Abstract: An apparatus for facilitating the laying of floor boards on a subfloor includes a base member having an arrangement of subfloor engaging spikes provided on its bottom surface for anchoring the device during operation. A floor engaging member for engaging the floor board being laid is also provided. A handle and yoke assembly is pivotally mounted on the base member in order to operate the floor engaging member, and a transmitting arrangement is connected to the floor board engaging member for transmitting the pivoting movement of the handle and yoke assembly into sliding movement of the floor board engaging member. Additionally, the apparatus is provided with an arrangement that is connected to the base member for preventing the transmitting arrangement from being forced upwardly during operation of the apparatus.
