Abstract
A blade assembly for attachment to a shaft that is rotatable about an axis on a conduit cleaner. The blade assembly has a hub defining an axis to be coaxial with the rotational axis of a shaft to which the blade is mounted. A cutting blade is attached to the hub so that the cutting blade does not project through the hub axis.
Claims19
A blade assembly for attachment to a shaft that is rotatable about an axis on a conduit cleaner, said blade assembly comprising:
- a hub defining an axis to be coaxial with the rotational axis on a shaft to which the blade is mounted,
- said hub having a peripheral outer surface;
- first and second cutting blades;
- means for attaching the cutting blades to the hub so that the cutting blades do not project through the hub axis,
- whereby a fastener can be directed axially through the hub to engage a shaft to which the hub is mounted;
- and
- means connecting the first and second cutting blades to each other so that the first and second cutting blades reinforce each other.

A blade assembly for attachment to a shaft that is rotatable about an axis on a conduit cleaner, said blade assembly comprising:
- a hub defining an axis to be coaxial with the rotational axis on a shaft to which the blade is mounted,
- said hub having a forward wall with axially oppositely facing surfaces;
- first and second cutting blades;
- means for attaching the cutting blades to at least one of the hub and a shaft on a conduit cleaner to which the blade assembly attaches;
- means for connecting the forward hub wall to a shaft on a conduit cleaner;
- and
- means for connecting the first and second blades to each other at a location spaced radially from the hub so that the first and second cutting blades reinforce each other.
