Improvements in Ventilators applicable to Street and Railroad Cars
and Vessels.
We, MARTIN ROSE RUBLE, President of The Ruble American Blower aud
Injector Co., and THEODORE RUNYON GUIED, Secretary, both of Newark,
County of Essex and State of New Jersey, U.S.A., our Post Office address
being 282 Halsey Street, Newark, New Jersey, U.S.A., do hereby declare the
nature of our invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our present invention has for its object the ventilation of street and railroad
cars and vessels, and relates to such ventilators, which are operated by draft or air
current, simple and durable in construction, reliable and efficient in operation.
The invention consists in the improved ventilator, and the combination and
arrangement of the various parts thereof, substantially as will be hereinafter more
fully described and finally embodied in the clauses of the claims.
Referring to the accompanying drawings, in which like letters of reference
indicate corresponding parts in each of the several figures;
Fig. 1. is a side elevation of a passenger car, provided with our improved
ventilator.
Fig. 2. is an enlarged detail view of the latter;
Fig. 3. represents a freight car, embodying a modified form of the ventilator,
Fig. 4. is an enlarged detail view of said modified form, and
Fig. 5. represents a longitudinal sectional view, of a vessel, embodying our
improved ventilator.
In said drawings, Figs. 1 and 2, a represents a car, provided at or near its ceiling
with ventilator b, consisting of the outer tube c and the inner tube h. The inner
tube is provided with an elbow i, extending through the outer tube and through
the roof of the car, and is adapted to carry the receiving funnel k, the latter being
adjustably jointed to said elbow. Secured to the elbow, and in line with tube h, is
arranged a tube m, extending to almost the opposite end of tube c, and is preferably
tapered, as shown at n, Fig. 2, to correspond in shape with the tapered end of the
outer tube.
Said extending tube m is closed at both ends, and its object is merely to give a
uniform area of air passage throughout the entire length of tube h.
To the outer tube, which is provided with a series of openings g, is also secured
an elbow d, provided with the discharge funnel e, adjustably secured to said elbow.
In operation, when the car is running in the direction shown by the arrow in
Fig. 1, the air will enter through funnel k into the inner pipe, and when leaving
the outlet of said inner pipe, will produce a vacuum and suction, whereby the foul
air is drawn out of the car through openings g into the outer pipe, and from there is
discharged through funnel e.
If the car is running in the opposite direction, each funnel has to be turned at an
angle of 180 degrees and the operation of the ventilator is then the same as above
described.
In the modified form, shown in Figs. 3 and 4, the ventilator b' is secured to the
roof of the car, and the outer tube o¹ provided at its openings 2', with tubes n',
extending downwards through the roof of said car, and carrying tubes m³, arranged
adjustably on and at an obtuse angle to said tubes n'.
All said tubes m' are connected by a rod o¹, so that their position may be
changed, when the car is running in the opposite direction, as will be hereinafter
more fully described.
Within the tube c¹, and extending through almost its entire length, is arranged a

page_text: smaller tube, which again is provided at one end with the receiving funnel k¹, of
such construction, that said funnel will tightly close the inlet of tube h'.
At the opposite end of the ventilator and secured to the outer tube c¹ is arranged
a discharge funnel el, having an enlarged portion e".
In operation, when the car is running in the direction shown by the arrow in
Fig. 3, the air current will enter through funnel into the tube h', and will, when
leaving said tube, produce at its outlet a vacuum or suction, whereby the foul air is
drawn out of the car through tubes m', n' into the outer tube c' and is discharged
through funnel el. The enlarged portion el of said funnel, when passing through
the air, will produce at its outlet an additional vacuum and suction, as will be
manifest.
'
If the direction, in which the car is travelling, be reversed, the funnels k¹ and e¹
have to be removed and replaced on the opposite ends of their respective tubes, and
the tubes m', have to be turned at an angle of 180 degrees (by operating the
connecting rod o).
The application of our improved ventilator to vessels is similar to the application
to cars.
Below each deck is arranged a perforated suction tube c, and the discharge
pipe d with its funnel e is extended above the upper deck of the vessel.
The receiving funnel has to be arranged likewise, as clearly illustrated in
Fig. 5 of the drawings. The operation is the same, as the one described in
connection with Figs. 1 and 2.
As can be seen from Figs. 2 and 4 of the drawings, our improved ventilator can
also be used in connection with a blower, and the receiving funnel will then be
connected by a tube with the outlet of said blower.
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare, that what we
claim is :-
1-In a ventilator for cars, the combination with the car, of a ventilating tube
secured to the ceiling of said car and provided with a series of openings, an elbow
arranged at one end of said tube and extending through the ceiling of the car, a
tube arranged within said ventilating tube and provided with an elbow, extending
through said ventilating tube and through the ceiling of the car, and a funnel,
movably secured to the outer end of said elbow and adapted to catch and receive
the air, when the car is in motion, all said parts, substantially as described and for
the purposes set forth.
2 The method of ventilating a car, when the latter is in motion, consisting in
producing a suction in a perforated tube arranged in said car, whereby the foul air
in the car is sucked into said tube, and in simultaneously discharging said foul air
into the outer atmosphere, substantially as described.
3-In a ventilator for cars, the combination with the car, of a ventilating tube
arranged on said car, a smaller tube arranged within said tube, a funnel adjustably
secured to one end of said inner tube, and adapted to catch and receive the air,
when the car is in motion, and a series of tubes connecting the ventilating tube
with the interior of the car, all said parts substantially as described and for the
purposes set forth.
4 The method of ventilating cars and vessels, consisting in syphoning the foul
air out of the car or vessel, and in simultaneously discharging said foul air into the
outer atmosphere.
