Improvements in or relating to Pickers for Looms.
I, Samuel FielDEN, of Stansfield Cottage, Todmorden in the County of York,
Cotton Spinner, 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 :-
My invention relates to pickers used in looms for weaving and consists broadly
stated in the arrangement use and application as a means for attaching the picking
band or strap to the picker of a pivotel link or swivel piece detachably connected to
the picker at a point below the spindle holes and preferably near the centre of the
picker so that when in operation the said link or swivel connection always adjusts
itself to the proper angle whereby a straight or approximately straight pull is
obtained.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Similar letters refer to similar parts throughout the several views.
Referring first to the picker illustrated by Figures 1 and 2 and the detail view
Figure 3-a designates a hide picker which may be made with an open top as shown
or may be of other well known constructions.
I prefer to hold the hide portions of the picker together by a staple or cramp bas
shown but this is not essential and forms no part of my present invention.
The link or swivel connection in this case consists of a single piece of metal c
formed preferably with two small bosses c¹ each of which is threaded to receive a
screw by which the link is secured to the picker as shown in Figs. 1 and 2. An
ordinary screw may be employed but I prefer to use a differential screw with the end
which is of reduced diameter of a coarser pitch than that near the head and the
bosses care of course tapped to correspond. The picking band or strap is secured
to the link e in any convenient manner and it will be readily understood that when
the hide portion of the picker has become worn and practically worthless the metal
link will be almost as good as new so that by removing the screw d the link e can be
readily detached from the worn picker and similarly attached to a new hide picker.
Referring now to the picker illustrated by Figures 4 to 6 and the detail views
Figures 7 and 7 the link in this case is made in two parts c³ ³, the part c² is bent
into the form shown best in Figures 6 and 7 and is passed through a hole formed to
receive it in the central portion of the body of the picker and the part e is then
screwed on to the threaded end of the part o².
The shanks or curved ends of the parts c² 3, are passed through a hole in the
picking band e which thus secures the pieces c c³, together and is itself connected to
the picker.
Figure 8 shows another swivel connection made in two parts of c shown detached
in Figures 9 and 10 those portions of the parts c c which pass through the body of
the picker are preferably half round so that when placed side by side as shown in
Figure 8 they form a circular pivot for the link to swivel upon.
The free ends of the parts are screwed and are secured together by a wing
nut which also secures the picking band e in position as shown. To prevent the
nut working loose a lock nut or other device may be employed.
Figure 11 shows a swivel connection also made in two parts ccf the part c
having a right hand thread and the part e a left hand thread and the two care
screwed into a prepared tube which passes through a hole in the central portion of
the body of the picker. The ends of the shanks may be curved as shown or may be
straight and threaded and secured together by a nut as in Figure 8.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is
1. The arrangement use and application as a means for connecting a picking
hand or strap to a picker of a pivoted link or swivel piece detachably connected to
the body of a hide picker for the purposes, specified.
2. The combination with a picker, of a pivoted metal link or equivalent swivel
piece substantially as and for the purposes specified.
3. The several constructions of metal links or swivel connecting pieces substan-
tially as and for the purposes herein described and as illustrated by the Drawings
annexed.
