  • Patent number: 4962635
    Abstract: A power trimmer including a handle, a housing, a gas operated engine, a plurality of wheels, and a cutting blade. The housing includes a front wheel mounting member, a rear wheel mounting member, and a cutting blade mounting member. The cutting blade mounting member is offset from the front and rear wheel mounting members. A passageway extends along the upper surface of the cutting blade mounting member. The first end of the passageway is positioned adjacent the exhaust port of the gas operated engine. The second end abuts the rear wheel mounting member. The passageway directs the exhaust fumes from the gas operated engine underneath the housing thereby significantly reducing the noise of the invention. Further, harmful exhaust fumes are directed away from the operator. The cutting blade mounting member includes fixed and removable sections. The removable section can be secured to either side of the fixed section. Thus, an operator can trim from both sides of the power trimmer.

  • Patent number: 4558838
    Abstract: A novel end bracket for the ends of each of several wood cross bars that support the shelf decking in a storage rack, and a storage rack incorporating the same. The end bracket has a rigid main rectangular plate with a thin, flat, rigid supporting tongue extending rigidly outward from one side of the plate for a substantial distance beyond the cross bar end. A rigid flange extends downward from each end of the main rectangular plate for embracing the cross bar end. A rigid finger extends inward at the bottom of each of the flanges, at a slight obtuse angle to the flange, for confining the cross bar end. At least one rigid hook member extends inward at the bottom of each flange, with a rigid tapered tip oriented at an acute angle to the shank of the hook member, for fixedly securing the end bracket to the cross bar by driving the hook into the cross bar.
