We WALTER ROBERTSHAW of Allerton Mills, Allerton near Bradford in the..
County of York Spinner and Manufacturer, and EBER COCKCROFT, of the same
place, Combing. Overlooker, do hereby declare the nature of this, invention to be
as follows:-
This invention relates to certain improvements in the apparatus employed for
delivering the wool or other fibre from the washing bowl to the squeezing rollers;
and has for its object, the feeding of the fibre to the rollers in such a manner; that
"stringing and matting "-are prevented, and the possibility of choaking the rollers
greatly reduced.
We accomplish the above object by placing near the top squeezing roller, a
rotating roller across the machine and, mounting on the same an apron which is in
contact with the bottom squeezing roller, and kept stretched by a bar that is.
secured to two levers provided with adjustable weights.
The forks carry the fibre through the bowl as hitherto, but the last fork is so
arranged, that it delivers the fibre into the "nip" between the bottom roller and
apron; and by the apron being in contact with the roller and moving in the same
direction, the fibre is carried upwards and passed through the squeezing rollers in
an open state, with more regularity than when fed on to an inclined apron,
thereby preventing stringing and matting, and reducing the liability of the rollers
choaking.

We, WALTER ROBERTSHAW, of Allerton Mills, Allerton, near Bradford in the
County of York, Spinner and Manufacturer, and EBER COCKROFT, of the same
place, Combing Overlooker, 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:—
The object of this invention is in the delivery of wool or other fibre from the
washing bowl to the squeezing rollers, in such a manner that "stringing" and
"matting" are prevented, and the possibility of choking the rollers greatly
reduced.
We accomplish the above object by placing near the top squeezing roller a
rotating roller across the machine and mounting on the same an apron which is in
contact with the bottom squeezing roller, and kept stretched by a bar that is
secured to two levers provided with adjustable weights.
The forks carry the fibre through the bowl as hitherto, but the last fork is so
arranged that it delivers the wool or other fibre into the "nip" between the
bottom squeezing roller and apron, and by the apron being in contact with the
roller and moving in the same direction, the wool or fibre is carried upwards and
passed through the squeezing rollers in an open state and with more regularity
than when fed on to an ordinary inclined apron, thereby preventing™" stringing "
and "matting" and at the same time reducing the liability of the squeezing rollers
choking.
"
In order that this invention may be better understood, we will further describe
the same by making reference to the accompanying drawings in which Fig. 1
represents a longitudinal section through such portions of a wool washing machine
as are necessary to illustrate the invention, Fig. 2 is a plan of the same, Fig. 3 is
a cross section through line a. b. with the feeding forks removed, and Fig. 4 is an
enlarged sectional detail of the squeezing rollers and apron. In all the figures,
similar letters indicate similar parts where they appear."
The frame is indicated by the letter A to which are mounted the two squeezing
rollers C and D in the ordinary manner; near to the top squeezing roller C we
secure a rotating roller E across the machine, and mount on the same an apron F
which is in contact with the bottom squeezing roller D and is kept stretched by
bar G; and to the latter we attach two levers H and H2 supported by pins as
fulcrums and provided with two adjustable weights J and J¹, thus keeping the
apron F in close proximity with the bottom squeezing roller D.
The wool or fibre is carried through the bowl in the ordinary manner but the
last fork K is so constructed that it delivers the wool or fibre into the "nip" N
between the bottom squeezing roller D and the revolving apron F travelling in the
same direction, as indicated by the curved arrows, and being in contact with each
other, the wool or fibre is carried upwards and passed through the squeezing
rollers C and D in an open state and with more regularity than when fed on to an

page_text: ordinary inclined apron, thereby preventing "stringing" and "matting" and at the
same time greatly reducing the liability of the squeezing rollers choking as is the
case with the inclined apron.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:-
The squeezing rollers C and D of a wool washing machine combined with the
additional roller E and apron F substantially in the manner and for the purpose
set forth.
