HINGE FOR STOVES AND RANGES.

Application filed December 14, 1920. Serial No. 430,662.

To all whom 1115' may concern Be it known that I, STANLEY W. PALMER, a citizen of the United States, residing at Beaver Dam, in the county of Dodge, State of Wisconsin, have invented certain new and useful Improvements in Hinges for Stoves and Ranges 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.

This invention relates to stoves, ranges, and the like, and has for its object the pro vision of an improved draft door construction for stoves and ranges.

Various arrangements and constructions have been employed for mounting a draft door in operative relation with the draft opening in a stove or range. In general, it has heretofore been customary, as far as I am aware, to position the mounting of the draft door on the outside of the stove or range, and in many instances box-like structures project outwardly from the draft opening. in order to provide an appropriate seat for the draft door when in its closed position. This external mounting of the draft door not only mars the appearance of the stove or range, but is objectionable on account of its tendency to accumulate dirt. The present invention contemplates a draft door mounting by which the draft door in its closed position is substantially vertical and in direct contact with the wall of the stove. In other words, the inner face of the draft door lies flush with'the outer face of the wall of the range having the draft opening. Moreover, the support or mounting of the draft door is positioned within the stove so that only the door itself is visible from the outside. The novel features of the invention which I believe to be patentable are definitely pointed out in the appended claims. These features, together with the construction of a stove or range embodying the same will be understood from the following description taken in conjunction with the ac companying drawing, in which Fig. 1 is a perspective view of a range having a draft door mounted in accordance with the invention;

Fig. 2 is a sectional mounting;

Fig. 3 is a back or rear view of the mounting; and

view of the draft door Specification of Letters Patent.

Patented July is, 1922.

Figure eis a detail of one of the bearing brackets, Figures 5 and 6 are sections taken on the section lines 5 and 6 of Figure 3.

The range shown in Fig. 1 of the drawing has a front wall 10 provided with a draft opening 11. A movable door 12 is opera tively arranged in front of the draft opening and by appropriate movement is adapted to adjust the draft through the opening. The door 12 has an operating handle 13 for effecting the desired movement of the door as will be well understood by those skilled in the art.

In accordance with the presentinvention, the draft door 12 has a pivotal mounting positioned on the inside of the wall 10. The construction of this mounting is such that the door 12 is normally biased by gravity to its closed position. I closed position, the door 12 is substantially vertical and its inner face lies in direct contact with the outer face of the walllO. By this arrangement, only the draft door itself is seen from the outside of the range, and the pivotal mounting of the door is entirely concealed behind the wall 10. I

The draft door 12 is slightly dished on its inner face, and is provided with two pairs of lugs 14. A bracket 15 is positioned be tween each pair of the lugs 14 and is secured to the door by a rivet 16, or other appropriate When occupying its attaching means. The lugs 1 1 and the rivet 16 thus serve to securely position and fasten the bracket 15 to the draft door.

A goose-neck extension 17 is attached to the upper end of each bracket 15. The extension 17 terminates in a cross bar 18 which serves as a bearing shaft in the pivotal mounting of the draft door. The bracket 15, extension 17 and cross bar 18 may be and preferably are integral and to this end may be formed as a unitary casting.

The cross arms 18 are operatively mounted in bearing blocks 19 and 20 projecting from a plate 21. The plate21 is secured to the inside face of the wall 10 by rivets 22, or other appropriate fastening means.

Figure 5 of the drawing is a sectional view on the section line 5 of Fig. 3, while Figure 6 is a sectional View on the section line 6 of Fig. 3. Figures 5 and 6 accordingly show the construction of the bearing blocks 19 and 20, respectively. It will be observed that the bearing block 19 is closed and provides an outer bearing surface 19 for the rod 18, while the bearing block 20 is open and has an inner bearing surface 20 for the rod 18. The bearing surfaces 19' and 20 provide a suitable bearing for the rod '18 in which the rod, while firmly secured, is permitted free movement in the bearing provided thereby. At the same time, the construction is such that the rod 18 may be conveniently assembled in its operative position in the bearing provided by the blocks 19 and 20.

The configuration of the goose-neck extension 17 and the weight distribution of the draft door 12 are such that the door is normally swung by the action of gravity into contact with the outer face of the wall 10, so as to provide a firm closure of the draft opening 11 by the draft door 12. The draft door thus lies substantialy liush with the front wall of the stove when in its closed position and no partof the mountin'got the door is visible on the outer face of the front wall. By this arrangement, the stove presents an attractive and pleasing external ap pearanceand the operative parts of the drait door mounting are positioned. within the range where the accumulation ofdirt not of particular importance. In principle, the draft door is supported by a bracket secured to its inner face and having an inwardly and upwardly projecting extension 17 terminating in a bearing shaft 18 operatively mounted in bearing blocks 19 and. 20 secured to the inner side of the wall. 10 above the draft opening. As a result of this construction and arrangement. the draft door normally occupies. due to the action of gravity, a substantially vertical position with its inner "Face in direct contact with the outer face of the wall 10 thereby closing the drai't opening.

I claim:

1. A range having a substantially vertical wall provided with an opening, a door tor the opening, and a hinge connection between the door and the wall such that the door is normally biased by its own weight to swing inwardly beyond the wall, whereby to cause the door to press closely against the wall about the opening when closed.

2. The combination in a range having a substantially vertical wall provided with an opening, of a pivotally mounted door normally biased by gravity to and beyond the vertical, whereby when the door is closed it will press closely against the wall about the opening, the pivotal mounting of said door being positioned on the inside of said wall.

3. The combination in a range having a substantially vertical wall provided with an opening, of a movable door positioned outside said wall and normally biased by gravity to and beyond the vertical, whereby when the door is closed it will press closely against the wall about the opening, and means mounted within said wall for supporting said door.

a. The combination in a range having a substantially vertical wall provided with an opening, of a door positioned outside said wall in operative relation with said opening, bearing members secured to the inner side of said wall. and a bracket secured to said door and having an extension project ing inwardly and upwardly into operative engagement with said bearing members whereby said door is biased by gravity to its closed position with respect to said open 5. The combination in a range having a substantially vertical wall provided with an opening, of a door positioned on the outside. ott said wall in operative relation with said opening, a pair of cooperating bearing blocks mounted on the inside of said wall above said opening, a bracket secured to the inner face 01" said door and having an extension projecting inwardly and upwardly and terminating in a bearing shaft operatively mounted in said blocks whereby said door is norm ally biased by gravity to occupy a substantially vertical position in direct contact with the outer surtace ot said wall thereby closing said opening.

6. A range having asubstantially vertical wall provided with a door opening, and. a door pivoted to the wall at the opposite side from the door and mounted to swing toward the wall, whereby the door is biased. by gravity to swing inwardly beyond the vertical plane and to be pressed closely against the wall about the opening when closed.

7. A range having a substantially vertical wall provided with a door opening. a door for closing the opening, and a pivotal connection between the door and the wall, said connection being at the top of the door, and ofiset inwardly from the plane of the door, whereby the door will be biased by gravity to swing inwardly beyond the vertical to cause the door to be pressed closely against the wall about the door opening when closed.

8. A range having a substantially vertical wall provided with an opening, a door for the opening, and a hinge connection between the top of the door and the wall such that the door is normally biased by its own weight to swing inwardly beyond the wall, whereby to cause the door to press closely against the wall about the opening when closed.

In testimony whereof I aflix my signature.

STANLEY W. PALMER.
