PROVISIONAL SPECIFICATION.
Improvements in Loom Shuttle Guards.
We GEORGE JENNINGS, and ALBERT TUTILL JENNINGS, of the firm of
George Jennings and Son, Central Works Thornton Road, Bradford, in the
County of York, Machine Makers, do hereby declare the nature of this invention
to be as follows:
This invention relates to certain improvements in shuttle guards, and has for its
object the arrangement and combination of the same in such a manner that,.
whenever the loom is put in motion, the guide bar will be moved into such position
that, should the shuttle be diverted from its regular course, it cannot leave the
loom and thereby endanger the personal safety of the attendant: also to so connect:
some portion of the "starting rod" of the loom with the guide bar, that a positive
and automatic motion for operating the said bar is obtained, and when the loom is
at rest, for the guide bar to be clear of the reed space so that the weaver may have
free access to the reed and warp.
We accomplish our object in the following manner: To the hand rail of the loom.
we secure two or more brackets which suppert short shafts, to one end of each of
which is secured a lever, the two levers being connected together at the bottom by the
shuttle guide bar. To the opposite end of one of the shafts is secured another lever
connected by rods and levers with a slotted bracket secured to the "starting rod "
by the operation of which, when putting the loom in motion or stopping the same,
the shuttle guide bar is operated in accordance therewith, the guard bar being in
such position when the loom is in motion that the shuttle cannot "fly" from its
usual course across the loom, and when the latter is at rest the guard bar is moved
clear of the reed space and warp, thus leaving the same open to the full inspection;
of the attendant.

COMPLETE SPECIFICATION.
Improvements in Loom Shuttle Guards.
We, GEORGE JENNINGS, and ALBERT TUTILL JENNINGS, of the firm of
George Jennings and Son, of Central Works, Thornton Road, Bradford, in the
County of York, Machine Makers, 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 certain improvements in shuttle guards, and has for its
object, the arrangement and combination of the operative mechanism in such a
manner that, whenever the loom is put in motion, the shuttle guard bar will be
operated and moved into such a position that, should the shuttle be diverted from
its regular course, it cannot leave the loom and thereby endanger the personal
safety of the attendant or other persons standing near the loom; and to so connect
the "starting rod" of the loom with the shuttle guard bar that, a positive and
automatic motion is imparted to the latter and when the loom is at rest for the guard
bar to be in such a position, that it is clear of the reed space and thereby enable
the weaver to have free access to the reed and warp.
In the accompanying drawings
Fig. 1. represents certain portions of a loom with our improved mechanism
applied thereto.

page_text: Fig. 2. is an end view of the same.-
Fig. 3. a plan of what is known as the hand rail with the guide bar mounted
thereon; and
Fig. 4. a cross section. through line a. b.³
To the hand rail A. of the loom, we secure two brackets B. each supporting a
short shaft, to one end of each of which is. secured a lever C. the two levers being
connected at the bottom by the shuttle guard bar, D. provided in the centre with an
upright bar. E. engaging with a slot hole cut in bracket F: secured to the before,
mentioned hand rail A. by which means the vibration. of the shuttle, guard is
reduced when the loom is in motion.
To the opposite end of one of the before mentioned short shafts is secured another
lever, or the lever C. may be extended at C' as shown in the drawings and to
which is connected a rod G. coupled to a lever H.-mounted on a shaft-supported-by
a bracket J. attached to the lathe K. of the loom. To this shaft is secured a
lever L. projecting downwards and in contact with the bracket or bar M. secured to
the "starting rod" N. by the operation of which on putting the loom in motion or
stopping the same, the lever L. is operated and thereby the levers C. and shuttle
guard bar D. raised or lowered according to the-position of the "starting rod" N.
When the loom is in motion the shuttle guard bar D: is in the position shown by.
full lines in the drawings, such a distance above the warp so as to clear the same
but prevent the shuttle leaving the loom should it be diverted from its'regular
course, and when the loom is at rest, the shuttle guard bar D. by the operation of the
"starting rod" N is automatically raised to the position shown by dotted lines clear
of the reed space, thereby giving access to the warp for repairs and inspection.
Having now particularly described and ascertained the nature of this inven,
tion and in what manner the same, may be performed, we declare that what we
claim is :-
The combination of the parts forming the complete apparatus-arranged-sub-
stantially as and for the purpose hereinbefore set forth and illustrated by the
accompanying drawings.
