IMPROVEMENTS IN SHUTTLE GUARDS
Year: 1885

page_text: We, NATHAN DRAKE of West Brook Shed, Shearbridge Road, Bradford, in the
County of York, Manufacturer, and SMITH FEATHER, of the same place, Manager,
do hereby declare the nature of our invention for IMPROVEMENTS IN SHUTTLE
GUARDS to be as follows:-
This invention has for its object the construction of an efficient self acting
shuttle guard, that will move into such a position on setting the loom in motion,
that should a trap occur, the shuttle is prevented flying out of the "shed," and
thereby endangering the personal safety of the weavers or attendants: and on
stopping the loom the guard will be moved clear from the warp and reed, which
we accomplish in the following manner.
Near to the ordinary starting rod of the loom, we mount a lever that is in
contact therewith, and is arranged with a long arm to which is attached a rod
connecting the same with a series of levers mounted to the top bar or hand rail of
the going part reed case, by which, when the starting rod is moved into the position
for starting the loom; the levers lower the guard board or plate a certain distance
sufficiently clear of the warp; that should a shuttle be "trapped," it cannot fly
away from the fabric, but is retained on the going part of the loom.
When the starting rod is moved to stop the loom, the levers mounted on the top
rail.are actuated, and thereby raise the guard board or plate clear of the warp and
reed, so that the weaver or attendant has free access to the same.

page_text: We, NATHAN DRAKE, of West Brook Shed, Shearbridge Road, Bradford, in the
County of York, Manufacturer, and SMITH FEATHER of the same place, 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 invention has for its object, the construction of an efficient self acting
shuttle guard to be moved into such a position on setting the loom in motion, that
should a "trap" occur, the shuttle is prevented flying out of the "shed," and thereby
endangering the personal safety of the weavers or attendants; and on the stopping
of the loom, the said guard is moved clear from the warp and reed, by which the
cloth, reed, and warp are open to the full view of the attendants.
The invention consists in so arranging and connecting a series of levers, that
when the loom is started, the shuttle guard consisting of a rail placed parallel to
the reed, and supported by levers, is lowered down in front of the reed sufficiently
clear of the warp, so as not to interfere with the work, but to effectually prevent
the shuttle escaping from the loom should a "trap" occur.
In the accompanying drawings, Fig. 1 represents such portions of the end frame
of a loom as are required to explain our invention. Fig. 2 is a front view of the
same, and the remainder of the figures are detached details. Fig. 6 being an
enlarged view of the lever B.
Near to the ordinary starting rod A, we mount the lever B, one arm of which is
in contact therewith, the said lever is also arranged with another arm B¹ to which
is attached a slotted plate C, that is fitted with a stud upon which is mounted one
end of a connecting rod D, the other end being attached to an arm or lever E.
This arm or lever is secured to a short shaft, that is mounted on a bracket attached
to the top bar or hand rail F, of the lathe or going part, and to the opposite end of
the said shaft, we secure a similar arm or lever E¹.
Near to the other end of the hand rail F, we attach another bracket, and mount
thereon a short shaft, to which is secured another arm or lever E¹. These arms or
levers support the guard rail or plate G, which is lowered as hereafter described, to
within a short distance of the cloth, and by the guard rail or plate G, moving parallel
to the hand rail F, and extending practically from shuttle box to shuttle box, it is
next to impossible for the shuttle to leave the loom.
When the loom is stopped, the guard rail G, rises to the position as shewn by
full lines in the drawings, thereby leaving the cloth, warp, and reed clear, all
being open to the full view of the attendant, as is the case when no shuttle guard
is used.
Figs. 3, 4, and 5 are details shewing the means we employ for keeping the guard
rail G, parallel with the hand rail. To the face of the latter we secure one or
inere hooks H, the end of each of which is placed in the space formed by the
respective staples J, between the latter and the guard rail, thereby preventing the
guard rail vibrating with the action of the loom and doing damage to the fabric.

page_text: When the loom is started, the rod A, being in contact with one arm of the
lever B actuates the same, causing the arm B¹, plate C attached thereto, and rod D,
to move in an upward direction, thereby operating the levers or arms E and E',
thus causing the guard rail or plate G to be lowered to the position shewn by
dotted lines in Fig. 2.
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
The guard rail or plate G mounted in front of the hand rail F, substantially in
the manner and for the purpose described.
The combination of the starting rod A with the
and E, and the guard rail or plate G, in the
described.
