PATEN EDWIN H. WINOHELL, OF NEW YORK, N. Y.

IMPROVEMENT IN RAILROAD-CAR VENTiLATGRS.

Specification forming part of Letters Patent No. 119,809, (lated October 10, 1371.

To all whom it may concern:

Be it known that I, EDWIN H. WINOHELL, of the city, county, and State of New York, have invented new and useful Improvements in Railroad- Oar Ventilators and Dust-Deectors, and that the following is a full and exact description ofthe same, reference being had to the vdrawing accompanyin g and making' part of this my specification.

The nature of my invention consists, first, in a device and apparatus of a novel construction, placed upon and in the roof of the car, by which fresh air is introduced into the interior along the entire length of the car-body by means of a reversible conical funnel or hood, and distributed through adjustable registers or valves; and, secondly, in a peculiar construction of air-and-dustdeliectors or leaves on either side ofthe car-windows, and so constructed and arranged as to detlect outward and away from the windows the currents of air and dust produced in the rapid movement ofthe car, the deectors being' movable on their vert-ical axes so as to present a Hat surface to the air and dust, and facing its current in either direction of the car 5 and, also, so as when the detlectors are not operating' to fold or close with their outer edges at a very obtuse angle between the windows ot' the car, the two parts of my invention operating', when the windows of the car are open, to produce a current or currents ot' air outward through the windows, and thus together preserve the air pure and fresh within the car, and, by the outward current, to keep the exterior air and dust from entering in at the windows.

Figure l of the drawing represents a side elevation of the car, and of the Ventilating apparatus on the roof, and the deectors between the windows, the latter in position for deecting the air and dust. Fig. II represents the Ventilating apparatus in the roof by a vertical longitudinal section through the central axis of the apparatus. Fig. III represents a side elevation of the carbody, and the Ventilating apparatus, and of the deectors, the latter bein g in the position required when not operating and the windows closed. Fig. IV is a vertical or top view of window and delecting-leaves in position to act as detlectors. Fig'. Vis a vertical or top view of window and the leaves when not in operation as deflectors, but closed at an obtuse angle between the windows.

In all the gures similar letters represent similar parts.

The construction and operation of my improvements are as follows: Upon the roof ot' the car l place a attened tube or chamber, A, Figs. l, Il, lll, which extends along the whole length ol" the body of the car. Upon the under side et' the chamber A are circular openings, B, Fig'. ll, co1'- responding with similar openings in the roof, and forming air-passages into the car. These openings correspond in number with the numbers o" rows of Aseats across the car. Each opening is provided with a valve or register, I), opened and shut by means ot' a stem, t', beneath the root' o1" the car, and within reach ofthe passengers. Upon the chamber A is placed the hood or hollow cone C, having' a collar by which it is connected with and opens into the chamber A. "his collar is equally divided by a diaphragmplate, c, Fig. ll. The hood and collar are made to turn upon bearings surrounding air-openin g correspon din g with the collar in the chamber A, so that the hood may be reversed to face the opposite end or' the car. Across the chamber A, directly under theA collar of the hood, is a lixed dividing-plate, l), Fig. II, which divides the ch amber into two parts, and when the hood and collar are turned in the line of the carin either direction the dividing'- plate in the collar and in the chamber A exactly correspond, so that the currents oi' air which pass into the hood are divided and equally distributed to the two parts ofthe chamber A. The hood is provided with a stem, d', projecting down into the car, so as to be turned in the desired direcwhich is set a plate of glass to till it, are fixedupon each side of the windows in a vertical position, and vibrate upon gudgeons working in brackets afxed upon the side of the car at top and bottom, so that the inner edges of the frames are close to and extend the length ofthe vertical sides of the windows. The breadth ofthe frames will vary from three and one-half to tive inches according to the size of the windows; about one-third the width of the window may be taken as the fair average breadth ofthe leaves. These leaves are operated and made to act as deflectors or otherwise by a horizontal rod or plate, G, which is attached to the car by suitable bearings, within which it is made to slide the required space for moving the deilectors, by means of a suitable gearing, such as a rack or pinion, g g', Figs. I, Ill, a-nd which is to be under the control of the conductor and not of the passengers. Each leaf or deiiector has a bracket or arm bent out from its lower edge horizontally, having at its extremity a vertical pin, which passes into a suitable opening in the adju sting-plate Gr, and is thus hinged to it. The deilectors are so set and connected with the adjusting-plate Gr that, when a leaf or deliector is turned by the plate G so as to stand out at a right angle to the side Jface of the air, all the other defiectors on all the wirdows on the corresponding sides will stand out at the saine angle, and the opposite leaves on the opposite sides of the windows will lie nearly flat to the face of the car, and be turned away from the direction in which the car is moving'. When the deilectors are not in use for carrying off' and outward the air-currents and dust, the conductor slides the plate G and fixes it in position. When the leaves stand with their outer edges together, their sides forming together an obtuse angle between the windows, as shown in Fig. V in top view in horizontal section, the position of the deiieetors when operating as such is shown in Fig. IV, in similar view and section. The arin at the lower edge ofthe deflector, by'which it is hinged to the adjustingplate G, is seen in top view at l l in Figs. IV, V, and in end view or elevation at 1 l, Figs. I, III.

This operation of the above-described devices is as follows: The hood being set with its openingl toward the direction in which the car is moving, the air is, by the rapid motion of the train, iorcibly introduced into the chamber A, and thence into the car, and regulated by the valves and equally distributed by means of the dividing-plates in the collar and across the air-chamber-A, as described. By setting the deiiectors E as shown in Figs. I and IV7 the dellectors on that side oi' each window toward the direction oi' the movement of the car, standing straight out from the face ofthe car, carry the currents of air and dust and cinders passing the line of the windows off and outwardly away from the Windows.

The windows may then be kept open without dust or air entering the Window, the air making its exit from within o'utof the Window, and supplied from the apparatus on the roof. The atmosphere within the car is thus kept pure and in circulation, and passengers may sit at the open windows without being incommoded by the entrance of dust and cinders, or by too strong a current of air frolnwithout. When the deilectors are at the position seen in Figs. III, IV, the windows being` closed, the eiiiect will be still in some slight degree to divert dust from the Windows, and, in cold Weather, prevent accumulations of snow and frost upon the closed windows of the car.

Having thus described lny invention and improvements and the operation of the same, what I claim therein as my invention, and for which I desire Letters Patent, is

l. rIhe combination of a reversible hood or funnel, having a dividing-plate, c1, in the movable collar, with the ilattened air-chamber and the fixed dividing-plate D, constructed in the inanner, and operating for the purposes described.

2. The device and operation of sliding plate G on the side of a railroad car, for the purpose of adjusting and holding in place deiiectOI-S E at the sides of the window in the angles and positions and for the purposes shown.

3. rlhe deflectors or leaves E, constructed in manner and for the purposes shown.

4.. The coinbination'of hood and air-chamber on the roof, constructed substantially as de scribed, with or without the dividing-plates@1 and D, with the deflectors at the windows, constructed and operating substantially as described.
