Pump Assembly Carrying Rasp

A dispenser for dispensing of a fluid and particles of a solid material comprising:

• a reservoir containing the fluid,
• a pump which in a cycle of operation draws the fluid from the reservoir into the chamber and dispenses the fluid out an outlet,
• a block of the solid material coalesced together,
• a rasp, which during the cycle of operation of the pump, moves relative the block in engagement with the block whereby the rasp erodes the block by disengaging the particles from the block,
• a particle discharge chute receiving the particles disengaged from the block and directing the particles under gravity downwardly to a particle exitway adjacent the outlet.

A dispenser for simultaneous dispensing of a fluid and particles of a solid material comprising:

• a reservoir containing the fluid,
• a piston pump having a piston chamber-forming body forming a chamber therein and a piston-forming element reciprocally coaxially slidable in the chamber for movement between a retracted position and an extended position relative the piston chamber-forming body,
• the piston element and the piston chamber-forming element are coaxially reciprocally slidable about an axis,
• wherein in a cycle of operation the pump draws the fluid from the reservoir into the chamber and dispenses the fluid out an outlet carried on the piston-forming element extending out an open end of the chamber,
• a block of the solid material coalesced together,
• the block carried by the piston chamber-forming body,
• a rasp carried by the piston forming member,
• the rasp and the piston-forming element mechanically linked whereby coaxial sliding movement of the piston-forming element relative the piston chamber-forming body moves of the rasp relative the block whereby the rasp erodes the block by disengaging the particles from the block,
• a particle discharge chute receiving the particles disengaged from the block and directing the particles under gravity downwardly to a particle exitway adjacent the outlet.
