PROVISIONAL SPECIFICATION left by the said Henri Adrien Bonneville at
the Office of the Commissioners of Patents on the 14th December 1877.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18,
Rue de la Chausséo d'Antin, Paris, Franco, and 6, Piccadilly, in the County of
Middlesex, Patent Agent. "A NEW OR IMPROVED NAPPING MACHINE" A com-
munication from abroad by François Delamare and Pierre Désiré Chandelier,
Machinists, two persons resident at Rouen, France.
This Invention relates to a new or improved napping machine arranged in such a
manner that all stuffs in general may be napped thereby, of whatever material and
however light, with a regular dressing without leaving any rays, a result which
it has been hitherto impossible to attain with machines of the systems already
known.
In treating light stuffs the points of the brass or iron fillet cards forming the
lining of the reciprocating rollers, and penetrating into the cloth or stuff, are only
engaged according to the degree of thickness of the stuff submitted to the operation,
and are afterwards disengaged by the reciprocating rotary motion imparted to the
rollers.
The new or improved machine consists principally,-
1 Of rollers which keep the cloth stretched under the action of the operation

page_text: 2. Of rollers placed two-by-two on each side of the middle of the machine holding
up the stuff during the operation of napping, and which are so arranged as to be
brought into contact with or separated from the operating rollers, as need be.
3. Of a variable number, according to the width of the stuff, of rollers lined with
brass or iron fillet card placed at equal distances on each side of the machine, and
arranged across the stuff so as to operate in the empty space between the rollers
which hold the stuff, each roller consisting of two parts, so that the look of the point
of the one is in a reverse position to that of the other, in order that by means of the
reciprocating motion the stuff may be worked as much one way as the other The
points of the cards of the end rollers are always in the same direction, so that in 1
rotating they stretch the stuff in width and prevent it from being displaced.
4. Lastly. Of stretching rollers which change the position of the stuff as the work
is done.
The different parts of the machine are as follows:-A roller that crosses the stuff
holds it on another stretching roller lined with fillet cards. This roller carries on its
axis a brake pulley acted on by a metal blade connected at a fixed point to the
frane of the machine, having at its other end a rod, from which is suspended a
weight which causes the metal blade to exercise a friction on the break pulley,
which gives the tension to the stuff by incans of the stretching 1oller.
The stuff is kept in contact with the series of operating rollers by means of rollers
the axes of which are supported at each end by T shaped uprights which slide into
brackets fixed to the tie pieces of the machine.
The said uprights separate the pressure rollers from or bring them into contact
with the operating rollers by means of eccentrics, on which they rest. The motion
is communicated to them by a vertical shaft on the side of the frame, on the upper
end of which is mounted a fly wheel to which a rotary motion may be imparted by
the hand, and provided at the lower end with an endless screw which gears into a
wheel keyed on the shaft of the eccentrics, and this motion is transmitted to the
eccentrics of the hind uprights by two lever arms and a connecting rod.
The frame, carrying on each side the series of operating rollers, the shafts of which
revolve in brackets fixed to the said frame, is moved in a rectilineal reciprocating
motion, which is transmitted in a reciprocating circular motion to the two series of
operating rollers by means of straps fixed to a second frame. The ends of these
straps are fastened to two rows of pullies mounted on the shafts of the operating
rollers, one of which winds the strap in the direction in which the first-mentioned
frame works, and the other unwinds it, and vice versa, so that the said frame in its
reciprocating motion drawing the operating rollers from right to left, and from left
to right, winds
and unwinds the straps on the pullies and revolves or turns the
operating rollers in an opposite direction.
up
The reciprocating motion is imparted to the first fiame by a conical pinion keyed
on the driving shaft of the machine, which gears with a wheel mounted on a vertical
shaft, having at its other end a crank provided with a slide which slides into the
groove of the frame carrying the operating rollers.
A stretching roller covered with emery moves the stuff by means of a jointed
pressure roller, which by its weight presses the cloth cn to the stretching roller
which is actuated by a pinion mounted on the driving shaft of the machine which
imparts the motion to a wheel mounted on the stretching roller through two other
wheels and a pinion.

the said Henri Adrien Bonneville in the Great Seal Patent Office on the 14th
June 1878.
HENRI ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 18,
Rue de la Chaussée d'Antin, Paris, France, and 6, Piccadilly, in the County of
Middlesex, Patent Agent "A NEW OR IMPROVED NAPPING MACHINE" A com-
munication from abroad by François Delamare and Pierre Désiré Chandelier,
Machinists, two persons resident at Rouen, France.
The Invention relates to a new or improved napping machine arranged in such a
manner that all stuffs in general may be napped thereby, of whatever material and
however light, with a regular dressing without leaving any rays, a result which
it has been hitherto impossible to attain with machines of the systems already
known.
In treating light stuffs the points of the brass or iron fillet cards forming the
lining of the reciprocating rollers, and penetrating into the cloth or stuff, are only
engaged according to the degree of thickness of the stuff submitted to the operation,
and are afterwards disengaged by the reciprocating rotary motion imparted to the
rollers.
The Invention is illustrated in the accompanying Drawings, in which Fig. 1
represents a front elevation of the machine; Fig. 2, a side elevation of the same in
middle section; Fig. 3 and Fig. 4 are details which will be more fully explained
herein-after.
Similar lettors indicate corresponding parts in all these Figures.
The new or improved machine consists principally,-
1. Of rollers which keep the cloth stretched under the action of the operation
whilst at the same time delivering the required quantity.
2. Of rollers placed two-by-two on each side of the middle of the machine,
holding up the stuff during the operation of napping, and which are so arranged
as to be brought into contact with or separated from the operating rollers, as
need be.
3. Of a variable number, according to the width of the stuff, of rollers lined with
brass or iron fillet card placed at equal distances on each side of the machine, and
arranged across the stuff so as to operate in the empty space between the rollers
which hold up the stuff, each roller consisting of two parts, so that the hook of the
point of the one is in a reverse position to that of the other in order that by means
of the reciprocating motion the stuff may be worked as much one way as the other.
The points of the cards of the end rollers are always in the same direction, so that
in rotating they stretch the stuff in width and prevent it from being displaced.
4. Lastly. Of stretching rollers which change the position of the stuff as the work
is done.
The different parts of the machine are as follows:-The roller K. that crosses the
stuff holds it on the stretching roller L lined with fillet cards. The latter roller
carries on its axis a brake pulley acted on by a metal blade connected at a fixed
point to the frame of the machine, having at its other end a rod from which is
suspended a weight m which causes the metal blade to exercise a friction on the
brake pulley which gives the tension to the stuff by means of the stretching
roller L.
The stuff is kept in contact with the series of operating rollers J, J¹, by means of
the rollers M, M, M", M, the axes of which are supported at each end by the
T shaped uprights N, N', N", N, which slide into brackets fixed to the tie
pieces O, 0, of the machine.
The said uprights N, N¹, N,N, separate the pressure rollers from or bring them
into contact with the operating rollers J, J', by means of the eccentrics P, P¹, Pl, Pili,
on which they rest. The motion is communicated to them by a vertical shaft a on
the side of the frame on the upper end of which is mounted a fly wheel b, to which a

page_text: rotatory motion can be imparted by the hand, and provided at the lower end with
an endless screw o which gears into a wheel d keyed on the shaft of the eccentrics P,P',
and this motion is transmitted to the eccentrics of the hind uprights N", N", by
the two lever arms e, e', and the connecting rod f.
The frame H, carrying on each side the series of operating rollers J, J', the shafts
of which revolve in brackets h, h¹, fixed to the said frame, is moved in a rectilineal
reciprocating motion which is transmitted in a reciprocating circular motion to the
two series of operating rollers J, J', by means of straps i, i, fixed to the frame I, as
illustrated in detail, Fig 3. The ends of these straps i, i', are fastened to two rows
of pulleys j, j', mounted on the shafts of the operating rollers J, J', one of which
winds the strap in the direction in which the frame H works, and the other unwinds
it, and vice versa, so that the said frame in its reciprocating motion drawing the
operating rollers J, J', from right to left, and from left to right, winds up and
unwinds the straps i, i, on the pullies j, j', and revolves or turns the operating
rollers J, J, in an opposite direction.
The reciprocating motion is imparted to the frame H by a conical pinion G,
keyed on the driving shaft of the machine, which gears with a wheel & mounted
on the vertical shaft E, having at its other end a crank F provided with a slide G
which slides into the groove of the frame H carrying the operating rollers.
The stretching roller Q, covered with emery, moves the stuff by means of the
jointed pressure roller q, which by its weight presses the cloth on to the stretching
roller which is actuated by a pinion B mounted on the driving shaft of the
machine, which imparts the motion to the wheel q mounted on the roller Q through
the wheels B¹, B", and pinion B¹¹¹.
Fig. 4 represents a new arrangement of the operating rollers J, J, which are also
provided with a continuous circular motion, making them revolve in the opposite
direction, one of the other by means of a strap i moved by a pulley on the driving
shaft of the machine. Each operating roller J, J, has a small stripper R driven by
the same strap.
WORKING OF THE MACHINE.
The stuff being placed, as illustrated by the red line, Fig. 2, the machine is put in
motion by the driving pulleys A by means of the pinions and wheels B, B', B¹¹, B¹¹¹
which revolve the roller Q, which draws the pressed cloth to its circumference by its
jointed pressure roller q, and causes the stretching roller L to deliver the stuff to the
operation.
The conical pinion G mounted on the driving shaft, and its wheel D mounted on
the vertical shaft, impart the reciprocating motion by turning its crank to the
frame H, which by means of the straps i, ¹, acts upon the operating napping rollers,
as has been alieady described.
Having thus fully described 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 with
departing from the principle of the Invention, but what I claim is, the dressing and
napping by means of operating rollers lined with brass wire or iron fillet cards
placed across the stuff and provided with an alternating or continuous circular
inotion, substantially 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 Thirty-first day of May, in the year of our Lord
One thousand eight hundred and seventy-eight.
