' This invention relates to apparatus for cleaning out conduits, and more particularly to an anger device for cleaning out the conduits associated with a toilet stool.

, A main object of the invention is to provide a novel and improved conduit cleaning device which is simple in construction, which is easy to operate, and which is adapted to guide the head of a flexible stool auger over the top of the trap in a conventional toilet stool.

A further object of the invention is to provide an improved conduit cleaning device for use in cleaning out traps and similar conduits having reverse bends, for example, the trap in a conventional toilet stool, the device being inexpensive to fabricate, being durable in construction, and being provided with means for properly guiding and directing the auger head of the device so as to reverse the direction thereof over the top of the trap in a toilet stool or similar location.

Further objects and advantages of the invention will become apparent from the following description and claims, .and from the accompanying drawings, wherein:

Figure 8 is an enlarged fragmentary longitudinal crosssectional view taken through a lower portion of the device of Figure 7.

Referring to the drawings, 11 generally designates an improved conduit cleaning device according to this invention. The device 11 comprises a rigid main conduit 12 having a straight main portion 13 and an arcuately' curved end portion 14. Designated at 15 is a resilient tubular auger guide which is slidably engaged through the main conduit 12 and which is provided at the end thereof adjacent the straight portion 13 with a handle 16 rigidly secured thereon, the handle 16 and rotatable 17 formed at its outer end with a crank portion 18 and provided with a further handle 19 which is employed to Extending axially through rotate the shank 17, the handle 19 being rotatable on 18, said end porthe end portion of the crank member tion being shown at 20.

;As shown in Figure 1, the shaft member 17 extends through the flexible auger guide 15 for a substantial distherein is a shaft member 65 loops 31 formed on the flexible tance and is secured at its reduced inner end 21 in the end of a resilient auger member '22 which extends rm tatably through the flexible tubular auger guide 15 and which projects therefrom at the end thereof opposite the handle 16, being formed at said opposite end with the helically coiled hook-like portion 23.

As will be readily apparent, the flexible auger guide 15 is slidable through the rigid main conduit 12, whereby said auger guide and the projecting portion 23 of the resilient auger member may be advanced through a conduit being cleaned while the operator holds the handle 16 with one hand and rotates the crank 18 with the other hand, thus rotating the hook-like portion 23 in the conduit.

In the conduit cleaning devices of the prior art, it is usually not possible to reverse the direction of the free end portion of the flexible auger guide when passing over the top of the trap 24 of a conventional toilet stool 25. Inv accordance with the present invention, means are provided for reversing the direction of the auger guide at this point. Thus, a lever 26 is pivoted at 27 on a lug 28 formed on the lower portion of handle 16, namely the end portion of the handle adjacent the end of the rigid conduit member 12. A flexible cable mem-' ber '29 is connected at one end to an eye loop 30 provided on the handle 26. The cable 29 extends through spaced auger guide 15, for ex ample, by enlarging the turns of said auger guide at spaced points therealong to define such loops.

Figures 3, 4 and 5 illustrate the manner in which the enlarged spaced turns of the resilient tubular auger guide 15 are formed to define the guide loops 31 which slidduit 12. Said rigid main conduit is formed on its outer side with an auxiliary guidechannel 33 in 'which'the' loops 3-1 and the cable 29 are receivable, said loops being, slidable in said auxiliary guide channel 33.

The end of the cable 29 is secured to the endportio'n of the tubular guide 15 at the final guide loop thereof; shown at 31. w l

As will be clearly apparent from Figure 1, the lever 26 may be rotated in a counterclockwisedirection, ex-' erting tension on the flexible cable 29, which is' trans-, mitted through the endretaining loop 31, whereby to, exerta bending force on 'the end portion of the resilient tubular auger guide 15. Thus, as shown in Figure 2,' the device may be inserted in the toilet bowl"2 5 with" the arcuate portion '14 of the rigid-main conduit12en gaged in the outlet passage of the toilet bowl and di-j' rected toward the trap 24. The auger guide 15 0011-. taining the resilient auger member 22 may then be forced through the trap 24 until the end portion 23 of the re-fl silient auger member 22 extends well over the top (if.

the trap, namely extends over the intervening wall por-' tion 34, shown in Figure 2. Theendportion of the auger guide 15 likewise must extend over the top of the, wall portion 34. At this point, the lever 26 may berfo-fl tated from the position thereof shown in Figure 1 the position thereof shown in Figure 2, namely to a po tion wherein the lever is adjacent to the handle 16, where-i by the tension developed in the cable 29 causes thevfr end portion of the tubular auger guide 15 to be bent arcu f ately over the top of the trap wall element 34, as shown f in Figure 2. The resilient auger member 22 may then be pushed through the trap, being guided by thereverse' bend defined at the free end portion of the tubular augerf guide 15, as shown in Figure 2, and may be thus moved past the trap 24 into the remaining portion of the conduit to be cleaned,

As will be readily understood, the shank member 17 is of substantial length and is slidable as well as rotatable in the handle 17, whereby the resilient auger member 22 may be advanced as well as rotated relative to the resilient tubular auger guide 15.

A suitable arcuate tubular protective casing 35 is provided on the arcuate portion 1401? the rigid main conduit 12, the protective casing 35 having a smooth outer surface so as to prevent damage to the surfaces of the toilet bowl engaged therewith during the use of the conduit cleaning device. The resilient tubular auger guide 15 and the flexible auger member 22 are formed in the conventional manner of helically coiled wire, or the like.

Thus, the resilient tubular auger guide 15 normally tends to return to a straight condition, whereby the cable 29 biase's the lever 26 to the outwardly projecting position thereof shown in Figure 1.

Referring now to Figures 6, 7 and 8, a modified form of conduit cleaning device is designated generally at 11. The device 11' comprises the rigid main conduit 12' having a straight main portion 13 and an arcuately curved end portion 14. Designated at 15 is a resilient tubular guide member which is rigidly secured at one end on the end of the arcuate conduit member 14'.

A resilient auger member 22' extends rotatably and slidably through the rigid conduit 12' and projects from the resilient guide member 15', terminating in the helical hook element 23'. A shaft 17 provided with a handle 18 extends into the straight rigid conduit portion 13' and is secured to the end of the auger member 22.

An arcuate outer guard sleeve 35 is secured in the arcuate portion 14' and is formed at its outer side with the guide channel 33. A flexible cable guide conduit 40' is secured to the outer side of rigid conduit 12 and to the resilient guide member 15, extending through the channel 33' and terminating a substantial distance short of the free end of guide member 15. A flexible cable 29 extends slidably through the guide sleeve 40'. The upper end of cable 29 is secured to a lever 26' pivoted to a lug 28 projecting outwardly from the upper end portion of rigid conduit 12' adjacent the top end of guide sleeve 40. The lower end of cable 29 is secured to the free end of guide member 15' at 42', as shown in Figure 6, whereby clockwise rotation of lever 26', as viewed in Figure 6, causes guide member 15' to be bent arcuately downwardly from its normal straight configuration, causing the hooked end of auger member 22 to be directed downwardly. I

As in the previously described form of the invention, the hooked end portion of the auger member 23' may be rotated by rotating handle 18' and may be advanced by pushing shaft member 17 downwardly into the straight portion of the rigid conduit member 12.
