Abstract: A gripping device including a pair of side assemblies, each having a substantially constant arcuate cross-sectional configuration throughout its length, projections on its concave inner surface, and free outer edges while their inner edges are hingedly connected together by a hinge to enable said outer edges to be moved towards or away from one another. One said side assembly has along its inner edge a channel and the other is provided with a bead along its inner edge which is pivotally engageable within said channel by relative longitudinal sliding movement therebetween. A torsion-bar spring assembly is disposed adjacent the hinge and connected at its opposite ends into a recess in the respective side assembly and adapted to urge the said side assemblies apart. The parts are so made and arranged that said device may be held within a cupped hand of a user with the outer edges remote from the palm of the hand and disposed substantially parallel to the pivot axis of the user's hand.

Abstract: A serving tray, having an opening through which at least a portion of the server's hand may be inserted and a support which thrusts upwardly against the wrist and/or forearm materially assists in carrying and balancing the laden tray, has utility for use in situations in which the server must carry and serve from the tray with one hand.
