11 Claims. (Cl. 214-11)
The present invention relates to an improve
an inclined runway and come to rest on a re
ment vin receptacle inverting mechanisms, and
ceiving platform without spilling any milk what
more particularly to an improvement in can in
ever.
verting or “dumping” mechanisms especially
ȧ adapted for operation in timed relation with can
washing >machines of the type ldisclosed in my
Patent No. 2,023,431, dated December 10, 1935.
Automatic receptacle inverting mechanisms
are extensively used in the industries to perform
the act of »dumping or pouring out the liquid con
tents of the receptacles faster and more eflicient
ly than the act can be done by hand. The mech
anisms for inverting or dumping the large milk
cans used to transport raw milk from the pro
ducer to the receiving and distributing st-ations
are typical examples of such devices, and al.
though the mechanism ofthe present invention.
is applicable to the inverting of various kinds
of receptacles in order to automatically pour out
their contents, the invention will be described
with particular reference to the emptying or
dumping of the large cans used in transporting
fluid milk.
Thereupon an oscillatory cradle picks up»
the `filled can and swings it in a'vertical plane
to turn the can upside do-wn thereby emptying m
its contents at a higher plane into the milkV re
ceiving tank, at the same time depositing the
can in upside do-wn position on a> support from
which the can is removed and carried into the
washing machine before the next succeeding can
is dumped. By so arranging the can inverting
mechanism that the cradle begins its upward
swing on the upward stroke of the can trans
porting carriage of the washing machine the
cradle is started in its upward swing slowly and
gently without liability of accidentally spilling
the contents of the can.
And then as the car
riage reaches the limit of its upward movement
and starts forward the cradle carrying thev ñlled
can is accelerated in movement and the contentsr 20
thereof are swiftly and neatly dumped into the ’
receiving tank. without slopping over the sides of
the tank. The inverting mechanism is returned
It has been pro-posed heretofore- -to provide
to normal position largely under the -actio-n o-f
automatic can inverting or dumping mechanisms
for can washers, and there are many such in suc
gravity», but in order that there may be no delay
in bringing Athe cradle back to» normal position

resilient means put kunder tension from the can
many of them are objectionable in one or more
transporting carri-age is availed of to start the
cradle in its downward path.
Another object of the invention is to produce
acan invertingmechanism of such compact con
struction as to take upV relatively little ñoor
space, an important desideratum in connection
with many can washing machines now in opera
tion in restricted quarters which do not permitl
of the installation and operation of former kinds
of can inverting mechanisms requiring relative
ly `large floor space. In this connection the can
particulars, forrexamplarsuch as spilling or slop
ping out some _o-f the milk before the can reaches
the point at which it is dumped or because some
of the milk is spilt onto the outside of a preceding
can.
One object of the present invention is to pro
duce a can inverting or dumping mechanism of
such construction that no milk will spill or slop
over the top of the can before the can is posi
tively inverted or dumped into the milk receiving
tank.
A further object of the invention is to- produce

it returns tocan receiving position it does not 40

As described in‘my said patent, when the can

With this construction and timing of operation,
if the upper part of the can being deposited in up

40 forward, the upper end of the right side of the
can (viewing Fig. 4) would‘strike the finger |2|
and the can would be deflected by it against the
opposite guide rail |20, and thereby be prevented
from falling forward, it being understood that the
mouth of theV can is 'prevented from sliding for

The can would thereafter settle by gravity in up
