Patented Oct. 8, 1940 UNITED STATES PATENT OFFICE 5,. 8 Claims.

This invention relates to improvements in range constructions, and particularly to cooking ranges using wood, coal or like fuel.

I Certain disadvantages result in the application 'b of enamel or like finishing material to range castings, and it is, therefore, the primary object of this invention to provide a novel range construction utilizing enameled sheet metal parts for the I, range exterior. lb A further object is to provide novel means for mounting preformed enameled panels on the exterior of a range.

A further object is to provide a range construction having exterior enameled sheet metal panels which are protected from the influence of high degrees of heat by an air circulation arrangement.

A further object is to provide a range construction wherein air intake openings and damp- 20 ers therefor are completely concealed.

A further object is to provide a range construction wherein functional parts are substantially concealed by the use of sheet metal exterior panels to enhance the ornamental appearance thereof.

Other objects will be apparent from the description and appended claims.

I Referring to the drawings which illustrate the preferred embodiment of the invention, the nu- 50 meral t0 designates the top of the range which is mounted on a range body comprising a front ll, ends [2, back l3 and bottom 14. An oven compartment I5 is fixedly mounted in the range body between the top and bottom thereof and 55 preferably centrally of the ends, said oven being accessible by means of an oven door [6. The range front is provided with the conventional access opening (not shown) for removal of soot, etc., in the portion thereof below the oven, and is concealed by a panel I1. Compartments at B the ends of the range body constituting respectively a combustion chamber and a warming or reservoir chamber are closed by doors l8 at the range front. The range body is mounted on a base comprising legs l9 and. rails 20. A 10 splash plate or upper back plate 2| projects above the range body at the rear thereof. A suitable partition 22 extends between the bottom of oven l5 and the range bottom l4 adjacent to and defining the combustion chamber.

Within the combustion chamber and intermediate the height thereof is mounted a frame 25 in which grates 26 are journaled. Frame 25 supports fire pct 21 which tapers upwardly and outwardly from said frame and is provided with a plurality of apertures 28 adjacent its upper end. The upper margin of the fire pot 21 preferably bears against the walls of the combustion chamber. The end wall I2 of the range body at the combustion chamber is provided with an open ing 29 therein adjacent fire pct 21, and a damper 30 is adjustably mounted to control said opening. An opening 3| formed in end wall 12 below opening 29. An opening 32 is formed in the range bottom l4 adjacent opening 3|. An 30 inclined plate 33 extends between range bottom l4 and end l2 to close the combustion chamber from openings 3| and 32. An ash receptacle 34 is removably mounted on bottom l0 below frame 25 in the combustion'chamber. A feed. pouch 35 is carried by end wall l2 above fire pct 21 to project outwardly thereof and terminate inwardly of the ends of the range top l0.

A sheet metal panel 36, best illustrated in Figs. 3 and.4= is mounted at the end of the range body. Panel .36 is cut away. at 31 at its upper end, whereby feed pouch 35 may extend therethrough. Panel 36 isprovided with perpendicular flanges 38 at its vertical and bottom edges to space the panel from end wall l2, and at its upper edgeand on opposite sides of cut away 31 is provided aperpendicular flange 39 of less width than flanges 38. Integrally formed with front vertical flange 38 are a pair of inturned ears 40 extending substantially 3 parallel to panel 36, and an opening 4| is formed in part in said ear land in part in said flange 38. Edge cut-outs 42 are formed in front vertical flange 38 to accommodate hinge members (not shown) forthe adjacent door [8. In the an air passage outwardly of end wall l2.

rear vertical flange 38 are provided apertures 43. A pair of small plates 44 are fixedly secured to the range body in horizontal position at the front edge of the end wall l2, and these plates are angularly outwardly bent at 45 adjacent their rear end portions. The panel 36 is positioned at the exterior of end wall 12 with ears 40 bearing against said wall, whereby apertures 4| fit over plates 44, and the angularly bent lips 45 of said plates 44 overlie said ears 40 rearwardly of said apertures H. The parts are so proportioned that the front flange 38 lies substantially flush with range front II when ears 40 are operatively locked behind lips 45 of plates 44. Suitable stove bolts 46 extending through apertures 43-. and apertures in the seam at the rear vertical corner of the range body, serve to secure the panel 36 to place. It will be seen that this. construction substantially seals the vertical and bottom edges of the panel by abutment thereof against the range body, while space is provided at the top of the panel between the end wall I2 of the raagebody and the edges of flange 39. The panel preferably terminates in spaced relation below stove top II).

It will be observed that the panel 36 provides Thus air which passes upwardly through opening 32 in bottom l4 and through opening 3| in wall 12 passes inwardly of panel 36 as indicated by the arrows. A portion of this air flow, as governed by the setting of damper 30, enters the opening 29 and passes into and through the combustion chamber. The air in the: combustion chamber circulates under and around the fire pot to pass therein. through the grates 26 and through the apertures 28., It will be obvious that the air entering through grates 26 will provide the primary air of combustion, while the air passing through apertures 28 will provide a secondary air of combustion by which ignition of heated gaseous products of. combustion may be obtained to assure complete combustion and maximum efficiency. The heated air then passes over the oven, around theopposite end thereof, and therebelow, tov the fiue, as is conventional. The air within the panel 36 which does not enter opening.

29, exhausts at the panel, top between the end wall and flange 39. The air thus circulates and ,is directed over substantially the entire inner face of panel 36 to protect the. same against the high degree of heat generated within the combustion chamber, to protect the enameled finish thereof. At the same time the panel presents a substantially unbroken appearance to conceal the air passages, damper, etc.,v and thus enhance.

I though the air circulation feature may be eliminated. if desired.

The panel I! covering the portion of the range.

front. having the clean out opening is preferably constructed as illustrated in Figs. 6 and. '7, and comprises a panel extending flush with doors l6 and I8 by virtue of marginal inturned perpendi'cular flanges 50. In spaced relation to the ends of panel l1, brackets are secured to the panel at. the interior thereof] Brackets 5| preferably" It will bev include plate portions 52 parallel to panel I! and spaced inwardly therefrom a distance less than the width of flanges 50. Plate portions 52 are each provided with a configured cut out having large end portion 53, a reduced intermediate portion having an upper edge 54 below the upper edge of portion 53, and an inner reduced substantially circular locking portion 55 which extends above edge 54. A headed member, such as screw 56, is secured to the front H of the range body, with its head spaced: therefrom and of a size larger than out out portion 55, whereby said head may seat behind plate 52 to hold flanges 50 of panel I! tight against said front. The screws normally pass through portions 55 of the cut outs in plate 52, to operatively position the panel, and the panel I! is removable to afford access to the clean out opening in front II by a combined upward and lateral movement whereby the shanks of the screws pass through reduced intermediate portion of the cut outs to enlarged portions 53 thereof whose size permits passage of the screw heads therethrough for release of the panel therefrom. The adjacent doors l8 normally prevent such separating lateral movement, but. may be swung open to accommodate the movement.

.It will thus be seen that the normally stationary portions of the exterior panelling of the range are formed of sheet metal panels and provided with simple detachable mountings to facilitate assembly and replacement. At the same time at least some of these panels constitute parts of the air circulating system of the range to afford protective insulation for the panels, to conceal parts of the air circulating system which detract from the appearance of the range when exposed, and to accommodate a novel and effective method of air circulation. With. this arrangement is employed a novel fire pot construction which insures supply of adequate air at proper points to insure maximum efficiency of combustion. In this connection, it has been found that when the device is operated, the air which enters the fire pot through the openings 28 above the fuel bed on the grates increases effective combustion as is evidenced by tongues of flame directed inwardly from each opening and constituting combustion of the normal. incompletely consumed gaseous products of combustion. Thus a higher heat may be obtained with a given amount of fuel than in conventional range constructions, which promotes economy of operation and minimizes the accumulation of soot and like productsof combustion within the range.

It will be obvious, that in ranges of smaller sizes than here shown, where the warming or reservoir compartment is eliminated, a panel may be mounted on the stove front in place of the. warming closet door I8 (at the right in Fig. 1) by the same means as above described for mounting panel I! or panel 36.
