page_text: WHEREAS I am in possession of an Invention for "CERTAIN IMPROVE-
KENTS IN MACHINES FOR CUTTING TEXTILE AND OTHER MATERIALS," communicated
to me by Albin Warth, a person resident at Stapleton, State of New
York, and William Frederick Jobbins, a person resident at the City and
State of New York, United States of America, 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 carried into effect, reference being
had to the accompanying Drawings, and to the figures and letters marked
thereon, that is to say :-
This Invention consists in combining with a knife carrier a revolving
and sliding shaft, said knife carrier being allowed to turn round an axis
at right angles to the direction of the sliding shaft in such a manner
that by the said shaft the required motion is imparted to the knife, and
at the same time the knife carrier, together with the knife, can be
carried in any direction against the material to be cut.
Also in the combination of a mechanical feed with a knife carrier and
a sliding and revolving shaft in such a manner that the knife, which
receives the required motion by the action of the revolving shaft, is fed
automatically towards the material to be cut.
Further, in combining with the knife carrying bar a hollow tubular
guide rod, which forms the bearings for the gear connecting said knife
carrying bar with the driving shaft, and to which is secured a handle in
such a manner that by turning said hollow guide rod the knife can be
turned in any direction without throwing it out of gear with the driving
shaft.
Also in the combination of a throat plate with a revolving sliding shaft
and a knife carrier, said throat plate being provided with a socket, one
or both edges of which form cutting edges to co-operate with the cutting
edge of the knife in such a manner that said throat plate follows the
sliding motions of the shaft in either direction and forms the support

for the material to be cut in whatever position the knife may be
brought.
Further, in a bracket rising from the throat plate and forming the
support for the tubular guid rod of the knife carrying bar and for a shaft,
which is geared together with a sliding and revolving shaft, and from
which motion is imparted to the knife carrying bar, said bracket being
provided with a handle in such a manner that the throat plate, together
with the cutting mechanism, can be conveniently guided to follow the
pattern to be cut out.
Also in a hinged lever connected to the bracket of the throat plate,
and forming the bearing for a pin which supports the feed wheel, in
combination with a cam which receives a rotary motion from a sliding
revolving shaft, and from which motion is transmitted to the feed wheel
in such a manner that the feed wheel is always in gear with the sliding
revolving shaft in whatever position the throat plate may be brought,
and that by raising the hinged lever the feed wheel can be adjusted to
the thickness of the material to be cut or lifted clear above said
matherial.
Further, in a finger or index hinged to the centre pin of the feed
wheel, said pin being secured in a hinged lever, while the finger extends
in front of the knife for the purpose of indicating the direction in which
the knife is to cut.
Also in an universal swivel head in combination with the sliding and
revolving shaft, and with the throat plate carrying the cutting me-
chanism in such a manner that the sliding and revolving shaft, together
with the parts attached to it, can be swung or moved in any desired
direction without throwing it out of gear with the driving shaft, and by
these means the knife is free to accommodate itself to the position or
nature of the material to be cut.
Further, in combining with the throat plate the rotating knife and
the sliding and revolving shaft a standard which carries a handle, and
rises from the throat plate and forms the bearings for the spindle of the
knife, while its upper portion is round and fitted into two sleeves,- one
inside the other, the first sleeve carrying a double cog wheel that serves
to transmit the rotary motion from the sliding and revolving shaft to
the rotating knife, while the second sleeve forms the support for one

page_text: end of the sliding and revolving shaft in such a manner that the throat
plate, together with the rotating knife, can be turned round in either
direction without being thrown out of gear with the sliding and revol-
ving shaft, while at the same time the sliding motions of said shaft aro
transmitted to the cutting mechanism.
Also in the arrangement of a double sectional cog wheel in combina-
tion with the throat plate, the rotating knife, and the sliding and
revolving shaft in such a manner that the said cog wheel can be readily
adjusted to knives of different diameter, and that when the knife wears
off, and has to be moved closer to the throat plate, the double cog wheel 1
can be adjusted accordingly.
Also in the arrangement of a sharpening stone or other sharpening
device in the slide of or connected to the feed wheel, said sharpening
stone being made to act on the side of the rotating knife in such a
manner that as said knife revolves its cutting edge is continually kept 1
sharp and at the same time by the motion of the feed wheel a constantly
varying surface of the sharpening stone is presented to the knife.

-In-the-Drawing-the-letter-A-designates-a-table-from which riscs tho
swivel head B, which supports the sliding and revolving shaft O. Said
swivel head consists of a tubular, standard a, which is provided with a
bottom flange b to fit into a grooved bracket c which is firmly secured to
the table A, the tubular standard à being free to rotate in said bracket.
In the mouth of the tubular standard.a is fitted a plate d, which swings
between centre points e (see Fig. 3), and from which rise two standards f
that form the bearings for a tubular shaft g. By means of the centre
points e this shaft can be swung up or down, and brought in any desired

page_text: inclination towards the table A, while the tubular standard a allows the.
same to turn freely in either direction in a plane parallel to the surface
of the table.
On the tubular shaft g is mounted a pulley which connects by a
belt i with a pulleyj mounted on the driving shaft D that has its bear-
ings in boxes secured to one of the legs of the table A, and which
receives motion by a hand crank, or by a treadle, or by any other suitable
means. The pullies h and jare grooved, so that when the standard a is
turned round the belt i will not be thrown off.
The tubular shaft g is bored out to receive the sliding shaft C, which
is by preference made triangular, but which may be formed in any
desirable manner so that it will not turn in the tubular shaft while it is
free to slide therein.
The sliding motion of the shaft C is facilitated by friction rollers k
which project through the sides of the tubular shaft g and bears from
different sides against the sliding shaft C (see Fig. 4). One end of
said sliding shaft is turned of round, and it has its bearing in a bracket E
which extends from a sleeve F fitted on the hollow guide rod G of the
knife carrying bar H. This hollow guide rod is supported by a standard I
which rises from the throat plate J, said standard being provided with an
annular bracket 1 (see Fig. 1) that is screwed up against a flange on
the bottom end of the hollow guide rod, and on said flange rests a double
cog wheel K, which is dropped loosely on the hollow guide rod beneath
the sleeve F, said sleeve being bored out to receive the tubular hub of
the cog wheel. The upper cogs of said cog wheel gear into a pinion m
mounted on the end of the sliding shaft C inside of the bracket E, 'said
shaft being prevented from sliding in the bracket by the pinion on one
end and by a screw ring n on the other side of said bracket. The lower
set of cogs of the cog wheel K gear into a pinion o which is mounted on
a shaft p that has its bearings in a bracket g extending from the.
standard I of the throat plate. On this shaft is also secured a disk r
carrying an eccentric wrist pin that connects by a rods with the knife
carrying bar H, which moves up and down in grooves & in the hollow
guide rod G, and as the shaft C is revolved a reciprocating motion is
imparted to the knife carrying bar.
L is the knife, which is by preference cut or stamped out of sheet .
"

page_text: means, the front edge of the knife being so adjusted that it coincides
with the centre line of the hollow guide rod, so that by turning this
guide rod the front edge of the knife remains in the same plane. The
lower cutting edge of the knife is inclined, and it co-operates with a
cutting edge u formed on one side (or on both) of a knife receiving |
socket or throat in the throat plate J.
From the bracket q which supports the shaft p extends an arm w,
which terminates in a ring and may serve as the handle for guiding the
mechanism during the operation of cutting, or if desired an additional
handle w* may be secured to the upper end of the tubular guide rod G
(see Fig. 2). On one side of the arm w is secured a lever a¹, one end of
which bears on the surface of a cam 6' (see Fig. 1 & 6) mounted on
the shaft p, while its opposite end bears against the arm c¹ of a bell-
crank lever c³, d³, the arm d' of which carries a pawl e¹ that engages
with the teeth of a ratchet wheel f¹. A spring g* which actes on the
pawl e¹ serves to keep the lever a¹ in contact with the cam 6'. The
ratchet wheel f' is mounted on a pin g¹, and it is firmly connected to
the feed wheel ¹, the pin g' being secured in a lever that swings on
the shaft p on the side of the arm to opposite to the lever a¹ (sec Fig. 6).
From this lever extends a thumb piece j', so that the same can be a
raised, while a spring / bears on said lever and serves to depress the
feed wheel h¹ towards a serrated roller which is mounted in the throat
plate. A stop pawl m³ prevents the ratchet wheel f¹ and the feed
wheel h¹ from turning in the wrong direction.
As the shaft p revolves an intermittent rotary motion is imparted to
the feed wheel h¹, and if the material to be cut is held stationary the
cutting mechanism is fed automatically towards said material, the throat
plate J being placed beneath it, so that by co-operation of the cutting
..edges of the knife and of the throat the cutting is effected. The throat
plate may be constructed with one or more caster rollers on its bottom :
surface, so that it whill move easy on the table A, and it may be curved as
shown in Fig. 2, or it may be made in the shape of a flat plate, cither
oblong or in any desirablo form.
-This machine is of particular value for cutting out such goods-where
it is most convenient to move the cutting mechanism towards the
material to be cut, and since the cutting mechanism can be easily moved
or turned in either direction it is possible to cut out patterns of any

page_text: desired form or shape. An index or finger m³ which is hinged to the
ping' enables the workman to guide the course of the knife with ease
and facility. This index straddles the knife, and it bears down upon the
material to be cut by its own inherent gravity, being free to adjust itself to
the varrying thickness of said material while the pin g', which forms the
bearings for the feed wheel and also for said index, rises and falls in
accordance with the increased or diminished thickness of the material to
be cut.
If desired the feed mechanism can be dispensed with, and the cutting
mechanism may be directed entirely by the action of the workman, who
can turn the same in any desired direction, or draw it out or push it in
as the formation of the pattern may require.
When a rotating disk knife is used in place of the reciprocating knife
the rod G is made solide (see Fig. 7 & 8), and it is supported by a
standard I which rises from the throat plat J, said standard being pro-
vided with a flange (shown in Fig. 8 and in Fig. 7 in dotted lines) that
is provided with a hole to receive the rod G. On the flange rest a
double cog wheel K, which is dropped loosely on the rod G beneath the
sleeve F, said sleeve being bored out to receive the tubular hub of the
cog wheel. Said cog wheel is provided with teeth on its upper and
also on its lower surface, and it is made in two sections which fit into
each other like telescope tubes, so that by drawing the inner section out
the distance between the upper and the lower set of cogs can be
increased, and vice versa. The two sections of the cog wheel K are
secured in the required position by set screws a². The upper cogs of
said cog wheel gear into a pinion m mounted on the end of the sliding
shaft C inside of the bracket E, said shaft being prevented from sliding
in the bracket by the pinion on one and by a screw ring. n on the
other side of said bracket. The lower set of cogs of the cog wheel K
gear into a pinion o which is mounted on a shaft p that has its bearings
in a bracket q extending from or forming a part of the standard I of the
throat plate. On a this shaft is also secured the circular disk knife L, and
as the sliding shaft O is revolved a rotary motion is imparted to the disk
knife. The cutting edge of the knife co-operates with a cutting edge
formed on the side of the throat in the throat plate J. From the
bracket 9 which supports the shaft p extends an arm w, which may serve
as the handle for guiding the mechanism during the operation of cutting,
or, if desired, an additional handle w* may be secured to the upper end

page_text: of the rod G (see Fig. 8). On one side of the arm w is placed a lever a¹
which has its fulcrum on the shaft or spindle p, and in which is secured a
ping' that forms the bearings for the feed wheel h¹. On the inside of
this feed wheel is fastened a cog wheel 6' which is geared together by an
intermediate pinion c¹ with another pinion a mounted on the spindle p, 5
so that said feed wheel receives a continuous revolving motion in the
same direction with said spindle. A spring * which acts on the lever a¹
serves to depress the feed wheel towards a serrated wheel / which is
mounted in the throat plat. As the spindle p revolves a constant rotary
motion is imparted to the feed wheel ', and if the material to be cut is 1
placed beneath the feed wheel and held stationary the cutting mechanism
is fed automatically towards said material, the throat plate J being
placed beneath it, so that by the co-operation of the cutting edges of the
revolving knife and of the throat the cutting is effected.
The throat plate may be constructed with one or more caster rollers 1
on its bottom surface, so that it will move easy on the table A, and it
may be curved, as shown in Fig. 8, or it may be made in the shape of a
flat plate, either oblong or in any desirable form. In the front side of the
feed wheel is secured a sharpening stone or sharpening device m³, which
bears against the side of the disk knife and serves to keep the cutting 2
edge of the knife sharp. As the sharpening device revolves with the
feed wheel it presents a constantly varying surface to the knife.
If desired, the feed mechanism may be dispensed with, and the cutting
mechanism may be directed entirely by the action of the workman, who
can turn the same in any direction or draw it out or push it in as the 2
formation of the pattern may require, so as to cause the knife to follow
the contours of the pattern.
