PROVISIONAL SPECIFICATION.
Improvements in Shuttle Guards for Looms.
We, GWINNETT GEORGE TYLER, CHARLES EUSTACE PARRY TYLER, CEOIL DACRE
TYLER, and WYNDHAM RONALD WOODVILLE TYLER, all of Mount Gernos House,
Llandyssil, in the county of Cardigan, mill owners, and WILLIAM DAVIES, of
Llandyssil aforesaid, fitter, do hereby declare the nature of this invention to be as.
follows:-
This invention, which relates to looms, consists, firstly, in an improved guard for
preventing the shuttles leaving the shuttle board as they are shot to and fro along the
same in the process of weaving.
•
The improved guard consists of two bars fixed at a suitable distance apart,
extending horizontally along the slay and covering the shuttle board at all points in a
plane parallel to that of the travel of the shuttle.
The double guard is hinged at each end on the slay cap and is arranged to riso and
fall automatically on the hinges with the stopping and starting of the ioom, its
operation being, consequently, independent of the weaver.
This invention consists, secondly, in means for receiving the shuttle at each end of
the shuttle board. At each of these points is a guide plate the sides of which are
curved inwards so that should the shuttle strike the plate, it is thereby guided
into the shuttle box and thus prevented from leaving the shuttle board.

Improvements in Shuttle Guards for Looms.
We, GWINNETT GEORGE TYLER, CHARLES EUSTACE PARRY TYLER, CECIL DAORE
TYLER, and WYNDHAM RONALD WOODVILLE TYLER, all of Mount Gernos House,
Llandyssil, in the county of Cardigan, mill owners, and WILLIAM DAVIES, of
Llandyssil, aforesaid, fitter, 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 :—
This invention consists in means for preventing the shuttles of looms from "flying
out therefrom while being shot from one end of the reed space to the other in the
process of weaving.
The means in which this invention consists comprise a double rail guard extending
along the reed space of the loom and a pair of curved plates adjustably fixed, one at
each end, to the shuttle board for the purpose of directing the shuttle into the
shuttle box in event of the shuttle leaving its direct course and striking such
plate.
Should the shuttle be thrown out of its proper course it either strikes the guard
and is thereby stopped, or, if clear of the guard, it strikes one of the end guide plates
and is thereby stopped or directed into the shuttle box. The double rail guard is
hinged at each end to the slay cap or hand rail and is arranged to rise and fall with
the stopping and starting of the loom.
Fig. 1 on the accompanying drawing represents in front elevation a part of a loom
fitted with our improved means for preventing the shuttle from "flying out" whilst
the loom is at work. Fig. 2 is a part end view. Extending along the loom in front
of the reed space thereof are a pair of rods or rails a rigidly secured at the ends in
arms which are hinged on the slay cap ს.

page_text: When the loom is running, the double rail guard is in the position shown at Fig. 1
and, in firm lines, at Fig. 2.
If, as the loom works, the shuttle loaves its proper path while between the ends of
the guard it strikes the guard and is accordingly prevented from "flying out.”
The guard is so connected with the starting and stopping gear of the loom that it
rises when the loom is started and falls when the loom is stopped.
Under one arrangement, actuation of the guard is effected through a rod a connected
at the upper end to the cranked arm d of the guard. At the lower end the rod e is
fitted with an adjustable pin e secured in a slot in the box f hinged on the stud g on
which is an arm carrying an adjustable block in contact with the stop rod or hand
lever by which the driving belt is moved from the fast to the loose pulley or vice versu.
In stopping the loom the lever is depressed on its hinge by the stop rod & acting
through the block i, arm hand pin e. The rod e pulls down the guard which is brought
under the hand rail or slay cap b, as seen in dotted lines at Fig. 2, in which position
it is out of the way of the weaver when throwing in the shuttle or repairing broken
ends. A hinged hook or pawl may be employed to engage automatically with and
hold the guard when raised, as seen at Fig. 4, and until the pawl he disengaged
by the weaver from the guard the latter remains raised notwithstanding stoppage of
the loom.
The connection of the guard with the starting and stopping gear of the loom Day
be made in other ways, the method above described being adduced merely as an
example. At each end of the loom are guide plates & curved as shown in section
at Fig. 3. They are adjustable vertically and horizontally on the shuttle board.
If after passing beyond either end of the double rail guard a the shuttle should be
displaced from its course it strikes one of the plates and is thereby stopped or
directed into the shuttle box.
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. A shuttle guard for looms, being a frame consisting of two parallel rails, bars
or rods extending along in front of the reed space and rigidly secured at the ends
to arms hinged to the hand rail, the frame constituting the guard being so
connected with the starting and stopping gear of the loom as to rise when the
loom is started and to fall clear of the reed space when the loom is stopped,
substantially as herein before described.
2. In a loom the employment of guide plates adjustably secured to the shuttle
board at or near the ends thereof, said plates being so curved or dished that if struck
by a displaced shuttle the latter, if not thereby stopped, is directed into the shuttle
box, substantially as hereinbefore described.
3. The combination in a loom of the guide plates, and double guard rail a a with
means for actuating the latter as the loom stopped and started, substantially as
hereinbefore described.
