PROVISIONAL SPECIFICATION.
Improvements in Ships' Water Closets.
We, EDWIN JAMES PRESTON, of the firm of J. Stone & Co., of Deptford, in the
County of Kent, Engineers, and EDWIN WILLIAM DE RUSETT, of 2, Fell Road,
Croydon, in the County of Surrey, Civil Engineer, do hereby declare the nature of
this Invention, to be as follows:-
The object of our invention is to improve the construction of water-closets for ships'
use so as to render them more cleanly, or for better appearance and more suitable
generally for first class passenger steamers.
Our improvements are applicable to single and double valve types. According to
our invention we arrange the soil outlet in the lower front part of the pan with valve
underneath, the space above which normally contains water from the after flush
cistern. The pan is made of earthenware. The mechanism for working the valves is
all at the back and out of sight, but open to inspection, while the lower part of the
closet is enclosed at the front and on the sides by an earthenware foot or foundation.
We thus do away entirely with all wood work for casing, and all that is seen from
the front, besides the handle and weighted pull up, is the earthenware pan and
foundation-both being plain or with any desired ornamentation.
The supply valve is arranged partly within the flushing box whereby we effect a
saving in weight and space. The supply valve is sometimes fitted with a regulating
pipe for governing the flow of water into the basin. We also effect a saving of
weight and space by combining the after-fiush and the overflow.
The wooden top of the closet is hinged so as to lift up when the closet is to be used
as an urinal.

Improvements in Ships' Water Closets.
We EDWIN JAMES PRESTON of the firm of J. Stone & Co. of Deptford in the
County of Kent Engineers, and EDWIN WILLIAM DE RUSETT of 2 Fell Road,
Croydon, in the County of Surrey, Civil Engineer, 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 our invention is to improve the construction of water closets for ships'
use so as to render them more cleanly, of far better appearance and more suitable
generally for first class passenger steamers.
Our improvements are applicable to single and double valve types. According to
our invention we arrange the soil outlet in the lower front part of the pan with valve
underneath, the space above which normally contains water from the flushing cistern.
The pan is generally made of earthenware. The mechanism for working the valves is
practically all at the back and when the closet is fitted with a seating is out of sight
but open to inspection, while the lower part of the closet is enclosed at the front
and on the sides by an earthenware foot or foundation. We thus do away entirely
with all woodwork for casing, and all that is seen from the front, besides the handle
and weighted pull up, is the earthenware pan and foundations both being plain or with
any desired ornamentation.
The supply valve is arranged partly within the flushing box whereby we effect a
saving in weight and space. The supply valve is sometimes fitted with a regulating

page_text: pipe or valve for governing the flow of water into the basin under varying pressures.
We also effect a saving of weight and space by combining the after flush and the
over flow.
The wooden top of the closet is hinged so as to lift up when the closet is be used
as an urinal.
Figure 1 of the accompanying drawings is a vertical longitudinal section through
a single valve water closet of our improved construction. Figure 2 part front view
and part transverse section through same. Figure 3 a side view and Figure 4 a
plan. The soil outlet A¹ is in the lower front part of the earthenware pan A and has
the valve B underneath it the space in the socket casting D above the valve and the
lower part of pan normally containing water from the flushing box C. The
water for the after flush is supplied through the passage D. The valve B is here
shown of a circular form and with a narrow rim which makes joint against the
rubber ring B. The pull handle E is connected to the lever F which passes along
the side and to the back of the pan and is pivoted at F1. The back of this lever and
the other mechanism for working the valves is at the back so as to be out of sight.
The valve B and the supply valve G are worked from the lever F the valve B by the
connecting rod H slotted tumbler I on a weigh-shaft I¹ and lever K also

The supply valve G is partly within the flushing box Cas shown. P is an earthen-
ware foot or foundation which encloses the lower part of the closet at the front and
at the sides but leaves the back and the working mechanism there free and open to
inspection. The wooden top Q is hinged so that it can be lifted up when the closet
is to be used as a urinal. K is a hinged seat lid.
Figure 5 is an elevation and Figure 6 a sectional elevation of a double valve ship's
closet of our improved construction which in all essentials is similar to the one
already described except as regards the additional valve S which is arranged below the
valve B and is of somewhat similar form and mode of action it is of circular form
with narrow rim which makes joint with a rubber ring S¹. The valve S is mounted
on a crank arm T₁ of the weighshaft T which on its other end is provided with
a slotted tumbler or lever U. This latter receives motion from the down continuation
of the rod H.
Figures 7 and 8 are modification of part of Figures 1 and 2, and shew a regulating
pipe or valve consisting of a downward bent pipe G¹ terminating in a horizontal
pipe G2 having a contracted end outlet and lateral outlet holes for governing the flow
of water into the basin under varying pressure.
Figure 9 shews another modification of part of Figures 1 and 2 and shows a
valve G2 of ordinary throttle valve form (or it may be other suitable form) for
regulating the flow of water into the pan under varying pressure.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is
-
1. The improved construction of ships water closet having an earthenware or other
suitable pan with lower front soil outlet and valve, front and side casing of earthen-
ware forming a foot or foundation and working mechanism arranged towards the back
substantially as set forth.
2. In ships valve closets the improved arrangement of supply valve regulator and
combined after flush and overflow substantially as set forth.
3. The improved construction of single and double ships water closet shown in the
drawings.
