Improvements upon Fire Grates, Sioves, &c. 265 
outfide of the houfe, if carried to a cellar, larder, ftair-cafe, 
or any lumber-room, the fame end will be gained; with this 
further advantage, that fuch cellar, larder, &c. will thereby 
be well ventilated, and prevented from acquiring or retaining 
any unhealthy or difagreeable {mells,’ 
The form of the grates may be varied indefinitely ; but the 
one we are about to defcribe anfwers the purpofe fo well, and 
is at the fame time capable of being made, by the aid of a 
good architect, fo highly ornamental to any apartment, that 
our readers will fully comprehend the facility with which it 
may be accommodated to cir@&mftances. 
Fig. 1, (fee Plate V & VI.) reprefents a grate of the improved 
conftruction, and Fig. 2 is a fection of it. The air that main- 
tains the combutftion is fupplied through the pipe or tube A, 
(Fig. 2 and Fig. 4,) or from between the under-ceiling and 
floor as before-mentioned, from which it pafles up. by the 
back or fide of a drawer B, Fig. 2, according as it is moft 
convenient to bring it up by the one or the other; the back 
however is preferred, where convenience admits of it. The 
front of this drawer, in its place, is feen in Fig. 1, at C. 
The intention of this drawer is to receive the afhes that fall 
from the bottom bars of the grate, feétions of which are 
reprefented at DD, Fig. 2. The afhes, as they fall from 
the bars, firike again{t the fides of the internal cavity E, 
and then are carried by their own gravity through the narrew 
part F, and fall into the drawer. This part of the con- 
firuction may be eafily underftood by conceiving it to be an 
hollow vafe, as it actually is, with a drawer in its pedeftal 
or bafement, and having a grate over it, on,which the fire 
refts. The valve, door, cock, or other contrivance by 
which the external air is admitted or excluded, may be 
either in the neck F of the vafe, or in the air-tube, or in 
the drawer B or C, or, which is preferable, in. the cavity, 
behind the drawer, the pedeftal or bafement of the vafe 
being made large enough to admit of fuch cavity. Various 
confiructions may be reforted to; but that reprefented in 
Fig. 3, (which is a ground-plan of a proper chimney for 
fuch a grate, and in which a bird’s-eye view of one half of: 
the grate may be feen in its place, while the other half repre-
