STOVE.

To all whom it may concern:

Be it known that we, JAMES R. BowEa and HAROLD J. Bownn, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

The object of our invention is to improve the construction of stoves in various particulars so as to render the same more con venient to use, more etlicient in use, and whereby the articles being cooked therein may be inspected without opening the doors of the oven, etc.

lVith these and otherends in view, the invention consists, first, in the provision of glazed doors at opposite sides of the stove compartments; second, in ventilating devices for the escape or withdrawal of the unconsuined gases or products thereof and odors due to cooking; third, in providing revolving platforms for the supportof articles being cooked so as to carry the latter in various rotary positions within the ovens in order that they may be more uniformly baked or roasted; fourth, providing in certain of the supports receptacles for absorbent material whose oflice is to collect drippings which may overflow from the cooking utensils carried by thesupports and, finally, in the novel construction, arrangement and combination of the several parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 l is :a view partly in front elevation and partly in transverse vertical section, of a stove embodying our improvements. Fig.2 is a longitudinal vertical section of the same. Fig. 3 is a horizontal section taken substantially through 3-3 of Figs; l and Figs. a and 5 arevertical sectional views through H and 55 ofFig. 3.

In the drawings, the reference numerals l0 designate the ends, 11 the top and 12 the bottom ofthe stove casing. This casing is divided interiorly by a vertical partition 13 and by horizontal partitions 14 and 15 to afford broiling compartments 16 and 16 at the bottom, combustion chambers 17 and 17 immediately below the stove top 11, and ovens l8 and 18 between said combustion chambers and the broiling compartments.

The ovens 18 and 18 their side Walls with bracket strips 19 to support removable grills or shelves 20. In the Specification of Letters Patent.

are provided on Patented Dec. 14, 1915. Serial No. 7,960.

front of the compartments and ovens, respectively, are doors 21 and 22 which are formed with transparent panels 21 and 22 such as of glass or mica. Also in the back of the stove are openings provided with panes of glass or mica, as indicated by 23, to admit light and to enable the interiors of the compartments or ovens to be viewed from the rear.

2% represent gas burners of any suitable type extending into the broiling compartments and in proximity to the partitions 15 to allow space therebelow for the insertion of pans containing meat for broiling.

:Gas burners are provided inthe combustion chambers 1 7 and l7 -and are eachcomprised, as shown in Fig. 2,-ofa perforated terminal tube 25 connected by a bend 25 with a flaring airinlet 25 which extends into :an oven.

26 represents the nozzle of a fuel gassupply pipe 26 whiohentersthetube -By thus forming a burner with the air inlet leadinginto an oven, the air forcombustion purposes is drawn with other gases or smokedue to cooking from the oven to ventilate the same. oSupplementary to the ventilation due :to the above described gas burner, We provide for-each oven aconical tube 27 (Fig. 2) having itssmaller enddirected toward the chunney pipe :28 which becomesloperative by reason of the suction created by the currents flowing into the chimney pipe.

Within=the oven 18 is a platform formed of-an annular plate 28 and a-circul-ar late 29,;the latter-having, asshown in Fig. 5, its upper surface in a planeslightly below the upper surface of the annular plate. Depending from the respective plates are annular ribs 28 and 29 which serve as track elements withrespect to grooved wheels 30 and 30 forthe one and 51 and el -for the other rib. :These wheels have their axles journaled in chairs .30 and 31 which are secured to the partition 15 therebelow. There are. provided three symmetrically disposed wheels foreach ofsaid plates-andare disposed to have-thoseindicated by 30 and 31 .positioned at diametrically. opposite sides of the respective plates and'mounted on a horizontal shaft 32 wherebythenotationof the shaft will, 'throughthe medium of *the referred to vwheels, impart rotary motion to the plates'in opposite directions. 83 representsa. pulley on said shaft iforan-endlcss belt 84 (Fig. 1) driven from a motor 35. About the plate 28 is a gutter 36 to receive granulated'charcoal or other material which will absorb liquids which may overflow from a pan or pans placed on the plate and thus prevent its spilling on the relatively hot oven floor or partition 15.

The object of having plates 28 and 29 rotate in contrary directions is to make a more effective display of articles within the oven 18 when the stove, for exhibition or advertising purposes, is placed in the window or an exposed position of a restaurant, or the like. Under such conditions, a large dish may be placed upon the central plate 29 and a number of smaller dishes distributed over the outer plate 28. V

In the other oven, 18", weprovide a rotary spider constituted of a hub 37 with radial arms 38 integral therewith and arms 38 which are hingedly connected to the hub by pivotal pins 39 for vertical swinging v movements so that the wheels 40 hereinafter referred to may at all times properly engage the tracks also referred to hereinafter. The arms 38 and 38 have journaled thereon grooved supporting wheels 40 and e0 whereof the latter are located at greater distances than the other wheels 40 from the axis of the spider. The arms 38 and 38 are respectively provided with branches ll .and 41 on which are rotatably mounted grooved wheels 42 and 42 of less diameters than the associated wheels l0 and 40 The wheels of each arm are disposed symmetrically about a focal point and each such group of wheels is arranged to receive in the wheel grooves a ridge to depending from a plate 43 These plates are advantageously each provided with a peripheral gutter 36 having an oflice similar to that of the aforedescribed gutter 36 of the plate 28. The spider is detachably connected to an upright spindle i-l (Fig. 1) having at its lower end a bevel gear-wheel 4:5 in mesh with a like wheel 4:6 provided on a horizontal shaft 46. This shaft is driven from said motor 7 by an endless belt 4:? passing about a pulley 48 upon the shaft. When the spindle is thus rotated, the wheels 40 and ll) track upon the floor of oven 18 and thereby impart rotary movements to the superposed plates 43. By reason, however, of the wheels 40 and 40 being located at different positions from the axes of their revolution and engaging the plate-ridges at the inner and outer diametrically opposite sides of the alternate plates, the same are caused to rotate in contrary directions in their orbital travel about the axis of the spider.

Pans or dishes are placed on the various plates 43 and furnish an attractive display of the same as they perform their several movements. The rotary plates of both ovens not only serve toshow the dishes, etc, which may be supported thereon, but also insure their being cooked more uniformly by rotating and revolving to expose the food from all sides to the hotter portions of the ovens.

In operation, the articles to be cooked are placed in the broiling compartments or the ovens with the appropriate burners em ployed, For a broiling compartment the burners 24 would be utilized, while for the ovens such burners and the burners 25 would be used according as to whether an underneath heat, a top heat or both are desirable. Pans containing articles to be baked in the ovens '18 or 18 are deposited on the plates of the respective ovens, whereupon the same are rotated or revolved through the aforedescribed driving mechanism therefor. While being cooked, or subsequently, the articles may be inspected through the glass from either the front or rear of the stove. After cooking, the heat may be reduced or stopped by suitably regulating the burners,

without interrupting the movements of the articles.

What we claim as our invention, is

1. In a stoveoven, a plurality of rotatable plates within the oven, wheels supporting said plates, a shaft extending into the oven and operatively connected to a wheel for each of the plates, said wheels being arranged so that the rotation of the shaft in either direction will cause said plates to be simultaneously rotated in opposite directions from each other.

2.
