IMPROVEMENTS IN THE PICKING MOTION OF LOOMS FOR WEAVING
Year: 1884

page_text: I, ARTHUR SOWDEN of the firm of David Sowden & Sons, Thornton Road
Bradford in the County of York, Machine Maker do hereby declare the nature of
my invention for IMPROVEMENTS IN THE PICKING MOTION OF LOOMS FOR WEAVING
to be as follows:-
This invention has for its object the mounting of the picking shafts of looms for
weaving in such a manner, that the springing or vibration of the shafts is reduced,
and the liability of the shaft footsteps or top journals moving or sliding away from
the true position is minimised which I accomplish in the following manner:-
I form the picking shaft with a collar thereon, and secure an additional
adjustable journal immediately above the tappet cone, which supports the shaft
when the ordinary tappet strikes the picking cone, the collar on the shaft preventing
the same rising when picking. The footstep and top journal of each picking shaft
I further secure by attaching additional brackets to the loom end, and passing
through them screws which also pass through paps on the journal and footstep
brackets;
the screws being provided with lock nuts to prevent them unscrewing
when tightened with the brackets in true position.

I, ARTHUR SOWDEN of the firm of David Sowden and Sons, Thornton Road,
Bradford, in the County of York, Machine Maker, do hereby declare the nature of
my invention for IMPROVEMENTS IN THE PICKING MOTION OF LOOMS FOR WEAVING,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has for its object the mounting of the picking shafts of looms for
weaving in such a manner, that the springing or vibration of the shafts is reduced,
and the liability of the shaft footsteps and the top journals moving or sliding away
from the true position is minimised; and consists in forming the picking shaft
with a collar thereon, and securing an additional journal immediately above the
tappet cone, by which the shaft is supported: the footsteps and top journal
brackets, I further secure by attaching additional brackets to the loom end; and
pass through them screws, which also pass through snugs on the top journal
and footstep brackets; the screws being provided with lock nuts to prevent them
unscrewing.

In the accompanying drawings Fig 1 represents an elevation shewing a portion
of a loom end frame with my invention added thereto. Fig 2 illustrates another
kind of bracket for supporting the picking shaft. The remainder of the figures
are details of my improvement drawn to an enlarged scale; in all the figures
similar letters indicate similar parts.
The loom end A is of the ordinary construction, and secured thereto are the top
bracket B and footstep C; and immediately above the slotted part of the picking
shaft D where the cone stud is secured; I attach to the loom end an additional
journal E, which is recessed for a collar on shaft D, and supports the said shaft
when the ordinary tappet strikes, the picking cone; the collar preventing the shaft
rising when picking.
The top journal bracket B, and footstep C, are bolted to the loom end, and are
further secured by attaching additional brackets F, F, to the loom end by passing
through them screws G, which also pass through "snugs" cast on the top journal
bracket B, and footsteps C. These screws are provided with nuts which clip each
side of the "snugs," and with a nut on one side of each of the brackets F, F; by
screwing the latter tight against the brackets, the screws are rigid; and on
tightening the other two nuts, the top journal bracket B, or footstep C, as the case
may be, is attached to the respective bracket F, thereby further securing the
mountings B and C, by which the picking shaft D is supported. Should it be
desired, the screws G may be extended beyond the shaft mountings, and nuts
placed thereon to clip similar brackets F on the opposite side at X, and thus further
provide against the possibility of the mountings B, and C, moving out of their true
position.
Fig. 2 shews a different kind of bracket for staying the picking shaft: according
to this method, I secure a saddle casting H to the loom end, and attach thereto
bracket J. prepared for the reception of a collar on the picking shaft D. This
bracket J and also the bracket E, are prepared at the soles with V grooves as

page_text: shewn by detail Fig 3, by which the brackets when bolted are held more rigid in
the required position.
The picking shaft D I make in two parts, and form the end of each portion"
square, upon which I secure a coupling K having a square hole through, thereby
connecting the two parts, either of which may be replaced should one through any
cause require it.
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
The staying of picking shafts by securing an additional journal immediately
above the cone stud eye, substantially in the manner described and as illustrated
by the accompanying drawings.
The staying of the footstep and top journal brackets by the screws. G, sub-
stantially in the manner described and as illustrated by the accompanying
drawings.
