An Improved Device for Ventilating Railway Cars.
I, CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street, in the City
of London, Solicitors of Patents, do hereby declare the nature of this invention, a
communication to me from abroad by Brisbane Marshall Turnbull, Farmer of
Scranton, in the County of Jackson, State of Mississippi, and Bronnlee Wickliffe
Taylor, Merchant of New Orleans, State of Louisiana, in the United States of
America, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention has relation to improvements in devices for ventilating railway cars,
and collecting and removing dust from the air admitted, and the novelty will be
fully understood from the following description and claims taken in connection with
the annexed drawing in which:
Fig. 1 is a side view of a portion of my improved device removed from the
car.
Fig. 2 a front view of the entrance portion.
Fig. 3 an interior view of the main pipe, showing the circularly arranged brush
therein.
Fig. 4 an end view of a car with my improvements applied.
Fig. 5 a view of the railway car showing my improvements in side elevation
therein.
Fig. 6 a view of one of the screens removed from the car.
Fig. 7 a detail view of one of the lags or brushes which I employ on the inner
side of the screen.
Fig. 8 a side elevation of one of the brushes.
Fig. 9 a view of one of the brushes and screens in position, and
Fig. 10 a similar view.
Referring by letter to the said drawing, E indicates a pipe which is provided with
numerous perforations and has at opposite ends a downwardly directed branch C,
which is designed to extend a sufficient distance down the end _walls of a car on the
inner side thereof and carries at its lower end a removable cap F; the pipe E, which
is a continuation of the branch of C, assumes a position on the inner side of the car
and preferably along the ceiling.
A indicates an entrance which is of a flaring form. This flaring entrance
communicates with the vertical branches of the pipe and has a screen B at its
contracted portion or point of communication with the said pipe C; the flaring mouth
or entrance portion A being arranged upon the outer side of the end walls of the car
so as to collect the air or atmosphere during the travel of the train.
D indicates a brush which may be of wire, hair or other suitable material. This
brush is arranged within the vertical branches C of the pipe at a sufficient point above
the flaring mouth or entrance and is designed to remove cinders and other impurities
which drop to the bottom of the said branch and may be removed by taking off
the cap F.
With a device of this construction a car or train of cars may be thoroughly
ventilated by the admission of pure air, and foul and impure air which arises in the
car carried off and discharged by suction through the perforations in the pipe E.
P indicates a rectangular frame or screen which I arrange in the end wall of a car
on the side opposite my ventilating device. This screen is backed by brushes L,
consisting of strips or lags filled with hair so that any dust, cinders or other
impurities which may enter the screen will be checked by the brushes, the screen P
being held in a suitable ordinary wire screen K, which acts in conjunction with the
rushes. From the foregoing description taken in connection with the annexed
Irawing, the operation and advantages of my invention will be obvious.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:
The ventilator for railway cars consisting of a perforated pipe extending from
end to end of the car and having a downward imperforated extension at each end
thereof, said extensions being each provided with a brush therein a removable cap at
the open end thereof, and a flaring air collector located between the brush and the cap
and provided with a screen substantially as specified.
Dated this 24th day of August 1889.
