The device of the present‘ invention is par- , posed magazine l8, consisting of a pair of rigidly 5
ticularly useful in the packaging of collapsible
articles. Although the device is described herein
‘connected spaced members 29 and 2|, having
opposed slots 22 and 23, respectively, de?ning a
in conjunction with the packaging of thin, tubu-lar, rubber articles, closed at one end, with the
passage 24 for receiving tubular wrappers. from
a feed tube l9, communicating therewith through
10 side walls thereof rolled upon themselves to a
point adjacent the closed end wall, it is not intended that it be so limited for the invention
can be used for packaging numerous other types
of articles. The wrapper for the article is pref-
.an opening 25 in the wall of the member 2|.‘ The 10
lower extremities of the slots 22 and‘23 terminate
in arcuate walls 26 and 21-, respectively, which
serve to, support opposite ends of the lowermost
wrapper disposed in the passage 26. Adjacent
15 erably an open ended tubular member relatively
smaller in diameter and axial length than the
the lower ends of the slots 22 and 23 the mem- 15
bers 2i! and 2| have elongated vertically extendI
diameter of the article so that when the article
and wrapper areassembled a portion of the
article extends beyond the ends of the wrapper.

in which is mounted a reciprocating slide 58.
A bolt 5| threaded through the slide 58 and ex
tending through the slot 48 operatively connects
the slide to suitable reciprocating means to be
described. Secured on the upper surface of the
slide 58, by means of bolts 52, is a block 53 hav
ing formed on one end thereof a plurality of
outwardly extending spaced lugs 54 havingvse
ID are a pair of spaced bearings ‘I5 and ‘I6 hav~
ingjournalled therein a cam shaft 'I‘I upon which
is keyed a spiral cam element ‘I8. The spiral
cam "I8 islpositioned on the shaft 11 below the
slot 48 and has formed therein a groove ‘I9 in
which rides a cam follower 80 freely mounted on
the end of the bolt 5|. Reciprocation of the
slide 58 together with the transfer ?ngers car
ried thereby is actuated by the cam 18, one revo
lution thereof effecting a complete reciprocation 10
cured therebetween a pair of .opposed elongated
transfer ?ngers 55 and 56. 'The ends of transfer
?ngers 55 and 56 during their reciprocatory - of the slide 50. The shaft ‘I1 also has cams 8| and

the same and thereby move the upper surface
thereof into and out of engagement with the lower
I2 through the opening I‘I, grip an article dis
posed therein and withdraw it from the recep
tacle and deposit the same within the wrapper
in the magazine I8.
Mounted on the bed frame Illin the path of
the reciprocating transfer, ?ngers 55 and 56 are
longitudinal spaced opposedv rollers 51 and 58
which cooperate to close the space between the
transfer ?ngers when the ends of the ?ngers
are at the extreme end of their outward stroke,
thereby causing the ?ngers "to grip the bottom
article of the stack disposed in the receptacle I2.
The rollers, in operation, are effective to- main
tain the ends of the' ?ngers in gripping relation
with the article during the return stroke of the
?ngers, and to cause them to release the article
30 before the end of the stroke is reached to permit
the removal of’ the wrapped article from the mag
azine I8 and the positioning of another wrapper
in the magazine prior to the succeeding outward
su'rfaceiof the arm 68, during predetermined por
tions of a single rotation of the shaft 1].
The
cam 82 is so positioned on the shaft ‘I’! as to be
engaged by the cam follower 63 carried on the
lower end of the slidable block 68. The cam 82 20
is so formed and positioned on the shaft 'I'I that
the roller 58 actuated thereby urges the transfer
?nger 56 toward the ?nger 55 on the return
stroke of the ?ngers, releasing the ?nger 56
just prior to the end of the return stroke thereby
releasing the article between the ends of the
?ngers 55 and 56. The release of the article by
the ?ngers is so timed that the article is deposited
within a tubular wrapper positioned within the
magazine I8.

GU lower surface of the member 84.‘ The upper sur
face of a pivoted plate ‘I4 is adapted to'be moved
under the lower surface of the arm 68 when the
samehas been moved to its ‘uppermost position
against the compression of‘ the spring 38 by the
roller ‘I3 engaging withthe member ‘64, and holds
it in said elevated position until the plate ‘I4 ‘is
moved out'of position by means of a cam, to be
described, engageable with the lower end thereof.
Upon release of the plate "I4 from the arm 68
the plunger 35 is moved downwardly by spring‘
36 thereby positively moving a- tubular wrapper,
which has been fed into the passage 24 while the
plunger 35 was held in its uppermost position, past
the inner ends of the spring members 32 and 33.
"is Supported beneath the top of the bedv frame
uously rotating, and at the beginning of a cycle 60
of operation, the slide 50 and the transfer ?ngers
55 and 56 carried thereby are at the extreme
right, as viewed in Figure 2. Rotation of the
cam ‘I8 moves the slide to the left causing the
transfer ?ngers 55 and 56 to traverse the maga 65
zine I8 through the openings 28 and 29 and a
tubular wrapper aligned therewith, and enter the
receptacle I2 through the opening IT, The ends
of the ?ngers 55 and 56 are open as they enter
the receptacle ' I2 and positioned, respectively, 70
above and below the article disposed on the base
I 5. As the slide has been moving on its outward
stroke the cam roller "I3 carried therebyhas raised
the member 64, which through arm 51, link 69
and_pin connection ‘I8, raises the plunger 35 in 75
3
2,134,046
passage 24, so that a tubular wrapper may be
introduced into the passage 24 from the feed tube
l9. When the plunger 35 has reached its upper
most position cam 8| comes into play to pivot
plate 14 and bring the upper surface thereof un
der the arm 68 thereby holding the plunger in
its raised position against the action of spring 36.
At this point, which is the end of the outward
stroke of the slide 58, the cam 82 acts through
10 the follower 63, slide block 60, and roller 58 to
move the ?nger 56 towards the ?nger 55.
This
movement of the roller 58 causes the ends of the
transfer ?ngers 55 and 56 to grip the edge of the
article. The cam 18 then starts the return stroke
15 of the slide 50, during which movement the cam
82 maintains the ?ngers in gripping relation with
the article. The ?ngers draw the article from
the receptacle l2 and into the tubular wrapper
disposed in the magazine. Just before the slide
20 has reached the end of its return stroke the cam
82 permits the roller 58 to drop, thereby permit
ting the ?ngers to open and release the article.
The release of the article by the ?ngers is so
timed that the article is substantially centered
25 within the tubular wrapper. Immediately fol
lowing the release of the article the disk 83 has
moved around to bring the notch 85 of the ?nger
84 carried thereby into position to remove the
wrapped article from the magazine. Upon the
30 removal of the article from the magazine the
cam 8| moves the end of the plate it out of en
gagement with the under surface of arm 68 there
by releasing plunger 35 whichis urged down
wardly by spring 36 to project a wrapper past the
35 ends of the spring members 32 and 33. The de
vice is then in position to repeat the foregoing
cycle of operation.
Having thus described the invention what I
desire to obtain by Letters Patent is de?ned in
the appended claims. '
