Thickness Compensating Envelope Drive

      Disclosed is a cooperating roller system useful for
moving flat objects in a desired direction.  The roller system is
especially useful in deposit slots of automatic banking machines
which must accept envelopes of variable thickness.

      The roller drive system is shown schematically in Fig. 1.
Rollers 10 are attached to shaft 12 which is rotated in direction 14
by an external source.  Shaft 12 extends through round openings in
blocks 16 and 18 and is secured to the miter gear 20.  Rollers 22 are
attached to the shaft 24 which is attached to the miter gear 26.
Shaft 24 is free to move in directions 28 because of the slotted
configuration of the openings in the blocks 16 and 18 for guiding
shaft 24.  Thus, the spacing between the rollers 10 and 22 can be
changed to accommodate the thickness of the envelope 30 which would
move into the plane of the figure when shaft 12 is rotated in
direction 14.

      The coupling between the two shafts is provided by the shaft 32
and the miter gears 34 and 36.  Gear 34 is pinned to shaft 32,
whereas gear 36 is secured to shaft 32 by a key, slot, or
non-circular shaft which allows movement of the gear in direction 28
along the shaft while still retaining rotational coupling.
Therefore, as the shaft 24 is moved apart from shaft 12 to compensate
for a thicker envelope, gear 36 slides along shaft 32 and remains
engaged with gear 26.  The rotational force applied to gear 34 from
s...
