PROVISIONAL SPECIFICATION.
Improvements in or connected with Lavatories, Baths, Sinks, and
the like.
I, JOHN SILANKS, of Tubal Works, Barrhead, in the County of Renfrow, North
Britain, Sanitary Engineer, do hereby declare the nature of this Invention to be
as follows, that is to say:
My said Invention relates to the discharge and overflow appliances of lavatories,
baths, sinks, and the like, and has for its object to improve the construction and
arrangement thereof and connected therewith.
In one improved arrangement the discharge valve, preferably made somewhat
heavy, closes down on a seat below a fixed or movable grating of metal or earthen-
ware in the outlet of the lavatory basin or other vessel. The valvo is attached
to an arm on a vertical rod which is outside of the vessel, and which in one
modification extends up through the overflow passage preferably made as described
in my patent Specification No. 5557 of 1896, and through a stuffing box at the
top thereof to a handle. In another modification a rod fixed to the valve extends
directly downwards and may pass through a trap in the discharge pipe, proceed-
ing through a passage which may be a stuffing box, its bottom end being acted
on by a lever connected to a rod having a handle at its upper end. Or the valve
rod may have its bottom projecting end enclosed within a sheath or cover of
rubber or the like fixed to the part through a passage in which the rod passes.
In another arrangement the discharge outlet from the vessel is preferably in a
depressed or well-like part, the discharge pipe extending up into the well and
having an annular space round it. The valve is in the form of a bell dipping into
the annular space, and has fixed to it a rod extending downwards and connected
to a handle in any of the ways hereinbefore described. The discharge pipe is
made with a deep siphon bend corresponding to the maximum depth of water
which the vessel is intended to hold. When water fills the vessel air becomes
compressed between the valve bell and the deep siphon bend and maintains the
water in the basin; but on the valve bell being raised to a small extent siphonal
action takes place and the water in the vessel discharges. To insure very coin-
plete drainage an inner annular siphon passage is formed by a piece covering the
upwardly projecting end of the discharge pipe.
Instead of starting the siphonal discharge action by lifting the valve bell, it
may be done by opening a valve in a small siphon pipe the short leg of which
dips into the water in the deep siphon bend, and the long leg of which extends
down into the waste pipe or final descending part of that bend. Or the valve
may be in a communication between the lower part of the deep siphon bend and
the waste pipe. Or the action may be started by a small jet of water directed up
the ascending leg of the siphon from a rubber ball which refills itself from the
siphon bend, the jet being produced by compressing the ball by menus connected
to a handle.

I, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary Engineer, do hereby declare the nature of this invention and
in what mauner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say :-
:-
My said Invention relates to the discharge and overflow appliances of lavatories,
baths, sinks, and the like, and has for its object to improve the construction and
arrangement thereof and connected therewith.
Eight modifications of apparatus as made according to my Invention, are shown
in vertical section on an accompanying sheet of explanatory drawings. In these
drawings the same reference letters are used to mark the same or like parts
wherever they are repeated.
In one improved arrangement, shown in figure 1, the discharge valve, A,
preferably made somewhat heavy, closes down on a seat below a fixed or movable
grating, B, of metal or earthenware in the outlet of the lavatory basin, C, or other
vessel. The valve, A, is attached to an arm, E, on a vertical rod, G, which is
outside of the vessel, and which extends up through the overflow passage, H,
preferably made as described in my patent Specification No. 5557 of 1896, and
through a stuffing box at the top thereof (if such be desired) to a handle, J.
In another modification shown in figure, 2, a rod, K, fixed to the valve, A,
extends directly downwards, and passes through a trap, L, in the discharge pipe, M,
and through a guiding part, N, and has its bottom projecting end enclosed within
a sheath or cover, P, of rubber or other suitable material fixed to the guiding
part. The bottom end of the valve rod, K, is acted on by a lever, E, centered on
a small bracket, Q, in a piece with the discharge pipe, M, the lever being con-
nected to a vertical rod, G, having a handle, J, at its upper end. The part, N,
may however be formed like a stuffing box, and the projecting end of the valvo
rod, K, may be acted on directly by the lever, E.
In another arrangement shown in figure, 3, the discharge outlet from the vessel
is preferably in a depressed or well-like part, R, the discharge pipe, M, extending
up into the well, and having an annular space round it. The valve, A, is in the
form of a bell dipping into the annular space, and has fixed to it a rod, K,
extending downwards and having its lower end enclosed in a sheath or cover, P,
and acted on by a lever, E, connected to a rod, G, and handle. The discharge
pipe, M, is made with a deep siphon bend corresponding to the maximum depth of
water which the vessel is intended to hold. When water fills the vessel air
becomes compressed between the valve bell, A, and the deep siphon bend and
maintains the water in the basin; but on the valve bell being raised to a small
extent siphonal action takes place, and the water in the vessel discharges. To
insure very complete drainage an inner anuular siphon passage is formed by a
piece, S, covering the upwardly-projecting end of the discharge pipe, M. The
valve bell, A, and the siphonul piece, S, are made with feet, D, to stand on the
bottom of the well-like part, R.
In the modification shown in figure, 4, the valve bell, A, is connected to the
handle, J, similarly to the valve of the modification first described.
Instead of starting the siphonal discharge action by lifting the valve bell, A, it
may be done by opening a valve, T, in a small siphon pipe, U, shown in figure, 5,
the short leg of which dips into the water in the deep siphon bend, and the long

page_text: leg of which extends down into the waste pipe, or final descending part of that
bend. When a discharge takes place the siphon, U, becomes filled in consequence
of the upward rush of the water acting on its short leg and of the suction acting
on its long leg. The siphon, U, is of small bore and the water hangs in it until
air is admitted by the valve, T, and then the dropping of the water in the
siphon, U, starts the main siphonal discharge. Or as shown in figure, 6, there
may for the same purpose be communication between the lower part of the deep
siphon bend and the waste pipe by means of a small pipe, V, controlled by a
valve, W, which is connected by a lever, X, and a vertical rod, G, to a handle.
Or the well-like part, R, may communicate (as shown in figure, 7) with the
discharge pipe, M, by a small pipe, V, controlled by a valve, W, connected by a
lever, X, and a vertical rol, G, to the basin handle. Or again the siphonal
discharge action may be started by a small jet of water directed by a pipe, Y, up
the ascending leg of the siphon from a rubber ball, %, which refills itself from the
siphon bend, the jet being produced by compressing the ball by means of a
small piece, F, connected by a vertical rod, G, to the basin handle.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. Improvements in or connected with lavatories, baths, sinks, and the like,
comprising a dischargo valve arranged to close down on a seat below a fixed or
movable grating of metal or carthenware in the outlet of the vessel, the valve
being attached to an arm on a vertical rod extending up through the overflow
passage and terminating in a handle substantially as hereinbefore described with
reference to figure, 1, of the accompanying drawings.
2. Improvements in or connected with lavatories, baths, sinks, and the like,
comprising a discharge valve arranged to close down on a seat below a fixed or
movable grating of metal or earthenware in the outlet of the vessel, the valve
being attached to a rod extending downwards through a trap in the discharge
pipe, and passing through a guiding part, which may be a stuffing box, and having
its end either enclosed or not within a sheath or cover of rubber or the like, and
acted on by a lever connected to a rod terminated by a handle substantially as
herein before described with reference to figure, 2, of the accompanying drawings.
3. Improvements in or connected with lavatories, baths, sinks, and the like,
comprising the formation of the discharge outlet from the vessel in a depressed
or well-like part, and the extension of the discharge pipe up into this well-like
part, and covering it there with a small siphonal piece, between which and the
sides of the well-like part there is a small annular space into which tho valve
(made in the form of a bell) dips, the valve being lifted to start the siphonal
action by means substantially such as herein before described with reference to
figures, 3, and 4, of the accompanying drawings.
4. Improvements in or connected with lavatories, baths, sinks, and the like,
comprising the formation of the discharge outlet from the vessel in a depressed
or well-like part, and the extension of the discharge pipe into this well-like part,
and covering it there with a small siphonal piece, between which and the sides
of the well-like part, there is a small annular space in which the valve (made in
the form of a bell) dips, siphonal action being started by any of the devices described
with reference to figures, 5, 6, 7, and 8, of the accompanying drawings.
Dotad this first day of November 1897.
