FURNACE.

Specification of Letters Patent;

Patented July ib-3, 1915 Application filed. March 19, 1915. Serial No. 15,480.

To all whom z't may concern:

Be it known that I, JOHN BROUWERS, a citizen of the United States of. America, residing at Sparta, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in F urnaces; and]: do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to furnaces, and it is an object and purpose thereof to provide new and improved constructions in furnaces which permit the ready assembling of the furnace with a minimum of trouble and expense.

It is a further object of the invention to provide means dividing the chamber in which air is heated in the furnace into a plurality of compartments from which heated air must escape through an associated furnace pipe leading to a room in the house heated by furnace, whereby the pipes of shortest length in the furnace do not pass practically all of the heated air While the longer pipes pass but very little to the rooms with which they are connected.

Still further objects consist in the provision of a furnace located horizontally and having a new and improved construction dividing the body thereof into a fire box with an ash pit below it, While the upper portion of the body is divided from the fire box to produce a passageway to the chimney whereby all the products of combustion are brought into close contact with the air heating chamber so that the heat from said products may be given off, in a great measure before reaching the outlet chimney.

Various other objects and purposes con-Y sisting of a pivotally mounted baffle wall for controlling the draft and in guard members keeping the fire in the furnacefrom the walls of thebody to prevent its burning out, will be apparent as understanding is had of the construction shown in the accompanying drawings, in which:

Figure 1 is a front elevation of the furnace. Fig. 2 is a vertical section taken transversely thereof. Fig. 3 is a vertical section taken longitudinally of the furnace. Fig. 4 is a front elevation of the grate with the guard members applied thereto; and Fig. 5 is a plan view of the grate, the guard members being shown removed from one side of 'for the purpose of illustration.

said grate. Fig. 6 shows a view similar to Fig. 3 of the front part of a modified form of furnace construction.

Like reference characters refer to like parts throughout the several views of the drawings- In the construction of the furnace a cylindrical body is formed including a lower semi-cylindrical half 1 which, at its edges, is turned outwardly to form horizontal flanges 2', and at its front and rear having integral flanges 3 and 4 projecting vertically therefrom. The body is completed by an upper semi-cylindrical half 5 which, at its edges has outwardly extending flanges 6 adapted to seat on the flanges 2. Flanges 2 and 6 are connected together forming an open ended cylinder. The member 5 is further provided with the inwardly extending horizontal flanges 7 opposite flanges 6 and at its front and rear edges with outwardly extending flanges 8 and 9 completing, with the flanges 3 and 4, heretofore described, bearing rings towhich the front and rear of the furnace may be secured.

The front of'the furnace indicated at 10 is detachably attached to the body thus formed by means of bolts 11 through flanges 3 and 8 and in the same manner the back 12 is attached by bolts 13 to flanges 4 and 9. If desired the front and back may be extended laterally to each side and also above the cylindrical body to form a boundary for the chamber, saidchamber being completed by sides 14 connected by a top 15. In the top a plurality offurnace pipes 16 are secured serving as conduits toconvey heated airfrom the air chamber to rooms of the house in which the furnace is installed. A. cold air inlet passage 17 may be entered into the air chamber in any convenient manner, the one shown in the drawing being merely It is of course apparent that the front and back 10 and 12 need not be extended to form the front and back of the air chamber but that the thin metal like that forming the top may be used to form the front and-back of the air chamber while the front and back 10 and 12 need extend only to the edge of the flanges 3, 4, 11 and 13 as shown at 10 in Fig. 6, this construction howevergnot changing any principle of operation.

Previous to the connection of the front 10 to the cylindrical body, a baiiie 18 having a curved outline and provided with a back 19 formed as a segment of a circle is introduced into the body by sliding it inward on the flanges 7 Baffle 18 is secured to the front 10 by means of bolts 20 to hold it rigidly in place. When so positioned the back 19 is located a distance in front of the back 12 of the furnace and the top of the baffle is positioned a distance below the top of the cylindrical body previously described. A grate 21 of any approved construction is supported a distance above the bottom of the lower member 1 and at its rear end carries a baffle wall 22 hinged to a rod 23. An operating rod 24 is connected to the bafile wall and extends rearwardly through the back 12 and has a series of notches 25 cut therein on its underside which engage with the lower edge of the opening through the back. Rod 24: terminates in a handle 26 by means of which it may be manually operated to position the baffle wallin various positions with respect to the grate.

The back 12 has an o ning therein nor mally closed by a door 2% at the upper portion of the body, while another door 28 closes an opening adjacent the lower portion of said cylindrical body. Similarly the front 10 has an opening therethrough normally closed by a door 29 directly above the member 18 and two doors 30 close openings in the front 10 which lead into the fire box formed by the grate 21 and the baflie 18. Below the grate 21 an opening is formed in the front 10which is closed by the doors 31 through which access may be had to the ash pit located below the grate. Near its forward end the upper member 5 of the cylindrical body has an opening and a pipe 32 is connected to said member 5 in conjunction with this opening to carry away the products of combustion.

The air chamber formed between the cylindrical body and the outer inclosing members 14 and 15 is divided in its upper half by a plurality of vertical partitions 33 which on their lower edges are cut to fit closely against the upper half 5 of the cylindrical body and rest on the flanges 6 thereof, being formed at their outer edges to fit closely adjacent the inclosing members 14 and 15 of the air chamber. These partitions are positioned between the furnace pipes 16 and divide the upper half of the air chamber into a plurality of compartments from which any escape of air must be through its associated pipe 16 as will be readily understood. Instead of pipes 16 extending vertically from the air chamber at the central portion thereof as shown in full lines it may be desirable to have a larger number of pipes, especially with larger sizes of furnaces, and these may be positioned at an angle to the top 15 as shown in dotted outline at 34 in Fig. l and each of the compartments between partitions 33 may be further divided by a vertical partition wall 35 so 7 that each pipe 3 1 will have connection with guards 38 which at their lower ends are detachably seated in the openings. These guards form a substantial barrier between the fire and the sides of the body preventing the fire from contacting with and burning through the body as would otherwise occur, while any guard 38 that becomes burned so as to be useless may be removed at will and a new one used in its stead.

Nith a' furnace thus constructed it will be apparent that products of combustion are carried over the bafile wall 23 and under the back 19, passing between it and the back 12 of the furnace and thence forward between the baflle l8 and the top of the cylindrical body to the chimney 32. The products of combustion thereupon come in contact with the upper portion of the cylindrical body practically its entire length and heat given off therefrom will heat the air in the air chamber of which the upper portion of the body forms one boundary. The heated air passes out through the furnace pipes 16 or 24: and it is impossible for the air in one compartment to escape except through its associated furnace pipe. This construction is very easily made and quickly assembled. The upper and lower members 1 and 5 of the cylindrical body are readily cast as is also the front and back and the bafiie 18 together with the grate and the guarding members 36 and 38 associated therewith. The assembling of the baflle 18 in the furnace is especially simple and effective. There are no parts outside of the grate and guards 28 that are liable to become useless and these may be readily replaced at any time. The baflie wall 22, by reason of its adjustable relation to the grate, may be swung to vary the passage of the products of combustion from the fire box over said wall and adjusted to conform to the particular circumstances under which the furnace may be used, while the location of the doors 27, 28 and 29 permit a very ready cleaning of the furnace at any time with little or no attendant trouble.
