Complete Specification Left, 13th May, 1890-Accepted, 14th June, 1890
PROVISIONAL SPECIFICATION.
An Improved Fast and Loose Reed Motion Employed in Looms for
Weaving.
We, JOHN WILLIAM SHORROCK of the firm of J. & R. Shorrock of Bolton Road
Foundry, Loom Makers, and JAMES KENYON HACKING of 10 Belgravia Terrace,
Foreman Slay Maker, both of Darwen in the County of Lancaster, do hereby declare
the nature of our said invention to be as follows:-
This invention relates to an improved fast and loose reed motion employed in
looms for weaving and consists in simple and efficient means whereby the reed is
locked when the shuttle is in the box, and released when passing through the
"shed." The stop rod is fitted with fingers of any convenient or suitable descrip-
tion. On each shuttle spindle is loosely mounted a hooked projection and a
spring or its equivalent. The hooked projections are held in position by guards
mounted on the back board of the "slay." The hooked projections are operated
by each stroke of the shuttle, by which the former are moved on the shuttle spindles
into position to hold the stop rod fingers and lock the reed when the shuttle is
in the box at each end of the "slay." Instantly the shuttle leaves the shuttle box
at each end of the "slay" the hooked projections assume their normal position
by the action of the springs or their equivalents and thus releases the stop rod fingers
and reed.

page_text: DESCRIPTION OF DRAWINGS.
Fig. 1 is a part front elevation of the shuttle-box end of the "slay" of a loom with
our invention applied.
Fig. 2 is a plan of sane showing position of our improvement when reed is loose
and shuttle is passing through the "shed."
Fig. 3 is a sectional elevation through line A' B' in Fig. 1, and
Fig. 4 is a part plan of Fig. 1. showing how reed is locked when shuttle is
in box.
.
A is the shuttle-box disposed on each end of the "slay" of the loom; B the shuttle
spindle the back-board of the shuttle-box, and D is the stop rod secured to the
underside of the "slay" in the usual manner, provided with fingers and other
appliances for operating on the reed. On the shuttle spindle B is mounted loosely
the hooked projection E extending through the back-board of the shuttle-box. The
hooked projection E is held in position in the back-board C by the guard G secured
by the screws H. The hooked projection E is coupled to one end of the spring I, the
other end of the latter being attached to the back-board C of the shuttle-box by the
hook J. The hooked projection E is operated by the picker mounted on the shuttle
spindle Beach time it is struck by the shuttle when entering the shuttle-box. When
the picker is struck by the shuttle the hooked projection E is moved outwardly into
the position shown in Fig. 4, which slides the same over the lever or finger K
mounted on the stop rod D, thus securing the reed when the shuttle is in the shuttle-
box at each end of the "slay." Between the booked projection E and the metallic
end L of the shuttle-box is disposed the leather or other pliable washer M to form a
cushion for the same when operated by the shuttle. Instantly the shuttle leaves the
shuttle-box A the hooked projection E assumes its normal position as in Fig. 2 by
the action of the spring I, thereby releasing the lever or finger K which will allow
the reed to fall out if caught or pressed by the shuttle in its flight through the "shed."
In case the shuttle comes in contact with the, reed when passing through the "shed
the lever or finger K will assume the position shown in dotted lines in Fig. 3.
"
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. Locking the reed in position in the "slay" of a loom by the action of the
shuttle when in the shuttle-box at each end of the "slay," and releasing the same on
the shuttle leaving the shuttle-box to pass through the "shed."
2. The combination of the hooked projection E mounted loosely on the shuttle-
spindle B, spring 1, washer M, and lever or finger K secured to the stop-rod D,
applied and operating substantially as described and shown on the drawings for the
purpose specified.
