Abstract: A movable fitting member such as a bathtub drain stopper can be constructed so as to be useful with different drain fittings which differ by having post holders with different sized openings into which a guide post can be threaded. Such a movable fitting member is constructed so as to use a body having a sleeve located around a post holder and having an enlarged cavity around the post holder within the body. The guide post used is double ended; one end is threaded into the post holder in a drain fitting and the other end is located within the cavity. A nut is located on this other end; it is sufficiently large so that it cannot pass through the sleeve. As a result of this the body cannot normally be separated from the guide post during the use of the fitting member.

Abstract: An escutcheon component system which fits around a pipe at the point wherein the pipe projects through a wall includes an escutcheon plate and a generally cylindrical insert. At least the periphery of the back side of the escutcheon plate is capable of abutting against the wall. A hole through the escutcheon plate is sized so that a pipe can pass through it. An annular flange extends outwardly from the back side of the escutcheon plate co-cylindrically with the hole. The insert is formed of a flexible material such that it is capable of being compressed and inserted into the interior of the flange. An opening through the center of the insert allows the insert to be passed over the pipe, and when located around the pipe the insert will grip the pipe if the insert is then compressed within the interior of the flange. When the insert is located around the pipe and within the flange frictional forces hold the escutcheon component system to the pipe.

Abstract: A device for suspending plumbing components such as a pipe elbow or a high ear 90 elbow between the studs of a wall and retarding propagation of sound between the plumbing components and the wall has a main body or housing formed of a semi-resilient material which is incapable of transmitting a sound from a first location in this body to a second location also in the body. A first member which attaches to the wall or a strip of plumbers tape extending between the studs is attached to the body at the first location. A second member which attaches to the plumbing components is attached to the body at the second location. The first and second members are connected to the body at their respective locations such that a parallel portion of the first member is parallel with, but is not coplanar with, a parallel portion of the second member.

Abstract: A sound insulating support member for isolating a plumbing pipe or other tubular member from a support surface includes an insert member formed of a material substantially incapable of transmitting sound vibrations and sized to be capable of encircling the pipe or tubular member. The insert member fits within a sleeve member which is formed of a semiresilient material capable of maintaining its shape at rest but capable of being flexed when subjected to a force. Both the sleeve member and the insert member contain a slit. The insert member is retained within the sleeve member such that the slit of the insert member is aligned with the slit of the sleeve member and when both the sleeve and the insert are open the pipe or tubular member can be inserted through the slits and the sleeve and insert close around the pipe or tubular member to cradle the tubular member within the insert which in turn is fixedly held within the sleeve.
