1 Claim. (01. 99-358)
The invention relates to a cooker designed for
cooking food articles such as frankfurters, ham
burgers and the like, the cooking being effected
by utilizing the article as a conductor for an

Yet another object is to provide a cooker of the

The invention possesses other objects and
features of advantage, some of which, with the
foregoing, will be set forth in the following de
scription of the preferred form of the invention
which is illustrated in the drawings accompany
and to the other lead 29 of such current.
In cooking the food articles, the frankfurter
or the like designated by the reference numeral
31, is positioned to extend across the arch [4, as
shown in Figure 2, and with its ends 32 and 33
extending into the wells is and I9; the wells being
?lled with a liquid such as a saline solution, which
will conduct an electrical current, and sufficient
liquid is placed in the wells to cover the terminals
and permit the immersion of the ends 32 and 33
in the liquid. In this manner when the terminals
are energized, the current will ?ow from the
liquid in one well through the frankfurter and
into liquid of the other well, thus heating the
tion may be adopted within the scope of the in
frankfurter so that by leaving the current on for
