In the provision of apparatus for automating account

need for apparatus capable of separating a succession of
bank checks. The checks involved are issued by nu

of substantial pressures on the sheets as they are separated.
This is particularly true when the sheets being separated
are of random sizes, thicknesses and types of paper and
high speed reliable separation is required. It has been
found that such apparatus may damage papers having
relatively soft interior bodies and hardened or glazed
surfaces, or papers having frayed or partially laminated
edges.
Accordingly, it is a further object of the invention to
provide apparatus capable of separating random sized
sheets of hard or strong and soft or weak papers at high
‘ rates of speed without damage to the papers.
A guide plate 34 is supported from the base plate 16
by bracket means, not shown in the drawing, and extends
vertically and perpendicular to the plate 16. The upper
end of the plate 34 is curved to the left as viewed in
‘FIGURE 1 and provides a guide or abutment above
which sheets from the stack 20 must pass as they are
fed to the left as viewed in FIGURE 1 by action of the
belt 22.
The sheet separating apparatus indicated generally at
12 in FIGURE 1, includes a pair of co-acting endless
belts 40 and ‘42. The belt 40 passes over pulleys 43 and
44. The pulley 43 is affixed to and driven by a shaft 45
passing through the plate 16 and driven as will be here
inafter described. The pulley 44- is an idler pulley

which has been contemplated, of applying that principle.

to the shaft 45, thus, when the clutch 78 is energized, the

pulley 53 ‘for the belt 42 is mounted on an arm 54 pivot

rotation therearound by means of a spring 55. Pulley 53
and an idler pulley 55 positioned approximately di
ametrically across the pulley 48 from the pulley 53,
serve to properly tension the belt 42 and to wrap the
belt 42 around a su?icient circumference of the pulley 48
to provide for effective driving of the belt 42 by the pul
ley 48. The belt ‘42 is driven in the opposite direction
from the direction of the drive of the belt 40, i.e., in the
direction indicated by the arrow 56.
A guide plate 60 is affixed to the base plate 16 by
means of brackets 61 and 62. The guide plate 60 extends
to the left of the belt 42, as viewed in FIGURE 1, as an
uninterrupted plate. However, the right hand end por
tion of plate 60 is cut and provides a leg extending on each
side of the belt 42 as shown at 64 and 65 in FIGURE 2.
A guide plate 66 is positioned above the plate 60 and to
the left of the belt 40 as viewed in FIGURE 1. The plate
66 is mounted by means of a bracket '67 affixed to the end
of the shaft 46 and has its right hand end portion 68, as
viewed in FIGURE 1, formed to extend beside and turned

tation of the hub 77. From the foregoing, it will be evi
dent that the belt 40 is advanced in the direction as indi
cated by the arrow 47 in FIGURE 1 at a relatively high
rate of speed whereas the belt 42 is rotated in the oppo
site direction, i.e., the direction indicated by the arrow 56
in FIGURE 1, at a relatively low rate of speed.
Accordingly, as sheets from the stack 20 are advanced
to the left as viewed in FIGURE 1 in overlapping relation
by the belt 22, the left hand end portions of the sheets
pass over the upper end of the guide plate 34, and over the
belt 42. As the sheets are moved further to the left, the
uppermost sheet ultimately engages the belt 40. It will be
recalled that belt 40' is traveling at a high rate of speed,
20 whereas the belt 42 is traveling at a relatively low rate of
speed and thus the action of the belt 40 predominates and
sheets are carried to the left thereby and delivered to the
space between the guide plates ‘60 and 66.

uppermost sheet is being advanced by the belt 40‘, any
sheets positioned thereunder are being moved baokwardly
by the rearwardly moving belt 42.
The reverse motion of the belt 42 is provided not only
to improve the separating action but also to present a
