The present invention is capable of embodi
10 ment in forms for use on the oil ?lling or oil re~
ceiving pipes of engines of various characters and
may be embodied either in the form of attach
ments or original features or parts of the engine
structures. Throughout the following detailed
15 description of the invention I will disclose sever
al typical embodiments used on the oil receiving
pipes as found in the various types of automotive
engines which forms may be considered as appli
ances or attachments, or as devices or parts pro
20 vided on the engines as originally constructed.
It is to be understood that the present invention
is not to be construed as limited to the speci?c
forms or applications about to be described, but
that it is to be taken as including any features
25 or modi?cations that may fall within the scope
of the claims.
The embodiment of the invention illustrated in
Figs. 1, 2, and 3 of the drawings includes, gener
ally, a body l0 forming apart of or a continuation
30 of the oil receiving pipe I l of an engine E, a cover
l2 for the upper end of the body it], and a cutter
l3 carried by the cover l2 and operable to open
sealed containers.
The body 10 is a tubular member constituting
35 a continuation of the upper end portion of the oil
receiving pipe and breather pipe of the engine E.
The lower end of the ?tting or pipe I l communi
cates with the interior of the engine. In the
particular engine structure illustrated in the
40 drawings, the receiver or pipe I I has its lower end
held in or received by an angular tubular boss Ill
projecting from the body of the engine. The pipe
H is vertical, it being understood that the form
of the invention being described is capable of use
45 in connection with tilted or inclined receiver and
breather pipes. The body l0 projects upwardly
from the upper end of the pipe I l, and in accord
ance with the broader aspects of the invention,
may be applied to or attached to the pipe portion
of the receiver in any suitable manner. In the
particular case illustrated, the body iii has a
lower cylindrical portion l5 tightly ?tting into the
upper end of the pipe ii that may be rigidly at
tached. to the pipe if found necessary or desirable.
55 The body l0 ?ares outwardly and upwardly so
that its major upper portion i6 is considerably
larger in diameter than the portion l5 and pipe
H. The upper edge of the body iii may lie in a
plane substantially normal to the longitudinal
axis of the body and may be slightly turned out
Wardly or rolled.
The cap or cover [2 normally extends across
the open upper end of the body ID to prevent
objects and foreign material from. entering the
65 receiver. The cover l2 carries the cutter l3 and
operates to clean or ?lter the air breathed by the
receiver during operation of the engine.
In the
form of the invention being described, the cover
[2 is hinged or pivoted to the upper end of the
70 body It] so that it may be swung from the closed
position illustrated in Fig. 1 to the open position
illustrated in Fig. 2.
The cover l2 includes a
main body part or disc ll adapted to seat on. the
upper edge of the body Hi. The cover disc I‘!
75 is hingedly connected with the upper end portion
Fig. 2.
The stop 19 is adapted to cooperate with
the exterior of the body ill upon the cover reach~
ing the fully open inclined position to step further
opening movement. A spring ?nger or clip 20 is 10
provided on the disc IT at a point diametrically
opposite the hinge connection to engage under the
rolled upper end of the body to releasably hold
the cover in its closed position.
The disc IT is
perforated, being pro-vided with a multiplicity of 15
spaced openings 2|.
The cover l2 may include an air ?ltering or
straining means. A cup 22 is attached to the
under side of the disc l'l' and holds or carries a
suitable air ?ltering material 23. such as steel 20
Wool, or the like. A plurality of spaced open
ings or perforations 2ta is provided in the bottom
or under-side of the cap 22. A deflector plate 24
may be provided on the upper side of the cover
[2 to laterally deflect the oil laden and smoke 25
fumes from the engine and to prevent the en
trance of Water or foreign material into the re
ceiver. The plate 24 is attached to the disc I‘!
by a rivet 25 and is spaced from the disc I’! by
a. spacer 26 on the rivet. The peripheral portion
of the plate 24 is rolled or turned down to the
disc H and is notched or perforated to admit and
pass air.
The cutter i3 is attached to the under side of
the cover I 2 to be housed within the body l9 when 35
the cap is in its closed position and to be exposed
and accessible for use when the cover i2 is in its
opened position illustrated in Fig. 2 of the draw
ings. The cutter l3'is formed so that it is oper
able to cut a large clean opening in an end of a 40
container pushed or forced on to it, and is posi
tioned on the under side of the cover [2 so that
the contents of the container may drain directly
into the body iii. In the preferred construction,
the cutter I2 is substantially U-shaped in trans 45
verse cross section having two spaced side parts
21 joined by a transversely curved connected part
23. The cutter i3 is comparatively long but is
proportioned so that it is freely received by the
enlarged upper portion 96 of the body when the 50
cover i2 is in the down or closed position. The
connecting part 28 of the cutter is connected ad
jacent one end to the under side of the cup 22. In
the particular case illustrated, the cutter is at:
tached to the cup 22 by spaced rivets 29. A 55
spacer 38 is provided to space the connecting por- ’
tion 28 of the cutter from the under side of the
cup in parallelism with the under side of the cup.
In accordance with the invention, the cutter i3 is
attached to the under side of the cup 22 adjacent
the periphery of the cup and adjacent to and in
diametric alignment with the hinge connection
between the cover and the body IS. The cutter
it extends diametrically across the under side of.
the cover 12 from its point of connection with the 65
cover. The longitudinal edges 3i oi the side parts
27 are‘ pitched or inclined and converged to a
point 32 at the outer or free end of the cutter.
If desired, either one or both sides of the point
portion or the cutter may be beveled. The in 70
clined edges 3i are ?at and substantially normal
to the side surfacesof the parts 21. Spaced drain.
openings 33 may be provided in the cutter i3 at
points adjacent the inner end of the spacer 30.
Means may be provided for releasably holding 75

trated in Fig. 2 of the drawings. In practice, any
suitable type of device may be employed to re
free to drain into the body Ill and pipe H. The
cup 22 and spacer 30 space the cutter l3 inwardly
leasably hold the cover in the open position. In
the case illustrated in the drawings a releasable
holding‘ device 34 in the form of a ?exible mem
so that the opened lower portion of the container
is inwardly of the side wall of the body H] to
prevent the oil from splashing or falling outside
ber is attached to the cover |2 adjacent its hinged
connection with the body Ill. The releasable
holding device 34 is bent or curved to have its free
of the body. The openings 33 in the cutter |3
end pass through an opening 35 in the wall of the
body it when the cutter I2 is moved to its open
position. A bend or notch 36 is provided in the
device 34 to receive an edge portion of the opening
35 and the ?exible device 34 is formed so as to
spring or yield as its end enters the opening 35 to
the end of the container. The container is sup
ported on the cover and cutter so that the user
does not have to hold it or steady it as it drains.
After the contents have drained from the con
dependably hold the notch 35 in cooperation with
the wall of the opening 35. Upon the cover l2
being shifted to its fully open position, the end
of the releasable holding device 34 enters the
opening35 and its notch 36 receives the edge
portion of the opening to retain the cover in the
open position. The device 34 may be released by
bending it upwardly to disengage it from the wall
of the opening 35.
*
It is believed that the utility and practicability
of the form of the invention illustrated in Figs. 1
to 3 inclusive of the drawings will be readily ap
parent from the foregoing detailed description.
The cover I2 is normally in its down or closed
30 position illustrated in Fig. 1 where the cutter I3
is fully housed within the enlarged portion N3
of the body Ill. During operation of the engine
E, air is free to pass in and out through the per
forations in the disc l1 and cup 22 and is ?ltered
by the material 23. When it is desired to open a
sealed container of oil and drain its contents into
the receiver of the engine, the cover My is opened
and swung to the fully open position where it is
inclined as illustrated in Fig. 2 of the drawings.
The stop |9 and the releasable holding device 34
operate to hold the cover in this position. The
container may then be pushed or forced down on
the cutter l3 so that the point 32 of the cutter
pierces an end of the container immediately ad
45 jacent its peripheral edge. As the container is
pushed‘down on the cutter l3 the space between
the under side of the cup 22 and the part 28 of
the cutter receives the adjacent wall of the con
tainer. In practice, the spacing of the cutter l3
' from the. under side of the cup 22 is such that the
bead commonly provided on the peripheral edges
of sealed containers is slidable between the oppos
allow the oil from the outside of the cutter to
freely drain out through the opening formed in
tainer, the container may be readily pulled up
wardly and disengaged from the cutter. The re
leasable holding device 34 may then be released
to allow the cover l2 to be returned to its closed
position. The sealed containers of oil may be
easily and quickly opened by the device and their
contents directly drained into the receiver of the 20
engine. The containers are dependably supported
in an inclined position on the cutter to insure the
draining of all of their contents into the receiver.
The provision of the cutter l3 on the under side
of the cover l2 does not in any way complicate
the structure or interfere with the breathing
function of the receiver. When the cover I2 is
in its opened position, the cutter |3 does not in
any way interfere with the pouring of lubricant
into the open end of the receiver.
The embodiment of the invention illustrated in
Figs. 4, 5, and 6 of the drawings includes, gen
erally, a body 40 forming a part of or adapted to
he applied to the lubricant receiver ||a of an en
gine, a cap or cover 4| for the upper end of the
body 45), and a cutter 42 in the body 40 operable
to a position where it is adapted to open sealed
containers after shifting of the cover 4| to an
open position.
The body 43 is adapted to constitute an exten 40
sion or continuation of the upper end of the re
ceiver I la. The invention contemplates either
the rigid attachment of the body 40 to the re
ceiver H3 or the applying of the body 40 to the
receiver in any suitable manner. In the particu 45
lar case illustrated in the drawings, the body 40
includes a flared or substantially inverted frustro
conical major portion 43 and a cylindrical lower
portion 44 ?tted into the upper end portion of
the receiver H“. The upper edge of the body
46 may be horizontal or in a plane normal to the
longitudinal axis of the body and may be rolled
ing surfaces of the cutter and cup. In this man~
as illustrated.

The cap or cover 4| is pivotally attached to the
body 40 so that it may be shifted between a closed 55
position over the upper end of the body and an
open position out of vertical alignment with the
upper end of the body. The cover 4| includes a
guide the container as it is pushed downward on
the cutter l3. In practice, the point 32 of the
cutter may be spaced inwardly from the periphery
ofcthe cup 22 so that the bead at the edge of the
container'may be brought against the under side
60 of the cup to be Cruided thereby as the container is
advanced on to the cutter. The pointed end of
the cutter pierces the end of the container adja

ners of the'edges 3| cut or shear the end wall of
the container as it is pushed down on the cutter
thus enlarging the cut inwardly. The ?at edges
substantially disc shaped member 45 proportioned
to project beyond the upper edge of the body 40
when the cover is in the closed position.
The
peripheral edge portions of the member 45 are
curved downwardly and a perforated disc shaped
plate 45 is arranged at the lower peripheral edge
of the disc 45 and is suitably attached to the disc. 65
The plate 45 is spaced below the main part of the
3| engage the flap outlined by the cut and roll
disc 45 to provide a space for holding an air
it upwardly and outwardly, leaving the opening
screening or ?ltering'material 47. The peripheral
portion of the plate 46 projects beyond the upper
end of the body 40 and is perforated to allow for 70
the breathing of air through the ?ltering mate
rial 4‘! in the cover. A pivot pin 48 extends
through an opening in the plate 46 and a block
49 on the upper edge portion of the body 40 to
pivotally attach the cover to the body. A spring
substantially unobstructed. The spacer 3Q limits
the downward movement of the container on the
cutter i3 and aids in supporting the container.
When the out has been made, the container is
supported in an inclined position on the cutter l3
with the opening formed by the cutter in its low
'15 ermo‘st portion directly over the open-mouthed
4
2,114,459
50 may be provided to normally yieldingly hold
engagement of the container with the guide and
the cover in proper engagement with the upper
cutter and the engagement of the cutter with the
walls of the opening it has formed in the con
tainer end effectively supports the container in
edge of the body.
The cutter 42 for opening the containers of oil
is mounted on the inner side of the main body
portion 43 in a manner so as to be shiftable or
operable between a position entirely within the
body 40 and a position where it projects 'from the
upper end of the body. In the embodiment of the
invention being described, the cutter 42 is pivot
ally attached to the body 4|) so that it may be
swung between the inoperative position in the
body and the operative position where it projects
from the upper edge of the body. The cutter 42
15 is substantially U-shaped in transverse cross sec
tion having spaced side parts 5| and a transverse
ly curved connecting part 52. The longitudinal
edges 53 of the side parts 5| are inclined and
join at a point 54 at an end of the cutter. The
20 edges 53 are preferably ?at and substantially
normal to the side surfaces of the parts 5|.
Spaced drain openings 55 are provided in the
cutter 42 adjacent its broad end.
A guide 56 is provided in conjunction with the
25 cutter 42 to guide containers on the cutter. The
guide 56 is an elongate member spaced from and
substantially parallel to the outer side of the
cutter part 52. The guide 56 may be slightly
curved in transverse cross section to effectively
30 guide cylindrical containers. A spacer 51 con
nects the broad or lower end of the cutter 42 with
the guide 55. The cutter and guide may be weld
ed to the spacer 51. The inner or lower end of the
guide 56 is pivotally connected with the body 40.
35 A pivot pin 58 extends through openings- in the
guide 56 and a connecting member 59 on the inner
wall of the body 40 to pivotally connect the cutter
and guide with the body. The cutter and guide
are pivotally mounted on the inner ?aring wall of
40 the body 40 at a point spaced below the upper
edge of the body and at a point substantially dia~
metrically opposite the pivotal connection be
tween the cover 4| and the body. The cover 4|
is normally in its closed position where it seats
45 against the upper edge of the body 40 and oper
ates to ?lter the air breathed by the engine.
When it is desired to pour the contents of a
container of oil in the crank case of the engine,
the cover 4| is swung to its open position and
the assembly of the cutter 42 and guide 56 is
pivoted upwardly to the projecting position illus
trated in Fig. 5 of the drawings. When the cutter
42 is in its projecting operative position, the
outer side of the guide 56 bears against the inner
55 wall of the body 40 providing an effective support
for the cutter in addition to its pivotal mounting.
The bead B at the peripheral edge of the con
tainer C is brought into engagement with the
inner surface of the guide‘ 56 and the container
60 is pushed or forced downwardly on the inclined
cutter 42 so the point 54 of the cutter pierces the
end of the container. The guide 56 insures the
engagement of the point 54 with the end of the
container immediately adjacent its peripheral
65 bead B and downward movement of the container
on the cutter causes the outer longitudinal
corners of the edges 53 to cut or shear the con
tainer end, thus enlarging the opening inwardly.
The force exerted on the container C when it is
70 opened on the cutter 42 is directed downwardly
and inwardly toward the center of the body 40
so that it has no tendency to tip the assembly of
the cutter and guide. The spacer 51 limits the
downward movement of the container C and aids
75 in supporting the container on the cutter. The
the inclined position on the cutter. The contents
of the container are free to drain directly into
the open mouth of the body 49 and flow into the
crank case of the engine. The drain openings 55
allow the oil behind the cutter to entirely drain
out of the’ container. As the container is effec 10
tively supported on the cutter the user is not
forced to hold the container as it drains. After
the container is entirely drained, it may be eas
ily disengaged from the cutter and guide. The
assembly of the cutter and guide may then be 15
pivoted to its down position within the body 40
and the cover 4| swung to its closed position over
the upper end of the body.
The form of the invention illustrated in Figs.
7 and 8 of the drawings includes generally, a 20
body 6|], a cap or cover 6| for the body, and a
cutter 62 shiftable between a position within the
body 60 and a position where it projects from
the upper end of the body.
The body 60 is adapted to be attached to or to 25
form a part of the lubricant receiver Nb of the
engine and is a tubular member forming a con
tinuation of the receiver. The body 50 includes
a cylindrical lower portion 53 engaging or ?tting
into the receiver part ||'b and a major portion 64 30
that is laterally enlarged so as to be adapted to
receive the lower portion of a tilted container.
The walls of the laterally enlarged portion 64 of
the body are inclined upwardly and outwardly.
The upper end of the body 60 may be straight
and horizontal and may be rolled.
The cover 6| is pivotally attached to the body
50 so as to be operable between a position where
it extends across the upper end of the body and
a position where it is out of alignment with the 40
body opening.
The cover 6| may be similar to
the cover 4| described above, that is, it may be a
hollow substantially disc-shaped structure ?lled
with steel wool, or the like, 65. The lower wall of
the cover 6| is perforated and overhangs the
' upper edge of the body 60 to allow for the breath
ing of the engine through the receiver. A pivot
‘.pin 66 pivotally attaches the cover 6| with the
upper edge portion of the body 60.
The cutter 62 is longitudinally shiftable or .
movable between a position entirely within the
body and a position where it projects from the
upper end of the body. The cutter 62 is similar
to the cutter 42 described above, being substan
tially U-shaped in transverse cross section.
The :
cutter 62 has two spaced side parts 61 and a
transversely curved connectimg part 68.
The
longitudinal edges 69 of the side parts 51 are
inclined upwardly and outwardly and converge
to join at a point 19 on the upper end of the 60
cutter. The edges 69 are preferably ?at and sub
stantially normal to the side faces of the parts
51. Spaced drain openings '|| may be provided
in the broad end portion of the cutter. A guide
‘i2 is provided in connection with the cutter 82
for carrying the cutter and for guiding the con
tainers on to the cutter. The guide 12 is spaced
from and substantially parallel with the curved
outer portion 58 of the cutter and is connected
with the cutter by a spacer 13. The spacer 13 70
may be welded to the lower end portion of the
guide 12 and the lower end portion of the cutter
part 68. The guide 12 extends upwardly beyond
the pointed upper end of the cutter. In accord
ance with the invention, the guide 72 has sliding 75
5
2,114,459
bearing engagement with the upwardly and out
wardly inclined wall of the enlarged body por
tion' 64 and constitutes a carrier for the cutter,
carrying or supporting the cutter for movement
between its position in the body and its position
projecting from the body. A slidable connection
is provided between the assembly of the cutter
and guide and the body 56. A longitudinal slot
74 is provided in the guide 12 and slidably receives
10 a pin or rivet 15 projecting inwardly from the
inclined wall of the body 60. The inner head of
the rivet 15 engages the inner side of the guide
12 to retain the guide in proper sliding bearing
engagement with the inner wall of the body 60.
15 It will’ be apparent how the assembly of the cut
ter 62 and guide 12 are shiftable orslidable on
the inclined wall of the body between the posi
tion illustrated in Fig. 7 of the drawings and the
projecting operative position illustrated in Fig. 8
of the drawings.
'- Means is provided for releasably supporting or
holding the assembly of the cutter 62 and guide
12 in its projecting operative position. A latch
or stop 76 is carried by a spring arm 11 and is
adapted to be engaged by the lower end of the
guide 72.
The stop 18 is adapted to project
through an opening 18 in the inclined wall of the
.body 60, and when in this position, is engageabl-e
by the lower end of the guide 12 to support the
30 assembly of the guide and cutter 62 in its up or
projecting position. The spring arm Tl normally
yieldingly urges the stop 75 inwardly so that when
the cutter 62 is shifted to the up or projecting

‘pierces the end of the container immediately ad
jacent its periphery and the longitudinal outer
the entire contents of the container are received
by the body and are prevented from splashing or
over-flowing from the upper end of the body.
After the oil has drained from the opened con
tainer, the container may be easily disengaged
5
from the cutter and guide, and the stop 16 may be
pulled outwardly so that the guide and cutter may
be slid down to the inoperative position within the
body.
The cover 6! may then be swung to its
closed position. The cutter 62 is always available
for use and may be easily and quickly shifted to
its operative position after the cover 6| has been
swung to the open position. The cutter and

It is believed that the operation of the embodi
ment of the invention illustrated in Figs. 12',‘ 13,
and 14 of the drawings will be understood from
the foregoing detailed description. The cutter
I52 is normally entirely within the body where 45
the tongue I16 supports the'as'sembly of the cut
ter guide and cutter carrier in the body. When
ly within the body and an operative position
where it projects from the upper end of the body.
The cutter I 52 is similar to the cutter 91 described
above, being substantially U-shaped in cross sec
tion;' The two side parts I58 of the cutter are
parallel and in substantial vertical planes, while
the curved connecting part I59 of the cutter is in
nal edges of the side parts I58 are inclined up
55 wardly and outwardly and converge to a point I6I
at the upper end of the cutter. Drain openings
I62 are provided in the lower end portions of the
side parts I58 and are separated by a tongue I63
which is a continuation of the connecting por
tion I59. The lower end of the tongue I63 may
be curved or bent inwardly as illustrated in the

it is desired to open a sealed container of lubri
cating oil and drain its contents into the crank
case of the engine, the cover I5I is swung to the 50
open position so that the projecting tongue I10
cutter carrier upwardly in the body. When the
ring I65 of the cutter carrier reaches the upper
end portion of the body where its key ways I13
are disengaged from the keys I12, it may be
turned so that its lower end may engage the up
per ends of the keys to support the carrier and
cutter ‘1n the up position. The cutter I52 and 60
the guide I66 then project from the upper end
of the body I50 so that a container may be pushed
downwardly on the cutter to be opened. In
opening the container, the bead at its lower end
is arranged against the inner surface of the pro
jecting portion of the guide I68 and the container
is pushed downwardly so that the point I 6I of
the cutter pierces its lower and immediately ad
jacent its periphery. The outer longitudinal
corners of the edges I60 operate to out or shear 7 U
the end wall of the container as the downward
movement of the container continues, thus en
larging the opening.
The edges I 60 are prefer
ably ?at so that they engage the ?ap outlined by
the cut to roll it back out of the opening formed.

As the guide I68 and the outer
portion I59 of the cutter are inclined, the con
tainer when opened. and supported on the cutter
and guide is also inclined and has the opening
formed by the cutter in its lowermost part. The
oil is free to drain from the opening made by the
cutter and discharges through the openings it?
directly into the lubricant receiver of the engine.
As the container is tipped or inclined when opened
10 and supported on the cutter, its entire contents
are free to quickly drain into the receiver. The
drain openings I62 in the cutter allow the free
drainage of oil from behind the cutter. After
the contents have completely drained from the
15 container the container may be removed. or dis
engaged from the cutter and guide so that the as
sembly of the cutter guide and cutter carrier
may be returned to its normal position in the
body. To return the assembly to its down or
20 normal position, the assembly is turned so that
the tongue H0 is in vertical alignment with the
notch I‘H in which position the key ways H3
register with the keys I12 and receive the keys al~
lowing the assembly to be moved downwardly in
25 the body. The tongue H0 is received by the
notch I'll in the upper end of the body and is
effectively retained in the notch by the cover I5 I.
The container opening cutter I52 of the device is
normally concealed and protected within the oil
30 receiver of the engine but is at all times accessible
for use. The cutter may be quickly shifted to its
up or operative position and the containers may
be quickly opened by the cutter so that their
contents may completely drain directly into the
35 lubricant receiver of the engine.
