Power's Portable Oven is here given to the scale of one inch to the foot,
and 2 feet deep. Figure 1 represents the oven detached, so.constructed as to
be set over a laundry or any other small stovė. Fig. 2 represents the oven
and hot closet complete. Fig. 3 is the inside view of Fig. 2. A, the hot
closet, which is gradually heated to any degree by means of the large valve
in the chimney G. F is the splitter, so called because it divides equally the
heat of the fire, and throws it up the flues a, a, & heats both the oven and
hot closet. In case the splitter should retain too great a heat for the oven B,
b is a valve for the reception of air, which may be regulated to option. H is
the small valve (Fig. 8) made round and fixed about 2 inches from the front
of the oven, with holes in the sides to secure it from the soots falling into the
oven. The use of this valve is in case any nauceous scent may arise from
baking, a currency of air passes through the ventilator c, and carries the scent
into an open chamber I. The large valve is fixed about 12 inches from the
extremity of the oven. K is the scraper, a piece of iron carried over the hot
closet, which, when pulled out by the two handles d, d, scrapes the soot which
adheres to the top, and carries it down the flues into an open chamber L, and
is swept out of the doors E, E, by a brush. C, the furnace, which is about 8
inches, square at bottom; and regularly passed up to the sides, front and back.
è, e, è, e, are baking tins. D is the cinder hole. Fig. 4 is a baker's, oven,
similar in construction to the furnace one, but with these exceptions:-It is
4 feet long, 2 deep, & 24 high, with three ovens, 2 of which are regulated
by ventilators at bottom. L, L, is an open chamber to prevent too great
or sudden heat from the splitter. Fig. 6, the ventilator, which is turned
by the handle ef, to enable g to admit. or secure any quantity of air.. Fig. 7,
the large valve, which is placed in the chimney G, which acts as a damper to
graduate the heat to the hot 'closet. It is made with sheet iron, like the
oven, the size of the oven pipe, and turned by a strong thick wire, handle
in its centre. Fig. 8 is on the same construction, except being closed at
top, and holes in the sides, already specified, and rendered, when done, air-
