Improvements in Shuttle Guards of Looms for Weaving.
We EPHRAIM HINDLE, and GEORGE HINDLE, Manufacturers, and WILLIAM
ISHERWOOD, Manager all of Bastfield Mills, Blackburn in the County of
Lancaster do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in shuttle guards of looms for weaving,
designed for the purpose of preventing the shuttle flying out of the race when the
loom is in motion, and consists of parts so arranged as to be put into operation
automatically when starting the loom, and to be moved out of the way of the
operative when the loom is stopped.
According to this our invention the shuttle guard consists of a rod, or strip of
metal extending from end to end of, and hinged to the front of the hand rail, and
to one end of such rod is attached a short metal arm, the other end of which, by
link, being attached to one end of a lever moving on a fulcrum stud fixed to the
slay sword, or to the shuttle race, the opposite end of the said lever carries a
runner which is pressed down on a horizontal lever, or arm by means of a spring.
The horizontal lever, or arm is carried at one end on a fulcrum stud, the other end
of same being connected to the vertical brake lever, and on said arm or lever we
form an inclined face, or dip."

The action is as follows:-When the loom is set in motion the brake lever raises
one end of the horizontal lever, or arm which by overcoming the pressure of the
spring raises the runner, and its end of the lever, consequently depressing the
opposite end thereby drawing down, by the link, the short metal arm, and turning
the rod, or strip of metal on its hinges so as to cover, and form a guard over the
when the forward
shuttle race, in which position it remains until the "beat up
" to the inclined face or
movement of the slay sword brings the lever, and "runner
"dip" in the horizontal lever, whereon the spring depresses the runner, and lever,
and by its connections forces the rod, or strip of metal close into the hand rail, and
out of the way of the temples during the "beat up," and when the shuttle is
"boxed." At the return movement the guard is again raised to the "active," or
safe position by the runner moving up the inclined face, or "dip," and overcoming
pressure of the spring, and while the shuttle is crossing the race.
the
In a modification of our invention we dispense with the horizontal lever, runner,
and connections, and in lieu thereof crank one end of the rod, or strip of metal, and
by a vertical connecting rod attach same to a lever working on a fulcrum stud, the
outer end of said lever being attached to the brake lever, and the action is similar
to that above described except that when the loom is started, and the guard
becomes "active" it remains in that position and does not close up to the hand rail
during the "beat up." When the loom is stopped a spring closes the strip, or rod
of metal up to the hand rail, and out of the way of the operative, and the said
spring may be either applied to the guard itself or to one of the connections, as, for
instance the runner.

Improvements in Shuttle Guards of Looms for Weaving.
We EPHRAIM HINDLE and GEORGE HINDLE Manufacturers and WILLIAM
ISHERWOOD Manager all of Bastfield Mills, Blackburn in the County of
Lancaster, 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 relates to improvements in shuttle guards of looms for weaving
designed for the purpose of preventing the shuttle flying out of the "race" when
the loom is in motion; and consists of a combination of parts so arranged as to be
put into operation automatically when starting the loom and to be moved out of the
way of the operative when the loom is stopped and at the "beat up."
According to this our invention the shuttle guard consists of a rod or strip of
metal extending from end to end of, and hinged to the front of the hand rail, and
to one end of such rod is attached a short metal arm the other end of which is by
link attached to one end of a lever moving on a fulcrum stud fixed to the slay sword
or to the under-side of the shuttle "race" the opposite end of the said lever carries
a runner which is pressed down on a horizontal lever, or arm by means of a spring
fixed to the under-side of the shuttle box or shuttle "race." The horizontal lever
or arm is carried at one end on the crank shaft which forms a fulcrum the other
end of same being connected by rod to the drop lever operated by the finger on the
stop handle. On said arm or lever we form an inclined face or "dip."
Such being the nature and object of our said invention the following is a
complete description of same, reference being made to the accompanying drawings in
which :-
Fig. 1. is an end view of our improved shuttle guard, and appliances connected
therewith.
Fig. 2. is a front view of Fig. 1.
Fig. 3. is an end view of our improved shuttle guard and appliances connected
therewith shewing the guard in the safe position assumed when the shuttle is
crossing the "race and drawn detached from the loom in order to more clearly
illustrate same.
"
Fig. 4. is a similar view to Fig. 3 but shewing the guard in the position assumed
when the shuttle is safely "boxed."
"
According to this our invention the shuttle guard consists of a rod or strip of
metal 1 extending from end to end of, and hinged to the front of the hand rail 2
and to one end of such rod 1 is attached a short metal arm 3 the other end of which
is by link 4, attached to one end 5, of a lever 6 moving and carried on the stop
rod 7 which forms a fulcrum stud or on a stud fixed to the slay sword 8 or to the
under side of the shuttle " race 9 the opposite end of the said lever 6 carried a
runner 10 which is pressed down on a horizontal lever or arm 11 by means of a
" The
spring 12 fixed to the underside of the shuttle box or shuttle race.'
horizontal lever or arm 11 is carried at one end on the crank shaft 13 which forms
a fulcrum the other end of same being connected by rod 15 to the drop lever 16
operated by the finger 17 on the stop handle 14. On said arm or lever 11 we form
an inclined face or "dip" 18. The link 4 is preferably made in two parts as shewn
in order to allow for adjustment. The rod or strip of metal 1 forming the guard is
hinged at each end of the hand rail 2 as shewn by Fig. 2 but in this fig. one end
only of the rod is illustrated.
The action is as follows. When the loom is set in motion by moving the "stop"
handle 14 in the direction indicated by the arrow in Fig. 2 the finger 17 moving
along the inclined face 19 of the drop lever 16 raises by the connecting rod 15 one
end of the horizontal lever or arm 11 which by overcoming the pressure of the
spring 12 raises the runner 10 and one end of the lever 7 consequently depressing

page_text: " runner
the opposite end 5 and thereby drawing down by the link 4 the short metal arm 3
and turning the rod or strip of metal I on its hinges so as to cover and form a
guard over the shuttle race (see Fig. 3) in which position it remains until the
"beat up" when the forward movement of the slay sword 8 brings the lever 6 and
10 to the inclined face or "dip" 18 in the horizontal lever or arm 11
whereon the spring 12 depresses the runner 10 and one end of lever 6 and by the
connections moves the rod or strip of metal 1 close into the hand rail 2 and out of
the way of the loom "temples" and operative during the "beat up" and when the
shuttle is "boxed" (see Figs. 1 and 4). At the return movement the guard 1 is
again raised to the "active" or safe position by the runner 10 moving up the
inclined face or
dip" 18 and overcoming the pressure of the spring 12 and while
the shuttle is crossing the "race."

"
It will be seen that by the above described appliances the shuttle guard is
automatically placed in the "safe" position only when the shuttle is crossing the
race and when there is any opportunity of the shuttle "
"flying out and during
the "beat up" the guard lies close against the hand rail and out of the way.

.
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.
The lever or arm 11, lever 6 link 4 arm 3 and rod or strip or metal 1 all in
combination, operated and operating in the manner described and substantially as
illustrated by the annexed drawings.
