I THOMAS SINGLETON of Bank Top Works, Over Darwin in the county of
Lancaster, Machine Maker do hereby declare the nature of this Invention to be as
follows:-
In the fast and loose reed arrangement, I construct my knocking off apparatus,
so that on the shuttle failing to box, the loom immediately knocks off.
I employ a lever pivotted to the slay sword, one end of the lever rests on a
projection on the wing rod, and is retained in this position by a spring, the other
end of the lever extends to opposite the spring handle, on which is a projecting stud
which when the shuttle is doing its work properly, the lever passes over the stud,
but upon the shuttle failing to box the lever is moved, and its end depressed so that
it comes in contact with the stud on the spring handle, and stops the loom..
My improved brake consists of a blade spring partly encircling the brake wheel,
one end of the spring is attached to a fixed bracket, on the underside of the brake
wheel, the other is attached to a pivotted lever, which passes to the spring handle,
the spring passes through a piece of leather near its fixed end, and brings the leather
between it and the brake wheel, for regulating the brake lever, instead of a weight,
a regulating screwed rod is used, which passes through a slot in the brake lever, and
is adjusted by a nut on the underside of the lever, a notch prevents it moving; for
convenience in handling, the blade spring is narrowed on each side at the portion
which is towards the front of the loom, the spring in some case may be attached to
a fixed bracket at one end only, and the other end hang loose, and be put on by
contact with the end of the pivotted lever.

Agent for the Applicant.

In my fast and loose reed arrangement I construct my knocking off apparatus so
that on the shuttle failing to box, the loom immediately knocks off.
I employ a lever A, pivotted at B, to the sley sword, one end of the lever rests
on a projection C, on the wing rod D, (see Figs. 1 and 2), or it may rest on the
duckbill C (in Fig. 3), and in both cases is retained in position by a spring E, the
other end of the lever A extends to opposite the spring handle F, on which is a
projecting stud, when the shuttle is doing its work properly the lever passes over
the stud, but upon the shuttle failing to box, that is, when it is caught in the shed,
the reed case is acted upon in the usual way, raising the projection C, on the wing
rod, or raising the duck bill C, thereby moving the lever A, and depressing its end,
so that it comes in contact with the stud or projection on the spring handle F, and
stops the loom.
For regulating the reed case, I have a set screw N with lock nut attached to the
lever A; the point of the set screw N, rests against a plate P, on the sley bottom.
My improved brake consists of a metal blade G, partly encircling the brake
wheel H, one end of the blade is attached to a fixed bracket J (see Fig. 4) on the
underside of the brake wheel, the other is attached to a projection K, on the
pivotted lever L, which passes through or over a piece of flannel or felt M, near its
fixed end and for friction brings the flannel or felt M, between it and the brake
wheel; the flannel or felt also serves to clear the wheel of oil or grease. For
regulating the brake lever L, instead of a weight, a regulating screwed rod R may
be used, which passes through a slot in the brake lever, and is adjusted by a nut on
the underside of the lever, a notch prevents its moving; for convenience in
handling the brake wheel, I narrow the blade spring G on each side, (see Fig. 6) at
that portion which is towards the front of the loom

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1. In fast and loose reed or ordinary loose reed looms, the lever A for knocking
off in the manner and for the purposes shewn and described.
2. The shape of the metal blade G and the flannel or felt M, as and for the
purposes shewn and described,
