STOVE OR OVEN DOOR SUPPORT.

Specification of Letters Patent.

Application filed April 12.1906- Serial No. 311,329.

To all whom it may concern.-

Be it known that I, RICHARD A. OULTER, a 1 citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Stove or Oven Door Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Oven-doors for stoves and ranges dropping or opening downward in time causes the oven-door to break, chiefly because the weight and force of the dropping movement of the door is downward upon the supporting-lugs of the hinges and tends to and does break the door and causes the loosening of the hinge-fastenings, and to avoid this objection I have devised a shouldered support hinge, whereby the force of the thrust of the falling door upon its supports is inward against the stove or range, relieving thereby the door from being broken.

In the accompanying drawing, which illustrates my invention, Figure 1 is a front view of a stove or oven door to which my improvements are applied. Fig. 2 is a vertical section showing the position of the door when closed and the shouldered door-supports. Fig. 3 is a like section showing the door supported in open position upon its shouldered directed inwardly against the hinge abutment. Fig. 4 shows in front view the position of the shouldered supports when the door is open, as in Fig. 3, the pintle of the door being shown in dotted lines.

Above the pintle 1 of the hinge the doorframe 2 is cast with an outward projection 3, terminating in a shoulder 4 at right angles to the face of the frame, the shoulder of the pro jection at each side of the frame being in horizontal alinement and form each a solid abutment on the door-frame. The brackets 5, which form the bearings for the hingepintles, are secured to the stove-plate 6, preferably by nutted bolts 7, and each bracket has a solid outward projection 8, which terminates in an abutment 9, the face of which is vertical or parallel with the base of the hingebracket, so that it presents a vertical bearing-surface against which the shoulder of the door projection abuts when the door has been dropped or opened to a horizontal position, thereby causing the weight or pressure of the door to be in an inward direction toward the base of the hinge, as shown by the arrow, Fig. 3, and therefore preventing the breaking of the door and their bolt-fastenings of all danger of becoming loose or broken. In the open position of the door its abutment-bearings and the bearing-surfaces of the abutments of the hinges stand in vertical planes, so that the door while being supported upon the hinge-brackets is also supported against them with a pressure in the plane of the bolt-shanks as distinguished from a pressure at right angles tp such plane and downward upon the pint es. 1;

Looking at Fig. 3 it will be seen that the shoulder 4 on the door-frame is in contact with the vertical face of the shoulder 9 of the hinge-bracket and that when these two shoulders come in contact by the falling of the door the force of the thrust will be direct ed inward by reason of the relation of said shoulder to the pintle-hinge, which causes the shoulder 4 in describing a circle to deliver an impact blow against the shoulder 9, and, so far as I know and can find, I am the first to provide a means of preventing the breaking of the door-frame by directing such force horizontally inward, and thus prevent the force of the falling door from giving a vertical impact on the hinge-brackets. In effecting this function it is important to note that the abutting stop-surfaces are formed on the door-frame in a plane approximately tangential to an are directed from the pintles of the door, whereby the stopping action will operate in a direction radial to the axis of the pintles, and the door will operate as an agent in preventing its own breakage.

In illustration of this and looking at Figs. 2 and 3 the path of the falling shoulder 4 is seen as concentric with the axis of the pintlehinge of the door, as shown by the curved dotted arrows in said figures and the relation of such shoulder to the axis of the pintlehinge, and also the relation of the axis of the pintle-hinge to a level with the horizontal face of the door-supporting bracket, to cause the angular point of the said doorabutment to strike the vertical face of said bracket, and thereby cause the impact of such blow to be directed inward, as indicated by the horizontal arrows in said figures, thereby rehevlng the door of the damaglng effects of the blow of the falling door upon said bracket.

I claim- 1 A pintle-mounted drop-door for stoves and ovens having a pair of front projections each forming a shoulder at an angle to the face of the door, in combination with forwardly-extending brackets for the pint] es of the door, each bracket having a front impactsurface, the axis of the door-pintles being permanently in a plane above the plane of said impact-surface, whereby in the dropping of the door the impact of the fall will cause the shoulders on the door facing toward the pintles to strike the impact-surface of said brackets which face away from the pintles and thus direct the force of the impact inward and prevent the breaking of the door.

2. A pintle-mounted drop-door for stoves and ovens having abutting stop-surfaces on the door-frame in a plane approximately tangential to an are described from the pintles, in combination with shoulders forwardly extending from the pintles-brackets and having front impact-surfaces, whereby the stopping action will operate in a direction radial to the axis of the pintles, and the door will operate as an agent in preventing its own breakage.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

RICHARD A. CULTER.
