Strip Ribbon Reinking Cartridge

       To increase the volume of available ink in an impact
printer, the ink in the ribbon can be augmented with an additional
supply of ink from a saturated sponge.  A ribbon reinking system with
two symmetrical cassettes and details of the means to transfer ink
from the sponge to the ribbon are described below.

      Fig. 1 is an external view of the entire ribbon and reinking
assembly before it is installed in a printer.  Ink saturated ribbon 1
is wound on two spools 6 and 19 which are contained in cartridges 2
and 3, respectively.  Cartridge 2 is a mirror image of cartridge 3.

      Fig. 2 is a view of the interior of cartridge 2 with cover 4
removed to show the interior components in their operating positions
inside cartridge housing 5.  Ribbon 1 is wound on spool 6 which also
contains gear teeth 7 that mesh with gear teeth on the shaft of the
ribbon drive motor in the printer.  Hubs 8 on either end of spool 6
are journaled into bearings on cover 4 and housing 5.  Sponge roll 9
is saturated with ink and mounted on axle 10 which rotates freely in
bearings at the ends of arms on pivoting link 11. Spring 12 biases
sponge roll 9 against transfer roll 13. Guide roll 14 has flanges at
its ends and a central crown to guide ribbon 1.  The motion of ribbon
1 rotates transfer roll 13, and the friction between transfer roll 13
and sponge roll 9 causes rotation of sponge roll 9.  By this means,
ink which migrates to the surfac...
