ALBERT MEADOWS, OF,DETROIT, MICHIGAN, ASSIGNOR TO DETROIT VAPOR STOVE COMPANY, OF DETROIT, MICHIGAN, ACORPORATION OF MICHIGAN..

STOVE FIXTURE OR DOOR HANGER.

Application filed July 15,

To all whom it may concern Be it known that I, ALBERT MEADOWS, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Stove Fixtures or Door Hangers, of which the following is a specification.

This invention relates to stove door fixtures or hangers and has for its object a fiX- ture which will not only stiffen the door frame but which will form a suitable fulcrum on which the door arms may roll to give a hinging action. A. further object is to interpose a suitable spring resistance to the opening of the door to cushion the same when it descends.

Furthermore, a pair of these fixtures are so designed that they connect the upper and lower stove doors and form a unitary structure for not only reinforcing the stove front, but also to fulcrum the doors and cushion the doors in opening. These features will be better understood when the construction is described in detail.

In the drawings,-

Fig. 1 is a fragmentary front elevation of a gas or vapor stove showing the oven and broiler chamber doors.

Fig. 2 is an inside elevation of the doors showing the fixtures in place.

Fig. 3 is a section on the line 33 of Fig. 2.

Fig. dis a similar view showing the lower door open.

Fig. 5is a section on the line 55 of Fig. 1, with the .door open.

Fig. 6 is a detail in perspective of the fulcrum block.

Fig. 7 is a section on the line 77 of Fig.

Fig. 8 is a similar section showing the upper door open.

Fig. 9 is a perspective of the upright angle bar used in the fixture shown in Figures 7 and 8. v

Fig. 10 is a perspective of the upright angle iron used in the fixture shown in Fig ures 3 and 4:.

Referring to Fig. 1, it will be seen that 1922. Serial No. 575,345.

the oven is provided with a door a and a broiler chamber with a door I). These doors are ordinarily supported on trunnion-like projections which are held in trunnion sockets formed by plates bolted to the oven frame. This construction is unsightly and furthermore the trunnion socket plates often get loose and make the action of the door sloppy.

It is the object of the present invention to provide a more effective support for the door. The front frame 0, (Fig. 5) is prefer ably a pressed steel piece, and stove bolts d are run through the front of this at a point where the stove door wings 10 will cover-the bolt heads when the door is closed. These bolts hold in place the fulcrum blocks 6 and also the angle bar uprights f. This angle bar f extends along the side of the lower door opening up to and slightly beside the other door opening as is shown in Figs. 3 and 4. It, therefore, serves to reinforce and strengthen the stove front construction. It carries the load of both doors. Nuts h and 2' bolt the fulcrum blocks, the angle bars f, and and the front frame 0 together. Furthermore, there is clamped between the fulcrum blocks and angle bar f, the turned in edge y of the side wall of the oven.

The fulcrum block 6 is shown in perspective in Fig. 6 and comprisesablock provided with an opening 70 and a stationary fulcrum roll m. A locating pin 91. is an integral part of this block casting and is adapted to protrude through the angle bar f as shown in Figs. 3 and 4, to properly locate the fulcrum block with respect to the other members.

An integral part of the door frame 0 is the hinge arm 29, which is part of the same casting. This hinge arm is curved and is provided with a stop or shoulder 9 adapted to engage against the point r on the inside of the angle bar to hold the door from open ing down below a horizontal position. The fulcrum block and upright angle bar 7 serves as strain resisting means at this point to resist any strains brought upon the structure by the open door.

The upright angle bar f is provided ith too a spring abutment s riveted thereto. A coiled compression spring is coiled around the rod a. This rod to is provided with a shoulder or abutment o, the end of the rod runs through the bent end of the hinge arm a: and is pivotally connected thereto. .When the broiler chamber door is open this hinge arm a rolls on the fulcrum roll at and the compression spring t tends to resist the upward movement of the rod u and thereby cushions the broiler chamber door.

The angle strip 3/ used on the opposite side of the oven and broiler chamber (see Fig. 2) serves in precisely the same way to reinforce the oven front frame and to hold the fulcrum blocks, on which the hinge arms roll, however, no rod 14 is required, but simply a tractile spring a which connects the upper hinge arm 7; with the lug Z stamped out of the angle bar. This tends to cushion the descent of the upper door.

What I claim is:

1. In stove construction, the combination 'of walls forming a chamber having an opening thereinto, a door for closing said opening, an upright bar removably secured to said Walls, a fulcrum block supported by the upright bar and including a fulcrum roll, a hinge arm supporting the door and arranged to turn on the fulcrum roll and a spring secured to one end of the upright bar and at the other end secured to the hinge arm to cushion the opening movement of the door.

2. In stove construction, the combination of a frame including a pair of openings, a pair of doors for closing the openings, an upright bar secured to the back of said frame and reinforcing said frame, a pair of fulcrum members supported by the upright bar, hinge arms secured to the doors and turning on the fulcrum members.
