PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Washing and Oleansing Calico
Printers' Blanketing.
We WILLIE HADFIELD of Furness Vale, in the County of Chester, Colourist,
JOSEPH JOHNSON SUMNER of the same place, Mechanic, and HENRY HADFIELD
also of the same place, Manager, do hereby declare the nature of this invention to
be as follows:-
Our said invention relates to improvements upon a former invention for which
we have made application for Her Majesty's Letters Patent No. 12772 of 1894.
The present improvement refers to a more compact and economical construction
and arrangement of parts than those indicated in the Complete Specification of our
said former invention. Under the present design we carry the longitudinal recipro-
cating brushes which oscillate in the direction of traverse of the blanketing on
arms or in a frame pivotted on the shaft of the roller around which the blanketing
is passed. This frame or set of arms with its brushes is preferably contained
entirely within the trough or receptacle supporting and containing the moving
parts of the apparatus.
Thus the outer side bars, levers, bearings and other parts necessitated by our
former arrangement are entirely done away with and the construction is greatly
cheapened and simplified. The reciprocating brushes are arranged towards one
side of the roller, and we bring the drying brush against the blanketing on the free
side of the said roller instead of applying the said drying brush in conjunction with
a separate and independent roller as before. This enables us to shorten the
apparatus and erect the blanket washer within comparatively small limits. The
arrangement as a whole presents very material advantages in the shape of cheapness,
simplicity and compactness.
The reciprocating brush frame or the pivotted arms carrying the brushes may be
oscillated by a quick running excentric or by any other suitable means for giving
the required motion. The usual spurt pipes are used in conjunction with the said
Oscillating brushes.

Improvements in Apparatus for Washing and Cleansing Calico
Printers' Blanketing.
We WILLIE HADFIELD of Furness Vale, in the County of Chester, Colourist,
JOSEPH JOHNSON SUMNER of the same place, Mechanic, and HENRY HADFIELD
also of the same place, Manager, 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 said invention relates to improvements upon a former invention for which we
have obtained Her Majesty's Letters Patent No. 12772 of 1894.

page_text: The present improvement refers to a more compact and economical construction
and arrangement of parts than those indicated in the Complete Specification of our
said former invention.
Under the present design we carry the longitudinal reciprocating brushes which
oscillate in the direction of traverse of the blanketing, on arms or in a frame
pivotted on the shaft of the roller around which the blanketing is passed.
This frame or set of arms with its brushes is preferably contained entirely
within the trough or receptacle supporting and containing the moving parts of the
apparatus. Thus the outer side bars, levers, bearings and other parts necessitated
by our former arrangement are entirely done away with and the construction is
greatly simplified.
The reciprocating brushes are arranged towards one side of the roller, and we
bring the drying brush against the blanketing on the free side of the said roller
instead of applying the said drying brush in conjunction with a separate and
independent roller as before. This enables us to shorten the apparatus and. erect
the blanket washer within comparatively small limits.
The arrangement as a whole presents very material advantages in the shape of
simplicity and compactness.
The reciprocating brush frame or the pivotted arms carrying the brushes may be
oscillated by a quick running excentric or by any other suitable means for giving
the required motion. The usual spurt pipes are used in conjunction with the said
oscillating brushes.
The improved construction and arrangement constituting our invention will he
best understood from a reference to the annexed sheet of, illustrative drawings.
Fig. 1 is an end. elevation of our improved blanket washer.
Fig. 2 is a front elevation.
Fig. 3 is a vertical section of Fig. 1.
Fig. 4 is a plan.view.
The machine consists of two side frames a, a connected by the curved bottom, b
the whole constituting the trough and sides supporting and containing the moving
parts of the apparatus. Upon the sides a a we mount brackets cc which carry the
guiding rollers e, e, e the other guiding rollers.e', e' being carried by the lower part
of the framing. Bearing brackets on the sides a a support the shaft d of the
central backing roller f. A pulley y on the end of the shaft d takes a driving belt
by which motion is imparted to the roller. Other bearing brackets h carry a
shaft i upon which are fixed two excentrics fitted with excentric straps which are
connected by connecting rods k k with bosses mounted loosely on the shaft d and
which are formed with jaws to receive the ends of the connecting rods. From the
bosses there radiate arms m for example three on each side. Upou, these. arms.m
we loosely mount tubular sleeves n screwed at the ends so as to take the jamb
nuts n².
Between the jamb nuts n we bind and support the ends of the metallic girder
shaped backs. o which, carry the brushes p. Between the ends of the tubular
sleeves n and the outer ends of the arms m we place springs q which are compressed
between the ends of the sleeves n and the jamb nuts and washers on the ends of
the arms.
The bristles of the brush p are therefore held with an adjustable elastic
pressure against the central roller for against the blanketings which passes partly
around. the roller. As the blanketing is usually more dirty at the sides than in the
centre we make each brush, p wider at the ends than at the centre as seen most
clearly at Fig. 2. Thus a greater amount of brush or bristle surface is brought to
bear at the edges of the blanketing than at the centre. The arrangement we have
described constitutes a concentrically rocking frame pivotted upon tlie shaft d of
the central roller f. The arms m and other parts. of the frame are all contained
within the trough receptacle and between the side frames so that the triple brush
frame reciprocates without being interfered with by the sides. The shaft i is
.rotated by a belt, which passes partly around. the pulley, at one end of the shaft
and the excentrics j;are thus, driven, so as to reciprocate the brushes. The opposite

page_text: end of the shaft carries another pulley u which is connected by a belt with a
smaller pulley upon one end of a shaft w which shaft carries a revolvable drying
brush, similar to the drying brush described in the Specification of our said
former Patent. By the described arrangement the drying brush x is revolved at a
rapid rate, and its bearing brackets are adjust ed towards the central roller f by
adjusting screws y', so that the drying brush can be made to bear with any
required degree of pressure upon the blanketing s as it passes around the roller f.
The central roller fthus presents the requisite backing surface to the action of the
three concentrically reciprocating scrubbing brushes p, p, p and also to the action
of the revolving drying brush .c. We thus obtain a very compact and economical
arrangement. The progress of the blanketing s through the apparatus is indicated
by the arrows in Figs. 1 and 3. Spurt pipes z are arranged at suitable points to
supply water or detergents to the scrubbing brushes p, p, p. The liquid supplied
by the spurt pipes falls into the trough and is drained off by the outlet *. The
face only of the blanketing s is wet, the back being preserved in a dry condition.
The fast running drying brush so effectually removes the moisture from the face
of the blanketing s as it leaves the central roller, that the usual squeezing rollers
are dispensed with, and the blanketing is dried with the aid of considerably fewer
drying cylinders than is ordinarily necessary.
The number of the concentrically reciprocated brushes p might be varied, and
instead of applying the drying brush to the blanketing in the indicated
position i.e. against the central roller fit might be applied to the blanketing at
any position suitable in the apparatus after the blanketing leaves the central
roller.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is.
1. The general arrangement construction and combination of parts constituting
our improved apparatus for washing and cleansing calico printers' blanketing
substantially as described and as indicated in the drawings.
2. In apparatus for washing and cleansing calico printers' blanketing, carrying
the scrubbing brushes, which oscillate in the direction of traverse of the blanketing,
on arms or supports or in a frame hung or centred upon or pivotted to, the shaft of
the central backing roller f the said arms or supports or the frame being connected
to excentrics or other suitable operating means so that the said scrubbing brushes
reciprocate concentrically with the said central roller and against the blanketing as
it passes around the roller for the purposes and substantially as described and
shown.
3. In apparatus of the indicated nature the combination of the central backing
roller for taking the blanketing round, with the scrubbing brushes carried ou
parts pivotted to the axis of the roller or so as to reciprocate concentrically there-
with, and the drying brush operating upon the blanketing against the central
roller f, substantially as described and shown.
