EXHAUST-VENTlL-ATOR FOR CARS.

SPECIFICATION formingpart of Letters Patent No; 743,005, dated November 3, 1903;

Application filed April 2 1903. Serial No. 150,677- (No model.)

To (ZZZ whom it may concern.-

Be it known that I, LEWIS C. LANPHEAR', of

Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Exhaust-Ventilators for Cars,- of which the following is a specification.

This invention has for its object to effect the proper ventilation of railway-cars withstruction, since the appliance is well adapted for use upon the greater numberof cars as now constructed.

Railway-cars both for steamand street railways are generally constructed with what is known as a monitor-top -*that is to say, with an elevated.centrally-located roof and with windows below the roof, which may be opened to secure ventilation. with cars of this character is that the ventilation is improperly accomplishedthat is to say, warmer air escapes from some of the windows, while cold air is allowed to pass in through others, and thus create a draft which is injurious to the passenger. Moreover, the opening of the windows allows the smoke, cinders, and dirt to enter the car and sift themselves over the passengers.

According to my invention 1 place on the side of the monitor-top, along the line of the windows which are there located, a trunk or conduit, with which the interior of the car communicates through the windows just referred to. The ends of this trunk are provided with doors, which may be alternately opened and closed, according to the direction in which the car is moving, it being my purpose to have the door closed at the front end and opened at the rear end, assuming that the front of the car be that endwhich is traveling forward. In addition, the trunk is provided at each end with an opening and with a wind deflector, shield, or wing. These are so connected to the doors that when a door at one end of the trunk is open the adjacent wing is swung outward. The efiect of this is, when the car is traveling rapidly, to in- The difficulty hinged door e.

duce a current of air through the aperture and through the end of the trunk, so that by eduction the warm or vitiated air may be drawn away from the top of the car.

On the accompanying drawings, Figure 1 represents in perspective view the top of a car equipped with the invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents the car in plan View, the parts be ing shown in section. Fig. 4: represents an enlarged section on the line 4: 4 of Fig. 3. Fig. 5 is an enlarged horizontal section of one end of one of the trunks.

Referring to the drawings, a indicates the roof of the monitor-top, and b b represent the upright sides. These sides are provided with the usual glazed movable windows 0 e, which are to be ordinarily found in street-cars and steam-railway cars. Outside of the sides b b are secured two trunks or conduits d d.

These are shown as quadrangular in transverse section, and they rest upon the roof of the car on either side of the monitor-top. The outer sides of the conduits or trunks are glazed at intervals, as shown at d, to permit the passage of light to the top of the car. At each end of each of the trunks there is a The doors of each trunk are connected by links 6 with a longitudinallymovable rod e so that when either one of the doors is open the other is closed. Each rod 6 is adapted to be moved longitudinally by a lever gor' other suitable appliance projecting'down into the car. The outer side of each of the trunks or conduits is-provided.

near each of its ends with a swinging wing f. These wings are so hinged that when they are moved outward they form vanes or deflectors for deflecting the air through the apertures f, as shown by the arrows in Fig. 3.

.Each of these wings is connected .witha rod 8 by a link f When the rod e is moved to the left, as in Fig. 3, it moves the wing at the left end outward to operative position and at the same time opens the door 6, which is adjacentthereto, also closing the other wing f and the other door e. .Assuming now that the car be moving in the direction of the arrow in Figs. 1 or2 and the parts he in the position shown in Fig. 3, the air striking the vane or wing f will rush in through the aperture and out through the end of the trunk. This, I have found, will induce a current of air through the trunk and draw out the foul or vitiated air in the top of the car through the windows 0 c in the moniter-top. These windows of course may be adjusted as ordinarily to suit the occasion or the atmospheric conditions. When the car is to move in the opposite direction, the rod 6 is movedvto the right by the lever g, so as to close the door and wing which were previously opened and open those which were previously closed.

By a ventilating appliance of this character it is apparent that it is impossible for smoke or dirt to get into the car through the upper windows and that the foul air is withdrawn without causing-drafts which might prove detrimental to the health of the passengers.

Although the window 0, immediately opposite the wing f, is shown as opened in Fig. 3, yet better results are obtained by keeping that window closed at all times, as it prevents air induced by the wingf from rushing into the top of the car. 1 I

Of course it will be readily understood that the length of the conduit or trunk may be varied to suit particular requirements and that it may belonger orshorter than the monitor-top.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is 1. An exhaust-ventilator for cars comprising a trunk or conduit extending longitudinally of the car and connected with the interior thereof, said trunk orcond nit being closed except at its rear end and having an aperture 1 at its side near said end, said side being provided with a forwardly and outwardly pro-1v I jecting vane for deflecting air throughthe rear end of said conduit, and means for moving said vane in one direction to close the said aperture or in the other direction to open said aperture and to deflect air thereinto substantially as described.

2. An exhaust-ventilator for cars comprising a trunk or conduit extending longitudinally of the car and connected with the interior thereof, said conduit having in its side near its end an aperture, a vane or deflector pivoted to said trunk and adapted to close said aperture, and means for swinging said vane about its pivot to cause the deflection of air into said trunk through said aperture.

3. An exhaust-ventilator for cars comprising a conduit or trunk arranged longitudinally of the car and communicating with the interior thereof, said conduit having apertures in its sides near its ends, doors at its ends and deflectors or wings at its sides near said apertures, each of said doors and said wings being movable and substantially as described.

4. An exhaust-ventilator for cars comprising a conduit or trunk arranged longitudinally of the car and communicating with the interior thereof, said conduit or trunk having apertures at its sides near its ends and vanes adapted to be moved alternately to close or open said apertures, and means for simultaneously moving said vanes.

5. An exhaust-ventilator for cars comprising a conduit or trunk arranged longitudinally of the car and communicating with the interior of the car, said conduit having doors at its ends and deflectors or wings at its sides near its ends, and means connecting said wings and said doors whereby when the wing and door at one end are closed, the wing and door at the opposite end are opened, and vice Versa.

6. An exhaust-ventilator for cars comprising a trunk or conduit arranged longitudinallyof the car and communicating with the interior thereof, apertures in the sides of said conduits near its ends, wings or deflectors adapted to cover said apertures and also to be moved outward for the purpose of deflecting air inward through said apertures, doors adapted to close the extremities of said trunk or conduit, and means operable from the interior of the car for opening and closing said doors and said wings or deflectors.

In testimony whereof I have affixed my signature in presence of two witnesses.
