  • Patent number: 5114168
    Abstract: An improved boat trailer for enabling a single operator to load and unload marine craft. The boat trailer includes an extendible tongue allowing it to be submersed by a conventional motor vehicle. The trailer includes laterally separated guide posts adjacent the rear of the trailer and a forward sliding mooring hook assembly. When the trailer is backed into the water, the boat is free to float off the trailer as a slide member supporting the front end of the boat slides upwardly along a slide channel. When loading the boat onto the trailer, the boat is moved into position over the trailer and the fore end of the boat is fastened to the slide member. As the boat is withdrawn from the water, the boat settles onto the trailer in registry with supporting members being guided by the freely moving slide member and the laterally separated guide posts.

  • Patent number: 4738358
    Abstract: A paint roller cover container and extractor assembly which simplifies the cleanup procedures when painting with a conventional paint roller. The container enables the roller cover to be stored therein and a core member is provided to displace the inside cavity of the roller cover. Once the roller cover and core are in position within the container, a small amount of paint or other liquid can be poured therein to saturate the roller cover. A sealing cap is put on the container to enclose it, thereby retaining the roller cover in a condition for reuse. Preferably, the container defines a plurality of radially inwardly deformed annular ribs which enable the container to be squeezed against the roller cover such that it is frictionally engaged, thereby enabling the associated roller handle portion to be withdrawn from the roller cover. The ribs also serve to centrally position the roller cover within the container, allowing liquid to be evenly distributed around the outer surface of the cover.

  • Patent number: 4649813
    Abstract: An improved trash receptacle is provided according to this invention. The invention is particularly directed to trash containers of the type having a top assembly having a frame and a pivoting door which encloses a central opening of the frame. The improvement comprises a pivot means for the door including a pivot member and a socket which enable the door to be retained in its normal position by gravity, but which permits the door to be easily detached from the frame to enable it to be inserted into the trash container to compress material therein. Once the user has completed the compaction step, the door is re-engaged with the frame.

  • Patent number: 4593615
    Abstract: An improved trash receptacle is provided according to this invention. This invention is particularly directed to trash containers of the type having a top assembly which attaches to the open perimeter of a container wherein the top assembly pivotably mounts a swinging door which permits access to the interior cavity of the container. The improvement comprises the addition of releasable pivot means permitting the door to be released from its pivotable engagement with the top frame such that the top can be pushed downwardly into the interior cavity of the container by the user, thereby compacting trash material therein. Once the user has completed the compaction step, the door is re-engageable with the top frame.

  • Patent number: 4416197
    Abstract: Apparatus for compacting waste material. The apparatus includes a over adapted to close the open end of a waste container. The cover includes a lip member adapted to engage the top ends of the container. The lip member has a central aperture formed therein. A cover member having a shape proximate the shape of the central aperture in the lip member is removably supported on the lip member to close the central aperture. The cover member is adapted to be inserted through the central aperture in the lip member into the interior of the container and urged downward to compact the contents of the container.
