This invention relates to hinge mounting means for
doors, and will be described with particular reference to
an oven door on a range.
However, it is to be under
stood that the invention may be applied to other doors on
other articles.

Ul ther opening 8 therebelow which may be an opening for
a drawer or the like. In the opening 8 a suitable drawer
(not shown in detail) may be mounted and provided with
a front cover or panel 10 overlying the margin of the
opening 8. As shown, the oven opening 6 and drawer
opening 8 are spaced inwardly from a side wall 12 of
the range housing to provide a hollow chamber-like space

A hinging means comprising a llat strap of sheet metal
supporting the oven door in such a manner that the hinge 15 is formed to provide a shank portion 16 having its lower
assembly or subsequent thereto, to position the door,
when in its closed position, at the desired distance from
or in abutting contact with the front face of the range
housing. The novel hinge structure comprises a hinge
member having a relatively long shank portion pivotally
mounted to the range housing on the interior thereof and
having its other end formed to a general hook-shape and
projecting outwardly through the front face of the hous
ing. The free end of the hook-shaped member carries a
hinge pivot on which a second hinging member is pivotally
mounted, said second hinging member being attached to
the oven door to hingedly support the same. An adjust
ing screw extends from the front panel of the housing in
wardly to an intermediate point on the shank of the lirst
named hinge member whereby rotation of the screw
effects adjustment of the hinge axis toward or from the
front of the range housing. Means are provided for lock
ing the screw against inadvertent change of position. The
hinge means further includes a counterbalancing means
comprising an arcuate arm extending from the second
hinge member and into the housing for attachrnent to a
counterbalancing spring.
compartment by suitable pivoting means 18, shown herein
as a bolt and nut. The shank portion 16 extends upward
ly from the pivot 1S and terminates in a laterally directed
hook portion 2li. The hook portion 20 extends forwardly
and outwardly of the housing 2 through a slot 22 in the
front face or wall 4 of the range housing. The hook
portion 26 includes a downwardly extending end portion
24 carrying a hinging pivot pin 26 thereon. While the
hinge member comprising the shank 16 and hook portion
20 are shown as including an olîset bend 28 therein, the
same will be referred to hereinafter as being substantially
ilat.
Intermediate its ends the shank portion 16 is provided
with an opening 30 (see FIG. 3) in‘which a trunnion nut
32 is pivotally mounted. The trunnion nut 32 comprises
a barrel pontion extending through the opening 30 and a
thin head 34 bearing against one face of the shank
portion 16. The barrel portion of the nut 32 is provided
with a transverse threaded opening 36 therein through
which an adjusting screw 38 is threaded. ’I‘he axis of
rotation of the trunnion nut 32 is substantially parallel to
the pivotal axis on which the shank portion 16 is mounted,
at 18, whereas the axis of the threaded opening 36 is trans

Another object of the invention is to provide a hinge
means of the type set forth that is not only adjustable
but entirely concealed when the door is closed and sub
stantially concealed when the door is open.
Still another object of the invention is to provide a
hinge means of the type set forth including a counterbal
ancing arm as a part thereof.
A further object of the invention is to provide a hinge
means of the type set forth that can be adjustably posi
tioned as described and then positively locked in the de
sired position of adjustment.
A still further object of the invention is to provide an
adjustable hinge means of the type set forth wherein the
adjustment may be performed from outside the housing
by the manipulation of inconspicuous adjusting means.

is provided with a slotted head 42 bearing against the
outer or front face of the housing. A suitable lock washer
44 and lock nut 46 are mounted on the screw ‘38 adjacent
the inner face of the panel 4.
A second hinge member 4S is likewise formed of flat
strap sheet metal and includes a portion Si) (FIGS. l and
2.) pivotally mounted on the hing-ing pin 26 previously
50 described. The portion 5t) is provided with a flange 52
at one edge thereof for a purpose to be described.
The
hinge member 48 extends upwardly from the portion 50
and is offset laterally at S4, then upwardly to define a
further portion 56 from which an integral arcuate anni
