(Cl. 219-19)
My invention relates to electric cooking devices,
and particularly to electric toasters of the do
mestic type.
An object of my invention is to provide a rel
5 atively simple and compact multi-slice toaster.
Another object of my invention is to provide
a vertical toaster having a combined toaster
carrying and bread-slice-raising means.
' Another object of my invention is to provide
10 a toaster-carrying means that shall not becomev
hot during use of the toaster.
Another object of my invention is to provide
a novel heating-element spacing-and-supporting
_ means in an electric toaster.
Other objects of my invention will either be
apparent from a description of one form of de
vice embodying my invention now preferred by
me, or else appear from such descript on.
In practicing my invention, I provide a hollow
‘0 sheet metal base having a, dished crumb tray
3 but showing a different position of the bread
slice raising means, and,
Fig. 5 is a, fragmentary view in horizontal sec-.
tion taken on the line V-V of'Figni.
A vertical toaster designated generally by the 5
numeral H, includes an upwardly dished base
l3, which may be made of sheet metal, the up
per surface l5 of which has a somewhat smaller
area than the lower portion thereof in order to
provide a pleasing appearance. The hollow base
I3 is provided with a pair of longitudinally ex
tending openings l1 and I9 therein located in
termediate the sides and the longitudinal center
line thereof, and for a purpose to be hereinafter
more fully described.
I provide a pair of vertically-extending end
plates 2|, only one of which is visible in Fig. l
of the drawings, and it is to be understood that
a similar end plate 2! is located‘ adjacent to the
left hand end of the base. Each end plate ‘M 20
is provided with a pair of spaced vertically-ex
tending openings 23 therein, these being shown

be hereinafter described, and while I may use
a single sheet of mica extending from top to
bottom, I have illustrated two such strips of mica
each substantially one half of the total height,
this being done in order to reduce the cost of
the heating elements. Two such pairs of mica
sheets are located side-by-side in each heating
element. A resistor conductor designated gen 40
erally by numeral 33, is operatively supported
moved vertically upwardly in the openings in the by the respective plates 21, 29, and 3| of electric
end plates by a combined bread-slice-support-V insulating material as by being wound in recesses
actuating and toaster-carrying means, which or notches 'in the lateral edges of the respective
means is pivotally connected by a linkage struc
‘15 ture with the bread-slice-supports. A casing
structure encloses the heating units, bread racxs,
end plates, the bread slice supports and the link
age, the top portion of the casing having depend
ing ?ange portions overlapping the upper edges
"" of the bread racks.

3! are located thereagainst on the inner surface
only while this resistance conductor is located on
both sidesof plate 29 to thereby provide in‘ef

in juxtaposition to each other so that where three
heating units are provided, two slices of bread
may be toasted at the same time without ap

the operator desires to ascertain the progress of 30
the toasting action, he need only press down

the top portion of the casing so the visual ins'pec- -.,

easily made. When the slices of bread have, been
toasted to the desired degree, pressure on the bar
93 or 95 or on both of them will raise the toast as

possible for vthe toasting operation I may provide‘
the side plates I33 with a layer I63 of sheet
asbestos, secured against the inner surface there
