FURNACE AND HEATER.

No. 923,697. I

To all whom it may concern;

Be it known that I, JAMES A. PENNEY, a citizen of the United States of America, residing at McKeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Furnaces and Heaters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to furnaces, and has for its primary object to provide a furnace having means for deflecting the products of combustion toward the front side of the furnace, whereby the cold air admitted to the furnace will be subjected to the action of such products of combustion, and will be thoroughly heated before being exhausted from the furnace to the rooms or compartments of a building.

An additional object of my invention is to provide a furnace with means for creating a direct draft to the exhaust flue of the furnace when the door thereof is opened and fuel is being added to the fire in t e fire-box.

A still further object of my invention is to rovide simple and easily operated dampers for controlling the exhaust of the products of combustion.

With the above and other objects in view which will appear as the invention is more fully described hereinafter, the invention consists of novel construction, combination and arrangement of arts as will be hereinafter described, and t en specifically claimed.

Referring to the drawings forming a part of this specification: Figure 1 is a front elevation of a furnace as constructed in accordance with my invention, Fig. 2 is a cross sectional view of the same partly in elevation, Fig. 3 is a longitudinal cross sectional view view taken through the exhaust casing or flue of the furnace, Fig. 5 is a vertical sectional view of a part of the furnace, and, Fig. 6 is an enlarged detail view partly in side elevation and partly in section showing the manner in which the damper operating levers are connected to the dampers.

To put my invention into practice, I provide an outer metallic shell or casing 1 which is substantially oblong in plan, having slanting walls 2 adjacent the upper end, which walls are provided with openings, from Specification of Letters Patent.

which lead exhaust flues 3. Opposite sides Patented June 1, 1909.

Serial No. 415,664.

of the casing or shell, adjacent the lower end thereof, are provided with cold air inlet openings or flues 4.

What may be termed the furnace proper, is mounted in the front wall 5 of the casing 1, and extends into the chamber or space 'inclosed by said casing 1 for some distance,

but does not occupy either the full depth or the full width of the said chamber or space, as is clearly shown in Figs. 1 to 3. This furnace pro er embodies a casing 7, the forward end of w ich'is mounted in the front wall 5 of the casing 1. The casing 7 is supported at its bottom upon brackets 6 mounted on the bottom of the casing 1, and said casing 7 is of a length so that its inner end terminates short of the adjacent wall of the casing 1, and

is of a width so that its side walls are spaced some distance away from the adjacent walls of the casing 1,- forming an air space 8 at the inner end and at the sides of the casing 7, which is herein designated-as a cold air space.

An exhaust flue or casing 9 is mounted in the casing 1 in the upper portion thereof, the forward end of said exhaust flue being mounted in the front wall of the casing 1, and the rear end of said exhaust flue 9 being mounted in the rear wall of said casing 1, the said rear end of the flue 9 being open as shown in Fig. 4 in order that communication with a chimney or stack (not shown) may be established therewith.

A fire-box or combustion chamber is within the inner casing 7, a lining of tile or similar non-fusible material 10 of any desired form is arranged within the casing 7 and supported by the bottom of the latter as clearly illustrated in Fig. 2. On the top of the fire-box lining is mounted a perforated baflle plate 12, also preferably made of tile or other non-fusible material. In the front wall of the casing 7 I have provided an openingto give access to the fire-box, which opening is normally closed by the fire door 13. A door 14 is also provided for closing the doorway to the ashit underneath the fire box or combustion c amber.

The exhaust flue or casing 9 is in communication with the chamber within the inner casing 7 by means of pipes 15 and 16, best shown in Fig. 5. The passage of the products of combustion from the furnace pro er to the exhaust flue or casing 9 is control ed by means of dampers 17 and 18 which are operated independently to open orclose the pipes 15 and 16, respeet'vely. These dempers are actuated by means of levers 19 extending through the front wall of the exhaust flue 9, as clearly shown in Figs. 1, l and 5.

In practice, when the lire door 13 is open, the damper 18 is closed, and the damper 17 is o ened, whereby the smoke and fumes from the lire-box will pass through pipe 16 directly to the stack or chimney. when the fire door is closed, the dampers are then reversed, that is, damper 17 is closed, and damper 1.8 is opened. This results in the products of combustion passing through pipe 15 into the forward end of the exneust flue 9, necessitating travel of sucl'i products of combustion throughout the length of the flue 9 before they escape to the chimney or stack. In the meantime, the cold air which enters through the inlets l is partially heated as it rises in the space 8, and is further heated by the heat given oil by the exhaust :ilue 9, so that before being discharged from the exits 3, it is in a highly heated condition. The beflle plate 12 is employed for the purpose of retarding the products of eombustion as they pass from the fire-box to the exhaust flue 9, in order that the upper portion of the casing 7 Will become thoroughly heated, and. the heat given ofl' therefrom heat the cold air rising in the cold. air space 8.

Having now described my invention, whet I claim as new 1s:--

A furnace comprising an outer CHSIDQ having outlets near its upper end for the I arm air and having cold air inlets at its lower end, a housing mounted in said casing and forming part of the front wall thereof, said housing having its side wells and rear wall spaced from the side walls and rear wall respectively of the outer casing to form :1 cold air space between said casing and. housing, :1 lire-pot within said housing, {L heliie plate arranged above said lire-pot and within said housing, an exhaust casing arranged above said housing with its ends mounted in said outer cusing, the forward end 01 said exhaust easing forming at part of the front well of the outer casing, pipes connecting said housing with said exhaust easing near the forward and rear ends of the housing, :1- dnmper within the exhaust casing for JiCll of said pipes, and indcpendei'it operating means for eiich damper, said means comprising :utuutin; rods extending through the front well of said exhaust casing.

In testimony whereof I el'lix my signature in the presence of two witnesses.
