Abstract
A fluid applicator includes a fluid applicator roller engaged with a fluid dispersing roller. The fluid dispersing roller includes a pair of helical fluid dispersing troughs which receive fluid from a pump which is operated by a control located on a handle of the fluid applicator.
Claims12
A fluid applicator for applying fluid, such as paint or the like, to a surface, comprising:
- a source of fluid;
- a pump fluidly connected to said source of fluid;
- a frame having a fluid passage therein fluidly connected to said pump;
- a fluid applicator roller rotatably mounted on said frame;
- a fluid dispersing roller rotatably mounted on said frame to contact said fluid applicator roller, said fluid dispersing roller including a central fluid passage defined to extend axially of said fluid dispersing roller and to be in fluid communication with said frame fluid passage to receive fluid therefrom, a plurality of fluid transfer passages extending radially of said fluid dispersing roller and being in fluid communication with said central fluid passage, and a pair of helical fluid troughs defined in the outer surface of said fluid dispersing roller to be in fluid communication with said transfer passages to receive fluid therefrom, said helical troughs each intersecting each fluid transfer passage and each having a width dimension which decreases to a minimum adjacent a transfer passage, each of said helical fluid troughs including a ridge within each trough to establish capilliary action, said pump pressurizing fluid in said helical ridged troughs;
- and
- control means on said frame for controlling said pump.

- a source of paint;
- a pump fluidly connected to said source of paint;
- a frame having a fluid passage therein fluidly connected to said pump;
- a fluid applicator roller rotatably mounted on said frame;
- a fluid dispersing roller rotatably mounted on said frame to contact said fluid applicator roller, said fluid dispersing roller having an axially extending central fluid passage therein for fluid communication with said frame fluid passage to receive fluid therefrom, a plurality of radial fluid transfer passages in said fluid dispersing roller in fluid communication with said central fluid passage, a pair of helical fluid troughs defined in the outer surface of said fluid dispersing roller to be in fluid communication with said radial transfer passages to receive fluid therefrom, said helical troughs each intersecting each fluid transfer passage and each having a width dimension which decreases to a minimum adjacent a transfer passage, each of said helical fluid troughs including a ridge within said trough to establish capilliary action, said pump pressurizing fluid in said helical ridged troughs;
- said pump including a helical screw fluid conveyor which is fully immersed in the source of paint;
- said frame including a handle, control means on said handle for controlling said pump, an adjustment arm connected to a support rod for said fluid dispersing roller, and a head movably connected to said adjustment arm supporting said fluid applicator roller.
