HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18, Rue
de la Chaussée d'Antin, Paris, France, and 5, Piccadilly, in the County of
Middlesex, Patent Agent. "A NEW OR IMPROVED NAPPING MACHINE." A com-
munication from François Delamare and Pierre Désiré Chandelier, of Rouen,
France, Machinists.
The Invention relates to the manufacturing of plain or figured velveted stuffs at
a single operation by the regular or irregular motion of the carriage of the new
or improved napping machine, which may be provided with a number of working
cylinders, varying according to the more or less complicated nature of the kinds of
designs it is desired to produce.
This machine may be used for raising or napping all kinds of stuffs whatever
may be the nature of the textile fibres employed.
Great disadvantages have been hitherto occasioned in the difficulty of the work
by machines for the manufacturing of velvets by means of the napping of the stuffs,
and the increased sale of these kinds of stuffs has been hindered by the high cost-
price of the manufacture and by the wearing out of the brass or iron-wire wrapping
of the working cylinder, which requires very frequent sharpening on account of its
contact with the metallic casing which protects, the stuff at the spot where it is not
to be velveted, and, lastly, by the difficulty of manufacturing plain velveted stuffs
by a single operation.
By means of the new or improved machine plain or figured velveted stuffs may
be manufactured by a continuous working, thus giving an accelerated production
with the greatest facility.

page_text: The Invention is illustrated in the accompanying Drawings, in which Fig. 1 is a
side elevation of the machine; Fig. 2, a horizontal plan view of the same; Fig. 3,
a sectional side elevation of the same through the line X, Y, Fig. 2; and Fig.
and 5, modifications of the same.
The new or improved machine consists chiefly, 1st, of rods e, e', e¹¹, over and
under which passes the stuff which is held on a stretching roller E, covered with
fillet-card and holding the stuff by means of a cramping piece E¹ keyed on its
axis; 2nd, of a roller G covered with fillet-card that moves the stuff as the work
is done; 3rd, of two placing rollers B, B', which bring the stuff into contact with
the working cylinders A, A¹, both together or alternately, according to the kind of
stuff it is desired to manufacture; 4th, of a carriage C to which is imparted a
rectilineal reciprocating motion in the direction of the breadth of the stuff, inside
which is a frame D provided with flexible metallic blades d, d', separated from
each other in parallel rows with the stuff lengthways, and pressing on the stuff
when the rollers B, B¹, bring it into contact with the working cylinders A, A'.
The blades of the said frame are so arranged that the spaces between them which
allow the first working cylinder to act on the stuff, correspond in a direct line with
the metallic blades which hold the stuff brought by the placing roller under the
second working cylinder A', so that the parts of the stuff covered by the blades
under the action of the first working cylinder can be velveted under the action of
the second cylinder as they pass under the same; 5th, of the two working
cylinders A, A¹, covered with brass or iron-wire card, by means of which the
velveting is effected and to which a continuous rotating motion is imparted in the
direction in which the stuff moves. These two cylinders are held up by the carriage
of the machine by means of the brackets a, a¹, a¹¹, a¹¹, which are regulated by the
regulating screws c, c¹, c¹l, cl
The axes of the placing rollers B, B'; are held at each end by slides H, H³,
H", which move in brackets h, h, hu, h¹¹¹, fixed to the frame, and rest on
cams I, I, I, I, keyed on their shafts J, J', oscillating from left to right or from
right to left, in order to move the said rollers up or down so as to allow of or
prevent the contact of the stuff with the working cylinders A, A'.
The oscillating motion is imparted to the shafts of the cams by the eccentric M,
driven by the shaft N by means of the pinion n and wheel n¹. The roller m
revolving on the said eccentric acts upon the lever L, which through the medium
of the connecting-rod 7 sets in motion the balance K by which the oscillating motion
is transmitted through the handle-levers i, i, hinged on to the arins j, j¹, keyed on
the shafts of the cams J, J¹, The middle of the handle-levers i, i, is also hinged
on to the balance K and hooks on or off at will in order to allow the operator to
move the placing rollers down again as required.
The rectilineal reciprocating motion is imparted to the carriage C held by its
axle-journals, which slide into pedestals fixed on the tables of the frame, by the
plate which carries an eccentric roller revolving in the groove of the cross-
piece C, which connects the axle-journals of the carriage C. The plate p mounted
on the upright shaft P is set in motion by its wheel o' gearing with an endless
screw o mounted on the shaft N.
The new or improved machine is set in motion by its pullies R mounted on the
driving shaft O, carrying at its other end a pinion Q, by means of which the motion
is transmitted to the shaft N through the wheel q, pinion T, and series of
wheels t, t¹, t¹¹.
The roller G that moves the stuff is driven by the pinion. U mounted on the
driving shaft O, by means of which the motion is imparted to the wheel g of the
said roller through the wheels V, V₁, and the pinions v, v', so that the roller G
covered with fillet-card stretches the stuff, which is pressed upon the said roller G
by the pressure roller and slides over the rods, under and over which passes tho
said stuff which rotates the stretching roller E, the power of the cramping-piece
of which is so calculated as perfectly to stretch the stuff, which at the same time
revolves by its friction the cylinders B, B², and the stretchers F, F¹, which guide
4.

rotating motion is imparted by means of the large pulley S keyed on the driving
shaft O, the band or belt 8, and the two pulleys St, S", mounted on the axis of the
said working cylinders.
In Fig. 4, knives b, b¹ are substituted for the working cylinders B, B¹, in order
that the contact may be shorter in the work so as to obtain certain effects in small
designs.
In Fig. 5, the rectilineal reciprocating motion of the carriage C is differently
arranged. The connecting-piece C" is provided with a take about carrier, which
carries a roller " rotating in the oblique groove of a drum f¹ by the revolution of
which the reciprocating motion is operated without any dead points at each stroke
of the frame D. Motion is imparted to this drum by a belted cone o" on the
driving shaft O of the machine through another cone p¹¹ inside the machine, the
pinion g', the intermediate wheel r, and the wheel u mounted on the axis of the
drum, as shown in Fig. 4. The said cones consist of three pullies in order to change
the speed as may be required.
By means of the new or improved machine velvets of varied designs may be
manufactured by the reciprocating motion of the carriage by which the frame
provided with metallic blades is displaced at the same time as the working cylinders,
which slide together upon the stuff and produce therein velveted parts diagonally
from right to left and from left to right, which when combined with the parts
velveted by the second working cylinder produce designs in the shape of a lozenge
or any other figure, according as the reciprocating motion of the carriage is operated
by the varying motion of the eccentric of the desired shape for obtaining the
required design. Plain velveted stuffs may be also thereby manufactured at a
single operation by stopping the reciprocating motion of the carriage when the
spaces between the metallic blades are of the same width as the latter, and by
continuing the reciprocating motion when the metallic blades which hold the stuff
on the placing rollers are much narrower.
Having thus fully described the nature of the said Invention, and the manner of
carrying the same into effect, 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 Invention, and in particular the number
of the working cylinders may be varied according to the more or less complicated
nature of the kinds of designs it is desired to produce; but what I claim is, the
new or improved napping machine for the manufacture of plain or figured velveted
stuffs at a single operation by means of a carriage running regularly or not, sub-
stantially as above described and represented in the accompanying Drawings.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto set
my hand and seal, this Nineteenth day of April, in the year of our Lord
One thousand eight hundred and seventy nine.
