Abstract
Abstract A handle assembly for attaching a decorative handle to a turning stem is disclosed. In one embodiment, a stem cap having outer and inner spline surfaces, a stop surface, and carrying surface is placed over a turning stem, and the stem cap is secured to the turning stem using an attachment screw. A handle knob having interior mating splines is then brought down upon the top of the stem cap and an assembly ring is brought up from under the stem cap thereby sandwiching the stem cap. The handle knob and assembly ring are then connected, thereby completing the construction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A valve handle assembly attachable to a rotatable valve stem comprising: A stem cap that fits on the valve stem and is fixed axially relative thereto to rotate therewith, having an outer transversely facing surface configuration, a stop surface facing in one direction along said valve stem, and a support surface facing in the opposite direction along said valve stem; a valve handle surrounding said stem cap having an inner transversely facing surfacing mating with said configuration for rotation with said stem cap and having an abutment surface seated against said stem cap support surface; and a mounting member around the valve stem, in threaded engagement with said valve handle, which moves relatively to said valve handle along said valve stem upon an assembly of the mounting member with said valve handle by working of said threaded engagement, said mounting member having a seating surface for seating against said stop surface of said stem cap for holding said stem cap between said handle and said mounting member.
Claim 2
Dependent Claim
