. Lette/rs Patent No. 84,608,l lated Dccembfrtl, 1868.

,IMPROVEMENT IN vnNTmI-I'QN.

A The Schedule referred to in these Letters Patent and making part of tnv una.

Be it -known that I, GEORGE W. BLAKE, of the city,

county, and State of N ew York, have invented a new right angles to each other, of a building, in part, with my improvement applied thereto.

My invention consists in the arrangement of radiators within the fines, which serve to conduct the heat from awarming-apparatus to the several rooms or stories of a building, whereby a more eqnable distribution of the heat through the several stories is obtained, and the often inconvenient and unsightly disposition of the radiators within the rooms themselves is avoided. Said invention also embraces, in combination with such an arrangement of radiators, a valve to the fresh-air shaft, at or near its base, and arranged to admit a downward current through said shaft, but to automatically close against an upward one or rush of air down the roomiiues to and up the shaft, by the heating of the air therein, as hereinafter referred to.

Referring to the accompanying drawing, A, B, and C represent first, second, and third-door rooms of a building, and D, a cellar or basement thereto, in which may be heated the boiler or furnace for warming and Ventilating the building, but which it will here suiiice to refer to as a steam-boiler, though a hot-air heater may, if desired, be substituted.

E is the shaft for conveying cold air from above -to the basement D, vor chamber located therein, and cennecting with fines F G H, which communicate, respect ively, with the several rooms A, B, and C, through registers I J K, arranged, for instance, on one side of fire-places a b o, supposing the rooms to be provided with such. Steam is conveyed from the boiler to a box or boxes, L, located' in or near the bottoms of the dues F G H, and connecting or communicating with radiators M N O, of sheet, tubular, or'other form, arranged within the lues F G H.

By this disposition of the radiators, that is within the ues themselves, a more equable distribution of heat to the several rooms'or stories is obtained, inasmuch as the cold or fresh air supplied by the shaft E, and which is warmed or heated by its passage round or through the radiators, is not concentrated in a single flue, and from thence drawn off or distributed to or within the ydifferent rooms by the registers located therein, which system of warming causes the greatest heat to collect and be distributed-in the upper rooms, but by each,say, of the separate 'roomaues F G H, having a radiator within it, the fresh air supplied by the shaft E is equally, or thereabouts, and separately heated within the room-dues FG H,inrits passage to or up the latter, each room thus drawing an independent supply of heated air, through its register, from its respective flue, separately heated, as described, in steadfof from a'ilue common to all. Furthermore, by the arrangement 'of the radiators within the roomiiues, while each room may be said to have a separate radiator, the same, by being disposed Within the room.- iue, presents no unsightly appearance, but is concealed, and is out of the way, thereby giving more room in the apartment. Y

P is the usual esoape'or foul-air shaft, common to all the rooms, and communicating with the several apartments, by register-SQ 1t S; Valso in which a radiator, T,

may be arranged, to establish or quicken the upward current of. air entering from the basement.

To prevent an upward current being established through the cold or fresh-air shaft E, by rush of air from or down the room-dues F G H, on opening the registers I J K, which is apt to occur after the registers have been long closed, and the lower portion of the shaft E become unduly heated by the radiators, I provide said shaft E, at or near its base, with, or otherwise equivalently arrange, a valve, V, hung to operate automatically, so as to exclude an upward current through vthe shaft E, but freely admitting of 'a downward one therethrough, as and for the purpose hereiubefore set forth.

What is here claimed, and desired to be secured by Letters Patent, is-

1. The arrangement of radiators within the room-v flues,'substantially as and for the purpose or purposes herein set forth.

2. The combination, with the fresh-air shaft, and radiators'arranged within the room-dues, as described, of a valve, operating automatically, to prevent an upward current being established through said shaft, but freely admitting of a doi'mwardone through the same, essen- 'tially as specified.
