Improvements in Means for Checking Shuttles in Looms for Weaving.
We, XAVIER, PRINCE DRUCKI-LUBECKI, of 46, Nowy-Swiat, Warsaw, and ADOLP
REINERT, of 13, Glowna, Lodz, Master Weaver, both in the Empire of Russia,
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:
This invention relates to shuttle catchers which may be applied to any loom
without cutting out parts of the wood work, and which, besides being very simple,
is adapted to be adjusted to the variable force of the shuttle.
This invention consists essentially in a lever situated behind the picker, which
is connected with a curved and slotted eccentric piece, which is connected to an
adjustable spring. The curved piece or eccentric is of such form and the spring
is regulated so that the lever situated in the shuttle box offers a resistance of a
predetermined amount when the shuttle runs in and adjustment by the picker
takes place, just sufficient to overcome the force of the shuttle running in.
During this action, the lever connected with the picker, and the spring and other
working parts return into their original position, owing to the peculiar form of
the curved piece or eccentic, only when the shuttle is shot to the other end of
the box.
In order that this invention may be the better understood, I now proceed to
describe the same reference being had to the accompany drawings and to the
letters and figures marked thereon.
Figure 1 is a rear view of one side of the shuttle box.
Figure 2 is a plan thereof,
Figure 3 corresponds with Figure 1, the moving parts occupying a different
position.
Figure 4 is a sectional view on the line x-x of Figure 2.
The lever or arm a is fixed to an axle b, which can be easily rotated in a bear-
ing. To the same axle is fixed in any desired position a curved or eccentric
piece c by means of a screw b¹. In the construction as illustrated the piece c has

piece el, Figure 4, provided at its lower end with a hook e². A spiral spring f
is suspended from this hook, the other end of the spring being connected with
the hooked end g² of a bent pin g, the latter is adjustable as to height by means
of a screw h, whereby the tension of the spring f may be exactly regulated.
When the shuttle k runs into the shuttle box, it presses the picker i against a

designed in such a manner, and its effect corresponds to the action of the exactly
adjusted spring f so that the shuttle is braked gradually, and the various marts
are maintained in the positions shown in Figure 3: the spring, f being unable to
exert sufficient force to return the parts into their original position shown in
Figure 1. This can only be done when the shuttle k is thrown to the other side
of the loom. Then the resistance to be overcome by the spring f is less and
the parts return to the position in which the are ready to operate again.

The advantageous effect of this novel shuttle catcher is increased, by the
lever a being adapted to yield towards the left after the various parts have occu-
pied the positions shown in Figure 3, the piece e rotating around the axle b and
carrying with it the roller e situated at the utmost right hand end of the curved
slot. In consequence the whole device is very elastic and the parts are greatly
protected against wear and tear.
If one or other part should be worn out by the working of the device, a new
part can be substituted therefor with ease and without considerable cost.
Each side is provided with the same arrangement, but the parts correspond as
to position and shape to the side of the loom to which they are applied.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed. I declare that what
I claim is:
1st. A shuttle catcher having a lever a arranged in the shuttle path on each
side of the loom, connected with an eccentric or curved piece c, and adapted to
be turned by the picker i when the shuttle k runs in, in order to stress a spring
which is regulated so that it can return the working parts into their original
position only when the shuttle is shot from the box.
2nd. A mode of carrying out the shuttle catcher claimed in Claim 1, in which
the curved piece c has a curved slot adapted to guide a roller e connected
to an adjustable pin g by a spring f, the curved piece being adjustable as to
its position after loosening a screw b¹, substantially as described.
Dated this 15th day of July 1898.
