Abstract
An implement for dislodging lumps of matter clogging a drainpipe comprises a long handle with a resilient cup attached to its lower end, the cup having several slits that extend from its rim down to form a plurality of petal-shaped leaves which yield inward when the cup is thrust from above into the pipe but which hug the pipe wall on being pulled up. On being vertically reciprocated inside the drainpipe, the cup thus acts as a pump drawing up water and dissolving the obstruction.
Claims5
An implement for dislodging a lump of matter obstructing a drainpipe, comprising an elongate handle and an upwardly open cup secured to the lower end of said handle, said cup being provided with slits extending from an upper rim down and dividing the periphery thereof into a plurality of petal-shaped leaves which are sufficiently flexible to yield inward when the cup is thrust down a water-filled pipe whose inner diameter substantially equals the outer diameter of the cup at said rim, said leaves tending to diverge upwardly while hugging the pipe wall under the weight of the water accumulated therein when the cup is being pulled up with creation of suction therebelow in said pipe.
