PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition,
on the 19th January 1870.
I, EDWARD THOMAS HUGHES, of the Firm of "Hughes and Son," Patent
Agents, 123, Chancery Lane, London, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," a com-
munication to me from abroad by Isaac Edwin Newton, of Waterbury,
State of Connecticut, United States of America, to be as follows:-

"barrel springs," so as to be wound respectively at alternate beats of
the lay, and each let off at the proper time to drive the pickers from one
side to the other as the case be.
Fig. 1 of the Drawings represents a front view; Fig. 2, a side view;
Fig. 3, a top view; and Fig. 4, a section on line x, x, looking toward
the front.
A is the frame of the loom of any known construction; B, the lay,

arranged so as to work in the lay at their respective ends; F'and F¹ are
two "barrel springs" arranged in bearings f. The said springs being
constructed in the usual manner of "barrel springs" for other purposes,
and so that the spring is first wound by turning the shaft, while the
barrel remains stationary by means of square stems a extending through
the ratchets d, which have pawls e to confine them when the springs are
wound to the proper tension. The pickers are attached by cords or
chains L to the barrel. The said "barrel springs" having been wound
up by the stems and properly set to give them a certain degree of
strength are respectively operated on, and alternately further wound by
cams I and I' fixed upon the shafts N and N¹. Therefore suppose the
shuttle to have been thrown from one end of the lay by the picker E,
and that in the passage it has moved the picker E¹³ to the outer end of
the lay and rests against it, at this stage the cams and pickers will be
as represented in Fig. 4, and the cam I' in its further rotation in the
direction of the arrow marked near it will bear against the stud i on the
barrel, turn it, and thereby wind up and tighten the spring, and hold it
tightened until the point of the cam escapes from the stud,, when the
barrel being, free will be suddenly returned to the position shewn in
Fig. 4 at the left, and will draw with it the picker, which will throw
the shuttle through the stud to the opposite picker, which will bet
operated on by that picker and its connection or barrel. The barrel and
cam are represented at the right in Fig. 4 in the positions they occupy
with each other when the barrel has been wound up by the cam, and
the barrel remains in that position until the point of the cam passes
its pin, when it is suddenly turned and throws the shuttle. By this
operation the shuttle is thrown with equal velocity however slow or fast

page_text: the other portions of the loom may be moving, hence ensuring the
throwing of the shuttle entirely through to the opposite picker. The
force with which the shuttle is thrown may be regulated by turning the
ratchets a, to the shafts of which the inner ends of the springs are
attached.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Thomas Hughes in the Great Seal Patent
Office on the 19th July 1870.

NOW KNOW YE, that I, the said Edward Thomas Hughes, do hereby
declare the nature of the said Invention, and in what manner the

page_text: same, is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say :-
This Invention relates to an improvement in looms, especially in the
operation of the picker for throwing the shuttle, the object being to
throw the shuttle with the same velocity whether the loom be working
slow or fast, and the Invention consists in the arrangement of a pair of
"barrel springs," so as to be wound respectively at alternate beats of
the lay, and each let off at the proper time to drive the pickers. from one
side to the other, as the case may be.
Fig. 1 of the Drawings represents a front view; Fig. 2 a side view;
Fig. 3 a top view, and Fig. 4 a section on line X, X, looking toward
the front.
A is the frame of the loom of any known construction; B, the lay,
also of common construction and actuated in the usual manner, here
represented as by eccentric C on the shaft D; E and E' are pickers
arranged, so as to work in the lay at their respective ends; F and F are
two "barrel springs" arranged in bearings f; the said springs being con-
structed in the usual manner of "barrel springs" for other purposes, and
so that the spring is first wound by turning the shaft, while the barrel
remains stationary by means of square stems a extending through the
ratchets d, which have pawls e to confine them when the springs are
wound to the proper tension. The pickers are attached by cords or
chains L to the barrel. The said "barrel springs" having been wound_up
by the stems and properly set to give them a certain degree of strength
are respectively operated on, and alternately further wound by cams I
and I' fixed upon the shafts N and N'. Therefore suppose the shuttle to
have been thrown from one end of the lay by the picker E, and that in
the passage it has moved the picker E' to the outer end of the lay and
rests against it, at this stage the cams and pickers will be as represented
in Fig. 4, and the cam I' in its further rotation in the direction of the
arrow marked near it will bear against the stud i on the barrel, turn it,"
and thereby wind up and tighten the spring and hold it tightened until
the point of the cam escapes from the stud, when the barrel being free
will be suddenly returned to the position shewn in Fig. 4 at the left,
and will draw with it the picker, which will throw the shuttle through
the shed to the opposite picker, which will be operated on by that picker and
its connection or barrel. The barrel and cam are represented at the right

page_text: in Fig. 4 in the positions they occupy with each other when the barrel
has been wound up by the cam, and the barrel remains in that position
until the point of the cam passes its pin, when it is suddenly turned and
throws the shuttle. By this operation the shuttle is thrown with equal
velocity however slow or fast the other portions of the loom may be
moving, hence ensuring the throwing of the shuttle entirely through to
the opposite picker. The force with which the shuttle is thrown may be
regulated by turning the ratchets a, to the shafts of which the inner
ends of the springs are attached.
I do not wish it to be understood as broadly claiming the throwing of
the shuttle by the reaction of a spring, as such I am aware is not new;
but I claim as my Invention,-
First. In combination with the respective pickers E and E¹ the barrel
springs F and F¹ operated by the cams I and I' when arranged in the
manner described, so as to throw the shuttle as set forth.
Second. In combination with the above I claim the adjusting ratchets
d, d, and pawls e for the purpose specified.
In witness whereof, I, the said Edward Thomas Hughes, have here-
unto set my hand and seal, this Eighteenth day of July One
thousand eight hundred and seventy.
