I JULES MASON of 6 Arthur Street Chambers King William Street in the City of
London, Merchant do hereby declare the nature of this invention (a communication
from abroad by Jacques Eugène Jean Louis Mounié of 21 Rue de Moscow, Paris,
France, Engineer) to be as follows:-
This invention relates to improvements in the continuous oven with endless
travelling sole for which Letters Patent were granted to Alexander Melville Clark
dated July 8th 1882 No. 3251, and the invention has for its object to double the
working capacity of the oven without materially increasing the cost of fuel or labor.
The oven therein described is in the form of two long arches one above the other
having the floors, sides and roof or any of them constructed of heating flues, the
arches being traversed longitudinally by an endles chain of slabs supported by rollers
running on a railway and passing round polygonal drums or tumblers at the ends of
the oven.
The object of the present invention is to enable both the upper and lower members
of the chain to be utilized as a travelling sole upon which the bread &c. is baked so
that the working capacity of the oven be doubled and for this purpose the arches are so
arranged and heated as to bake at the same speed, and the chain of slabs is so arranged
as to work equally well either side uppermost. The tumblers, around which the chain
passes, are placed at a sufficient distance from the ends of the arches to give access to
the upper and lower members of the chain, the dough being placed on the inwardly
travelling member of the chain and the baked bread removed from the returning or
outwardly travelling member simultaneously at both ends of the oven.
The heating flues of the arches instead of being constructed of tubes as described in
the previous specification may be made of large slabs of refractory material and the
driving gear of the tumblers by which the chain is caused to travel along is provided
with change gear to enable the time occupied in passing through the oven to be varied
according to requirements.

Improvements in Baking Ovens.
I, JULES MASON, of 6 Arthur Street Chambers, King William Street, in the City
of London, Merchant, do hereby declare the nature of this invention (a communication
to me from abroad by Jacques Eugène Jean Louis Mounié, of 21, Rue de Moscow,
Paris, France, Engineer,) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This Invention relates to improvements in the continuous oven with endless
travelling sole for which Letters Patent were granted to Alexander Melville Clark,
dated July 8th 1882 No. 3251; and the invention has for its object to double the
working capacity of the oven without materially increasing the cost of fuel and with
little extra labor. The oven therein described is in the form of a long arch having
the floor, sides, and roof, or any of them, constructed of heating flues, the arch being
traversed longitudinally by an endless chain of slabs supported by rollers running on
a railway and passing round polygonal drums or tumblers at the ends of the oven.
In a modification of the oven therein described, two superposed arches are described a
member of the chain passing through each, but only one of them being available for
baking, the lower member running idle.
The object of the present invention is to enable both the upper and lower members
of the chain to be utilized as a travelling sole upon which the bread etc., is baked, thus
doubling the working capacity of the oven, and for this purpose the arches are so
arranged and heated as to bake at the same speed and the chain of slabs is so arranged
as to work with a charge of dough upon both the upper and lower members. The
tumblers around which the chain passes, are placed at a sufficient distance from the
ends of the arches to give access to the upper and lower members of the chain the
dough being placed on each member of the chain at its inwardly travelling end and
the baked bread removed therefrom at the outwardly travelling end, these two
operations being performed simultaneously at both ends of the oven. The heating
flues of the arches instead of being constructed of tubes as described in the previous
specification are made of large slabs of refractory material and the driving gear of
the tumblers by which the chain is caused to travel along, is provided with change
gear to enable the time occupied in passing through the oven, to be varied according
to requirements.
Reference is to be had to the accompanying drawings forming part of this
specification, in which figure 1 is a part longitudinal section of the oven. Figure 2
is an end elevation. Figure 3 is a plan, and figure 4 a cross-section, of part of
the endless travelling sole. The same letters of reference indicate the same parts in
all the figures.
The oven which is about fifty feet in length (more or less) is formed of two
superposed arches A B the hollow floors a b of which are constructed of slabs of fire
brick so arranged as to form heating flues, each arch being about twenty-eight
inches wide by ten inches high (more or less). The crown of the arch A may also

page_text: be constructed with a flue a', all these flues being in connection with a furnace at
one end and with a chimney at the other. C is the endless travelling sole, each
link or member of which is constructed of a fire clay slab c fixed in a frame c¹
provided with knuckles c² which take hold of joint pins D whereby the several links
composing the chain are jointed together. The joint pins D project beyond the
sides of the frames and carry rollers d, which run on railways E fixed along the
arches A B and are adapted to support either member of the chain under the load,
both sides of the chain being made alike and equally well adapted to serve as a sole
for the purpose of baking bread. The endless sole passes round tumblers F each
mounted in a frame G situated about four feet (more or less) beyond the open ends
of the arches A. B. The faces of the tumblers correspond in dimensions to the links
of the chain, and one of these tumblers is driven by any suitable gearing and the
chain moves through the oven at a speed suited to the size of loaf to be baked. For
a loaf two pounds in weight for instance, the speed would be such as to carry the
loaf through the oven in about thirty-two minutes more or less, the speed being
varied for loaves of other weight, so as to vary the time of baking accordingly, as
will be readily understood by any ordinary baker.
Assuming the chain to travel in the direction of the arrows, the dough would at
the one end of the oven, be placed on the ingoing member of the sole at and the
baked bread removed from the outcoming member at y, the baked bread being
removed from the upper member and fresh dough placed on the lower member at
the opposite end of the oven, these operations being simultaneous and continuous at
both ends.
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 :-
The herein described improved continuous oven, constructed of two superposed
arches with an endless chain of slabs passing through each and round tumblers at
the ends, both arches having flues in the floors, constructed of fire clay slabs and
being thereby heated to an equal extent, and both members of the sole being used for
baking simultaneously, whereby the working capacity of the oven is doubled, all
substantially as specified.
