PROVISIONAL SPECIFICATION.
Improvements in Machinery for Washing Blankets Used on Printing
or Padding Machines.
We Ross GEMMELL, Calico Printer, and FREDERICK BUXTON, Mechanic, both
of the Bingswood Print Works, Whaley Bridge, near Stockport, in the County
of Derby do hereby declare the nature of this invention to be as follows :—
The object of this invention is to construct apparatus for the more efficient
washing of "leatherine” or other blankets used on printing or padding machines.
Our improved machine consists mainly of a number of transverse brushes, or
squeegees," or a combination of both brushes and "squeegees," fixed to and
running with endless chains, and working against the side of the blanket which is
to be washed.
66
The chains are arranged to move vertically (or nearly so) and to draw the
brushes or squeegees downwards against the blanket, and so to brush or sweep the
dirt from the same into a suitable receptacle or receptacles beneath.
We employ two or more sets of chains and brushes or squeegees, but in the case
of brushes being used the last set of chains should carry squeegees to dry the
Burface of the blanket, and each set of brushes or squeegees excepting this last is
provided with a suitable perforated pipo for spraying the blanket with water or
other cleansing fluid.
Each pair or set of chains is provided with a suitable tightening pulley and they,
or the brushes or squeegees, also run in contact with suitable curved adjustable
guiding plates bearing against the inner surfaces thereof which so deflect the
brushes or squeegees and the blanket, that the former will act with greater
efficiency against the face of the blanket. The latter passes around suitable tension
and guide pulleys to keep it tight and bring the surface to be cleansed into contact
with the downwardly moving brushes or squoegees.
In most cases we propose to drive this apparatus independently, and not from the
printing or padding machine as usual, so that although the endless length of blanket
passes through the washing apparatus and the printing or padding machine, the
blanket can be washed while the latter is stopped.
Dated this 16th day of October 1895.

Improvements in Machinery for Washing Blankets Used on Printing
or Padding Machines.
We Ross GEMMell, Calico Printer, and FrederioK BUXTON Mochanio, both
of the Bingswood Print Works, Whaley Bridge, near Stockport, in the County of
Derby, 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 to construct apparatus for the moro efficient
washing of “leatherine ” or other blaukots used on printing or padding machines.

page_text: Our improved machine consists mainly of a number of transverse brushes or
squeegees or their equivalent fixed to and running with endless chains, and working
against the side of the blanket which is to bo washed.
The chains are arranged to move vertically (or nearly so) and to draw tho
brushes (by preference downwards) against the blanket and so to brush or sweep
the dirt from the same into a suitable receptacle or receptacles beneath.
We may employ one two or more sets of chains and brushes and each set of
brushes is provided with a suitable perforated pipe for spraying the blanket with
water or other cleansing fluid. The last set of brushes squeegees or their oquivalent
may however be used to dry the surface of the blanket.
Each pair or set of chains is provided with a suitable tightening pulloy and they
or the brushes or their equivalent also run in contact with suitable curved adjustable
guiding plates bearing against the inner surface thereof which so deflect the brushes
and the blanket, that the former will act with greater efficiency against the face
of the blanket. The latter passes around suitable tension and guide rollers to
keep it tight and bring the surface to be cleansed iuto contact with the moring
brushes.
The annexed drawing illustrates one way of carrying our invention into
practice.
a are the transverse brushes fixed to and running with endless chains ỗ, and
working ngainst the side of the blanket a which is to be washed.
The chains are arranged as shewn to move vertically (or nearly so) and to draw
the brushes a downwards against the blanket e, and so to brush or sweep the dirt
from the same into a suitablo receptacle d.
Each set of brushes a is provided with a suitable perforated pipe e for spraying
the blanket o with water or other cleansing fluid and we prefer to use a rotary
drying brush as seen at a to dry the blanket c as it leaves the machino.
Each pair or set of chains b is provided with a suitable tightening pulley or its
equivalent and the said chains (or the brushes) also run in contact with suitable
curved adjustable guiding platos bearing against the inner surfaces thereof which
so deflect the brushes a and the blanket c, that the former will act with greater
efficiency against the face of the blanket c. The latter passes around suitable
tension and guide rollers i to keep it tight and bring the surface to be cleansed into
contact with the downwardly moving brushes a.
The apparatus may be driven directly from the printing machine in connection
with which it is worked, or the endless chains carrying the brushes may be driven
independently as from a line shaft, the latter arrangement providing for the
thorough cleansing of the blanket whilst the printing machine is slowly turning
round or stopped.
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 combination of endless chains provided with brushes or their equivalents
drawn by the motion of the chains against the surface of the blanket to be washed,
with perforated spray pipes to cleanse the said, blanket, substantially as hereinbofore
