Both of the spiders can be moved along in the 68.‘ The‘ particular construction of‘ parts at this
same direction for side register by leaving them end is adapted for installation with the parts of
both connected. This is a useful feature as it an automatic pasting machine, particularly for
30 occurs some times that a fractional width roll the automatic paster, which is the subject matter
on one side of the press for one edition has to be
run on the other side of the pres." for the next
edition. Heretofore in such a case it has been
necessary to strip the reel .of all rolls, move the
35 two spiders individually and reload the reel.
With my construction, however, it is only neces
sary to press a button and the motor 28 will op
erate to move the roll-?lled reel from one side
of the machine to the other with practically no
40 loss of time and no effort.
In the construction shown, covers 18 and 19
on each of the three spindles and a center cover
80 are provided ‘on one spider, which is adapted
for a web splicing device. These covers can be
made removable or made integral parts of the
spider I6.
reel it is necessary to use selector rings for dis
tributing electric power ‘properly. This is done
by employing an insulation ring 31 secured to
the plate 25. This insulating ring has contact
rings 88, ?ve being shown but usually only two

against these-rings 88 with spring pressure pro
.duced by springs 40. A cap 4i is used to back
up the whole device'and this cap is mounted in
a sleeve 42 of bakelite or other insulating mold
able material. A wire‘ may be attached for sup
' plying electric power through the brushes 38 to
the contact rings 88 and thus to the motor 28
by means of a connection 48. This connection is
soldered to a sleeve 44 to provide the necessary
connection.
One spideris provided with movable chucks
58 to permit the mounting of the web rolls. This
is arranged'for by providing, in axial alignment
with each chuck, a shaft 48 inside a cylinder 48,
this shaft and cylinder telescoping together. A
cylinder 48 is mounted slidably in each arm of
70 the spider and held against rotation by a dowel

It will be understood that a simple reel could
be made not particularly adapted for use with
this automatic machine in a less elaborate man
ner.

Referring to Figs. 16 and 17 a limit switch con
struction is shown, which prevents the spider
from being jammed against the bearing box at
the end. This is shown in the form of a shoe 8i
guided in an upright position by a bracket 82
secured to the end bracket. This shoe is pinned
to a switch rod 88 which is spring-pressed and
has its bearing in the bracket 82 and also in the
end bracket. The switch rod 88 is provided with
a collar 84 against which the spring presses and 45

shaft of the limit switch 88.
It will be seen that the switch rod 83 is spring
pressed to the right in the position shown until
the cover plate 80' of the spider bears against the
upper part of the shoe ll which opens the switch
86 and disconnects the power automatically from
the motor 18. A similar switch construction is
used on the other end of the reel, as shown in
dotted lines in Fig. 2.
The motor 23 is reversible and of course, these
,switches operate to stop the motion of the spider
longitudinally of the shaft, only in one direction in
each case: that is, the direction in which they‘
move. This arrangement is provided, of course, 60
to prevent damage. It is possible to move the
spider or spiders in the opposite direction away
from the limit switch as is customary with limit
switches of this kind.

vcnient to unlatch one each for each page width
of narrowing of the paper when fractional width
rolls are used. When a half width roll is used,
two tension straps are used, for a. three-quarter
roll, three of them are used. They are very easily
thrown out of operation by unlatching the hook
89 and hanging the belt up over-a pipe 94 which
extends across the reel and is mounted on the

It will be seen that a rotatable paper roll-sup
porting device is provided which is sturdy in
construction, particularly on account of the
brackets 2, uses little or no floor room because it
is mounted on the columns of the press, within
the boundaries thereof, carries diseonnectible
means for moving the spider longitudinally on the
reel shaft by power and constructed to be used
in connection with very simple tension members
which can be put out of operation and brought
20 back into operative position very easily and
quickly.
Furthermore, it can be located high
enough in the machine so as to leave a clear ?oor
space underneath the reel for cleaning and re
any person skilled in the art without departing
from the scope of the invention as expressed in
the claims. Therefore I do not wish to be limited
in this respect otherwise than as set forth in
the claims, but what I claim is:--
