CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 301,904, dated'J'uly 15, 1884.

' Application filed March 15, 1884. (No model.) 7

thereon.

This invention has relation to chimneys, and has for its object to provide devices for improving the draft of chimneys generally, and especially thosev located below adjacent elevations'such as higherhouses,hills, &c.as will hereinafter more fully appear. I

The invention consists, essentially, in the peculiar construction of the inner or wind flue, and in the combination thereof with the outer shell or flue and the chimney, and in other im provements, as will be described and claimed.

Inthe drawings, Figure 1 is a vertical section of a chimney and my attachment thereto,

wind-flue, the conical air-chamber or heater being broken away in section.

The chimney tube or extension A is provided with a rib or flange, a, which rests on the chimney B, and is thereby'supported. The outer shell or flue, O, is made larger than the tube A, and is secured at its lower end to said tube by means of plates 0, extended between the two tubes, and so arranged as to hold the bottom of tube 0 above the chimney, and pro-- vide an opening to admit the wind deflected upward by the roof. I provide this flue at its lower end with a lateral flange, D, inclined downwardly, so as to catch the wind as it rises from the roof. Eyes or loops (1 are secured on the inner side of the outer flue, near its upper end, to receive the hooks on the wind-flue E. This wind-flue E is open at its upper end,

which is projected slightly above the outer.-

flue, and it has on such end a laterally-projected convex flange, e, or curved upward and outward, so as to deflect the smoke rising in the outer flue outward, so that it will not be drawn into the wind-flue. This flange also serves to prevent the descending wind from entering the outer flue, and directs it into the windflue. This wind-flue is provided with hooks F, adapted to be projected through eyes d and support the wind-flue in place, so that it may be readily removed to remove the accumulated soot, or for any other purpose desired. A dish-shaped or concave bottom, G, is secured on the lower end of the wind-flue by cornerplates 9, so as to provide a space on all sides through which the air may pass below the end of the wind-flue. The edges of this bottom extend up on opposite sides of and slightly above the lower end of the windflue, as shown in Fig. 1. V This bottom, being concave, directs the wind to its sides or edges, and thence into the outer or smoke flue, when it is carried up and out the upper end thereof, as indicated. I prefer to form this concave bottom with a depending conical air-chamber, H, having its lower end or apex extended into the chimney.

This chamber becoming heated serves to produce a suction and draw up the smoke, as will be readily understood. The conical form of this heater serves to condense the smoke as it rises, and thereby increases the intensity of the draft.

' The operation is simple, and will be readily understood. The wind blowing on the roof is blown into the outer flue or easing, under the flange D thereof, and the wind coming from above, instead of entering the chimney and causing it to smoke, blows down intothe wind-flue, and striking the concave bottom is directed out on opposite sides into the outer flue, and passes upward with a strong force,

producing a powerful draft. The concave.

bottom prevents the wind from being stopped in its downward passage, and directs it easily and quickly out'at the side as desired.

By my invention the necessity of building high chimneys is obviated, resulting in a great saving, as the improvement may be made of any suitable sheet metal at a small cost, as will be readily understood. I

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
