Abstract A conveyor and a conveyor in combination with an invalid bed. The conveyor is made up of a continuous belt supported on two spaced pulleys. The pulleys have an outside periphery in the shape of a polygon, rotatable about a central axis and having flattened surfaces around the periphery, each flattened surface being equal in length to one side of the polygon. The belt is made up of hinged sections, hinged together by links. Each link is pivoted at its ends to the ends of two adjacent sections and each section has teeth arranged in a circle having a center at the pivot point of the links. The teeth mesh with each other as the sections pass around the pulleys so that the sections are held in positive alignment with each other. The links are arranged to form a continuous belt that passes around the pulleys and each section is equal to one side of the polygonal surfaces of the pulleys. Each section has a pad on it that forms a bed mattress to support an invalid and the pulleys are supported on the head and foot of the bed.
A continuous conveyor belt made up of a plurality of laterally spaced pairs of sections, each section having a web portion abutting the end of a web portion of an adjacent section, said sections bEing of substantial depth, each section having a link pivotally connected to an adjacent section at a spaced position below the center line of said section, and teeth formed on the lower corners of each adjacent section, said teeth being arranged in a circle so the center is at the said pivot to said link whereby said teeth mesh with each other and hold said sections in parallel relation to each other.
