The non-re?llable barrel embodying the sev
eral structures contemplated by the present in
showing one type of tool which maybe employed
vention is of the same general type as that form'
for releasing the locking devices incorporated in '
ing the subject matterv of the application of
R. C. Brushe, filed August 19, 1935, Serial No.
the embodiment shown in Figures 1 ‘and 2 and
also in the embodiment shown “in Figures :5 to~-8,
10 36,775, granted April 13, 1937, Patent No. 2,077,210
and assigned to the same assignee as this ap
'plication.
Non-re?llable barrels of the character disclosed
in the Brushe application comprise generally a
15 closed container having a dispensing opening, a
pipe leading from the opening to a point adja:
cent the bottom of the container, a check valve
associated with the inner portion of the pipe to
preclude flow through the pipe into the interior
V20 of the barrel while providing for ?ow from the
interior of the barrel out through the pipe, means
connecting the pipe with the margin of the dis
pensing opening, and ‘a locking device for secur
ing the pipe against removal, the locking device
2 being of such character that it is releasable only
in a predetermined manner and with the aid of
special releasing tools or devices.
One of the principal objects of the present in
vention is to provide a highly effective type of
(46 Q locking device which is so compactly and closely
organized as to occupy a. minimum space and as
to be susceptible of economical production from
materials and by means of facilities ordinarily
available. The locking device in all of its several
embodiments positively secures the pipe or con
duit against removal by unauthorized persons

The lower end of the pipe ‘I is inter?tted with
panding bushing 28 may be backed up su?iciently
a connecting sleeve I5 and is welded thereto as
to allow the balls 25 to move back against the
reduced lower end 28’ of the bushing. When the
expanding bushing 28 is backed up so that the
reduced portion 28' is in alinement with the balls
then there is no resistance holding the balls in
indicated at I6. The lower end of this sleeve i5
is reduced as indicated at IT and extends down
into the upper end of a valve casing designated
generally at IS.
The valve casing‘ I8 is, as shown, vertically posi
tioned in the lower part of the barrel and has its
lower end permanently and rigidly secured to but
10 slightly spaced from the bottom of the barrel.v
For this purpose foot pieces [9 may be integrally
formed with or suitably secured to the lower end
of the valve casing and welded as at 29 to the
barrel bottom.
The lower end of the valve cas
15 ing is provided with an opening 2| and around the
inner margin of the opening with a downwardly
?aring valve seat 22. A valve 23 coacts with the
valve seat 22 and when engaged with the seat as
shown in Figure 1 closes the opening2l. Stop
position and backing out the connecting ring 8
permits the balls to move axially inwardly by
reason of the increasing pressure exerted by the
inclined surfaces 21 of valve body I3. With the 10
balls in their released position, that is, out of en
gagement with the inwardly sloping surface 2‘! of
the valve casing, a wrench may be applied to the
ring 8 to remove the ring together with the con
duit 1, connecting sleeve I5 and the locking de
vice.
15
The barrel may then be conveniently
re?lled.
'
The form of the invention shown in Figures 5
to 8, inclusive, is identical with that above de‘—
20 pins 24 limit the movement of the valve 23 away ' scribed except that a differently constructed lock
ing'arrangement is provided. As in the other

Means is provided for locking the connecting embodiment of the invention the-conduit 1, which
sleeve I5 to the valve casing and in this form of is‘ connected at its upper end to the barrel ,‘as
the invention comprises locking balls 25 similar before is welded as at [6 to a connecting sleeve‘
to
ball bearings and accommodated in transverse designated at 40. The connecting sleeve has a

openings 26 provided in the reduced lower end I‘! reduced lower portion 4| ?tted in the upper end
of the ‘valve casing l8. Transverse openings 26
of the connecting sleeve. The‘ openings 26 are so
shaped and dimensioned as to limit the distance are provided in this reduced portion of the con
at which the balls may be projected outwardly necting sleeve to accommodate locking balls 25
as before. However, these lockingballs 25in "30
30 therethrough but they do allow su?icient pro
stead of coacting with an inwardly sloping, orin
jection of the balls to enable them to have lock
ing engagement with the tapered inner surface 2'!
of’ the upper end of the valve casing. _
For forcing the balls 25 into locking engage
35 ment with the tapered surface 21 of the valve
casing an expanding bushing 28 is provided. The
' upper portion of the outer periphery of this bush
ing '28 is threadedly interconnected with the sleeve
l5 as indicated at 29. Below‘thisthreaded por
tion 29 .the exterior or outer periphery of the
bushing 28 is smoothed but is provided with an in
clined surface 30 which, as the bushing is
threaded down into the sleeve, acts on the balls
25 to force them out to the position shown in
45 Figure 1. In this position axial movement of the
pipe ‘I and its connecting sleeve 15 relative to the
valve casing I8 is positively limited. Hence, the
ring 8 may not be unthreaded ~from the bushing
4 and the pipe 1 may not be removed.
The upper
50 end of the bushing 28 is provided with slots 3|
designed to coact with a special tool in order to
provide for the manipulation or turning of the
bushing in either direction by authorized persons.
Sucha tool is shown in Figures 3 and 4 and
55 consists of an elongatedrshank 35 provided with
a cross handle 36 at its upper end and with later
ally extending keys 3'! adjacent its lower end
designed to inter?t with the slots 3 i. Of course,
it is to be understood that these keys 3'! and the
60 slots 3| may be of any special shape or con?gura
tion.
In this embodiment of the invention when the
barrel is full of oil-the cap Il may be removed
and any appropriate type of pump maybe con
65 neoted up with the bushing 3 and conduit 1 to dis
pense the oil from the barrel. However, any
down-?ow of oil through the pipe 1 back into the
barrel is prevented by the check valve 23.
Ac
cess to this check valve or removal of the pipe 1
70 1s e?ectively precluded except by persons having
knowledge of the special way in which the de
vice is constructed and equipped with the tool
‘ such as the tool shown in Figures 3 and 4.
By
inserting the tool down through the conduit 1 and
75 engaging its keys 3‘! with the slots 3|, the ex
eluded surface on the valve casing are adapted
to be seated in vertical grooves 42 provided on
the ‘inside of ' thevalve casing, and when so
seated prevent turning of the connecting sleeve “
40 and consequently the conduit 1. Moreover, in
this form of the invention a different type of
structure is provided for moving the balls .to lock
ing positionrand providing for their return to
released‘ position.

A ?anged and apertured supporting plate 43
is secured in the lower end of the connecting
sleeve by‘ means of set screws 44. An’ oscillating
cam 45 is supported on this plate 43 and isiconl
?ned to its oscillating movement by the plate and I ‘
by means of an internal shoulder 46 formed on
the connecting sleeve. This cam is also aper
tured so that the liquid can freely flow through
the cam and the mounting plate. The cam has
curved or inclined surfaces 41 designed to wipe . ‘
against the balls 25 and force these balls out;
wardly until they ride on the high points 49 of
the cam, in which position the balls will be pro
jected into the grooves 42 and the parts .locked
into position. Transverse slots 50 are provided
in the upper surface of the cam so that a tool
such as shown in Figure 3 may be employed to ro
tate the cam. In order to releasably secure the
cam in positioneto maintain the balls projected
into locking position or inposition where the balls ;
are permitted to fall back to released position by
gravity a ball projected detent 5i is provided in
the mounting plate 43 and is engageable with ‘re
cesses 52 and 53 provided on the 'undersuriace of
the cam 45. The extenttowhich the cam‘i'nay be 565

In Figure 9 there is illustrated still‘ another
type of locking device which may’ be employed
for securing the connecting sleeve at the lower
end of the pipe ‘I and consequently also the pipe
1 against rotation. In Figure 9 the connecting
sleeve is designated at 56 and is provided in its
