Abstract: A chair support shell has an integral back portion, seat portion, and joining portion between the back portion and the seat portion. At least a major portion of the support shell comprises a compliant structure, the compliant structure having a plurality of cells interconnected by a plurality of resilient members. The compliant structure provides compliance in the seat portion, compliance in the back portion, and compliance in the joining portion. The compliant structure enables recline of the back portion relative to the seat portion.

Abstract: A frame assembly for supporting a paint booth that includes a paint application chamber and a reclamation tank. A plurality of frame posts is spaced apart and affixed to a base floor. Opposing support members, each having a shell, are arranged end to end in a parallel column. Each of the shells is affixed to the upper end of at least two of the frame posts. The support member includes a horizontal structural element affixed longitudinally inside the shell, and at least one vertical support element affixed to the horizontal structural element inside the shell. Each of the shells forms a section of the reclamation tank and provides support to a section of the paint application chamber allowing the paint booth to be installed independently of a building that houses the paint booth.

Abstract: This invention relates to a machine for harvesting market-size worms from their bedding that lays in the bottom of a flat-bottomed trough-like bed. The machine is self-propelled and travels lengthwise of the beds riding atop their side walls. A novel digger is provided on the front end of the unit made up of a rotating reel with rake-forming tined shafts, the tines of which remain in parallel relation at all times due to a pair of independently rotating eccentrically positioned hubs that rotate in unison therewith and are operatively connected thereto by a series of parallel links. The digger rakes the bedding along with the worms contained therein back onto a conveyor belt that carries the mixture upwardly and rearwardly and deposits it onto a shaker screen inclined downwardly and rearwardly above the open trough.
