VENTILATING APPARATUS FOR BUILDINGS.

SPEGIFICATION formingpart of Letters Patent No. 613,431, dated November 1, 1899.

Application filed March 17, 1898.

T0 aZZ whom it may concern:

Beit known that I, REINHOLD STEINECKE, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Ventilating Apparatus for Buildings, of which the following is a specification.

This invention relates to an improved ventilating apparatus for buildings of all kinds, by which the air is drawn 0E and the building ventilated in a very effective manner with out the use of apparatus driven by power.

My apparatus is based on the principle that a column of air when heated at the upper end of a flue is set in motion in upward direction by the partial vacuum produced by the upward motion of the heated air.

My invention consists, therefore, of a ventilating apparatus which comprises a flue provided with an extension at the upper end, preferably located under the roof, a steamcoil or other source of heat in said extensionflue, and a hood extending over said flue adapted to prevent the back pressure of cold air on the upper end of the flue; and the invention consists, further, in certain details of construction and combinations of parts, as will be more fully described, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a vertical transverse section through a dwelling, showing my improved ventilating apparatus arrangedin connection therewith; and Fig. 2 is a vertical transverse section through a roof of a building having a hall, showing my improved ventilating apparatus for ventilating the hall.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a flue which is arranged either in the wall of the building or in the closets or at any other convenient point. The flue is provided with an extension A, which is preferably made of sheet metal and is located in the garret, below the roof of the building. A steam-coil O or other source of heat is arranged in the extension-flue A', so that the air in the same is heated, and thereby a current of air induced in the flue below the extension, whereby the rooms are ventilated in an efiective manner.

Serial No. 674,169. (No motel.)

The steain used in heating the coil in the extension-flue may be either from a boiler or other suitable source. The opposite end of the steam-pipe is conducted through the roof, so that the steam after use passes off into the atmosphere.

Above the ventilating extension-fines A is suspended a hood D, which is made of conical shape and provided with a bent-up circumference, as shown in the drawings. This head serves to protect the upper end of the extension-fines against the ingress of cold air, which would exert a back pressure on the rising current of heated air, and thereby prevent the proper functioning of the ventilating apparatus. The hot air is guided along the under side of the hood and the rim of the same, and thence in an upward direction, as shown by the arrows. Cold air is thereby deflected from the upper ends of the extension-fines, so that the same cannot enter into the flues and exert a counter-pressure on the rising column of heated air, which induces the current of air in the flues and produces the effective ventilating of the rooms of the building.

When the improved ventilating apparatus is arranged in an ordinary dwelling, the closets or other convenient space may be used for the flues, as shown in Fig. 1, while for ventilating halls the air may be sucked off through a flue A opening into the corner, as

shown in Fig. 2.

My improved ventilating system following advantages:

First: The ventilating appliances are arrangedjust under the roof, soas to be entirely out of sight.

' Second. As the extension-fines are heated and the entire warm air drawn intothe room the space on the roof is filled with warm air.

Third. The hood placed above the outlet of the extension-fines prevents the interference of the cold air with the regular discharge of the heated air, so that the effective and continuous ventilation of the-room to which the fines are connected is kept up.

Having thus described my invention, I

has the claim as new and desire to secure by Letters Patent-*- 1. The combination, with flues arranged in the walls or other part of a building, of an extension-flue located in and opening into the space below the roof, a steam-coil or other source of heat for heating the air in said extension-flue so as to produce an upward current of air in the flues, and a hood extending over the outlet of the extension-flue so as to prevent the counter-pressure of cold air on the same and keep up an uninterrupted ventilation, substantially as set forth.

2. The combination, with a flue or flues arranged in the walls or otherpoint of the building, said flues extending to a space below the roof, of an extension-flue arranged at the upper ends of said flues, a steam-coil arranged
