Abstract: A knockdown, but sturdy, cabinet for campers is disclosed. The cabinet can be quickly assembled at a campsite by first attaching a pair of sidewalls to the inside of a weatherproof covering so that the sidewalls are spaced apart and parallel to one another. The sidewalls have opposed inner surfaces with transverse grooves so that a plurality of shelves can then be slid between the sidewalls and into the grooves to complete the cabinet. When breaking camp, the cabinet can be easily broken down by sliding the shelves out of the grooves and then detaching the covering from the sidewalls. The shelves, sidewalls and covering can then be stacked and stored in a small box so as to take up little space during the trip home.

Abstract: A heat-sink type of water heater unit is disclosed wherein the unit is designed for external installation on a stove to transfer heat from the stove to water flowing through the unit, to pre-heat the water for subsequent use. The unit has a flat surface which can be bolted to the outside of the stove, an inlet which can be attached to a cold-water source, a U-shaped inner passage in which water can flow and be heated by the stove, and a discharge which can be hooked up to a hot-water tank. In addition, the unit has an adjustment feature which enables the unit to be moved laterally, closer to or farther away from the hot stove wall to which the unit is connected. By regulating the distance between the unit and the stove, the water temperature produced by the unit can be selectively controlled.

Abstract: A portable log splitting machine is disclosed wherein the splitter can be readily broken down into separate lightweight components for convenient transport and storage, such as in the trunk of an automobile. The splitter includes a ram section comprising an elongated beam with a wedge fitted at one end and a slidably-mounted pusher plate or ram which is hydraulically operated to drive a log against the wedge to split the same. The ram is reciprocably moved by the piston rod of a double-acting hydraulic cylinder. The rod is detachably connected to the ram by a simple yoke and cross pin arrangement and the cylinder is detachably fitted onto the beam by a trunnion pin that extends from the cylinder and slips into brackets carried by the beam for ready assembly and disassembly. An engine-driven pump assembly is connected to the cylinder by two detachable hoses and provides the hydraulic pressure for the cylinder.
