PROVISIONAL SPECIFICATION left by the said William Bates and
Frederick Bates at the Office of the Commissioners of Patents, with
their Petition, on the 14th December 1867.
We, WILLIAM BATES and FREDERICK BATES, of the Firm of William
Bates and Son, of Sowerby Bridge, near Halifax, in the County of York,
Machine Makers and Millwrights, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN WASHING MACHINES KNOWN AS 'DOLLYS,'
WHICH IMPROVEMENTS RENDER SUCH MACHINES ALSO APPLICABLE FOR CRUSHING AND
FULLING FABRICS," to be as follows:-

page_text: 'This Invention relates to machines commonly known as "dollys" employed
in washing and scouring fabrics,and the improvements consist in the applica-
tion and use of an additional pair of squeezing rollers, betwixt which the
fabrics are caused to pass after having passed between the ordinary squeezing
rollers; also in the application of springs or weights to both these pairs of
rollers to regulate the pressure of the rollers upon the fabrics, as may be
required, whereby additional squeezing and washing effects are produced;
also in the application of a board or bar having slots or holes formed therein
for the fabric to pass through, which when any knotting or twisting or feltering
of the fabric-occurs will act upon the strap guide and immediately stop the
action of the machine. To render such machines applicable to crushing and
fulling fabrics an ordinary fulling trough with presser is placed between the
two pairs of rollers for the fabric to be worked or pushed through by the
action of the first pair of rollers in the usual manner, and a presser is also
applied atthe delivery side ofthe second pair of rollers which operates against
the bottom roller, producing additional crushing or fulling effects upon the
fabric.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Bates and Frederick Bates in the Great Seal
Patent Office on the 13th June 1808.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
BATES and FREDERICK BATES, of the Firm of William Bates and Son, of
Sowerby Bridge, near Halifax, in the County of York, Machine Makers and
Millwrights, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent,bearing date the Fourteenth day of December,in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for llersolf, Her heirs, and successors, give and grant unto us, the
said William Bates and Frederick Bates, Her special licenso that we, the
said William Bates and Frederick Bates, our executors, administrators,
and assigns, or such others as we, the said William Bates and Frederick
Bates, our executors, administrators, and assigus, should at any time
agree with, and no others, from time to time and at all times thereafter

page_text: during the term therein expressed, should and lawfully might make, use
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
WASHING MACHINES KNOWN AS 'DOLLYS, WHICH IMPROVEMENTS RENDER SUCH
MACHINES ALSO APPLICABLE FOR CRUSHING AND FULLING FABRICS," upon the condition
(amongst others) that we, the said William Bates and Frederick Bates, our
executors or administrators, by an instrument in writing under our, or
their, or one of our or their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said William Bates and Frederick Bates
do hereby declare the nature of our said Iuvention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement,thereof and accompanying Sheet of Drawings (that
is to say):
This Invention relates to machines commonly known as "dollys" employed
in washing and scouring fabrics, and the improvements consist in the applica-
tion and use of an additional pair of squeezing rollers, betwixt which the
fabrics are caused to pass after having passed between the ordinary squeezing
rollers; also in the application of springs or weights to both those pairs of
squeezing rollers to regulate the pressure of the rollers upou the fabrics as may
be required, whereby additional squeezing and washing effects are produced;
also in the application of a board or bar having slots or holes formed thereiu
for the fabric to pass through, which when any knotting or twisting or
feltering of the fabric occurs will act upon the strap guide and immediately
stop the action of the machine. To render such machines applicable to
crushing and fulling fabrics an ordinary fulling trough with pressure is placed
between the two pairs of rollers for the fabric to be worked or pushed through
by the action of the first pair of rollers in the usual manner, and a presser is
also applied at the delivery side of the second pair of rollers which operates
against the bottom roller producing additional crushing or fulling effects upon
the fabric.
This Invention will be readily understood by reference to the accompanying

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is the front elevation of a "Dolly," and Fig. 2 is a cross section of
the same taken through the line A, B, in Fig. 1, shewing our improvements
applied thereto.
Cand are the ordinary pair of squeezing rollers, and E and Fare the
additional pair of squeezing rollers. Both pairs of rollers are provided with
couch springs G and adjusting screws y, so that we can regulate the pressure
of the said rollers on the fabrics under operation as required. Or levers and
weights may beapplied for this purpose instead of the springs if desirable. El is
the board or bar with holes h formed therein for the fabrics to pass through,
which is hinged to the frame by the arms f, and attached to one end of this
board is a catch J,which takes into a lever K fixed on a shaft L, on which is
also fixed the strap guide M and two hand lovers N with a counterweight P.
When any knotting or feltering of the fabric takes place in its passage through
the machine the board will be lifted, and thereby remove the catch J from
its hold on the iever K,and the weight 1' will actuate the strap guide to throw
the strap from the fast pulley R to the loose one Sand consequently will stop
the machine. To render these machines applicable for crushing or fulling
fabrics we apply a trough 'T' betwixt the two pairs of rollers with a presser U
to act or press upon the fabrics as they are pushed forward by the action of
the ordinary rollers. Also we apply another presser V to act upon the tnbrics
as they issue or are delivered from the additional pairs of rollers pressing the
said fabrics against the bottom roller. When employed for washing or
scouring those pressers not being required may be suspended by the chains W
and X.
By this Invention the machine known as a "dolly" is not only improved
as applicable to its ordinary uses or purposes of washingand scouring, enabling
additional washing and scouring effects to be produced,, but is rendered
applicable or adaptable to be employed for the purposes of crushingaudfulling
fabrics,thus avoiding the costs of two machines and also saving the room and
other requirements for working them.
Having thus fully described the nature of our said Invention, and shewn
the mauner in which the same may be performed or carried into practical
effect, wo would have it understood that we do not confine ourselves to the
precise details of construction or arrangement of the several parts as herein
shown and described,as various modifications may be made therein; but what

page_text: we claim as of our Invention is, the application to and use in combination and
connection with "dollys" of parts or apparatus substantially as herein
described and shewn by the accompanying Sheet of Drawings.
In witness whereof, I, the said William Bates, for and on behalf of
myself and the said Frederick Bates, have hereunto set my hand and
seal, this Eleventh day of June, in the year of our Lord One thousand
eight hundred and sixty-eight.
William
