pile, enabling it to be withdrawn and fed to
the printing - machine (for instance) in the
usual manner.
Each of the finger-actuating mechanisms A'
5 and B' comprises a frame f, in which is jour-
naled a shaft f', equipped with cams /2 f3, an
arm fI, pivotally connected with said frame,
joined to and actuating the corresponding pa-
per-engaging finger and actuated by the cam
o f2, and an arm f5, actuated by the cam f3 and
serving to actuate a finger-lifting rodf6, joined
to the finger near its free extremity. A spring
f7, encircling the rod f, holds the finger de-
pressed during its working stroke. The shafts
15 f' are actuated in unison by any suitable
means. (Not shown.) Inasmuch as these
mechanisms form portions of well - known
mechanisms which are shown, for instance, in
the above-mentioned patent, further descrip-
20 tion here is unnecessary. It is sufficient to
say that the mechanisms are arranged and
timed to give to the fingers A and B working
strokes away from each other and to lift the
fingers from the paper and return them to
25 their initial positions at the proper time.
Inasmuch as it is a fact that in practice it
is necessary to give to the fingers a working
stroke which is greater than actually is re-
quired to straighten the top sheet of paper,
30 I provide means to prevent tearing of the
sheet, comprising a friction-roller g, prefer-
ably of rubber, journaled on a threaded stud
g', projecting laterally from the free end of
the paper-engaging finger, the roller being
35 confined on a bushing between collars g2. The
stud is equipped with a nut g3, which serves
to adjust the tension of a spring g, which
bears against the bushing. Thus it will be
seen that while the roller is free to rotate on
40 its journal still it is yieldingly held, so that
the roller will exert the necessary force to
straighten the sheet of paper and then roll
upon the paper until the working stroke of
the finger is completed.
45 Any suitable means may be employed for
actuating the fingers, and any suitable detail
of construction for enabling idle movement
of the rollers after the paper has been straight-
ened may be adopted.
5o What I regard as new, and desire to secure
by Letters Patent, is-
1. The combination with means of support-
ing a pile of paper and holding the paper ele-vated at two points, of two suitably-actuated
paper-engaging means having working strokes 55
away from each other and serving to straighten
the uppermost sheet and cause it to span the
space between the elevated points, for the pur-
pose set forth.
2. The combination with means of support- 6o
ing a pile of paper and holding the paper ele-
vated at two points, of two suitably-actuated
paper-engaging means having working strokes
away from each other and serving to straighten
the uppermost sheet and cause it to span the 65
space between the elevated points, and a noz-
zle having an orifice located between the ele-
vated points of the paper to direct a blast be-
neath the top sheet, for the purpose set forth.
3. The combination of paper - supporting 70
means, means for sustaining certain points in
the paper above the general level, thereby
producing a depressed plane bounded by in-
clines, a pair of fingers engaging the paper
near the inclines, and mechanisms serving to 75
move the fingers away from each other up the
inclines, thereby to straighten the uppermost
sheet, and serving then to lift the fingers and
return them to their initial positions, for the
purpose set forth. 8o
4. The combination with means for support-
ing sheets of paper with the body thereof on
a given level and certain points thereof ele-
vated, of a pair of fingers having working
strokes away from each other, and yieldingly- 85
held paper-engaging rollers supported on said
fingers, whereby the rollers will turn after
the paper has been straightened to enable the
working stroke to be completed without in-
jury to the paper, for the purpose set forth. 90
5. The combination with paper-supporting
means, of fingers provided with lateral jour-
nals, rollers journaled thereon, springs bear-
ing against said rollers, nuts confining said
springs, mechanisms serving to move said 95
fingers away from each other while maintain-
ing the rollers in contact with the paper and
then lift the fingers and return them to their
original position, and an air-injecting nozzle
located between said mechanisms, for the pur- 100
pose set forth.
