Application filedA July 30, 1897.

To all whom t may concern:

Be it known that I, JOHN ERBEN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improvements in Stoves or Ranges; and I do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which io it appertains to make and use the same.

My invention relates to stoves and ranges and seeks to improve that type of stove and range which comprises a casing, an oven disposed above the bottom wall of the casing so as to form a lower horizontal flue and having its side walls arranged at a distance from the side walls of the easing so as to form vertical flues in communication with the lower horizontal flue, an ash-box of less width than the 2o oven arranged above the middle of the same, a fire-box arranged above and corresponding in width at its bottom to the ash-box and having outwardly-flared side walls serving in conjunction with the top of the casing to form z 5 horizontal iues,and an upright iiue connected with the lower horizontal iiue.

The invention will be fully understood from the following description and claim when taken in conjunction with the annexed draw- Figure l is a vertical transverse section of a stove or range embodying my invention, and Fig. 2 is a vertical longitudinal section taken in the plane indicated by the line a: m

of Fig. I.

Referring by letter to the said drawings, A indicates the casing of my improved stove or range, which is preferably constructed of steel plate and is of the ordinary rectangular 4o form. This casingAhas a plurality of holes a in its top wall b, which are normally closed by removable lids c, and it is also provided on said top Wall b with a collar-flange d, which surrounds an opening CZ' and is designed for the ordinary connection of a smoke-pipe e, as

shown in Fig. l of the drawings.

B indicates an upright flue which is ar ranged at the back of the stove or range in communication with the opening d in the top 5o and has the openingg below the top for a purpose presently described, and C indicates Serial No. 646,541. (NO model.)

an oven, both flue and oven being preferably constructed of steel plates. The said oven C extends from the flue B to the front of the casing, where it is provided with a door D, and it is disposed about the proportional distance illustrated from the end Walls h of the casin g A to afford flues E and is also disposed about the distance shown above the bottom wallfof the casing to form a Hue F, which is 6o in constant communication with the fines E, as shown, and is preferably provided with a cleaning-door G. The iiues F and B are connected by an opening c', (see Fig. 2,) and in order to prevent a too direct passage of smoke and products of combustion from the flues E to the flue B the vertically-disposed bafflestrips II are provided in the ue F, as shown. These strips Il extend from the rear wall L of the line F to a point adjacent to the front 7o Wall of the casing A, and, being disposed on either side of the opening t', they serve to cause the smoke and other products of combustion to pass in close proximity to all parts of the bottom wall of the oven, so as to insure an even heating of said wall throughout its area. The said strips Il are connected to the casing-Wall f and the bottom wall of the oven by bolts j, and they are consequently enabled to serve the additional function of supports 8o for the oven, as will be readily appreciated.

Above the oven C is disposed an ash-box I, which has a door J for the convenient introduction and removal of an ash-pan K. This ash-box I extends from the flue B or from the inner rear wall L of the stove to the front wall thereof; but it is considerably less in width than the oven C and is disposed above the middle of the same, as best shown in Fig. 2, so as to expose a considerable portion of the 9o area of the top wall 7.; of the oven to the direct contact of the products of combustion, as will be presently pointed out.

Above the ash-box I is disposed the firebox M, which extends from the Wall L to the front wall of the casing A and has a suitable grate N in its bottom, as shown. At its bottom this lire-box M corresponds in width to the ash-box I; but from such point its side walls P are dared so as to increase its carco pacity and afford a larger surface of fire, which is desirable in order to evenly heat the top wall b ot the casing. The said walls P merge at their upper edges into horizontal Walls Q, and these walls Q, which serve in conjunction with the top casing-Wall b to forni a iiue or iiues R, merge, in turn, into depending Walls or skirts S, which form the vertical flues E in alinement with the tlues E, and serve to preventa direct passage of the flame and products of combustion to the top Wall of the oven C, and thereby obviate a too high heating of said Wall, Which would result in scorching the top of the substance being baked. This is an important feature of my invention, because it effeetually prevents scorching of the top of the article being baked before the other parts of the same are cooked, which is adesideratum. The depending walls or skirts S also tend to prevent the deposit of soot and other products of combustion on the top wall C, and consequently the said Wall will be sufficienti y heated, notwithstanding the fact that there is no direct passage of the flame and products of combustion to the same.

T indicates a damper for controlling the opening g. This damper T is shown as fixed to and movable With a rock-shaft having a crank at one end; but it is obvious that it might be opened and closed in any suitable manner and through the medium of any preferred device. Said damper T is designed to be opened When a iire is Iirst started to permit of a direct passage of the smoke and other products of combustion to the smoke-pipe e; but when the iire is Well started it is closed, so as to compel the smoke, dames, and other products of combustion to take the course indicated by arrows. This course is from the re-boX through the iues R, the iiues E; the flue F, the opening t', and the flue B to the smoke-pipe E. In consequence of such passage of the flame and other products of combustion it will be observed that the top, side, and bottom Walls of the oven will be subjected to a uniform degree of heat, which will preclude the possibility of any part of an article in the oven being baked faster than the remainder thereof.

It Will be observed that by reason of the construction of the tire-box M and the arrangement ot the same adjacent to the top Wall of the casing the said top Wall will be highly and uniformly heated throughout its area, so as to quickly cook any substance that may be placed in cooking utensils thereon. Again it Will be noticed that the arrangement of parts described permits of the oven being made very large Without the necessity of the casing being any larger than thecasing of an ordinary steel-plate range, Which is an important advantage and a desideratum in stoves and `ran ges.

Having thus described my invention, what I claim is- The stove or range described comprising essentially a casing, the oven disposed above the bottom wall ot the casing so as to form a low horizontal flue and having its side Walls arranged at a distance from the side Walls of the casing so as to form vertical lues E communicating with the lower horizontal flue, the upright flue D connected With the low horizontal flue, the ash-box of less width than the oven arranged above the middle of the same, the fire-box arranged above and corresponding in width at its bottom, the horizontal Walls Q forming continuations of the side walls of the fire-box and serving in conjunction with the top of the casin g to form upper horizontal flues R, and the skirts S depending from the outer edges of the Walls Q; the said skirts serving in conjunction with the side walls of the casing to form vertical fiues E disposed in a plane above the oven and coincident with the liues E, whereby the iame and products of combustion are conducted down to the lower horizontal iiue and a direct passage of flame and products of combustion to the top Wall of the oven and the deposit of soot and ashes thereon is prevented, as and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN ERBEN.
