Application tiled April 29, 1885.

To all whom it may cmwern:4

. Improvements in Heater-Drums and Ventilalators; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specication.

This invention relates to certain new and useful improvements in stove-pipe drums and ventilators; and the invention consists in the peculiar construction and arrangement of an outer and inner drum, between which is located a spiral flue, while through the center of the inner drum is arranged a direct-draft smoke-flue; in the peculiar arrangement of air pipes and passages, and in the combinations of the various parts, all as more fully hereinafter set forth.

In the accompanying drawings,which form a part of this specification, and in which my improved d-rum is shown in central vertical sec` tion and mounted upon a stove, A represents an outer shell or drum provided with closed ends, which are in turn provided with smoke inlet and exit pipes B and .0, designed to be inserted in the line of stove-piping at the desired point, as in the ordinary manner.

D represents the inner drum, which is provided with the heads Eand F. lIhrough this drum is formed the flue G, in line with the inlet and exit pipes B and O, while the upper end of such fiue G is provided with a damper, H, adapted to be operated by a damper-handle, I, from the outside of the shell A. At or near the upper end of the drum D, and connecting with the annular space between it and the iiue G, is an airiiue, J, which passes through the wall of the outer drum to discharge the heated air into the room, or to a line of piping to deliver the heat to a room above. At the lower end of the inner drum, D, and. communicating therewith, is an airinlet pipe, K,which passes out through the wall of the shell A, and thence to the outer air, so' as to deliver fresh air to the device. Surrounding this air-pipe K is a larger pipe, L, which communicates with the drum A, while its opposite end extends to the door and is provided with a series of holes, a, to admit of Serial No.163,806. (No model.)

air being drawn into the pipe L from the door of the room. In the annular space between the inner and outer drums, and about the length of the inner drum, I rigidly secure a spiral flue-strip, M, in any convenient manner, thus converting such annular space into a spiral flue, N.

In practice when the device is mounted upon a stove, as-shown, when a direct draft is desired, as in starting a fire, the damper H is opened, allowing the smoke and products of combustion to pass directly to the exit-pipe through the flue G, and thence to the chimney. By turning the damperH so as to close the upper end'of the flue G the products of combustion are compelled to find exit by passing up the spiral flue N, and in its passage throwing off a portion of its heat by radiation froml the outer drum, A, while it also heats the air contained in the inner drum, causing it to discharge the heated air into the compartment through the pipe J. rlhis creates a draft through the pipe K from the outside, thereby furnishing the room continuously with a fresh supply of heated air from the outside, forcing the cold air to thc oor,where y it is drawn into the pipe L and discharged through the drum A with the products of combustion.

The heads E and F of the inner drum I prefer to make of cast-iron with flanges upon which to secure the ends of the drum and iiue G.

What I claim as'my invention is- 1. In a combined heater-drum and ventilator, the combnation,with the drums A Dand flue G, arranged Within the drum D, of the due L, communicating with the drum A, and the flue K, arranged within the line L and communicating with the drum D, substantially in the manner and for the purposes specified.

2. In a combined heater-drum and Ventilator, thecombination of the drums AD, smokeues B, O, and G, air-dues J, K, and L, damp.- erH,and spiral'iiue-strip lVI,when constructed, arranged, and operating substantiallyintlle manner and for the purposes specffl- JQHN QYLTRINGER.
