Abstract: An improved bugle call having an improved mouthpiece. The mouthpiece is constructed of an acrylic and configured to optimize back pressure blown into the mouthpiece. The acrylic construction significantly improves the harmonics of the bugle tube, allowing the user to simulate the sound of a bull elk bugling. The bugle tube is utilized with a reed to produce sound. The reed is preferably positioned in the user's mouth and operated as what is traditionally called an external reed call. The use of acrylic for the mouthpiece has produced a dramatically improved sound compared to traditional, known bugle tubes.

Abstract: A unitary mattress assembly comprises a plurality of coil springs interarranged to define a single innerspring core having a generally rectangular shape in plan. The core has a first portion which is sized to accommodate a first sleeping person and comprises coil springs having a first preselected compressive strength. Adjacent to the first portion is a second core portion sized to accommodate another sleeping person and having coil springs of a different compressive strength than the springs of the first portion. By the foregoing construction, a mattress may be manufactured having a single innerspring core but having two regions of differing firmness to suit the particular preferences of two people.

Abstract: A mattress spring core having a plurality of zones of differing firmnesses due to different characteristics of helical lacing connectors within the particular zones. The spring core has a plurality of identical coil springs arranged in side-by-side transversely extending rows and columns. The coil springs are connected together at the upper and lower ends of the springs with helical lacing connectors which encircle a portion of the upper and lower faces of the springs. The helical lacing connectors may be of a heavier gauge wire in one or more zones of the mattress spring core thus causing that particular zone to be of an increased firmness relative to the other zones of the mattress. Alternatively, the helical lacing connectors within a zone may comprise two or more co-axial lacing wires to impart greater strength or rigidity to one or more zones of the mattress.
