PROVISIONAL SPECIFICATION.
Improvements in or connected with the Pickers and Picking Bands
of Looms.
I, JOHN RAWSTRON, of Waterfoot, in the County of Lancaster, Currier and
Strap Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention is designed with the object of providing an attachment between
the pickers by which the shuttles are operated and the bands or straps by which
they are connected to the picking sticks and through which motion is conveyed to
the picker which will be easy of adjustment and less liable to wear and tear than
the present method of attachment.
It consists essentially in the combination with a picker and picker band of a bolt
with suitable formed head which is passed through the top of the picker and end of
the band and an elastic cushion of leather rubber or other material placed
between the band and the washer and nut of the bolt to prevent the cutting or
tearing of the strap.
In carrying out the invention the picker may be of any ordinary form. Through
the slot in the head or top of the picker I insert a bolt preferably with a head of
T shape which can be inserted from above the head being of a size to fit through
the slot. It is also flanged or turned up at the edges so that when turned round
into position at right angles to the slot the flanged edges will embrace the side of
the picker and be thereby prevented moving out of position. A hole is formed in
the end of the picking band through which the end of the bolt is passed. On the
top of the band interposed between it and the washer and nut of the bolt I place
an elastic cushion of leather rubber or other material preferably a piece of
leather doubled in two to present a rounded edge to the band when doubled or
turned back over it. The picker is thus securely attached to the band the elastic
cushion preventing vibration between the two and also the band from coming in
contact with the hard surface of the metal washer.
By this invention I am enabled to affix or attach the band to the picker without
having to remove it from the spindle, the picker is actuated square on the spindle
with less friction and the wear and tear in both pickers and bands is considerably
less than has hitherto been the case.

COMPLETE SPECIFICATION.
Improvements in or connected with the Pickers and Picking Bands
of Looms.
I, JOHN RAWSTRON, of Waterfoot, in the County of Lancaster, Currier and
Strap Manufacturer, 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 is designed with the object of providing an attachment between
the pickers by which the shuttles are operated and the bands or straps by which
they are connected to the picking sticks and through which motion is conveyed to
the picker which will be easy of adjustment and less liable to wear and tear than
the present method of attachment.

page_text: It consists essentially in the combination with a-picker and picker band of a bolt
with T-shaped head which is passed through the slot in the top of the picker and
end of the band and an elastic cushion of leather rubber or other mater al placed
between the band and the washer and nut of the bolt to prevent the cutting or
tearing of the strap.
The invention will be fully described with reference to the accompanying
drawings.
Fig. 1. Perspective view of picker showing my invention applied thereto for
securing the picker band.
Fig. 2. Perspective view of bolt with nut and washer.
Fig. 3. Ditto of plate or washer placed between the bolt head and picker.
The picker A is of any ordinary form or construction as is also the picker
spindle B upon which it slides and the picker band or strap C.
Through the slot a in the head or top of the picker I insert from above a bolt D
the head being of a size to fit through the slot. The bolt D is provided with a
Thead which on being inserted through the slot a in the picker head can be turned
to the position shown to prevent it passing back again the head of the bolt D is also
flanged or turned up at the edges d so that when turned round into position at right
angles to the slot e the flanged edges will embrace the side of the picker and be
thereby prevented moving out of position. Between the head d of the bolt D and
the picker I prefer to place a metallic plate or washer such as E to prevent the
bolt head cutting into the picker.
In the end of the picker band C a hole is cut or punched to receive the end of
the bolt D.
On the top of the picker band C interposed between it and the nut of the bolt D
1. place an elastic cushion F of leather, rubber or other material preferably a
piece of leather doubled in two as shown to present a rounded edge to the band
when doubled or turned back over it. The picker is thus securely attached to the
band the elastic cushion preventing vibration between the two and also the band
from-coming in contact with the hard surface of the metal washer.
.
The nut of the bolt D may be of any usual or ordinary shape but I prefer to
make it of the shape shown in the drawings, so that it may be screwed or turned
tight by means of a spindle inserted in it and without the use of a screw key.
By this invention I am enabled to affix or attach the band to the picker without
having to remove it from the spindle, the picker is actuated square on the spindle
with less friction and the wear and tear in both pickers and bands is considerably
less than has hitherto been the case.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
The combination with the pickers and picker bands of looms of a T headed bolt
passed through the head of the picker and an elastic cushion inserted between the
picker band and nut on bolt with or without a metallic plate between the head of
the bolt and the picker substantially as described and shown.
