3 Claims. (Cl. 271—1)
This invention relates to an article forming
‘machine, and more particularly to feeding mech
anism for paper bottles.
Among the principal objects which the present
5 invention has in view are: To automatically con
trol anti-jamming of parts of articles being as
sembled; to restrain further feeding of the du
plicate parts to the one jammed; to avoid injury
to the machine; to provide for ready return of
10 the machine to operation;' to make it obvious to
the operator when a part is jammed; to secure
simplicity of construction and operation; and to
obtain other advantages and results as may be
brought out in the following description.

40 used in operating the different parts.
As seen in the drawings, let it ?rst be said that
such part of a container-assembling machine as
enters into the construction and operation of
the particular invention herein involved has been
45 shown. Such machines provide suitable frame
work or bed structure 15 on which is mounted a
rotating head or article carrier I6 having a plu
rality of holders or dies I‘! which are brought suc
cessively into alinement with a plunger’ la. The
50 successive dies 11 have a part of the article to
be assembled inserted therein before said die
comes into alinement with the plunger, and as
here shown, the part 19 of the article inserted
in the successive dies is ‘the side or cylindrical
55 part of containers, such as paper milk bottles.
An instrumentality is provided for automati
cally positioning another part of the article,
namely, the bottom 20, crosswise in front of the
end of the plunger to be actuated by the plunger
[8 and forced into the end of the other part 19 O
of the article. The present invention relates
more particularly to the said instrumentality, and
for convenience in the description thereof, the
part of the article being fed thereby will be re
ferred to merely as a disc, without implying any 10
limitation as to, circumferential shape, surface
or other formation.
The several discs 20 are supplied in stacks as
shown in Figure l, ?atwise against each other in
axial coincidence, with suitable pressure means, 15
such as the weight-actuated rider 2!, for forc
ing the stack axially each time a disc is removed.
The discs are .removed one at a time from the
forward end of the stack by sliding such disc lat
erally from the stack. The above-mentioned in- 20
strumentality accomplishes this operation,’ ef
fecting the removal of the disc from the end of
the stack, a lateral transition and placement of
the disc in the path of the plunger. As here
shown, said instrumentality comprises a platelike guide member 22 the plane of which is nor
mal to the axis of the stack of discs so that the
forward end disc will rest ?atwise against said
member near one end thereof (for convenience
referred to as the upper end of the member).
The said member is of a length more than two
diameters of‘ the discs, thereby enabling a disc to
be moved laterally from the stack to- a position
at one side of the stack but still facing in the
same general direction and in facial contact with
said member. An imaginary center line of said
member will intersect the axis of the aforemen
tioned plunger It. The parts are so arranged
that the axis of the stack and the axis of the
plunger are parallel and spaced from each other
more than a distance of one diameter of the discs
20. Thus there will be no overlapping of the
discs remaining in the stack and the end disc
which is moved laterally to its new position in
axial coincidence with the plunger.
As shown, for instance in Figures '7 to 11, the
said plate-like guide member 22 is provided with
a foot 23 thereon by which said member is
mounted in stationary position upon the bed 15
of the machine. The opposite faces of said mem- 50
her are recessed longitudinally to provide the‘
track construction.
Noting particularly Figure
'7, it will be observed the member provides side or
marginal ribs 215 of a depth substantially that of
the thickness of a disc 20 to be fed. On the other 55
or outer side of said member are edge or marginal
under-cut ribs 25 for receiving and retaining a
plate-like positively actuated slide 26 forming a
part of what may be termed the actuator 21.
This actuator also includes as part thereof a
plate-like releasable slide 28 parallel to the said
positively actuated slide 26, spaced therefrom by
the intervening thickness of the guide member 22
and both said slides being ?atwise slidable upon
10 the opposite faces of the intervening part of said
In normal operation, both said slides
reciprocate simultaneously. Both said slides are
provided with disc openings, the inner or releas
able slide having an opening substantially the
15 diameter of the disc for an upper semi-circum
ference, and therebelow extending to the end of
the slide. The outer or positively actuated slide
is shown with an opening somewhat more than
the diameter of the disc for an upper semi-cir
20 cumference, and therebelow extending to the end
of the slide. ‘This larger size of opening in the
outer slide is to pass the disc therethrough with
out any engagement of it en route. The opening
in the inner or releasable slide is for purposes of
2.5 receiving the end disc with a measure of accuracy
and pushing it downward in the guide member.
The open end for this opening permits the slide to
retract to its upper position and leave the disc in
the lower position to which it has been pushed.
Means are provided for obtaining a releasable
actuation of the disc-engaging or inner slide 28,
so that in event a disc becomes jammed, as illus
trated in Figure 10, the positive actuation of the
outer slide 26 is not communicated to the inner
35 slide until the fault has been corrected by the
operator. For this purpose, the upper end of the
passing the disc therethrough, and a lower open
ing 31 through which the plunger l8 may pass.
The upper opening 36 has its upper half curved
substantially on a semi-circle, the center for
which is coincident with the axis of the stack.
Its lower half is upon a semi-circle or otherwise,
to off-set the same from coincidence with the
disc perimeter thereat. From this lower enlarged
opening edge, in the plane of the face plate,
project two spaced retainers 38 directed in a
radial direction with respect to the opening and
projecting to substantially a distance to lie upon
a theoretical continuation, shown by dot and dash
line 39, of the semi-circular upper opening upon
the same center of curvature. The end disc is 15
thus fed through this face plate in contact with
the upper semi-circular part of the opening of the
plate and having a lower contact only with the
ends of said retainers 38. This limited engage
ment not only augments the action to pass the
disc into the slide opening, but renders it both
possible and probable that the disc, if still en
gaged partly upon the retainers when the down-,
stroke of the slide begins, will snap off of-the
retainers into proper position in the slide opening.
Reciprocation of the positively actuated slide
26 is effected by a crank arm 40 having a slot
4| longitudinally thereof taking over a stud 42
on the slide. The other end of said arm is fast
upon a yoke 43 rotatably mounted on a shaft 44. 30
The opposite end of the yoke is fast with re
spect to a clutch member 45 in turn engageable
by a cooperating clutch member 46 splined upon
said shaft so as to rotate therewith but slidable
for permitting the clutch function to be per 35

ried by a rider 49 in turn operated by a cam 40
between the two slides extending cross-wise of
‘ill the slides, and a parallel yoke 33 extending across
the inner face of the releasable slide. As clearly
shown in Figure 6, this yoke is provided with
holes 3| directed toward the slide, and in these
holes, at their ends next the slides, are balls or
other engaging means 32 pressed toward the slide
by springs 33 in the holes in turn adjustably
tensioned by screws 34 protruding from the outer
ends of the holes. The slide is conveniently pro—
vided with depressions into which the balls or the
50 like will snap while the slides are in normal posi
tion and operation, the depressions, with the
holes and spring tension affording ‘the requisite
frictional engagement for actuating the releas
able slide from actuation of the positively actu
55 ated slide. However, should a disc jam, the
releasable slide encounters enough additional
resistance thereby to effect release of the fric
tional engagement, and thereupon remains quiet
even though the positively actuated slide con
60 tinues to reciprocate. The upper end of the inner
slide therefore remains outward, and the operator
readily notices it, and can stop the machine to
overcome the di?iculty.
I have discovered that one outstanding cause
for jamming of the machine arises fromv failure
of the discs to properly enter the opening in the
releasable slide 28. I have overcome this prob
lem by reducing to a minimum the edge engage
ment of the discs with the ?xed support thereof
where passing the guide, and particularly at the
part of the perimeter of the disc at the front
thereof when slid.
As shown, I provide a face
