PROVISIONAL SPECIFICATION.
Picking Relieving Attachment for Power Looms.
WILLIAM GIBB SIMPSON 108 Magdala Terrace, Galashiels, Power Loom Tuner, do
hereby declare the nature of this invention to be as follows:-
The invention consists of an attachment to a power loom which relieves the
pressure from the shuttle box swell, when the loom is in the act of picking. This is
accomplished by attaching a specially shaped adjustable lever to the stop rod, so that
the crank arm will operate on this lever at each revolution of the crank, and thus
actuate the stop rod and shuttle box swell at the proper time.
By this means the tear and wear on all the varied parts of the picking motion is
very much reduced, and the power required in picking is much less.
Dated this the 7th day of October 1896.
WILLIAM G. SIMPSON.
WILLIAM GIBB SIMPSON 108 Magdala Terrace Galashiels N.B. Power Loom
Tuner 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 consists of an attachment to a power loom, which relieves the
pressure from the swell of the shuttle box, when the loom is in the act of picking,
but allows the pressure to be maintained on the swell, when the shuttle is entering
the box.
In Fig. I the shuttle is in the act of entering the box, and A shows the swell of the
shuttle box. When the shuttle F, is entering the box, the finger G of the stop-rod C
is pressing against the swell A. This pressure would be maintained throughout
the act of picking, viz.: throughout the time when the shuttle is leaving the box, if
it were not relieved. My invention relates to an attachment B for relieving the
pressure of the finger G upon the swell A.
B is a lever or bracket, adjustable on the stop-rod C, and when adjusted is fixed by
a set screw to the stop-rod. This stop-rod acts as the fulcrum of the lever or
bracket B.
In Fig. I, where the shuttle is entering the box, the position of the crank E is
such, that the crank arm, or connecting arm D does not press on the attachment B.
In Fig. II, where the shuttle is leaving the box, the position of the crank E is such,
that the crank arm or connecting arm D, presses on the attachment B. This pressure

page_text: causes the stop-rod C. to revolve slightly, and the finger G of the stop-rod C. is drawn
back from the swell A. This is repeated at each revolution of the crank E.
The lever or bracket B, may be made in one piece, but I make it preferably with a
flat spring, at the end which comes in contact with crank arm or connecting arm D.
This spring gives a more yielding motion than the other. In Figs. I and II the
lever B is shown shortened, so as to admit of the flat spring being joined to 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 :-
(1) The use and employment of an attachment which relieves the pressure on the
shuttle box swell in the manner as herein described and illustrated.
(2) The use and employment of an attachment in one piece, or joined, in the
nanner and for the purposes as herein described, and. illustrated..
(3) The use and employment of an attachment, so that the pressure is maintained
on the swell, when the shuttle is entering the box, in the manner as herein described
and illustrated.
