Definitions

  • ABSTRACT A feed control apparatus for use in conjunction with a plumbing tool of the type used for cleaning and removing obstructions from drain pipes in which an elongated coiled spring wire, or plumbers snake, is advanced through the pipe and rotated.
  • the feed control apparatus includes a novel combination snake feed and chucking device which supports the rotating snake at all times and automatically controls the rate of feed of the snake through the pipe in accordance with the resistance encountered.
  • Field of the Invention This invention has to do generally with plumbers tools used for cleaning and removing obstructions from drain pipes and utilizing an elongated member in the form of a coiled spring wire, known as a plumbers snake, which is advanced through the pipe and rotated. More particularly, the invention relates to the provision of a novel, automatic feed device which will accommodate springs or snakes of various diameters, will accommodate distortions in the spring and will automatically vary the rate of axial feed of the spring relative to the impedance encountered by the spring as it advances through the pipe.
  • the feed mechanism typically includes a jaw in the form of a segmented nut, or the like, through which the spring is fed by rotating it so that, in effect, the spring is threaded through the jaw. Since the jaw is stationary, the rate of feed of the spring or snake is entirely dependent upon its speed of rotation.
  • the stationary jaw cannot accommodate irregularities in the spring such as kinks, couplings and the like and if such irregularities are encountered, serious damage to the equipment can result. Also, should the spring or snake encounter a restriction within the pipe which it cannot immediately penetrate, the driving torque will build up against the stationary jaw causing the snake to kink and frequently break, thereby creating a significant safety hazard.
  • the novel construction of the device of the present invention solves the aforementioned problems by providing a novel spring loaded combination snake feed and chucking device which can readily accommodate distortions or couplings in the snake and additionally automatically regulates the rate of feed of the snake from Zero to approximately 12 feet per minute depending upon the impedance encountered by the snake. For example, upon encountering a blockage in the pipe which results in a torque buildup in the snake and an impedance to further forward feed, the rate of feed will be automatically slowed to permit the snake to work its way past the obstruction. If the blockage is such that the snake cannot penetrate it, the impedance to forward movement of the snake is immediately sensed by the feed device and the rate of feed is instantly reduced to zero without any corrective action being required of the operator. In this way, the safety of the operator is assured and damage to the snake or to other parts of the equipment is prevented.
  • the feed mechanism includes snake engaging elements movable into and out of driving engagement with the snake and further includes a biasing mechanism for yieldably urging the snake engaging elements into driving engagement with the snake which is so constructed and arranged as to permit the elements to move out of driving engagement with the snake in response to forces opposing feeding of the snake axially of itself.
  • the mechanism is constructed so that when the feed rollers are in engagement with the snake, the entire assembly can function as a chucking device and rotate with the snake. Alternatively, the rotation of the mechanism can be stopped, thereby causing the feed rollers to rotate in an opposite direction relative to the rotation of the snake. Because the feed rollers rotate relative to the snake and because they are constructed with specially configured helical grooves about their periphery, the snake will be fed at a significantly advanced rate of speed as compared with a standard stationary jaw type device.
  • This unique construction permits the feed mechanism to automatically sense and effectively accommodate torque buildup and distortions of the snake.
  • a feed control apparatus for use with plumbing tools of the type having an elongated coiled spring wire or plumbers snake and a mechanism for rotating the snake about its longitudinal axis comprising a snake engaging subassembly movable into and out of driving engagement with the snake, an operating subassembly operably coupled with a snake engaging subassembly for moving the snake engaging subassem bly into driving engagement with the snake, and a biasing subassembly operably coupled with the operating subassembly for yieldably urging the operating subassembly into driving engagement with the snake.
  • the biasing subassembly is so constructed and arranged as to permit the snake engaging subassembly to move out of driving engagement with the snake in response to forces opposing feeding of the snake axially of itself.

  • the greater the loading on the spring the greater will be the resistance to rearward movement of interengaging means within housing 30. Stated another way, the greater the loading on spring 102, the greater will be the camming pressure exerted by cone member 78 against segments 40 and the greater will be the resultant gripping pressure exerted by rollers 46 against the coiled spring or snake 16.
  • the stop means or feed control means of the invention is generally designated by the numeral 116.
  • the purpose of the stop means is to permit the operator to stop the rotation of first means 36 and thereby cause the snake 16 to be fed forwardly or rearwardly of the housing depending upon the direction of rotation of the motor 18.
  • the stop means 116 comprises a lever arm 118 pivotally connected to housing 30 by means of a pivot pin 120.
  • a piston 122 is connected to lever arm 118 and is adapted to be moved within a bore 124 formed in housing 30 and cover plate 32 into and out of braking engagement with first means 36 upon corresponding upward and downward movement of lever arm 118.

  • first means 36 When the lever arm is in its normal upward position, as shown in FIG. 6, and the feed rollers 46 are in engagement with the rotating snake 16, first means 36, along with interengaging means 76, are free to rotate within housing 30.
  • the tool is now in the dwell or chucking mode.
  • piston 122 When the lever arm 118 is moved downwardly into the position shown in FIG. 7, piston 122 is moved into frictional engagement withthe support ring assembly of first means 36 causing the first means to stop rotating within housing 30. This will LII cause the feed rollers 46 to start to rotate in a direction l opposite the direction of rotation of the snake and, due
  • rollers 46 are mounted within segments 40at a slight angle ofan order of 7 relative to the longitudinal axis ofthe snake.
  • this novel configuration along with the unique i design of the helical grooves ,or channels formed around the periphery of the rollers, causes the snake 'to be fed at a rate several times faster than is possible with conventional tools embodying stationary feeding jaws.v
  • snake housing 14 along with snake l 16 can be caused to rotate in a clockwise direction
  • the snake will be fed forwardly of housing 30 at a rate of speed proportional to the speed of rotation of the snake.
  • the feed control apparatus can accommodate deformations in the snake such as kinks or couplings without endangering either the equipment or the operator. Referring to FIG. and assuming piston 122 is depressed so as to place the device in the feed mode, it can be seen that any kink, coupling or other deformation in the snake encountered by the feed rollers 46 will generate a force vector tending to move the rollers radially outwardly.
  • This force vector is transmitted to the sloping inner walls of conically shaped element 78 of interengaging means 76 where it will be translated into a force vector tending to move loading ring 82 axially rearwardly of housing 30 against the urging of the second biasing means or spring 102.
  • this force vector reaches sufficient magnitude to overcome the resistance of spring 102, the entire second. means 74 will be moved rearwardly of housing 30.
  • the control rod assembly 88 will move in a counterclockwise direction, as viewed in FIG. 4, and the snake engaging means will move toward the configuration shown in FIG. 3. This separation of the rollers 46 will, of course, pcrmit the deformation in the spring to pass.
  • the second biasing means or spring 102 will again urge the interengaging means forwardly of the housing, thereby camming the rollers 46 into gripping engagement with the coiled spring and causing the spring to be threaded forwardly relative to the rollers.
  • the ability of the snake engaging means to automati cally move into and out of engagement with the snake against the urging of the second biasing means in the manner just discussed also constitutes an important safety feature of the invention.
  • the equipment can be seriously damaged and the operator exposed to risk of significant injury.
  • the rate of feed of the snake in such eventualities is automatically controlled and the possibility of damage to the equipment or injury to the operator is effectively eliminated.
  • this force vector is translated into a radial force vector tending to move the rollers radially outwardly in opposition to the force exerted by spring 102.
  • This radial force vector causes the rollers to grip the snake with less force and, therefore, permits slippage between the rollers and the snake, which in turn, results in a decreased rate of feed of the snake proportional to the impedance encountered. If the blockage within the pipe is so severe that the snake cannot work its way past the obstruction and further forward, feed of the snake becomes impossible.
  • the resultant rearwardly directed force vector will simply cause the rollers to automatically move radially outwardly in a repetitive racheting-like manner with the helical grooves, in effect, jumping over the coils formed in the spring. In this way the forward feed of the snake is immediately and automatically reduced to zero. The operator can then reverse the motor so that the snake can be safely withdrawn from the pipe by the resultant reversed rotation of the rollers 46.
  • stop means itself. For example, if torque conditions become extreme, a slippage between the piston 122 and surfaces 54, 58 and 42 will result per mitting the assemblage to rotate within the housing thereby reducing the feed rate.
  • the operator can, of course, at any time release the feed lever 118 at any visual sign of extreme torque conditions, thus instantly returning the feed rate to zero and returning the grooved rollers to a grip action on the coiled spring.
  • the loading on spring 102 can be increased by means of the loading adjusting mechanism in the manner previously described. Increased loading on the spring will, of course, cause the rollers 46 to be urged against the snake with greater force and the opposing vertical force vector generated by impedance to forward movement of the snake must be of greater magnitude to affect radially outward movement of the rollers and concomitant slippage between the rollers and the snake.
