‘1 Claim. (o1.124s_20)
This ‘invention relates to washing machines used
'for laundering clothes, and. more particularly. to
machines of this class (which are automatic‘ in
their operation, having for its'object to .provide
a construction which is sturdy andwelladapted
to withstand and/or absorb the considerable
amount of .vibrationand strains which are inher
ent insuch machines during their operation.

tion resides in the noveldetails .of construction
and combinations .of parts as will iber-disclosed
