the entrance to guideway 38 to de?ne an opening of
approximately one card width to inhibit double card

Referring to the drawings;
FIG. 1 shows the stationary base 10 with a central cut
out portion 12 adapted to receive a vibrating table 11.
The advancing mechanism for the stack is mounted on
base 10 and includes a back-up plate vl4, with a laterally
extending arm 16. Arm 16 terminates in a block 18‘ which
is journalled on a guide rod 20 and is slidably movable
leftwardly and rightwardly thereon. Rod 20 is secured at
its ends in a frame 21 mounted on base 10* in a manner
better shown in FIG. 2.
A spring wound drum 22 is 50
also mounted on frame 21 and is coupled to block 181 to
exert a constant but yieldable force to advance back-up
forward ends of arms 68 and 70 of lever 66. Tamping
member 78 has a ?rst inclined portion 80 engageable with
the upper edges of the cards 24 and a second ?at portion
82' substantially parallel to the upper surface of table 11.,
It will thus be seen that the cards 24 in the leftwardly
advancing stack will be subjected to gradually increasing
forces downward until the stack is properly conditioned
into the proper state of even edge alignment.
