Year: 1886

page_text: I, ALFRED JULIUS BOULT, of 323 High Holborn, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention (a communication from
Bernard Havanagh, of the city, county, and State of New York, United States of
America, Plumber,) 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 that class of water closets known as "wash out closets,"
and the novelty consists in the construction arrangement and adaptation of parts
as will be more fully hereinafter set forth, and specifically pointed out in
the claims,
A great fault with this class of closet has been that the basin did not contain
a sufficient quantity of water to prevent the basin from becoming foul, and the
water feed has not been properly proportioned to insure a thorough cleansing of
the basin.
The inventor has discovered that a depth in the basin of less than two and a
half inches will not serve the desired purpose, and has worked out practically
a construction whereby he provides that or a greater depth and at the same time
have so proportioned the feed inlets that the basin will be entirely cleansed at each
operation of the valve.
I provide a basin having a water holding concave of an area slightly larger than
that of the seat hole and with the escape passage arranged beneath the cover and
out of sight. I provide that water may be admitted to wash out the concave by
force, and to flush the sides of the basin. So far however, the invention is not
new with me, as such a construction is shown in English patent No. 2969 of 1883.
I provide an auxiliary chamber adjacent to the side of the basin opposite the
discharge, the capacity of which approximately corresponds with that of the basin
concave in order that, after the valve is closed, there will be sufficient water in
the auxiliary chamber to fill the concave without "head."
I provide that the feed water shall pass in an inclined plane directly to a long
narrow inlet passage, arranged slightly above the water level in the concave-in

page_text: order that the first force of admitted water will be directly upon the water in the
concave, ordinarily the soiled water, and that the remaining force of water, after
the auxiliary chamber is full, will serve to flush and cleanse the inner surface of
the basin.
To accomplish this successfully requires peculiar and arbitrary proportions to be
given to the water passages.
With this general statement of the improvement I refer to the accompanying
drawings which form a part of this specification, and in which:
Fig. 1 is a top plan of my improved closet..
Fig. 2 is a longitudinal vertical section.
Fig. 3 a transverse section, and
Fig. 4 is a longitudinal vertical section of a modification.
In the drawings-A designates the basin, having a water holding concave
bottom a; of an area slightly larger than that of the seat hole a¹ and arranged
fairly beneath said hole. B designates the discharge passage arranged outside of
the hole area so as not to be visible in the ordinary use of the closet. The concave
is slightly oval, and is so formed that a force of water from the inlet c will tend
to throw the contents over the bridge b which lies between the concave and the
discharge B..
:
The seat is arranged transverse to the direction of the water flow-with the
water inlet upon one side and the discharge B upon the other. This economizes
space and makes the arrangement compact and convenient.
Above the discharge pipe B the part of the basin marked A¹ is expanded to
form side chambers fand shoulders 1 adjacent to the line of the bridge b. These
parts perform important functions. The water is expelled from the concave by
force, and when it strikes the face of the basin it is liable to spatter back, and this
back flow is liable to impede the proper cleaning. By my construction the water
as it strikes the inner face of the basin above the discharge becomes separated and
dashes to each side-within the recesses f. The shoulders f¹ prevent such dashing
water from again reaching the concave. To provide these recesses and shoulders
the basin is contracted upon the line of the bridge b, as indicated at F.
Upon the side of the basin A opposite the discharge B is a distributing chamber C,
having a capacity corresponding with that of the concave a, and having its wall
adjacent to the basin provided with a long narrow water passage c, slightly above
the standing water level and a water passage e in the upper part which connects
with the flushing rim E.
The water inlet pipe D, I preferably arrange at an angle nearly corresponding to
that of the adjacent side of the concave. I show it as extending through the
chainber C and connecting with the water passage o having within the chamber C
openings o' which connect the interior of the pipe with the interior of the chamber.
The proportions of these water passages are important. That of the pipe D
being say of a diameter of one and a quarter inches, the passage c should be one
inch long by one fourth of an inch wide in order to carry a "head" sufficient to
insure the displacement of the soiled water in the concave while that of the
passage & should be a scant half inch diameter, the combined area of the two
passages cand e being less than that of the feed pipe D. The size of the passage
or passages o¹ may be adjusted within wide limits.
In the operation of my closet, the ordinary valve, not shown, having been opened,
the water under force will pass through the pipe D, directly to the passage o, where
it becomes spread, and operates upon the contents of the concave. with a force
sufficient to force such contents, the soiled water and solid matter over the
bridge b. Meanwhile the water has passed through the passage c', has filled the
chamber C, and has passed into the flushing rim E. But by the time this cleansing
operation is well under way the solid and foul matter has passed over the bridge
to the discharge. After the valve is closed the chamber C will hold sufficient
water to just fill the concave.

page_text: Instead of passing the pipe D through the chamber C, I may arrange the bottom
of the chamber C at the desired incline-the object in either case being that the
first of the water will act as a ram upon the contents of the concave.
I deem the chamber C important in this construction.
By this arrangement of water feeding and water controlling devices I may
employ a concave from two and a half to three inches deep or deeper at the
portions where the solid matter is deposited. This depth of water insures that the
bowl shall be kept clean and by my device this amount of water will be expelled
at each working of the valve.
Modifications in details of construction may be made-without departing from
the principal or sacrificing the advantages of my invention, the essential features
of which have been set forth.
Having now particularly described and ascertained the nature of my said
invention, as communicated to me by my foreign correspondent, and in what
manner the same is to be performed, I declare that what I claim is :-
1-In a water closet, substantially as described, the combination with the bowl A
having concave a located beneath the seat hole and having bridge b separating said
concave from the discharge, of the distributing chamber C having a capacity
corresponding with that of the concave, and located but slightly above the concave,
and water connections as Dce, whereby water sufficient to fill the concave is
always held in position to drip therein after the valve has been closed, as set forth.
2 In a water closet as described, the combination with the basin A having
concave a with bridge 6 and with the distributing chamber C having water
passages e and c, of the pipe D connecting with the passage c and having passages c¹
opening within the chainber C, as set forth.
3-The basin A having concave a and discharge B separated by a bridge, com-
bined with water inlet D c, and with shoulders or abutments for preventing back
dash, as set forth.
4-The concave a, bridge b and discharge B extending across the seat, combined
with the water inlet upon the side of the seat opposite the discharge, the basin
being contracted at F to provide shoulders f' at points on a line with the bridge, as
set forth.
5 The closet described, consisting of the basin A. A¹ contracted at F to form
shoulders and recesses f, and having concave a and bridge b, the water inlet
upon one side of said basin, and the discharge upon the opposite side, the whole
arranged to throw the expelling water crosswise to the plane of the seat, as
set forth.
