Abstract
Abstract An adjustable valve handle is disclosed which permits wide variation in location of a recessed plumbing fixture relative to the wall behind which it is placed. This wide range of adjustment is accomplished utilizing a stem over which a handle with an elongated bore is placed. Securing means in the handle permits placement of the handle at numerous locations along the stem without the necessity of cutting, breaking off or otherwise altering the stem.

Claim 1
Independent Claim
178 words
An adjustable valve operator for use with a valve recessed in a wall, comprising a valve body capable of being located inside the wall at varying distances from the outer surface of the wall, a valve stem extending from the valve body at varying distances beyond the outer surface of the wall depending upon the location of the valve body, the valve stem having splines along its length and non-frangible, spaced circumferential grooves thereon which interrupt the splines at regular spaced intervals on the stem, a handle slidable onto said stem having an elongated bore therein to facilitate substantial movement of the handle relative to the stem and placement of the handle close to the outer surface of the wall and threaded securing means located in a threaded bore in the handle aligned transverse of the stem, the securing means having an inner tapered surface arranged for mating engagement with the outer surface of one of the circumferential grooves on the stem whereby the handle can be affixed to the stem in close proximity to the outer wall.
