I THOMAS CARTWRIGHT GREAVES of 21 Ducie Street Manchester in the County of
Lancaster, Commission Agent do hereby declare the nature of this invention to be as
follows
My said Invention relates to an improved apparatus for roasting potatoes and
consists of an outer vessel or cylinder of any suitable material but made preferably of
sheet iron closed at one end and open at the other. Into this vessel I introduce a
removable cage or holder within which the potatoes are placed. The said cage or
potato holder is cylindrical like the aforesaid outer vessel and consists of a lid which
fits into or over the open end of the said outer vessel. The cage is of about equal
length with the outer vessel the inner end consisting of a ring or flange between
which and the aforesaid lid is supported the series of bars or the perforated shell or
cylinder of wire mesh or other suitable heat permeable material composing the
potato holder or cage. When the cage is composed of bars, sufficient space is left
between the bars and the interior of the outer vessel to permit of the circulation of
heat and to prevent the potatoes from coming in direct contact with the outer vessel;
but in all cases I prefer that a space should be left between the periphery of the cage
and the interior of the outer vessel. The lid of the cage is furnished on the outside
with a handle by which the cage can be introduced into, withdrawn from, or rotated
within the outer vessel. The outer vessel is also provided with a handle by which it
can he placed upon and removed from the fire. When the apparatus is to be used
the potatoes are introduced into the cage through the open end and the cage is then
pushed into the aforesaid outer vessel which is then placed upon the fire or otherwise
subjected to the action of heat. To cook the potatoes equally well on all sides the
cage or holder is turned in the outer vessel from time to time during the cooking
operation until the contents are sufficiently done, after which the cage is withdrawn
and the potatoes removed. The bottom of the outer vessel may if desired be

invention lies in the removable and revolvable potato holder or cage, the said cage
might be combined with any suitable heater or oven other than the hereinbefore
referred to outer vessel and such heater or oven might be applied to, combined with,
or formed in a cooking range, fire or stationary or portable stove whether heated by
coal, gas or other means. The lid of the cage or the end of the outer heating vessel
might in some cases be formed with a sliding or hinged door through which one or
more potatoes could be removed at a time.

page_text: I THOMAS CARTWRIGHT GREAVES of 21 Ducie Street, Manchester, in the County
of Lancaster, Commission Agent do hereby declare the nature of this Invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement and accompanying drawings :-
My said Invention relates to an improved apparatus for roasting potatoes and
will be best understood when described with reference to the accompanying sheet of
drawings:-
Fig. 1 is a vertical longitudinal section of my improved potato roaster. Fig. 2
being an end view of the same. The apparatus consists of two distinct and separable
parts namely an outer cylindrical vessel a of thin sheet metal closed at one end and
open at the other and a cage or holder b which contains the potatoes and which can
be introduced into and removed from the outer casing a. The said cage or potato
holder bis cylindrical like the aforesaid outer vessel a and consists of a series of bars e
which are pitched at a suitable distance apart and extend between the cover or
removable end d and an annular end ring e a portion of which is shown at Fig. 1ª.
The bars c are rivetted or otherwise fixed to the cover d and the ring e so as to form
the cage b. The cage is of about equal length with the outer casing a and the bars c
are so arranged that sufficient space is left between them and the interior of the outer'
vessel to permit of the circulation of heat and to prevent the potatoes from coming in
direct contact with the interior of the vessel a. The cover or end d of the cage is
furnished with a handle f by which the cage can be introduced into, withdrawn from
or rotated within the outer vessel a. The said outer vessel is also provided with a
handle g by which it can be placed upon and removed from the fire. When the
apparatus is to be used the potatoes are introduced into the cage through the annular
ring forming the open end and the cage is then pushed into the outer casing a which
is then placed upon the fire or otherwise subjected to heat. To cook the potatoes
equally well on all sides the cage or holder bis turned in the outer vessel a from time
to time during the cooking operation until the contents are sufficiently done, after
which the cage is withdrawn and the potatoes removed. The bottom of the outer
vessel a may if desired be strengthened or made of greater thickness than the rest of
the casing so as to resist the action of the heat. The casing a may if desired be furnished
with feet to steady it on the fire or it may be made of the waggon shape shown at Fig. 3 or
a separate stand may be made to receive the cylindrical roaster as shown at Fig. 3° the
said stand being suitable for placing on a hot plate or over a gas or other burner or
fire the walls of the stand confining and concentrating the heat on the roaster bottom.
Instead of making the revolvable cage of open bars as shown it might be made
of wire gauze or of woven or intertwisted wire or perforated metal or of other

page_text: metallic fabric or material which will permit the heat to circulate freely through and
around the cage and contained potatoes. The said revolvable cage or potato holder b
is the gist of my invention and I might combine the said cage with any suitable
heater or oven other than the herein before described outer vessel ä, for example a space
or casing to receive the cage might be applied to, combined with or formed in a
cooking range or stationary or portable stove whether heated by coal, gas or other
means. In Fig. I have shown a portable potato stove suitable for street use. The
stove has a fire box closed by a suitable door. A casing is formed above the fire
box and the cage a is pushed into the casing from the front. The products of
combustion escape through the chimney i. In the upper part of the stove are
drawers kk, which may be utilised to contain potatoes which have been roasted in the
cage d and may also contain salt, pepper and condiments. Where the stove is not
heavy it may stand on feet and be transported from place to place by the handle l.
If too heavy to be lifted it may be mounted at one end on wheels m. m and be furnished
with removable shafts entering sockets n. secured to the sides of the stove.
supply of fuel could be carried in a basket suspended to the bottom of the stove. In
the latter type of stove or in other types, to prevent the necessity for withdrawing the
cage entirely from the stove or casing I might binge a portion of the bars so as to
form a short door in the side of the cage through which one or more of the
contained potatoes could be removed-or I might form a sliding or hinged door in
the front cover of the cage. In such cases the end of the cage need not necessarily
be open.
A.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
(1) The improved potato roaster consisting of an outer case a and inner removable
and revolvable cage or holder of the construction and substantially as hereinbefore
described and shown.
(2) In apparatus for roasting potatoes the cage or holder & having its sides composed
of open bars or of heat resisting and permeable fabric or material and capable of
being introduced into and turned in a casing, oven cooking range or stove substantially
as described and shown.
(3) The portable potato roasting stove shown at Fig. 4 and fitted with a revolvable
cage of open bars or open work and having a side or end door for the removal
of potatoes singly and from time to time substantially as herein before described and
shown.
