Abstract: A hand held power driven sweeper that is supported on brush assemblies. The brush assemblies are horizontally mounted on the end of a handle component. The brush assemblies are readily mounted and removed from the handle component. A power component on the opposite end of the hand component provides motive power for the brush assemblies. The brush assemblies have bristles selected from a diameter and length range to provide a bristle density that provides a desired sweeping action as well as support for the sweeper. The bristles are of the type that will have a slight break over to produce the sweeping action.

Abstract: A dropout for a bicycle receiving tube includes an integral consumable ring which is melted upon the application of heat thereto to form a weld joint between the tube and the dropout. A one-piece dropout for a front axle includes a cylindrical mounting portion, a slotted front portion, and a tapered transition portion. The dropout can be cast or machined from a single piece of barstock such that the slotted front portion is offset radially inwardly relative to a largest outer diameter of the dropout. A three-piece dropout for receiving a rear axle includes two transition elements and a slotted plate welded to the transition elements.
