Abstract: A pull start assist device may include a frame with a base and a longitudinal member. The longitudinal member may include a first pivot axis and a second pivot axis displaced from the first pivot axis. The device may also include a pedal arm with a pedal on a first end and a second end pivotally coupled to the first pivot axis of the longitudinal member. A swing arm may be provided with a handle receiver on a first end and a second end pivotally coupled to the second pivot axis of the longitudinal member. A connection link maybe used to connect the swing arm and the pedal arm, whereby a pull start handle of a powered tool may be supported by the handle receiver and the pedal displaced by the foot of a user, actuating the swing arm and starting the powered tool.

Abstract: An adjustable duct start collar may include a base with a flange on a first end of the base and a plurality of tabs on a second end of the base. The base may be constructed of a material of substantially uniform thickness and include at least two slots in the base. The first of the slots may be positioned substantially parallel to a second of the at least two slots. Each of the slots of the at least two slots being able to independently receive the flange, whereby when the base is curved into a cylindrical shape with the flange positioned in the first of at least two slots, the curved base will form a cylindrical shape with a first diameter and when the flange is positioned in the second of the at least two slots, the curved base will form a cylindrical shape with a second diameter.

Abstract: The disclosed invention is a method and device for removing dirt and other debris from an open trench. The invention includes a tool with an elongated handle and a blade attached thereto. The blade is cantilevered from the support to allow positioning of dirt and other debris thereon. The combination creates an elongated shovel with a substantially flat bottom edge, so as to conform to the bottom of the trench. The handle and blade make a slightly acute angle one to another, with the center of gravity of the combination being below the handle when the handle is in a substantially vertical position and the placement of debris on the blade making little if any movement of that center of gravity. This method allows the user to stand directly over an open trench and remove soil with the tool with minimal displacement of the weight of the combination from the body of the user. This minimal displacement results in minimizing lower back stress while performing the task.
