OVEN DOOR AN D HINGE THEREFOR.

Application filed September 14, 1923. Serial No. 662,858.

This invention relates to improvements in oven doors and hinges therefor comprising more specifically an oven door made of two ieces of sheet -metal composing an outer oor panel and inner lining, the door being provided with an improved form of friction hinge and stop. g

The object of my invention is to provide an oven door having a hinge, the working parts of which are carried jointly by the oven door' liningv and the door frame. 7 1

Another object of my invention is to provide an improved oven door and hinge which is so constructed that none of the working 1 parts of the hinge are carried by the outer oven door panel which enables the door to be made of light sheet metal and which further makes it possible to enamel the outer door panel without the necessity of wiping 29 or cleaning the enamel from the panel at those points where heretofore the working parts of the hinge have been attached to this panel.

Another and further object of my invention is to provide an oven door and hinge of an improved construction whereby the outer door panel can be enameled and the construction is such that the danger of the enamel breaking is practically eliminated. 80 A still further object of my invention is to provide an oven door and hinge of the type described wherein there is provided. a novel form of door stop. Another and further object of my invention is to provide an oven door hin e of a construction whereby the oven door is automatically held at any angle between its open and shut positions. I

Other and further objects, improved construction and novel features and results of my invention will appear in the following description and accompanying drawings.

In the drawings: Figure 1 is a front elevation of my improved oven door and hinge construction, the outer oven door panel being broken away at one corner to show thehinge lug or pintle construction. a

Figure 2 is a horizontal transverse sectional view taken on the line 22 of Figure 1 looking ;in the direction indicated by the arrows. t.

Figure 3 is a vertical sectional view taken ing theenameled door. panel.

on a line 3-3 of Figure 1 looking in the direction indicated by arrow.

Figure 4 is an end view in full line taken near line 33 of Figure 1, the oven door being shown in its open position.

Figure 5 is a fragmentary detailed .perspective view of the hinge, the hinge-parts being shown in separated, extended relation prior to the assembling of the hinge.

The oven door and hinge construction which will be hereinafter described is in a sense an outgrowth or improvement upon the hinge construction shown in Patent 1,067,- 676 of July 1, 1913, to M. A. Possons, which patent is assigned to the American Stove Company to which company the present application is likewise assi ed.

By the use of the construction of m improved oven door and hinge it is possi 1e to construct an oven door which comprises'two pieces of sheet metal which compose the outer door panel and the inner lining therefor. This materially cheapens and simplifies the manufacture of the door as it has been previously constructed.

My improved invention likewise cheapens and simplifies the enameling of the outer door panel for the reason that those hinge parts which arecarried by the door are carried by the inner door lining and, therefore, the necessity of wiping or removing the enamel from the outer door anel at those points where heretofore wor 'ng parts of the door hinge have been attached, is eliminated. The life of the enamel is likewise greatly lengthened and the chances or danger of the enamel breaking or cracking is greatly reduced by the reason that none of the hinge parts are carried by the enameled panel.

The door stop which is carried by the door lining also aids materially in protect- None of the advantages pointed out in the above are incorporated in the Possons patent referred to, or in any other construction known to the applicant or the applicants employer, the American Stove Company.

A detailed description of the several parts of my invention will now be given and other advantages will appear from this description.

c Referring to the several figures of the drawings in which like parts are designated a by similar reference numerals throughout the description, 6 designates an oven front and this oven front may, as appears in Figure '1, comprise the front of more than one oven. It is common in the art to provide an oven'having two doors, one door being for the baking operation of the oven and the other for the oven broiler.

The oven door comprises an outer panel 7 having inwardly bent or extending edges 8 and a rear panel 9 with inwardly bent or extending edges 10. The oven door front panel 7 and inner lining 9'are adapted to telescope in the manner clearly shown in Fi re 2 of the drawings, the inner lining fitting within the front or outer panel. The

- two parts of the door are held together at their bottom by two suitable bolts 11 in sep- Y aratedrelation. The oven door lining is provided with openings 12 adjacent to bolts so that they can be reached for insertion. or removal. The bolts 11 may be removed by a screw driver applied to th'ehead of .the

bolt exterior to the face of the said section. The removal of the bolts enables the outer face of the door to be also removed. The two door parts are held attheir top by the outwardly projecting door catch 13 which is in'construction a cylindrical sliding bolt which is spring sup orted within a suitable housing 14 carried y the inner door panel adjacent its top edge. The door catch 13 extends through both of the inturned top edges 8 and 10 of the oven door front panel and inner lining and in addition to fastening the two parts of the door together at this point it engages a suitable opening, in I the lug 15 which is carried by the oven front 6.

- door panel a Adjacent the top of the outer door panel there is suitably fastened by means of bolts 16, a door handle 17. To assure that the outer door panel is not bent inwardly out of shape when the handle is'fastened in place by the bolts 16 the inner door lining is provided with two outstanding projections 18 adapted to engagethe inner side of the outer jacent the openings through which the handle bolts 16 passand support the-door panel at these points.

Opportunity is taken at this time to direct attention to the fact that a very simple and cheap construction of door is provided in the manner just described. The outer door' panel is referably, provided with a central outwardly bulged portion 19 for the purpose of appearance and upon this bulged portion the trade name of the stove is usual- 1y applied. It is, of course, understood that outwardly extending hinge pintle 21, which pintle carries'upon its end a cam 22. To allow for the passage of the downwardly ex-. tending portion of the pintle it is necessary that the telescoping walls 8 and 10 of the oven door front and lining be cut out as at 23. The L-shaped brackets 21 carry at their lowermost corners outwardly extending projections 24 which extend through the oven front panel to form a stop for the door, and operate in a manner which be described.

Carried upon the ovenfront 6 at its opposite edges adjacent the door are the L- shaped hinge spring members 25. These parts are fastened adjacent their top by suitable bolts 26 or the like and carry between them and the oven front 6 wearing plates 27. The lower ends of the spring members 25 are bulged outwardly as at 28 which thereby, provides an opening or housing. The horizontal legs 29 of. the L-shapcd spring members 25 support the hinge pintle 21 While the cam 22 of the hinge pintle is adapted to pass through the opening 30 into the housing back of the bulged portion 28 of the spring members. The cam ends 22 of the pintles engage the bulged portion 28 of the spring members and as the door is opened and the hinge pintle rotated these cams exert an outward pressure upon the spring members. When the door has reached its open position the ends of the stops 24 will engage the top of the horizontal leg portion 29 of the spring members. The wearing parts 27 will, of course, protect the front 6 against the action of the cams 22 and these parts 27 are preferably made of hardened metal to resist wearing.

The operation of the door is obvious.

will hereinafter When the-door is closed the hinge parts are ends the lower ends of these members can be sprung outwardly to the position shown in Figure 4. As there is constant tension upon ill! the cams 22 of the hinge pintles the oven.

door will stay in practicallyany position at which it is set.

. -Due to the manner in which the hinge pintles are mounted uponthe inner oven door lining there are practically no openings in the outer door panel around which the wiping of the enamel must necessarily take place. The oven door outer panel has only four openings, two of them being for the assa e of the bolts which hold the door and e and the other two being for the passage of the .oven door stops 24. Because of this construction there ,is practically no strain put upon the outer door panel and this eliminates to a high degree the danger of cracking the enamel on the panel.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
