The present invention relates to material sepa
rating apparatus of the vibratory type, such as,
for example, riddles, strainers and the like and
has for its principal object, the provision of sepa
rating apparatus of the type mentioned having
improved means for mounting the strainer or
sifter container, or like separating element, upon
the main frame of the apparatus.

provided with a pair of oppositely disposed, trans
versely projecting footlike extensions 6 which
serve to hold, or support, a conventional strainer
or sifter container, or other similar separating
element 8, which, in the embodiment shown, is
provided with a top closure 9.
As customary, the frame 2 is equipped with
spring means I!) so that it might be resiliently
suspended in operable position from a rigid sup
