supply of liquid to a receptacle and its discharge therefrom,
a bucket or buckets for operating such valves, pipes or
passages for conveying liquid to fill such bucket or buckets
and the space surrounding the same respectively, a siphon
for emptying such bucket and a siphon or valves for empty-
ing the space surrounding such bucket, substantially as
specified. (30.) The combination with a receptacle whose
contents it is desired to discharge at two or more
levels, of two or more valves for discharging such con-
tents at the desired levels, which valves are successively
opened by the action of the discharging apparatus, sub-
stantially as specified. (31.) The combination with a lever
for controlling the supply and discharge of a receptacle, of a
second lever connected to the former, and also to valves so
as to effect the discharge at different levels, substantially as
specified. (32.) The combination with a receptacle whose
contents it is desired to discharge at two or more levels, of
two or more valves suspended from a lever or levers, and so
adjusted as to weight that in the absence of pressure on them
the lower valve will remain open while the upper valve or
valves remain closed, but that with a certain pressure of
water upon the lower valve an upper valve will open while
the lower valve remains closed, substantially as specified.
(33.) The combination with a lever for controlling the supply
and discharge of a receptacle, of a second lever connected to
the former, and also to valves so as to effect the discharge at
different levels, the weights of the discharge-valves being so
proportioned that when the discharge first begins the
higher valve will be opened, and remain open until the level
of the liquid falls to such an extent that the weight of the
higher valve overcomes that of the lower one, and thus
closes the former and opens the latter, substantially as
specified. (34.) The combination with the discharge-wells
of a pair of filters or other receptacles and a pair of actuating
buckets suspended therein, of a siphon serving to convey a
portion of liquid from either of the discharge-wells to the
opposite actuating bucket, and by its continued action to
