Mechanical Engineer, and James Taylor, of Hollinwood, near Oldham,
Overlooker, for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 3rd November 1855, and dated the 3rd May 1855.
PROVISIONAL SPECIFICATION left by the said John Platt and James
Taylor at the Office of the Commissioners of Patents, with their Petition,
on the 3rd May 1855.
We, the said JOHN PLATT, of Oldham, in the County of Lancaster,
Mechanical Engineer, and JAMES TAYLOR, of Hollinwood, near Oldham, Over-
looker, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING" to be as follows:-
Our Invention relates to a method of preventing the shuttle from accidentally
flying from its race, for which purpose we adapt a rod or rods or other suitable
apparatus to the lathe, situate above the race, and extending across the width
of the warp threads.

by the said John Platt and James Taylor in the Great Seal Patent
Office on the 3rd November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, Jonn
PLATT, of Oldham, in the County of Lancaster, Mechanical Engineer, and
JAMES TAYLOR, of Hollinwood, near Oldham, Overlooker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of May, in the year of our Lord One
thousand eight hundred and fifty-five, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Platt and James Taylor, Her especial license that we, the said John
Platt and James Taylor, our executors, administrators, and assigns, or such
others as we, the said John Platt and James Taylor, our executors, adminis-
trators, and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," upon the condition
(amongst others) that we, the said John Platt and James Taylor, by an instru-
ment in writing under our hands and seals, or under the hand and seal of one
of us, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Jolm Platt, do hereby declare the
nature of our said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawing (that is to say) :-
:-
Our Invention relates to a method of preventing the shuttle from accidentally
flying from its race, for which purpose we adapt a rod or rods or other appa-
ratus to the lathe situate above the race, and extending across the width of
the warp threads. In the accompanying Drawing, Fig. 1 represents a portion
of a loom, in section, with our improvement adapted, and Fig. 2 is a front
view of the same. To the part a, which is mounted upon the lathe sword and
carries the reed, is attached a rod b, extending downward and occupying
a position above a portion of the race A. Should the shuttle arrive in contact
with
any obstruction during its passage, or from other circumstances be caused
to fly upward, the rod 6 operates as a stop, and prevents its flying from the

page_text: race. Fig. 8 represents, in section, a modification of our Invention, designed
chiefly to be adopted when temples are employed which extend across the
fabric; the difference in this case being, that as the work is beaten up, the guard
rod is caused to rise above the plane of the temple. The rod is shown at b
carried at each side of the loom by an arm c, mounted upon a stud d, capable of
turning upon its centre. This stud also carries arms e, f; the former of which
is forced outward by means of a spring 9 attached to the lathe, and the latter
acts as a stop against the elastic force thereof; by these means the rod 6 is
caused to assume the position shewn in the Drawing, and answer the purpose.
of a guard, as before described. Upon a centre pin of the lathe sword is
mounted a lever h, h*, the former part of which rests against the arm & and
spring 9; the latter is connected by a strap i to a fixed part j. Upon the
beating up of the work taking place, the centre of the lever h, h*, will
be carried forward, and as the portion * is detained by the strap i, it will be
caused to turn and compress the spring g by means of the part h, thereby
communicating motion to the arms e, f, and stud d, whereby the rod 6 will be
turned upward above the plane of the temple; upon the return motion of the
lathe taking place, the spring ġ will be liberated, and the rod 6 thereby lowered
into the position shewn, again ready to act as a guard above the shuttle race.
We have above described certain constructions and arrangements by which
our Invention may be carried into effect, but we desire it to be understood
that we do not limit ourselves thereto; for it is evident that in place of the
single rod b, two or more, or a description of cage may be adapted, and other
modifications made, which will suggest themselves to all competent persons;
that which we claim, as secured to us under the above in part recited Letters
Patent, being, the adaptation of a rod or rods or other apparatus extending
across the warp threads, for the purpose above set forth.
In witness whereof, I, the said John Platt, have hereunto set my hand
and seal, this First day of November, in the year of our Lord One
thousand eight hundred and fifty-five..
