The other member 21 has a hat base 32 provided at one end thereof with an upturned jaw 33 having a notch 33’ and laterally projecting prongs 34. The major poré tion of the base 32 ‘is made sufficiently narrow as to be received withinithe opening 29 of the member 23 when the two members are assembled together, and permit longitudinal sliding move ment of the plate 28’rela‘tive thereto. Thus the opposing jaws 30 and 33 are readily adjustable toward and from each other upon sliding move ment of the plate 28. The clasp members are positioned upon the upper face of the correspond ing spacer ‘and the base 32 is secured in a selected position thereon by any suitable means such as a bolt 35 that is applied through an opening 38 in the base and through a selected one of the perforations It in the spacer and also through Fig. 'l is a perspective view of an adjustable the upper end of ‘the corresponding stool ll.
