HOT-WATER EURNACIL 1 Application filed August a1, 1927. Serial in. 216,865.

This invention relates to new anduseful improvements in furnaces and aims to provide a furnace that is constructed for producing hot air and hot water.

5 In carryin out the present invention the device inclu es generally a furnace casing within which is a fire box for heating the air within the casing from whence the same is led to the floor of the building directly above the furnace floor, the structure further including a 'hot water heating chamber that surrounds the fire box and from which the water is led to conventional radiators within the up er floors. Obviously, a building may 16 be uni ormly heated at low cost. Furthermore, the present furnace may be manufactured and marketedat a cost no greater than the ordinary hot air or hot water furnaces now generally in use.

20 In the drawings wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a fragmentary vertical section through a bliilding within which is arranged a heating plant that includes a furnace constructed in accordance with the present invention, the same being in detail vertical section. a

Figure 2 a detail enlarged horizontal section through the furnace taken substantially upon the line 2-2 of Figure 1.

Figure 3 is a fragmentary view partially in inner perspective and in vertical cross section of the water chamber of the furnace,

85 and Figure 4 is a detail fragmentary section thereth-rough.

Now having particular reference to the drawings my improved furnace consists of 40 a conventional shell or casing 5 within-which is arranged a fire chamber 6 having spaced 7 relation with the shell or casing and equipped at its lower end with a conventional fire ,grate 7. The shell or casing 5 is equipped at its upper end with a plurality of hot air discharge pipes 8, while the upper end of the fire chamber 6 is constructed with an shell or casing 5 and at its upper end with the room of the building directly above the room within which is disposed the furnace so that the cold air passes through the casing adjacent the floor. The fire chamber is formed atits lower end with an ash pit having an air inlet opening, and clean out 10.

In front of this opening the shell or casing is provided with a clean out opening that is normally closed by a suitable door 11. Forming the annular wall of the fire chamber-6 directly above the grate 7 is a water receiving unit 12. This unit consists of a circular metallic shell 14 formed or constructed at its upper and lower ends with circular water manifolds 1515. These manifolds are in communication with each other by reason of vertically extending tubes 16, while leading into the lower manifold is a cold water pipe'17 that has communication with a source of supply as suggested in Figure 1. The shell 14 of this water unit is formed with a forwardly projecting mouth 18 that affords an opening into the fire chamber 6 therethrough, this month being in registration with an opening in the shell or casing 5 over which is a normally closed door 19.

In actual practice conventional water ra"- diators 20 are arranged in the upper floors of the building, and thathave communication at certain ends with the upper manifold 15 of the water unit by reason of pipes 2121. The pipe 21' is bent over the top of unit through the radiators and thence returned into the lower manifold as clearly disclosed in thediagrammatic view in Figure 1.

In view of the foregoing'description when considered in conjunction with the accompanying drawings it will at once be apparent that I have provided a highly novel, simple, and extremely useful hot air and hot water heating furnace that is well adapted for all the purposes heretofore designated, even though I have herein shown and described the invention as consisting of certain detailstructural elements, it is nevertheless to be understood that minor changesmay be made 5 therein without affecting the spirit and scope of the appended claim.

. Having thus described the invention, What I claim as new is v In a furnace of'the character described, 8.

fire box formed with a circular wall, a water 10 manifold at the upper and lower ends of the:

wall, tubes formed on the inner surface of the wall and connecting the manifolds, an

outlet pipe for the upper manifold, and an inlet pipe for the lower manifold. 15

r In testimony whereof I aifix my signature.

CHARLES 'J. STRICKER.
