Abstract: A hydrostatic sewer cleaning machine for driving a cable and cleaning tool in from 6 inch to 30 inch diameter sewer lines. The sewer cleaning machine comprises a wheeled base having a baffled hydraulic fluid reservoir therebeneath and an inverted U-shaped operator's handle at its rearward end. A prime mover, a hydraulic pump and a hydraulic motor are mounted on the base. The primer mover drives the hydraulic pump which is connected to the reservoir. The hydraulic pump is connected to the hydraulic motor. The hydraulic pump has a control valve which controls the direction and the amount of flow of the hydraulic fluid to the hydraulic motor. The pump control valve is operated, via a cable, by a control lever mounted on the operator's handle. The pump also has a manual relief valve by which the static pressure in the system can be released. The hydraulic motor output is connected through a slip clutch to the cable which drives an appropriate remote cleaning tool.
Abstract: A coupler assembly having male and female coupler members, the female coupler member having at least one linear open ended slot therein adapted to receive a drive pin on the male coupler member, the female coupler member also having an annular opening angularly displaced with respect to the linear slot, the male coupler member also having a depressible locking pin adapted to be depressed by the female coupler member as the drive pin is inserted into the linear slot, the locking pin being positioned to enter the annular opening in the female coupler member when the projection reaches the inner end of the slot, thereby locking together the coupler members.
