Patent number: 9745760Abstract: 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.Type: GrantFiled: November 17, 2014Date of Patent: August 29, 2017Inventor: Oscar Pereyra

Patent number: 7818844Abstract: 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.Type: GrantFiled: May 20, 2008Date of Patent: October 26, 2010Inventor: Antoni Wolan

Patent number: 7784143Abstract: The present invention is directed generally to tools that are made, at least in part, more durable, particularly one or more working surface(s) of the tools. For example, various tools such as trowels, knives, and scrappers may be made having at least a portion of their blades heat treated to make at least their working edges more durable and extend their useful lives. For example, in one embodiment, a trowel blade may have at least one texturing edge that has been at least partially heat treated.Type: GrantFiled: March 9, 2006Date of Patent: August 31, 2010Inventor: Scott A.

Patent number: 7730575Abstract: 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.Type: GrantFiled: January 19, 2006Date of Patent: June 8, 2010Inventor: Chin-Chen Huang
