Improvements in or Applicable to Yarn Sizing Machinery.
We JAMES SMITH SUTOLIFFE and JAMES SUTCLIFFE SMITH of the Britannia Mill,
Bacup, in the County of Lancaster, Manufacturers, do hereby declare the nature of
this Invention to be as follows:-
Our Invention relates principally to warp sizing machinery. In such machines the
warp is passed into a cistern containing size which is fed into the cistern and is
boiled or heated as it is introduced steam being passed directly into what is some-
times termed the size box. We have found in practice that when the warps have
varied in substance or in the number of ends so as to take up less or more size the
operation has not been perfectly regular. As the heavier warps have absorbed a larger
quantity of size in a given time than the lighter warps the supply of size and steam
which would suit one weight of warp would not properly suit another so that the size
has varied in weight or character. To enable the operation to be conducted with more
regularity of result is the object of our invention. To this end we provide suitable
means whereby the speed of rotation of the squeezing rollers can be readily varied in
order that the speed of traverse of the warp through the machine may be so regulated
as that as near as may be warps absorbing more or less of the size shall still with-
draw from the cistern a similar weight of size in a corresponding period of time. For
the purpose of our invention we transmit the motion to the said rollers by means of a
pair of cone drums and we provide means whereby the driving belts can be readily
shifted upon the said drums so as to vary the speed of the said rollers as may be
desirable. In the arrangement which we have devised for the purpose the two belt
guides are arranged to be moved in unison by means of two screws which are con-
nected by means of bevel wheels with a connecting shaft. Suitable means are provided
whereby the said connecting shaft may be turned so as to shift the belt in one direc-
tion or the other upon the drums. We do not confine ourselves to the use of screws
for moving the belt guides nor to the use of cone drums as a disc and sliding friction
pinion might be used or if fine adjustments were not considered to be necessary
stepped cones might take the places of the cone drums but we prefer the latter.
advantage attending the use of our invention and not previously mentioned is that
heavy warps would be allowed a longer time for the absorption of size.

page_text: We JAMES SMITH SUTCLIFFE and JAMES SUTCLIFFE SMITH of the Britannia Mill,
Bacup, in the County of Lancaster, Manufacturers, do hereby declare the nature of
this Invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
Drawings:-
Our Invention relates principally to warp sizing machinery. In such machines the
warp is passed into a trough or cistern containing size which is fed into the trough
and is boiled or heated as it is introduced. It is of importance that the size shall be fed
to the machine with regularity so as to maintain uniformity in the density of the size
in the trough but we have found in practice that when the warps have varied in
substance or in the number of ends so as to take up less or more size of a given
density the operation has not been perfectly regular. As the heavier warps have
absorbed a larger quantity of size in a given time than the lighter warps the supply
of size and steam which would suit one weight of warp would not properly suit another
so that the size has varied in weight or character. To enable the operation to be
conducted with more regularity of result is the object of our invention.
To this end
we provide suitable means whereby the speed of rotation of the squeezing rollers can
be readily varied in order that the speed of traverse of the warp through the
machine may be so regulated as that as near as may be, warps absorbing more or
less of the size shall still withdraw from the trough a similar weight of size in a corre-
ponding period of time. For the purposes of our invention we transmit the motion to
the said rollers by means of a pair of cone drums and we provide means whereby the
driving belt or belts can be readily shifted upon the said drums so as to vary the speed
of the said rollers as may be desirable. The manner in which we carry our inven-
tion into effect will be most clearly understood when our invention is described with
reference to the two accompanying drawings. In the said drawings Fig. 1 represents
a plan view of the improved driving mechanism for warp sizing machinery and Fig. 2
represents the same parts in elevation. In the said Figs. A represents a warp sizing
machine and B the line shaft from which the driving power is obtained. As the
sizing machine may be of any ordinary or suitable formation the details of its con-
struction do not appear in the drawings. In the two Figs. c. c¹ are the aforesaid cone
drums which we interpose between the line shaft B and the sizing machine. The
shafts of the said cone drums are mounted to revolve in suitable hangers or bearings
and upon the shaft of the cone c is fixed a pulley which is connected by means of a
belt d with a driving-pulley which is fixed upon the line shaft. The cone c drives the
cone c by means of a belt e. Upon the shaft of the cone c¹ is fixed a pulley f which
gives motion by means of a belt to the fast and loose pullies h which are upon the
roller shaft of the sizing machine. It will be seen that when the belt e is in an
intermediate position upon the cones as shown in the drawings the speed of the sizing
machine rollers will not be affected by the cones but if the said belt is shifted in the

direction indicated by the arrow the speed of the said rollers will be increased, a
decrease in speed resulting from the shifting of the belt in a direction contrary to that
indicated by the arrow. The shifting of the belt is effected by means of the strap
forks which are carried by blocks kk which slide upon screw shafts II and arc
provided with nuts which engage with the screw threads of the said shafts. The two screw
shafts are coupled together by means of the connecting shaft m and bevel gearing
A vertical shaft is connected by means of bevel gearing with the shaft m and is
provided with a hand wheel or handle p which is conveniently situated for the attendant
upon the sizing machine to turn the shaft o whenever desirable. It will be clearly
seen that when the shaft o is turned, movement will be communicated to the two screw
shafts whereby the strap forks will be moved in unison and the belt will be shifted
along the cone drums in either direction as required and as determined by the
direction in which the shaft o is rotated. In practice the attendant would so regulate
the speed of the squeezing rollers as that the size would be withdrawn from the
machine at a regular rate as near as might be, turning the handle p to reduce the
speed when the heavier warps would be passing through the machine and to increase
the speed when the lighter warp would be passing through. We do not confine our-
selves to the use of screws for inoving the belt guides nor to the use of the shaft o
and handle P to turn the said screws nor to the use of cone drums as a disc and sliding
friction pinion might be used. An advantage attending the use of our invention and
not previously mentioned is that heavy warps would be allowed a longer time for the
absorption of size.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
claim is
-
(1) The combination of parts constituting the driving apparatus for warp sizing
machines substantially as and for the purposes set forth and indicated hereinbefore
and in and by the accompanying drawings.
(2) In the driving of Warp Sizing machines the employment of cone drums or
other suitable variable speed motion interposed between the line shafting and the
machine in order that the speed of traverse of the warp may be regulated at will
substantially as and for the purpose set forth.
