I JOHN CLAYTON MEWBURN of 55 and 56 Chancery Lane in the County of
Middlesex, Fellow of the Institute of Patent Agents, do hereby declare the nature
of this invention to be as follows:-
-
This invention relates to pickers for looms and consists of a special form and
arrangement which differs from the ordinary construction inasmuch as first the
strap or leather is completely separated from the spindle or rod on which the picker
is mounted, and secondly the strap is so placed or attached that its point of pull is
exactly in the centre line of the picker. The following advantages are thus
obtained-As the strap does not touch the spindle less oil is required for
lubricating the spindle and the diminution of the amount of oil prevents dust
forming with it a greasy mass which in the existing arrangement collects in the picker
and gets taken up by the strap and thrown upon the fabric, thereby producing
numerous spots, whereas with the improved picker the strap being entirely separated
from the spindle there is no risk of causing spots as just referred to; the picker
being pulled in its centre line travels more easily and lightly and hence the parts
of the loom are less strained, less repair is necessary, and less power; the picker
retains its shape and lasts longer, and therefore there is less loss through stoppages
or breakages; the strap having to support less strain breaks less often and there-
ore the losses due to such breakage are proportionately diminished.
In the improved arrangement or construction of picker the opening or eye for
he strap is formed at the upper part of the picker and so that the pull of the
trap shall be exactly in the axis or centre line of the picker. The part around
hich the loop of the strap passes is sufficiently thick to ensure the necessary
esistance. The strap does not extend far enough down to touch the spindle on
hich the picker is mounted.

I, JOHN CLAYTON MEWBURN of 55 and 56 Chancery Lane in the County of
Middlesex, Fellow of the Institute of Patent Agents do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement: --
This invention relates to pickers for looms and consists of a special form and
arrangement which differs from the ordinary construction inasmuch as first the
strap or leather is completely separated from the spindle or rod on which the
picker is mounted and secondly the strap is so placed or attached that its point of
pull is exactly in the centre line of the picker. The following advantages are thus

the spindle there is no risk of causing spots as just referred to; the picker
being pulled in its centre line travels more easily and lightly and hence the parts
of the loom are less strained, less repair is necessary and less power; the picker
retains its shape and lasts longer and therefore there is less loss through stoppages
or breakages; the strap having to support less strain breaks less often and there-
fore the losses due to such breakage are proportionately diminished.
In the improved arrangement or construction of picker an opening or eye for
the strap is formed at the upper part of the picker and so that the pull of the
strap shall be exactly in the axis or centre line of the picker. The part around
which the loop of the strap passes is sufficiently thick to ensure the necessary
resistance. The strap does not go far enough down to touch the spindle on which
the picker is mounted.
Figure 1 of the annexed drawings represents the preferred construction. It
will be seen on reference to this figure that the opening or eye for the strap L
is at the upper part of the picker and in such a position that the pull of the
strap is in the axis or centre line X of the picker. The loop of the strap passes
around the part T and the strap does not go down lower than the part F so that it
cannot touch the spindle M.
Figure 2 represents a modified and somewhat inferior form or construction in
which the part T is at the middle of the upper part of the picker.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me and in what manner the same is to be performed I
declare that what I claim in respect of pickers for looms is :-
The formation of an opening or eye for the strap at the upper part of the picker
in such manner that the strap cannot touch the spindle and that the pull of the
strap is in the centre line or axis of the picker, substantially as hereinbefore
described.
