COMPLETE SPECIFICATION.
An Improved Ribbon Loom with Multiple Driving Gear.
1, JEAN GÜSKEN, of Dülken, in the German Empire, Manufacturer, do hereby
declare the nature of this invention and the manner in which it is to be per-
formed to be particularly described and ascertained in and by the following
statement;
The present invention refers to an improved ribbon-loom with multiple driving
gear which is specially adapted for the manufacture of velvet ribbons. The gener-
ally known ribbon looms are so arranged that a plurality of ribbons, one aside the
other, can be woven simultaneously with one loom; for which purpose a common
driving axle is fitted with the necessary number of shuttles and their accessories.
Up to 32 ribbons have thus been produced simultaneously the latter requiring the
attendance of one man only. The arrangement just described suffers from the
great disadvantage, that when an interruption occurred in the manufacture, as
tor instance the breaking of a thread, the whole number of shuttles had to be
stopped. It is obvious that this inconvenience is increased by a larger number
of shuttles and it is this reason which prevents the multiplication of the shuttles
beyond a certain number as, any irregularity happening, the entire number of
shuttles will have to be stopped.
The present invention has for its purpose to obviate the drawback described.
The shuttles are divided into two groups, each of which is provided with a special
driving gear. In consequence hereof, should a disturbance in the action of the
loom occur, it will only be necessary to stop one group while the other continues
working. This arrangement further permits the number of the shuttles of a
ribbon-loom to be greatly increased (up to 50) the whole number of shuttles re-
quiring the attendance of one man only. Even with such a large number of
shuttles the loom will still be easily manageable.
By way of example I have illustrated one mode of carrying out the invention
in the accompanying drawing which shows a front elevation of the loom. The
improved loom consists of two symmetrical parts, each of which presents the
arrangement of an ordinary single loom. On either side of the frame a bracket a
is arranged which serves for supporting the eccentric shaft b. This shaft b is
driven from the belt by means of any suitable transmitting gear. The treadles
for actuating the shuttles of the batten receive their motion from the eccentric
shaft b.
It is advantageous for a loom constructed and arranged as described above to
provide means for throwing in and out of gear with the driving mechanism either
of the two groups of shuttles constituting the improved loom from the same place
without necessitating the attendant to actuate the hand levers, described further
on themselves. To carry out this purpose either group of shuttles is provided
with a hand lever d, actuating the mechanism for throwing out of gear with the
driving mechanism the respective group of shuttles. A helt shifter, for instance,
may be actuated by the hand levers d, which belt-shifter shifts the driving belt c
on to a loose pulley, thus stopping the action of the respective group of shuttles.

page_text: A rod e is pivoted to each of the two hand levers d and extends, being loosely
supported in suitable bearings in the weaving-loom frame, horizontally from one
group of shuttles to the other respectively. The attendant, supposing him to be
standing at the left hand group of shuttles, is thus enabled to throw out of gear
with the driving mechanism the left hand group by actuating the respective hand
lever d, but he may likewise throw out of gear with the driving mechanism the
right hand group of shuttles by pulling the respective rod e in connection with
the hand lever d of the right hand group of shuttles. By pulling the handle d
and the rode of the hand lever of the second group at the same time, both groups
of shuttles can of course be stopped simultaneously.
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. An improved ribbon-loom specially adapted for the production of velvet
ribbons having its operating organs arranged in two groups either of which groups
comprises half the total number of shuttles of the loom and is actuated by an
independent driving gear, substantially as set forth.
2. In combination with a ribbon loom as described a coupling mechanism which
may be actuated from any part of the loom, consisting in a hand lever for each
group for actuating the coupling gear in combination with a connecting rod lead-
ing to the second group of the loom, substantially as set forth.
