views of elevations of the folding apparatus;
Fig. 9 is a regulator seen by itself; Fig. 10 shows a plan, a side, and an
end view of one of the racks; Figs. 11 and 12 show by side views
different ways of the cloth issuing from the apparatus; Figs. 13. and
13 are sections of the modifications that may be made in the table, and
in the other doubling picces; Fig. 14 shows a small wheel with little
points to guide the selvage of the materials. In all these Figures the
same letters of reference indicate corresponding parts.
K is the cast-iron table bearing horizontally upon a frame L, above,
to, and at some distance from said table is attached the plate O by bolts,
said plate has a bar along its upper surface which forms a ledge for
the side edge C, D, of the cover R to rest on, said cover is joined to the
table K by a bracket or flange which is attached to its upper surface
and to which it is fastened by hooks or hinged joints or otherwise;
said table K may be placed in a sloping condition. Between the table
K and the plate O there is a space where is placed a regulator
consisting of the rack e, e, e. Between the plate O and the cover R is a
similar regulator, and the piece of material intended to be doubled
passes by degrees through this same space, the edge of the side of the
plate O opposite to the part attached to the table K shown by a sloping
line g near to the stake or flange V, X. The doubling or folding of the
materials depends upon the form and construction of the plate O.
The screws and racks acting upon the regulators are independent of one
another. In front of the table K is another table S more or less sloping,
upon which rests the piece of material that is to be doubled, which in the
first instance passes in its single thickness between the table K and the
plate O. One of the selvages of the material is pressed against the lower
regulator e, e, e, and the other slides through the slot m, m; as it advances
this selvage is turned over by the cover R which causes it to fold over,
and said selvage arriving against the plate O is guided by the second
regulator e, e, e, and as the material is carried along the table K the
said selvage gets nearer and nearer towards the other selvage between
the table K and plate O, by which they are kept separate until the
material issues from between the table K. and the cover R, when it will

page_text: be found to be doubled in half, the two halves being in contact. The
cover is between the line V, X, and P, P, P. At the end A is the slot
by which the material comes out when folded or doubled. It turns
back and passes over the roller B, then under C, by means of a spiral
spring is pressed by the said roller C and parts with any uneveness
due to the nature of said material or to the slackness of the selvages,
then passes over the little roller D, which facilitates the drawing motion
of the cylinder F; springs conveniently arranged may also be used either
with the roller B or the roller D. When once the material is drawn
by the cylinder F it passes upon the reel G and is lowered into the
folder H according to the nature of the material; the rollers C and D
may be suppressed by placing over the roller B a presser roller; in the
same way the reel G and the folder H may be done away with by
drawing the material directly in line with the table.
In the space A, B,
another doubling apparatus may be placed with a regulator. The
folder H is balanced upon two axis a, a, at its upper end in two
bearings on the frame I; at the lower end of said folder is attached a
pin B to which is pinned one of the ends of the connecting rod C whose
other end is connected by a bolt to the iron arm d attached to the shaft
of the cylinder F operating as an eccentric and imparting an oscillating
motion to the folder, and so arranged that the bolt by which the
connecting rod is connected may be brought nearer to or more remote
from the centre of rotation, so that the said movement may be varied.
To be able to tell the length of the material doubled a counter can be
applied to the shaft of the cylinder F consisting, for instance, of an
endless screw, a cog wheel, and a hand shewing the number of turns.
the cylinder F makes. The reel G has bars on its circumference and
revolves in bearings on the frame I, being operated by a pulley e keyed
to its shaft, and which derives its motion from a strap passing over the
pulley keyed to the shaft of the cylinder F; near to this pulley are
the driving pulley g and the loose pulley g'. In order to render the
surface of the table more solid, upon which surface the folding or
doubling takes place, and in order to prevent the same from giving or
bending, two or three or more bars cross the same, and rest on the
bearings i, i, fixed to the edge of the said table and on the doubling
plate. The regulators are put in motion by two or more endless screws
and by racks 1, each of which racks having a hole in its either end
through which passes a rod m attached to the ends of the regulators;
said racks are provided with wormed projections n which screw into the

page_text: screw hole k, so that by turning the screw the racks, and consequently

the regulators, are moved forwards or backwards.
arrangement others may be used, such as screws, rods, or pinions
suitably adapted. The regulators may be advanced the whole width of
the apparatus and can be moved by hand if their two ends project, or if
the nature of the materials does not require them they need not be
employed at all. To prevent the material from rising above or getting
underneath the regulators when it is carried between the tables the said
regulators are crossed by their bars 0, 0, 0, 0, whose ends slide in grooves
cut in the table, the plate, and the cover in order that the materials may
be carried forward without hindrance. At the ends for guiding the selvage
little rollers with points may be used.
By means of the arrangement seen, Fig. 5, that is to say, the plate
being cut in its centre, the materials may be doubled equally well, that
is to say, that instead of being single they are by the form of the plate
and table already commenced to be doubled before entering between the
said table, and plate by cutting the cover according to the length and
the width of the table, the nature of the material, and the lines 6, 4, or
2, 2. In Fig. 2 the cover, instead of extending as far as the end A, A,
is cut at the point B; this point of cission varies proportionally to the
length and width of the table and the nature of the materials. The
rod C, shown by red lines, attached by a spring or screw to the end D,
modifies the point of cission at will; a similar rod may be placed at the
extremity of the plate O, this plate being properly supported the cover
may be hooked to hooks or otherwise; and to take away the material
it is rolled over rollers, and a slightly rounded, and triangular rod is
attached to the plate at the end of the cover at a sufficient distance to
allow room for the material to come out between the rod and the cover.
When the folded or doubled material comes out from the table, instead
of retaining it by rollers and cylinders it may be drawn out, as shown
in Figs. 11 and 12, and thus lessen the distance it has to go, as in A
and B.
Having thus described the said Invention, and the manner of putting
it into execution, I would have it understood that I do not confine
myself to the precise details above enumerated, as these may obviously
be modified without departing from the principle of the said Invention,
but what I claim and desire to secure by the said Letters Patent
is-

page_text: 1st. The doubling or folding of stuffs, tissues, or such like materials
by mechanical means and progressively by an inclined canal either
rectilineal, conical, triangular, or any other shape as described.
2ond. The table K mounted on the frame I combined with the
regulators e and the racks operating the regulating of the movement
of the material as described and set forth.
3rd. The cover R cut triangularly at the place where the material
leaves the apparatus, as described.
4th. The plate O mounted between the table K and the cover, R com-
bined with the regulators e and the racks operating as described and
set forth.
5th. The plate O combined with the table K and the cover R and
operating substantially as and for the purpose described and set forth.
6th. The grooves in the table K, the plate O, the cover R combined
with the bars o, as and for the purpose described and set forth.
In witness whereof, I, the said Henri Adrien Bonneville, have
hereto set my hand and seal, this Tenth day of August,
in the year of our Lord One thousand eight hundred and sixty-
nine.
