ABSTRACT:
A tabulation rack having simple and inexpensive construction. The rack has a set of straight-sided pins (5 or 50) which act as stops. They are held by an elongated main beam (3 or 54) in opposed slots. In one embodiment a pair of coil springs (7) are deformed along their long axis within the area formed by the bridge (25) of beam (3) and the pins (5). In a second embodiment, a single music wire 52 is extended between staggered, round pins 50. Frictional drag holds the pins (5 or 50) in their set and clear positions.
