20090292502 | DRAIN CLEANING APPARATUS WITH ELECTRONIC CABLE MONITORING SYSTEM - A drain cleaning machine with an electronic cable monitoring system is disclosed which comprises a frame supporting a rotatable drum which is driven by a motor through an endless belt. The drum contains a flexible drain cleaning cable which is rotatable with the drum and axially displaceable into and out from the drum, and the frame supports a cable feeding device through which the cable extends and by which the cable is displaced into and out of the drum. An electronic cable monitoring system is configured to assess an amount of cable payed out from and retracted into the drum. A process determines an amount and direction of relative movement between a rotatable drum and a cable follower member and generates a signal representative of an amount of cable payed out or retracted into the drum. | 11-26-2009 |
20100031460 | DRAIN CLEANING APPARATUS WITH ELECTRONIC CABLE COUNTER - A drain cleaning machine with an electronic cable counter is disclosed which is of the character comprising a frame supporting a rotatable drum which is driven by a motor through an endless belt. The drum contains a flexible drain cleaning snake which is rotatable with the drum and axially displaceable into an out from the drum, and the frame supports a cable feeding device through which the cable extends and by which the cable is displaced into and out of the drum. An electronic cable counter is configured to count an amount of cable payed out from and retracted into the drum and includes first and second sensor portions mounted on the rotatable drum and a cable follower member, respectively to sense relative rotational movement therebetween. A process determines an amount and direction of relative movement therebetween and generates a signal representative of an amount of cable payed or retracted into the drum. A fixed receiver unit is mounted to the frame and includes a human readable display portion and a receiver portion configured to receive the signal generated from the processor portion. | 02-11-2010 |
20100050350 | VARIABLE BELT TENSIONER FOR DRAIN CLEANING DEVICES - An assembly for adjusting belt tension in a drain cleaning device is disclosed. The assembly includes an idler pulley assembly in which a pivotable idler pulley is urged against a belt by a tensioned spring. The tensile force exerted by the spring can be adjusted or otherwise changed by a rotatable spool engaged to the other end of the spring. | 03-04-2010 |
20120203501 | DRAIN CLEANING APPARATUS WITH ELECTRONIC CABLE MONITORING SYSTEM - A drain cleaning machine with an electronic cable monitoring system is disclosed which comprises a frame supporting a rotatable drum which is driven by a motor through an endless belt. The drum contains a flexible drain cleaning cable which is rotatable with the drum and axially displaceable into and out from the drum, and the frame supports a cable feeding device through which the cable extends and by which the cable is displaced into and out of the drum. An electronic cable monitoring system is configured to assess an amount of cable payed out from and retracted into the drum. A process determines an amount and direction of relative movement between a rotatable drum and a cable follower member and generates a signal representative of an amount of cable payed out or retracted into the drum. | 08-09-2012 |
20130160227 | FEED CONTROL LOCK FOR HAND OPERATED DRAIN CLEANER - A hand operated drain cleaner includes a manually operated rotatable drum and an elongated flexible cable at least partially held in the drum. A portion of the cable extending from the drum has a cable axis, and rotation of the drum rotates the cable portion about the cable axis. A handle is adapted to rotatably support the drum. The handle includes a barrel portion and a handle portion. A feed control device includes a housing having a feed passage axially therethrough for receiving the cable and a trigger for moving the feed control device between a non-actuating position and an actuating position. In the actuating position, a feed control device is pivoted relative to the handle such that the driving mechanism engages the cable thereby inducing axial movement of the cable via rotation of the drum. A locking mechanism is opera operably associated with the feed control device. | 06-27-2013 |
20140192180 | INSPECTION SYSTEM AND METHOD FOR USE IN UNDERGROUND BORING OPERATIONS - An inspection system and method for use in underground utility construction, especially underground boring operations, is provided. The inspection system generally includes a sensor, a sensor carrier apparatus, and an output device. The sensor is employed to obtain inspection data regarding the condition of a tunnel created in an underground boring operation. The sensor carrier is adapted to incorporate the sensor and connect to means for transporting the sensor through the tunnel. The output device receives an output signal from the sensor corresponding to the inspection data and presents it to an operator for interpretation and/or otherwise documents and/or records the inspection data. | 07-10-2014 |
20150040731 | TRANSPORTABLE BEVELING TOOL - Beveling tools having a variety of features are described. The tools can utilize a combination of handles, a protective external frame, guide rollers that are positionally adjusted by swing arms with timing lobes, or by an alternative guide bar mounting system, a helical knurled drive roller, guide rollers that have a convex or crowned face, skewed guide rollers, a positive clutch assembly for governing force applied to the guide rollers, a hand crank assembly for moving the tool when mounted on a workpiece, position adjustment provisions for varying the position of a milling head, and indicators providing visual feedback to an operator. | 02-12-2015 |
20150105163 | CABLE COUPLING - Cable coupling assemblies are described which can be readily engaged and separated from one another. The couplings are particularly useful for use in torque transmitting cables such as those used in drain cleaning applications. | 04-16-2015 |
