Abstract: Bulb edges are severed from a glass sheet. At least one score is imposed along and adjacent to the bulb edge, and the scores are sequentially opened by mechanically running the score. A pair of powered and jointly actuated, simultaneously moving cylindrical mandrels apply torque about the trailing end of the score line to sever the sheet. The lower mandrel moves in an upward direction beneath the sheet while the upper mandrel moves through an arcuate path down and toward the bulb edge. A method of severing bulb edges from a glass sheet is also disclosed in which the scores are opened by applying torque about the score line on the upper and lower edges of the trailing end of a glass sheet.

Abstract: An improved vehicle seat for a vehicle propelled by leg action of the rider includes a seat portion that is divided into a right half and a left half. Both halves of the seat portion are pivotally affixed to a seat post that is adapted to be rigidly affixed to the vehicle. The front portions of the right half and the left half of the seat are adapted to move upwardly and downwardly. A suitable coupling apparatus engages the right half and the left half of the seat whereby the front portions of the right half and the left half of the seat move upwardly and downwardly simultaneously in opposite directions relative to each other as the rider propels the vehicle.
