First Claim
Patent Images
1. A pair of parts to be joined together for pivotal movement, the combination therewith of(1) a plurality of spring pivots, each spring pivot including:
- a. a pair of pivot plates in face to face contact, and each plate having a wing or tab for attachment to the parts respectively;
b. a pair of Belville spring washers encompassing said pivot plates;
c. a hollow rivet extending through aligned holes in said pivot plates and said spring washers, said rivet having heads confining said parts in a stack and loading said spring washers so that substantial frictional resistance is imposed against relative angular movement of said parts;
d. said attaching wings or tabs extending radially beyond said spring washers; and
(2) a rod extending in slidably fitted relationship through the hollow rivets to hold said spring pivots in coaxial relationship while said wings or tabs are attached to said parts, said rod being slidably removable from said spring pivots;
(3) said spring pivots being joined to each other only through said parts when said rod is removed;
said spring pivots confining said parts for angular movement about the common axis of said spring pivots.

Abstract
A spring pivot joint comprises two face plates with heavy serrations or ribs between them, both sandwiched between Belville springs or spring washers, the washers being held in a strongly stressed condition by a hollow rivet. The face plates have integral wings or tabs extending radially beyond the washers for attachment to the companion mannequin parts to be jointed. Since the rivets are hollow, a simple rod can extend through a plurality of them to hold them in coaxial alignment while being attached to the jointed mannequin parts.
