Application July 26, 1937, Serial No. 155,740
4 Claims. (Cl. 101-39)
My invention relates to can markers; and the
broad object of my invention is to provide a
marker for cans which may be set to mark a can
at any desired point along its periphery as the
‘5 can travels through a chute.
The invention possesses other objects and fea
tures of advantage, some of which, with the fore
going, will be set forth in the following descrip
tion of my invention. It is to be understood that
I do not limit myself to this disclosure of species
of my invention, as I may adopt variant em
bodiments thereof within the scope of the claims.
Referring to the drawing:
Figure 1 is a side elevational view of a can
15 marker embodying the improvements of my in
vention; and
Figure 2 is a front elevational view of the same.
Figure 3 is a vertical sectional view of the
marker, showing details of the marking wheel
20 and can guiding devices; and
Figure 4 is a detail sectional view of the mark
ing wheel and its mounting.
In terms of broad inclusion, the can marker
embodying my invention comprises a marking
25 wheel, means for guiding the can past the wheel,
and means for adjusting the wheel relative to the
The can is preferably guided so that its
axis remains in substantial parallelism with the
axis of the wheel, and the adjustment is ef
30 fected by shifting the wheel axially of the can.
The marking wheel is also preferably mounted
in a chute along which cans to be marked may
pass, and means are preferably provided for feed
ing the cans, one at a time, past the marking
5 Wheel.
In greater detail, and referring to the draw
ing, the can marker comprises a main chute
2 along which a plurality of cans 3 to be marked
may pass. A housing 4 is mounted on the lower
40 end of the chute and forms a continuation of
the latter; the lower end of the housing or chute
extension 4 having an opening ‘6 through which
the cans may be discharged. A marking wheel
1 is provided in the chute for marking the cans,
45 and is held by a hub 8 slidably mounted for ro
tation on a hollow shaft 9 journaled in the hous
ing portion 4 of the chute. The wheel is rotated
by a pulley || mounted on a projecting end of
the shaft 9.
Means are provided for adjusting the marking
wheel relative to a can.
For this purpose a rod
|2 extends through the hollow shaft 9, and car
ries a pin I3 projecting out through the shaft
9 and hub 8 for engaging a socket M in the
55 wheel ‘I. In order to allow for shifting the wheel,
a slot I6 is provided in the shaft through which
the pin |3 may project. The rod I2 is moved ax
ially by a manually operable lever ll having a
slot IS in its upper end for engaging the rod. A
pivot mounting is provided for the intermediate 01
portions of the lever by a short rod I9 slidably
journaled in a bracket 2|, to which the lever I1
is connected by a pin 22.
The lower end of lever H is held in a selected
position by a plate 23 having a series of lever 10
engaging notches 24. In order to hold the lever
in a selected notch, and also allow shifting of the
lever from notch to notch, a spring 26 is com
pressed between a pin 2‘! on pivot rod I9 and
the bracket 2|. By this arrangement the mark 15
ing wheel I may readily be shifted along the
shaft 9.
The marking wheel is circular in shape and
has a type carrying strip 28 mounted on its pe
riphery. This strip is inked by a suitable ink 20
ing roll 29. Since it is desirable to quickly re
place the marking wheel with another having
different type, my wheel is provided with a pe
ripheral recess or notch 3|, so that the wheel may
readily be slipped on or off the shaft. In order
to releasably hold the wheel on the shaft, a pair
of spring pressed elements 32 are provided on
the wheel for engaging behind the side of the
shaft facing the notch 3|. As shown in Figure
3, the wheel notch 3| is arranged on the side op 30
posite the pin engaging socket I4.
Means are provided for feeding the cans, one
at a time, past the marking wheel. For this pur
pose a star wheel 33 isjournaled in the chute
extension 4 adjacent the lower end of the main
chute 2 for the purpose of retaining the cans in
the chute above the marking wheel. The star
wheel is controlled by an arm 34 pivoted on the
lower end of the chute portion 4 so that the arm
lies under the opening 6. A spring held bar 36
connects this arm with a plate 31 slidably mount
ed adjacent the star wheel and carrying a pair
of lugs 38.
As shown in Figure 3, the lower lug 38 engages
an arm of the star wheel to hold the column of
cans above the marking wheel, but when the con
trol arm 34 is depressed by a can dropping
through the opening 6, the lower lug 38 moves
down to release the star wheel. The wheel now
rotates until the next arm moves around against 50
the upper lug 38, and is held until the control
arm 34 snaps back in place, whereupon the upper
lug releases the wheel and the latter takes an
other eighth turn. This quarter revolution of
the star wheel allows one of the cans to drop 55
downwardly toward the marking wheel. In its
final position the star wheel again lies in the nor
mal position shown in Figure 3, ready to feed
another can to the marking wheel.
Means are provided for guiding the cans past
the marking wheel, and for pressing the cans
against the latter.
This is accomplished by an
arcuately shaped bar 4| carried by rods 42 pro
jecting through the sides of the chute housing
10 and held by tension springs 43.
The cans are
also held in alignment with the marking wheel
by a pair of disks 44 mounted on the shaft 9,
one on each side of the Wheel 1.
In order to time the can movement with that
of the marking wheel, a ?nger 46 is pivotally
mounted in the housing in the path of movement
of the cans.
This ?nger rides on a cam 41
mounted on the shaft 9, and when the ?nger
moves inwardly on the ?at portion of the cam
20 it releases the can so that the latter contacts the
wheel at just the right time.
I claim:
1. A can marker comprising a marking wheel,
means for guiding a can past the wheel with the
can axis substantially parallel with the axis of
1e wheel, and means for shifting the Wheel
axially of the can.
2. A can marker comprising a shaft, a mark
ing wheel slidably mounted for rotation with the
shaft, means for guiding a can past the wheel,
means on the shaft for holding the can in align
ment with the wheel, and means for shifting the
wheel along the shaft, said aligning means being
freely spaced from the wheel to allow shifting
of. the latter.
3. A can marker comprising a shaft, a marking
wheel slidably mounted for rotation with the
shaft, means for guiding a can past the wheel,
means for shifting the wheel along the shaft, and
means for locking the wheel in a selected posi 15
tion on the shaft.
4. A can marker comprising a hollow shaft, a
marking wheel having a notch therein to allow
positioning thereof on the shaft, releasable means
for holding the wheel on the shaft, a rod extend 20
ing through the shaft, a pin on the rod and pro
jecting through the slot and into the wheel, and
means for moving the rod to shift the wheel along
the shaft.
