1 Claim.

This invention is a divisional application of my co-pending application Serial No. 658,421 filed February 24, 1933, issued in Patent 1,969,197, August '7, 1934 and relates to improvements in stove door hinges and is especially intended for use on gas ranges for the oven and broiler compartments.

The invention has for its general object the provision of a stove door hinge of sturdy, yet light construction which can be quickly and conveniently assembled and disassembled.

A further object of the invention is to provide a stove door hin e having slip hinge connection which permits of a door being readily disconnected from the front frame of a stove.

A still further object of the invention is to provide a stove door hinge having a slip hinge connection which when used on a stove door will permit of the door spring being readily disconnected without the necessity of dismantling the door.

The detailed construction of the invention will be more particularly explained in connection with the accompanying drawings, wherein a preferred embodiment of the invention is illustrated.

In the drawings:

Figure 1 is a fragmentary vertical sectional view through a gas range showing the drop doors thereof in open and closed position and also showing in dash dotted lines a door pulled away from the frame;

Figures 2 and 3 are enlarged perspective views of the stove door hinge when disassembled. Thus Figure 2 is a perspective view of the pivot pin, seated in an apertured lug of the frame and Figure 3 is a perspective view of one of the hinge brackets arranged in a lower corner of a door;

Figure 4 is a fragmentary horizontal sectional view through the front frame of the oven showing the slip hinge connection between the door and front frame;

Figure 5 is a perspective view of the outer plate of the door with the truss rod in proper stantially identical with the other, a description of the baking oven door 5 will suffice for both.

Door 5 comprises an outer or front pressed steel plate 1, the outer face of which is finished in enamel as usual, and an inner plate or lining 9 also of pressed steel construction. The outer plate I is formed on all four sides with a flange Hi, extending at right angles to the face of the plate, the outer edge of this flange is rolled inwardly and downwardly upon itself to present a smooth rolled edge portion II, which greatly stiffens the plate and eliminates sharp edges which heretofore have frequently caused injury to workmen in the assembly and enamelling departments. These rolled edges at the lower side of the front plate also cooperate with the slightly offset edge l2 of the lower side of the inner plate or lining 9 to facilitate assembly and to prevent separation of the two plates at this point. The top and two side portions of the plate- 9 are formed with slightly flexible right angularly extending flanges l5 which snugly engage the rolled edges II and rest against the inner face of the plate 1. The space between the two plates is filled with heat insulating material l3, such as rock wool.

Angular hinge brackets or blocks I 6, secured to the lower inner corner portions of the lining plate by screws ll seat snugly against the side flanges 28 on plate 1. Apertured ears l8 formed on the hinge brackets and extending through slots IS in plate 9 and through slots IS in the front frame of the stove are adapted to receive screws 29 to which the outer ends of the conventional counter balancing door springs 22 are secured, but if desirable the springs may behooked directly in the threaded openings 2|. These springs extend horizontally to the rear of the oven between the outer side wall of the stove and the side lining, where they are connected to ad- 4 justing screws 25 extending through the back wall 26 of the stove. Removal of the springs for repair or renewal can be conveniently effected without dismantling the door, by merely taking down the lining plate 2? for the back wall of the stove, and of course disconnecting the outerend of the springs from apertured ears l8. The latter operation can be accomplished without dismantling the door.

The upper sides or portions of the inner and outer plates are securely fastened together adjacent their corners, the areas most likely to warp, by means of a tie or truss rod 29 which extends longitudnally of the doors and engages with its ends beneath the rolled edges II on the side flanges ID. This bar rests upon the insulation I3 in spaced relation to the plates 1 and 9 and is secured to the inner plate 9 by headed screws 30 which pass loosely through openings 3| in the plate Q and threadedly engage aligned threaded openings 32 in the tie rod. As the rod 29 does not directly contact with the inner faces of the opposing plates, it follows that when the screws 36 are screwed home the rod will be r siliently drawn towards the lining plate into clamping engagement beneath the rolled edges H. The slight bending of the tie rod gives the latter a truss effect and also prevents the screws 30 from becoming loose. Insulation l3 spaces the bar a considerable distance from the inner face of plate 7 thus greatly facilitating proper alinement of the openings 3! and 32 preliminary to inserting screws 35. A handle member 33 is secured in place by means of a bolt, not shown, extending through perforations 35 and 36 in the upper intermediate portions or sides of the respective plates 1 and 8. Side flanges [5 on the plate 9 are cut away at their upper corners as at 3'! to permit clearance of bar 29.

Hinge brackets It are formed adjacent their lower corner edges with a central slot 38 for receiving apertured lugs 39 projecting forwardly from the front frame of the stove, and with side recesses or pockets 4% for pivotally seating pivot pins 4| extending loosely through the apertured lugs 39. When the door is closed the end walls 42 of the pockets will rest upon the pivot pins and pivotally support the door, and accidental displacement of the pins or disconnection of the door from the frame will be prevented by the side walls 43 of the pockets. noted that when the door is swung to open or horizontal position, the door can be pulled away from the frame thus causing the pivot pins to be withdrawn from the pockets. The door However it will be aoeasm springs 22, which resiliently maintain the slip hinge connection between the two parts of the hinge, of course must be disconnected before the door can be removed.

pockets and to permit of close fit between the door and front frame.

Broiler door 6 is of substantially the same construction as door 5 with the exception that hinge brackets I6 are formed with a long arm I 8' in lieu of the apertured ears [8. The slots IS" in the lining plates through which the arms l6 extend are also somewhat longer than the slots l9. Coil springs 22' connected at their upper ends to openings 20 in the arms l8 are connected at their lower ends to the front frame 2. Shoulders 44' on bracket arms l8 engage the upper ends of slots 19 and support the door when in open position.

Having thus described my invention, what I claim is:

An improved range door hinge, comprising a door frame, a door having a front panel and a slotted rear panel, hinge brackets between said panels secured to the inner face of said rear panel and having an arm extending through the slot in said rear panel, each of said brackets having an exposed portion form-ed with a central slot and side pockets, apertured lugs on said door frame engaging in said central slots, pins loosely mounted in said lugs and removably seated in said side pockets, and springs connected to said arms and to a fixed part of the stove.
