IMPROVEMENTS IN FIELD OR CAMP OVENS APPLICABLE ALSO TO OTHER OVENS
Year: 1885

page_text: I JOHN JAMES MELLOR, Lieutenant Colonel 1st Volunteer Battalion Lancashire
Fusiliers of Whitefield near Manchester in the County of Lancaster, do hereby
declare the nature of my Invention for IMPROVEMENTS IN FIELD OR CAMP OVENS
APPLICABLE ALSO TO OTHER OVENS to be as follows:-
As hitherto constructed these ovens have required to be taken to pieces in case
the bottom plate became burnt out and so involved considerable time and expense
in repairs.
My improvements consist in constructing this description of oven with outside
flanges and in having the bottom plate to slide in a suitable groove or channel
formed between the oven and the fire-box with a projecting plate of metal between
the two surfaces or such bottom plate can extend across the bottom to the outside
of the flanges and thus be secured in position by the same bolts which secure the
oven to the fire box. Facility is also afforded by this mode of construction to
form the sides and top of the oven body all of one sheet of metal.

page_text: My improvements consist in constructing this description of oven with outside
flanges and in having the bottom plate to slide in a groove or channel formed
between the oven and the fire-box, with a projecting plate of metal between the
two surfaces or such bottom plate can extend around the bottom to the outside of
the flanges and thus be secured in position by the same bolts which secure the oven
to the fire-box.
Facility is also afforded by this mode of construction to form the sides and top
of the oven body all of one sheet of metal.
In order that this my said invention may be the more readily understood and
carried into practical effect I have hereunto annexed a sheet of drawings illustra-
tive of my improvement and will now proceed to described the same with the
assistance of the various Figures and letters of reference marked thereon.
Fig. 1 is a side exterior view Fig. 2 an end sectional view of a camp oven
embracing my improvements Fig. 3 is an enlarged sectional view of part of Fig. 2
shewing the construction of the groove into which the bottom plate slides.
Ն
In all the views a represents the body of the oven which is of the usual construc-
tion but is provided with a flange projecting outwards all round the bottom as
illustrated and resting upon the projecting plate of metal or intermediate flang c.
This plate c again rests upon the top of by preference the cast-iron fire-box d
which in accordance with this invention is constructed with a rebate or groove e
in which slides the loose bottom plate f, g is the usual cast iron saddle plate for
protecting the bottom of the oven. This construction permits the oven body and
fire-box to be bolted together by the same bolts which pass through all the
flanges as illustrated.
It will thus be apparent that in case the bottom plate f becomes burnt out or
otherwise injured it can be drawn out of its groove and be repaired or replaced
without unscrewing any bolts and without taking the oven to pieces-Or if pre-
ferred the bottom plate may extend around the bottom to the outside of the flanges
.and thus be secured in position by the same bolts which secure the oven to the fire-
box. Facility is also afforded by this construction to form the sides and top of
the oven body in the small sizes of ovens all of one sheet of metal.
Having thus particularly described and ascertained the nature of my invention
I declare that what I claim is
Constructing camp ovens with outside flanges and with a sliding bottom plate
or its equivalent substantially as and for the purpose hereinbefore described and
illustrated on the accompanying drawing.
