11 Claims. (Cl. 93—-5)
My invention relates to crimping the ends of
paper wrappings or tubes for rolls of coins and
other cylindrical objects. Primarily it provides
a device capable of crimping rapidly, securely
5 and uniformly,
It relates especially however to devices for
crimping ?lled coin containers fed to it by hand,
and from this aspect it comprises a crimper head,
a carrier adapted to receive the ?lled container
IO from the hand of the operator and present the
same to the crimper head, and associated mecha
nism to operate the carrier and the crimper head
and to operate these parts in proper time rela
tions. Preferably too the arrangement is such
that the whole operates at whatever rate the
operator is able to handle the containers. The
carrier servesseveral purposes. First, it relieves
the operator of the duty of holding each article
of the work during the actual crimping‘operation,
20 thus saving possible injury to his hands and en
abling him to devote his time to feeding and any
other operations that he may be called on to per
form simultaneously; second, in its preferred
form, it enables crimping to be done simulta
neously with feeding, neither of these operations
therefore delaying performance of the other;
third, it places each and every article in the
proper position with respect to the crimper head
and. permits the use of a device that holds each
package securely against rotation during crimp~
ing, thus assuring proper crimping in all cases.
Preferably the arrangement is such that the
carrier holds the package at rest at the crimping
station and the crimper' head is brought to the
package to make the crimp. Further my inven
tion comprehends also an improved crimper head
adapted to make a crimp faster than crimper
heads heretofore used; while this part of my in
vention is adapted for use with machines wherein
40 the package is held by hand conceivably, it is
especially adapted to machines wherein they
crimping is entirely a machine operation since
it enables the crimping to be done at the higher
rates of which complete machine operation is
., . capable. Other features of my invention appear
hereinafter. In these respects my invention is
not limited to hand fed machines. Also my in-‘
vention is not limited to containers for coins as
will be apparent; but can be employed to crimp
other containers and wrappers also.
The accompanying drawings illustrate the pre
ferred form of my invention as applied to a ma»
chine for crimping ?lled coin packages already
crimped at one end.

crimper head.
The crimper head i is arranged to be recipro
cated toward and from the coin rolls as these are
held by the carrier 3. The carrier is provided
with a number of pockets 4 (in the present in
stance, six pockets) to receive the coin rolls (one 15
roll per pocket), and is movable in such a manner
as to carry the pockets substantially successively
to the crimping station position of Z in Fig. 1,
whereat the crimping is done. Preferably it is
mounted for rotation about an axis 3'! for this 20
purpose. The carrier is so disposed that at least
one pocket is exposed for hand feeding at what
may be called the loading station (at the left hand
side in Figs. 1 and 4). Preferably too the carrier
is moved intermittently, step by step in carrying
the pockets from the loading station to the crimp
ing station; as a result the empty pockets are held
at rest momentarily at the exposed position for
ready loading and also the crimping mechanism
is thereby permitted to be simpler than it would
be if the crimping were done while the carrier
is in motion. As appears at 2 in Fig. l, the work
to be handled by the machine illustrated com
prises coin-?lled paper tubes, the tubes being
crimped previously at their bottom ends (on
which they rest in the carrier) and projecting
somewhat above the coin stack at their upper
ends for crimping in the present machine (as
indicated in broken lines in Fig. 1). The asso
ciatcd mechanism hereafter described drives the
carrier and also reciprocates the crimper head,
so that the‘ two operate in proper time relation.
Arrangements can be made for the automatic
discharge of the crimped rolls from the carrier;
e. g., by arranging for the fall of each crimped
roll from its pocket as the pocket returns from
the crimping station to the loading station as
later described.
Broadly speaking, the crimper head I may be
of any type suitable for the purpose. For ex~
ample, it can be that rotary crimper head here
tofore commonly used which comprises a simple
cylinder 8 to closely encompass the end of the
wrapping, one or two crimper members each hav
ing a curved under surface to receive the edge
of the paper and roll it back on itself internally
of the wrapper (e. g., a wire or wires 9), and a
bridge or cross bar 5 at the same end of the
cylinder by means of which the cylinder is car
ried. A driven shaft iii connected to the bridge
or cross bar 5 serves to support the crimper head
and rotate it rapidly as the head is pressed against
the roll or as the roll is pressed into the head. I
have found however that these prior crimper
heads are not capable of making as satisfactory
crimps as I desire when pressed down against
the tube end sufficiently rapidly to take full ad
ously and a crimp can be made by simply press
ing the crimper head to a tube. The crimper
frame 2i is supported vertically and reciprocated
by mechanism including the connecting links 28
as later described in more detail.
Preferably the carrier 3 consists of a disc-like
vantage of the high operating speed of which
machines of my invention are capable; at least
not unless the head is rotated at unnecessarily
member, the pockets 4 (of suitable size and shape
in cross section to receive the coin rolls stand
ing on end) are pierced completely through it, and
the carrier rests against a frame plate 34 which
thus serves to close the pocket bottoms and pro
vide a support for the rolls during crimping; this
permits ready discharge of the rolls after crimp
ing, the plate 34 being cut away at some point
35 traveled by the pockets in returning from the 15
high speeds; and at such high rotary speeds there
is some tendency for the crimper head to destroy
the integrity of the paper. Preferably therefore
I provide the crimper head with a circumferen
tially-long surface or a series. of surfaces I I curved
upwardly and inwardly to engage the projecting
end of the wrapper continuously or at many points
around substantially the whole of its circumfer
ence, so that the end of the tube is engaged and
turned inwardly at a corresponding number of
the parts of its circumference rather than only
at one or two points as heretofore. This or these
surfaces Ii need not be shaped to turn the end
of the tube back toward the opposite end of the
roll (as do the crimper members 9) ; it is su?icient
if this or these surfaces iI will turn the tube end
inwardly for, say, about 90° as shown in Figs. 2
and 7. If the crimp is to be a rolled crimp as
illustrated in Fig. l, a few crimper members. 9
(say, two) having wrapper-engaging surfaces
suitably curved for this purpose as heretofore
will suffice to turn the tube end back to effect
the roll of the crimp. In so far as these surfaces
of the crimper members 9 are co-extensive with
40 the surface or surfaces I l the two may be at about
the same level; usually however I set the crimper
members 3 so that their working surfaces project
a little from the surface or surfaces. II, i. e., are
disposed to strike the end of the tube slightly in
45 advance of the surface or surfaces I i. Preferably
however the end of the tube is supported extern
ally as by the internal cylindrical surface of the
member 3 as before. Conveniently therefore the
crimper head can consist, as shown, of a mem
50 ber 8 bored to closely encompass the end of the
coin tube or wrapper, this encompassing internal
cylindrical surface blending into the curved sur
face or surfaces I I (Figs. 2 and 7) and the mem
ber being slotted at 52, say at two diametrically
55 opposite points, to receive the crimping members
ii which may be like those heretofore employed.
Preferably one or two holes. I3 are provided (Figs.
'7 and 8) to permit the escape of any fibers that
may be worn from the wrappings or tubes during
the crimping operations.
In order that the crimper head I may recipro
cate toward and from the carrier 3, its support
and driving shaft is mounted in a crimper
frame 2! which, in turn, is mounted for reciproca
the machine frame ‘.23. Preferably it is
65 tion
siidingly mounted on the rotating shaft 22 which
serves to rotate the shaft ill; the upper and lower
ends of the shaft 22 may be supported by upper
and lower parts of the machine frame 23, and
70 have fastened to its upper end a sleeve 24 with
which a gear 25 is slidingly keyed, the latter gear
meshing with a gear 26 fastened to the crimper
shaft it. The shaft 22 may be driven continu
ously, say by a motor 2? carried by the machine
75 frame; thus the crimper head I is- rotated continu
crimping station to the loading station, say at a
point where the pockets come to rest momentarily
due to the intermittent movement of the carrier;
the rolls are thrust from the carrier through this
cut; if the carrier and plate 34 are substantially 20
horizontal, gravity will serve to discharge the
A chute 33 below the cut 35 will serve to
direct the rolls to a receptacle. The periphery
of the carrier disc 3 is pierced opposite each of
the pockets, as illustrated at 32, in order that the 25
clamp 33 may engage the rolls to keep the same
from turning during the crimping operation as
later described. The carrier 3 is driven by its
shaft 31.
Preferably all the operations are controlled by 30
a single cam shaft or controlling shaft 38.
preferably, the operation of the machine is put
under the control of the operator so that he may
advance the carrier 3 as rapidly or as slowly as
he may wish. To these ends the driving shaft 35
22 drives a single-turn clutch 39, mounted on
shaft 38, through the worm 4i) and worm wheel
4|; the latter is rotatably mounted on the cam
shaft 38 but is adapted to be engaged with the
shaft by the clutch. This clutch is controlled by 40
a link 42, connected say to a foot pedal through
the link 43; single-turn clutches are well known,
and no description of that here employed is
needed therefore; as the operator depresses the
foot pedal and link 43, the clutch operates to-en
gage the worm wheel 4! to the cam shaft 38 for
one complete revolution of the cam shaft and
then break the driving connection again so that
the cam shaft 38 comes to rest unless the operator
has held the pedal down or depressed it for a
second time. During a part of each complete
revolution of the cam shaft 38 the latter turns
the carrier 3 the angular distance separating two
adjacent pockets, 1. e. one-sixth of a rotation
in the present instance; this is effected by pro
viding an intermittent gearing between the cam
shaft 38 and a short parallel shaft 44 driving the ‘
carrier spindle 31 through the gears 45; prefer
ably this gearing comprises locked intermittent
gears 46 and 41 which will be understood from
Figs. 5 and 6; cooperating toothed portions on
these gears serve to turn the carrier 3 during a
portion of each revolution of shaft 38 while co
operating curved blank portions thereon lock the
carrier 3 during the remainder of each revolu
tion with one pocket at the crimping station.
Also, a cam 53 on the cam shaft 38 serves to
reciprocate the crimper to bring the crimper to
the roll while the carrier is at rest; for this pur
pose the crimper frame links 28 are connected to
a cross head 54 sliding in the machine frame
(Figs. 1 and 5) and provided with a follower roller
56 to engage the cam; since the shaft 38 and cam
53 are set to one side a lever 55 hinged at one end
to the frame is interposed between the ‘cross head
54 and the follower roller 56 (Figs. 1, 5 and 6).
Preferably the crimper. head I is pressed to the
tube or wrapping yieldingly rather than posi
tively; preferably therefore the roller 56 simply
supports the cross head and associated mechanism
against'the cam, so that as the high point of the
cam passes from‘ beneath the roller the cross head
and crimper can fall; gravity alone may serve to
depress the crimper, but if necessary the weight
10 of the parts can be supplemented by a spring 57
fastened at one end to the frame and at its
other end connected to the cross head, say
through the agency of an interposed lever as
illustrated. As will be observed from Fig. 6, the
15 intermittent gear 46 and the cam 53 are so asso
ciated that a new roll is brought to the crimping
station while the crimper I is held elevated, but
during the period wherein the carrier is locked at
rest with a coin roll at the crimping station, the
20 ‘crimper I is reciprocated down against the end
of the roll to form‘ the crimp and then is lifted
again away from the roll. The clamp 33 which
serves to hold the roll against rotation during
the action of the crimper I, may be a simple slid
25 ing member as illustrated, indented to somewhat
adapt the machine initially for handling a
munber of sizes of coins by providing the crimper
frame 2| with a corresponding number of crimper
heads I, la, lb, etc., and by making the crimper
frame rotatable at the will of the operator. The
crimper heads can be mounted around the frame
2| as illustrated, each being supported and driven
like the crimper head illustrated in section in
Fig. l. The crimper frame 2! may be provided
with indexing means whereby it can be locked 10
with any one of the crimpers in position above
the crimping station; for example, it may have a
plurality of notches 68, one above each crimper,
into which the latch 69 can enter. Thus, by
simply lifting the latch 69 the crimper frame can 15
be turned to bring another crimper Ia, lb or lo,
etc. to operating position.
It will be understood of course that my inven
tion is not limited to the details of construction
and operation illustrated in the accompanying '20
drawings and described above, except as appears
hereinafter in the claims.
What is claimed is:
1. In crimping mechanism of the kind de
scribed, the combination of a crimper head, a 25
carrier for the articles, said carrier having an
span the roll and provided with teeth at its end
to engage the outside of the roll; if necessary, upwardly and downwardly open pocket adapted
teeth 59 may be provided at the wall of the pockets
to receive the articles by movement thereof in
4 of the carrier 3 to engage the opposite sides of a path entirely above the bottom of the pocket
the rolls from. the clamp 33 (Fig. 4). As shown and said carrier having a loading station whereat
in Fig. 1, the clamp 33 can be positioned to engage said pocket is exposed for hand loading, a ?xed 30
the rolls through the peripheral holes 32 in the
plate to close the bottom of the pocket and pro
carrier and thus compress the rolls against oppos
vide a support for an article in the pocket at
ing walls of the carrier and against the teeth 53.
Preferably the clamp 33 is actuated in a yielding said loading station and opposite said crimper
head, the bottom of the pocket being open at
manner; i. e. is moved to its clamping position by another
point to permit the discharge of a
means of a spring 60 so that the clamp without
from the pocket, said carrier also
change is adapted to operate the rolls of various
diameters; one end of this spring being ?xed to being movable to carry the articles to be crimped
along said plate from said loading station to po~
40 the frame, the other end can engage for example,
for crimping, and associated mechanism to 40
a pin on the'lever Bl by which the clamp 33 is
reciprocated. A face cam 62 on the cam shaft 38
is arranged to engage with the follower roll 63 on
the lever 6| to withdraw the clamp 33 from each
roll, say just after the crimper l is raised from
a roll, and to allow the clamp spring 6|] to press
the clamp 33 against the next roll just before the
crimper comes down into engagement with the
roll and while the crimper is acting.
The operation of the machine illustrated will
be understood from the foregoing. In brief, the
operator stands each tube of coins on its already
crimped end in a pocket 4 of the carrier 3, rest
ing on the frame plate 34. He then depresses
.55 his pedal, and consequently the carrier 3 is
stepped around su?iciently to bring a new pocket,
and presumably a coinroll, to the crimping sta
tion and then the carrier comes to rest.
clamp 33 then operates to press against the roll
60 now at the crimping station, and the crimper I
descends, rotating, makes the crimp and returns
to its position in Fig. 1.
As the result of the
same movement of the carrier a roll previously
?nished was brought above the opening 35 in
65 the frame plate 34 and fell therethrough into the
chute 36. The operator may depress the foot
pedal as rapidly as he can feed rolls to the carrier;
the operating rate depends therefore only on the
handiness of the operator.
After rolls of one size of coin have been han
dled, rolls of another size can be handled by sub
stituting another carrier plate 3 provided with
pockets 4 suited to the .new size of coin, and by
substituting a proper size of crimper l for the
75 crimper previously used. Preferably, however, I
operate the crimper head and the carrier.
2. In a crimping mechanism of the kind de
scribed, the combination of a continuously oper
able crimper head to inturn and crimp an end
of the side wall of each article, a carrier for the 45
articles, said carrier having a loading station
whereat the carrier is exposed for hand loading
and being movable to carry the articles to be
crimped from said loading station to a crimping
station adjacent said crimper head, and means 50
operable by the operator each operation of which
causes the crimper head to make one crimp and
the carrier to advance a single de?nite step to
bring an article to the crimping station, the ad
vancement of the carrier another such step then 55
awaiting another operation of said means by the
3. In a crimping mechanism of the kind de
scribed, the combination of crimper means to in
turn and crimp upon itself an end of the side 60
wall of each article, a carrier provided with a
plurality of pockets for the articles to be crimped,
said carrier being exposed at a loading station
for hand loading and said pockets being succes
sively arranged in said carrier so that one pocket 65
stands at said loading station for loading while
another pocket stands at a crimping station ad
jacent said crimper means, power driven means
to actuate said crimper means and to advance
said carrier, and means operable by the operator 70
each operation of which connects said power
driven means to the carrier and crimping means
to advance the carrier one de?nite step to bring
an article to the crimping station and make one
crimp, the advancement of the carrier another 75
such step then awaiting another operation of
the last mentioned means by the operator.
4. In crimping mechanism, the combination of
a rotary crimper head, means to rotate the crimp
er head continuously, a carrier having a loading
station whereat the carrier is exposed for hand
loading while the carrier is at rest and the crimp
er is making a crimp on an article previously fed
to the carrier, said carrier being movable to carry
10 the articles from the loading station to a crimping
station, associated mechanism to move the crimp
er head to and from the articles at rest atthe
crimping station to make the crimp, and to ad
vance said carrier intermittently, and means con
trolling said associated mechanism actuatable by
the operator each operation of which causes said
associated mechanism to advance said carrier one
de?nite step to bring an article to the crimping
station and make one crimp, the advancement
.20 of the carrier another such step then awaiting an
other operation of said controlling means by the
crimping station to make a crimp while the car—
rier is at rest and to return the crimper head
