page_text: months next and immediately after the date of the said in part Letters
Patent, as, reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Jubber, do hereby declare the nature of my said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, and by the Drawings therein
referred to and hereunto annexed; that is to say :-
My Invention relates to Certain Improvements in the Construction of
Kitchen Ranges and Apparatus for Cooking, and consists in a novel and
peculiar arrangement and combination of the parts connected therewith,
whereby great economy in fuel is effected, and the process of cooking rendered
less laborious to the attendant and more effective than by the use of the
apparatus hitherto employed for that purpose. And in order to explain the
said improvements as completely as possible, I will proceed to describe the
arrangement of parts which I consider well calculated for carrying out my
said Invention, and which will be found to answer extremely well'

page_text: one side of which vertical plates B, B, are firmly secured (by rivetting to the
back) for carrying the mechanism employed to actuate the vertical and
horizontal spits, the middle compartment C forming a metallic flue, at the
upper part of which an ordinary smoke jack D is situated (a detached view of
the same being shewn at Figure 4), for imparting motion to the horizontal
axis E, upon each end of which mitre wheels F, F, are keyed, taking into
corresponding wheels G, G, motion being imparted from thence to spur
wheels H, H, which are likewise keyed upon vertical axes I, I, situated in
top and bottom plates K, K, as represented by the Drawing. L, L, collars
screwed upon or otherwise connected to the lower ends of the vertical axes.
Into these collars I insert and make fast one end of a fine wire rope M, M
the other end being similarly secured in collars formed at the upper ends of
the vertical spit carriers N, N. O, O, rack plates (see detached Figure 5*)
fixed to the sides B, B, to enable the cook to place the spit at any required
distance from the fire. P, P, the grate, extending from back to front of the
frame or casing A, A, and furnished with a sliding cheek Q, worked by a rack
and pinion R, S.
my
The arrangement and construction of this part of invention forms
an important feature in these improvements, the quantity of radiating surface
of the fire exposed and available for the purposes of cooking being considerably
augmented by constructing the grate in such manner as that three sides of the
fire are beneficially employed (as represented by the Drawing). T, a boiler
fixed to the front of the grate, and furnished with steam cocks, which may be
used as required, the surplus steam passing off through an opening X,
formered at the upper part of the boiler, as shewn, and from thence through
the fire, or otherwise, as may be found most convenient. U, a hot plate,
situated at the front of the framing A, heat being furnished to the same from
the fire V, an opening W being made therefrom into the grate P. X, an air
Hlue, situated in front of the hot plate. The air which passes through a
vertical perforated pipe Y to supply the fires is prevented from passing in any
other direction than through the under side of the fire by the hinged plates Z
situated at each side of the grate, the quantity of air admitted thereto being
regulated by a damper a. b, b, slides for carrying dripping pans.
Figure 5 shows another arrangement of hot plate, by which the necessity
for a separate fire is dispensed with, and the heat from the water and steam
contained in the boiler employed to effect the same. Since, however, an open
fire may occasionally be found necessary, provision is made for this purpose
at c, a damper d being situated in the flue leading therefrom, which communi-
cates with the main flue, as represented.

page_text: The operation of the apparatus is as follows:-The fire being previously
lighted in the grate P, and the spits charged with meat, motion will be
imparted to the jack (by the ascent of rarified air), and from thence to the
wire ropes or rods to which the vertical spit carriers N, N, are attached. The
borizontal spits receive motion from a wire rope passing over a rigger 1, fixed
upon the axis-e, and from thence over riggers 2, 3, 4, 5. And in order that as
much heat as possible may be rendered useful, I employ sliding doors f, g, h,
(furnished with counterbalance weights) which it will only be found necessary
to open when requiring to feed the fire or notice the progress of cooking. It
is obvious, also, that instead of the peculiar arrangements herein-before
described of a boiler and hot plate in front of the fire, the boiler might be
placed at the back, and the front of the fire used as an open fire without
departing from the principal feature of my Invention, namely, the rendering
the fire at the two sides available for the purposes of cooking, às above
described.
Having now described the nature of this part of my said Invention, and in
what manner the same is to be performed, I wish it to be understood that I
do not claim the exclusive use of any of the separate parts above mentioned
and referred to, except so far as the same may be used in combination for the
purposes of my said Invention, one part of which I declare to consist in the
construction of a kitchen range or cooking apparatus, whereby the heat
radiating from the fire exposed between the bars or the two sides may be
rendered available for the purposes of cooking.
In Sheet, 2 the Drawings represent a more simple arrangement and con-
.struction of apparatus, possessing all the advantages of that represented in
Sheet I., but being less in size is more portable, considerably less expensive,
and better calculated for general domestic purposes. In place of the ordinary
smoke jack shewn at Figure 4 (Sheet I.), I employ a series of fans i, i,
mounted upon the horizontal axis k, k. At one end of this axis a worm / is
keyed, taking into worm wheels m, secured in their proper position by collars
formed thereon, working in brackets n, n. These worm wheels actuate the
vertical spits, which are similar to those referred to in Sheet I., with this dif-
ference, that by this arrangement only one set of spits is employed, an oveno,
and hot plate p, and hot closet p¹ being substituted in the place of the second
set. A set of horizontal spits may be employed in the apparatus by the appli-
cation of arrangements similar to those already described in the first part of
my Invention. In order that the heat arising from the fire may be made to
act upon all sides of the meat, the oven is furnished with revolving shelves q,
a fireplace, having a flue communicating with the chimney, and furnished with

page_text: a damper, by which a separate fire may be used when necessary, the apparatus
being provided with doors similar to those used in the former apparatus, and
being for the same purpose. As the front of the fire is not furnished with a
boiler, a sliding door is substituted, so that this part of the fire may be
rendered available when required.

Having now described the nature of this part of my said Invention, and in
what manner the same is to be performed, I wish it to be understood that I
do not claim the exclusive use of any of the separate parts of the apparatus
above mentioned, except when the same are used in combination for the
poses of my said Invention, another part of which I declare to consist in the
construction of a kitchen range or cooking apparatus, whereby the heat radi-
ating from the fire exposed between the bars on one side may be rendered
available for the purposes of cooking.
In Sheet 3, Figures 9, 10, 11, s, s, represents a rectangular casing or box
of metal, at one part of which a furnace t, t, is formed, the fire of which
imparts heat to water contained in the cylindrical boiler u, which is provided
with the necessary means for escape of steam and drawing off the water when
required, an arrangement being likewise made for ascertaining the quantity of
water in the boiler by the application of an ordinary water guage v, at the top
of which a funnel w and cock are fitted for the purpose of filling the boiler, the
whole being firmly fixed to the casing,as represented by the Drawing. Imme-
diately over the boiler u a second furnace x is situated, being for the purpose
of imparting heat to the hot plate y, and transmitting it from thence to an
oven, situated at the top of the hot plate, as represented by the Drawing.
This oven may be removed when required to use the hot plate. I would here
remark, that from the portability of this oven it can, with a trifling modifica-
tion, be adapted to an ordinary range or grate. The furnace t, t, is constructed
with flues (the course of which is represented by the arrow's flight), and com-
municates with a descending flue a¹, by holes formed in the sides of the upper
furnace u at **, an opening being made at b¹ communicating between the
furnace and descending flue. In Figures 12 and 13 similar letters to
those used in the foregoing Figures are placed upon corresponding parts of
the apparatus.
Having now described the nature of my said Invention, and in what
manner the same is to be performed, I wish it to be understood that I do not
claim the exclusive use of any of the separate parts of the apparatus lastly
above described, except when the same are used in combination for the pur.
poses of my said Invention, another part of which I declare to consist in the
