CAN OPENER AND DISPENSER
Theodore H. Gerdes, Dike, Iowa
Application April 19, 1937, Serial No. 137,736
6 Claims. (Cl. 221-23)
My invention relates to improvements in can
openers and dispensers, and it is an object of
my improvements to supply a device of this
class at once inexpensive, convenient in its uses
5 and suitable for operation in garages, ?lling
stations, or elsewhere where quick service is in
dispensable and required.
Another object of my improvements is to in
clude in the elements coacting in the mech
10 anism of my said contrivance, means for releas
ably resiliently locking the device when in
on cans, thus relieving the operative from
necessity of keeping manual control of
means when holding, transporting or using
15 device at the times mentioned.

the front thereof by readily releasable means

whose upper edge or edges may be indented at
3 to receive the lower head ?ange of the can to
prevent dislodgement while being operated upon.
The projection or projections 2 terminate in a
?at ring 4 to receive the lower end part of an
erect tubular or cupped standard 8, and a set
screw 5 may be used to adjustably secure said
elements together to permit the ring base I to be
raised or lowered as desired, but this ring base
may be permanently ?xed on the standard. A 10
handle l2 may be ?xed on at the rear to said
standard. A coiled compression spring ‘1’ is po
sitioned in the lower part and hollow of the
standard to extend upwardly therein a suitable
distance, and a cylindrical stem 8 is in part mov
ably inclosed in the standard, vresting upon the
upper end of said spring, and to project above
the upper end of the standard a suitable dis
tance, and this stem carries a forwardly di
rected planar horizontal arm 11% rigidly, the
forward end of the arm having a vertical hol
low body l9 rigid thereon, having preferably a

clude in the device means for permitting its use - delivery spout 215 on and communicating with
in inclo-sing and treating cans of differing di
mensions conveniently, and obviating the neces
25 sity for the employment of a plurality of the
devices for separate use thereon.
Another object of my improvements is to in
clude in the mechanism means for adjusting a
vent-tube and perforater therein to thus equip
30 the invention suitably for use upon cans of dif
ferent diameters, while releasably engaging them
therewith.
These and other improvements to be described,
are treated of in the speci?cation, claims and
35 drawing hereof, but it is to be understood that
various changes may be effected in the device,
in its structures and connections, without de
parting from this invention or the appended
claims.

4.5 opened used in dispensing or evacuating its oil
or other liquid contents, parts being sectioned or
broken away.

The numeral I denotes a circular horizontal
ring base upon which a can to be treated may be
removably mounted, the ring having a radial
55 projection or parallel pair of such projections 2
its upper end.
The lower depending portion of
the body l9 has a ?xed circular ?ange 20
therearound, and a rubber washer, downwardly
concaved, at 2| is seated removably on the de
pending part of said body and stopped by the
ring 20. A little below this washer the termina
tion of body 19 is obliquely shaped and pointed
at 23, and the body l9 has a notch forwardly at
22 just above said beveled edge or cutting
point 23.
The arm l8 has a medial bearing hole 32 in
which is seated movably a pin 25, headed at
the top, threaded at its lower end to seat there
on a nut 28, and a short arm 2i is apertured
to be loosely bracketed on said pin intermediate
the bar It and said nut. A hollow depending
punch 30 has its upper end ?xed in said arm
‘2i, and has a beveled piercing termination 3!.
The numerals 29 and 33 denote respectively a
pair of vertical holes in the arm l8 disposed
at equal distances oppositely from the pin 25,
and to receive alternately the slightly upwardly
directed end of the hollow punch 30, as shown
in dotted lines, whereby this punch may be
employed‘ to punch air-vent holes in can tops
of two different diameters, a pair of such cans
being depicted in dotted lines in Fig. l. The
arm 21 is lowered a sufficient distance when the
pin 25 is pressed down, so that the arm may be
rocked to either hole 29 or 33, and when the
same is registered with either, the pin may be
released, to allow the upper part of the punch

30 to enter and engage the wall of either hole
29 or 33.
'
Referring particularly to said Fig. 2, the nu
meral l3 denotes an upwardly directed eyed
member or ring secured at its lower end to one
side of the standard 8 near it stop and to slid
ably and rockably seat an otherwise free end of
a laterally projecting arm including an annular
part l4 which has an outwardly bent ?nger
piece l5. The numeral l6 denotes an upwardly
obliquely directed bent ?nger ?xed on the oppo
site outer wall of the standard 8, and carries
on its upper end a short coiled compression
spring I‘! whose upper end engages beneath the
15 annular part M tending to rock the latter up
to cant upon the stem 8 above the standard,
to lock therewith frictionally, but releasably.
Within the hollow of the standard 6 the stem
8 has a longitudinal slot 9 therethrough, loosely
20 traversed by a cross pin [0, with bolt-head II
and nut not shown on the opposite end, said pin
also traversing the wall of the standard ?xedly,
and thus to limit the up and down play of the
stem in the standard.
Operation-A closed can, ?lled with oil or
other liquid, as shown in dotted lines in di
ameters of di?erent length, may be seated on the
ring base I. The air vent punch 30 may be if
necessary adjusted to locate it in either arm hole
30' 29 or 33, according to the special diameter of the
can to be treated, as shown in full and dotted
25
lines respectively. Then the operator manually
presses downwardly upon the arm 18, thus caus

to locate these parts within the can, including
the notch 22 in the punch IS. The arm H5 in
descending compresses the spring ‘I in the hollow
40 of the standard 6.
The operator meanwhile also

punches, supporting means upon which they are

relative to a can to be punctured and tapped by

rigidly connected air-vent and spouted hollow
punches, supporting means upon which they are
mounted for punching a wall of a can to be dis
charged of liquid contents, the puncturing ter
mination of the spouted punch having a drain
age aperture opening into the can ?ush with the
inner lower face of its top wall when the can is
inverted and an elastic washer for sealing the
joint of the said punch and can.
3. In a device of the character described,
a rigid supporting member, a terminal spouted

contents, and an air-vent hollow punch on said
member for simultaneously penetrating the can 25
together with the spouted punch, said air-vent
punch being loosely rockably, mounted on said
member endwise, and the member having spaced
seats therealong; with which the latter punch may
be releasably engaged with either to permit said 30
punches to be spaced from each other variably to
operate upon cans of diifering diameters.
4. In a device of the character described, a
rigid supporting member mounted for to and fro
movements relative to a closed receptacle to be 35
tapped, a terminal spouted punch on said mem
ber having a cutter .end for penetrating a can

compressed spring ‘I then recoiling upwardly to
return the arm l8 and its punches to initial po
sitions.
The downwardly concaved washer 2i serves to
60 seal the can around the punch, and the notch
22 serves when the can is tilted su?iciently to
evacuate the contents, to drain out any portion
of liquid which may coat the interior wall of the
can. The device in its forwardly open state may

slot 9 in the stem 8 is long enough to permit the
punches to be used with cans of di?’erent heights
