worth at the Office of the Commissioners of Patents, with their Petition,
on the 5th September 1861.
I, DANIEL HEYWORTH, of Featherstall Mill, Littleborough, in the County of
Lancaster, Manager, and JOHN HEYWORTH, of the City of Manchester, in the
said County, Manager, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention consists, firstly, in an arrangement of apparatus for prevent-
ing the shuttle from passing out of its true course, or what is generally termed
flying out," across the front of the handrail of the loom, by which the top of the
reed is supported; we carry a piece of metal or other suitable material forming
a bar or rod supported at or near each end by bearings on brackets attached to
the lathe or slay-sword, this bar or rod is suitably cranked at each end so that by
connection with some convenient part or parts of the loom the desired motion
is obtained; when the loom is in motion the bar or rod is elevated to such a
position as to prevent the shuttle from "flying out," this may be effected in
various ways either by means of a spring attached to a crank at one end of the
bar or rod and connected to the lathe, slay-sword, crank arm, side of loom, or
other part of the loom as may be deemed most convenient, or by rods and levers,
connecting the crank on the bar or rod with any moving part that would give
the required motion when the loom is at rest (by means of a band or strap
coupling the crank on the bar or rod with the setting-on rod or stop rod) the
bar or rod is planted against the face of the reed in such a manner as to prevent

page_text: the weaver's hook damaging the dents of the reed. In some cases where the
reed is particularly high it may be advantageous to place a bar or rail below
the hand rail in order to support the bar or rod with the necessary brackets
and bearings. This we call "the self-acting shuttle and reed protector."
Second, the swell in the shuttle box is of a peculiar form and fixed in its
place by means of a leather hinge. Behind the swell are projections so
arranged as to form bearings for a small pulley or stud over which is passed a
band or strap, which passing through opposite ends of the back of the shuttle
box is adjusted on the picker spindle in such a manner that on the shuttle being
driven into the shuttle box the strap is tightened, and pressing against the
back of the swell prevents the shuttlo from rebounding, In order that
the shuttle may freely enter and leave the shuttle box without being bound by
the action of the finger on the stop-rod pressing against the swell, we have
fixed on the crank arm or loom side, a bracket supporting a short lever
working on a stud and held in position by means of a spring; on the end of the
lever is an irregular form fixed on its side, round which moves a pulley fixed
at the end of another lever supported by the slay swords, which latter lever
being connected by a spring with a projecting hook on the stop rod during the
motion of the loom, the swell is relieved from all pressure by the finger of
the stop rod. This we call "the improved shuttle check."
Third, the rib or plate of wood or iron forming the front of the shuttle box
at the end nearest to the reed space is of such a curved form as to guide the
shuttle into the box should it slightly deviate from its true course when the
loom is in motion. This we call "the shuttle guide."
Fourth, immediately behind the breast beam we have fixed a rod or spring
extending the full width of the reed space, and so arranged as to press against
the under side of the cloth, thus slightly raising the same (but more especially
in the centre) by this means we obtain a greater degree of body on the face
of the cloth. This we call "the cloth improver."
Fifth, on the wheel working in the pinion on the crank shaft a stud is fixed,
which at each revolution of the wheel acts upon a lever working upon a stud
attached to the loom side connected to one end of which lever is fixed a clip
through which is passed an endless band or strap perforated with a number of
holes and passing over a pulley having a number of pegs on its rim corre-
sponding with the holes in the band or strap, and at some convenient distance
immediately below the centre of the pegged pulley working on a stud, and
coupled with the pinion; placed on the end of the roller, termed the cloth beam,
is fixed a small pulley round which the band or strap moves, and which can
be raised or lowered in order to slacken or tighten the band or strap as may

page_text: be desirable on the lever being depressed by contact with the stud on the
pinion wheel. The clip tightly holding the band or strap causes the wheel or
pulley on the cloth beam to move, and there being a slot in the pinion wheel
through which the stud is passed, the required degree of motion is easily
obtained. This we call "the improved taking up motion."
Sixth, fixed to the side of the loom we have a bracket so arranged as to
form a socket, in which the cranked end of a lever which having a projecting
rib pressing against the warp passes alongside or under the warp beam. To the
other end of the lever are connected chains, ropes, or straps passing over pullies
to the centre of back of warp beam or immediately underneath and attached
to weighted pullies working upon the levers for weighting the beam, as the
warp passes off the beam the weights gradually slide down the levers, and con-
sequently create less strain upon the warp, more or less strain can be obtained
by placing lighter or heavier weights on the pullies on the levers as may
be desirable. This we call "the letting-off motion or beam weight regulator."
Seventh, on the jack wires connected to the headles we have on one side
a plate, which having a half round bottom rests upon the treadle, in the centre
of the plate is a bole, and passing through which a bolt, we are enabled to
screw the same tightly to the jack wires which causes the same to work much
better and prevents the bottom of the healds from coming in contact and
damaging each other. This we call "the improved treadle jack."
Eighth, fixed at the bottom of the loom side we have a spring connected
with the setting-on rod, the upper portion of the spring is bent at right angles
and so arranged as to prevent the stop rod from rising on the loom being
stopped. This we call "the stop rod catch."
