  • Patent number: 8794898
    Abstract: A hand-operated hay bale cart has only two wheels connected in a laterally spaced-apart fashion to a generally rectangular handle frame. The handle frame is generally near the top, or above, the wheels, creating an open space beneath the frame and between the wheels for receiving a bale of animal feed. Pivotally supported by the handle frame is a securement rack that swings freely on a horizontal axis and includes a set of curved hooks at or near both the front and back of the securement rack. A hook handle operates the hooks to rotate relative to the rack to impale the hay bale. The securement rack, if it is allowed to rotate freely, including when it has impaled and secured a bale of hay, may balance the lifted bale of hay between the two wheels for convenient transport.

    Abstract: A hand truck for moving logs or other heavy material is disclosed. The hand truck includes a frame having a first section for being gripped by a user to manipulate and push the hand truck. The second section defines a carriage extending outwardly from the first section. The carriage serves as a loading platform for holding and supporting material such as a log loaded thereon. A pair of wheels are provided to enable ready movement of the hand truck over a supported surface such as the ground. To facilitate loading and storing a log during transportation, a loading strap is provided upon which a log can be rolled. The outermost end portion of the strap can then be gripped and moved towards the hand truck to enable movement of the log along the strap as it is advanced towards the carriage for storage and transportation.

    Abstract: This is a lifting mechanism especially suited to move a stack of paper to a height so that it is easier to remove or work with. The lifting mechanism has as a bottom portion a tilting platform that receives and holds a paper stack and its support. This tilting platform will be tilted in a front down position prior to and during loading of the paper stack thereon, and will automatically tilt down at its back portion when stack loaded. This is because the fulcrum of the tilting platform is located nearer the front sections of the platform than it is to the back section of the platform. When the weight of the paper stack acts upon the tilting platform, it will force the platform down at its back portion.

The handtruck engages and locks into the cabinet with the water bottle in proper, tilted position. A suction tube is dropped straight down into the bottle so that it reaches the lowest corner of the bottle. The suction tube carries a pump and discharge spout so that actuation of the pump causes dispensing of water.
