HEATING AND VENTILATING BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 362,116, dated May 3,1887.

Application filed August 14, 1886. Serial No. 210,944. (No model.)

To aZZ whom it may concern:

Be it known that I, Mronnnr. RUMBAUGH, of Cincinnati,county of Hamilton,and State of Ohio, have madea new and useful invention in Heating and Ventilating Buildings, of which the following is a specification.

The object of my invention is to provide a convenient and economical means of heating and ventilating buildings. For this purpose I construct the building with vertical fines extending in the space between the walls and communicating at their upper and lower ends with the external air. These fines I divide by a transverse partition or cut-off plate at or near the floor-level of the room with which it is designed to communicate. I also construct horizontal fines between the joists of the floor, one for each of the said vertical fines and communicating with its corresponding vertical flue below the transverse partition thereof. These horizontal fines I provide with an orifice opening into an airtrunlqwhich passes around or in close contact with the heater within the room to be heated and ventilated and opens at or near its top into said room. I further form an aperture through the wall of the room into the upper division of the vertical fine, in which upper division. I place the smoke-stack or escape-flue for the products of combustion, introducing these products of combustioninto it through a suitable pipe. Either or all of the fines, or the apertures communicating with them, may be provided with any convenient register or valve for regulating the draft. My plan contemplates avertical fine and a corresponding horizontal fiue for each room to be ventilated. These fines occupy no space otherwise available,and,being completelyhidden,do not disfigure the building, either externally or internally, while they add little to the expense of construction. They afford aeompletely independent means of ventilation for each room. The fresh air, being brought first into contact with the heater,distributes its heat throughout the room, and pure air is thus obtained at the desired temperature and without the inconvenience of cold drafts.

In the drawings, Figure 1 is a face view of portion of the inner wall of a building having the lathing and plastering removed in places Fig. 6 is a modification of Fig. 2, having also a portion of the j acket of the heater broken away. Fig. 7 V is a horizontal cross-section taken through z a, Fig. 5, showing, however, the smoke-pipe in perspective.

A A represent vertical fines between the walls of the building B 0, having partitions a.

D D represent horizontal fiues communicating with the vertical fines, respectively, and opening at 1) into a trunk or drum or jacket,-i', inclosing the wall of the heater G, or a portion thereof. This drum is opened at the top, so as to allow the air, after passing in contact with the heater,to escape into the room. If desired, a register may be provided at this point to regulate the current of infiowing air.

H H represent the several fioorsof the building; at d, thejoists of the floor; K, the apertures from the room into the upper division of the vertical fines; E the smoke-stack, entered by the smoke-pipe F through suitable orifice, f. By providing an orifice, Z, to the smoke-stack opposite the aperture K, and a removable cap for such orifice, I am able to readily remove the soot from the smoke-stack. The external air reaches the lower end of the vertical fine through apertures M, which may extend in either direction, and either communicate with a common inlet-pipe or directly with the outside of the building. The upper end of the flue may communicate with the outer air through the chimney, or in any other convenient place.

In the modified form of construction shown in Figs. 5, 6, and 7 I dispense with the interior smoke-stack and separate the smoke-fine N from the airfiue by any suitable partition, g. The heat from the heater causes the air in the drum to ascend,thus creating a suction to draw in the external air whenever the room is to be warmed for use. At the same time the smoke flue serves to heat the air in the vertical air-flue above the aperture K, causing it to rise and I creating a suction to draw off the impure air from the room. The course of the air from the flue is represented by arrows.

It will be seen that I have thus an indepen dent and economical means of ventilation for each room without occupying space that might otherwise be available for other purposcs,while the heater, without the addition of other mechanical means of any kind, furnishes the necessary propulsion to both drawin the fresh air and exhaust the impure air.

While I have shown a jacket or drum as a convenient method of bringing the cold air in contact with the stove before its discharge into the room, I do not mean to confine my invention to the particular construction of this passage or chamber. The inflowing air may be carried by a pipe through the stove or other heater, or brought into contact with it in any other suitable manner so as to be heated before being discharged into the room.

Various forms of heater may be used. If a steam-heater is employed, the steam-pipe may be carried from story to story. through the escape air-flue, or in such proximity with it as to afford the desired propulsion for the air in the flue, in lieu of the smoke-stack or parallelfiue.

The fines for ventilating the second floor have the transverse partitions or cut-off plates located therein at or near the level of this floor. The same is true of each successive floor, the arrangement being the same in respect to each fioor,asshown and described more particularly with reference to the ground fioor. These flues can be varied in shape and arrangement,

according to convenience or to suit the taste of the architect..

I claim- 1. In combination with the wall of a room, a flue having a transverse partition near the floor-level, a communication with the outer air below the partition, and another communication with the outer air at its upper end, a flue extending between the joists of the floor from the lower division of the first-mentioned flue and communicating with a pipe, whereby the inflowing air is brought in contact with the heater and thence discharged into the room, an aperture from the room into the up per division of the first-mentioned flue, and the pipe through which the products of combustion are carried off from said heater, extending,in contact with said flue,between said aperture and the discharge-opening, substantially as herein described.

2. The herein-described means of ventilating a building, consisting of a vertical fine for each room, extending between the walls, having communication with the external air at their upper and lower ends, and having a transverse partition near the floorlevel of the room with which each communicates, horizontal fines extending between the floor-joists, each communicating with its respective vertical flue below its partition and with the surface of the heater of the room, and thence with the room itself, and an aperture leading from said room into the foul-air flue above the transverse division-plate, substantially as herein set forth.

MICHAEL RUMBAUGH.
