SPECIFICATION forming part of Letters Patent No. 274,063, dated March 13, 1883.
Application tiled September 30, 1882. (No model.)
To all whom it may concer-n:
Be it known that I, JAMES WALKER, of Wyoming, Hamilton county, Ohio, have invented a new and useful Ventilating Attachmentfor Railway-Gars, of which the following is a specification.
My invention has for its object a more free circulation of airin railway-vehicles ,and itconsists essentially ot' iiaps or fans that project from a horizontal shaft that extends athwart the ventilator or dome of the car, and is armed on each outer side of ventilator with a wind- -wheel half incased in'suitable deiiectors that `ventilator embodying my invention. Fig. 2 is an end elevation of the same.` Figs. 3 and 4. are a similar section and elevation of a modifi` cat-ion of my invention, a portion of the inclosing-wall in FigA. being broken away. Fig.
V5 is a side elevation of my brake.
A may represent the dome or louvre of a railway-car; B, a shaft that extends horizontally athwart the same. That part of the shaft B which is included within thelouvre is armed wlth naps or fans Q, and its protruding extremities are armed with wheels D D,having` vanes d of the spiralform shown.
E represents a combined canopy and deflector, which unites the offices of protection ofthe wheel from snow, 85o., and of deflecting and concentrating the air-current upon the upper half of the Wheel, thus causing the entire force of the wind to be directed to revolving the wheel in one direction. The spiral form of the wheel-blades insures a practically uniform and constant action'of the air-currents.
An open-work cage or fender, F, prevents accidental contact of passengers or employs with the fans without sensibly interrupting theiiow of air-currents.
A pair of jaws, G G', and a screw, H, constitute a clamp or brake'which enables any occupant of thecar to diminish, slackeu, or arrest the rotation of the fan atwill.
In Figs. 3 and 4 a. modification is shown, in which it is the lower instead of the upper half of the wind-wheel which is covered by the deiiector, the deflector E in said modification resting upon the car-roof. u
Besides the advantage of increased power from two wind-wheelsone on each end of the spindle or shaft to which thefans are attached- I am enabled to make each wind-Wheel smaller to get the samepower that would be required from one, and my device therebyloollis much neater on the car than one large wind-wheel does. I am also enabled to locate my windwheels in a much less objectionable place than on the top of the upper root'. In fact, some rail-A roads cannot permit a wind-wheel to be placed on the upper roof, for the simple reason that their cars have only two inches clearance in some tunnels and bridges, while any car with my wind-wheels can go safely through any tunnel or any bridge the car can go through without them. The wings ofthe wind-wheel,
running in the length of the wheel from one quarter ofthe diameter to the next quarter, expose at all times to the wind a full Wing, or two halves or portions of two, equal to one wing, and thereby keep up a continuous, even motion of the fans inside. y
My brake is so easily reached and so simple that any passenger, although he may never have seen it before, will at once understand how to regulate the speed of the fans or arrest them altogether should it be found necessary to do either for the comfort of the passengers at any time, or to allow them to move should they be standing still. 4
I am aware that descriptions exist of public vehicles ventilated by fans within the car, impelled by vanes or wheels which are rotated by the impact of the outside air, and that devices exist for governing the Speed of such fans and protecting them from Contact with objects within the vehicle, and I therefore do not claim such devices, broadly.
I claim as new and of my inventionl. Aventilating apparatus for railway-cars, which consists ot' shaft B, that extends horizontally across'the dome or louvre A, within which it is armed with fans C, and outside ot' which it is armed with wind-wheels D D', in
the described combination with the canopy' and deflector E, the whole being arrangedand operating as set forth.l
