Abstract
Abstract A combination hand truck and tool for use in installing floor coverings of the glued-down type, such as carpet or linoleum utilizes the weight of the installer's tool box for pressing the floor covering to the floor, in lieu of a weighted roller ordinarily carried by the installer. Retractable wheels and a pivotable, adjustable position handle enable the device to be used as either a press, riding on glides that contact the floor covering, or as a hand truck for carrying the installer's tools and supplies.
