HOT-AIR CIRCULATOFI.
Specification of Letters Patent.
Patented Oct. 3, 1905.
Application filed December 18, 1904. Serial No; 236,766.
To all whom it may concern:
Beitknown thatl, MILT N O. GREEN, a citi- Zen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Hot-Air Circulators, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to improvements in hot-air circulators; and it consists of the novel features herein shown, described, and claimed.
In the drawings, Figure 1 is asectional elevation of my hot-air circulator applied to a heating-stove, the stove being shown in elevation. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1 and looking downwardly, as indicated by the arrow. Fig. 3 is a horizontal section on the line 3 3 of Fig. 1 and looking downwardly, as indicated by the arrow.
Referring to the drawings in detail, the outer shell 5 has a bottom 6 and a top 7, there being a nipple 8 extending downwardly from the bottom and a nipple 9 extending upwardly from the top. The nipple 8 is intended to be inserted through the top 10 of the stove and the nipple 9 is intended to be connected to the stovepipe or chimney, so that the smoke and gases from the stove 11 will pass upwardly through the nipple 8, through the shell 5, and through the nipple 9.
The inner shell 12 is funnel-shaped and has a cover 13 rigidly secured, so as to form a hot-air chamber 14. A nipple 15 forms a passage through the wall of the shell 5 into the chamber 14:, and a nipple 16 forms a passage from the chamber 14L upwardly through the top '7. An elbow 17 is secured to the outer face of the shell 5 to communicate with the nipple 15, and the pipe 18 extends from the,
floor up to the elbow 17, there being an inletopening 19 at the lower end of the pipe, so that the cold air will pass from the floor through the opening 19, upwardly through the pipe 18, through the elbow 17, through the nipple 15 into the chamber 14, where it will be heated and pass upwardly through the nipple l6 and be discharged into the room.
The smoke and hot gases from the stove will pass slowly through the chamber 20 in the shell 5 around the inner shell, and the I heat will be absorbed by the inner shell and imparted to the air in the chamber 14:, thereby causing a strong draft of air to circulate through the device. 7
I wish to call especial attention to the funnel-shaped inner shell mounted with its point directly above the center of the nipple 8, so that this inner shell will give the least possible resistance to the passage of smoke and gas into the outer shell and at the same time present the greatest possible surface for the absorption of heat. I also wish to call attention to the cold-air pipe extending to the floor, so as to take up the coldest air and so as to create the greatest possible draft. This is a matter of great importance over placing the inlet-opening directly in the bottom 6 of the outer shell.
I claim- The improved hot-air-circulating drum, comprising the outer cylindrical shell; a nipple, 8, located at the center of the lower end of said shell and projecting a distance below the same, to be inserted in a stove-opening; a nipple, 9, projecting upwardly from the upper end of said shell and located laterally of the axis of said shell; the funnel-shaped inner shell, 12, mounted within said cylindrical shell centrally of the same; a nipple, 16, located laterally of the axis of said cylindrical shell at the upper end thereof, and forming a passage from the said funnel-shaped inner shell upwardly through the upper end of said cylindrical shell; a nipple, 15, extending in a horizontal direction and forming a passage through the wall of the said cylindrical shell into the said funnel-shaped shell at the upper end of the latter; an elbow, 17 secured to the outer face of the said cylindrical shell, and
MILTON O. GREEN.
