PROVISIONAL SPECIFICATION.
An Improved Shuttle Guard for Looms for Weaving.
I, JAMES LUND, of the Firm of William Lund and Son, of North Beck Mills,
Keighley, in the County of York, Worsted Spinners and Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention consists in constructing and arranging a new form of apparatus
for preventing shuttles from flying from the slay board or race course.
In constructing my improved apparatus I suspend to the hand rail of the loom a
shuttle guard consisting of a cranked horizontal bar capable of working freely in
eyelets composed of metal or of " gut." This horizontal bar is connected to a
vertical rod, the opposite end of which is attached to a lever connected to another
rod and bell crank lever actuated by the stop rod of the loom, the arrangement
being such that when the loom is weaving the horizontal bar connected to the hand
rail occupies a position projecting outward and would prevent the shuttle flying
from the shed, but when the loom is standing the stop rod would have so acted
upon the various levers and rods as to place the horizontal bar or shuttle guard
underneath the hand rail, and entirely out of the way of the weaver who would find
it no impediment when finding broken ends.
By means of the apparatus herein described an automatic shuttle guard is
provided and so arranged that when the stop rod is moved to start the loom the
shuttle guard is in position for acting, but when the stop rod is thrown off to stop
the loom the shuttle guard simultaneously therewith is placed out of position and
this movement of putting the shuttle guard in and out of position is effected without
any thought of the weaver as the movement of the stop rod in either direction
operates the shuttle guard.
Adjustable means are provided giving more or less movement to the shuttle
guard according to the size of shuttles employed and to the size of loom to which
the shuttle guard is applied.

COMPLETE SPECIFICATION.
An Improved Shuttle Guard for Looms for Weaving.
I, JAMES LUND, of the Firm of William Lund and Son, of North Beck Mills,
Keighley, in the County of York, Worsted Spinners and Manufacturers, 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 constructing and arranging a new form of apparatus
for preventing shuttles from flying from the slay board or race course.
In constructing my improved apparatus I suspend to the hand rail of the loom a
shuttle guard consisting of a cranked horizontal bar capable of working freely in
eyelets composed of metal or of "gut," such said shuttle guard being put into or
out of position by the action of the stop rod.
In order that the nature and object of my invention may be better understood I
will now proceed to describe the same, and for that purpose make reference to the
[Price]

page_text: accompanying sheet of drawings, wherein Fig. 1 is part end elevation of a loom
having my improvements applied thereto, and Fig. 2 is part front elevation of
same.
A represents the loom framing, B a portion of the lathe sword, C the slay or
running board, D the hand rail, and E the reed all employed in the ordinary
manner.
In two or more places in front of the hand rail I fix brackets F carrying the
cranked arms of the shuttle guard G which comprises one or more horizontal rods.
One end of the cranked arm is attached to a vertical rod H which is steadied and
kept vertical by an eyelet I attached to the slay board whilst the lower end of the
vertical rod H is connected to a short horizontal lever J the opposite end of such
lever being connected to another vertical rod K the top being attached to one end
of a bell crank lever L working upon a fulcrum at M the other end of the said bell
crank lever being slotted to receive a short rod N connected to the stop rod lever O.
The drawing shews the shuttle guard as being out of position and the loom to be
stopped, which would permit the weaver to get at the warp for tyeing in or other
purposes, but when the loom is set oh and weaving, the shuttle guard assumes the
position shewn in dotted lines at P in Fig. 1 ready for preventing the shuttle from
flying out of the shed. It is therefore evident that on the stop rod handle being
moved to stop the loom the shuttle guard is put out of action, but the opposite
movement of the stop rod handle sets the loom on and puts the shuttle guard into
acting position, therefore whether the loom stops through the action of the weaver
or whether through the absence or breakage of weft the shuttle guard is thrown
out of position but is always re-instated when the loom is set on, and this is done
without any thought or meditation of the weaver. The bottom of vertical rod K
is formed with screw threads R, so as to be adjustable in its length in order to
provide more or less movement to the shuttle guard according to the size of shuttles
employed and to the size of loom to which the shuttle guard is applied. In Fig. 3
I have shewn the shuttle guard G provided with three cranked arms for giving the
shuttle guard additional support but for narrow loonis the central bracket will not
be required.
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 :-
A shuttle guard for looms operated by the stop rod through the intervention of
bell crank lever L and vertical rods H and K in combination with the short lever J
all operated in the manner substantially as shewn and described.
