on frame 2|, and thus releasably retains the frame
prising a cooking compartment, a frame mounted
in inner position.
In operation of the stove, there is seldom any
for movement into and out of said compartment,
occasion to remove the broiler frame 2| from
the cooking compartment ll. During broiiing,
however, there is likely to take place a suf?cient
amount of spattering so that frequent cleaning
of ‘the broiler parts is necessary. The broiler
liner 22, built inaccordance with the present
invention, can be readily removed for such clean
40 ing, and it is also to be noted that broiler liner 22
‘affords protection to the withdrawal mechanism,
so that these parts seldom require attention. To
remove liner 22, the frame 2| is withdrawn to its
outer position, and closure 24 is swung about its
hinges to open position. Then a lifting motion,
applied as to the forward ends of side walls 44,
will separate pins 49 from notches 35. During
such lifting, the liner pivots about side supports
50, resting on the tops of frames 30, and rear
support 52 moves downwardly out of contact
.50 with rear cross piece 32. After the forward end
‘ has been elevated sufficiently to clear the forward
parts of the frame, the liner may be pulled for
,wardly a short distance and-then lifted com
55 pletely free of the frame structure. To replace
the liner, the procedure is reversed, and the sup
ports are so arranged that the liner is guided
easily and quickly to proper operative position.
It will be noted that in the embodiment illus
trated, the proportioning of liner 22 and its as
‘ sociated parts is such that it cannot be lifted out _
of operative position unless closure 24 is first
