Johnson - Egg Beater African American, Willis Johnson
of Cincinnati, Ohio, patented an improved mechanical egg beater (U.S. pat#
292,821) on February 5, 1884. In fact, what Willis Johnson had really invented
was an early mixing machine and not just an egg beater. Willis Johnson's
device was not intended for eggs alone. Willis Johnson had designed his
egg beater and mixer for eggs, batter, and other baker's ingredients. It
was a double acting machine with two chambers. Batter could be beaten in
one section and eggs could be beaten in another section, or one section
could be cleaned while the other section could continue beating.
Abstract: The object of [the] invention is to provide a machine
wherewith eggs, batter, and other similar ingredients used by bakers, confectioners,
&c., can be beaten or mixed in the most intimate and expeditious manner.
The machine consists, essentially, of a main frame within which is journaled
a driving-wheel and a pinion or pulley, the horizontal shaft of the latter
having at its opposite ends clutches or sockets, with which are engages
square or other non-circular arbors at the inner extremities of a pair
of beater shafts. Theses shafts, which are armed with suitable blades,
beaters, or stirrers, are journaled in cylinders that occupy detachable
trays or racks applied to the opposite sides of the main frame, hooks and
staples or the convenient devices being employed for retaining said racks
in their proper places. As a result of this construction, either one or
the other of both cylinders can be readily applied to the racks, and the
latter can be coupled to the machine, so as to insure a very rapid revolution
is applied to the driving-wheel, as hereinafter more fully described.
