Abstract: A movable-head cloth-cutter bristle block cleaner for cleaning a conveyor-type bristle bed trained between the rotatable end units of a cloth cutter. The cleaner has a movable head attached to a cable cylinder which is coupled to the frame of the cloth cutter. The head moves substantially the entire width of the bristle bed. In one embodiment, nozzles are placed in several rows on the head and are positioned so that they extend into the bristles of the bristle bed. The movable head is coupled to a supply of compressed air. When the bristle bed moves, high volume, high pressure air is delivered to the head and then shoots out of the nozzles. The jetting action of the gas leaving the nozzles effects removal of debris contained within the bed. Because the cleaning head moves across the entire width of the bristle bed, fewer nozzles are needed to clean the bristle bed. This allows the air pressure coming out of the nozzles to be delivered at a high level.

Abstract: A three chambered hose cleaning and drying head which attaches to the back of a cleaning vehicle. The cleaning head allows hoses to pass through each of the three respective chambers. As a hose passes through the first of these chambers it is sprayed with an encircling high pressure stream of the cleaning fluid which effectively removes all dirt and debris from its surface. This chamber subsequently vacuums away the dirt debris and much of the excess cleaning fluid. The other two chambers are vacuum chambers which remove the fluid from the hose and transfer it back to the cleaning system in order to dry the clean hose. This system can easily be used each time the hose is loaded on the truck or any time as desired. Therefore, the hose stays clean and dry regardless of the condition in which the cleaner is being used.
