Definitions

  • This invention relates to the art of drain cleaning apparatus and, more particularly, to an improved feed control arrangement by which a flexible snake of such apparatus can be axially advanced and retracted relative thereto during a drain cleaning operation.
  • a plurality of rolls are supported in a housing, or the like, through which the snake extends, and the rolls are spaced apart about the periphery of the snake.
  • the rolls have neutral and engaged positions relative to the snake and in which the snake, when rotated, respectively rotates in place and is axially displaced relative to the housing.
  • the rolls are skewed relative to the axis of the snake so as to axially displace the snake in one direction relative to the housing in response to rotation of the snake in one direction, and axial displacement of the snake in the opposite direction is achieved by reversing the direction of rotation of the snake.
  • the power source by which a drain cleaning snake is rotated can be a handheld, crank operated drain cleaner such as shown for example in the aforementioned patent 6,158,076 to Rutkowski, et al. a trigger actuated motor driven drain cleaner such as are shown, for example, in patents 3,224,024 to Hunt and 5,029,356 to Silverman, et al., or somewhat larger, ground-supported drain cleaners such as are shown for example in patents 4,580,306 to Irwin, 5,031,263 to Babb, et al., and 5,239,724 to Salecker, et al., the disclosures of which are also incorporated herein by reference for background information.
  • control devices which do not require reversal of the direction of rotation of the snake in order to achieve displacement thereof in axially opposite directions are advantageous for a number of reasons.
  • operation of the drain cleaning apparatus is made easier for the user by the latter's not having to manipulate a reversing switch for the drive motor.
  • the arrangements heretofore provided for axially displacing a snake in opposite directions without changing the direction of rotation of the snake are structurally complex and at least somewhat cumbersome to operate in requiring the user to manipulate at least one and sometimes two components to achieve reversal of the direction of the snake drive.
  • a snake feed control device is provided in accordance with the present invention which retains the advantages of devices heretofore available and operable to obtain reversal of the axial displacement of a snake relative to the feed device without changing the direction of rotation of the snake about its axis while minimizing or overcoming the disadvantages of such devices and providing improvements in the maneuverability and ease of operation thereof.
  • a feed control device in accordance with the present invention is elongate in the direction of axial displacement of the snake, providing a user friendly size and profile for the device, and comprises, basically, base and actuator members which cooperate, selectively, to provide for axial displacement of a snake in opposite directions without changing the direction of rotation of the snake.
  • one of the members is displaceable relative to the other by a simple axially directed sliding movement of the user's hand, such movement in one direction providing for advancing the snake into a drain and, in the other direction, providing for retraction of the snake from the drain.
  • the snake driving components are two groups of rollers axially spaced apart relative to a snake to be displaced, each group comprising a pair of rollers on one of the members and at least one roller on the other member.
  • Another object is the provision of a feed control device of the foregoing character in which displacement of the snake in axially opposite directions relative thereto is achieved by an axial displacement of the user's hand in opposite directions relative to the device.
  • a further object is the provision of a feed control device of the foregoing character comprising a minimum number of component parts which are structurally interrelated to promote ease of operation, economy with respect to manufacture, and efficiency with regard to directional displacement of a flexible snake relative to a drain to be cleaned.
  • Yet another object is the provision of a feed device of the foregoing character which is operable in response to axial displacement of a user's hand in opposite directions relative to a direction of displacement of a snake relative to the device.
  • Still another object is the provision of a device of the foregoing character comprising axially spaced apart groups of drive rolls on relatively displaceable members of the device such that axial displacement of a user's hand in opposite directions relative to the device alternately displaces the groups of roll into driving engagement with a snake therebetween to, alternately, axially displace the snake in opposite directions relative to the device.

  • Figures 1-5 illustrate a snake feeding device 10 which, in accordance with the invention, is operable to selectively drive a drain cleaning snake, not shown, in opposite directions relative to axis A of the device.
  • the device comprises, basically, two component parts, namely a trough-shaped base 12 having axially opposite ends 12a and 12b and an actuator 14 which axially overlies the base and is pivotally interconnected therewith by means of a pin 16 which provides a pivot axis B transverse to axis A and generally centrally between the opposite ends of the base.
  • the base and actuator components can be of metal or a suitable plastic such as, for example, a fiber filled polypropylene.
  • Actuator 14 includes legs 18 and 20 extending in axially opposite directions relative to axis B and at an angle to one another which, as will become apparent hereinafter, provides for the legs to be alternately displaced toward base 12.
  • the snake feeding device further includes first and second sets of drive rolls 22 and 24, respectively, which sets are axially spaced apart and on axially opposite sides of pivot pin 16.
  • roll set 22 includes a single roll 22a mounted on a wall 23 in base 12 and a pair of rolls 22b and 22c mounted on leg 18 of actuator 14, and roll set 24 includes a single roll 24a mounted on a wall 25 in base 12 and a pair of rolls 24b and 24c mounted on leg 20 of the actuator.
  • Rolls 22a, 22b and 22c are canted relative to axis A so as to drive a snake in one direction relative to the device when the rolls of set 22 engage about the snake and the latter is rotated, and rolls 24a, 24b and 24c are canted in the opposite direction relative to axis A so that a snake engaged between the rolls of roll set 24 is driven in the opposite direction relative to the device in response to rotation of the snake in the same direction.
  • the actuator is in the position shown in Figures 1 and 2
  • the rolls of sets 22 and 24 are spaced apart such that a snake extending through the device is not axially displaced relative thereto in response to rotation of the snake. This is a neutral position of the actuator.
  • actuator 14 includes a central mounting portion 26 extending downwardly therefrom and having axially opposite ends, not designated numerically, upon which rolls 22b and 22c of roll set 22 and rolls 24b and 24c of roll set 24 are mounted.
  • Mounting portion 26 includes a pair of downwardly extending trunnions 28 between the axially opposite ends thereof and which are spaced apart relative to axis B to receive a rib 30 on base 12 therebetween.
  • Trunnions 28 are provided with pin openings 32 aligned with a pin opening 34 in rib 30 and a pin opening 36 in one of the laterally opposite sides of base 12.
  • Pivot pin 16 extends through an elongate opening 37 in the other of the sides and through openings 32, 34 and 36 to removably mount actuator 14 on base 12.
  • One of the outer ends of pin 16 is provided with barbs 38 which frictionally engage in opening 32 in the adjacent trunnion 28 to removably hold the pin in place. Removability of the pin is desired in connection with separating actuator 14 from base 12 to facilitate introducing a bulb auger on the end of a snake through the feeding device.
  • the outer ends of actuator legs 18 and 20 are provided with openings 18a and 20a therethrough which provide tool access to the corresponding one of the rolls 22b and 24b on the actuator.
  • the feeding device can be used in a number of different ways.
  • one or the other of the ends 12a and 12b of base 12 of the device can be attached to a flexible guide tube 40 as shown, for example, in patent 6,009,588 to Rutkowski mentioned herein.
  • the device can be mounted on the outer end of a handheld manually operated drain cleaner.
  • the device can be mounted on or adjacent the frame or drum of a large motor driven drain cleaning machine as well as on the outer end of a handheld motor powered drain cleaner.
  • the device can be held in a user's hand independent of attachment directly or indirectly to a drain cleaning machine so as to achieve axial displacement of the snake relative to the device in response to rotation of the snake relative thereto.
  • a guide tube 40 With regard to mounting a guide tube 40 to the device ends 12a and 12b of base 12 are circular and have bridging portions 42 and 44, respectively spaced axially inwardly of the corresponding one of arcuate terminal ends 43 and 45 of the base, and the inner surfaces of the latter ends and the bridging portions, which are dramatically opposite each other, are provided with corresponding circumferentially extending ribs 46 and 48, respectively. Ribs 46 and 48 frictionally interengage with the outer surface of the guide tube which is thereby axially interengaged with the device by the pairs of ribs which cooperatively engage about the periphery of the guide tube.
  • Other mounting arrangements can readily be devised to accommodate attachment of the feeding device to another device or apparatus.
  • FIGS 6-8 illustrate a modification of the mounting arrangement of the actuator from that shown in Figures 1-5.
  • the other component parts of the device are the same as those in the embodiment of Figures 1-5 and, accordingly, are designated by like numerals.
  • pivot pin 16 is replaced by posts 50 extending laterally outwardly from flexible tabs 52 on the laterally opposite sides of actuator 14A and which posts are pivotally received in openings 54 in trunnions 56 on laterally opposite sides of base 12A.
  • side walls 26a of mounting portion 26 of actuator 14A are each provided with a pair of axially spaced apart vertical slots 58 which define the corresponding tab 52 and which, because of these slots, is adapted to be displaceable laterally inwardly of the corresponding trunnion 56 to disengage actuator 14A from base 12 A. Accordingly, it will be appreciated that a user can squeeze tabs 52 laterally inwardly relative to one another in order to remove the actuator which, as in the embodiments of 1 -5, facilitates feeding a bulb auger on the end of a snake through the device.
  • the lower ends of posts 50 are provided with camming surface 50a which engage the upper ends of trunnions 56 to displace the tabs inwardly during remounting of the actuator to facilitate the remounting.
  • openings 54 are offset toward one of the axially opposite sides of the corresponding trunnion and the area of juncture between legs 18 and 20 of the actuator is provided with radially inwardly extending slots 60 profiled to preclude mounting of actuator 14A on base 12A other than in the orientation shown in Figure 6. This, of course, assures that the rolls in each of the roll sets are canted in the same direction.
  • edges 6OA of recesses 60 would engage vertical edge 56A of trunnions 56 to preclude the necessary alignment between posts 50 and openings 54 in the trunnions.
  • a modification of base 12A in this embodiment resides in the provision of ribs 62 and 64 in end 12a of the base to preclude attachment of a guide hose to that end of the device. More particularly in this respect, as will be appreciated from Figures 6 and 7, in comparison with Figure 2, ribs 62 and 64 in end 12a of the base have a radial extent generally corresponding to the wall thickness of a guide tube, whereby insertion of the latter into end 12a of base 12 A would be precluded by abutting engagement between the end of the tube and the ribs 62 and 64.
  • the resiliency of the guide tube material enables movement of a guide tube laterally past and thus into frictional engagement with ribs 48 on bridging portion 44 at end 12b (not visible) and ribs 46 on arcuate end portion 45 at end 12b.
  • FIG. 9-13 illustrate yet another embodiment of a snake feeding device in accordance with the present invention.
  • the feeding device 70 comprises a trough-shaped base member 72 and an actuator defined by first and second actuator members 74 and 76, respectively, pivotally mounted on base 72 as set forth more fully hereinafter and extending axially in overlying relationship to the base.
  • Feeding device 70 further includes first and second sets of drive rolls 78 and 80, respectively, defined by single drive rolls 78a and 80a mounted on base 72, and pairs of drive rolls 78b and 78c and 80b and 80c respectively mounted on actuators 74 and 76.
  • Base 72 is structurally similar in some respects to bases 12 and 12 A of the embodiments described hereinabove and, accordingly, component parts of the device illustrated in Figures 9-13 which correspond with those of the earlier embodiments are identified by like numerals.
  • Base 72 has an axis A, axially opposite ends 72a and 72b and upstanding mounting plates 82 on laterally opposite sides of the base and generally centrally between ends 72a and 72b thereof.
  • Rolls 78a and 80a are mounted on base 72 on axially opposite sides of mounting plates 82.
  • End 72a of the base has ribs 62 and 64 on arcuate end portion 43 and bridging portion 42, for blocking the mounting of a guide tube to that end of the base as described herein, and end 72b of the base has ribs 46 and 48 on arcuate end portion 45 and bridging portion 44 for engaging a guide tube with the latter end as described herein.
  • Actuators 74 and 76 have axially inner ends 74a and 76a, respectively, which as described hereinafter have an interengaging tongue and groove profile providing for the inner ends to overlap, and the overlapping portions and mounting plates 82 are provided with laterally aligned openings, not designated numerically, for receiving a pin 84 by which the actuators are pivotally engaged with base 72.
  • Actuator 74 is provided on the underside thereof with a pair of drive rolls 78b and 78c in overlying relationship with roll 78a of roll set 78, and the underside of actuator 76 is provided with a pair of drive rolls 80b and 80c which overlie drive roll 80a of roll set A which is mounted on base 72.
  • base 72 is arcuate in cross-section adjacent the central portion thereof and is provided with a pair of spaced apart walls 83 having axially inner sides on which the corresponding one of the drive rolls 78a and 80a is mounted.
  • the axially innermost portion of end 74a of actuator 74 provides the tongue component of the tongue and groove profile between the inner ends of the actuators.
  • the tongue component is defined by a pair of fingers 74b which are laterally spaced apart to receive a biasing spring 86 therebetween, which spring surrounds pin 84 and has opposite ends 86a and 86b extending axially outwardly into engagement with actuators 74 and 76, respectively, so as to bias each of the actuators downwardly toward base 72.
  • the axially overlapping inner ends of actuators 74 and 76 have interengaging finger and shoulder elements 88 and 90, respectively, which interengage to limit pivotal movement of the actuators toward base 72.
  • the finger and shoulder elements interengage so as to provide a space between the upper and lower rolls of the corresponding roll set which is sufficient for a snake to pass therebetween and rotate relative to the roll sets without being axially driven thereby.
  • such positional relationship between the rolls of the roll sets provides a neutral position with respect to driving or feeding the snake relative to the device.
  • actuators 74 and 76 are adapted to be pivoted upwardly relative to base 72 to displace driving rolls 78b and 78c and 80b and 80c radially outwardly from the underlying rolls of the corresponding roll set. This position advantageously enables a snake having an enlarged auger end to be passed through the device along the axis thereof without having to disassemble any parts of the device.
  • a snake extends through the device, and a user can selectively depress either one of the levers 74 and 76 toward base 72 to engage the snake between the drive rolls of the corresponding roll set, whereby the snake will be axially displaced relative to the device upon rotation of the snake relative thereto and in the axial direction depending on which of the roll sets is engaged therewith.
