Improvements in Machines for Cutting Cloth, Leather, Pasteboard
and the like, particularly applicable for Cutting and Bundling
Samples.
I, GASTON DETRAIGNE, of 154, Faubourg Ceres, Reims, France, Manufacturer,
do hereby declare the nature of this invention to be as follows:―
The object of the present invention is a machine for cutting cloth, leather and
the like into pieces according to the form of the knives fitted to the machine as
well as for the bundling of these cuts or samples; the tissues or other like material
are placed the one on the top of the other to a certain number and are cut and
bundled together with one single cut.
The machine is essentially composed of a framing in wood or cast iron the top
of which has the shape of a table and on to which a press is fastened constituted
of a vertical body which is bent forward and overhangs at right angles the table of
the framing so as to serve as a support and guide to the functioning organs of
the cutting-tool.
Upon this framing there slides horizontally a sliding-carriage in the direction of
the depth of the machine this sliding-carriage itself being surmounted by a second
sliding-carriage which is able to slide horizontally across the first, but in a
perpendicular direction to the throw of the latter and in such a manner as to
permit the successive conveying under the knife, which works vertically, of all
those parts of the surface of the tissue which are to be cut.
The lower sliding-carriage, the one which reposes directly under the framing by
means of slides, is operated by a rod chased with a rapid thread and worked by a
hand wheel.
The second sliding-carriage covering the former and sliding over it is put into
gear by a toothed-wheel catching into a small toothed rail applied below the
sliding-carriage, the toothed-wheel being able to slide on to the shaft which makes
it turn whilst it is carried along by the lower sliding-carriage, thus being able
to operate in all the positions of last mentioned sliding-carriage; this shaft having
at its extremity a ratchet-wheel functioning by the wheels which cause the cutting
tool to operate.
A wooden table is fitted on to the upper sliding-carriage to hold the superposed
tissues which are to be cut.
The cutting-tool is composed of a knife movable at will according to the form
of the cutting to be effected being fastened by a thumb-screw on to the toolholder
which is itself fixed on to a vertical rod, propelled by a vertical alternating motion
which is conveyed to it by a framed eccentric-lappet by means of a set of cog-
wheels, the first of which receiving its motion from a hand-crank worked by the
workman or by a transmission-pulley in case a prime-mover is employed.
The toolholder which is therefore functioning vertically has vertical rods
screwed on to the pressing-plates which are placed lower than the knife. These
rods being encircled by strong spiral-metallic springs, are able to slide up into

page_text: the toolholder; when the latter descends the pressing-plates come down on the
tissues before the knife, thus pressing them firmly together so that the tissues
are cut with absolute neatness, and allows of the knife being removed while
ascending.
The knives may be altered according to the cuts required and consequently the
pressing plates are likewise alterable being constructed according to the shape of
the knives used.
Pressing-plates may be employed independent of the toolholder, they are then
supported by a double armed lever finished at the base by a treadle functioning by
the mechanic's foot.
At the same time that the knife operates, a piercer forming part of the tool-
holder forces into the superposed tissues which are to be sampled, a small wire
hook which makes a bundle of the portion cut.

Improvements in Machines for Cutting Cloth, Leather, Pasteboard
and the like, particularly applicable for Cutting and Bundling
Samples.
I, GASTON DETRAIGNE, of 154, Faubourg Ceres, Reims, France, Manufacturer,
do hereby declare the nature of this invention, and in what manner the same is
to be performed to be particularly described and ascertained in and by the follow-
ing statement:-
The present invention concerns a machine for cutting regular pieces, of suitable
dimensions in strips of superposed cloth or other stuffs, by means of knives of a suit-
able shape with the object of obtaining samples which are, at the same time,
. attached together to form bundles.

Figs. 9-11 show different vertical sections of the same apparatus and
Fig. 12 shows a binding clasp.
This cutting machine is composed essentially of a wooden or cast iron frame B,
upon which a press body A is fixed as shown in Figs. 1 and 2.
The frame B supports two superposed carriages CD the lower carriage O being
provided, on its lower face with bearings E sliding on flat rails F fixed on the
frame B and provided with cylindrical rods d passing through the bearings and
serving as guides to them. The carriage C has also on its lower face a socket I
wormed inside. A wormed rod H passes through the socket I the said rod bearing
a hand wheel G at its outside extremity and turning in a bush e fixed to the frame
(Fig. 4).
The upper carriage D is arranged tranversally with respect to C and slides on
two support rods J and three rails K which, as also the rods J are fixed on the top

page_text: of the lower carriage C; moreover, the carriage D has its upper face hollowed to
receive a board on which the cloth is cut.
Under the carriage D a rack L is fixed which gears with a toothed-wheel M
fitted inside the socle of the machine (Figs. 3 & 4).
This wheel M passes over the carriage C in a groove made in this latter and is
placed between 2 guides P fixed underneath the carriage C, moreover it can be
displaced longitudinally on its shaft N which draws it by means of a fixed cotter O
fitted in a groove of the shaft and protruding on the outside (Figs. 3 & 4).
The shaft N is supported by the frame of the machine through the whole length
of which it passes and bears a ratchet-wheel Q placed behind the machine on its
rear extremity, and on its fore-part a cog-wheel f¹ gearing with a pinion f" fixed
on an axle which bears the working-wheel V at its back end.
Between the fly-wheel Z, mounted on the shaft S, and the frame of the machine,
a cog-wheel U is fixed and works by means of an endless chain Y, the cog-wheel Vi
which is fixed at the back of the apparatus on an axle k, which also bears a spur-
pinion X, which gears with the cog-wheel X¹.
On the axle of the wheel X' another spur pinion A¹ is wedged, working the
wheel B on the axle of which a cog-wheel D¹ is fixed, which, by means of the end-
less chain e, works the wheel d whose axle bears, at its back extremity the
crank plate f which is provided with an axle l bearing the head of the connecting
rod g whose other extremity is jointed at m with a frame n through one end of
which the shaft N passes, upon which it turns freely.
In the interior of the frame n a catch E is fixed articulated with it and which
works, in one direction only, a ratchet wheel Q fixed on the back end of the shaft N
(Figs. 2 and 3).
The axles k, and C rotate in supports fixed to the body of the press A and
the upper axle C has on its front extremity a crank-plate F1 provided on its back
face, with a stud G₁ fixed on the plate by means of a bolt and fitted inside the
frame H¹ which bears, on its upper side, a rod I¹ guided by the socket J¹, and on
its lower side a square rod K¹ passing through the square socket L¹ and to the lower
end of which the knife holder M' is fixed (Figs. 1 and 2).
The square socket L¹ has on its lateral sides, screws serving to regulate it to
secure a perfect guiding of the frame H¹ (Figs. 1 and 2).
The knife-holder M which is fixed on the rod K¹ by means of 2 screws N¹, is
composed of a part M1 in the form of a fork and whose 2 branches are provided
with lateral extensions O¹ in which longitudinal slides are made allowing vertical
sockets P¹ to be drawn together or set further, these sockets being held by double
plates A provided with screws or bolts (Figs. 1 and 5).
Sliding rods S¹ pass through the sockets P¹ the said rods being provided with
powerful spiral springs and the sockets are screwed at their lower extremity into
a pressing plate T¹ of a shape which suits that of the outside of the knife (Figs. 5
and 6).
The knife-holder M has a groove at its lower end in which the upper part of
the knife U is fitted, this knife being fixed by means of the screws ql and of cast
iron holdfasts s. These holdfasts are fixed on the side of the knife-holder and form
a box R¹ with this latter, divided into 2 parts by a transversal part P" which is
held by means of screws and is traversed by a cylindrical rod Sú which passes to
the interior of the knife U₁ and is screwed at its lower end into a pressing plate T¹¹
of a shape suiting that of the interior of the knife and whose upper face is pressed
by a strong spiral spring arranged on the rod S" (Figs. 5 & 6).
The pointer Z is placed on the inside of the knife holder M' and of its knife,
and it is fixed on the upper face of the pressing-plate T. This pointer shown in
Figs. 5, 6, 7, 8 and 9 is composed of a vertical prism Z¹ provided on the inside with
a chamber A" and having a lateral opening Bu through which the brass binders Cu
are introduced. Above the chamber A", in the part 7', a slide D is made, in
which a repelling rod E slides, this rod having its upper end fixed to a cross-
piece G which is guided by 2 vertical rods F" provided with spiral springs and

page_text: fixed by their lower ends to the part 7. The cross piece G¹ has a steel head t
on its upper face, against which a small hammer H1 strikes, the said hammer being
fixed to the interior of the knife-holder box R'; and whose height can be regulated
at pleasure by making it slide in a slide I¹ made in a side of the box R¹.
The cutting machine works as follows: the cloth or other material, card-board,
leather etc. being placed on the table R, of the carriage D, the working wheels V
and G are turned so as to displace respectively the carriages 1 and C in a suitable
way to bring the cloth to the required place under the knife U which is previously
fitted in the knife-holder M. The apparatus is then worked by communicating,
by means of the fly-wheel T, a rotary movement to the axle S, which through the
cog-wheels and intermediary chain, transmits its movement to the crank-plate F
(Figs. 1 and 2) and this latter works the frame H¹ the object of which is to trans-
form the movement of H into an alternate rectilineal movement which successively
produces the raising and lowering of the knife-holder M¹.
During the downward movement, as the plates T and T are placed lower than
the knife U they reach the cloth before it and operate a pressure on it hich
increases according to the descent of the knife holder M' so that the knife U' on
reaching the cloth which is strongly pressed, cuts it very neatly (Figs. 1 and 2).
The rotation of the apparatus continuing, the knife holder rises and easily leaves
the cloth, this latter being held by the plates T¹ T" which at this mon nt form a
repeller.
During the downward movement of the knife, the frame n worked by the con-
necting rod a moves in such a way that the catch E slides on the ratchet-wheel Q
without working it. When the knife rises, the catch returns in a reverse way
and works the wheel Q which produces a rotary motion of the axle N and conse-
quently of the wheel M. This latter, through the rack L, moves the carriage D
forward the length of a fresh cut and the apparatus continues as above.
When the cloth has been cut thus to the end of the carriage D this latter is
brought back to its initial position by means of the fly-wheel V then the carriage C
is moved forward by means of the wheel G the width of one cut and the apparatus
is again ready for work.
With this latter operation, to observe his distance, the workman looks at a
needle fixed on the edge of the carriage C and which, displacing on a divided
rule u fixed to the table R shows him the width of the cut."
The pointer works as follows:
When the knife holder M descends, the pressing plates T T are fixed on the
cloth placed on the table R; then the knife-holder M continuing its descent, the
hammer H forming a body with it, strikes the head t of the cross piece G₁ of
the repeller E which, in its turn obliges the binder Cu to penetrate into the cloth.
The ends of this binder then come into contact with a small metallic case J1 fixed
on the table R and which obliges the points of the binder to bead so as to form
the bundle, (Fig. 7).
The cases J are arranged on the wooden table at certain distances, according
to the dimensions of the cuttings at the exact place where the binder must be
placed; for this purpose, it is well to make use of different. tabies R according to
the work to be executed.
With this machine, the pressure on the cloth may be obtained by an organ inde-
pendent of the knife-holder and shown in the subjoined drawing (Fig. 2).
This arrangement consists in a double elbowed rod h whose upper arm is provided
with a press plate a and the lower arm with a pedal p which the workman works
with his foot.
The vertical arm of the rod is held by 2 support sockets b fixed to the frame of
the machine and provided inwardly with a groove in which a wedge is fitted, the
object of which is to hold the rod h in the desired position.
The cutting-machine may also be worked by a motor by substituting the cog-
wheel V by a pulley worked by the motor by means of a belt.
This same machine may also be used for cutting paper, card-board, leather etc.;

page_text: for this purpose it suffices to increase the power of the machine in proportion to
the resistance of the material to be cut.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
A machine for cutting cloths, card board, leather etc. distinguished by the
combination of:
A frame upon which a press-body is fixed; 2 superposed carriages the lower of
which is arranged longitudinally and the upper transversally; rails and rods to
support and guide the carriages; a threaded rod provided with a working wheel
to work the lower carriage a longitudinal axle having at its fore-end, a working
wheel at its back end a catch wheel and at its middle part a movable gearing-
wheel arranged longitudinally between two guides fixed under the lower carriage,
and gearing with a rack fixed under the upper carriage to work this latter; a
longitudinal axle having at its fore-end, a handle to work it, and at its back
extremity a regulating-wheel and a cog-wheel; a series of cog-wheels endless-
chains and intermediary shafts to work the different organs; a crank-plate fixed
on an intermediary axle and working the catch of the ratchet-wheel by means of a
connecting-rod; a frame properly guided and transforming the continuous circular
movement of a crank-plate fixed on the top axle of the machine, into an alternate
vertical movement; a tool-holder fixed on the lower rod of the frame; a knife
fixed to the holder; pressing plates screwed on rods provided with spiral springs
and sliding in the tool-holder; a pointing-tool composed of a hollowed part and
provided with a lateral opening; a repelling rod guided and lifted by two rods
provided with spiral springs and a hammer fixed to the knife holder, the said knife
being changed ad libitum, and the object of which is to cut the cloth or other material
placed on the top carriage and pressed by the pressing plates during the descending
course of the knife before this latter reaches the cloth, and the pointing tool serving
to penetrate a binder into the cloths, the said binder serving to form a bundle of
the strips of cloth; the said machine can also be worked by a motor or any other
mechanical power by substituting one of the intermediary cog-wheels by a pulley
worked by a belt, and the pressure on the cloths can be operated by an organ
independent of the tool-holder and consisting of a doubly elbowed lever and pro-
vide with a pedal and a pressing plate.
