Improvements in Power Looms for Weaving Two or more Cloths
Simultaneously.
I, FELIX MEYER, of 78, Williamstreet, Aix-la-Chapelle, Rhenish Prussia,
Germany, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
The purpose of my present invention is to produce mechanically several webs at
the same time one above the other in a common power-loom, and that such webs
which can be independent from each other in all respects, that is referring to
the pattern, quality, colour, thickness and denaty of threads in warp and wefts,
so that all webs can be seen and are easy of control and of access during the
weaving.
I attain these objects by means of the mechanism illustrated in the accompanying
drawings in which,
Fig. 1 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 several reeds and races,
Figs 2 and 3 represent the front view and the cross-section of the lathe;
Fig 4 is the side view and
Fig. 5 the front view of the power-loom.
Similar letters refer to similar parts throughout the several views.
Several warp-beams are mounted at certain distances one above the other;
the warps wound off therefrom are operated nearly in the hitherto well known
manner
Each warp is guided through a separate mounting and through a separate
reed and is wound upon a separate piece-beam.
The piece-beams are operated independently of each other.
The shuttles are driven at the same time by means of a common picking-shaft,
and the lathe provided with several reeds beats at the same time all the wefts
shot in.
The warp-beams K, K1 are mounted at certain horizontal distances one above
the other and are provided with braking mechanisms like those used hitherto
in common power-looms with two beams only.
The mountings G G 1 arranged at the same height one behind the other, are
essentially equal to those used hitherto
The number of the shafts as well as that of the heddles arranged thereon
can be at will for each mounting and can be changed independently from the
other mountings.
The intersections need not correspond at all
The mails are not arranged, like hitherto, in the middle of the heddles, but
at different height for each shaft necessary for each warp.
The distance of the shafts from each other is large enough in order that
DQJ1

from crossing each other.
In my new power-loom there are consequently arranged several self-depen-
dent mountings independent in all respects from each other in order to be able
to change at will the density of warps as well as the intersections and the
number of shafts
Several reeds R R1 are mounted one above the other in a common lathe.
Before each reed there is arranged a race. The reeds are easy of change; their
density corresponds with that of the corresponding warp
The breast-beams are constructed in a different manner.
The lower breast-beam B 18 constructed and mounted in exactly the same
manner like that in the common power-loom used hitherto.
The upper breast-beams consist cach of two small rollers or shafts B1 W
mounted one above the other, between which rollers the cloth T1 is guided to
the cloth-beam. By means of adjusting screws the rollers can approach one
to another more or less collesponding to the thickness of the cloth.
The breast-beams are just as high mounted as the corresponding back-rails
and reeds
The lower piece-beam 18 mounted in the hitherto well-known manner.
The upper cloth-beams are mounted each in two levers H that can be turned
round a fixed centre situated in the middle between the geometrical axis of the
two breast-beam-1ollers
The free ends of the levers H are connected by means of moveable rods 8
to a reversing mechanism, arranged before the power-loom and by means of
which the upper cloth-beams can be mounted or descended at will during the
weaving, without altering the tension of the upper cloth.
The construction of the mechaniam for displacing the upper cloth beams
is best to be seen from Fig 5 which shows that mechanism in front-view with
regard to the power-loom.
On the foot of the power-loom there is arranged a toothed segment Z on which
the reversing lever U provided with a handle g and a spring-acted look-bolt &
can be turned to the right or to the left at will and secured in any position.
Two rods 1 pivoted on the reversing-lever U at equal distances from its
pivot, are connected each to a bent-lever W, W₁, the other branch of which bent-
fever is connected to vertical rods S S 1, the upper extremities of which are pivoted
to the free ends of the levers H bearing the upper cloth-beams T1
In order to turn the levers H and consequently to displace the cloth-beams,
I press the handle g containing the spring, by consequence whereof the lock-
bolts of the reversing lever U disengages from the toothed segment and I can
turn the reversing lever to the right or to the left at will. By consequence
thereof the levers H are turned by means of the rods t t1 and of the bent-
levers W W 1 and the cloth-beams mounted in the levers H are msen or lowered.
The mechanism for winding up the cloth is constructed for the under cloth-
beam exactly like the mechanism in the well-known power-loom, that is with
ratchet-wheel and click.
For the upper cloth-beams this mechanism 18 essentially the same too, but
the click engages the ratchet wheel not from above, but from below and is large
enough as to engage the ratchet wheel whatever position the cloth-beam may
take
To the axle of the cloth-beam the long click is connected by means of a little
spring.
The shuttle-boxes are constructed as in the common power-looms but are
relatively higher and contain more shuttles To the number of shuttles and
corresponding pickers answers the number of the guide-bars for the latter. The
picking-shaft engages not immediately the pickers, but it engages a cross-piece
that connects the pickers one with another The shaft operates the cross-piece
and consequently all pickers connected to the cross-piece.

page_text: 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:
1
New and useful power-loom for producing at the same time several webs one
above the other and which webs need not be equal neither with regard to inter-
section, nor to warp nor to wefts, in which power-loom different warps or
guided through mountings and reeds, independent from each other, to cloth-
beams that may be displaced so that, during the weaving, all webs can be seen
and are easy of access
