PROVISIONAL SPECIFICATION.
Improved Arrangement for Protecting Throw-straps and Pickers of
Machine-weaving Looms.
I, FRANZ WANEČEK, of Rumburg, Austrian Empire, Weaver, do hereby declare
the nature of this invention to be as follows:-
My invention has for its object to lessen the wear and tear on throw straps and
pickers of machine weaving looms, and the manner in which I prefer to carry my
invention into effect is shewn in the accompanying drawings.
To the cross beam A of the loom is affixed an arm a preferably of iron, which
arm however is not always straight as shewn in the drawing but may be and is some-
times bent in accordance with the shape and construction of loom, and so as not to
interfere with other working parts. It is affixed so that it can be moved slightly
both sideways and up and downwards, for which purpose slits & and a are made in
the cross beam and the arm respectively, or in metal fittings attached, and the fastening
is done by means of a set screw 2.
e,
Through arm a passes a loose spindle, on which is formed an iron button and
between that and the face of arm a is an india rubber ring f, which is drawn over
the spindle, and a double protection leather d. Furthermore a heavy strap c is laid
loosely round the head button e being pierced by the piston b.
The contrivance works in the following manner.
The arm a is adjusted to such a position that it meets the picking stick B at a
point where sufficient force has already been communicated to the picker D in
order to drive the shuttle through the leash. If the apparatus were not thus
fixed, then the picking stick B would throw unnecessarily far and only stop on being
arrested by the strap c, which in consequence suffers great wear and tear.
The stopper arrangement is contrived in such a manner that the picking stick is
stopped softly, striking against the bow of leather-strap c and then driving the piston b
back, thus compressing indiarubber ring f, which afterwards expands, again bringing
the piston b forward.

I, FRANZ WANĚČEK, of Rumberg, Austrian Empire Weaver, do hereby declare
the nature of the said invention and the manner in which the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
My invention has for its object to lessen the wear and tear on throw straps and
pickers of machine weaving looms, and the manner in which I prefer to carry my
invention into effect is shown in the drawings filed with the present Specification.
To the cross beam A of the loom is affixed on arm a, preferably of iron which
arm, however, is not always straight, as shown in the drawing, but may be and is
sometimes bent, in accordance with the shape and construction of loom, and so as
not to interfere with other working parts. It is affixed so that it can be moved slightly
both sideways, and up and downwards, for which purpose slits x and x¹ are made

fastening is done by means of a set screw z.
Through arm a passes a loose spindle b, on which is an iron button e, and between
that and the face of arm a is an india-rubber ring f, which is drawn. over the
spindle, and a double protection leather d, and furthermore, a heavy strap is laid
loosely round the head button e, being pierced by the piston b.
The contrivance works in the following manner :-
The arm a is adjusted to such a position that it meets the picker stick B at a

the shuttle through the leash. If the apparatus were not thus fixed, then the picking
stick B would throw unnecessarily far, and only stop on being arrested by the strap c,
which in consequence suffers great wear and tear.
The stopper arrangement is contrived in such a manner that the picking stick is
stopped softly, striking against the bow of leather strap c, and then driving the
piston back, thus compressing india rubber ring f, which afterwards expands again
bringing the piston / forward.
Having now particularly described and ascertained the nature of the said
invention and the manner in which the same is to be performed, I hereby declare
that I claim as my invention
The improved arrangements for protecting throw straps and pickers of machine
weaving looms, substantially as hereinbefore set forth and described and illustrated by
the drawings filed.
