AN IMPROVED SHUTTLE GUARD FOR USE IN LOOMS FOR WEAVING
Year: 1885

page_text: We, ARTHUR WILKINSON, of Stansfield House, Newton Moor, near Hyde, in the
County of Chester, Cotton Mill Manager, and JOSEPH SHAWCROSS, of Swindells
Street in the same place, Mill Mechanic, do hereby declare the nature of said
invention for "AN IMPROVED SHUTTLE GUARD FOR USE IN LOOMS FOR WEAVING"
to be as follows:-
This Invention of an improved shuttle guard for use in looms for weaving
consists in arranging a guard rod mounted on the ends of pivotted arms capable of
radial movement in such manner that the rod when down or in working position
over the shuttle may be locked and securely held in its place; and when required
to be moved out of the way it may, by receiving a side pressure from the
attendant, be released or put out of gear with the locking mechanism.
To this end the guard rod (which is preferably of the cross section known as
"half round") is secured at the desired intervals to the extremities of two or more
arms whose other ends work on pivots or pins forming bearings. The curved face
of the rod is on the lower side when the apparatus is in working position. The
pin constituting the pivot or bearing is carried at each end in ears or lugs projecting
from a plate fastened to the front of the slay cap. Between the pivotted end of
the arm and one of the projecting ears or lugs there is an interval or space occupied
by a spiral spring which pushes the arm (and with it the guard rod) against the
opposite projecting ear. The lower corner of the plate on the opposite side to the
spring is provided with a curved projection having a notch or slot into which one
side of the arm is pushed by the side pressure of the spring and remains firmly
locked therein when the guard rod is brought down into working position. When
it is desired to move the guard rod out of the way the rod is first moved sidewise
against the spring until the arm is clear of the locking device or notch when it
may be turned over in an upward radial direction.

We, ARTHUR WILKINSON, of Stansfield House, Newton Moor, near Hyde, in the
County of Chester, Cotton Mill Manager, and JOSEPH SHAWCROSS, of Swindell's
Street, in the same place, Mill Mechanic, 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 of an improved shuttle guard for use in looms for weaving
consists in arranging a guard rod mounted on the ends of pivotted arms capable of
radial movement in such manner that the rod when down or in working position
over the shuttle may be locked and securely held in its place; and when required
to be moved out of the way it may, by receiving a side pressure from the attendant,
be released or put out of gear with the locking mechanism.
The accompanying Drawings, of which Figs. 1, 2, and 3 are respectively side,
plan, and end views, illustrate the construction and application of our improved
shuttle guard to an ordinary form of slay cap.
The guard roda (which is preferably of the cross section known as "half round")
is secured at the desired intervals to the extremities of two or more arms b. b whose
other ends work on pins or pivots c. c forming bearings. The curved face of the
rod a is on the lower side (as shewn) when the apparatus is in working position.
The pin c constituting the pivot or bearing is carried at each end in ears or
lugs d. d projecting from a plate e fastened to the front of the slay cap f. Between
the pivotted end of the arm 6 and the projecting ear or lug d¹ there is an interval
or space occupied by a spiral spring g which pushes the arm b (and with it the
guard rod a) against the opposite projecting ear d. The lower corner of the plate
on the opposite side to the spring is provided with a curved projection / having &
notch or slot i into which one side of the arm b is pushed by the side pressure of
the spring g and remains firmly locked therein when the guard rod is brought
down into working position. When it is desired to move the guard rod out of the
way the rod b is first moved sidewise against the spring g until the arm is clear of
the locking device or notch i (as shewn in dotted lines in Fig. 1) when it may be
turned over in an upward radial direction (as shewn in dotted lines in Fig. 3).

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. In a shuttle guard for use in looms for weaving the use or employment of a
spring g operating in relation to a locking catch h substantially as described and
shewn in the Drawings.
2. The combination of parts constituting the improved shuttle guard constructed
arranged and operating substantially as described and shewn in the Drawings.
