We THOMAS CALVERT, Mill Manager of 25 Brackenbury Street, Preston, and
JOHN HUNT, Pawnbroker, of 4 Imperial Terrace, St. Paul's Road, Preston, in the
County of Lancaster do hereby declare the nature of this invention to be as
follows:-
By this invention the shuttle guard which covers the whole length of the reed
space is firmly fixed to the slay cap, or hand rail and thus prevent the shuttle from
flying out when the Loom is in motion, and as soon as the Loom stops the shuttle
guard by an automatic action is turned back, and is out of the way of the Weaver,
and this action is effected as follows. A bar, or shuttle guard goes the whole length
of the reed space, and this said guard is actuated by being connected to a short lever
at the end which lever is connected to a rod passing down at the back of the shuttle
box, this said rod is brought down to the bottom of the slay sword, and connected to
a lever that is on a level with the centre of the swing rail, and this bottom lever is
connected to the brake lever-rod of the Loom, and by this arrangement when the
Loom is stopped, the shuttle guard is thrown back, thus leaving the reed space free
of access by the weaver, and we claim the above improvement for automatic shuttle
guards as our invention for which we apply for a patent.

page_text: We, THOMAS CALVERT, Mill Manager of 25 Brackenbury Street, and JOHN HUNT
Pawn Broker of 4 Imperial Terrace St. Pauls Road both of Preston 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 :-
By this invention the shuttle guard which is made of angle iron (or any other
suitable material) cover the whole length of the reed space directly over the warp
and shuttle race. This said guard is firmly fixed to the slay cap or hand rail by
joints at each end, and being always directly over the shuttle race when the Loom is
in motion it prevents the shuttle from flying out, but as soon as the Loom is stopped
this said guard by an automatic action (effected by being connected to the brake
lever rod and stop handle of the Loom) is turned directly under the hand rail and in
this position is out of the way of the weaver as if it did not exist.
The above describe the nature and object of our invention, and the following with
the use of the accompanying Drawings shows in what manner the above named
object is effected.
In the Drawings Fig. 1 & 2 shows a front and end view of the general arrangement
for working the guard. Fig. 3. is an enlarged section of the angle guard bar.
The guard is worked automatically from the stopping and starting handle "A."
The connection being made by lengthening the brake lever rod "B" which is
attached to a balance lever and weight "C." This Lever is carried by bracket "D"
bolted to the Loom frame "M" and fixed in such a position that the connecting
rod "E" is at about the same centre as the swing rail "I" and thereby gets the
sante motion as the slay cap "K." This said rod "E" is carried up behind the
Shuttle box "F," and parallel with the slay sword "J," and attached to the Guard
Bar "G" by a small Lever "H." This Guard "G" which is in the form of an angle
bar is carried at each end of the Slay Cap "K" by bearings "L," and is so fixed
that during the working of the Loom it being directly over the Shuttle race prevents
the shuttle from flying out, and when the Loom is stopped, the said Guard is turned
directly under the Slay Cap "K," (the arrangement for which being shown by the
dotted lines in Fig. 2) and thereby being no hindrance to drawing in the ends and
other purposes required in working the Loom.

page_text: Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, it is to be noted that we do not
claim the novelty of working the Guard automatically from the stopping and starting
handle, as we are aware such is not new. But what we do claim is
The connection and combination of parts from the Brake Lever rod "B" together
with the Balance Lever and weight "C" and connections "D, E, H," and also the
angle shaped Guard Bar "G" as herein arranged, described and shown by the
accompanying Drawings.
