The operation of the apparatus now will be de

shown in Figure 10, the upper counter is oper
ating in descending direction and the sun gear
255 on shaft [94 is rotating counterclockwise and
by its engagement with the planetary gears it
biases the frame 266 in a counterclockwise direc
tion with stop pin 269- on the planetary frame
against upper stop pin 268. In this position

sand at the commencement of the ?lling opera
tion, and when eighty gallons of water are dis
charged from the tank (due to introduction of
eighty gallons of fuel) the fuel counter will be
at eighty and the water counter will be at 19,920
and thus the pretripping notch 246 of the ascend
ing fuel counter would trip the pilot latch unless
means were provided to prevent this tripping ac
tion. The water counter now operates as a sub
tractive or negative counter while the fuel counter
operates as an additive or positive counter. This
pretripping action when the register is ascending
is not desired for certain purposes and I there
fore prefer to provide a cut out, shield or guard
to prevent this pretripping action except when
the register is descending, as will now be de
scribed.

operation of the counter. Lower weight 231 carries an extension 242 (Figs. 8 and 11) having a

rotated to the position shown in‘Figs. 9 to 12
