Improvements in Apparatus for Emptying Baths.
I, LOUIS FRANÇOIS POURNAY, Locksmith of 33 Avenue Rapp, Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to provide an apparatus by means of which the
outlet valve of the bath may be opened from the outside without withdrawing the
plug from the interior by hand as is usual; and consists in connecting the outlet
valve to a lever underneath the bottom of the bath, the said lever being itself
connected to a handle attached to the side of the bath. This handle is normally
held up by a spring to close the outlet valve, but on being depressed by hand opens.
the said valve and is retained in such depressed position by means of a spring or
other suitable catch, until again released by hand when the aforesaid spring
automatically returns the operative parts to their normal positions and closes the
outlet valve.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Emptying Baths.
I, LOUIS FRANÇOIS POURNAY, Locksmith, of 33 Avenue Rapp, Paris, in the
Republic of France, 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 has for its object to provide an apparatus by means of which the
outlet valve of the bath may be opened from the outside without withdrawing the
plug from the interior by hand as is usual; and consists in connecting the outlet
valve to a lever underneath the bottom of the bath, the said lever being itself
connected to a handle attached to the side of the bath. This handle is normally
held up by a spring to close the outlet valve, but on being depressed by hand opens
the said valve and is retained in such depressed position by means of a spring or
other suitable catch, until again released by hand when the aforesaid spring
automatically returns the operative parts to their normal positions and closes the
outlet valve.
This apparatus, represented in section by Fig. 1 of the annexed drawing is
constructed as follows:-
A tube a is closed at its two ends by stops c and d fixed to the tube. In the
centre of these stops a hole is made for the rod f which carries at its lower end 'a
fork joint g to which is attached the connecting rod h. The upper part of the rod f
carries a knob 7. Inside the tube is placed a spiral spring m resting on the bottom d
and the other end of the spring bears underneath a washer e fixed to the rod fin
such manner that the latter may be always raised in the tube. Another washer e'
fixed solidly to the rod limits the upward movement thereof.
This apparatus is fixed at the edge of the bath (as shown in Fig. 2) in the centre
of its length, and in a hole made for the purpose. Underneath the bath a lever i,
oscillating on a pivot n placed at its centre, is attached at one end to the con-
necting rod h whilst the other end supports the valve plug o.
The rod being

rod h. The weight of the water in the bath insures the complete closing of the
valve.
In order to empty the bath, it is sufficient to press on the knob of the apparatus
until the spring catch P engages underneath the knob e. In this position the rod f
is held down and in its movement it has oscillated the lever i and raised the valve o.
In order to close the valve and fill the bath afresh the spring catch P must be
released by bearing on the hook P' when the spiral spring at once comes into action
and raises the rod, bringing the valve down on its seat.
Fig. 3 represents the same apparatus carrying two holding pieces 6 for fixing on
the bath or to the wall; this arrangement is sometimes rendered necessary by it
being impossible to carry the apparatus through the edge of the bath.
Each holding piece, as also the body of the pivot n, forms part with plates
provided with screw or rivet holes for their attachment.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
An apparatus for emptying baths comprising a valve arranged at the bottom of
the bath, and which is raised when it is desired to empty the bath, by a pivoted
horizontal lever actuated by a vertical connecting rod jointed to a piston rod
constantly forced upwards by a spiral spring but able to be held in the lower
position by means of a spring catch which prevents the expansion of the before-
mentioned spring, this catch resting against the interior side of the cylindrical body.
of the apparatus.
