Abstract: A portable instrument holder for smaller instruments such as harmonicas is adapted for use with commonly available stands, such as microphone stands. This adapter is comprised of an adapter block that releasably engages an instrument holder. The adapter block fits onto the threaded upper end of the stand that is adjustable in height. The adapter block has a selection of threaded holes to fit various stand thread-types and stand diameters.

Abstract: A thread protector and tip scuffer for a breakdown billiard cue includes a separate protector member for each threaded end section of the cue, comprising either a threaded stud or a threaded bore. The protector member is thus either threadable over the stud projecting from the cue end section or into the threaded bore on the other cue end section such that the threads and adjoining faces of the cue sections are protected when disassembled from damage as a result of dropping of the like. The protractor members are threadable axially to one another when not in use and have cylindrical bodies to provide a smooth compact cylindrical assembly. A third end protector may be provided for a cue assembly having an interchangeable alternate tip section, and the additional end protector may be substantially identical to one of the basic two piece set and threadable into one end thereof when not in use.
