from the position which is occupied by the re

_
A web Joining and cutting mechanism is shown
as having been moved to a web joining and cut
' ting position, which mechanism comprises‘a web
de?ecting frame 32, having a brush 33- mounted
thereon, and a cutter frame 34 having a cutter
blade 35 mounted at the lower end thereof, each
of which frames are pivotally movable preferably
about the. same axial center. -In the mechanism
- shown, the pivotal mounting for said frames in
cludes a sleeve 35, carried by bearing brackets 31
depending from the machine frame, upon which
the'cutter frame 34 is mounted. A shaft 38 is
carried by the sleeve 35 and the web de?ecting
frame 32 is'?xed to said shaft.
The description of the detail structure regard
40 ing the above named mechanism will be found in
the aforementioned application,‘ Serial Number

raised position. Before the final web joining and
cutting operations are performed, the attendant

handle 5|, formed at the lower'end of the lever
39, and the free end of the bell crank 45, to there 25

draw the end of the rod'42 from a. slot 49. The.
said lever will then be free to be swung upward
until the plunger rod engages another slot 49
which will thus support the lever in a substan 30
tially horizontal position (see'Figure 20) .
When '
in this latter location the lever is in a convenient
position to swing the frames forward for a ?nal
web joining and cutting operation.
Another rod 52 is slidably mounted in a lug 35
53, projecting from the lever 39, and in the handle
5|, and has a spring 54 compressed between a

in the stationary supporting bracket 31, and is
biased into engagement with the recesses by a
spring 39a. A handle 49 secured to the shaft 38
provides means for releasing the pawl 34a.
‘After a running web roll 3i has been reduced
nearly to exhaustion, the reel is rotated to move
the running web W into the path of the web
de?ecting and cutting mechanism and the web

‘moves the ?apper lever 63 into the path of the
projecting head I28 on the bolt I22, and when
they engage, the bolt I22 is moved outward until
the ?apper lever 63 engages a stop-lug I31,
formed at the upper end- of the clamp supporting
bar 19. As the bolt moves outward, the pin I33
acted upon. In Figure 6, the clamping mecha—
nismis shown in a vertical position on the roll
and they cam ring is shown as closing the switch
92 which will cause the latch to be released.
Upon the release of the latch, the attendant will
65 then be permitted to pull the hand lever 39
downward to swing the web de?ecting frame for
ward against the running web, in time to meet
the approaching adhesive portion on the replace
ment roll, to make a join therewith. '

In moving the web de?ecting frame forward,
the ?apper lever 63a willmove directly into the
path of the bolt I88 on the clamping device and
will be engaged by same during the rotation of the
web roll.

The impact of the bolt against the ?apper lever

It is obvious from the foregoing description of
the clamps that a decided improvement has been
made in the method of clamping the web end of
a web replacement roll to the body thereof.

Referring now to the electrical diagram, Fig
ure 20'shows'a circuit that may be traced from
one‘s‘ide of the line marked (LI) through nor
mally open é‘switoh 51, conductor I4I, latch sole
noid II1,- conductor I42, to one contact ring I43.
Also from the other side of the line marked
(L2) to a second contact ring I44. - This will
bring a source of current to the rings I43, I44
whenthe switch 51 is closed. The said rings
may be mounted in any convenient manner at
the axis of the reel 25 and will rotate with said
reel. Brushes I40—I40, joined to the lines L2
and I42, engage the contact rings I43, I44.
On each arm of the reel 25, a mercury switch
15 I45 is mounted in such position as to close a pair
of contacts I39—I39 when the replacement roll is
in a web joining position and is connected in
series with a cam actuated switch 92.
The cir- ,
cuit which connects said switches I45 and 92
20 with the current supply, is traced from ring I43,
through conductor I46, then through‘ switch I45,
line I41, switch 92 and line I48, to the ring I44.
Assuming that the parts are in the position
shown in Figure 20 and the attendant has closed
25 the switch 51, while pulling downward on the
hand lever 39, the latch releasing solenoid II1
will then be energized as soon as the cam por
tion on the ring 89 engages the finger 9| to, close
the switch 92. Immediately upon the release of

in Figure 22 and comprises a treadle arm I66
pivotally mounted on a support I6I, which arm
has a connecting link I54a to connect same with
the de?ecting frame 32 as shown in Figure 21.
A switch I62, mounted upon the base of the support, has an actuating lever I63 extending from
one side thereof which is adapted ‘to throw the

The means for actuating said lever I63 com

foot pedal I65, which button rests upon one arm
I66 of a bell crank and is normally held in a
raised position by the action of a spring I61 at_
tached to another arm I68 of said bell crank.
A bar I69 has one end joined to the lower end
of the arm I68 and is guided by means of the
engagement of a pin I1I within a slot I12 in said

When operating the web de?ecting and cut

of the above described .type} it is only necessary
for an attendant to place one foot on the pedal
I65, which action will closev the switch I62
through the movement of the bell crank and bar
when the button I64 is forced downward. Hav
