A New and Useful Power-loom.
I, FELIX MEYER, of 78 Wilhelm Street, Aix-la-Chapelle, Rhenish Prussia, Germany
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:
My invention relates to a new and useful power-loom by means of which two
or more webs can be woven at the same time and the objects of my improvement
are, first, to provide two or more warp-beams, in order to arrange two or more warps;
second, to provide a correspondent number of mountings to operate the said warps
at the same time; third, to arrange a lathe provided with two or more reeds to
conduct the single warps, and with the same number of races for the flying-shuttles;
fourth, to provide a picking-shaft that can operate two or more drivers at the same
instant and with the same velocity; and finally, to arrange two or more cloth-
beams the upper ones of which can be displaced in an upward direction. I attain
these objects by means of the mechanism illustrated in the accompanying drawing,
in which
Fig. 1 is the front-view of the shuttle-box with two flying-shuttles, a picking-shaft
provided with two drivers and connected to the said shuttle-box of the lathe provided
with two reeds and the equal number of races.
Fig. 2 is the side-view of the new power-loom without the frame and shows the
arrangement of the warp-beams and cloth-beams, the warps, the mountings, the lathe
provided with two reeds and races.
Fig. 3 represents the front-view of the displacing mechanism for the upper
cloth-beams.
O
Figs. 4 and 5 show on a greater scale the top-view and the front-view of the
picking-shaft provided with two drivers.
Fig. 6 represents, on a greater scale too, the cross-section of the lathe, and finally,
Fig. 7 shows the driving mechanism of the upper cloth-beam.
Similar letters refer to similar parts throughout the several views.
The warps K, K, arranged on the warp-beams A, A, and operated by means of the
mountings G, G, are guided one above the other through the slays R, R, of the lathe L
to the cloth-beams W, W2.
Above the lowest cloth-beam W, ordinarily arranged, is mounted the ordinary
breast-beam B, for guiding the web T, to its cloth-beam W₁.
In order to unveil, in case of rupture of a thread or to control from time to
time the web, the lowest web T₁, which is generally hidden to the weaver by the
upper web, there is arranged the upper cloth-beam W, to be displaced in a vertical
direction.

The breast-beam ordinarily used to guide the cloth to the cloth-beam, is replaced
by two small shafts w₂ to maintain a constant tension in the web T2, when its
cloth-beam will be displaced upwardly, as represent the dotted lines in Fig. 2.
The upper cloth-beam W, is operated with the same velocity, but in an opposite
direction by means of the ratchet-wheel ra, operated by the long click c. arranged
besides the hitherto used click c₁ for operating the inferior cloth-beam W₁ in the well
known manner, the said ratchet-wheel rg, driving by means of the toothed wheels tot
the upper cloth-beam W, (Fig..3 and 7).

The axle-tree of the upper cloth-beam reposes at each side of the machine on a
lever H, (Figs. 2 and 7, that is to be turned round a fixed centre (O), situated
between the geometrical axis of the aforesaid guiding-shafts-or-rollers w₂, so that the

page_text: line of contact of those shafts forms the turning axis of the lever H. The other
extremity of the lever H bears on a sinall studs a die d provided on the opposite sides
with gudgeons F, on which are arranged the branches of the upper forked extremity
of a vertical rod S.
The inferior forked extremity of the rod S embraces a similar die d₁, that is
arranged on a little stud si being the end of one branch of a rectangular bent lever E,
that may be turned round the fixed centre N.
The construction of the mechanism for displacing the upper cloth-beams is best to
be seen from Fig. 3, which shows that mechanism in front-view with regard to the
power-loom.
In the front of the power-loom there is arranged the reversing-lever H₁ provided
with a spring-acted lock-bolt 1, and to be turned round the axle a along the toothed
segment e, in which the lever H, may be secured in any position by means of the
spring-acted lock-bolt 7.
Tho
Near the handle of the reversing-lever is fastened to the latter a spring f,
pressing the piece 9, arranged to be turned round the small stud on the reversing-
lever.
The piece 9 has a small rectangular branch 92, the extremity of which bears a
little studi, on which is arranged the connecting piece m of the lock-bolt.
lock-bolt can,
when the piece is pressed towards the handle of the reversing-
lever H₁, and consequently its rectangular branch turns round th stud in the
direction of the arrow i, slide upon the flat-side of the reversing-lever an I is guided
on it by means of a bent-plate p, embracing the bolt and secured to the reversing-
lever.
'1
At equal distances from the turning-centre a of the reversing-lever H₁ are
disposed on small studs g two connecting rods u the other extremities of which
are fastened to a branch w of a bent-lever E, being arranged at both sides before
the power-loom.
The other branch w of that bent-lever is provided on its exiremity with a small
stud s₁, bearing a perforated square d₁, that is provided on its opposite sides with
small gudgeons to be embraced by the branches of the forked inferior extremity of
the rod S.
The undermost reed R₁ is ordinarily fastened with its inferior extremity in the
lay-beam hearing the race b, whilst its upper extremity is arranged in a cross-bar k in
which is fixed too, the undermost end of the upper reed R₂, the upper extremity of
which being fastened in the lay-cap C.
The said cross-bar & bears the race b, for the second shuttle (Figs. 1, 2 and 6).
In Fig. 1 the springs at the chambers of the shuttle-box containing at the repre-
sented moment the shuttles are withdrawn, in order to show in the clearest manner
- the picking-shaft with drivers.
The construction of the picking-mechanism is best to be seen on a greater scale
from Figures 4 and 5.
The pickers P1 P2 are adapted to slide on the horizontal rods e₁ e, connected to the
shuttle-box.
The two pickers are joined by means of a vertical cross-piece Q, that is slotted
at D¹.
A small stud U, fastened to the picking-sbaft can vertically reciprocate in the said
slot D', when the picking-shaft is beating (oscilating) and the pickers horizontally
reciprocate on the rods e₁ e.
Now I may be permitted to explain the operation of the new power-loom.
The mountings G₁ G, operate the warps K, K, in the ordinary and well known manner
and independently of each other, so that the kind of weaving must not be necessarily
the same for both cloth.
The inferior web is woven in the same way as hitherto, while the upper cloth is
guided through the second reed R, to the small shafts or rollers w₂. Fig. 2 shows
that the undermost cloth T₁ generally is hidden to the weaver by the upper cloth T..
In order to avoid faults in the undermost web T₁ as will be caused by the rupture

page_text: of threads and the like, the weaver is obliged to control from time to time the
manufacturing of this web.
For this purpose he elevates the cloth-beam W₂ into the position indicated by
dotted lines in Fig. 2 by turning the reversing-lever H (Fig. 3) from the right to
the left side by disengaging the lock-bolt 7, sliding along the flat-side of the said
lever, from the toothed segment e and afterwards turning the reversing lever to the
desired position, where he leaves off the handle of the reversing-lever thus permitting
the lock-bolt to engage again the toothed segment e and to fix the reversing lever
and with it the connecting rods u, the bent-levers E in a certain position. By this
operation the forked rods S may be put up or down at will and the lever displaced in
a vertical direction.
By means of the said rods S, being connected to the lever H bearing the upper
cloth-beam W2, the latter can be fixed in any position moving in a circular direction
round the axis O of the lever H.
The ratchet-wheel ₂ being arranged in this lever H too, consequently makes a
similar movement like the cloth-beam W, and its driving-click (Fig. 2 & 7), which is
fixed on the axle of the under small click (c) and being pressed toward the ratchet r
by means of a small spiral spring y, is obliged to communicate to the circular
vertically movement of the ratchet-wheel r, and to operate it in any position.
The operation of the picking-mechanism may be seen in the Fig. 1 and 4.
When the picking-shaft F makes an oscilating rotation, the stud U, fastly connected
with it, reciprocates in a vertical direction in the slot D', of the connecting-piece Q, so
that the pickers or drivers P₁ P, may equally slide on the horizontal rods e, eg with
sufficient play and consequently the shuttles are driven at the same moment and with
exactly the same velocity.
Having now particularly described and ascertained the nature of my said invention,
and in what manner it is to be performed I declare that what I claim is-
1. The manufacturing at the same time, of two or more webs of the same or
different kind by means of just as many separate warps in the same power-loom.
2. In a power-loom for weaving two or more webs at the same time, with the
mainframe of the machine the combination of two (or more) warp-beams, two (or
more) warps, two (or more) mountings, a lathe provided with two (or more) reeds
and just as many races, two (or more) cloth-beams, a breast-beam, to guide the web
to the undermost cloth-beam, one (or more) pairs of small shafts or rollers to guide
the upper webs to the cloth beams, means for displacing the upper cloth-beams in a
vertical position and means for operating two (or more) shuttles at the same moment
and with the same velocity, essentially as set forth and for the purpose specified.
3. The combination with a power-loom for weaving two or more webs at the
same time, of one or more levers bearing the cloth-beams for the upper webs and a
ratchet-wheel with two engaging gear pinions, a vertical rod provided at both
extremities with forked ends, each of them embracing a turning die, the upper one of
said dies being arranged on the aforesaid bearing-lever and the inferior one being
adapted to turn round a small stud forming the end of one branch of a bent lever,
the other branch being connected by means of a rod to a reversing-lever arranged in
the middle before the power-looni, essentially as described and for the purpose
specified.
4. In a power-loom for weaving two or more webs at the same time, a picking-
shaft with two or more pickers adapted to slide on two or more horizontal rods and
connected together by means of a cross-piece provided with a slot to receive a little
stud fixed to the picking-shaft, essentially as set forth and for the purpose specified.
Dated this 25th day of March 1897.
