Twin ventilator fixture
Abstract
A ventilator fixture in the form of a pair of half domes
arranged back to back with each half dome having an open screened
face surmounting an outwardly curving header and each half dome
inwardly having a generally concave member leading inward and
downward around the said header to separate ventilating exhaust
vents leading into an opening of a vehicle upon which the fixture
is attached, the concave members being spaced from each other to
provide a well into which moisture is fed from weep holes extending
transversely across each said concave member at a location near the
bottom of the concavities and a single major weep hole on each side
of the said well to discharge accumulation of moisture therefrom
externally of the fixture.

Claims
What is claimed is:
1. A twin ventilator fixture having a pair of back to back air
inlets spaced a predetermined distance from one another, a pair of
air exhausts, one for each inlet, positioned below and offset
therefrom, a curved duct from each said inlet to each said exhaust,
a trough supporting said ducts and forming therewith a reservoir
for collecting moisture, weep holes arranged in a line across the
lower extremeties of each said duct for discharging water
accumulated by the said ducts into said reservoir, and means
comprising a pair of weep holes for discharging water from said
reservoir.
Description
BACKGROUND OF THE INVENTION
Ventilation of vehicles and the like wherein no artificial or
powered air cooling and circulating is installed has become a
modern requirement in commercial vehicles particularly. The
perishability of cargoes and the comfort and safety of
passenger-operators is of foremost concern in these types of
vehicles, and many ventilating arrangements have been introduced;
however, most of these arrangements are complicated and costly.
SUMMARY OF THE INVENTION
The subject invention is directed to a ventilator of simple
construction having no moving parts wherein circulation of air and
the discharge of water condensate and the like are controlled
automatically by the construction of the invention. A unique
feature of the invention is its adaptability to install upon a
railroad car wherein ventilation of the vehicle is provided by its
motion in either direction upon a track.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the ventilating fixture showing
both halves of the structure as it appears externally.
FIG. 2 is a sectional view of the fixture taken along a line at
right angles to the direction of motion of the ventilator fixture
when it is attached to a moving vehicle.
FIG. 3 is a perspective view of a portion of FIG. 1 showing the
interior of one half of the fixture and the line of weep holes in
the concavity of the deflecting member.
DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1 a base 10 carries side plates 11 and 11a (not
shown), together with the outwardly curving headers 12 at each end
of the base 10 and the dihedral top 14 and the screened openings 13
(only one of which is shown) to form the twin ventilator fixture.
Weep hole 15 is provided for discharging water from a well 21
(later explained herein) to the exterior of the fixture, and
further weep holes 16, 17, 18 and 19 are also similarly provided in
the side plate 11. Similar weep holes 15a, 16a, 17a and 18a and 19a
are provided on the other side plate 11a (not shown).
Now referring to FIG. 2 a supporting member 10a across the width of
the fixture is attached to the base 10 and in turn supports a
troughlike plate 10b extending across the width of the fixture.
Attached at each end of the juncture of the top 14 and the top of
the screened opening 13 is a curved member 20, which extends inward
and downward around and spaced from header 12; forming an irregular
ogee curve therewith, terminating in a lip 22 and extending across
the width of the fixture. The base 10 has extended openings 24
through which ventilation is carried into the vehicle upon which
the twin ventilator fixture is mounted,each opening 24 being
provided with a cut off 25 -- these forming no part of the subject
invention.
Referring again to FIGS. 1 and 2 the plate 10b, side plates 11 and
11a and the convex sides of the curved members 20 together form a
well into which water blown in through the screened openings 13 or
condensed from the air passing through these openings may
accumulate by dripping through holes 23 (See also FIG. 3) in the
members 20, the aforesaid well 21 discharging through the weep
holes 15 (See FIG. 1) and 15a (See FIG. 2). Water accumulating in
the lips 22 of the members 20 may also be discharged from the weep
holes 16 and 17 in side plate 11 and from weep holes 16a and 17a of
side plate 11a. Further provision of weep holes 18 and 19 of side
plate 11 and 18a and 19a of side plate 11a affords discharge of
moisture that might otherwise enter the vehicle carrying the twin
ventilating fixture through the openings 24.
Normally the above described fixture is mounted upon the top or
roof of a vehicle, the fixture being oriented so that the screened
openings 13 face the direction of travel of the vehicle.
Consequently, when both cut off's 25 are open air will be forced in
through one screened opening 13 (the opening facing the direction
of motion of the vehicle) down through the member 20's concave
surface around the lip 22 and through an opening 24 into the
vehicle, thereafter the exhaust will be upwards through the other
opening 24 into the other member 20's concave surface and out
through the other screened opening 13.
