PROVISIONAL SPECIFICATION.
Improvements in Bakers' Ovens.
We, JOHN VICARS, THOMAS VICARS, and JOHN VICARS the Younger, all of
56, Seel Street, Liverpool, in the County of Lancaster, Engineers, do hereby declare
the nature of this invention to be as follows:-
The object is to so construct bakers' ovens having both top and bottom heat that
the distribution of the said heat is readily regulated and controlled and more
effectually utilized than heretofore.
The invention consists essentially in constructing the said ovens with flues both
above and below connected to each other, to the furnace, and to air openings in
such manner that by the use of dampers the products of combustion and heated
gases can be directed above and below the ovens, and air can be admitted into the
flues and furnace, dampers being so constructed and arranged that any of the above
objects may be obtained as required.

COMPLETE SPECIFICATION.
Improvements in Bakers' Ovens.
We, JOHN VICARS, THOMAS VICARS, and JOHN VICARS the Younger, of
56, Seel Street, Liverpool, in the County of Lancaster, Engineers, 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 :-
The object is to so construct bakers' ovens having both top and bottom heat
that the distribution of the said heat is readily regulated and controlled and more
effectually utilized than heretofore.
The invention consists essentially in constructing the said ovens with flues
both above and below connected to each other, to the furnace, and to air openings
in such manner that by the use of dampers the products of combustion and heated
gases can be directed above and below the ovens, and air can be admitted into the
Hues and furnace dampers being so constructed and arranged that any of the above
objects may be obtained as required.
DESCRIPTION OF THE DRAWINGS.
Fig. 1. is a horizontal section at the line A, A, Fig. 4.
Fig. 2. is a longitudinal vertical section.
Fig. 3. is a transverse vertical section at B, B, and
Fig. 4. is a view along the line C, C, part being in elevation and part in section.
a is the oven, b, flues above, and e flues below the oven, d, firegrate and furnace,
eways leading from the furnace to the flues c. f, ways leading from the furnace to
the flues by, dampers for the ways e. h, dampers for the ways fi, air valves,
j, ways leading from the flues c to the furnace d. k, ways leading from the flues b
to the furnace d. l, m, dampers and valves. o, way leading from the oven to the
waste flue r, by means of passages p, q. s, damper.
It will be seen on reference to Fig. 2, that products of combustion are passing
in to the flue b, above the oven and thence to the chimney and that air is passing
by the flue e to the furnace. It will be obvious that by adjusting the dampers,

page_text: the above action may be reversed, or the products of combustion or air may be
made to pass through both flues b, c. When both flues b, c, are shut off from the
furnace the products of combustion pass by a way t, to the chimney. Steam from
the oven passes by the way to the waste flue. When the oven is being drawn,
the way p, is opened to the chimney.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is: :-
Constructing ovens with flues, ways, dampers, and valves substantially as herein
set forth.
