which is adapted to agitate the corn during a popping
operation without any eed for manual manipulation.
A further important object of the present invention is
to provide a novel popcorn popper which is constructed
for presenting unpopped kernels relatively directly to the
heat source to promote rapid heating and popping thereof
which structure is also adapted to direct popped corn
away from the heat source so as to minimize any pos
sibility of burning thereof.
Still another object of the present invention is to pro
vide a novel popcorn popping structure which is con
structed so that unpopped kernels are relatively directly
exposed to a heat source while popped kernels are rela 45
tively shielded and insulated from the heat source where
by rapid popping of the kernels is prompted and any
possibility of burning of the popped corn is minimized.
S 'll anot' er object of the present invention is to pro
vide a novel popcorn popping structure of the above de
scribed type which may ‘oe selectively adapted for pop
ping the corn either with or without the use of oil and
the like.
A more specific object of the present invention is to
provide a popcorn popper of the above described type
which is of simple and rugged construction.
A further specilic object of the present invention is to
provide a novel popcorn popper structure of the above
way of example only it may be stated that 1G mesh, 30
gauge wire cloth has been found to be particularly suit
Preferably the wire cloth is nickel plated or the
like, so as to facilitate washing and cleaning and to mini
mize any possibility of rustinv.
In accordance with an important feature of the present
invention it is to be noted that the basket member 24
is formed so that it has a relatively small lower end por
tion for coniining kernels 3@ of unpopped corn, as indi
cated in FIG. 2, and side walls which diverge upwardly
from the lower end portion for providing an enlarged
chamber for receiving popped corn 32, also as indicated
in FiG. 2. Preferably the basket member is provided
with a substantially inverted frusto-conical configuration
for facilitating uniform heating and processing of the
corn in the manner described more in detail below.
configuration also simplifies production of the basket
lmember and provides a rounded or cornerless construc
tion which facilitates cleaning. Preferably an upper mari
gin of the basket member is welded or otherwise fixed
to a relatively heavy gauge annular re-enforcing wire 34.
As indicated above, the construction of the basket
member 2d is such as to promote rapid heating of un
popped kernels Sti at the lower end of the basket member
while reducing any possibility of overheating and burn
ing of the popped corn 32. More specifically, it will be
noted that, as shown best in FIG. 5, the wire cloth is
formed from crossed wires 3d and 38 which define aper

merges with another portion which not only extends
laterally but is also curved or arched.
While the mem
ber 4Z is preferably formed from a relatively heavy
gauge resilient wire, it may be formed from any suitable
resilient or spring material.
A feature of the present invention which it is important
to note, is that the arm member 42 described in detail
above, provides a resiliently yieldable or spring support
for the basket member 24. With this support it has been
found that the force of the explosions from the popping
corn will cause the basket member to bounce, which
