WTLLIAIVII THOMPSON, OF KALAMAZOO, MICHIGAN.

OVEN FOR GAS OR VAPOR BURNING STOVES.

Specification of Letters Patent.

Application filed September 8, 1908. Serial No. 451,996.

To all whom it may concern:

Be it known that I, WILLIAM THOMPSON, a citizen of the United States, residing in the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Ovens for Gas or Vapor Burning Stoves, of which the following is a specification.

This invention relates to improvements in gas or vapor burning stoves.

provide in a gas or vapor burning stove an improved oven which maybe subjected to the direct heat from the burners, or to the radiated heat only, as desired.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a detail perspective of a struc ture embodying the features or my inven tion, portions being broken away to better show the relation of the parts. Fig. 2 is a plan view of the oven bottom, a detail section of the oven being shown to illustrate the arrangement of and for the adjusting link. Fig. 3 is an enlarged detail vertical section, taken on a line corresponding to line 33 of Fig. 2. Fig. 4 is a vertical seccorresponding to line l4: of Fig. 2, through the oven. bottom. Fig. is an enlarged detail taken on a line corresponding to line 5-5 of Fig. 2, showing one of the pivots for one of the oven bottom doors. Fig. 6 is a detail vertical section, taken on a line corresponding to line 6-6 of Fig. K) Fig. 7 is-a detail plan corresponding to that of Fig. 2 showing a modified construction in which the bottom of the oven has corrugations therein to increase the area subjected to the burner flames. Fig. 8 is an enlarged detail section, taken on a line corresponding to line S-8 of Fig. 7. Fig. 9 is a vertical section through a further modification of the oven bottom, it being provided with projections on its under surlink in the slot; the doors "face to increase its heat radiating capacity.

Fig. 10 is an inverted detail modification shown in F i 1.

In the drawings, simi ar reference characters refer to similar parts throughout the several views, and the sectional VIQWSQI'G taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, my improved plan of the stove has an oven 1, below which is a burner The main object of this invention is to 5 chamber 2, in which the burners 3 are located, the burners being indicated by dotted lines in Fig. l. The bottom 4: of the oven is provided with openings 5, extending practically across the same, there belng two openings in the structure illustrated. These openings are provided with downwardly and inwardly projecting flanges 6 and 7 at their edges adapted to receive the downwardly projecting flanges 8 and 9 of the doors 10. The flanges 7 of the openings are preferably curved, and the flange 9 of the doors 10 are also curved to seat therein, so that the door will bear or swing in the flange, as illustrated. The doors are also provided with a pivot 11 at each end, the plvots bein in alineinent with the bearing flanges 9. Sec Figs. 5 and 6.) These pivots fest in suitable bearings 12 provided therefor in the oven bottom 4-. (See Figs. 5 and 6.) On the pivots at one end, I arrange arms 13, the arms being provided with suitable holes to receive the pivots, the pivots having ribs 14 at one side which engage suitable notches in the arms, thereby preventing the turning of the arms on the pivots. The pivots are also provided with projections 15 to hold the arms in place. These arms are located within the space between the inner and outer walls of the oven. (See Fig. 1.) The pivots 11 are also preferably provided with lugs 16,which engage the ends of the bearings 12, thereby preventing the longitudinal movement of the doors in their bearings. The arms 13 Patented Nov. 2, 1909.

are connected by a link 1?, and to the forward arm I connect a notched link 18 which is arranged through a slot 1.) in the oven wall, so that, by engaging the notches of the may be adjustably held open. The link 18 is provided with a suitable hand piece 20, as illustrated. Above the bottom I preferably arrange a false bot-- tom or shelf 21 on which the articles to be cooked may be placed. This shelf is preferplaced upon the shelf.

ably foraminated, as illustrated, and is adjustably stn portod by the shelf ledges 22-, so that it can be adjusted to and from the bottom of the oven, as desired, the bottom ledge being spaced snllieiently from the bot:- tom to permit the opening of the doors so that the heated products passing through the openings, are delivered to the receptacles However, it desired, the doors themselves may be used as rests or Supports; for re-ffepti'ui-les containing; the articles to be roolred or billitil. the. shel ves or false bottom bei g ren'ioved. By thus ar ranging the openii and doors in the bottom, the heat from the burners may be turned directly into the oven,-that is, with the doors open, the hot pass into the oven or the doors (on be closed and the heat transmitted to the oven by radiation through the bottom, and through the inner wall, the space between the wal s being; connected to the chamber to serve as a llue for the escapepf the products of combustion, so that they pass doors are cloud.

Tlie'niain or the oven door proper is not illustrated in the accompanying r'lrawing, as its arrangement will be readily nnderstood. By providing the o 'wnings :7 in the oven bottom with the flanges and 7, and the door 10 with the liangye 8 and 9, when closed, a praetieally tight joint is formed around the door. A. lnrther advantage of these flanges that the doo and the parts of the boiioni about the door openings are th reby so that they are not I made rigid. likely to warp or become distorted and thereby prevent the proper closing ol the doors. V

An oven made according to any invention can be very quickly heated and brought to a higher tenipz'zrature downimrdly and outwardly projecting lian cs 9.0 at its rear and side edges, and

upnardly and outwardly projrwtingr flanges at its tor 'ard edge lor UHVLIJHIHZLHll] support ing'the same.

in the uccoinpanyiredrawing, l have illustrated and described my improvements in this application in d tail in the form preferred by me on ac ount. of structural sirn around the oven when 'the l plicity and durability thereof. I am aware, however, that they are capable of very great variations indetails of construction without departing from my invention, and I desire to be understood as claiming the same speeitically in the form illustrated as well as broadly.

Having thus described my invention, what I claim as no i and desire to secure by Let tors Patent is 1. In a. stove, the combination with the burners, of an oven arranged above said burners comprising a bottom having openings located above said burners. said openings hai ing downwardly and inwardly projecting flanges at their edges, damperlilze doors for said openings havingdownwardly projecting flanges at their edges adapted to lit into the flanges of said openings so that. when the doors are closed their upper faces are substantially flush with the bottom of the oven said doors being adapted j to serve as rests when opened, means for adthan is possible where it is heated by radiation through the walls ing said door jnsting said doors, and a foraniinated false bottom or shelf arranged in a spaced relation to said bottom to permit the opening of said doors.
