IMPROVED MEANS FOR PREVENTING CONDENSATION ON THE WALLS OF LIVING SPACES AND OTHER INTERNAL SURFACES OF IRON SHIPS
Year: 1884

page_text: I ALFRED AURELIUS CLARK of N° 7 Caledonian Road, King's Cross in the
County of Middlesex, Varnish and Color Manufacturer, do hereby declare the
nature of my invention for IMPROVED MEANS FOR PREVENTING CONDENSATION
ON THE WALLS OF LIVING SPACES AND OTHER INTERNAL SURFACES OF IRON SHIPS,
to be as follows:-
-
It is well known to officers and seamen engaged in navigating iron ships that
great inconvenience arises from the condensation of moisture upon the internal
metallic surfaces of such vessels.
Attempts have been made with some success to avoid this inconvenience but they
have resulted in imparting unsightliness to the walls of the officers and seamens
quarters and have not afforded the means of producing a smooth and even surface
to the metal walls.
By my invention I am not only enabled to coat metallic surfaces in a manner
that will prevent condensation and the running of moisture down the walls but
also to apply such a thickness of coating as will cover any irregularities in the
structure and that at a comparatively small cost.
In carrying out my invention I first carefully clean the metallic surfaces to be
coated and then apply thereto a varnish impervious to moisture. That which I
prefer to employ is a mixture of Copal varnish and Zinc white but equivalent
varnishes may be employed. This mixture I apply by a brush to the cleaned
metallic surfaces and when the varnish has partially dried or come to a tacky state
I apply thereto in any convenient manner powdered flock such as that used in the
manufacture of paper hangings. This I pay over with a second layer of varnish
and coat the same with flock as before and if requisite I repeat this treatment three
or more times until the required smooth finish is obtained The surface thus pro-
duced may be ornamented by stencilling a pattern thereon or other means of
ornamentation which the taste of the decorator may suggest may be employed.

I ALFRED AURELIUS CLARK of No 7 Caledonian Road Kings Cross in the
County of Middlesex, Varnish and Color Manufacturer do hereby declare the
nature of my invention for "IMPROVED MEANS FOR PREVENTING CONDENSATION
ON THE WALLS OF LIVING SPACES AND OTHER INTERNAL BURFACES OF IRON SHIPS,"
"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
It is well known to Officers and seamen engaged in navigating iron ships, that
great inconvenience arises from the condensation of moisture upon the internal
metallic surfaces of such vessels.
Attempts have been made with some success to avoid this inconvenience, but
they have resulted in imparting unsightliness to the walls of the officers' and
seamen's quarters, and have not afforded the means of producing a smooth or oven
surface to the metal walls. By my invention I am not only enabled to coat the
said metallic surfaces in a manner that will prevent condensation and the running
of moisture down the walls, but also to apply such a thickness of coating as will
serve to fill up any surface irregularities in the structure due to the lapping of the
plates and the occurrence of the lines of rivet heads, and that at a comparatively
small cost.
In carrying out my invention I first carefully clean the metallic surfaces to be
coated, the presence of rust or grease being detrimental to the proper application
of my process. To the cleaned metallic surfaces I apply a varnish impervious to
moisture, that which I prefer_being_a_mixture of copal varnish and zinc white, but
equivalent varnishes may be employed.
The proportions which have been found to answer well are 4 lbs of finely ground
zinc white, in its dry state, to one gallon of copal varnish of medium thickness.
This mixture I apply by a brush to the cleaned metallic surfaces, and when the
varnish has partially dried or come to a tacky state, I apply thereto, in any con-
venient manner, ground woollen fibres or powdered flock such as that used in the
manufacture of paper hangings, but in its natural or undyed state. This I pay
over with a second layer of varnish, and coat the same with flock as before, and if
requisite I repeat this treatment three or more times until the required even finish
is obtained. The surface thus obtained may be ornamented by stencilling a pattern
thereon, or other means of ornamentation, which the taste of the decorator may
suggest, may be employed.
My object in combining zinc white with the varnish, and in using uncolored
flock or ground woollen fibre, is to obtain a light tone for the walls, that being the
most agreeable where the apertures for the admission of light are necessarily
restricted in size. It will however be understood that I do not limit myself to the
use of this pigment, or to undyed flock, but propose to use any tint which taste or
convenience dictate.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
1 claim is
Applying to the internal surfaces of iron ships, a coating as described, whereby
the inconvenience due to the condensation and running down, in streams, of the
moisture of the air, is prevented.
