One of the applications where space 'mustl be
conserved is upon shipboard, as in sand suckers.
But since the proper functioning of the appara

Thus far it has been assumed that the appa
ratus has been maintained plumb. Suppose, how
ever, the vessel has a list, as to starboard or
port as indicated Figs. 4 and 5 respectively. Ob

Since the lip means past which overflow is had,
nular space therebetween is made Water-tight is above the elevation of the sealing member,
by a flexible sealing member 26, as of sheet rub- - there will be a hydrostatic pressure exerted up
ber, leather or the like. This member is annular
15 and has its edges -downwardly turned and se
cured to the adjacent parts as at 21, Fig. 3, with
an upward bight therebetween forming an an
nular upwardly extending pocket. llt will. be
noted that the bight of the sealing member is
20 disposed substantially below the plane of the
gimbal. The upper extremity of the tank body
I extends beyond the sealing member 26 to serve
as a backing therefor, and is perforated as at 28
to provide drainage from the space thereabove.
25
That the lip member may be responsive to level
of the tank liquid and the gimbal joint relieved
of the weight of the lip member, an annular float
29 of large diameter is provided and associated
in supporting relation with the lip member as
30 by a plurality of peripherally spaced brackets 30
arched as indicated to clear the gimbal ring 24
and its associated parts. The capacity of the
float is preferably approximately suiiicient to
support the lip means and its associated parts.
35. An annular trough 3| is arranged to receive
overiiow from the spillway 23 of the lip means,
anddrains 32 therefrom are provided as leading
to the overflow I3.
» Operation will be as follows, assuming feed be

wardly in the annular pocket thereof, the mem
ber acting as a piston. When the parts are ex
actly concentric the horizontal clearance indi
cated at C, Fig. 3, between the lip means and its
surrounding tank edge, which is closed by the
sealing member, will be perfectly annular so that
this pressure will be exerted equally entirely about 20
the periphery of the lip means.
Since, however, the center of motion provided
by the gimbal joint is above the sealing member,
the relative motion of the parts about this center
will increase this clearance at that part of the lip 25
means where the tank edge rises relative thereto
as at D, Fig. 5; and such relative motion will de
crease this clearance at that part of the lip means
where the tank edge lowers thereto as at E in
Fig. 4. But as this horizontal clearance becomes
greater the unit hydrostatic pressure will become
less, and vice versa, since the clearance can only
increase as the bight of the sealing connection 26
at that point approaches the liquid level just
above the lip means. It will be noted that the 35
elevation of the bight is a function of the differ
ence in elevations of the corresponding lip and
' tank parts, the bight moving up or down only one
half as far as the tank edge moves up or down

as indicated, and the valve I2 closed. Chambers
A and B of the `tanks will be ñlled with liquid
bearing solid particles. Overflow will be had by
way of the lip means and particularly the spill
45 way 23 thereof; intothe trough 3| thence over
board by way of the drains 32, overflows I3 and
scuppers I4.
Solid particles above a certain size and/or spe

tank 9, and smaller and/or lighter particles will

The parts are so proportioned and arranged
that these two functions of area and head offset
each other as they vary, so that in the last
analysis the lip means is responsive to the float,
as to level, and to the gimbal joint as to posi
tion. In any event it will be observed that the
lip means is maintained level independent of tilt
of the other tank parts of the apparatus, and
overilow will be maintained uniform entirely
50
about the periphery of the tank.

the valve being >balanced to closed position as is
usual in the art.

Suppose now the valve I6 be lowered and the
valve I2 opened, flow from the feed mouth 2I
will be ñrst downwardly into the chamber A
thence up over the lip of the tank 9, and down
wardly into the chamber B before overflow.
65 Some of the solid particles fed to the apparatus
will be so large and/or heavy that they will pass
downwardly into the delivery pipe II and never
attain the chamber B. As shown these products

be discarded but obviously the pipe I I might

any rate the tank I will deliver only those solids
