Abstract: A light weight track system for a buoyant amphibious vehicle, the vehicle having two pontoons, the pontoons having a flat horizontal top surface and a flat horizontal bottom surface, each end of the flat horizontal top surface and the flat horizontal bottom surface being connected by a flat inclined surface, the track system including a plurality of treads connected by a single continuous drive chain assembly around the outside of each of the pontoons, the flat horizontal top surface and the flat horizontal bottom surface having a channel therein for rotatable receipt of the drive chain assembly, the drive chain assembly including a plurality of rotatable drive rollers connected to the treads and connected to adjacent drive rollers by links to form a continuous drive chain extending completely around the outer surface of each of the pontoons, each tread having an idler roller connected at each end thereof which contacts the surface of the pontoon to support the tread.

Abstract: A support apparatus for stacking bottles of water in a vertical fashion one atop the other includes a bottom support having an inclined side wall with a lower annular rim that fits against the top end portion of a lowermost bottle. An upper support registers with the bottom support and includes a plurality of radially extending struts that provide a surface for conforming to the bottom of an uppermost bottle.

Abstract: A wheeled transporting device for use in carrying large five-gallon bottled water containers uses an improved frame configuration that cradles one or more of the bottles between appendages that extend outwardly, horizontally of the frame when the frame is vertically positioned.

Abstract: A method and apparatus for cutting trees and bushes including a circular disk having cutting teeth connected thereto, a motor for rotating the disk and an arm connected to the motor for moving the disk into contact with trees and bushes.

Abstract: A dispenser for housing large (for example, 5-gallon) bottled drinking water containers having a generally narrow mouth (for example, 1-2 inches in diameter) provides a cabinet having a lower end portion adapted to receive the bottle in an upright fashion so that the flat base of the bottle sits upon the lower floor portion of the cabinet and the upper open-mouth portion extends upwardly. A pump suctions water from the bottle and transmits it to a first reservoir positioned at the uppermost portion of the cabinet. The first reservoir is an ambient temperature reservoir for containing ambient temperature water such as is typically used in cooking or the like. A second cold water reservoir is contained generally below the first reservoir and receives flow therefrom via a duct which extends through the central portion of the second reservoir. The duct transmits ambient water to the second reservoir and beyond to a spigot which is affixed to the external cabinet portion of the apparatus.

Abstract: A closure assembly for conveying air to the interior of an inverted water bottle and for conveying water from the interior of an inverted water bottle having a downwardly pointing spout including a closure connectable to the spout of a water bottle, the closure having an opening therein through which water may flow from the inverted water bottle, a hollow cylinder having an open first end and a partially closed second end, the first end being connected to the closure, the second end being located in the interior of the water bottle and having an air inlet for conveying air from the interior of the hollow cylinder to the interior of the water bottle, the second end having a water inlet for conveying water from the interior of the inverted water bottle to the interior of the cylinder the closure having an opening therein in alignment with first end of the hollow cylinder, and a float slidably received in the cylinder for sealing the water inlet.

Abstract: A warm air deflector which is connectable to the outside of the radiator housing of a vehicle in which air is blown in a forward direction over the radiator and out the front of radiator. It includes a curved front plate generally located on the upper half of the radiator and extending above the top of the radiator. The curved plate is generally concave with the concave portion facing toward the driver. Connected to each side of the curved plate are two parallel side walls having their inner edges generally parallel to the radiator of the vehicle and their outer edges terminating along the edge of the curved plate, the curved plate having a series of holes on the lower portion thereof and a slidable baffle for selectively covering the holes. The slidable baffle may be lowered to divert air into the diverter and back onto the operator or raised to allow air to flow through the radiator and through the holes in the curved plate without being diverted backward onto the driver.

Abstract: A projectable guard for a projectable lawn sprinkler for preventing foreign matter from entering the sprinker. The sprinklers to which the projectable guard is attached automatically rise from the ground when water pressure is applied thereto. The sprinklers have a housing, a pipe rigidly connected to the housing, a projectable conduit connected to the pipe, and a sprinkler head attached to the projectable conduit. The boot connects to the housing and the projectable pipe to prevent grass, leaves, sand, dirt, and the like from entering the housing.

Abstract: High rising projectable sprinklers which rise automatically from the ground when water is supplied under pressure to the sprinklers. The projectable sprinklers include a generally cylindrical housing closed at the bottom and sunken in the ground, a projectable float which floats upward within the housing when water is supplied under pressure to the sprinkler, and a sprinkler head including a rotating nozzle or nozzles attached to the top of the float.

Abstract: A method and apparatus for controlling the tension of flexible drive belts, or a single drive belt, connecting a drive pulley to a driven pulley. The apparatus includes a first idler assembly for engaging the slack run of the drive belts, a second idler assembly for engaging the drive run of the drive belts, and a tension member for adjusting the distance between the first idler assembly and the second idler assembly to a distance sufficient to cause the apparatus to maintain a position between the drive pulley and the driven pulley. The apparatus requires no external support or positioning member to maintain the position of the apparatus on the belts while the apparatus is controlling the tension of the moving belts. The method includes placing a first idler assembly on the slack run of the drive belts, placing a second idler assembly on the drive run of the drive belts, and forcing the assemblies together to increase the tension of the drive belts.

Abstract: A lawn sprinkler adapted for spreading chemicals over a broad area. The sprinkler includes a pump for pumping fluid solutions, suspensions, or mixtures of chemicals through the nozzle of the sprinkler.

Abstract: Projectable sprinklers which rise automatically from the ground when water is supplied under pressure to the sprinklers, sprinkler heads, stationary sprinklers employing the sprinkler head of the present invention for use on the surface of the ground, and a lid apparatus for increasing the area wetted by a sprinkler head. The projectable sprinklers include a generally cylindrical housing closed at the bottom and sunken in the ground, a projectable float which floats upward within the housing when water is supplied under pressure to the sprinkler, and a sprinkler head including a rotating nozzle or nozzles attached to the top of the float. In one embodiment, the projectable sprinkler contains means for spreading chemicals over the surface of the ground. The sprinkler heads include means for pumping solutions or liquid mixtures of chemicals through the nozzle or nozzles of the sprinkler head, and may be used in a stationary or projectable sprinkler system.
