both of Accrington, in the County of Lancaster. 'IMPROVEMENTS IN SIZING
MACHINES."
"
This Invention relates to the roller or rollers employed for pressing the yarn or
warp as wound upon the finished or sized beam, and the object of the Invention
is the use of a roller or rollers, so constructed or arranged as to ensure the pressing
of the entire width of the yarn or warp whatever the width of the beam, that is to
say, the roller or rollers are adjustable to varying widths of beam.
According to this Invention, where we employ but one roller, the latter is made
in two lengths and mounted upon a shaft or axis, one portion or length being loose
on the axis; the joint or part of contact between the two portions constituting the
said rollers are oblique or inclined, so that the frictional contact between the roller
and beam or the yarn thereon causes the parts of the roller to diverge, and so fill
in the whole space or length of beam between the flanges thereof.
Where the variation of distance between the flanges is considerable we employ
two rollers; these are carried upon anti friction rollers of varying diameters, or they
are set with the line of their axis obliquely so as to impart a tendency to move
laterally as well as to rotate by contact with the yarn on the beam; or the rollers
are made slightly taper so as to ensure the rollers (right and left) filling in the
space between the flanges. The rollers are made of such lengths as to overlap
considerably each other, providing for considerable variation of length between the
flanges.

At A is the warp wound in the ordinary manner upon the beam B; C is the
presser roller carried by and caused to rotate upon the antifriction rollers D, D, by
frictional contact of the warp A. The rollers D, D, are carried by the arms E, E,
the bosses F, F, of which receive a square shaft G, on the end of which is
a lever and balance weight H, by means of which the pressure of the roller C upon
the yarn A may be regulated, as desired. Referring now to the roller C, the
improvements in which constitute this Invention, it will be seen on reference to the
larger or detail Figures 3, 4, and 5, that the main length of the roller is hollow
and has attached to one end a stud J, and the end K forms (by preference) double
or right and left handed incline or oblique surfaces M, M, as shewn, the shorter
end having corresponding oblique surfaces, so that the frictional contact of the
warp A upon the shorter and lighter end C₁ (which end is made slightly smaller
in diameter) turns the latter upon its stud J. The surfaces M, M, then cause a
divergence or end wise elongation, as shewn at Fig. 4, thus causing the roller C to
fill in the whole width between the flanges P, P, and ensuring the rolling and
pressing the whole width of the warp, for although the opening or space R, Fig. 4,
leaves during a part of the revolution of the roller the yarn unpressed, the
difference in diameter of the presser roller of the yarn beam B and yarn thereon
prevents the space R on the next revolution of the roller and beam coming again
opposite the portion of yarn unpressed. The true angle or incline of the oblique
surfaces is clearly shewn at Figs. 3 and 3, taking Fig. 3 as a view looking down
on the roller, and Fig. 3º as a view from the underside of the roller; the other
views illustrate a roller in which a spiral spring S is used for expanding the shorter
end C¹ of the roller, and having a trigger or holding device for preventing the

flanges P, P, whereon the pressure of the roller and beam upon the incline or
oblique surfaces. M, Fig. 6, will cause the latter and its holding catch T to turn
upon the stud pin W, so withdrawing the end of the catch T from or out of a
recess cut or formed in the stud J thereon, permitting the spring S to expand,
forcing the ends C₁ of the roller lengthwise, and at the same time folding the
incline M into the position shewn at Fig. 7. Y is a spring for holding down the
catch T in the recess prior to the action of the spring S and expansion of the roller
taking place.
Having thus fully described the nature nature and object of this our said
Invention, together in manner which the same is to be or may be performed, we
would have it understood that what we claim as our Invention is,-
Firstly. We claim the construction, application, and use of presser roller for
purpose aforesaid, expanded or elongated by incline or oblique surfaces, such
as M, M, as herein described and illustrated by Drawings, Figures 3, 3ª, 4, and 5.
Secondly. The use of the incline or oblique holding catch M, T, combined with
spring Y, substantially as herein described and illustrated by Drawings.
In witness whereof, we, the said Edmund Tweedale and Samuel Tweedale,
have hereunto set our hands and seals, this Twelvth day of August, in the
year of our Lord One thousand eight hundred and eighty one.
