JOHN HENSHAW CANAVAN and MAX BAERLEIN, both of Salford, in the County
of Lancaster. IMPROVED DRYING APPARATUS TO BE USED IN CONNECTION
WITH PRINTING MACHINERY FOR WOVEN AND FELTED FABRICS AND FOR PAPER
STAINING."
It is customary to employ in connection with the printing machine an apparatus
known under the name of a drying and blanket frame for drying the material
after printing; also for drying the blanket and back cloth or grey which pass
through the printing machine along with the material to be printed.
In this blanket and drying framing the printed material as well as the blanket
and back cloth pass over, under, and round a series of rollers, and they are being
dried during that passage either by passing close to hollow chests heated by steam,
or by being subjected to the action of heated air; or in some cases also by passing
over hented surfaces in addition to the rollers named above.
Our improvement consists in using steam pipes, which we connect together
and supply with steam in a manner not hitherto employed in connection with
printing.
We employ on each side of the blanket or drying framing continuous steam
chests or tubes for supplying steam to a series of cross pipes, by preference of
copper or brass, which we insert into the side chambers by means of glands
and packing, so that they can freely expand or contract without causing leakage
at any point where escaping steam or water could damage the printed material.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Henshaw Canavan and Max Baerlein in the Great Seal
Patent Office on the 13th August 1880.
JOHN HENSHAW CANAVAN and MAX BAERLEIN, both of Salford, in the County
of Lancaster. "IMPROVED DRYING APPARATUS TO BE USED IN CONNECTION
WITH PRINTING MACHINERY FOR WOVEN AND FELTED FABRICS AND FOR PAPER
STAINING."
Our Invention consists in placing on each side of the blanket or drying framing
continuous chambers, steam chests, or tubes for supplying steam to a series of cross-
pipes, by preference of copper or brass, which we insert into the side chambers by
means of glands and packing, so that they can freely expand or contract without
causing leakage at any point where escaping steam or water could damage tho
printed material.
And in order that our Invention may be fully understood and readily carried
into effect, we will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Fig. 1 is an elevation in section of our improved drying apparatus. a is the back
cloth or grey; b is the endless blanket; and c is the fabric which is printed by the
engraved rollers d. The cross pipes forming part of our improved drying apparatus
are marked c, and they are supplied with steam by the continuous steam chests or
tubes marked f, shewn on an enlarged scalo in Figs. 2 and 3.
The fabric c after leaving the printing machine enters the drying apparatus, and
is carried over a number of guide rollers g and close to the heated cross pipes e, by
which it is thoroughly dried, and the fabric is drawn from the drying apparatus
by the rollers h, h. The endless blanket b travels continuously over the bowl of
the printing machine and over the rollers i. The back cloth or grey travels a
certain distance with the blanket, and then over the rollers, and after leaving the
drying apparatus it is formed again into a batch a¹. Fig. 2 is an end elevation,
and Fig. 3 is a cross section shewing on an cularged scale the continuous steam
chests or tubes f connected by the cross pipes c, which are secured by the glands m.
The packing in the glands prevents any escape of steam or hot water, and the cross
pipos e, which aro Hanged at one end, can expand or contract without causing
leakage. When steam is admitted to the steam chests or tubes fit circulates frecly
through the cross pipes e and produces great heat.
Having thus described the nature of our Invention, and shewn a manner of
performing the same, we wish it to be understood that we do not limit ourselves
to the exact details given; but what we claim is, the continuous steam chests or
tubes connected by cross pipes e, by means of glands or similar means, for the
purpose of drying the cloth, felt, paper, or other woven or felted fabric, substantially
as shown and described.
In witness whereof, we, the said John Henshaw Canavan and Max Baerlein,
have herounto set our hands and seals, this Third day of August, One
thousand eight hundred and eighty.
