and Samuel Bonser at the Office of the Commissioners of Patents, with
their Petition, on the 4th October 1865.
We, JAMES WADSWORTH, of Heaton Norris, in the County of Lancaster,
and THOMAS HALL, of Stockport, in the County of Chester, and SAMUEL
BONSER, of Stockport, in the County of Lancaster, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE TAKING-UP MOTIONS
OF LOOMS FOR WEAVING," to be as follows:-
In one arrangement we place a rod above or below the cloth beam-between
the last lap of the cloth and the cloth on the beam, and when desired keep
the rod parallel by fixing at each end'a pinion gearing into a stationary rack.
We fit one end of the rod to a boss at the top of a two-armed lever, one arm
having a stud placed in a curved slot in a bracket fixed to one of the end
frames or front rail of the loom, and the other arm carrying a swing lever
having a regulating stud placed in the slots of a double-slotted lever working
on a stud fixed to the; framework, the said double-slotted lever having an arm
worked by a tail or spindle on one of the sword arms. We also place the
regulating stud in the slot of the lever which works a rim wheel, or the
ordinary ratchet wheel of taking-up motions. As the slay sword moves to
and fro it gives motion by the tail or spindle to the double-slotted lever, and
also to the lever which works the taking-up wheel, and as the cloth increases
in diameter the regulating stud drops in the slots of the double-slotted lever
at a variable diminishing speed, in consequence of the stud on the first-
mentioned arm moving in the slotted curve fixed to the front rail or frame;

page_text: or instead of the double-slotted lever we attach a slot to one of the sword
arms for performing the same task. Or instead of fixing a stud on the first-
mentioned arm, and placing it in a stationary curved slot we make the arm
curved and pass it through an ordinary slot or guide; or we make the
curved slot in the arm itself, and pass the slot over a stationary stud, and in
those rim wheel or ratchet wheel levers which are worked by an eccentric on
the tappet shaft in connection with another lever operated upon by the
-increasing diameter of the cloth, we make the rim or ratchet wheel levers
curved instead of straight for the purpose of giving a variable-diminishing.
speed to the taking-up motion.
In another arrangement we place a bar or roller of wood or metal in
contact with the back of the cloth on the cloth beam, and cause the ends of
the bar or roller to be in contact with one end of a horizontal lever having its
other end working in a horizontally curved slot formed in a vertical slide to
which the swing lever is attached, so that as the cloth increases in diameter
the horizontally curved slot shall be depressed, and with it the slide, and also
'the swing lever, and thus give a variable diminishing motion to the taking-up
wheel and cloth beam. When the loom stops from the breakage or absence
of weft, it is frequently advisable to prevent the cloth from being taken up
until a few picks have been thrown across, and for this purpose we place in
guides at the front of one of the sword arms a horizontal slide having a
number of ratchet teeth at both sides. At the front of the sword arm there
is a ratchet or catch for acting on the teeth on one side of the slide, and the
teeth on the other side are provided with a spring catch. It is intended that
one end of this slide shall keep up the holding catch or the holding clip until
a few picks have been made, and be released by the catch on the sword arm
acting on as many teeth of the horizontal slide as there are picks to be made
before the taking-up commences.
