I, ERNEST PETTERSSON, of Norrkopings Bomullsvafveri Aktie Bolag, Norrköping,
in the Kingdom of Sweden, Manager do hereby declare the nature of my invention
to be as
for "IMPROVEMENTS IN PICKER-STICKS FOR LOOMS FOR WEAVING
follows:-
23
The object of my invention is to produce a picker-stick which will prevent the
great wear and tear hitherto experienced in picker-sticks and straps, and consists
in forming the head or free end of the picker-stick to which the strap is generally
fastened, with a spiral recess at such angles as to suit the direction in which the
strap is working the picker in order that the great strain to which the strap when
picking, is subject, will be divided uniformly on both borders or the edges of the
strap, instead of only on one as heretofore has been the case and the result of great
wear and tear in both picker straps and sticks.
The inner end of this spiral recess is reduced to the normal, and the extreme end
shaped off to an increased thickness or diameter of the picker stick.
Over the extreme portion of the spiral recess a wire is arranged to prevent the
strap from leaving the recess when picking.
The portion behind the recess is provided with pegs on which the picker strap is
fastened having a suitable number of holes formed therein and being wound once
or twice around it, which means of fastening permits of an easy adjustment of the
strap when the length of the same requires altering, on account of the strap end,
to which the picker is connected, becoming worn.
Improvements in Picker Sticks for Looms for Weaving.
I, ERNEST PETTERSSON, of Norrkopings Bomullsvafveri Aktie Bolag, Norrkoping,
in the Kingdom of Sweden, 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 :-
The object of my invention is to produce a picker stick which will prevent the
great wear and tear hitherto experienced in picker sticks and straps, & consists in

page_text: forming the head or free end of the picker stick, to which the strap is generally
fastened, with a spiral recess at such angles as to suit the direction in which the
strap is working the picker, in order that the great strain to which the strap, when
picking, is subject, will be divided uniformly on both borders or the edges of the
strap, instead of only on one as heretofore has been the case, and the result of great
wear and tear in both picker straps and sticks.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 gives a general side view of the picker stick and strap as applied to
a loom.
Fig. 2 is a side view of the picker stick end without the strap. A is the picker
stick, B the picker strap, C the slay, and shuttle box, D, the picker stick shaft,
and E the picker.
In carrying out my invention I form the head or free end of the picker stick A
with a spiral recess a, the inner end of which is reduced to the normal, & the
extreme end shaped off to an increased thickness or diameter of the picker stick A.
Over the extreme portion of the spiral recess a a wire b is arranged to prevent the
strap B from leaving the recess a when picking.
The portion behind the recess a is provided with pegs c-on which the picker
strap B is fastened, having a suitable number of holes formed therein and being
wound once or twice around the picker stick A, which means of fastening permits
of an easy adjustment of the strap B, when the length of the same requires altering,
on account of the strap end to which the picker E is connected, becoming worn.
This picker stick may be made of wood or any other suitable material or combination
of materials or substances.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim, is
The peculiar form of the free end or head of the picker stick, which permits the
picker strap to be wound and to bear around the picker stick, evenly and flatly at
such an angle so as to suit the direction in which the strap is working, to ensure
a uniform strain or pull being exerted on both borders or edges of the picker strap,
for the purpose specified substantially as described & illustrated in the accompanying
drawing.
