In addition to the conservation of liquid this
invention has asv its prime objective the reduc
' tion of ?re hazard to airplanes.
‘
With these and other objects in view, as well
as other advantages which may be incident to
the use of the improvements, the invention con
sists of the parts and combinations thereof here
inafter set forth and claimed, with the under
standing that the several necessary elements con
stituting the same may be varied in proportion
and arrangement without departing from the
nature and scope of the invention, as de?ned in
25 the appended claims.
Inv order to make the invention more clearly
understood, there are shown in the accompanying
drawings means for carrying the invention into
practical e?ect, without limiting the improve
30 ments in their useful application to the partic
ular combination, which, for purposes of ex
planation, have been made the subject of illus
tration.

In the accompanying drawings:
Figure 1 is a vertical cross-sectional view of a
tank spout safety cap constructed in accordance
with the invention and showing its application
to a tank having a lid type cover; and
Figure 2 is a vertical cross-sectional View show
ing the application-of the invention to. a tank
spout equipped witha screw or bayonet type cap.
Figure 3 represents a vertical cross-sectional
view of the invention modi?ed to be used on a
45 tank ‘equipped with a very short spout.
Referring to Figure 1, the invention is shown
comprising a conventional tank ?ller spout P and
cap A.
The safety valve or cap proper is shown as the
50 beveled disc H which fits into beveled seat I; the
valve when in closed position being made leak
proof by gasket J which is fastened to valve'disc
H in a'satisfactory manner.
Valve disc H is pivoted at hinge K and is of a
55 diameter su?iciently small to allow its being
It will be seen that projection .M on the under
side of tank cap A acts as an additional lock for
rod C. when disc Hehas been seatedandv this red
snapped into place. It will also be seen thatpro
jection M will not allow the closing of cap ‘A
unless rod vC has been ‘securely: looked under
spring N.
To pour liquid into the tank, cap A is opened
by pivoting about its hinge F. Rod C is then
disengaged from under snap spring N by its be
ing pulled by the attached ?nger grip. , Rod C
and disc H are then raised into a vertical posi
tion and rod C is ?nally snapped into spring clip 20
E as is shown in the dotted portion of the
drawings. This insures the device being kept in
an open position while liquid is being poured into
the tank. A reverse procedure is followed to
close and secure the tank spout.

Figure 2 shows the invention as applied to a
tank spout equipped with either a screw or bay
onet type cap.
In this ?gure, cylindrical pro
jection M, as can be observed, serves as an addi
tional lock for lever C and also serves to prevent
the placing on of the tank cap Q unless rod C
has been looked under spring N. Otherwise, the
functioning of

equipped with
the device is identical to that de
preceding paragraphs.
Figure 3; (modi?cation for a tank
a short spout) disc H closes into
seat I as previously described. The device is
locked closed by sliding latch pin T under steel
ball lock V which is held in position by retainer
X secured to ?ller neck. U is a retaining guide
for latch pin T. Projection M will not allow cap
S to be replaced unless latch pin T has been slid
through guide U and completely locked under ball
V. Otherwise, cylindrical projection M will be
interfered with by the projecting ?nger grip made 45
integral with latch pin T.
It will be understood that the invention and
its component parts may be constructed of metal
or other suitable material.
Other modi?cations and changes in proportion
and arrangement of the parts may be made by
those skilled in the art without departing from
the nature and scope of the invention, as de?ned
in the appended claims.
The invention described herein may be manu

factured and/or used by or for the Government of
the United States of America. for governmental
purposes without the payment of any royalties
thereon or therefor.
What is claimed is:
1. A safety closure for a gas tank or’ the like
comprising a ?lling neck; a cover for said neck;
a valve arranged within‘ said neck in spaced rela
tion to said cover; a rod pivotally connected with
10 said'valve vand accessible from the exterior of
said neck when said cover is open for opening and
closing said valve independently of said cover,
said rod projecting out of said neck and into the
path of movement of said cover when said cover
15 and valve are both open to prevent the closing
of said cover while said valve is open; ‘a projec
tion on the under side of said cover for engage
ment with said rod for preventing movement of
said rod and valve when said cover is closed and
20 latch means for preventing accidental movement
of said rod and the opening of said valve when
said cover is open.

2. A safety closure for a gas tank or the like
comprising a ?lling neck; a cover for said neck;
a valve arranged within said neck in spaced rela
tion to said cover; a rod pivotally connected with
said valve and accessible from the exterior of ‘said
neck when said cover is open for opening and
closing said valve independently of said cover,
30 said rod projecting out of said neck and into the
path of movement of said cover when said cover
and valve are both open to prevent the closing of
said cover while said valve is open; a projection
on the under side of said cover for engagement

with said rod for preventing movement of said
rod and valve when said cover is closed; latch
means for preventing accidental movement of
said rod and the opening of said valve when said
cover is open; and latch means engageable with
said rod for maintaining said cover and valve in
an open position during a ?lling operation.
3. A safety closure for a gas tank or the like
comprising a ?lling neck; a cover for said neck;
a valve arranged Within said neck in spaced rela
tion to said cover; a rod pivotally connected with
said valve and accessible from the exterior of
said neck when said cover is open for opening and
closing said valve independently of said cover,
said rod projecting out of said neck and into the 15
path of movement of said cover when said cover
and valve are both open to prevent the closing of
said cover while said valve is open; a projection
on the under side of said cover; yieldable means
on said projection for engagement with said rod 20
for preventing movement of said rod and valve
when said cover is closed and latch means for
preventing accidental movement of said rod and
the opening of said valve when said cover is open.
4. A safety closure for a gas tank or the like 25
comprising a ?lling neck; a cover for said neck;
a valve arranged within said neck in spaced re
lation to said cover; a manually operable bolt
slidably mounted on said valve for preventing ac
cidental opening of said valve; and a projection 80
on ‘the under side of said cover for engagement
back of said bolt for preventing movement of said
bolt when said cover is closed.
