LOUIS B. PIPER, OF CHICAGO, ILLINOIS.

FURNACE.

To all whom it may concern:

Be it known that I, LoUIs B. PIPER, a cltizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Furnaces, of which the following is a specification.

lWIy invention relates to improvements in;

furnaces and has for its object the produc tlon of a furnace of improved constructlon and operation.

My lnventlon consists 1n the comblnatlon and, .ar-ra'ngement of parts hereinafter described and claimed.

My invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a vertical section of a furnace embodying my invention, Fig. 2, a horizontal section of Fig. 1, Fig. 3', a partial section on line ma' of Fig. 1, Fig. 4:, a vertical section of a modified form of construction, and Fig. 5, a horizontal section of Fig. 4:.

As illustrated in Figs. 1, 2 and 3 the preferred form of construction comprises a square interior radiator chamber 1 supported on suitable supports 2 and provided with the usual fire pot 3 and grate 4. Suitable draft fiues 5, 6 and 7 are provided for radiator chamber 1 the o eration of which will be readily understoo by those skilled in the art. Surrounding radiator chamber 1 is an exterior square casing 8 which incloses an air space 9 around said radiator chamber. Diagonal vertical partitions 10 are secured to chamber 1 at each corner and vertical partitions 11 are secured to the sides of said radiator chamber between said diagonal partitions as shown. To the partitions 10, upwardly and inwardly inclined bafile plates 12 are secured, and similar battle plates 13 are secured to partitions 11 to alternate with partitions 12 and with each other as shown. A space 14 is left between the inner edges of battle plates 12 and 13 for the upward passage of air adjacent the walls of chamber 1. A suitable air dome 15 is formed over chamber 1 and one or more furnace pipes 16 are designed to lead therefrom to the registers. By this construction it will be observed that air will be drawn into the chamber 9 and follow an upward tortuous path through bafiile plates 12 and 13 into air dome l5 whence it will pass to register pipes 16. In its passage through chamber 9 the Specification of Letters Patent.

Serial No. 520,396.

air will be retarded and thoroughly heated by the action of the baffle plates 12 and 13, the upward and inward inclination of which constantly tends to cause said air to pass through spaces lt adjacent the outer walls of radiator chamber 1 which, of course, are

the hottest a ailable portions of the furnace.

In the form of construction illust ated in l Figs. a and 5 the radiatorrchamber 1"and casing 8' are made cylindrical in form, and radiating vertical partitions 11 are provided in air chamber 9. Upwardly and inwardly inclined battle plates 13 are secured to partitions 11 with their inner edges located at a short distance from chamber 1 so as to leave air passage 14 adjacent thereto.

While I have illustrated and described the preferred construction for carrying my invention into effect this is capable of variation' or modification without departing from the-spirit of my invention. I, therefore, do not'wish to be limited to the exact details of construction set forth but wish to avail my self of such variations and modifications as come within the scope of the appended clhims.

\Having described my invention what I claim as new and desire to secure by Letters Patent is: i

1. In a furnace, the combination of an interior radiator chamber; an exterior casing surrounding said radiator chamber and spaced therefrom; upright partitions in the space between said radiator chamber an said casing; and alternating batlie plates on said partitions, the said baffle plates being given an upward and inward inclination, substantially as described.

2. In a furnace, the combination of an interior radiator chamber; an exterior casing surrounding said radiator chamber and spaced therefrom; upright partitions in the space between said radiator chamber and said casing; and alternating bafile plates on said partitions, the bafiie plates being given an upward and inward inclination, and of such width as to leave a space between their inner edges and said radiator chamber, substantially as described.

3. In a furnace, the combination of a square interior radiator chamber; a square exterior casing surrounding said radiator chamber and spaced therefrom; diagonal vertical partitions secured to said radiator chamber at each corner; vertical partitions secured to the sides of said radiator chamward inclination, and of such width as to leave a space between their inner edges and said radiator chamber, substantially as de- 15 scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS B. PIPER.
