IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1867

page_text: LETTERS PATENT to William Gadd, of 122, Portland Road, Nottingham,,
Consulting Engineer, and John Moore, of Manchester, for the Invention
"
PROVISIONAL SPECIFICATION left by the said William Gadd and John
Moore at the Office of the Commissioners of Patents, with their Petition,
on the 30th July 1867.
We, WILLIAM GADD, of 122, Portland Road, Nottingham, Consulting
Engineer, and JOHN MOORE, of Manchester, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as
follows:-
The object of the Invention is to enable the shuttle to run at increased
speed with safety and security and less wear in its action. Shuttle boxes as
usually constructed have a fixed or rigid front with the "swell" to act on the
stop rod placed in the back thereof, so that the shuttle is received between
the swell and the box front, and considerable pressure is necessarily applied to
the swell to check and hold the shuttle after each throw until the next pick.
This pressure bears the shuttle against the front of the box, aud in order that
the shuttle may freely pass into the boxes the fronts of the boxes are brought
forward, and that end of them next the yarns to the greatest extent, so that
the pressure of the "swells" on the shuttle throws the shuttle forward out of

page_text: its direct course against the fronts of the boxes. By this present arrangement
the box fronts are at an angle to in place of parallel with the line of traverse of
the shuttle or the front of the reed, the tendency of which is to throw the
shuttle out and prevent great speed.
The object of our improvements is to remedy 'these evils. For this purpose
the front of each shuttle box or a part thereof in place of being wholly a
fixture is free to turn upon a pin at or near its end farthest from the yarn,
and such moveable fronts are on their inner surfaces next the shuttle some-
what of the form of the "swell." These moveable box fronts or parts thereof
are held in position by springs with stops, which may be adjustable to prevent
the ends of these moveable parts next the yarn from being pressed in too
close, so as to prevent the entrance of the shuttle. By these means the
shuttle may be held close to the box back during the whole time of its
delivery with a gentle pressure, and its motion when thrown may be direct
across the reed. These moveable fronts or portions thereof thus also act on
the shuttle as the ordinary "swells."
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Gadd and John Moore in the Great Seal Patent
Office on the 30th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
GADD, of 122, Portland Road, Nottingham, Consulting Engineer, and JOHN
MOORE, of Manchester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Fler reign,
did, for IIerself, Her heirs and successors, give and grant unto us, the said
William Gadd and John Moore, Her special licence that we, the said William
Gadd and John Moore, our executors, administrators, and assigns, or such
others as we, the said William Gadd and John Moore, our executors,
administrators, 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 IR LOOMS FOR WEAVING," upon
the condition (amongst others) that we, the said William Gadd and John
Moore, our executors or administrators, by an instrument in writing under

page_text: our or their hands and seals, or under the hand and seal of one of us or them,
should particularly describe and ascertain the nature of the said Invention,
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 William Gadd, on behalf of myself
and the said John Moore, do hereby declare the nature of the said Invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof:-
The object of the Invention is to enable the shuttle to run at increased
speed with safety and security, and with less wear in its action. Shuttle
boxes as usually constructed have a fixed or rigid front with the "swell" to
act on the stop rod placed in the back thereof, so that the shuttle is r ceived
between the swell and the box front, and considerable pressure is pessarily
applied to the swell to check and hold the shuttle after each throw until the
next pick. This pressure bears the shuttle against the front of the box, and
in order that the shuttle may freely pass into the boxes the fronts of the boxes
are brought forward, and that end of them next the yarns to the greatest
extent, so that the pressure of the "swells" on the shuttle throws the shuttle
forward out of its direct course against the fronts of the boxes. By this, the
present arrangement, the box fronts are at an angle to in place of parallel
with the line of traverse of the shuttle or the front of the reed, the tendency
of which is to throw the shuttle out and prevent the employment of great
speed.
The object of our improvements is to remedy these evils. For this purpose
the front of each shuttle box or a part thereof in place of being wholly a
fixture is free to turn upon a pin at or near its end farthest from the yarn,
and such moveable fronts are on their inner surfaces next the shuttle some-
what of the form of the "swell." These moveable box fronts or parts thereof
are held in position by springs with stops, which may be adjustable to prevent
the ends of these moveable parts next the yarn from being pressed in too
close, so as to prevent the entrance of the shuttle. By these means the
shuttle may be held close to the box back during the whole time of its
delivery with a gentle pressure, and its motion when thrown may be direct
across the reed. These moveable fronts or portions thereof thus also act on
the shuttle as the ordinary "swells."
But that the Invention may be fully understood we will, by the aid of the
accompanying Drawing, proceed to describe means pursued by us in carrying
the same into effect.

page_text: DESCRIPTION OF THE DRAWING.
Figure 1 shows by a plan view and Figure 2 by a front view a portion of
the batten of a loom with a shuttle box having parts arranged according to
our Invention. In each Figure the same letters indicate corresponding parts,
a representing one end of a batten; b, the box back; c, the "swell;" and d,
the picker spindle, all which are of the ordinary character; e is the box
front, which, according to our improvements is moveable, as shown; it is
capable of turning upon a stud f carried by the batten, and it is borne upon
with elastic pressure by the end g¹ of a spring 9, the other end of which is
by screws g² fixed to the batten; h and i are screw stops capable of adjust-
ment in the fixed brackets h¹ and to adjust the distance of motion of the
moveable box front e in either direction on its axis f. The screw stop h acts
on the outer end of the front e; the stop i acts on a tail piece e' formed on or
affixed to the front e.
We would here state that although we have shown the whole of the front
of the box moveable a part of it may be a fixture and a part moveable.
Having thus described our Invention, and means which we adopt in carrying
the same into effect, we would have it understood that we do not confine our-
selves to the precise details shown and described, so long as the peculiar
character of the Invention be retained substantially as described.
In witness whereof, the said William Gadd, have hereunto set my hand
and seal, this Twenty-eighth day of January, in the year of our
Lord One thousand eight hundred and sixty-eight.
WILLIAM GADD. (L.D.)
