"CERTAIN IMPROVEMENTS IN FRYING PANS." A communication.
by James Edgar and Alfred Bardell, the first of the City of New York, and the
second of Brooklyn, both of the County and State of New York, United States of
America.
This Invention consists in a frying pan, the bowl and handle of which are both
stamped out of a single piece of sheet metal, the handle being strengthened at its.
junction with the bowl by vertical flanges, so that a frying pan is obtained which
is light, durable, easily cleaned, and not liable to leak. With the pan handle is
combined a ventilated covering plate, so that the handle can be taken hold of with-
out danger of injuring one's fingers either by its edges or by heat, the covering
plate being arranged to catch over or around the flanges of the handle and being
provided with a hole which registers with a suspension hole in the handle, and also
forms a source of communication between the opening at the outer end of the covering
plate and the atmosphere.
This Invention is illustrated in the accompanying Drawing. Fig. 1 represents a
plan or top view of a pan embracing the Invention; Fig. 2 is a longitudinal central
section thereof; Fig. 3 is a cross section of the pan handle in the line x, x, Fig. 2;
Fig. 4 is a like section in the line 3, y, Fig. 2; and Fig. 5 is a plan showing the
blanks for the pans.
Similar letters indicate corresponding parts.
In these Drawings the letter A designates the bowl or body of the frying pan, which
together with the handle B is stamped out of one and the same piece of sheet metal.
By this means a frying pan is obtained, the interior and exterior surfaces of which
are perfectly smooth (there being no rivets required for securing the handle), so that
the same can be easily cleaned. When the handle of a pan is secured to the bowl
in the usual manner by means of rivets the rivets in some cases do not fit their holes

through said rivet holes and thus is liable to ignite. Impurities, moreover, are
liable to lodge between the handle and the bowl at the point where they are joined
together and hence it is exceedingly difficult to keep a frying pan of the ordinary
construction in a clean state. These disadvantages are obviated in the improved
pan.
In order to impart to the handle of the pan the requisite strength the same is
provided with vertical flanges a, a, which extend from the top edge of the bowl
..along the edges of the handle. It will be seen that in order to break the handle
these vertical flanges have to be broken edgewise and it will take considerable force
to accomplish this result. Said flanges particularly serve to strengthen the part
forming-the-junction-between-the-handle-and_the_bowl,_and_to_render_such part
capable of sustaining any weight that may be placed in the pan without liability of
its bending or breaking.
In order to cut out the blanks of the frying pans to the best advantage the
length of the handle is made equal to the diameter of the bowl, and the blanks
marked off on a sheet in the manner shown in Fig. 4. By examining this Figure
it will be seen that the only waste which occurs is at the ends of the sheets, whereas
if the blanks for the bowls and those for the handles are cut out separately con-
siderable waste occurs between the adjoining circles of the blanks for the bowls,
and the handles have to be cut out besides, and in addition thereto more stock is
required for such handles since they have to be made long enough to form flanges
which are afterwards rivetted to the bowls.
In the manufacture of the improved pans the labor of rivetting is saved. The
pans can be easily packed up in a small compass since they "nest" to perfection,
which is not the case with frying pans in which the handles are rivetted to the
bowls.
The letter C designates a ventilated covering plate attached to the handle of the
pan. This covering plate may be arranged to extend the entire length of the
handle B, or through only a portion of its length, as may be found most expedient.
Air is admitted beneath the covering plate C primarily through openings d, d,
one of these openings being formed at the extreme inner end of the covering plate,
while the other is located near the outer end thereof. It is preferred to form these
openings d, d', by simply leaving the edges of the covering plate unfastened at the
proper points and slightly cutting out such free edges.
In order to attach the covering plate C to the handle B the opposite edges of the
plate are bent around the flanges a, a, of the handle, as shown in Fig. 3.
In the outer portion of the handle B is formed a hole F, and at a point opposite
to this hole in the covering plate C is formed a corresponding hole G, these two
holes thus registering with each other. The opening d in the covering plate is
formed next to the hole G so as to communicate with the atmosphere through the
same.
By the covering plate C a person's fingers are protected against injury in grasping
the pan handle, the covering being cooled by the air circulating through the
openings d, d, while the flanges a, u, on the edges of the handle are overspread
thereby. The flanges a, a, when combined with the covering plate C have the effect
of producing an enlarged space between the handle and the plate. The holes F, G,
permit of banging up the pan when not in use, and by arranging the opening d¹
next to said holes the extreme end of the covering plate C may be bent around the
end of the handle. In some cases holes fare formed in the covering plate C near
its opposite ends for the purpose of increasing the effect of the openings d, d'.
