5, is similar
in construction to a bread mixer. Instead of a pail, however, for the
dough ingredients, it has a deep pan _a_, and instead of one kneading
prong it has several prongs, which are attached to two arms _b_, as
shown. These arms are revolved by gear-wheels _c_ that fit in a large
gearwheel _d_ attached to a shaft _e_, which is turned by means of a
handle _f_. The large number of mixing prongs in a cake mixer are
necessary, because cake dough must be thoroughly stirred and beaten,
whereas in bread making the dough must be made to form a compact mass.

16. DISH-WASHING MACHINES.--Although machines for washing dishes are to
be had, they are most helpful where large numbers of people are served
and, consequently, where great quantities of dishes are to be washed.
Such machines are usually large and therefore take up more space than
the ordinary kitchen can afford. Likewise the care and cleaning of them
require more labor than the washing of dishes for a small family
entails. Large quantities of hot water are needed to operate mechanical
dish washers, and even where they are installed, the glassware, silver,
and cooking utensils must, as a rule, be washed by hand.
17. FIRELESS COOKER.--A device that has proved to be really labor-saving
is the fireless cooker, one type of which is shown in Fig.
