DEFINITION

Classification: 402/37

(under subclass 36) Device wherein the oppositely disposed sheet retainer are acted upon by a toggle joint means to bias the retainers against rotational travel.

(1) Note. The term TOGGLE JOINT as used in the above definition, is defined as two bodies jointed together end-to-end or edge-to-edge in a nonplanar relation (or the equivalent thereof), so that when a force is applied tending to bring the bodies into a coplanar relation, any member abutting or jointed to the distal end thereof will tend to be forced apart.
