4 Claims. (Cl. 126-245)
This invention relates to heaters, particularly
those for burning solid fuels, and has for its prin
cipal object to provide a heater structure which
facilitates handling of the ashes that result from
burning of the fuels.
Other objects of the invention are to provide
and rear walls 3-4 and side walls 5-6 that are
?anged inwardly along the lower edges as at 'i
for support on a base 8, a bottom plate 9 being
inserted between flanges In on the base and the
?anges ‘I as best shown in Fig. 3 to form the floor
of an ash compartment ll. Supported by the
walls of the casing in upwardly spaced relation
to the floor 9 is a grate basket 12, carrying a grate
a heater with a readily operable drawer for con
taining the ash receptacle; to provide a heater
with a unitary ash drawer and ash compartment
l3 which forms a top of the ash compartment and

the rear wall of the ash compartment spaced
slightly below the grate basket and the ends
thereof supporting the rear ends of track mem

are of substantially channel shape in that they
have inwardly facing webs 4| provided with lat-_
eral ?anges 42 and 43 which provide upper and"
lower guides for drawer supporting rollers 44 and
65 later described. The track members incline
upwardly toward the front wall-3- andvthe for- ‘
ward ends terminate short of the door frame to
provide gaps 46 to accommodate the rollers when
they are to be removed from‘the tracks ‘for pur
poses later described.
In order to provide stops for the rollers the
lower ?anges 43 of the tracks have depressions

In order to support the front of the drawer
the bottom rail of the door frame 25 carries ears
‘H for journaling rollers 12 that are engaged with
inset faces 73 of the side members of the drawer
as shown in Figs. 3 and 4.
In order to lock the drawer in retracted posi
tion and at the same time secure the door 59, the
respective sides of the door carry shafts ‘I4 and
'l5‘provided'with handles 16 on the outer ends
and lugs 11 on the inner ends which are adapted
to engage keepers l8 projecting from the side
members of the door frame as shown in Fig. 4.
Combustion supporting air is admitted to the ash
pit through an opening 19 provided in the front
panel of the door and which is closed by a shut
ter??pivotally mounted on a cap-screw 8| as
shown in Fig. ll, the shutter being provided with
a knob or lug 32 on the outer side thereof to
facilitate movement thereof to and from open
position. The ash receptacle is best illustrated
in arms 48 that are attached to lugs 49 depend
