PROVISIONAL SPECIFICATION.
Improvements in Picking Bosses and Picking Plates in Looms for
Weaving.
We WILLIAM EDWARD WHITTAKER, of No. 4 Market Street, Church, in the
County of Lancaster, Blacksmith, and DENNIS BURY, of No. 172 New Lane Oswald-
twistle in the County aforesaid, Mechanic, do hereby declare the nature of this
invention to be as follows :-
Heretofore picking bosses have been cast in one piece, as have also picking plates,
and in cases of breakage, of one or the other, the picking shaft has had to be stripped,
to enable new bosses or new plates to be put on, which process entails, a considerable
loss of time, and money by reason of the loom being stopped, and the warps soiled.
According to this our invention we cast the picking boss in two pieces, one piece, or
segment being dovetailed, and the other piece having dovetailed recesses formed in it,
so that when one piece, or segment is placed in position on the picking shaft the other
portion may be locked or fastened to it by the dovetail, and recesses.
The picking
plate is also cast with a loose segment, so that when the larger portion is placed on
its shaft, and the loose segment put in position it forms a complete picking plate.
The segment we place at that portion of the plate, which is most apt to wear flat,
consequently if the segment is worn we can replace it by another, and the picking
plate will be again equal to new. It will thus be seen that the picking boss and
picking plate can be fastened in position on the picking shaft without passing over
either end of the same, and consequently without stripping the shaft.

page_text: We, WILLIAM EDWARD WHITTAKER of No. 4 Market Street, Church, in the County
of Lancaster, Blacksmith, and DENNIS BURY of No. 172, New Lane, Oswaldtwistle,
in the County aforesaid Mechanic, do hereby declare the nature of this invention
and in what manner the same to be performed, to be particularly described and
ascertained in and by the following statement :-
Heretofore picking bosses have been cast in one piece, as have also picking plates,
and in cases of breakage of one, or the other, the tappet shaft has had to be stripped
to enable new bosses, or new plates to be put on, which process entails a considerable
loss of time and money by reason of the loom being stopped and the warps soiled.
According to this our invention we cast the picking boss in two pieces one piece or
segment being dovetailed and the other piece having dovetailed recesses formed in
it, so that when one piece or segment is placed in position on the picking shaft, the
other portion may be locked or fastened to it by the dovetail and recesses.
The picking plate is also cast with a loose segment, so that when the larger portion
is placed on its shaft, and the loose segment put in position, it forms a complete picking
plate.
The segment we place at that portion of the plate which is most apt to wear flat,
consequently if the segment is worn we can replace it by another, and the picking
plate will be again equal to new. It will thus be seen that the picking boss and
picking plate can be fastened in position on the tappet shaft without passing over either
end of the same, and consequently without stripping the shaft.
Such being the nature and object of this our Invention, the following is a complete
description of same, reference being had to the accompanying drawings forming a
part of this specification in which
Fig. 1 is an end elevation of picking boss and picking plate (full size).
Fig. 2 is a similar view to Fig. 1, but the reverse or opposite side.
Fig. 3 is a side elevation of Fig. 1.
The remaining Figures on Sheet 2 are details drawn full size.
According to this our invention we cast the picking boss in two pieces, 1, 2, one
piece or segment 1 being dovetailed as at 3, and the other piece 2 having dovetailed
recesses 4 formed in it, so that when one piece or segment 1 is placed in position on
the tappet shaft 5, the other portion 2 may be locked or fastened to it by the dovetail 3
and recesses 4 and bolts and nuts 6-6. The picking plate 7 is also cast with a loose
segment 8, so that when the larger portion 7 is placed on its shaft 5, and the loose
segment 8 put in position and secured by nut and bolt 6 it forms a complete picking
plate.

page_text: The elongated nose 10 of the picking plate 7 can also be replaced when worn or
broken, being secured to the main portion of the plate 7 by nut and bolt 11 and
dovetailed recess 12.
The segment 8 we place at that portion of the plate 7, which is most apt to wear
flat, consequently if the segment 8 is worn we can replace it by another and the
picking plate 7 will be again equal to new.
It will thus be seen that the picking boss 1 and picking plate 7 can be fastened in
position on the picking shaft 5 without passing over either end of the same, and
consequently without stripping the shaft 5.
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;
The improved construction of picking bosses and picking plates as herein described
and illustrated by annexed drawings or any mere modification of same.
Dated this 3rd day of February 1888.
