page_text: 1, JAMES SHACKLETON, of No. 17 Wolseley Terrace, Battinson Road, Halifax,
Yorkshire, Weaving Manager, do hereby declare the nature of this invention to be as
follows:-
The object of my Invention is to provide automatic apparatus to be attached to the
"going parts" of looms to prevent the shuttle flying out of its course, which some-
times happens, in consequence of the speed at which the shuttle is sent across the
loom.
In carrying out my invention, I hinge on suitable brackets projecting from the
hand rail, or froin the horizontal rail fixed to the top of the reed, a hinged grate or
plate, which I elevate at the proper time for the shuttle to pass under, so as to
prevent its flying from its course, but immediately after the shuttle has arrived
home," the said hinged plate is automatically made to close or assume a vertical
position, so that as the slay beats up, the grate or plate does not project outwards,
nor cover the warp, nor the cloth being woven. The means I employ for oscillating
the said plate consists of a bell crank or other form of lever, suitably hinged under
the breast beam, the forward end of which is connected by a stud to the oscillating
plate, the arrangement being such that on the beat up of the slay the bell crank
lever causes the grate to close against the reed, but when the slay recedes the action
of the bell crank lever operates the said grate or plate so as to make it assume the
horizontal position for the shuttle to pass under, and this goes on every time the loom
picks.
By the application of the hinged grate or plate, it is impossible for a shuttle to
fly from its course and do the serious damage which often happens thereby, whilst at
the same time the hinged grate or plate does not cover up the last shoot of weft nor
prevent the weaver from seeing the warp.

page_text: A New or Improved Apparatus for Preventing Loom Shuttles
Flying from their Course.
I, JAMES SHACKLETON, of No. 17, Wolseley Terrace, Battinson Road, Halifax,
Yorkshire, Weaving Manager, 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 :-
The object of my invention is to provide automatic apparatus to be attached to the
"going parts" of looms to prevent the shuttle flying out of its course, which some-
times happens, in consequence of the speed at which the shuttle is sent across the
loom.
In carrying out my invention, I hinge on suitable brackets projecting from the
hand rail, or from the horizontal rail fixed to the top of the reed, a hinged grate or
plate, which I elevate at the proper time for the shuttle to pass under, so as to
prevent its flying from its course, but immediately after the shuttle has arrived
home" the said hinged plate is automatically made to close or assume a vertical
position, so that as the slay beats up, the grate or plate does not project outwards,
nor cover the warp nor the cloth being woven. The means I employ for oscillating
the said plate consist of a bell crank or other form of lever, suitably hinged, the
forward end of which is connected by a stud to the oscillating plate, the arrangement.
being such that on the beat up of the slay the bell crank lever causes the grate to
close against the reed, but when the slay recedes the action of the bell crank lever
operates the said grate or plate so as to make it assume the horizontal position
for the shuttle to pass under, and this goes on every time the loom picks.
To
Such being the nature and object of my invention, I will now proceed to describe
the same more fully, and for that purpose make reference to the accompanying sheet
of drawings, wherein Fig. 1 is sectional elevation of so much of a loom as is necessary
to illustrate my invention. a is the framework of the loom, b the slay or going part,
and the reed, made secure to the horizontal hand rail d in the usual manner.
the top rail d I fix suitable brackets e, on which is hinged by pins fa grate or plate g,
sufficiently long to cover the racecourse on which the shuttle is sent. A link h is
employed, one end of which is connected to the grate, whilst the other end is con-
nected to the vertical slotted bar i, so that when the crank has reached its furthest
point from the breast beam j, and just at the time before the shuttle is sent from
either end of the shuttle box, the outward motion of the slay causes the grate to be
elevated as shewn in Fig. 1, permitting the shuttle & to be sent across the loom,
but should the shuttle get from its course and fly upwards it would strike against the
grate and thus be prevented from going any further and doing damage thereby, but
when the going part beats up towards the breast beam, then the grate is made to
assume the position shewn in Fig. 2, which is no detriment to the beating up of the
weft, nor is it any detriment to the weaver when she requires to examine

page_text: or find broken picks. Fig. 3 is an elevation of a grate. In order to prevent rigidity
or stiffness of the parts the upright bar i is secured by a nut n to a bracket 7, safely
secured to another bracket m attached to the breast beam of the loom. It will be
apparent that the stud n forms a fulcrum for the upright bar i to work upon, whilst
the stud o is free to oscillate in a slot formed in the bracket 1, as shewn in edge
view Fig. 4, and in order to give additional freedom to the parts, the bottom part
of the bar i is made hollow for the reception of a stud p, projecting up from a boss
working upon the inclined plane 9, by which means the upright bar i is free to move
upon its fulcrum.
By the application of the hinged grate or plate, it is impossible for a shuttle to fly
from its course and do the serious damage which often happens thereby, whilst at the
same time the hinged grate or plate does not cover up the last shoot of weft nor
prevent the weaver from seeing the warp.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a loom for weaving, the employment of the oscillating grate or plate 9,
actuated in the manner substantially as shewn and described, for the purpose of
preventing shuttles flying from the shuttle race.
