STOVE-DOOR FITTING.

Specification of Letters Patent.

Application filed'February 24, 1920. Serial No. 361,037.

To all whom it may concern: I

Be it known that I, THOMAS J. MCWIL- LIAMS, a citizen of the United States, residing at 1519 Clark avenue, in the cit of Cleveland, county of-Cuyahoga, and tate of Ohio, have invented a new and useful Improvement in Stove-Door Fittings, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish itfrom other inventions.

My invention pertains to a stove door fitting and more particularly to the manner of connecting a stove door about its hinge.

The objects of my invention, besides designing a construction of this character which will be of simple, durable and sightly construction, are

1. To conceal a lug required to support a downwardly swinging door when it is in its lowermost or substantially horizontal position. Instead of having such lug, which is commonly used for this purpose, positioned in front and externally, I reverse the construction by providing the lug internally and behind the plane of the door opening. Instead of the door swinging down to rest upon'the lug or lugs a projection from the bottom of the door swings upwardly against the underside of a lug or lugs. v

2. To provide flush bordering surfaces for the sill of a peculiar door in. a door construction shown described and claimed in the co-pending H. J. Trenkamp application for Stove oven entry filed May 9, 1919, Serial No. 295,885. According to the disclosure of such prior application a large door was hung to swing downwardly and such large door carried two complementary doors hinged to swing in opposite directions sidewise. My present invention enables dishes to he slid out of the oven compartment without encountering a ridge where the edge of the doorconforms to the edge of the oven compartment; and this facility obtains regardless of which door is open.

Adverting to the drawings Figure I is a front elevation of a stove embodying my invention, showing all doors closed.

Fig. II is a horizontal section on line II--II of Fig. I looking downwardly. Fig. III is a. vertical section on line III--III of Fig. I. looking to the left, and with the main door open. i

Fig. IV is an enlarged vertical section on line IV--IV of Fig. I looking toward a hinge showing the relation of the parts when the door is closed.

Fig. V is a section corresponding to that of Fig. IV showing the relation of the parts when the door is opened.

Fig. VI is an enlarged fragmentary front elevation with certain portions indicated in dotted lines. a

Fig. VII is a section on line VII-VII of Fig. VI.

Fig. VIII is a similarly enlarged horizontal section on line VIII-VIII of Fig. I.

The stove casing is supported on four legs 1 and comprises a bottom 2, a front frame 3, side walls 4, a rear. wall 5 having an open Patented, Oct. 25, 1921.

ing above in communication with a stack 6 and a top 7. Supported in any suitable manner within the stove casing so as to be spaced from the side walls 4 and the rear wall 5 is an oven compartment comprising a bottom 8, rear wall 9 and side walls 10. Inasmuch as the manner of so supporting an oven is old in the art and forms no part of this invention its detailed description has been dispensed with. In consequence however, of such spaced relation of the oven compartment, an enveloping flue space 11 is provided. Carried by the inner surface of the rear wall 5 are brackets 12 supporting each one end of burners 13 which have their opposite ends 14 supported in the front wall 3. The manner of igniting the burners 13 is of no interest to this application. Sufiice it to say that each burner 13 is located underneath the middle of one lateral half of the oven compartment. The burners 13 are both supplied with fuel from a gas sup ly pipe 15, from which the flow is control ed by valves 16.

It is to be understood that the entire space available within the stove for the purposes of an oven is open at the front side but may be divided in half by means of a removable artition 17 shown in Figs. II and III. large 'door will afford access to the entire oven space while two smaller doors will afford access to the divisions of the oven on opposite sides-of the partition 17 when the latter is in place.

As will be observed in Fig. VIII the edge 18 nions 21, being thus adapted to swing downw-ardly toward a horizontal position. Means is provided for limiting such downward swinging movement and the arrangement is additionally such that when the horizontal position is reached no part; of the door will project higher than the level of the bottom 8. Secured to the trunnions 21 are a pair of levers 22 and connected with the free ends of the latter are a pair of tension springs 23. The opposite ends of these springs are attached to the frame of the stove in a manto resist the downward swing of the door 19 and-to ease its return or closing action. The

two extreme positions of the lever 22 and spring 23are shown in Figs. V and VII respectively. The front frame of the stove is provided on opposite sides with a pair of forwardly curved caps 24 adapted to inclose the trunnions 21 and conceal the levers 22. Depending from the two lower corners of the door 19 are a pair of lugs 25 adapted to swing upwardly to the rear in suitable recesses 26 as shown in Figs. I- and IV to VII inclusive, so as eventually [to engage abutments or stop surfaces 27 as shown in Fig. V. When such engagement occurs the main door 19 will be in a substantially horizontal position, according to one feature of my invention. The inside surface 28 of that portion of the door frame which extends between the trunnions 21 will be precisely level with the upper surface of the bottom 8 of the oven compartment as appears in Fig. III and still more clearly in Fig. V.

- This makes it very much easier to withdraw any baking receptacle and enables the same .to he slid smoothly owing to the absence of any obstructing edges.

As may be seen in Fig. VIII the innermost upright edge 29 of the main door frame 19 is adapted to abut the recessed edge 18 when the main door is closed thereby afi'ordingan effectual heat seal. 1

Hinged at 30 and 31 on two opposite sides of the main door are a pair of smaller doors 32 and 33 provided with handles 34 and 25- respectively. ,These doors are adapted to swing laterally in opposite directions when the main door is closed. Inspection again of Fig. VIII discloses that when the door 32 is closed against. the frame 19, it effects engagement therewith along an upwardly extending plane 36 thereby similarly forming a heat seal. I

For the same reason that the surface 28 is level with the bottom 8 when the main door is open, I. have so designed the conshown in Fig. V.

Clearl it is of equal advantage to be able to withd i'aw a baking dish without having its bottom encounter an obstruction when either of the smaller'doors 32 or 33 are open. I have, therefore, as appears in Fig. IV, also so fitted the parts that the upper "edge 38 the lower horizontal front line of the oven compartment will, when the main door is closed rest level with the bottom 8. In this manner, when either of the smaller doors is open,'a baking receptacle may be withdrawn smoothly or momentarily allowed to rest in a level position partly upon the bottom 8 and partly upon such bordering edge 38 preparatory to being regripped and either returned for further baking or lifted out of the oven. Since the upper edge 38 moves only when the large door opens, manifestly, it occupies the same position as shown in Fig. IV when the smaller door 32 is open. Therefore, if the door 32 is considered 'as having been swung 0 en and out of the way, it is clear that ha ing utensils may be smoothly slid from the bottom 8 over the surface 38 which remains level therewith.

1. A stove' door fitting comprising the combination with a stove having an oven compartment, of a door adapted to afford access to one entire side of said comparts ment and to have its inside wall rest level with the bottom of said compartment, another door carried by said first mentioned door and adapted to afford direct access to only a part of said compartment, a stationary part of said larger door resting level with the bottom of said oven compartment to form a continuous smooth surface when said smaller door is opened.

2. A stove door fittingcomprising the combination with a stove having an oven compartment, provided with a sill, of a horizontally hinged door adapted to afi'ordaccess to one entire side of said compartment and to have its inside wall rest level with said sill, another door vertically hinged to of the main door frame 19 which borders 2 comprising a support provided with a substantially horizontal surface, and a member movably attached to said support, said member being fashioned with two surfaces angularly disposed with reference to each other, each of said member surfaces being adapted to assume a position level with said support surface depending upon the position of said member relative to said support.

5. A stove door fitting comprising the combination with a stove having an oven compartment including a bottom, of a door for said oven and movably carried by said stove, said door being adapted to assume two different positions of rest and fashioned with surfaces adjacent to a defining edge of said oven compartment and adapted each to come level withsaid bottom when said door is in one of its positions of rest.

6. A stove door fitting comprising the combination with a stove having an oven compartment including a bottom, of a main door for said oven and hinged to said stove, a smaller door hinged to said main door, the latter being fashioned with edges bordering an edge of said oven compartment and each adapted to assume a position substantially level with said oven bottom when the main door is open and closed respectively, whereby baking utensils may be smoothly slid from said oven regardless of which door is opened.

7. A stove door fitting comprising the combination with an oven bottom, of a door provided with distinct edges adapted to lie level with said bottom when said door is open and closed respectively.

8. A stove door fitting comprising the of doors to said oven carried one by the other, said carrying door provided with distinct edge surfaces disposed in angularly related planes, one of said edges being level with said oven bottom when such carrying door is open, and the other edge surface being level with saidoven bottom when such carrying door is closed for the purpose specified.

9. A stove door fitting comprising in combination, a compartment provided with an abutment, a spring attached to said compartment and a door provided with two lugs, one lug adapted to engage said abutment and the other lug to be restrained bysaid spring respectively.
