SAFETY DEVICE FOR CONTAINER MOVING
MACHINERY
Stanley R. Rosendale, Mount Healthy, Ohio, as
signor to The Karl Kiefer Machine Company,
Cincinnati, Ohio, a corporation of Ohio
Application September 16, 1936, Serial No. 101,111
8 Claims. (Cl. 192-150)
I shall describe my invention in connectionwith
means for moving bottles, which may in turn be will be set forth hereinafter or will be apparent
thought of as part of a bottle ?lling machine, it to one skilled in the art upon reading these speci
being understood that these are exemplary only
5 of ?elds of utility for my invention. My inven
tion will be equally applicable, as will be appre
ciated by one skilled in the art, to the handling
and movement of all sorts of containers and to
articles which could be crushed, marred and
10 broken by failure of mechanical means properly
to function.
I shall describe my invention also in connec
tion with star wheel means for moving bottles in
a circular path or for changing the direction
15
of movement thereof. The star wheel in com
bination with guide means is well known; and it
has also been understood in the art that there
was a necessity for some sort of safety means
operative to stop the star wheel if the bottles fail
20 properly to feed into the star wheel spaces, so as
to avoid jamming and breaking of the bottles.
The suggestion of the prior art comprised hinging
a section of the guide and connecting the hinged
section with a clutch located at a convenient
point in the power transmission chain of the
mechanism. This is operative to the end of stop
ping the mechanism upon actual displacement
of the bottles.
It will be clear, however, that it involves cer
?cations, I accomplish by that certain construc
tion and arrangement of parts of which I shall »
now describe the aforesaid exemplary embodi
ment. Reference is made to the accompanying
drawing in which:
Fig. 1 is a top plan View of a means for moving
bottles including a star wheel, guide and con
veyor.

Fig. 2 is a sectional view of the mechanism
taken along the lines 2-2 of Fig. 1.
Fig. 3 is an elevational view of the mechanism
of Fig. 2 (with the conveyor in section), the view »
being taken along the lines 3-3 of Fig. 2; and
15
Fig. 4 is a sectional view of the clutch mecha
nism taken along the lines 4—4 of Fig. 5.
In Fig. l I have shown a simple means‘ for
changing the direction of motion of bottles 5 I
moving along a conveyor 6. A guide means 1
during rotation of the star wheel.
The simple ,
mechanism shown will serve to illustrate the 25
principles of my invention it being understood, of
tain operating disadvantages. When, for differ
course, that my invention is applicable to other
mechanism, and in particular that instead of the
small star wheel shown a much larger mechanism
ent sized bottles or containers it becomes nec
essary to change the star wheel and guide, a new
bottles, as they move about the periphery of the
connection between the hinged section of the
guide and the clutch must be made.
This is a
35 matter of rather delicate adjustment, and the
time consumed seriously cuts down the operating
capacity of the machine. Also the safety mech
anism operates only if a jam occurs at the hinged
section of the guide.
4:0
It is an object of my invention to provide a
safety means not subject to these disadvantages.
It is an object of my invention to provide a
structure in which changing the star wheel and
guide requires no change in or readjustment of
the safety mechanism.
It is an object of my invention to provide a
safety means which is sensitive to and operative
upon the occurrence of any undue pressure
against or resistance to the motion of the star
6 wheel or its equivalent.
It is an object of my invention to provide a
safety device which will stop the mechanism
if a jam occurs anywhere around the circumfer
ence of the star wheel.
'
These and other objects of my invention which
'20.
aligns the bottles so that they may be positioned
in the interspaces of the star wheel, and also
serves to keep thebottles in these interspaces
may be employed in connection with which the ‘
30
Wheel, may be subjected to various treatments,
such, for example as cleaning or ?lling.
Referring to Fig. 2, the star wheel 8 is keyed or ,_
otherwise non-rotatably fastened to a shaft 9 “
which is suitably journaled in the frame ll) of
the machine. A gear I l is rotatably mounted on
the shaft 9 and may be held in position by a col
lar l2. The gear ll meshes with a driving gear,
l3, which through certain transmission means
(not shown) and through a clutch which will
hereinafter be described is connected to a source
of power for the machine.
'
'
A plate I4 is bolted as at I 5 to the gear I I so
as to rotate therewith; and it bears one or more
projecting pins it‘. These pins engage detent
45
means I‘! on a collar I8 slidably splined to the
shaft 9. The engagement of the pinswith the
detent means is the means for transmitting mo
tion from the gear II to the star wheel shaft 9; V50
and the detent means are tapered in form so that
if there is resistance to the movement of the shaft
9 the pins l6 can depress the collar l8 permitting
the shaft to remain stationary in spite of rotation ,
of the gear H.

to have a lost motion connection between the
The collar is held upwardly by a lever 20, piv
oted as at 2| to a bracket 22 on the bed' of the
lever 20 and the end of the bell crank 45.
To
this end, I employ a rod 46, passing through the
lever 20, and having an abutment 41 thereon.
A compression spring 48 engages between the
machine. An end of this lever bears against a
thrust bearing 23 on the collar l8. The other
end of the lever is urged downwardly by a com
lever 20 and another abutment 49 on the rod;
The operation of my mechanism will be clear
from the foregoing; but'it will be understood that
modi?cations may be made in my invention with
pression spring 24 which may be adjusted by
means of a set screw 25, threaded in the bracket
22, or by equivalent adjusting means.’ By'such
means the degree of pressure exerted by the lever
20 can be adjusted so that the sensitivity of the
out departing from the spirit thereof, and that 10
safety mechanism can be made anything desired. ‘ ‘what I claim as new and desire to secure by
Letters Patent, is:
It is desirable to stop the mechanism upon ac
tuation of the safety means, and I- shall now de
scribe the provision made for this purpose.‘ As
15 shown in Fig. 3, a transverse shaft 26. is suitably
.
1. In a safety device‘ of the character described

mounted on said shaft, a collar slidably but non
journaled in the bracket - 22 and in another" rotatably'mounted on said shaftand interen
gagement means on said driving means and on
bracket 21. This shaft bears a pair of arms 28
for operating a clutch. This clutch is shown in
section in Fig. 4. The main operating shaft of the "
~20 machine is shown at 29 and is indicated as bear—'
said collar, atleast one of said interengagement
means being beveled so that relative rotation of
said driving means and said shaft causes ‘dis 20
placement of said collar axially of said shaft,
and means for urging said collar toward saidv
driving means'with a predetermined force, said
means comprising a lever and adjustable spring
means bearing against’ said lever,- a clutch, oper
ing a pulley 30, to which poweris transmitted for
a the machine bymeans of' a belt 3| or otherwise
as may be desired. The pulley is free to rotate
on the shaft but is connected with a clutch part

This clutch part is, operated by the
arms 28 as will be readily understood. The par
ticular form of the clutch is not a. limitation on in motion-transmitting engagement.
2. In a safety device of the character described 30
'30 my invention, and‘ may be any desired. I have’ ‘a shaft to be driven, driving means rotatably
shown a simple form of clutch, having teeth.
The shaft 26, near its other end (as shown‘ mounted on said shaft, a collar slidably but non
rotatably mounted on said shaft and interen
' most clearly in Fig; 2),bears another arm 34. gagement means on said driving means and on
This arm carries a detent 35 adapted to engage
said collar, at least one ofsaid interengagement 35

said driving means and said shaft causes dis-_
placement of said collar axially of said shaft,eand
means for urging said collar toward said driving
wise by suitable means, and to‘ this end I have
provided a rod‘3'l attached to the arm 34 and
passing through the bracket 22. A compression
40 spring 38 engages the‘. bracket abutment 39 on
the rod 31. In the. position of the elements
shown in Fig. 2,,the clutch is' engaged. but it is
means with a predetermined force, said means 40
comprising a lever and adjustable spring means f
bearing against said lever, a clutch, operating »
means for said clutch including an arm, said
arm being located in a position of latching en
gagement with said lever when said clutch is in
maintained in engagement only by the lever 20,
which,’ as before explained, acts as a latch.
45 Should the left hand end of the lever 20 be
motion-transmitting" engagement, and manual
raised (as would happen for example, if the
. collar ,l8 were forced downwardly by the pins 16) ' means for bringing said arm and said lever into
the clutch would be instantly disengaged as will
be clear.
In order to provide for the reengagement of
50
the clutch, an operating lever 40, is attached to
the shaft 26 and'is provided with a handle 4|.
Assuming that power is being. supplied to the
pulley 30, the handle 4! acts as a starting handle
55 for the machine. When it is thrown to the left
in Fig. 2, the clutch is engaged and the arm 34
is latched by the lever 20.
.
'
Should one of the bottles 5 jam in the mecha
nism, the added resistance imposed, on the star
60 wheel 8 will cause the pins 16 to force the collar
18 downwardly, thus releasing the shaft 9 on
which the star wheel is mounted. I, At the same
1 time, however, the collar depresses the rightiha'nd
end’of the lever- 20 and raises the left hand end
.65 of. it, thereby-releasing the arm 34. The action
of the spring 38 is to rock the shaft 26, thereby
throwing outthe clutch.
