.OVEN-DOOR FOR STOVES.

SPECIFICATION forming part of Letters Patent No.392fl85, dated November 6, 11.888.

Application filed December 5, 1887. Serial No. 257.035. (No model.)

To all whom it may concern.-

Be it known that LWILLARD J. ANnRnws, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Oven- Doors for Stoves, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and use the same,

IO reference beinghad to the accompanying draw- 1ngs.

This invention relates to doors of that class having their hinges at their lower edges and their latches at the topsuch, for instance, as

r 5 those ordinarily used as oven-doors in stovesand in which it is desirable that the door when open shall stand in a horizontal plane beneath and opposite the opening disclosed, for the purpose of resting the dish or pan withdrawn from the oven thereupon.

The objects of the invention are to construct a door capable of being opened slightly and locked in such. position, having hinges integral with its body and provided with a supporting-arm beneath, which firmly and securely supports it when open, the whole to be simple in construction,economical in manuiactnre, and effective in operation.

To this end my device consists in the con- 0 struetion hereinafter described, which I consider the best means of carrying out my in vention.

In the drawings, Figure 1. is an elevation of a stove-door embodying my improvements.

3 5 Fig. 2 is a central vertical section thereof, the door being shown open. Fig. 3 isa detail view of a portion of one pf the supporting-arms and its hinge-bearing. Fig. i is a section of the hingeconnection of the arm to the stove o proper. Fig. 5 is a detail perspective on an enlarged scale of one of the supporting-arms and its hinge.

Similar letters of reference designate similar parts in the several figures.

i 5 A designates the door proper, having a handle, a, and provided with a catch, 1), at its upper edge adapted to engage a notched projcction, l3, affixed to and projecting from the door-frame at the proper point. The upper face of the projection 13 is struck on a curve approximately an arc of a circle, of which the hinges of the door are at the centenand is provided with several notches, as shown, in any one of which the catch Z) may be rested, thus locking the door either completely closed or 5 slightly open, as desired.-

At its lower edge the door is provided with two hinges--one on each corner. As they are of precisely the same construction, I will de scribe but one. The door-frame O hasa projection or car, c,preferabl y having rounded upper and outer face and flat lower face. Over and around this car is located a strap, D, removably secured in position by screws d pass ing into the door-frame above and below the car. Vithin the aperture thus left isloosely fitted a stud, A, preferably cast integral with and projecting laterally from the lower corner of the door A. On and about these studs the door turns as upon hinges, and when the catch 7) is in engagement with one of the notches of the projection B the weight of the door is lifted from said studs and it hangs from the catch 2), thus assuring the locking of the latter within the notch it engages. Moreover,when 7 5 the door is open and supported in a horizontal position by the "arm hereinafter described its weight rests on said arm as a fulcrum, and it is held rigidly in position by means of the studs A bearing upwardly against the ears 0.

At some distance below the lower corner of the door are pivoted two arms, E. As they are of precisely the same construction, I will describe but one. At its lower end the arm E is reduced, forming shoulders c, and having between them a lug, 0, provided with pintles e, extending laterally from each side thereof, all said parts being cast integral. Over these pintles is located a plate, F, constituting the other half of the hinge, said plate being re- 0 movably secured in place by screws f passing through it and into the body of the stove in this instance. Said plate is provided with a central aperture in its upper edge for receiving the lug c, and is recessed in its rear face on either side of said aperture for receiving the pintles 0. Moreover, the shoulders c of the arm E bear upon the exterior rounded face of said plate over and above the recesses in its rear face within which the pintles rest, :00 whereby an extremely strong and durable hinge is formed entirely of cast metal in but two pieces and capable of being taken apart instantly by simply removing one screw.

The body of the arm E is bent outwardly at E for permitting it to rest flat over the lower edge of the door when the latter is closed, and at its upper end is provided with two inward- ]y-projecting lugs or cars, G G, the former of' which is simply straight and slides normally along and against the edge of the door A. The latter lug, G, however, is provided at its end which is nearest the door with a pin, projecting therefrom at right angles and toward the other lug,G. The door A is provided along its outer face at each vertical edge with a raised portion or band, A, against which the upper inner corner of the arm E between the ears G G slides, and said band has a groove, A along its inner edge, within which said pin 9 fits. Upon the band A, at a suitable point, is also cast a stud, A". With this a construction, when the door is unlatohed at its upper edge and turned down on its hinges, the ears G G slide along the edges of the band A, the pin 9 within the groove A, until the upper end of the arm E strikes the stud A, which is properly placed, and by which the door is thus supported rigidly and firmly in a horizontal position. When the door is again raised to be closed, the ears slide back to the starting-point, and the arm' E assumes its normal position flat against the face of the stove and out of the way. To detach the arm, all that is necessary is to remove the screwf, thus loosening its pivot, twist its body until the ear G is raised above the band A and then carry it inward toward the center of the door until the pin 1 is disengaged from the slot A. In this manner the arms E may be removed if it is preferred to use the door without them, replaced, if desired, or substituted by new ones in case they become broken.

Having now described the objects, uses, and advantages of myinvention, What I believe to be new, and desire to secure by Letters Patcut, and What I therefore claim, is-

1. The combination, with a door having a laterally-projecting stud at its lower corner and an arm hinged at one end below said'door to the frame, its other end being adapted to rest beneath said door when open and support it in a horizontal position, of an ear on the door-frame, beneath which said stud rests, a strap having a recess fitting loosely over said stud and ear, and means for removably securing said strap to the door-frame, substantially as described.

2. The combination, with a door hinged-at its lower edge and provided along its vertical edges on its outer face with a raised band, said band having a groove along its inner edge, of an arm hinged below said door and provided at its upper end with a lug adapted to slide along the outer edge of said band when the door is opened, and also with another lug havingalaterally-projecting pin entering said groove in the band, as and for the purposes set forth.

In testimony whereof I afiiX my signature in the presence of two witnesses.

WILLARD J. ANDREWS.
