Letters Patent No. 101,168, dated March 22, 184'9.

To all whom it may conce/rn 33e it known that I, G. F'. SCHUL'ZE, ot' Janesville, in the county of Rock and .State of Wisconsin, have Ventilating Houses; and I do hereby declare the folwbich myiuvention appertains to make and use the same, reference being han rc the accompanying drawings forming part ot' this specification, in which the ligure is a vertical section ot' a room illustrating my Myinveution has for its object to more thoroughly heat dwelling and other houses, with greater economy of fuel than is now the case. .The primitive method oi heating was by an open While luxury has preserved the latter, economy has in progress by the common stove, which possesses the merit of radiating the heat from all sides. Without pensive medium for heatingpurposes.

The common stove radiates the heat but a shortdiately surrounding it, which, as it becomes heated, is rareed, andascends, and is followed by a current of cold air -from the floor ofthe room. This,viu its turn,

current of heat-ed air.V This current, however, is either limited to a narrow space immediately surrounding the stove, leaving the remote parts of the room cold and uncomfortable, or tilis the upper part of the room only,

the feet are surroundedby cold air, while the head and upper parts of' the body are exposed to' a dry, hot

temperature. y e These defects in the method of heating by the coni- Diienlties in conveying heated air from the furnace to the rooms caused the discovery that, to introduce a quantity ot heatedair into a room, the expulsion of the same quantity of the air already in the room be .G oi' the room.

The Schedule referred'to in `these Letters Patient-and making par: ofthe same,

ing became confounded, so that about the saine quam tity of partially cooled air is now withdrawn and wasted from a dwelling with i'ew occupants, not for ventila` tion, but in order t'o 'warm the same, as. is expelled from an eqnal-sized dwelling with rnanyocculmncs, when `the expiilsion may be justied on accountof ventilation.

This leads to the inquiry why -uuvitiatnd and only partially-cooled airis wasted. This partially-cooled air is much warmer than that outside the dwelling, and should be returned to the furnace and reheated, instead of heating the extreme cold air from without.

My invention, therefore, consists in producing a cir culation of heated air from a heater or furnace through the space to he heated, and, after being partially deprived of its caloric, back to the furnace to be reheated, the circulation being-continued indeiinitely, l

oruntil the air becomes vitinted, when it is'di schal-geil, and fresh air introduced.

lThe accompanying drawings represent the section of a dwellinghouse,.o` which` A is a room;

E, the floor;

C, the ceiling; y

D, the ceiling of a lo'werroom; and

E, an outside wall.

The i'ioor B is raised slightly above the lower cells ing l), to leave an air-space, F, between them, which communicates at one 'end with the room A, and at theother end with the liuc or chimney, G.

H is a hollow cylinder, open at 'both ends, placed vertically within the room A surrounding tile stove, furnace, or other heater I, and communicating at its lower end with the space F' beneath the floor.

J is a pipe connecting the interior of the cylinder with the outer air, or arranged in any suitable manner to supply cold airto the heater when desired.

It is provided with a valve or damper, a, by which V the supply oi' cold airis introduced or ont oii.

b'is also a valve or register in the due G, by which communication is opened or closed between the space F and said tine G. The smoke and products oi' combustion are discharged from the heater into the flue G hy means ol' the pipe K, in the usual. manner.

The operation is as follows:

As ting furnace l becomes heated, the air within the cylinder 'H is also heated, and rises against theceiling This is i'ollowed hya current of cold air from the space Fwhich, in its turn, also rises, and is'discliarged through the cylinder into the room rlhe heated air so escaping from the cylinderiuoves along the ceiling C to the outside wall E, and in its passage becomes cooled suliciently to cause it to de second "lo the Hoi-r, beneath which it is allowed to pass bach. agairnto' the heater, tol be rebeatetf and again discharged Vin'torthe room. -By this means n constant circulation is produced i-n the direction of the arrows, thoroughly warming all parts of .the room.

When the air becomes vitiated, the valve .a ln the supply-piped and the valve b in the ue G are opened, the formerto admit fresh air around' the heater, and

the latter to permitthe discharge of vitiated air from Suc-h.

the room Athrough the space F into the flue.` 'vitiated aii' is caused to ascend the ue, as shown by A,the arrows, being heated by'contact with thel pipe Kl yfrom the heater. These operations are continued alternately, as will be `1`feadily understood."r

It must, however, be borne in mind that the heating of the room is continued during the Ventilating process, so that it will not be subjectedl to sudden changes in temperature.

. 'Several rooms may be heated by my improved system from the same heater, which may-be placed in `any preferredv story of the dwelling. or other structure.

It is requisite,I however, to connect the room to be warmed with the top of the cylinder surrounding the heater. and the space below the floor with the bottom -heater within the rooni to be heated, for the purposeV 'of causing a constant circulation of heated air from the furnace through ithe space to be heated, and, utter being partially deprived of its caloric, back-tothe` l heater to be reheated, continuing indefinitely, in combination with a Ventilating process by which the vitiated air is expelled ii'om the room, or roomsyand cold air introduced, during the operation of warming, as herein shown and described. l u y G.
