STOVE.

Application filed February 9, 1925.

It is common to hinge the doors of ovens so that they open downwardly, the door forn'ling a platform in front of the oven when open. It is desirable in such con- 5 structions to conceal the hinge so that with the door closed the hinge mechanism does not form an obstruction on the face of the stove. This is not only desirable as a matter of appearance but it is also desirable in a) that it permits of the more readycleaning of the stove surfaces. The present invention is directed to the improvement of the hinge structure of such a stove. ()ther features and details of the invention will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows aperspective view of a portion of a stove showing the method of assembling the door in an oven opening.

Fig. 2 an enlarged sectional View of the hinge on the line 22 in Fig. 4.

Fig. 3 a side elevation of the hinge from the door side of the frame.

Fig. 4 a perspective View, partly in section. showing the assembled door in open position. i

Fig. a front elevation'showing the door in closed position.

1 marks the door frame, ordinarily formed of a casting, having the door opening 2 and provided with jambs 3 ordinarily formed integrally with the door frame. Notches 4 extend through the jambs at their lower ends.

A door 5 is provided with pintles 6 at its lower ed e.

In assembling the door, the door is tilted to the position shown in Fig. 1, passed back into the oven, and carried forward throu h the notches 4 bringing the pintles 6 to tie rear of the frame 1 at each side of the notches 4. The pintles here are brought into a bearing 7 formed on the rear of the frame and secured in the hearing by a bearing plate 8 secured to the inner wall of the frame by scrcws'9.

At least one of the pintles 6 is provided with a. groove 10. A coil spring 11 is ar- Q ranged on the pintle and has one and 11 bent inwardly extendin into the groove 10. The opposite end 11 0 the spring extends up along the back of the door frame. The spring is placed under tension as the dogr Serial No. 7,845.

is drawn forward into place and balances the door or resists the opening movement of the door.

In order to limit the opening movement of the door a stop 5 is provided on the edge of the door, the door being preferably provided with a cast frame and this stop 5 engages the lower end of the jamb 3 at the top of the notch 4i and thus limits the opening movement. The length of the stop 5 may be such as to readily give the necessary levera e to support the door.

Ordinarily in place until the door is brought to place and the bearing plates secured. After this is done the side linings l2 areput in behind the fianges 13 and swung into position at the rear againzt the side walls 14 of the oven. The-rear plate 14 .is then moved into place having the flanges 15 which rest against the side walls and the back 16.

What I claim as new is 1. In a stove, the combination of integral door frame sides having jambs notched at their lower ends; and a door having pintles extending therefrom through the notches and extending back of the door frame at the sides'of the notches.

2. In a stove, the combination of an oven chamber; a door frame at the front of the chamber having jambs notched at their lower the oven sides are not putends; and a door having pintles extending therefrom back of the door frame at the sides of the notches, the chamber having diagonal dimensions greater than the length of the door to permit the assembling of the door and frame by passing the door diagonally into the chamber and drawing the door forwardthrough the notches.

3. In a stove, the combination of integral door frame sides having 1ambs notched at their lower ends; a door having pintles extendin therefrom through the notches and extending back of the doorframe at the sides of the notches; and a concealed spring resist ing the opening of the door.

4. In a stove,-the combination of integral door frame sides having jambs notched at their lower ends; a door having pintles extending therefrom through the notches and extending back of the door frame at the sides of the notches; and a concealed spring acting 3n the pintles resisting the opening of the 5. In a stove, the combination of integral door frame sides having jambs notched at their lower ends and inwardly extending pintle hearings; and a door having pintles extending therefrom through the notches and journaled in the pintle hearings in the frame.

6. In a stove, the combination of integral door f'ame sides having jambs notched at their lower ends; and a door having pintles extending therefrom through the notches and extending back of the door frame at the sides of the notches, said door having a stop acting on the door frame limiting the opening movement of the door.

7. In a stove, the combination of a door frame having jambs notched at their. lower ends; and a door having pintles efxtending therefron'i through the notches and extending back of the door frame at the sides of the notches. said door having a stop acting on the lower end of a jamb limiting the opening movement of the door.

8. In a stove, the combination of an ovenbearings, the chamber having dimensions relatively to the door to permit the assembling of the door in the frame by passing the door diagonally into the chamber and drawing it forward through the notches, said door having a stop action on the lower end of the jamb limiting the opening movement of the door; and a concealed spring resisting the opening movementof the door.

In testimony whereof I have hereunto setmy hand.
