PROVISIONAL SPECIFICATION..
Improvements in Picking-band-fastenings for Looms.
I, ALBERT ABEGG of Zurich in the Republic of Switzerland, Manufacturer do
hereby declare the nature of this invention to be as follows:-
This invention has for its object to enable the full width of the band of a picker
to be utilized instead of as formerly using it edgewise which resulted in the bands
being very frequently torn or broken, and thereby reducing the consumption of
picking-bands which in a large weaving factory is a source of great expense.
In carrying the invention into practice a loop or yoke is applied to the picker so
that it will surround the part or bridge to which the band is usually attached and
the picking-band is passed between this part and the loop or yoke and is retained
in said position by a leather staple passed through the band or by an equivalent
fastening.
The loop or yoke may be applied to any form of picker including those of
ordinary construction, centre-top pickers and the pickers of drop-box-looms the
shape of the loop or yoke being varied to suit the different requirements.
The pickers when operated according to this invention are found to work smoother
and straighter than heretofore and consequently last longer and moreover fewer
oily spots are produced in the fabric worked in the looms.
Dated this 1st day of August 1891.

COMPLETE SPECIFICATION.
Improvements in Picking-band-fastenings for Looms.
1, ALBERT ABEGG of Zurich in the Republic of Switzerland, 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 has for its object to enable the full width of the band of a loom
picker to be.utilized instead of as formerly using it edgewise which resulted in the
bands being very frequently torn or broken, and thereby reducing the con-
sumption of picking-bands which in a large weaving factory is a source of
considerable expense.
The invention will be best understood by reference to the accompanying drawings
in which
Figs. 1, 2 and 3 are respectively a front elevation, a side elevation and a plan
showing the manner of applying my invention to an ordinary loom picker.
and
Fig. 4 is a central vertical section of Fig. 1.
Fig. 5 is a vertical section showing my invention applied to a centre top picker
Figs. 6 and 7 are respectively a plan and a vertical section showing my invention
applied to a picker of a drop-box loom.
Like letters indicate like parts throughout the drawings.
Referring to Figs. 1 to 4 A is the picker and B B' the usual guide rods.
A Fig. 4 is the bridge which in this form of picker as ordinarily constructed is
usually perforated for the attachment of the picking band but which need not be so
perforated according to this invention wherein the bridge A¹ is embraced by a
yoke C between the upper ends of which are one or more packing pieces C¹ which

are held in position by a staple D which passes through C and C' and has its ends
The yoke C and packing pieces C' virtually form a loop. The picking
band E is passed through the space which is left between the upper surface of the
bridge A and the under surface of the packing pieces C¹ and is retained in that
position by a leather or equivalent staple E' which is passed through the band.
It will now be obvious without further description how the whole width of the
band E is utilized.
My invention may be applied to any form of picker the only modification
necessary to adapt it to the different forms being a variation in the form of the
yoke C. To exemplify this I have besides illustrating the ordinary picker in
Figs. 1 to 4 shown two other pickers in Figs. 5, 6 and 7 and it is to be understood
that it is in no way intended to limit the invention to the application to these three
forms.
In the centre-top picker shown in Fig. 5 it is seen that the yoke C is made
smaller at its lower than its upper part this being rendered necessary so as to more
closely embrace the bridge A' which in this example is of less width than the
picker band E. Similarly and for the same reason in the arrangement shown in
Figs. 6 and 7 the yoke is smaller at its lower than upper part. These two forms
of pickers are too well known to require any special description, the reference
letters however which are shown in these figures and have not been specially
mentioned refer to parts corresponding to those similarly referred to in Figures 1
to 4.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. The combination with a loom picker of a yoke or loop substantially as and for
the purpose described.
2. The combination with a loom-picker of a yoke or loop such as C C¹ embracing
the bridge and picking band substantially as described and illustrated in the
accompanying drawings.
3. The combination with a loom-picker of a yoke or loop such as C C¹ embracing
the picking band E and a staple such as E' substantially as described and illustrated
in the accompanying drawings.
Dated this 31st day of August 1891.
ALBERT ABEGG.
