A can crusher for flattening cans is provided which has a cylindrical
body having a first upstream end and a second downstream end. A
fluid cylinder having a piston rod is connected to the first end
of the body and a piston rod is mounted within the body and attached
to the piston rod for movement from a retracted upstream position
to an extended downstream position. A discharge opening is provided
in the body adjacent the downstream end thereof. A can receiving
opening is provided in the body spaced a distance from the discharge
opening at least equal to the maximum can height to be accommodated
by the can crusher. A ripper tooth extends longitudinally within
the body from the can receiving opening to the discharge opening.
A control device selectively supplies hydraulic fluid to opposite
ends of the fluid cylinder to move the piston between the retracted
position and the extended position to simultaneously drain liquid
from the can as it is crushed. The piston has a longitudinal groove
aligned with the ripper tooth through which the ripper tooth passes
when the piston moves between the retracted position and the extended
position.
A beverage can crusher has a pair of rollers which rotate toward
one another to crush a can between them. The crusher has a deposit
window and chute which place the cans above the rollers and ensure
that the cans are flattened from the sides rather than smashed from
the top. This provides for a repeatable, baleable crushed can. An
actuator placed less than one can length above the rollers in the
chute energizes the drive motor to rotate the rollers and continues
to have the rollers rotating as long as there is a can engaging
the actuator The rollers have a special receiving surface and engaging
surfaces which grip the sides of the can to minimize slipping so
that the can will be pulled down between the rollers. In addition,
pins extend radially outward from the outer surface of the rollers
to further grip the can.
A lamp crusher housing is mounted on the removable cover of a replaceable
waste container to discharge crushed lamps into the waste container
through an opening in the cover. An elongate, plastic sleeve is
removably and sealingly secured at one end over the upper end of
the waste container, and at its opposite end around the outlet of
the housing from which crushed lamp particles are discharged. The
sleeve has an excess portion folded into the waste container so
that when the cover is lifted from the container opposite ends of
the sleeve bag remained sealingly connected to the waste container
and housing outlet so that no toxic gases are allowed accidentally
to escape into their surrounding atmosphere. The apparatus includes
a replaceable filter cartridge for filtering out mercury vapors,
and the like. Each cartridge contains a fuse which is connected
in the circuit that controls the motor that drives the lamp crusher.
When a new cartridge is placed in the apparatus its fuse is connected
into the control circuit and permits only a predetermined number
of lamp crushing operations to occur, after which the motor will
be prevented from further operation until the saturated cartridge
is replaced by a new, clean cartridge.
A rolling bearing arrangement for a conical crusher in which a
vertically arranged driving element is rotatably mounted on a base
and a crushing cone is mounted inclined with respect to the vertical
on the upper end of the driving element so as to be freely rotatable,
characterized in that the rolling bearing arrangement comprises
a single common hollow cylindrical outer part in which two inner
rings situated axially behind each other are supported on rolling
elements, the outer part being part of the driving element and the
first inner ring being connected with the base whereas the second
inner ring, which is arranged inclined and eccentrically offset
with regard to the first inner ring, carries the crushing cone.
