This article discloses a mechanism for the filling of receptacles to a specific
weight level that will prevent overfilling.
The figure discloses a chamber 10 containing a receptacle 11 into which
material is to be deposited. To prevent overfilling of the receptacle, the
receptacle itself is placed upon a spring-loaded platform 12 contained in the
chamber. One end 13 of the platform is free and is biased upward by spring 14,
while the other end 15 is connected by a hinge 16 to the floor of the chamber 10.
The spring holds the platform and receptacle such that when the receptacle is
filled to the desired level the platform will be forced down against the bottom of
the enclosure. The platform moving down causes a door 17 to close off the
chute 18 through which the receptacle is filled, to prevent additional material
being placed into the receptacle. This closing of the door 17 is accomplished
through a bar 19 attached to the free end 13 of the platform, which moves an L-
shaped pivoting member 20. As the member 20 pivots, a triggering lever 21 is
pulled back, reclosing the door 17 which falls across the loading chute 18 and
thus prevents additional material from being deposited in the receptacle. If
desired, the door can have a legend on it indicating that the receptacle is filled to
the desired level.
