cut #1,705,491. The radiator 10 is enclosed This invention relates to apparatus for heating and ventilating buildings and more particularly to a window ventilator for deflecting and controlling a current of air admitted through an open or partly opened window to a heating radiator.

Among the objects of the invention are to provide a heating and ventilating apparatus whereby a uniform distribution of heat and air throughout a building may be obtained;

to enable any desired heating and ventilating effect to be obtained by suitable control of the circulation of air and of an apportionment of the air to difierent parts of the ventilating and heating appartus; to provide an apparatus whereby the heating capacity of radiators may be increased; and to provide a simple apparatus that may be easily installed in existing radiators to control the heating and distribution of air that may be admitted through an open or partly opene'd window.

A further object of the invention is to provide a method and apparatus of so directly ventilating currents in connection with a radiator as to intercept the transmission or escape of heat from the radiator to the adjacent wall of the building and thus avoid the overheating of the latter.

With these and other objects in view which will more fully appear from the following description, the invention comprises the apparatus described in the following spec1fication and claims. V

The various features of the invention are illustrated in the accompanying drawings, in which Fig. 1 is a vertical sectional view through a portion of a wall and window of a building, and a heating and ventilating apparatus embodyinga preferred form of the invention. Figs. 2, 3, 4 and 5 are similar vertical cross sections of modified forms of embodiments of the invention.

Referring more particularly to Fig. 1, the invention is shown as applied to a radiator 10 spaced a short distance from the inner surface of the wall 11 of a building and beneath a window 12. The radiator 10 may be of any suitable or standard type as, for,

example, the radiator shown in Murray Pat- Serial No. 360,331.

in a case of metal or other suitable material having a front wall 13 and Wall 14 which, with suitable side walls of any desired construction, form a chamber 15. The front wall 13 is extended for some distance above the upper end of the radiator 10 and is provided at its upper end with a grille or outlet opening 16. The wall 14 is inclined forwardly at 17 above the upper end of the radiator 10 to meet the wall 13 above the opening 16, thus deflecting heated air passing upwardly through the chamber 15 to the outlet opening 16 The upper end of the radiator is covered by a top plate or cover 18.

The wall 13 is also provided with an inlet opening 19 below the lower end of the radiaator 10 for the admission of air to the chamber 15 from the room to be heated. In addition to the air admitted through the lower inlet opening 19, a current of air may be supplied through the lower portion of the window 12 whenever the window sash is raised to the position indicated in dotted lines. The cold air admitted through the window 12 is deflected by means of a deflector plate 20 hinged at 21 on the top 18 to an inlet grille or opening 22 in the rear part of the top 18 and at approximatelythe level of the sill of the window 12. The draft of cold air deflected through the inlet 22 is received in a rear down-draft chamber 23 formed between the inner surface of the wall '11 and the wall 14 and side walls of the casing. The draft of cold air passes downwardly through the down-draft chamber 23 to an opening 24 in the wall 14 and thus enters the lower part of the radiator chamber 15 and, passing upwardly therethrough, is heated by the radiator and delivered through the outlet 16. The cold air thus delivered through the opening 24 and the air from the room or interior of the building entering through the inlet 19 may be. proportioned by means of a hinged damper 25 in thelower part of the chamber 15 in such a manner as'to apportion the drafts of air to attain any desired ventilating effect. Thus, by swinging the damper 25 forwardly the air admitted through the inlet 19 may be diminished or entirely shut off while by 2 r,ere;sss
