  • Publication number: 20110049207
    Abstract: A hitch mounted cargo carrier including a hitch member having a horizontal rail adapted to be secured in a hitch and a vertical rail and a carrier member movable relative to the hitch member between a transport position and a loading position. The vertical rail includes an aperture therethrough. The carrier member includes a sleeve slidably positioned around the vertical rail and movable relative thereto, a platform adapted to carry cargo, and a pair of brackets defining a channel. The brackets each have a teardrop shaped opening therethrough. A pin is received through the teardrop openings and the aperture through the vertical rail when the carrier member is in the transport position to secure the carrier member relative to the hitch member and prevent swaying of the platform.

  • Patent number: 5853336
    Abstract: A golf club handle support for keeping handles of golf clubs lying on the ground in a raised position above the ground. The handle support comprises a stiff sheet defining a central foldline to form sidewalls on each side of the foldline. This permits the sheet to assume a substantially inverted V-shape in cross section so that the remote edges parallel to the foldline may engage the ground and a golf club may rest on the sidewalls at or adjacent to the foldline.

  • Patent number: 4993642
    Abstract: An improved spray nozzle for use with air atomizable liquids wherein the spray pattern created by the atomizing nozzle may be adjusted from a circular pattern to a flat pattern or alternatively to an open oval, the open end facing in preselected directions, the adjustments being capable of occurring during the continuous operation of the nozzle. The body of the gun is formed of molded plastic parts bolted together. Fluid control components incorporated into cavities in the molded gun body are easily removable and replaceable to facilitate repair and cleaning of the gun.

  • Patent number: 4869641
    Abstract: A compressor driven by a motor delivers air under pressure to a plurality of paint spray guns. An air circulation fan is incorporated with the motor to cool the apparatus during operation. The compressor shaft includes bearings on each end and the bearing on the lower end is physically separated from the lower end of the compressor to prevent oil contamination of the air being discharged. A pump is associated with the separated bearing which delivers oil to lubricate the bearing when the compressor is in operation.
