to secure the desired squeezing action of the
Oneobject of my invention is to devise a cas
ing stripping machine having a mechanism
=10 adapted to feed the casings to the cooperating rolls
thereof, a portion of the mechanism being oper
atively associated with
a
crushing
machine
‘whereby'the casings are automatically delivered
from the latter machine to the mechanism and
r15 thence to the stripper without‘ requiring manual
intervention of any kind.
,
A further object is to provide a machine of the
character indicated in which the feeding mech
anism' de?nitely ‘grips‘the casings during their
120 passage to the stripping machine and‘ retains
this grip until the casings are caught by the
cooperating stripping rolls.
‘ A further object‘is to devise an attachment
for a stripping machine comprising a conveyor
25 which transmits the casings singly from the
' crusher to the stripper and‘ a mechanism which
cooperates ‘with the conveyor to grip the casings
in advance of their reaching the stripping’rolls
to thereby insure that the casings will be car

‘
‘
‘ A further object is to provide a stripping ma
chine in which the centered portions of succes
sive casings are fed between the strip-ping rolls
intermediate the ends thereof and the “trailing
35 portions of the casings are carried across the
breast of the rolls while being drawn therebe

In the drawings:
' .Figure 1 is a sideelevation of my improved
casing stripping machine.
‘ 'rFigsy2 and 3 are plan and end views of the
machine, as viewed in the direction of the an
50 rows 2 and. 3 in Fig. 1, respectively.
Fig. 4 is a section along the line‘ ll—-4 in Fig. 3,
looking in the direction of the arrows, and’ show

and the shaft which carries the distributing rolls.

casings while being drawn therebetween.
,
The shaft on which the roll I2 is mounted ex
tends outwardly of the standard II and has 10
secured thereto a pulley l4 that maybe driven
in any approved manner. The sameshaft‘ has
also secured thereto a gear- l5 which ‘meshes
with. a gear l6 secured to the shaft forming a
part of the roll l3, thereby insuring that the 00- ‘15
‘operating portions of the squeezing ‘rolls'will
rotate in the same direction. The squeezing rolls
possess the same diameter and are driven at the
same rotative speed, so that the indicated co
operating portions thereof will also move at the 20
same speed and hence will prevent any dragging
action of the rolls on the casings while being
drawn therebetween.
'
e
'
An annular channel ‘I1 encircles the squeezing
roll I 2 intermediate the ends thereof‘and oper- 25
ating in this channel is an endless belt. l8 which
also‘ passes over a pulley I!) that is preferably
carried by a frame 20 forming part of the usual
crushing machine 2 |.' This machine, is provided
with the customary feeding rolls ‘22 and 23,“and 30
also a crushing roll 24. The purposeof provid
ing the pulley 19 on the crushing machine‘ is to
eliminate manuahh‘andling of ‘ the casings while
being transferred from thelcasing machine to
the stripping machine, the casings being depos- 35
itedon the belt l8 as they issue from’ between
the feeding and crushing rolls 23 and 24, respec
tively, and being thereby automatically carried
to the squeezing rolls l2 and, l3.
.
‘
An annular‘ channel ‘25, similar to the chan- 40
nel I1, encircles the roll 13 in substantial regis
tration with the channelell, and operating in
the channel 25, butvonly contacting the upper
and lower portions of ‘the roll I3, ‘as clearly shown
in'Fig. 1‘, is an ‘endless belt 26 which, at one 45
end thereof passes around an ‘idler pulley 21 that
. is mounted on a shaft 28 carried in a‘p‘air' of
standards ‘29‘which extend upwardly from the
tank 40.’ The opposite end of the ‘belt 26 passes
around an idler pulley 30 that is mounted‘ on a 50
shaft 3| carried by a. pair of standards 32 pro
vided on the‘frames l0 and ILrespe‘ctivelY.

portion 33 which serves to direct, in connection ' frictional drag which, in conjunction with the
with a guide 34, delivered casings on to the usual
collecting hook 35. The lower disposition of the
pulley 30 also insures that the belt 26 will con

of the upper squeezing roll to insure such a de
gree of frictional contact therewith as will effect

down onto the usual collecting hook 35 and the
trailing portions of each casing are deposited into 10
>
This frictional drive of the belt 26 is somewhat
enhanced by a rather close contact of the ad
jacent portions of the belts 26 and I3, as shown
in Fig. 1, it being understood that this contact is
not so intensive, in conjunction with the natural
15 sag of the upper portion of the belt I8, to prevent
casings that are being carried by the upper por
tion of the belt I8 from passing between the
cooperating portions of the belts I8 and 2G.
The gear I5 also meshes with a gear 36 that
is ?xed to a shaft 31 which is rotatably mounted
in and extends between the uprights I0 and II.
Accordingly, the shaft 31 and the lower squeezing
roll I2 will rotate in opposite directions, the roll
I2, for example, rotating in a clockwise direc
25 tion, while the shaft 31 rotates in a counterclock
wise direction. A pair of tapered, distributing
rolls 38 are ?xed to the shaft 31 on opposite sides
of the belt I8, respectively (see Fig. 2), and op
erating in conjunction with these distributing
30 rolls is a V-shaped guide frame 39 whose ends
are outwardly extended for support in the stand
ards I8 and II. The closed end of the frame
39 is located somewhat in advance of the pulley
21 for a purpose presently explained.
Since it is contemplated that my improved at

tions across the breast of the squeezing roll I2
and hence prevents any entangling of the indi
cated casing portions with following casings.
After being delivered through the squeezing
rolls, the intermediate part of each casing falls

of the annular channels I1 and 25 bears such
a relation to the thicknesses of the belts I8 and
26 that the squeezing surfaces of the rolls I2 and
I3 are substantially continuous.
