IMPROVEMENT' IN VENTILATORS. Y

The Schedule refexred to in these Letters Patent and making part of the same.

To all whom t't-may concern: K l

Be it known that I, WILLIAM ENNIS, of the cityl and county of Philadelphia, in the State of Pennsylvania, have invented a new and improved Plan for Distributing Heat in Buildings; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyy ing drawing forming a part of this specification and tothe letters of reference marked thereon.

rlhe object of this invention is to provide a plan for the more thoroughly distributing heat and fresh air in a` building so'as to' warm and ventilate the same, and keep the supply both of heat and fresh air constantly under complete control, and thus regulate the temperature as may be desired; and likewise to use the heating apparatus for the purpose of drawing in fresh air and forcing out the foul or vitiated air, and to ventlate the room either from the upper part or the lower part, or from bothtop and bottom at the same time, as may be desired.

rlhe nature of this invention consists in a' peculiar and novel arrangement of the radiator' in connection with fines and valves or dampers, as willv be hereinafter more fully described and explained, for the purpose of obtaining a supply of pure air `from without the building; and either heatingpit by causing it tow come in contact with the heating surfaces of the radiator as it descends, so as to enter the room in a heated slate, or to conduct it into the room without being heated, for the purpose of-ventilating .the same; and in arranging the `valves or damper-s so that the supplyl both of hea-ted and of cold air be kept constantly under complete control; and also in arranging the radiator in such a manner that it wiliserve to draw the fresh air into the rooml and` drive out the foul or vitiated air or gases.

'lo enable others skilled in the art to make and use my invention, I will proceed more particularly to de scribe the same and its operation.

The figure represents a vertical section of a"portion of a building with my improved plan for distributing heat. v

A may represent the room to be warmed and ventilated. A

B is a radiator of ordinary construction, located and fixed at any convenient height within the flue or ventilating-shai't C, through which said radiator the air is caused Ior made to descend in contact with its heating surfaces before it enters the room.

Dis a flue communicating with the external atmosphere for the purpose of conducting fresh air into the room, either heated bycontact with the' radiator, as above described, or at the temperature of the external atmosphere or nearly so.'

This iine may be located or carried under the floor ot1 the room, and is provided with two valves or damper-s, a and b-the foriner for admitting fresh air into the ventilating-shaft C, within which it comes in contact with the radiator. and enters the room in a heat-ed state, and the latter foradmitting it into the room at or neary the temperature of the outside atmosphere.

E is an upright partition within the Ventilatingshaft, whichis carried ashort distance above the top of the radiator, and is for the purpose of'bringing the air admit-ted by the valve a into contact with the yupper portion of the radiator B, and causing it to `pass downward through the radiator in Contact with its heating surfaces, from whence itpasses from the lower portion of the same into the room in a heated condition.

is a valve or damper located in the ventilatingshaft above the top ot'v the partition E, and is for the purpose ci allowing the escape of carbonic-ac`1d gas and other heavy gases -which settle toward the floor, and which are forced up the Ventilating-shaft by the fresh air admitted through the valve b wheny the valve a is closed.

gis a valve or damper-for the purpose of allowing the heated and vitiated Aair-or lighter gases to pass fromthe room into the.ventilating-shaft.

In the drawing the radiator is shown located near the floor, but it may be placed at any convenient height in the fine, provided that the air to be heated is made toy descend through the same in contact with its heating surfaces.

It will be seen that, by myrimproved plan of distributing heat, the temperature and ventilation of a. room or a number of rooms can be adjusted and modified with the greatest nicety, by opening or closing the several valves-designed to produce thepdesired result.

When the room'is to be heated the valves f and b are closed and thevalve a is opened, by which means the air entering bythe ue D is made to pass downward through the radiator in contact with the heating surfaces before it enters the room. v

When it is desired to cool the air in the room as muchas possible and produce the greatest amount of circulation therein, the valve als. closed and theI valves4 b, f, and g are opened, by which means the heat is caused to pass up the ventilating-shaft, and the vitiated ait` and gases are forced through the valves f and g by the currents of fresh air admitted fromthe external atmosphere through the valve b.

Again, when it is desired to both heat the room andventilate it at the same time, the valves b and f are closed and/ the valves a and g are opened, so that fresh air is admitted through the valve a, andthe In combination with the shaft O and end-induction vitiated air and lighter gasesl escape by the valve g. tube D, the partition-wall E, located within the said It will also be seen that,by these means, the room shaft O, for the purpose of carrying the air downward lm, may be ventilated from both the top and the bottom upon the heating surfacesof the heater or radiator B, at the same time,'and, furthen'that the heating ap- 'and from4 thence into the room A, as herein shown paratus is utilized for the purposeI of forcing out the and described.

foul or vitiated air and gases by drawing in fresh air WILLIAM ENNIS. from the external atmosphere.

Having thus described my invention, 4 Witnesses:

What I claim as new, and desire to secure 4by Let- JOHN S. THORNTON, ters Patent of the United States, is WM. VENTZ.
