One ’object of the invention is to provide a
bracelet structure of this character which is cal0 pable of being readily constructed at a relatively
small cost, and -one in which the parts are
tially along the line 6-6 of Fig. 5.
VIn the embodiment of the invention illustrated
herewith .I designates generally a bracelet struc- 10
