PATRICK PITTMAN CARROLL, OF SEATTLE, WASHINGTON.
CAR-VENTILATOR.
Specification of Letters Patent.
Patented Feh. 19, 1907.
Application filed February 23,1904, Serial No. 194,698.
To all whom it may concern:
Be it known that I, PATRICK PITTMAN CAR- ROLL, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Oar-Ventilators, of which the following is a specification.
My invention relates to means for ventilating sleeping-cars, parlor-cars, and other passenger-cars; and the objects of the same are to provide means for giving a thorough ventilation to the interior of the car and to provide means for excluding cinders, dust, and other flying particles and at the same time to purify the air led into the car.
Another object is to provide means for moistening the air at the point at which it enters the ventilator in order that the air may be purified and cooled ,if necessary, and thus prevent small particles from passing into the car.
I attain the objects referred to by means of the construction illustrated in the accompanying drawings, which form a part of this specification, and in Which Figure 1 is a side view of a parlor or sleeping car provided with means for ventilation constructed in accordance with my invention. Fig. 2 is aperspective view of a short section of myWater-tank and ventilator-tube. Fig. 3 is a detail view, in longitudinal crosssection, of the ventilator-tube and atrunkopening.
Referring novv to Figs. 1 and 2, the numeral 1 designates a parlor or sleeping car of the ordinary or any suitable construction.
Upon the roof of the car a tubular ventilating-pipe 2' is secured. To deflect the dust and cinders, there is provided at the ends of this pipe a tapered and pointed wire-gauze shield or inlet 3, which screen projects in advance of the end of the tube 2. Within the tube, at a point near the inlet '3, a fine wiregauze screen 4 is secured. The tube 2 extends nearly the entire length of the car, and at suitable intervals trunk-openings 5 are provided which lead to the interior of the car, and these openings may be provided with sliding doors or similar closures 6', running on rails 7 and supported also on the flanges or lips 13 at the lower ends of the trunks. Superposed' upon the ventilating-tube 2 is a water-tank 6, said water-tank extending nearly the full length of the car and overhanging the ends of the ventilating-tube. At the ends of the Water-tank a drip-cock 7 is provided, which is designed to permit water to drip from the tank to the surface of the inlet-screens 3 in order that the air led into the interior of the car may be moistened, purified, or cooled in the summer and at the same time to prevent dry particles, like dust and cinders, from floating into the interior of the car. By these means when taken in connection With the ventilator-tube at the top of the car a thorough circulation may be maintained and regulated. If it is desired to feed warm air into the car instead of cold, a system of steam-pipes 2 may be led through the ventilator-tube2 and into the car through the screened openings 5 in a manner which will be readily understood.
From the foregoing it will be obvious that pure moistened air in the required quantity may be fed to the interior of the car through the ventilator-tube 2, and that cinders and flying particles will be excluded from the interior of the car, and that a thorough circulation and ventilation is attained by means of the construction shown.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
The combination with a car, of a ventilator-tube extending along the roof thereof, tapered screens adapted to deflect the dust and cinders located at the opposite open ends of the tube and projecting in advance thereof, said screens being located exteriorly of the car, finer screens located within the tube near each end thereof, a water-tank located above the ventilator-tube, means carried by the tank for moistening the first-mentioned screens, trunk-openings leading from the tube to the interior of the car, and means for closing the trunloopenings.
In testimony whereof I have signed my name to this specification in presence of two witnesses.
PATRICK PITTMAN CARROLL.
