A further important object of this invention is to pro—
vide a paint roller coating apparatus which is of simpli- -
tied construction for economical manufacture and which
is operable with maximum facility to apply a uniform

coating of paint to a paint roller.
The foregoing and other objects and advantages of this
invention will appear from the following detailed descrip
tion, taken in connection with the accompanying drawing,
mounted upon the tray and stabilized against displacement
during manipulation of the hand crank.
‘The forward end of the frame members extends into the
tray and rests upon the bottom of the latter.
In this man
ner the applicator roll 34 dips into the paint contained in
the tray and the leveling roll 38 is elevated above the
level of paint, with the crank end of the shaft extending
outwardly over the upper edge of the side wall 20 of the
7 tray.
Means is provided for elevating the applicator roll 34
slightly above the bottom of the tray, to permit its unre
