SI DE-WALL VENTI LATO R.
SPECIFICATION formingpart of Letters Patent No. 235,303, dated December '7, 1880.
(No model.)
To all whom it may concern.
Be it known that I, WILLARD E. SMITH, of the city of Brooklyn, State of New York, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.
My invention has reference to that class of ventilators known as side wall ventilators, used on boats and cars, principally on the latter, to induce an outward draft through the ventilator from within the body of the moving car or boat.
It is my object to produce an entirely effective ventilator of this class which at the same time shall more effectually exclude rain and cinders than others heretofore made. 1 make use for this purpose of deflecting-plates, in combination with an outer air channel or passage extending from end to end of the ventilator, and provided on the side next the deflecting-plates with a central opening, into which the air-currents are directed by the deflectors. The deflecting-plates areset at such an angle as to insure this result, and the outer longitudinal air passage or channel has an area sufficient to receive the air passing to it from the deflectors.
In the accompanying drawings I have represented a ventilator embodying myimprovements.
Figure l is a horizontal section, and Fig. 2 is a perspective view of the same.
The body of the deflector is formed of the outer plate, A, top and bottom plates, B O, and flange or rim D, by which it is attached to the side wall of the car, so as to cover or communicate with the opening formed through the same, in the usual way.
The outer plate, A, is preferably fiat and without bend from end to end. It forms the outer wall of the longitudinal air passage or channel a, which has been hereinbefore referred to. The other vertical wall of said airchannel is shown at E, provided with a central opening, I), through which the air which passes from between the deflectors enters said passage.
Between the wall E and that face of the ventilator which is applied to the car are defleeting-plates 0, arranged as shown, each plate being set at such an angle that, if prolonged, it would enter the channel (I, through b, as indicated by the dotted lines in Fig. 1. These deflecting-plates are placed on each side of the opening in the deflector which leads into the car.
The number of plates may vary as required. Ihave shown three on each side; but their number may be increased or decreased at pleasure, although I prefer to use several on each side, in order to afford additional safeguard against entranceinto the car of cinders or rain.
When the car is in motion the air which rushes through between the deflectors at the front end of the ventilator will be deflected into the straight outer channel, a, carrying with it into said channel such rain, cinders, &c., as may beat in, and effectually preventing the same from being deposited in the ventilator at a joint between the deflecting-plates, whence they might be conveyed by eddying currents or irregularities of draft into the body of the car. I thus remove an objectionable feature in ventilators of this class, while at the same time the ventilator itself is so constructed as to prevent, to a great extent, the cross currents or eddies which so often arise in ventilators as hitherto made.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
In a side-wall ventilator, the combination, with inclined deflecting-plates, of an outer longitudinal air passage or channel extending from end to end of the ventilator, and separated from the deflecting-plates by a wall provided with a central opening, through which the air-currents are directed by the deflectingplates into said channel, substantially as hereinbefore set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 23d day of October, 1879.
