Bronze or brass rather than steel or iron should be used for any
bearings that come in contact with water. Only thus can you fully
safeguard against rust.




LITTLE THINGS THAT OFTEN PROVE GREAT.


Safety demands that every equipment involving an electric motor be so
fully insulated from the machine frame by water-proof fittings and
insulated shaft couplings, etc., that a maximum of safety can be
assured. It is indeed remarkable that this is not more often cared for
in the original design. In one short period, at least three machines
were forced into the disapproval group in the Department of Household
Engineering of Good Housekeeping Institute with such lack of insulation
as one of the causes.

It is thus clear that consumer needs, in this great classification of
merchandise (household appliances) as reflected by consumer attitude
are often ill-defined and extremely difficult for the manufacturer to
interpret. Therefore, as a recognition of this condition, the basic
purpose running throughout all of the testing work at Good Housekeeping
Institute is to test every device so as to duplicate the conditions
under which the device will be used by the ultimate consumer, be she
intelligent or unintelligent. It has furthermore been the Institute's
special province to express to each manufacturer the trend of consumer
demand as seen, not only through the Institute's use of appliances, but
through the thousands of consumers who report their experiences.
