HEATING STOVE 0R FURNACE.

SPECIFICATION forming part of Letters Patent No. 367,777, dated August 9, 1887.

Application tiled October 29, 1883. Serial No.110,250. ('No model.)

To all whom it may concern:

Beit known that I, EDGAR W. ANTHONY,0f Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a certain new and useful Improvement in Heating Stoves or Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature, in which Figurel represents my invention as applied to a furnace, and shows in perspectivea portion of thecasing of the stove and a part of the interior thereof, the section being broken away to expose it. Fig. 2 isavertieal section thereof.

Fig. 3 is a view, part in plan and part in section, to illustrate a detail of construct-ion. Fig. 4 shows in vertical section the upper portion of the radiator. Fig. 5 is a section of a plug. Fig. 6 is a section, and Fig. 9 is a plan, of the deflector. Fig. 7 is a section of the lower part of the radiator. Fig. 8 is a plan view of the upper part. Fig. 10 is a plan of the lower section of'the radiator.

The invention relates especially to the construction of the radiator, whereby a largera diating-surface is obtained and the heat caused to be uniformly radiated from all sections thereof, and also whereby it may be revolved before it isset, thus providing means for connecting the combustion-chamber with the smoke-pipe regardless of the position of the furnace.

It also relates to various details of construction, all of which will hereinafter be more fully specified.

Referring to the drawings, A represents the ash-pit, B the fire-pot, C the combustion-chem ber, D the radiator, F the air-heating chamber, and M the outer casing, of the furnace; m,the door to the combustion chamber; m, the ash-pit door; of, the door to the air-heating chamber F.

The radiator D comprises, essentially, three parts: first, the lower section, (7., second, the upper section, d, and, third, the deflector (1 The lower section, d, has the circular flange d surrounding the opening (1*. This flange is adapted to shut into a groove or recess, d cast or otherwise formed in the upper edge of the shell or casting d, forming the combustionclosed by the plug (1 chamber. From this flange d the sides of the lower section spread outward and upward, but not at the same inclination, the upper edge of the lower section being curved inward and outward, as represented in Figs. 3 andlO, so that when the deflector (Z is in place a series of connected passages, (1 connecting the combustion-chamber with the chamber within the radiator, are formed. The deflector d is shaped substantially as shown in Figs. 2, 7, and 8that is, it is an inverted-cone-shaped plate having a central opening, (1 which is The deflector has a flange, d, which rests upon suitable projections, d, extending inward from the side of the lower section I prefer thatthe deflector be shaped substantially as represented in said Figs. 2, 7, and

S, and when so shaped the passages d in the under section, d, about it are connected with each other-that is, there is a continuous passage about the radiator, which is enlarged at regular intervals by means of the outward turns or curves of the said section. These outward turns or curves, of course, also increase the heating area of the section.

The deflector is provided with the hole d, in order that soot or dust that may lodge therein or in the upper portion of the furnace may be dislodged therefrom upon the removal of the plug (i and I prefer not to attach the deflector rigidly by bolting or otherwise to the lower sect-ion, in order that it may be turned or jarred to facilitate such removal. The upper section, cl, of the radiator-is shaped to substantially the same form as the upper edge of the lower section, and fits into the groove c in the upper edge thereof.

In order that the heat may be caused to be properly deflected by the deflector-,it is desirable of course that the entrance to the escapeport of the furnace, instead of being located at one side of the radiator-of the furnace, as is common, should be arranged centrally over the deflector, so that the heat may be drawn or ascend from the combustion-chamber uniformly nponall sides of the deflector, and this would. not occur if the entrance to the escapeport were not so placed; and I find that it is more desirable not only to have it centrally located in relation to the deflector, as above described, but also to bring it well down from the top of the radiator, in some instances almost or quite within the upper edge of the deflector-plate. In the drawings this opening or escape-port, which is marked E, is shown a little above the upper edge of the deflectorplate. By this construction it is obvious that the draft of the furnace will draw the heat or that the heat as it ascends will be deflected by the detieetoragainst the wall of the lower section uniformly throughout the extent of the deflector and in all its passages, and will cause it to strike or impinge against the side and upper wall of the upper section, from whence it wiil take a downward course into the escape-port E. This escape-port E, I prefer to have enlarged from its lower edge, e, to the point e, where it enters the section, flue, or passage 0 and this section, flue, or passage may be formed by the flue-plate c", which may be cast with the upper section of the radiator; or it may be made separately therefrom and attached thereto, and it may extend horizontally therefrom, as represented, and from a somewhat oval shape assume a cylindrical shape, as represented in Figs. 2 and 4. As many furnaces require to be low, this construction will be found to be very desirable, as it does not increase the height of the furnace and allows the connection with the smokepipe to be made at a point below the upper surface of the casing M; but I do not confine myself to this specific construction, because the passage from the escapeport E may extend up through the radiator and shell M and then connect with a vertical smoke pipe or by means of a suitable elbow with a smoke-pipe having any other direction.

By making the flange (1 of the lower section circular I am enabled to revolve the radiator in relation to the shell d, so as to bring the passage or flue 0* into any desired position in relation to the rest of the furnace. Of course, this result would be obtained if the lower and upper sections were circular.

it will be observed that the opening 11 in the deflector-plate can be reached from the opening in? to the combustion -ehamber by means of a stick or red, and that the plug can be pushed up and soot easily dislodged from the upper surface of the deflector.

Of course, I can attach the deflector-plate D to either the lower or upper section if I desire, and I may make the deflector of any other suitable configuration if I wish without departing from some of the features of the invention, although I do not mean by this to be understood as not also claiming the deflector and sections in the shapes represented.

Of course, thejoints of the furnace between the two parts of" the deflector and the lower section of the deflector d, are packed in the usual manner after the radiator has been located to bring the flue a" into proper position.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- In a heating stove or furnace, the combination of the section (1 of the radiator, the plate 0, formed integral therewith and shaped to provide the-horizontal central opening, E, and the lateral passage 0' from said central opening to the exterior of the stove or furnace, the section (Z of the radiator, having fluted sides, as described, and the circular flange dffland. the deflector-plate (1", arranged within and supported by the section (I of the radiator, as and for the purposes described.
