UNITED STATES PATENT OFFICE.

JOHN H. AND GEORGE POI-IL, OF PLYMOUTH, INDIANA, .ASSIGNOR-STO KEY- STONE FOUNDRY COMPANY, OF PLYMOUTH, INDIANA, A CORPORATION OF INDIANA.

Application filed May 25,

To (All whom it may concern-t Be it known that we, JO N HERMAN Min- LER and GEORG Por L,'citizens of the United States of America, and residing at Plymouth, in the county of Marshall and State of Indiana, have invented certain new and useful Improvements in Laundry Stoves, of

' plate is nearly horizontal from sideto side and besides are substantially horizontal from which the following is a specification.

The object of our invention isto produce an improved laundry stove.

More specifically, one of our objects is to produce. a laundry stove having a fire pot elongated to receive lengthsof fire wood in common use, with a deflector-plate over the rear of the fire pot to force the products of combustion to the front and sides of the stove top before passing out of the smoke flue.

A further object is to provide a water heater capable of use as a deflectonplate in a stove of the type described.

Further objects antl'beneficial results of, our invention will appear as the details of the preferred form are described, with reference to the accompanyingdrawings, in

which:

Fig. 1 is a plan View of a stove embodyin'g our invention, with a part of the top removed to show the combined deflectorplate and water heater.

Fig. 2' is a side elevation of the stove showing a portion of the stove and the deflectorplate in section.

Fig. 3 is a front elevation of the stove.

'Fig. 4 is a plan view ofthe combined deflector-plate and water heater.

Fig. 5 is a side elevation of the same.

Fig. 6 is a sectional elevation on the line 6+6, Figs. 4 and 5.

Figs. 7 and 8 are rear tions, respectively, of the combined deflector-plate and water heater. I

The stove isv shown mounted on a base, 10,

fire pot shown in dotted lines in Fig. 1.

Thetop, 13, of the stove is approximately square, and is somewhat longer and considerably widerthan the firepot. The sides of the fi repot slope outwardgently to the line, 141, from whence they spread rapidly, to where they meetthe top near itsedge.

LAUNDRY s'rov 1922. Serial No. 563,479.

A combined deflector-plate and water back or water heater, 15, is shown substant ally covering the rear halfof the'fire pot. At the rear of member 15 inlet and outlet pipes, 16 and 17, are shown and at the front a projection, 18, reaches forwardly and upwardly to the stove top. The rear of the front to back; butthe front of the plate is products of combustion are deflected toward the front and center of the stove top. An opening, 20, through the plate provides for the passage of some of the products of com bastion directly through the plate to the middie of the rear of the stove top, and thus aids in heating the water inthe hollow plate and at the same time providesfor heating the stove top over the plate. I c

As, shown by dotted lines in Fig. 3, the front outside corners of the hollow plate are sloped substantially the same as, the

stove sides at that point, and thus the plate the stove over the edges of the plate to I smoke flue, 21, heat the portions of the rear of the stove top between the edges and the s middle, heated through passage 20. and front eleva- J In this way it will be seen that we provide astove with an elongated fire pot and square topand having a combined deflector-plate and water heater which will at the same time heat water and deflect the products of combustion so that they will heat the entire stove top, and especially the front portion of it. If some such plate were not used the products of combustion tend to pass directly to the smoke flue, and so would heat the stove top but little, except for a small place just in frontof the flue.

It will be further noted that two regulable drafts are provided, one at 22, nearthe bot tom, shown at the. front, though not necessarily so located, and the other at 23, near.

e5 curved upward in the middle, and thus the I K the top of the stove in front, as it needs to be for the best results in the combination shown. By regulating the lower draft, the rapidity ofcombustion is largely controlled, and by regulating the upper draft the proper amount of air may be admitted for completing combustion. At the instant if this completion of combustion the flame and products of combustion are in contact with the top of thestove, and travel along a great portion of the top before reaching the smoke flue. Because of the shape of the plate, the passage between it and the sides of the stove as well as the passage 20, the products of the initial combustion passing up through these passages are spread out in sheets so that they will contact well with the draft from inlet 23 carrying the additional oxygen needed to complete, combustion. The plate is so curved that the side passages are widest at the points where they direct the gases towards the rear corners of the stove top which might otherwise tend to become cold. Inthis way the entire stove top is heated, and much of the combustion takes place in contact with the top, so that the stove is very efiicient for the purpose for which it is intended. v I

Having described our invention and the preferred embodiment thereof, its purpose "and the manner of its use will be understood without further description; and it will be understood also that the benefits of several features may be retained at'least in I top,;sides sloping outward and upward from the pot to the top, there being a smoke outlet in the rear of the stove top, and a deflector-plate between the pot and the smoke outlet, the front of said deflector-plate forming an arch having its ends resting on the sloping sides and its center supporting the stove top. e
