摘要： A sewer rod turning machine safety device for machines which drive sewer cleaning rods. These machines are comprised of a motor driving a transmission which in turn drives a rod coupling drive shaft through a gear box. The motor transmission and gear box are all mounted on a wheeled cart. The rod turning machine has a shift lever attached to the transmission which will rotate the rods in forward or reverse direction. The shift lever has a center neutral position and the forward and reverse rotation positions are to either side of neutral. The safety device is comprised of a spring steel bendable rod engaging the shift lever which is designed to return the shift lever to center neutral position whenever it is released by an operator. A collar and bolt arrangement, securely fastening the safety bar to the gear box and the free end of the safety bar, has a loop wrapping around the shaft of the shift lever when securely mounted.

摘要： A device for testing sewer pipes comprised of an elongated section of conduit having a nozzle on one end and a coupling on the other end for coupling hose to feed the device into a sewer pipe and fluid to the nozzle. Intermediate the ends of the elongated section of conduit are a plurality of the deformable skids adapted to maintain the elongated section of conduit coaxial with the pipe being tested. The deformable skids allow the device to easily pass through the pipe being tested and to identify any blockages, irregularities or deformities. The tool can be used to test the true integrity of any pipe.

摘要： A mobile sewer cleaning machine comprises an elongated sewer cleaning tool wound upon a reel mounted in a reel compartment of the machine. A reel control motor is coupled to the reel to rotate the reel in one direction to play out the tool into a sewer by unwinding it, and in the opposite direction to retract the tool from the sewer by rewinding it. A rotatably mounted tool sensing drum is frictionally engaged with and rotated by the tool and includes a position indicator adjustably mounted to its side. Two proximity sensors are positioned to sense the position indicator as the drum is rotated by extension or retraction of the tool. To provide improved accuracy and ease of operation, the two proximity sensors are mounted opposite to one another across a diameter of the tool sensing drum. First and second switches are coupled to the reel control motor for activating one of the proximity sensors upon rotation of the motor in one direction and the other of the proximity sensors upon rotation of the motor means in the opposite direction. An electronic counter is connected to the sensors by the first and second switches for counting signals generated by the sensors and displaying a count representative of the extent of the tool which extends from the reel. The electronic counter includes input switches for entering a desired count and output contacts for indicating when an entered count has been reached. An audible and/or visual alarm is activated by the output contacts of the electronic counter upon reaching the desired count.

摘要： A method and apparatus provide for selective generation of pulses at water jets of a jet nozzle terminating a high pressure cleaning hose of a sewer cleaning machine. A ball valve is connected as a pressure bleeder to the high pressure side of the sewer cleaning machine pump and hence, the cleaning hose, for relieving pressure from the hose when the valve is open. A motor is connected to operate a rotatable element of the ball valve to automatically cycle the valve and generate a series of high pressure pulses at the water jets to thereby generate a hammering action to assist in penetration of blockages in a sewer being cleaned. The amplitude of the pulses is controlled by a second valve connected to the ball valve and the pulses preferably are generated at a frequency of approximately 3 hertz. The motor may be activated and deactivated by a blockage sensor which detects engagements of the nozzle with blockages formed by concentrations of refuse and debris within a sewer being cleaned.

摘要： An automatic sewer rodding machine having a carriage mounted storage reel rotatably driven by a hydraulic drive. A rod feed system also mounted on the carriage has a hydraulic drive to feed sewer cleaning rod out and back. An automatic rod feed reversing system senses resistance to rod movement and automatically reverses rod travel for a predetermined time period. After the period times out rod travel is restored to normal operation. The automatic reversing system continuously cycles the sewer cleaning rod into an obstruction in a sewer line until it is cleared. Switch selection of normal or reverse automatic rod feed or entirely manual operation is provided.

摘要： Protection apparatus in a mobile sewer cleaning machine having a compartment enclosing a reel and a hose wound thereon. The compartment has an opening through which the hose can be unwound into a sewer through a sewer opening, which leaves a portion of hose between the opening of the compartment and the sewer exposed. The reel and the hose are rotated by a motor to advance the hose through the sewer. The protection apparatus comprises a shield arrangement for enclosing the periphery of the exposed portion of the hose received through an opening therein and extending substantially the full length of the exposed portion of the hose toward the sewer opening. The shield arrangement is fastened to the cleaning machine so that the shield arrangement covers the opening in the compartment. The protection apparatus further comprises sensing means, mounted below the reel and the hose, for sensing the presence of a descending loop of hose from the reel and for providing a stop signal in response thereto, and actuating means, connected to the sensing means, for stopping the motor in response to the stop signal.

摘要： A hose feeder guide apparatus for paying out or reeling in hose from a hose reel mounted in a compartment on a mobile sewer cleaning machine. The hose feeder guide apparatus is comprised of a guide roller and a tension roller mounted in tandem with the hose passing between. The tandem rollers are mounted on a pivotal bar which is swung side to side by a handle to evenly pay out or reel in a hose. The tension roller is supported on the bar by a frame which encloses and retains the hose between the two rollers comprised of a hinge on one side and a clasp on the other for opening the frame to permit removal or insertion of the hose between the two rollers. As the hose is payed out, a counter coupled to the guide roller indicates the number of feet the hose has been extended. An additional feature is the provision of means for adding accessories to provide additional support for the hose.
