the other extremity to shift the trolleys to the a superstructure associated therewith, a series of '
5 left. 'Ihe cables i2 may be operated by a com
mon motor or by two motors properly con
trolled-suitable arrangement for this being
obvious and forming no part of the present in
vention. The slidable cross member is adapted
to engage with a carrier bar I on the conveyor
‘chain c and such engagement may be of a
mechanical nature or of a magnetic character.
The trolley mechanisms h, M, h", I13 and h‘ are
interconnected by members k5,.

In operation therefore it will be appreciated
that the articles are suspended from the carrier
bars I on the endless conveyors e and the inter
connected overhead trolley or conveyor mecha
nisms h, m, h'-', I13, and h‘ are such that the lower
‘ cross bars h2 engage carrier bars ,1’ and raise same,
following which the carrier bars are moved hori
zontally by cable 1’ and ?nally downwardly into
- the next adjacent tank by the motor 2'’ whence
the endless conveyor takes up itsduty and moves
25 the articles through the particular tank in ques
tion. In this manner the articles may be speedily
conveyed from one tank to the other and time
periods may be arranged whereby when the ar
ticles have been elevated away‘ from the liquid

trolleys.

combination with a plurality of aligned tanks
7 and a superstructure associated therewith, an
elongated carriage movably mounted on said 15
superstructure for linear travel above the tanks
and including a plurality of spaced elevator
guides, a plurality of elevators mounted in said
guides, common actuating means mounted on
said carriage to operate said elevators simultane
ously, and means for shifting said carriage and
its elevators as a unit linearly of the tanks.
3. In apparatus of the character described, in
combination with a sequence of tanks and a
framework carrying parallel conveyors adjacent
the sides of the sequence of tanks, a series of
transverse carrier bars normally supported at
their ends by said conveyors; a superstructure
forming part of said framework and arranged .

then slid on to the rubber sleeve 12 and is closed
in by suitable pressure to conform to the H-sec

secured to said superstructure substantially di
rectly above said conveyors; a plurality of trol
leys each comprising an elevator frame shiftable
longitudinally of the rails and having vertical,
guides, a laterally and horizontally disposed lift 35
ing bar operable vertically of said guides. and
mechanism for raising and lowering the lifting
