are anchored to levers II and to collars I3 and
continuously tend to hold the iingers I8 with their
inserts I4 in the grooves 8. The inserts I4 (see
Figs. 4, 5 and 6) have ñat heads I5 which ride on

loop over the free edge of the plate l, and along
the plate between the guide bars 9, under the
feed fingers I8 by which ñngers the paper is ad
vanced to the body blanking mechanism. It will
be understood that when the paper is passed un

paper and thereby effect a positive connection
with the paper so that as the shaft I2 is advanced

What We claim is:
1. In a machine of the class described, a sup
port, a feed plate over which a continuous strip of
25
paper may pass, guide bars on said plate, and
a cam journalled on a stud carried by said sup
port, gear connections between said cam and said
drive roll shaft, a paper unwinder driven roll hav
ing a shaft mounted in said support in cooper
ative relation to said drive roll, a lever mounted
on said finger operating shaft and having a cam
roller to engage said cam, finger operating levers
secured to said finger operating shaft, feed fin
gers carried by said finger operating levers, paper
perforators on said fingers for engaging and per
forating the paper strip and feeding it forwardly,
means to disengage the perforators from the
paper at the end of the forward stroke of the 1in
gers and hold them free of the paper during the
back stroke of the fingers, means to- restore the
perforators to the paper at the end of said back
stroke, and means continuously tending to move
the fingers backwardly.
ger lifting means including a roller on one of said
fingers adapted to pass under said cam against
the action of said spring on the forward stroke
and to pass over said cam on the back stroke of
said fingers.
