  • Patent number: 4163457
    Abstract: A hose receiving member constructed as a unitary plastic article is specifically adapted to connect an anti-kink corrugated plastic hose to an appliance such as an automatic washer in either a standpipe installation or a laundry tub installation when used with a metal or plastic hose guide member. The plastic hose guide member connects to an outlet pipe of the member near an upper end thereof adjacent an end of the corrugated hose. This guide member has a curvilinear upper surface which curves from a vertical orientation adjacent the end of the hose connection fitting through an arc of at least 180.degree. in a plane including an axis of the outlet pipe. A planar rib maintains the surface in its desired shape. Two retaining ties on the guide member grasp the hose, clamping it to the curvilinear surface, one tie being used to bend the hose approximately 90.degree. and both used for a bend of approximately 180.degree..
