PROVISIONAL SPECIFICATION.
Improvements in and connected with Apparatus for Flushing Closets,
Tanks, and the like.
We, THOMAS GARFORTH RHODES, RAYMOND GAUNT, and JAMES BARKER
LRDGARD, of The Valveless Syphon Company, Kirkstall, near Leeds, Engineers do
hereby declare the nature of this invention, to be as follows:-
According to our improvements we employ a special construction of chill mould
for moulding the syphon charging chambors of the vertical, horizontal, or inclined
pattern, and valves used in connection with the said charging chambors.
The cistern may have two compartments, one forming the flushing chamber, the
other the supply chamber, the flushing chamber may be fitted with any style of
automatic flashing arrangement, the supply chamber is fitted with a "Grants"
other form of waste preventing valve, and the necessary supply ball valve.
The object being to flush the closet some time after the user has left the seat.
The closet being flushed by connecting the seat action with the valve lover, or by a
pull chain. The syphon pipe is made with a double bend, the object of this being to
give a momentary check to the water.
The closet basin has two traps, the vacuum between the two is maintained during
the air charge of the closet by means of a valve. The vacuum is then broken at the
end of discharge by an air hole in the basin communicating with the vacuum chamber,
or subsidence below trap fluid. A special form of joint is also provided.
Also an improved form of after flush cistern in which a tipping vessel containing
the after flush charge is placed in the flushing cistern and after the main discharge
the contents of the tipping vessel are emptied into the closet basin to fill up the trap
of same, by means of auxiliary syphon.
Also an automatic flush cistern or tank having a syphon provided with an air
chamber and drop spout, also with a small syphon pipe for insuring the trap or seal
being filled after each operation.

Tanks, and the like.

page_text: DESCRIPTION OF DRAWINUS.
Fig. 1, is a front elevation of our improved automatio flushing apparatus.
Fig. 2 is a side elevation of Fig. 1.
Fig. 3, shows in sectional elevation our improved closet basin with two traps.
Fig. 34, shows cross section of alternative ball valve for use with closet basin in
Fig. 3.
Fig. 4, shows in sectional elevation a modification of Fig. 3.
Fig. 5, shows a circular leaden trap which may be used in place of bulb trap shown
in Fig. 4.
Fig. 6, shows in section, our special joint for earthenware and lead pipes.
In Figs. 1 and 2, A is the flushing chamber, containing some form of automatic
syphon D, and B is the supply chamber which contains the necessary supply ball
valve. The two chambers are connected by a Grant's or other form of automatic
valve C. A lever G which is pivotted at J to the bracket K, and which is worked by
the seat action, is connected to this valve C by means of the connecting rod F,
weighted at H, and the lever E. Thus on the user leaving the seat, the weight H
causes the valve C to open, admitting the water to, and gradually filling the chamber A.
This allows a short time to elapse between the use of the closet and the flush, which
occurs when the pressure of water in A is sufficient to start the syphon D. When
the supply chamber B is emptied, the valve C closes automatically and the bali valve
fills the chamber again ready for the next operation.
In Fig. 3, the closet basin L has two traps M and N, with a vacuum chamber O
between them. A small air passage with ball valve Q communicates with the supply
pipe P, and by means of this valve the pressure of air in O is maintained until the
Hush occurs, when the ball is raised and the air is gradually exhausted from O by the
water passing the opening under the ball. Then when the basin L is almost filled,
the pressure in O is overcome, and the water rushes through the traps. A small cap R
is fitted to tho hole where the ball Q is inserted.
In Fig. 8, the valve Q is shown in a small side chamber A', which is connected to
the supply pipe P by means of the small hole B' and to the vacuum chamber O.
The ball Q is lifted by the suction of the water passing through the supply pipe P.
In Fig. 4, which is a modification of Fig. 3, we have the basin S with the trap T.
In place of the second trap N of Fig. 3 we employ the loaden bulb trap U, thus
effecting a considerable saving of space. A small pipe Y, which takes the place of
the ball valve Q of Fig. 3, allows the air in the chamber W to escape to the supply
pipe X as the pressure in the basin S increases. Thus the trap is flushed by the
whole volume of water together instead of in a smaller continuous stream. Or we
may employ, in place of the bulb trup U, the circular leaden trap V (Fig. 5) which is
also provided with a small air pipe Y
In Fig. 6, our joint is shown, in which the earthenware pipe has a flange A' with
tapered socket B, into which we place the tapered end D of a brass ferrule C, the
space between D and A' being then filled with cement E'.
The lead pipe is then soldered on to the brass ferrule C'.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed wo declare that what we
claim is :-
1. The automatic flushing apparatus consisting of the cistern with charging
chamber A, supply chamber B, valve C, syphon D, levers E, and G, connecting
rod F, and spring or weight H, substantially as shown and described.
2. The closet basin L, with traps N, and M, vacuum chamber O, supply pipe P,
and ball valve Q, substantially as shown and described.
3. The closet basin S, with trap T, bulb trap U, or circular trap V, vacuum
chamber W, supply pipe X, and small air pipe Y, substantially as shown and described.

page_text: 4. Forming the joints for earthenware and lead tubes with flange A', having.
tapered socket B', brass ferrule C', having tapered end D' and cement E,
substantially as shown and described.
