  • Patent number: 10704273
    Abstract: The present invention is a trowel having a blade with a rounded side edge, a straight side edge, and a notched edge between the rounded side edge and the straight side edge. The trowel may include a handle disposed opposite the notched edge and substantially parallel to the straight side edge, aligned with the plane of the blade. The blade may be made of a thin or flexible material, allowing the blade to be slightly deformed during use to create a consistent layer of adhesive. The rounded edge may be of a relatively smaller radius, allowing for a wider, shorter blade. In other embodiments, the rounded edge may be of a relatively bigger radius, allowing for a narrower, taller blade. The notched edge may be square notches, v-notches, u-notches, or other notch shapes according to user preference.

  • Patent number: 9745760
    Abstract: A bull float for leveling and finishing concrete made from two different materials is disclosed. In one embodiment, the main wooden base has an insert made from fiberglass. As the bull float is pushed forward, the pole is angled such that the wooden back edge levels and smooths the concrete, then on the return stroke the pole is raised such that the fiberglass front edge finishes the concrete as the bull float is swept back to the concrete worker. This bull float performs the tasks currently requiring three separate bull floats, thereby saving the worker from having to replace and clean two or three separate bull floats. As concrete sets up quickly, the time savings obtained through using just a single bull float results in superior concrete slabs with less effort required of the concrete worker and more time to work the concrete.

  • Patent number: 7818844
    Abstract: A hand trowel is provided with upstanding side and rear walls to prevent cement or grout from sliding off when scooped from a container. The sidewalls of the trowel taper to the front edge of the trowel so that no barrier is created to prevent the front edge from being utilized as a “finishing” edge. A handle extends from the rear wall of the trowel. The handle is provided with ergonomic indentations and the front edge is slanted to allow use by either a right- or a left-handed person.

  • Patent number: 7730575
    Abstract: The invention relates to a structure for a hand trowel handle with adjustable rotational angle on the grasping section. The hand trowel is composed of a blade, a connecting section and a grasping section. The connecting section uses its base to connect with the tongue on the blade. The structure for the grasping section with adjustable rotational angle features mainly in the radial toothed rings at the front end of the grasping section and at the supporting end of the connecting section. When the grasping section is worn on the shaft in the center if the radial toothed ring of the connecting section, the grasping section can be tightened or loosened through the adjustment knob, the spring and the shaft in the accommodating hole. Thus, the rotational angle between the grasping section and the shaft can be adjusted.
