Abstract:
1. An apparatus for setting the spacing of a free standing range from a floor, the free standing range having an aperture for threaded mounting of the apparatus, the floor spacing setting apparatus comprising: a bolt having threads with the threads delimiting a helical path; a foot at one end of the bolt for resting on the floor; a winding follower that threads onto the bolt when the bolt is rotated into the aperture of the free standing range; and only a single nip formed on the bolt, the single nip being formed between the threads of the bolt at a single location of the helical path through which the winding follower passes as the bolt is rotated into the aperture of the free standing range, whereby, once the winding follower and the bolt have been threaded together, the bolt can then only be unthreaded from the free standing range by guiding the winding follower through the nip.
