4clalms. (cl. 12s- 194) This invention relates -to the oven doors of soldered 0r Spot welded to the inner side of stoves and ranges and means for hlnging said the Wall |6-v doors te the lower edge of the oven opening, and Mounted in the side edges oi the door between among the objects of the invention are; to prothe Walls I6 and I7 are a Delref bex-like hinge vde a hinge construction wherein practically leaves 22 that constitute the movable leaves 0f 5 all of the hinge elements are concealed, to prothe Oven dOOr hinge Structure. Mounted in and vide a hinge construction which will permit the extending between the side Walls 0f said hinge door to be readily applied to and removed from leaves (See Fig. 4) are hinge pintles 23, Which the stove body by the mere manipulation 0f a, are adapted to enter and seat in the slots Il of i0 pair of hinge pintle latches and without requirthe bracket I3. The pintles 23 are removably 10 ing the removal of the pintle or any other hinge locked in the $10158 I4 by latches 24 pivOted at 25 elements, to provide a, hinge construction that on the brackets I3 and having on their forward will avoid any chang or marring of the enamel ends Curved depending fingers 26 that hOOk over of the stove front in the region of the hinge, te the pintles 2.3, as Clearly ShOWn in Fig. 4- The provide an improved spring-actuated device for inner wall I'I of the door has slots 21 and the 1li supporting the door in fully lowered 0r open p0.. top walls of the hinge leaves 22 have slots 23 siton and assisting the closing movement, and to registering With the Slots 27 that permit the provide a hinge construction especially weil brackets and latches to enter the lower` edge poradapted for use on double-walled insulated doors. tlOn 0f ille dOOr and engage With the Dintles 23. An illustrative embodiment of the invention is The Channel frame members, such as l0 and 20 shown in the accompanying drawing, in which- II, are usually of porcelain, and the brackets Fig, 1 is a, perspective view 0f a lower coi-ner I3 and latches 24 project from the bar l2 through portion of the oven opening and door, showing vertical slots 29 (Fig. 1) in the horizontal frame the latter in fully lowered or open position.

Describing this mechanism, 30 deszontal member and II one of the vertical side ignates a pin mounted in and extending between members of an oven door frame, these frame the side walls of each hinge leaf 22 in rear of members being preferably of the inwardly facing the hinge pintle 23. 3| designates a at link, 40 channel form indicated in the drawing. Secured preferably of the form shown in Fig. 1, that is in and forming in effect a. part of the frame memslidable through a vertical guide slot 32 in the ber IIJ is a bar I2 having on its ends forwardly lower end of the side frame member I I along the projecting brackets I3 formed with horizontal side wall of the oven.

An important advantage of the described strucapplication and removal of the door. To apply the door it is necessary only to raise the latches 24, enter the hinge pintles 23 in the bracket slots I4, 'lower the latches, and then pull forward the links 3| and engage their hooks 33 with the pins it is necessary only to disengage the hooks 33 from the pins 30, raise the latches 2|, and then withdraw the door from the stove body.

Variations and modifications in the details oi structure and arrangement may be made withi the scope and coverage of the claims.

I claim:

1. In a stove, door frame and a door having spaced outer and inner walls, of means for removably hinging said door at its lower edge to the lowerV horizontal member of the frame comprising forwardlyI pro- 'jecting brackets on said lower frame member having slots open at their forward ends, box-'like hinge leaves mounted in the side edges oi said door between said walls; hinge pntles mounted 1n and extending between the side walls oi said leaves and adapted to enter and seat in said slots, and latches pivotally connected to saidlower frame member adapted to engage with. said pntles and lock the latter in said slots; said door and hinge leaves having suitably located slots to permit said brackets and latches to engage with said pntles.

2. In a stove, the combination with an oven door frame and a door having spaced outer and inner walls, of means for removably hinging said door at its lower edge to the lower horizontal 30. To 'emove the door,

the combination with an oven member of the irame comprising forwardly projecting brackets on said lower frame member having slots open at their forward ends, box-like hinge leaves mounted in the side edges of said door between said walls, hinge pntles mounted in and extending between the side walls of said leaves and adapted to enter and seat in said slots, and latches pivotally connected to sa'id lower frame member adapted to engage with said pintles and lock the latter in said slots; the inner and lower edge walls of said door and the top walls of said hinge leaves having suitably located slots to permit the entrance of said brackets and latches into engagement with said pntles.

3. In combination with the subject-matter defined in claim 1, pins mounted in and between the side walls of the hinge leaves in rear of the hinge pintles, links mounted to slide inwardly andoutwardly along the side walls of the oven and having on their forward end hooks removably engaged with said pins, and springs exerting an inward pull on said links; said door and hinge leaves having suitably located slots to permit said hooks to be engaged with and disengaged from said pins.

4. In combination with the subject-matter dened in claim 1; pins mounted in and between the side walls of the hinge leaves in rear of the hinge pintles, links mounted to slide inwardly and outwardly along the side walls of the oven and having on their forward ends depending hooks removably engaged with said pins, pull springs anchored to the side walls of the oven and exerting an inward pull on said links, and stops on said links serving through contact with the door frame to limit the down swing of the door to a substantially horizontal position; said door and hinge leaves having suitably located slots to permit said hooks to be engaged with and disengaged from said pins.
