Year: 1871

page_text: LETTERS PATENT to William Carr Collier, of Salford, County of
Lancaster, Tin-plate Worker, for the Invention of "IMPROVEMENTS
IN THE CONSTRUCTION OF STEAM-DRYING CYLINDERS"
COMPLETE SPECIFICATION filed by the said William Carr Collier at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 23rd March 1871, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CARR COLLIER, of Salford, County of Lancaster, Tin-plate Worker, send
greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN-
THE CONSTRUCTION OF STEAM-DRYING CYLINDERS," and have petitioned Her
Majesty to grant unto me, my executors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn Declara-
tion that I am the true and first Inventor thereof..

page_text: NOW KNOW YE, that I, the said William Carr Collier, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed, in and by the
following statement:―
This Invention relates to the construction of steam-drying cylinders
in such a manner as to effectually eject the whole of the water formed
by the condensation of the steam in said cylinders, and consists in a
peculiar disposition of troughs or buckets between the blocks, so that as
the steam-drying cylinder revolves the said troughs or buckets drain or
eject the water from one division to another between the blocks until
the water arrives at the water outlet end of the cylinder, where it is
made to pass, or is conducted by means of a plain elbow pipe to the
ordinary nozzle or gland. By these means there is less or no risk of
collapse of cylinder through the accumulation of water suddenly con-
densing the steam or of accumulation of dirt, grease, and other matters
within the cylinder, which rapidly destroy or wear it out.

cylinder to keep it truc and in shape. In each division h, h², h³, between
the blocks e, e, e, commencing from the steam inlet end 8 of the
cylinder d.
I fix by means of solder, or other like and suitable means, trouglis
a, a, a, obliquely to the axis of the cylinder. These troughs are shewn
in section in Figs. 4 and 5 and in front elevation in Fig. I. On the
cylinder being made to revolve in either direction the trough a, a, in the
division scoops up the water in that division and conducts it into h³,
as shewn in the Drawing, and from thence it is conducted by the troughs
in ¹ into h, and so on until the water arrives into division ³, or the one
next the outlet w, where a trough b constructed partly in the ordinary
manner is used and shewn in section in Fig. 2, save that I employ
simply a plain elbow pipe c to conduct the water into the nozzle w from
the trough instead of using the chambers and other like contrivances
ordinarily applied. Instead of the water from the troughs a being con-
ducted through a perforation in the blocks e, e, the troughs may be
arranged to throw the water over the blocks by means of a simple tube
or other like contrivance.
Although I have shewn certain forms or shapes of troughs I do not
bind myself to the precise shapes delineated in the Drawings and
herein described, as the same may be varied without departing from
the principles of my Invention.
In witness whereof, I, the said William Carr Collier, have here-
unto set my hand and seal, this Twentieth day of March, in
the year of our Lord One thousand eight hundred and seventy-
one
Witness,
HENRY A. COLLIER,
Salford.
