Improvements in Double-acting Jacquard Machines for the Production
of Heavy Goods, such as Double Plush Goods for instance.
A communication from EMIL CLAVIEZ, of 8, Ziegelstrasse, Chemnitz, in the
Empire of Germany, Director.
I WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the County
of Middlesex, Civil Engineer, 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 following statement:-
The present invention has for its object a "Jacquard" machine with a positive
and negative action, and which is intended chiefly for the production of heavy
goods such as double plush goods. This machine is characterised especially in
that it combines in a certain degree two Jacquard machines acting positively and
negatively, of different construction, and which are so arranged that the adjustable
knife box is in the negative machine whilst the adjustable plate or wire tray
(German "platinenbod en ") is in the positive machine.
The new machine is shown on the accompanying drawings:
Fig. 1 being a front view of the Jacquard machine,
Fig. 2 a view taken from the work side of the loom,
Fig. 3 a front view from the left side,
Fig. 4 a section on II of Fig. 2.
The
The Jacquard machine is arranged on the upper part of the loom in a suitably
constructed framework G. and the parts to which regard is here had, are worked
from the shafts o o¹ o² which latter are themselves set in motion by the eccentric
rods g, l, r, the eccentrics of which are fastened on the picker shaft.
accompanying drawing by way of example shows the machine with 600 plates,
therefore a six hundred machine and its construction is more particularly as
follows,
The front plate or wire tray P is firmly, but adjustably, situated between the
two walls of the framework A Figs. 1 and 2. The knife box M. with its knives m
has at its head adjustment screws y, and which hold fast the cross rail w. The
latter carries on each side round bolts (Fig. 2) each of which receives a draw bar /
(Figs. 1 and 2). Further the lower parts of the draw bars h are each connected
with a lever i situated on the shaft o'. The requisite up, and down movement of
the knife box is effected by means of the lever k and eccentric rod / and of
pattern discs (tappets), so that by each up and down movement, the knife box
rises and sinks so as to work the front positive group of plates. For the steady
guidance of the knife box M it carries on both front sides, two rails u u
(Figs. 1 and 4) which are suitably guided in grooves of the framework a, a.
The negatively working part of the Jacquard machine has, as already mentioned,
a firmly seated but adjustable knife box, and a movable plate or wire tray. The
construction of this part of the machine is as follows:
The plate or wire tray P¹ moves in a similar manner to the previously mentioned
knife box M in guides u u (Figs. 1 and 2) and for carrying out its object is
provided with bolts projecting out of the walls A and these bolts serve for the
reception of levers m³, which latter are in turn connected with a second

page_text: lever a seated on a shaft o'. The up, and down movement of the plate or wire
tray P is also caused by lever g, and eccentric rod r. The bolts which project out
of the walls of the frame take into slots s (Fig. 1). In order to limit the downward
stroke of the plate or wire tray, a rail t is fastened to the walls of the frame on
each side. The second knife box M' is arranged in a fixed manner, but the same
can be adjusted at wish as regards height by means of four winged nuts v. This
is of especial value when plush work of different pile is to be produced, since by
adjusting the knife box of the negative machine, and the plate or wire tray of the
positive one it will be understood that a varying height in the chain or loops is
attained, resulting in a greater or lesser separation of the two pieces, and
consequently a higher or lower pile. As regards the movement of the pattern
cylinder 2, it may be mentioned that the same is journalled on two levers c and
swings on two bolts xx. The motion is effected by means of the rods b b
connected with the levers c c on each side (Figs. 1 and 4), each is connected with
a.slotted levere seated on the shaft o which latter in turn receives its swinging
motion from lever and eccentric rod g. The arrangement of the change hook d,
and needles n in the needle board N and spring barrel N' is similar to what is in the
ordinary Jacquard machine, and it is supposed that these parts will be readily.
understood.
In Fig. 3, the left side front view of the above mentioned parts is shown, and
which, owing to their concealment in Fig. 1, will be better understood from this
view. 'As regards the construction of the pattern card passing over the pattern
cylinder Z, it may be mentioned that the one half is formed positively and the
remainder negatively. By the first mentioned half the front part of the machine
comes into play, and by the second, on the, contrary, the rear half.
It will be understood therefore that by the intimate co-operation of both these
parts of the machine, a pure double plush or a so called German canderplush is
produced, and the more so, since on the shed of the pile being opened the pattern
or pile is pressed apart and interwoven throughout the entire breadth of the goods
owing to the double draw action.
The work capacity of the foregoing machine is further, considerably increased
since owing to the adjustability of the knife box or plate or wire tray as mentioned
at start, varying heights of pile, can be obtained.
The accompanying drawings show a machine built of, wood, but of course the
same can be made out of iron. The Jacquard machine can be constructed for any
desired number of plates or wires.
The movement of this Jacquard machine does not take place in the usual manner,
namely, by the draw bars 1r being moved 'up and down by means of eccentrics
which are fixed on the main shaft, but it is effected by pattern discs or tappets.
These discs have eccentric grooves in which are rollers fixed on movable or revolving
levers. The end of the lever which projects over the disc connected with a
drawbar for instance. On these discs being revolved, an up and down movement
is obtained as the roller travels up and down following the curve of the groove.
These pattern or round discs are already known, but have not yet been employed
for the purpose hereinbefore indicated. They are employed for operating this
Jacquard machine, because they allow the speed of the rising or falling of the
machine to be varied as desired by altering the form of the grooves, so that during
the movement of one balf of the Jacquard machine, the other half remains absolutely
stationary. By means of these two parts of the Jacquard machine and owing to
the advantage above named, any collision of the warp threads of both goods is
prevented, as one warp is drawn into the front part, and the second into the rear
part of the Jacquard machine. From the foregoing description it is evident that
one part of the Jacquard machine moves only when the other is stationary. The
result of this is that the warp threads of both goods (the upper and lower goods)
cannot cross, whereby on the one hand the material is very little affected and on
the other hand a clean shed is obtained, so that with this Jacquard machine a pure
double plush of constant height of pile may be produced.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A double acting Jacquard machine for the production of figured double plush.
(canderplush) of any desired height of pile, characterized by the arrangement of a
fixed and of a movable and adjustable plate or wire tray (P and P¹) sliding in,
guides and by means of suitable intermediate parts (m², a, q, r) in combination with
a fixed but adjustable knife box (M¹) and another one (M) moving up and down
in suitable guides by means of lever mechanism, both which parts work the plates.
or wires (p or p¹) in such manner that by means of the intimate co-operation of
the card cylinder (Z), knife box (M or M¹) and plate or wire tray (P or P¹), the
pile is held throughout evenly apart and interwoven, whilst at the same time the
knife box or the plate or wire tray can be adjusted and thus any height of pile be
produced, and by an arrangement of eccentric or pattern discs a crossing of the
threads of the upper and lower goods be prevented, as well as by a rising and
falling, as required, of the Jacquard machine and on the standing still of the one-
half of the same, the movement of the other is brought about, or vice versa.
All substantially as hereinbefore described and shown on the accompanying
drawings.
