the Commissioners of Patents, with his Petition, on the 1st November
1856.
I, BENJAMIN STOTT, of Salford, near Manchester, in the County of Lancaster,
Manager, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR PREPARING, SPINNING, AND DOUBLING.
COTTON, WOOL, FLAX, OR OTHER FIBROUS MATERIALS," to be as follows:-
My improvements in preparing, spinning, and doubling machines consist,
firstly, in employing a traversing drag, that is, giving a traversing motion to
the ordinary drag placed between the under sides of the bobbins and the
upper side of the copping rail; tho drag, either alone, or connected with a
plate, has a to-and-fro motion imparted to it to prevent the cloth or other
material from being worn in one place, and also to cause the drag upon the
bobbins to be more uniform. The cloth or plate is connected to a band, cord,
or chain passing over pulleys, the ends of the said band being fast to any
convenient part of the main framing; the motion of the copping rail gives
the traversing motion to the cloth or other material forming the drag.
Secondly, in the employment of a roving slubbing yarn or thread breaker, a
series of which, corresponding with the number of flyers, is placed at the back
of the rollers. Each breaker breaks the roving yarn or thread close to the
back of the rollers if it has been previously broken or snarled in front,
thereby preventing the roving yarn or thread from passing to the rollers, from

page_text: winding on the rollers or clearers, flying about catching other yarns, and also
from one broken end injuring or breaking others, thus obviating the well-
known evil of catched ends, or spoiled rovings, yarns, or threads.
These improvements will be understood by reference to the accompanying
outline Drawing, in which Fig. 1 is a plan, and Fig. 2 a front view, of part of
a machine to which a drag is applied, having one of my modes of traversing
the same, represents the copping rail, upon which is the drag b, either
singly or attached to a plate. A cord, band, or chain c is attached either to
the plate or drag, and is made to pass over the pulleys d, and their ends fixed
to any convenient part of the framing as at e, the motion of the copping rail
giving the desired traverse.
Figure 3 is part of a preparing, spinning, or doubling machine, to which
one arrangement of breaker is applied. f represent the main framing; g, the
flyer; h, the rollers; and k, the roving, yarn, or thread, which passes from the
creel through an eye in the tumbler or weighted beam 1, supported on the shaft
or bearing m. Near the top of the flyer the roving, yarn, or thread is sup-
ported by one end of a lever n, having its fulcrum at o, and its other end
pressing against the lower arm of the beam or tumbler 1, maintaining it in its
position for working when no breakage or snarling takes place. On the
shaft m is the plug or wedge p, the point of which is in the same radius as
the eye in the tumbler. When the tension or pressure of the roving, yarn,
or thread leaves the end of the lever n, one side of the lever rises and the
other falls down, taking off the support to the tumbler, which also falls down.
upon the plug or wedge and breaks the roving, yarn, or thread.
