HINGE FOR. STOVE-DOORS.

VTo azzwhomamycomm;

Be it known that I, GUY B. CHILD, a citizen of the United States, residing at Chicago, in the county'of Cook and State of Illinois, have invented-certain new and usefful Improvements in Hinges. for Stove- Doors, of which the following is a specification, reference being had thereln to the accompanying drawing.

This invention relates to improvements in vhinges for stove doors, and is adapted particularly for use in a gas oven which operates on the tireless cooker principle.

In gasovens which operate upon the lireless cooker principle, it is necessary that the oven be tightly closed, and therefore necessary that the oven door be constructed to makea tight joint .at its edges with the outer wall of the oven.

' The object of the present invention is to provide a yielding pivot or hinge for the door, whereby a tight closure can always be made between Ehe inner edge of the door and thev outer wall ofthe oven, the door being pressure held.

`A further object of my present invention listo combine with the yielding pivot-or hinge a packing between the door and the shown outer wallof the oven, whereby the packing and its engagingmetal wall will be yieldingly and pressureheld, thereby making va tight joint between the door and oven wall, the packing preferably carried by the door.

Figure lis a perspective view of an Oven door and-hinge embodying my invention, shown in relation with la portion of the oven wall, and one edge of the door shown partly in section.

Fig. 2 is a side elevatin ofthespring or yielding hinge.

Fig. 3 is a top view of the door, with the hinge partly in` horizontal section, the door being' shown asit begins to engage the wall of the oven.

Fig. 4 is a view similar to Fig. 3, the parts in their positions when the door is closed. e

Referring now` to the drawings, 1 is a portion of the outer wall of a gas Oven and 2 its door. The door is provided at one edge with the usual hinged lugs 3. 4Secured to the oven wall is a suitable combined spring and pivotal rod housing 4, which has an outer vertical -wall 5, the end walls 6, and

rod 8 near its ends.

our screwed to the outerIface ofthe oven. A

A leaf-spring 10 .is vertically arranged i within the housing'4, the spring having its center normally bowed outward and resting,

on the outer wall 5 of the housing 4, while the ends 11 of the spring engage the pivotal Theopenings in the end walls 6 of the housing 4 are elongated outwardly sothat the pivotalrod isvadapted to have an inand out movement in the housing 4. The vspring 10 normally holds the pivotal rod '8 in its' inward position, shown in Fig. 3, and when the door is closed, the pivotal rod isv forced outward against .the tension -of the spring 10 into the position shown in Fig. 4.

The edge ofthe oven door 2 is provided with a'suitable packing 12, and this packing is preferably made ofthe form of an asbestos strip or cord and will be held to' the door in -any suitable manner.

This spring hinge arrangementv provides for a yielding action and holds the packing under a spring pressure and also insures an even engagement of the edge of the door all the way around, thus making an eifective tight joint to prevent the escape of the air that is in the oven when it is closed and operating, on the tireless cooker principle.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent is:

1. In a door hinge, the combination with a vdoor frame, of -a door, a laterally movable hinged connection between one edge of the door and the frame, ayielding means holding the hinged connection normally inward, and means forming a closing connec- Athe door and the outer wall, said hinge connection comprising a vertieal housing secured to one ofthe said members, the other member having-hinged ears, a pintle between the ears and the housing having a lateral movement, a spring normally holding the pintle in its inward position.

3. The combination with a frame, of door therefor, a hinge between one edge o? the door and the outer wall of the frame, said hinge comprising a vertically arranged housing secured to one of said members, the other member having hinged ears, a pintle rod passing verticallythrough the ears and the said housing, the pintle openings of the housing being elongated outwardly, a spring for normally holding the pintle rod inward.

4. The combination with a frame', of a door hinged thereto, the hinge comprising a vertical housing secured to the wall of the frame, the housing having inner and outer and end Walls, the door having hinged ears, the end walls of the housing havin outwardly elongated openings, a pint e rod passing through the hingedL ears and through the elongated openings of the housing, voutwardly bowed leaf-spring located between the pintle rod and the outer wall of the housing.

5. The combination with a door frame of a door, an elongated hinge connection bedoor hingedl thereto at one' edge, the said i hinged connection laterally movable with respect to the door frame, yieldable means for normally holding` the said connection in its inward position, the said yieldable means engaging the hinged connection at a plurality of points.

7. The combination with a frame, of a door hinged thereto at one edge the said hinged connection laterally movable in rcspect to the door frame, vieldable means centrally supported and having its ends engaging the hinged connection for normally holding the said connection in its inward position.

.In testimony whereof I hereunto aiflx my signature in the presence of two witnesses.v
