Improved Means for Checking the Pickers of Looms for Weaving.
We, WILLIAM THOMPSON, of Park Bridge Mill, Blackburn, in the County of
Lancaster, Manufacturer, and JOIN MATHER of Park Bridge Mill aforesaid,
Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in appliances connected with the shuttle
picking apparatus of looms for weaving, the object being to provide improvements
constituting a combined preserver for the buffer, buffer strap, picker, and picker
strap, whereby these parts are subject to less wear and tear than heretofore. The
invention consists of a spring buffer, or a buffer the strap of which is connected by
a lever, or link and lever, to a spring which gradually eases the momentum of the
picker after it has expelled the shuttle from the box.
According to this invention, we employ a buffer as ordinary. To the buffer is
attached a buffer strap shorter than the ones generally in use, and the strap is
connected to one end of a bell-crank lever pivoted to the front of the shuttle box,
and the other end of the bell-crank lever is connected by a spiral spring to a fixed
point of the shuttle box. When the shuttle is expelled from the box, the picker
comes into contact with the buffer, the latter is moved along the spindle, the strap
moves the bell-crank lever and expands the spring, which gradually stops the
picker without much strain or jar on the picker, picker strap, buffer, or buffer strap.
When the buffer strap becomes worn after continued use, we cut off the worn
portion, and replace it with a metal link or bar, one end of which is attached to the
bell-crank lever; and the other end, by a short strap, to the buffer. The metal
link or bar may be substituted for the buffer strap in all cases if desired.

Improved Means for Checking the Pickers of Looms for Weaving.
We WILLIAM THOMPSON of Park Bridge Mill, Blackburn in the County of
Lancaster, Manufacturer, and JOHN MATHER, of Park Bridge Mill aforesaid,
Manager, 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 relates to improvements in appliances connected with the shuttle
picking apparatus of looms for weaving the object being to provide improved
apparatus constituting a combined preserver for the buffer, buffer strap, picker, and
picker strap whereby these parts are subject to less wear and tear than heretofore.
The invention consists of a spring buffer, or a buffer the strap of which is connected

page_text: by a lever, or link and lever, to a spring which gradually eases the momentum of
the picker after it has expelled the shuttle from the box.
Such being the nature and object of our said invention the following is a complete
description of same reference being had to the accompanying drawing which is a
view in elevation of a shuttle box having our improvements applied thereto.
According to this invention we employ a buffer 1 as ordinary. To the buffer 1
is attached a buffer strap 2 shorter than the ones generally in use, and the strap 2
is connected to one end of a cranked lever 3 pivoted on the ordinary buffer strap
bolt 4 to the front of the shuttle box 5 and the other and lower end of the cranked
lever 3 is connected by a spiral spring 6 to a fixed point or stud 7 on the shuttle
When the shuttle is expelled from the box the picker comes into contact
with the buffer 1 the latter is moved along the spindle 8, the strap 2 pulls the
upper end of the cranked lever 3 and expands the spring 6 which gradually stops
the picker without much strain or jar on the picker, picker strap, buffer, or buffer
.strap.
When the buffer strap 2 becomes worn after continued use we cut off the woru
portion and replace it with a metal link or bar 9. one end of which is attached
to the cranked lever 3 and the other end by the shorter strap 2 to the buffer 1 as
shewn. The metal link or bar 9 may be substituted for the longer buffer strap 2
in all cases if desired, and this we find generally preferable.
The lower end of the lever 3 is cranked at 10 and the cranked portion extends
under the shuttle box 5, and limits the amount of movement of the said lever and
holds the buffer 1 in the correct position on the spindle 8, that is about 2 inches
from the spindle stud.
The stud 7 is cast to the bracket 11 the latter being secured to the front of the
shuttle box 5 by bolt or bolts passing through the slot 12; by this means the
position of the stud 7 and consequent teusion on the spring 6, and resisting force
of the buffer 1 can readily be adjusted.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The general construction, arrangement, and combination of parts constituting
the improved picker checking apparatus, as and for the purpose herein described,
and substantially as illustrated by the annexed drawing.
2. The buffer 1 strap 2 cranked lever 3 and spring 6 with or without the link 9
all in combination as and for the purpose herein described and substantially as
illustrated by the annexed drawing.
