MODE 0F VENTILATING AND SUPPLYIN'G HOUSES, 860., WITH WARM OR COOL AIR.

Specification of Letters Patent No. 67, dated October 24, 1836.

To all whom it may concern:

Be it known that We, ROBERT MAYo, M. D., and ROBERT MILLS, architect, both of the city of Washington, in the District of Columbia, have invented new and useful Improvements in the Mode of Ventilating and Supplying Houses and Apartments with Warm or Cool Air, and that the following is a full and exact description of the said improvements as invented by us.

This invention consists of certain combinations of inventions, or improvements already in use applied to the purposes of ventilating, and supplying houses or apartments with warm, or cool air, viz: 1. For ventilating and supplying apartments with rarefied, or warm air, the undersigned ROB- ERT MAYo and ROBERT MILLS, combine or connect the fiues of suitable dimensions constructed in the masonry of the wall, or chimney as described in the said ROBERT MAYos patent for supplying atmospheric air to fire places, or grates by pneumatic pressure, dated the 9th of September, 1835, with the hot air chamber, or reverberating space around the fire chamber of the grate, or fire place of the apartment as described in the said ROBERT MAYos patent for a reverberating grate dated the 1st of November, 1826, or otherwise in use so that the air to be heated in said hot air chamber, or reverberating space shall be supplied from a lower medium by atmospheric pressure, or draft through the said fiues constructed in the masonry as aforesaid and be conveyed from said hot air chamber into the apartment in the manner described in the said patent of the 1st of November 1826, or'otherwise in use. Or 2d the said MAYO and MILLS also combine and connect the lower extremity of said lines with the hot the chimney or into the outer air. The said MAYO, and MILLs also connect the said fur-' at their outer extremities, and to be sur-' mounted, or not with open movable funnels to receive and supply the draft of air from any direction. Or 3,.1when the object isto ventilate, and supply the apartment with cool air, orair of reduced temperature, the said MAYo, and MILLS dispense with the furnace as just described so that the draft through the fines may be derived from the open air, or atmosphere to be circulated in the apartment, without the heating process as just described of the, warm air from the warm air chamber of the furnace, or they simply dispense with the fire in the furnace, or in the fire place in the apartment for the time being, and substitute therefor a body of ice to be so disposed of in connection with the draft of air throughthetube, and fines as to reduce its temperature, the whole of said air drafts to be governed by suitable valves in the fines, or tubes with this system of improvements in the construction of chimneys, fire places, flues, &c.

We propose to connect, or add a series of suitable apertures secured by iron doors in the garret, or' attic rooms communicating with each smoke flue by which the same .several means, and devices herein above enumerated and referred to for the purposes of ventilating and sup-plying houses and apartments with warm, or cool air.
