0001: AND HEAT STOVE.

Application filed November 10, 1924. Serial Ito. 748,918.

This invention relates to combination cooking stoves and heaters, the primary object being to provide a cooking stove in the oven space of which is a novel form of a boiler or hot water heater so that the cooking stove will perform a dual function, that .of cooking the meal and furnishing the necessary heat for raising the temperature in distant rooms, the hot water heater being adapted to be connected to radiators in rooms distant from the one in which the stove is located.

The invention contemplates certain novel arrangements of parts which provide for efficiency, ease of assembly and control as well as means for heat insulating the water heater when it is desired that the stove function independently of the water heater. The novel features of the invention will be clearly understood by reference to the following description in connection with the accompanying drawings, in which- Fig. 1 is a perspective view of a combined cook stove and water heater constructed in accordance with my invention, parts being broken away to better show other parts.

Fig. 2 is a' rear perspective view of the stove embodying the invention, part of the rear wall being broken away.

Fig. 3 is an elevational view of one of the boiler sections, the baflie plate and the manifolds being shown in section. T

Fig. 4. is an end view of the water heater or boiler.

Fig. 5 is a fragmentary perspective view of one end of the water heater-or boiler showing a heating insulating baflie, and

Fig. 6 is a perspective view of a damper.

The stove l in its general aspect conforms to a cook stove. It is provided with the usual fire box 2 having the grate 3 of appropriate construction, a flue 4 passing through an oven 5 above the top plate 6 of the stove. The back and front of the stove on their ,inner faces are preferably smooth so as to prevent lodging of dirt, soot, etc.

Between the front plate 7 and the back plate 8 is the normal oven space 10 of the stove and it is divided from the. ash pit 11 by a vertical partition 12 extending from the bottom of the stove but not quite to the grate. Instead of the oven in the oven space, I provide a water heater. The water heater consists of a plurality ofwater heating sections13 connected together by the manifolds 14 and 15, one being an inlet and the other an outlet. The sections are hollow and each section is provided with an elongated top portion or leg 16 horizontally of greater length than the bottom or short leg 17. Both legs communicate through spaces or openings 19 through which the products of combustion may pass as well as passing through the spaces between the spaced sections as will be well understood.

The front ends of the boiler or hot water sections are provided with curved baffles '20 and 21 which are directional baffles for directing the products of combustion easily into the spaces between the boiler sections and for directing the products of combustion against the manifold 14.

It will be obvious that the top edge of the.

long leg of each manifold is substantially;

horizontal throughout itslength, that it has no upstanding off-set portion, either at its.

front or rear end such as may be found in some types of boiler sections. The purpose of the peculiar construction of the boiler section isto provide one in which there can be no insulated space or dome to contain trapped-air or vapor.

I have found that when the sections are all arranged together so that the top of the boiler or heater will be spaced an equal distance from the top plate of the stove that the between the sections so that the flames or hot gases may pass along the upper portions of the sections and then over the rear edges of the plate 24 and back over'the short legs 17 before they enter the flue 4 which communicates with the space 25. Therefore a high state of efiiciency may be maintained for the stove for not only will it be adapted for use as a cook stove but it will also heat water so that the boiler may be connected by suitable pipes to radiators in, distant parts of the building. Of course the boiler is supplied with water by any suitable means as for example through a water pipe 26 and suitable control devices such as expansion in the flue 27 and'having a crank or handle 29'by which it may be turned to vary the effective port area between the flue 27 and the flue 4. The damper 28 is illustrated in Fig. 6 as being in the form of a mutilated cylinder 30 with end disks 31 and 32 and the application of the damper is shown in Fig. 2.

In the summer time it will be desirable to eliminate the use of the hot water heater or boiler, the hot water system at this time being drained so in, order to prevent the boil er sections from burning out, due to the heat in the fire box, I provide an insulating shield 33 having a flange 34 adapted to be fastened to the pan.22 by the fastening device 35, the

shield or baffle 33. being L-shaped in cross section so that it will fit over the upper edge of a hot water heater and eiztend down to the grate, thereby eliminating possibility of water, gas or flame passing thro'ugh the boiler sections or heater. In the winter time the bafile may be removed.

In order to provide a convenient meansv for assembling the boiler with respect to the .stove, the sections are all connected as shown in Fig. 4, then the hinged door 36 at the end of the stove is swung open on the hinges 37 and 38, then the entire boiler can he slid longitudinally into the stove. The necsssary connections for the manifolds 14 and 15 will then meet and the door 36 may now be closed.

' When it is desirable to remove the boiler or heater, the manifold connections maybe loosened, the door 36may be opened and the entire unit may be slid out of the stove for inspection or repairs.

It will be observed from the foregoing that the invention contemplates a novel, easily constructed and eflicient means for combining in a cook stove, the boiler which receives its heat from the products of combustion passing through the oven space of the stove so that the stove can serve ,a' dual purpose of cooking food and supplying the necessary 'heat for heating the building, thereby doing away with the necessity of having a separate heating unit distinct from the cook stove.

What I claim and desire to secure by Let- I ers Patent is a 1. A water heating unlt, comprising a plurality of communicating sections, each section having a horizontal long leg and a horizontal short leg below the long leg, one

end of the long leg on each section having an inwardly and upwardly directed along its front upper corner. I

2. A water heating unit, comprising a plurality of communicating sections, each' section having a horizontal long leg and a horizontal short leg below the long leg, one endof the long leg on'each section having an inwardly and upwardly directed bafile along its front upper corner and a. parallel baflie below it.

'3. A cook stove having an oven space and a water heating unit in the oven space, the water heating unit comprising'a plurality of parallel spaced communicating sections, each section having an upwardly and inwardly directed bafile at its front upper corner, each baflie being one-half the width of the space between the sections, the complementary bafiies abutting end to end.

In testimony whereof I afiix my si -nature.

ALFRED L. sMITH.
