Improvements in Ships' Water Closets.
SAMUEL KERSHAW, Plumber, 2, G. Barque Street, Barrow-in-Furness, do
hereby declare the nature of this invention to be as follows;-
The invention is in connexion with the discharge of the basin and takes the form
of a double cylindrical valve. The inner portion in the form of a piston or in the
form of a double sluice valve, with openings in outer caseing to meet openings in
cylinder or piston. The action of the closet handle by closeing one opening the
other.
Í, SAMUEL KERSHAW, Plumber, 2, G. Barque Street, Barrow-in-Furness, County
of Lancaster, 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:-
This invention relates to improvements in ships and other water closets, especially
connected with the discharge of the soil from the basin
The ships closets at present in use are worked by flaps swivels quadrants con-
necting cranks and shafts, which cause them to be liable to be soon out of repair.
In this invention all this machanism is done away with, and is simply worked
with two hollow metal cylinders being bored and turned to work smoothly one
inside the other, as described on drawing No. 1.
The outer cylinder is fixed in an earthenware shaft with cement and is a fixture,
with inlet from basin at A, and outlet to soil pipe at B. The inner cylinder slides
up and down and is described on drawing No. 1. After the closet has been used
by lifting the handle C the inner cylinder moves down and closes outlet B therby
opening inlet A. The contents of basin then discharge into inner cylinder
through D. By dropping the closet handle CA is closed and B is opened and the
contents of cylinder is discharged into soil pipe.
E is a diaphragm for rim of inner cylinder to rest on to ensure its being water-
tight.
This
F is an expansion ring to ensure basin being watertight when not in use.
improvement can be constructed in earthenware or in metals (iron or brass) as
required in differant classes of ships, can also be fixed in either perpendicular or
horizontal positions, and can be worked with either a slideing or rotary motion.

page_text: The invention is of so simple construction that the working parts can be taken to
peaces and examined in a few minutes.
No. 2 drawing shoes invention fixed in a horzontal position.
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
I claim is:
-
1. That there is no ships or other water closet of this description at present in
use, this being a complet new way of discharging the soil from the basin. And
the first water closet constructed on the above princeples.
2. That there is no internal obstruction to interfere with the free passage of the
soil from the basin to soil pipe.
3. Is its simplicity of action and ease of axcees in case of stoppage or repairs.
That it is not liable to get out of repair.
