VThe box 6 of Fig. 1 is shown in more detail in
Figs-2 to 6 inclusive. This box is open-topped and
has a bottom Ill, a low end II, a high end I2, a
low side I3, and a high side I4. The high end I2
is provided with a wall I5 spaced apart therefrom
and slottedas at I-B to receive the free end of peel
This invention relates generally to the art of
handling solids, and particularly to new appara
tus for use with an open hearth charging ma-
chine in cleaning solids from the charging floor in
front of an open hearth furnace.
During the operation of an open hearth fur»
nace various solids are charged into the furnace
and some ofk those solids are spilled onto the
charging floor in frontl of the furnace. Hereto
fore such solids have been cleared away by hand

at the end of the peel. ' When the free end oi the
peel 5 is inserted between the-end wall I2 and
spaced wall I5 and the pins are inserted in holes

wise by the peel and' also moved sidewise when

shoveling which necessitated the expenditure of
considerable labor. The present invention pro

charging machine to clear away substantially all
such solids without the expenditure >of any sub
stantial amount of hand labor.
