31 is also mounted upon this strip but positioned

are in different horizontal planes and so spaced
that there is guiding clearance between them

35 expectedly.
To completely remove the drawer,
the inner end `thereof is raised so that the roller
28 may be moved over the roller 31, and the en
tire drawer may be withdrawn completely.
Mounted in the front member of the drawer is
40 a shaft 52 adapted to be rotated in suitable bear
ings 54 and 55 which are formed in the plates I6
and I8 respectively by punching the same and
bending over the edges of the material to form a
bearing surface. A pinion 5I is ñxed to shaft 52
45 by any suitable means and is engaged by a spring `
detent 56 which is mounted upon the bent over
top surface of the sheet I8. This detent yielding
1y engages the teeth of the pinion and serves to
hold the same in any position in which it is left.
50 A large segmental gear 58 is rotatably mounted
upon a shaft 59, which is carried in similarly
formed bearings in both front and rear walls I8
and 20 of the drawer, and which extends the
entire distance between these two walls. The
teeth of this gear are adapted to engage the pin
ion 5|. Projections 60 are formed at each end of
gear 58 to serve as stop members when they abut
against the pinion .55 in either extreme position
of the gear.
A lever 6I is ñxed to the shaft 59 within the
compartment formed by plates I6 and I8, and is
pivoted at one end to two operating links 62, one
of these links being placed upon each side of the
lever and spaced apart a predetermined distance.
65 The links 62 in turn are pivoted to one of a pair
of pan supporting arms 63, 64, which in turn
are pivoted at 65, 66 to the plate I8. In order

upon the inner surface of plate I8 andl are spaced
therefrom a distance just'suflicient to provide
for the vertical movement of the arms 63, 64 but
will effectively prevent any horizontal movement
or bending of the arms, such as might be caused
by a careless person in forcing the lugs 15 against
the operating arms in positioning the pan within
the drawer.
The mechanism at the inner end of the drawer
is substantially similar to that at the outer end,
with the exception of the operating pinion and

only necessary to provide a lever 8l pivoted to two
operating links A82 which in turn are pivoted to
one of the inner pan supporting arms 83 and 84. ‘ -
These arms are pivoted at 85. 86 to the inner
plate 26 of the inner wall, which is similarly pro
vided with depressions 81, 88 so that the pivot 45
point will not extend into and interfere with the
positioning of the pan. Links,82 are formed with
projections 89 which overlie the intermeshing
gear faces of arms 83 and 84 and perform the
same function as projections 12 at the outer end 50
of the drawer. Reinforcing brackets 9U are also
positioned at the inner end and function in the
same manner as do the brackets 11 at'the outer
end.’ Slots 8| formed in plate 20 provide for guid
ind the pan during its vertical movement.` 4
The operation of the pan elevating mechanism
is as follows: In response to ,a turning movement
o_f handle 50, the pinion 5I causes rotation of a
segmental gear 58 which in turn imparts a rota 60
tional movement to the shaft 56. Levers 6I and
8|, ñxed to shaft 59 cause the movement o_f ’the
operating links 62 and 82 respectively, which in
turn cause the arms 63 and 83 to rotate about
pivot points 65 and 85 respectively. In response 65
to this movement, the arms 64 and 84 are likewise `
caused to rotate the same amount about their

pivot points 66 and 86 respectively. This causes

or down, in the same direction, and to the same

70 depressions 61, 68 are formed in plate I8 of such
a depth that the pivots are indented from the
surface of the plate I8. The arms 63 and 64 are
formed with intermeshing gear teeth 69, 10 at
their adjacent ends and thus it is insured that
75 the two arms will move in unison, for any move
be raised or lowered, the same amount at
every point and hence'is maintained horizontal
throughoutits'extent of vertical movement.

In the arrangement just described, the single
justable handle carried by said wall, a pair of
handle 50 serves two purposes. It provides a
adjustable pan supporting arms formed at ad
jacent ends with intermeshing gear faces, and
convenient means for moving the drawer laterally
of the oven and at the same time it comprises the
external means for vertically positioning the
pan. It is of course obvious that these two func
tions are entirely distinct and independent,l and
therefore a modified form of the invention is
illustrated in Figs. 5 and 6 wherein separate
handles |00 and |0| are provided, the former be
ing mounted upon the shaft 52 (not shown) and
adapted to be rotated to vertically po'sition the
pan, and the latter being fixed to the front face
of the stove and used for moving the drawer
15 laterally. The handle |00 is relatively small
and the operator therefore will normally not
attempt to withdraw the drawer by grasping this
handle but will pull the drawer out by means of
the larger handle |0|.
Another modified construction has also been
illustrated in Figs. 7 and 8 wherein a dial |04
is mounted upon shaft 52 (not shown), while the
larger handle |05 serves to move the drawer later
ally of the oven. The two handles are positioned
relatively close together as shown so that when it
is desired to move the dial |04 to adjust the pan
vertically, the handle |05 may be used as a con-U
venient rest for the hand so as to make it easier
to turn the dial with one or two ñngers. Suitable
30 indicating means such as a pointer |06 may be
provided on the dial to indicate the position of the
pan elevating mechanism. If desired, the face
of the drawer may be calibrated in terms of the
vertical position of the pan, and thus it is possible
CJ El to position the pan at any desired height, without
opening‘the drawer, by setting'the indicator on'
the dial to the desired point on the scale.
While the form of apparatus herein described
constitutes a preferred embodiment of the inven
40 tion, it is to be understood that the invention is
not limited to this precise form of apparatus, and
that changes may be made therein without de
parting from the scope ofthe invention which is
means establishing an operating .connection be
tween said handle and said arms, including links
pivoted to one of said arms and formed with a
projection adapted to overlap said intermeshing
gear faces in all positions of the latter.
