'VENTILATOR The Schedule referred t in these Lettera Patent and making part of the same.

To all whom 'it may concerne.

Beit known that I, WILLIAM F. TnoMs, of New York city, in the county and State of New York, have invented a new and useful Improvement in Ventilator;

and I do hereby declare that the following isa full,

clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

Figure l is a detail-vertical section of a portion of my improved ventilator.

Figure 2 is a detail sectional view of the entire apparatus. V

Figure 3 is a detail top view of a portion of the same. l i

Similar letters of reference indicate corresponding parts. I

My invention has forits object to furnish a simple,

convenient, and effective apparatus for Ventilating dwellings, oflices, churches, halls, and other buildings, and which shall be so constructed and arranged that it may be so adjusted as to introduce into the room warm air in winter, and cool air in summer; and

It consists in the -construction andcombination vof various parts, as hereinafter more fully described A is a short vertical `pipe,`which is set in a square of a window-sash, or in the wall of a room or building.

vJi/'ith the outer side of the pipe A is connected an upwardly-inclined pipe, B, the outer end of which communicates freely with the outer air.

With the inner side of the pipe A is connected a short pipe, O, projecting inward at right angles to the i said pipe A.

The pipe G should be so arranged that its lower side may be about opposite the centre of the opening into the pipe B, as shown in figs. l and 2.

Upon the end of the pipe (l is formed an elbow, D, projecting upward at right angles to the pipe C.

'lo the yupper end of the elbow D is attached one end of the pipe E, which extends along the ceiling of the room, and 'is made broad and thin, to expose the cold air entering the room throughpsaid pipe, when in a thin sheet, to the heated upper `stratum of air in said room, so that the air may be warmed before being discharged into the room.

F is a valve, extending along the lower side of the pipe G, and made of such a' length that when pushed inward its forward end may reach about to the centre ofthe pipe A. Y

a is a small door, formed in the forward side of the lower part of the vpipe A, below the pipe C. rlhe door a may be opened to allow the cold air to escape directly into the room for summer ventilation, ora charcoal stove may be placed in the lower part of the pipe A, to produce any upward draught through the pipe B,

to draw ofi' the warm air from the upper part of the room.

rLhe. apparatus A BG D E F may be used alone or in connectionvwith the part of the apparatus hereinafter described,

G is a pipe, which is placed in a window-sash, or in the wall in the lower part of the l'oom, and which communicates with the outer air through the upwardlyinclined pipe H.

With the lower part of the pipe G is connected the end of a pipe, I, so arranged that the upper side of the said pipe I may be directly opposite thc middle part of the end or orifice of the pipe H.

'J is a valve, sliding along the upper side of the pipe I, and made of such a length that when pushed in its forward end may be at the centre of the pipe G.

In the end of the pipe I is formed a small door, fi, as shown in lig'. 2. i

With the lower side of the end of the pipe I is connected the upper end of the downwardly-projecting pipe K, which is made with au opening in its lower part for the passage of air, with one or more gratings, k1, to receive ice to cool the air before it enters .the room, and with one or more small doors, k2, for convenience in puttingin the ice.

Beneath the lower end of the pipe G is formed a recess, L, in which may be placed a small charcoal stove, to promote the circulation of air through the apparatus when required.

The two parts of the apparatus may be used scparately or in connection, as may be desired, but the best results will be obtained when .they are used in connection.

When they are used in connection, they may beplaced, the one above the other, upon the same Aside of the room, as indicated in fig. 2; or thevmay be placed, the one in one part of the room and the other in an`- other part, as may be desired or convenient.

For winter ventilatiomthe apparatus is arranged as shown iu iig. 2, the cold air passing in through the pipes B A OD E, and being warmed in the pipe E before it enters the room,the shoulder or elbow D preventing the escape of the warn1 air through said pipes.

f lhe impure air passes out through the pipes K I G II, the circulation being increased, when necessary, by applying heat to the lower end of the pipe G, as hereinbefore described.

For summer ventilation, the valve F is pushed in or closed,`and the valveJ is drawn out or opened. The outer air enters through the pipes H G I K,

.being cooled by ice placed in the pipe K, when necessary. lThe warm air passes out through the pipes It D A B, the circulation being increased, when desired, by heat applied to the lower part of the pipe A, as hereiubefore described. l

Having thus described my invention,

I claim as new, and desire to secure by Letters Patcnt- 1. The combination and arrangement of the pipes B A C 1)l E and valve F, with each other, when used alone or in connection with the pipes H G I K, said parts'B A C D E F being constructed and operating substantially as herein shown and described, and for the purpose set forth.

2. The combination of th pipes H G I K and valve i J, with each other, Whether used alone or in connection with the pipes B A G D E, said parts H G I K J being constructed and operating substantially as herein shown and described, and for the purpose set forth.

3. The combination* of ancharcoal stove or other heater with th'pipes A and G, or either of them, substantially as herein shown and described7 and for the purpose set for th.

4. The combination of one or more gratings, k1, with the pipe K of the apparatus G H I J K, substantially as herein shown and described, and for the purpose set forth.

The above specification of' my invention signed by me, this `6th.day of October, 1869. p
