The present invention vrelates to new and-'use
ful‘impr'ovements in ,apparatus‘used in coal min
ing; and" more particularly to a loadingv pan
adaptedfor loading the loose coal ’onto a shaker
conveyor'to remove the coal from the minework
mg.
An important ,objectV of' the present invention
is to provide meansA for loading the loose coal
onto-theishaker conveyor, whereby to eliminate
the- usualpractice of shovelingthe coal‘by hand
onto‘thec’onveyor.'
f

A1 further importantA object' ofthe present in
vention is to provide a’. flexible loading panv
adapted " for attaching tothe front end of a
conventional forïm of shaker conveyor and adapted
for moving one edge ofthe loading panjj under
the: Yloo’s‘e‘coal'for picking-Yup the,` coal and trans
ferring the same tothe conveyor;
