PROVISIONAL SPECIFICATION.
Improvements appertaining to the Picking Motion of Circular Box
Looms.
CHRISTOPHER SHUTTLEWORTH 6, Cambridge Street, Colne, in the County of
Lancaster, Weaving Overlooker do hereby declare the nature of this invention
to be as follows:-
There are two pieces fastened together as a conumon door hinge, one of the
pieces is bolted to the frame work of the loom, while the other is held in contact
with the spindle, by means of a spiral spring, so that when the picker rebounds
after delivering the shuttle, it passes by the part in contact with the spindle and
is held there clear of the box.

Improvements appertaining to the Picking Motion of Oircular Box
Looms.
I, CHRISTOPHER SHUTTLEWORTH of 6, Cambridge Street, Colne, in the County of
Lancaster, Overlooker, 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 appartains to the picking motion of circular box looms, and
consists in an improved device for holding the picker when it has rebounded
after delivering the shuttle. It has hitherto been usual to employ a bow shaped
blade spring for this purpose, but these are liable to snap or break frequently,
and at unaxpected times, and are a source of some attention and repair in this
class of loom.
In the present invention, I fasten two pieces or plates together like a common
door hinge. One of these picces is much longer than the othar and is curved
bow shaped. The shorter piece is bolted to the framework of the loom, whilst
the longer pieco is acted upon by means of a spiral spring, which thereby holds
the bow shaped side in contact with the loom spindle. The picker, when it
rebounds after delivering the shuttle, passes between the bow-shaped hinge piece
and the loom spindle, and is firmly held thereby clear of the box until a change
has been effected, and a fresh box opening presented to the throw of the pick.
The accompanying drawing is a perspective view of my improved device for

page_text: retaining the picker after its robound, until a fresh box opening has been
presented in rotary box looms.
A and B are the hinge pieces hinged together as shewn at D. B the shorter
piece is bolted to the loom frame by the bolt C. A the longer piece extends
bow-shaped as shewn. The spiral spring E or other elastic medium is connected
by the hooks F or other means to the two hinge pieces A and B, and acts upon
the former in such a manner as to cause it to bear upon the loom spindle G when
the picker is absent. On its rebound, the picker H, after the delivery of the
shuttle to the opposite box, passes between the hinge piece A and the loom
spindle O, and is retained thereby until a fresh box opening has been presented.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. The improved device for retaining the picker after the throw of the pick
and until a fresh box opening has been presented in circular box looms,
substantially as described and illustrated in the accompanying drawing.
2. The hinge pieces A and B and spiral spring or other elastic medium E,
substantially as shewn and described for the purpose set forth.
