/ AND WILLIAMF. WHITEHOUSE, OF SAME PLACE.

Letters Patent No. 90,976, dated June 8. 1869.

VENTILATO.

The Schedule referred to in these Letters Patent: and making part; of the same.

The nature of my invention consists in providing an air-chamber, to be located in the building, or any apartment thereof, or in thehold of a vessel, or in any compartment requiring ventilation, at any convenient point, as hereinafter set forth, the air-chamber to be 'connected with each apartment or compartment to be ventilated by auv air-flue or flues, and by an exhaustue with a furnace or other heating-apparatus, or with a chimney or conduit for steam, heat,

or smoke, or .with a flue with coils of steam-pipe' therein, by which the air maybe heated, rarefied, and exhausted from the air-chamber, and its connection or I connections.

To enable others skilled inthe art to make and use l my invention, I will proceed to describe its construction and mode of operation.

I construct an air-chamber as shown at A, in the accompanyingdrawings, the size of which would vary according to the number Aand size of the chambers, apartments, or compartments to be ventilated. In Figure l itis shown as sunk beneath the floor of the cellar or basement, and left open for reference. It is a closed chamber its materialstxmay be Wood, metal, brick, or-stone; itmay be located at any `convenient point below where the heat is applied to the exhaustiiue H, butin case it be dilicult or inexpedient thus to locate it, itmay be placed at any convenient point,

vprovided that the exhaust-Hue at some point descends belowthe level at which heat is applied to operate the exhaust-flue, as shown in Figure 7.

This air-chamber lis connected with each room, apart` ment, or compartment to be ventilated, byone or more air-fines F F, and registers E E, in number and position as may be required, (see Figures l and 2,) the air-dues to enter the airchamber A in or-near the bottom.

Then I construct an exhaust-due, H, from the said air-chamber, in the topor at the side or .end of the same, near the top, or as near the top as may be necessary to effect the object desired, viz, the exhaust of the foul air, to the air-chamber B of the furnace D, -(see fig. 2,) thence through the air-pipe C to the smokeflue N, (see Figure 4;) and in order to give force and direction to the current of air, I conduct the smokepipe J up the chimney or due, from seven to ten feet, or so far as may he required to properly utilize the 4heat; then, and not till then, the air land smoke commingle, and a draught is given tothe fire, and force to the whole current, until its escape into the atmosphere above; or I carry the exhaust-flue H direct to the chimney or other conduit for the escape of heat and smoke, (see Figure 6,) or to a special conduit for that purpose, to or within which heat is applied by steam-coils or otherwise; or, if it be more convenient, instead of extending the smoke-pipe J up the chimney or flue, I carry the exhaust-due H up the chimney or flueso far as may be necessary to` create suicient draught in the exhaust-due. (See Figure 9.)

In large buildings or compartments, and where no fires are in constant use, I employ a furnace, D, to produce the heat required,` (see fig. 1,) but where opportunity offers, I use the waste heat from steami boilers, hot-air furnaces, or kitchen-ranges, and stoves, as the case may be, to warm and rarefy the air lof the chimney, due, or conduit, and keep in constant circulation an ascending current of air, and thus exhaust the foul air from the rooms, apartments, or compartments.

The air-pipe O, from the furnace D, (see fig. 4,) must be of suiicient capacity that the atmospheric pressure shall at all times be greater than the force of heat thrown off by the pipe J, that there may be a free circulation.

In case of a single apartment to bc ventilated, I deem it sufiicient to put a register, E, in the chimney c1' ilue, (see Figure 5,) and create a draughtin the chimney or due above that' point by extending the smoke-pipe J up the chimney .or ue, or by any of the means above set forth. l

p I- prefer to take the supply of atmospheric or external air from the top of a building by iiues and registers in thewalls, or byother suitable means, (see Figure 3,) the said ues K and registers I being -in number and position as deemed desirable, or from wherever the external air can be obtained to the best advantage for the purposes required or the objects intended. I do not consider it necessary to this system of ventilation to use the air-dues Ii (see fig. 3) under all circumstances, as'sufcient'external air may be received A,by ordinary means, onfrom a furnace when in use.

There is no difculty in drawing cold air down the flues, provided the lines are kept cold.

In case the air that passes through the exhaustiiues is so impure that it would be objectionable that the same should mingle in this condition with the external air, I employ a deodorizer or disinfectant to remove the impurities.

Any deodorizer may .be employed, and in any con venient manner may be applied to the foul air. 'Ubloride of lime may be used for this purpose, placed 0n` one or more wire-gauze trays placed in a small chamber, M, (see Figure 8,) connected with the exhaust-flue H, or in theexhaust-lue H, in ,such manner that the foulair may pass thoroughly through the same, and the impurities be removed.

The character of the disinfectant or deodorizer, and the manner of its application, would vary in accordance with the circumstances of individual cases, to some extent.

Having thus described my invention,

What I claim as new, and desire' to secure by Letters Patent, is-'- The combination of the airchamber A and the eX- haust-iiu H, and theapplicatiou thereto of a'deodorizer or disinfectant, iig. 8, in manner and. form sub-V stantially as shown and for the purposes as set forth.
