Letters .Patent No. 86,780, dated Febmwry 9, 1869.

RAILROAD-CAR VENTILATOR.

The Schedule referred to in these Iiettere Patent and making part of the same.

To all 'whom fit maf/y concern: ,t

-the accompanying drawing, andthe letters of reference marked thereon, making part of this specification, in which- Figure l is a front view of' anar-window with my improvement attached.

vFigure 2 is an end view of a car-window with the same attached.

Figure v3 is aV top or edge view ofra car withv the same attached, a: x representing the position of the wings or blinds when the car is going in one direction, and yg/when it is going in the` oppositedirection, the direction being indicated by arrows.

Figure 4 shows the connecting-rod, which operates the wings or blinds.

The object of om' invention consists in a simple and practical arrangement, whereby we are enabled to deiiect the dust, smoke, sparks,'and cinders, and at the same time create a strongdranght of air from the interior of the car.

We are aware that manyeiforts have been made, and plans'suggested, the object ofwhich was to attain the result accomplished by our arrangement; but it is an admitted fact that they are all either so complicated, expensive, cumbersome, and unwieldy, as to fail to gain for them that degree of popularityfwhich promises their adoption, to any Vgreat exteii't, -by railroad companies.

The nature of our invention consists'in attaching directly to the side of a car, by means of an ordinary hinge, or other equivalent device, a series of wings, or detlectors, so arranged that every window is provided with a pair, one being secured at each side of, the same. Each pair of these wings, or deflectors, is so connected, by means of a bent connecting-rod, that it operates automatically, its relative position and action depending entirely on the motion of the train and the direction in which the same is travelling.

v lt will be observed that, by our arrangement, one of the wings'or blinds always occupies a position directly alongside of the car, and nearly parallel thereto, while the position of the other is at right angles to the side of the car, its inner surface being in a direct line withthe side ofthe opening in which its the window-frame and sash.

Our invention is especially valuable in this regard: It is attached directly to the car, and the same can be done at a most trilling expense, its construction and the material used being of the cheapest character.

.The successful operation of our ventilator depends in no manner upon any arrangement of mechanism, 'dame-work, or casing, and the wings or blinds being united and operated, as they are, by independent rods, should occasion require a seat to be reversed, or, for any other reason, should it be deemed desirable to change the position of the wings or blades, the same can readily be done simply by moving the' rod, when the position of the wings will instantly be reversed, and this accomplished without affecting in the slightest degree the relative position`of any other of the series.

Another great advantage of our plan-is found in the fact that the ventilator can he attach ed to any car now in use, no matter what its plan' of construction may beand should itbe desirable., for any reason, to remove the ventilator, -the same can be done quickly, by loosening the screws which fasten the hinges to the framework of the car-window.

To enable othersskilled in the art-to make and use our invention, we will now proceed to describe its construction and operation.

. A is arailroad-car, B, the Window-frame, and C, the sash, all constructed and operated in the usual manner.

D D is a series of blinds or deectors, which are attached immediately to the sides of the cars by means of ordinary hinges, cl d, or other equivalent device. These blinds D D are made of smooth plank, or other suitable material, and are oblong in form. They may be varnished, painted, or stained by any ordinary process, so as to represent any desired color. 'llhey may also be made perfectly straight, but we preferto make them slightly wedge-shaped, as by this means we are enabled tol obtain a broad bearing against the car, which, of course, will require less resisting-force on the part of the hinges, and with but a triiing addition to the weight of the blinds. These wings D D, it will be observed by referenc'e to g. 3, are so hinged that one of the same is always held at right angles to the side of the car, its inner surface being ou a direct lineJ with the side of the opening in which fits the window-frame or sash. This position of the wing securely guards the open window from the influx of sparks, Sto., by forming a vacuum outside of the window, thus causing a current from the inside of the car outwardly,I while, at the same time, the other Wing is folded against the side of the car.

Eis a straight metallic rod, its ends being bent down in-the forni of elbows, as clearly shown in tig. 4.

The bent ends of' this rod fit in suitable openings, e e, arranged in the upper surfacelof the wings or bliuds. rlhese rods are applied in the, manner clearly shown, and firmly unite the blindstogether. Thus, it will be seen that a rodat each window connects a pair of blinds, and the action of each set of deflectors is rendered purely independent, and i u no manner depends on the adj oiniug set, on either side, for its operation or relative 'position.

. The blinds or wings being thus united, the motion of the car will operate them automatically, so that they will be in the position shown at a: x, iig.` 3, when the ear travels in the direction of the arrow, and at y y of the same' figure when travelling in the opposite direction, so that the einders, smoke, lsparks, 85e., are all entirelyexeluded from` thejear, and a strong current of air is formed along the outside of the same, thoroughly Ventilating the car by drawing out, as it does, the heated and impure air.

Having thus fully described onr invention, What We claim thereinas new, and desire. to secure by Letters Patent of the United States,'is

A series of wings or deeetors, D D, attached directly to the side of the ear, when eaeh pair is s0 united,

by an independent 'bent rod, that while one is folded against the car the other is held at right angles to the side of the same, its inner surfaee being on a line with the side of vthe openingr in which ,fits the window-frame .or sash.

lIn testimony whereof, we have signed our names to this specification, in the presence of two subscribing
