TO ALL WHOM IT MAY CNC'ERN':

Be it known that I, O. S. TREXLER, of Naperville, Du Page county,1llinois, have invented a new and useful Improvement in Ventil'ators; and fdo hereby declare that thefollowin'g is :t full, clear, and exact description thereof, which will enable others skilled in the artto make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates'to a new and improved method voi`-ventilating rooms in dwelling-houses, manufacturing establishments, and all buildings or apartments where vapor arises, nnd where it is desired to introduce fresh air of a temperature corresponding with that of the room which it is desired to ventilate; and theinventiou consists in inserting through the ceiling of such room or apartment a tube, having a cone-shaped sieve in its lower en'd, as represented inthe drawing. i

A is a tube, which extends from above through the ceiling into the apartment, and upward to' or near the roof of the building. Where it passes through the ceiling. or Hoor above it is secured by flanges, a,- as seen in the drawing, or in any other suitable manner. B is the cone-sieve., which is secured to the tube at its base, as seen. This tube may be made of perforated sheet metal, or of" wire cloth, as may be found most proper or convenient. C is a swing-door, which'is attached to the lower-end of the tube by a hinge. It may be adjustable so that the aperture or end ofthe tube may be closed, or partially closed, as may be` desired: D is a dange,`

which rests against the ceilingwhen the ventilator is in place, forming a nish'nround the rim,

Through the tube there will be an ascending current of foul, damp', and impure air, passing through the cone in ne jets, rendering rooms, previously damp and unwholesome, dry and healthy. The fresh air is introduced into the apartment in :my ordinary manner, but does not pass through the tube.

This arrangement isipeculiarly adapted to' apartments where water or other liquids are boiling, and from which condensation takes place, rendering the apartment damp :ind unhealthy.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The cone B, in combination with the tubeA, arranged substantially as shown ,and described for the purpose set forth. l I Y 2. The adjustable door C, in combination Awith the tube A andcone B, substantially as and for the purpose specified. i

Ther above specification of my invention signed by me this 13th day of'March, 1867.
