Abstract: In general, mobile agricultural sprinkler machines can be used on smooth terrain only or under conditions permitting travel in a straight line. The apparatus of the present invention is a high pressure, self-propelled, mobile sprinkler which can take a circuitous route over rough terrain. Moreover, the apparatus of the present invention includes several safety features which reduce the likelihood of equipment damage. The safety features include an automatic drive stopping system which halts the sprinkler at a predetermined location. Also provided is a drive shutoff which is engaged if the hose of the apparatus become tangled. The invention also includes a brake for slowing the apparatus as it becomes lighter to prevent the apparatus lurching forward, thereby avoiding the problems of hose tangles and uneven water distribution.

Abstract: A system for thoroughly spraying buildings with a pesticide. A truck carries a tank of liquid pesticide, a hose on a reel and a pump for pumping pesticide into the hose. A cart including a tube having a first end for connection to the hose and a second end carrying one or more spray heads is placed at the far end of a building with the hose extending the length of the building and out a door to the truck. The tube is mounted on at least two wheels, with a sled member supporting the end of the tube adjacent to the hose connection. The spray heads produce a pattern in approximately a vertical plane perpendicular to the length of the tube and hose. As the hose is reeled up, the cart is pulled across the floor of the building, with the fan-like spray pattern fully treating the building interior.

Abstract: A wheeled vehicle carries a reel 3 on to which part of a long length of hose may be coiled, with the end of the hose coupled to a hose connection 10 which conveys water to a hollow axle 7 about which the reel 3 rotates and through a swivel coupling 12 to a hollow shaft 13 from which the water flows through shorter hoses 16, mounted on long arms 14, to nozzles 17. Passage of the water from the nozzles causes the arms 14 to rotate about a vertical or nearly vertical axis and this rotation is transmitted to the reel 3 which rotates. Rotation of the reel 3, which is preferably disposed with its axis vertical, causes more of the hose to become coiled on the reel and this in turn causes the vehicle to move along the ground.

The machine also includes a pressure sensor (40) at the water inlet to the machine. The computer is programmed to calculate the ideal speed of displacement of the sprinkler gun (3) as a function of the depth of water to be delivered and of the water flow rate which it calculates on the basis of the pressure of which is measured, with the computer also being programmed to calculate the ideal duration of an actuator cycle.

Abstract: The present invention relates to brushfire fighting equipment and more particularly to a portable brushfire hydrant which can be easily stored and maintained in a condition for immediate use by an individual homeowner to protect his life and property from brushfire damage. In the past, individual home- owners could only utilize the commonly available garden hose which, of course, is grossly inadequate for the purpose or if a self-contained engine driven auxillary pump is available, it is usually not maintained or stored with all the accessory equipment necessary for the immediate and effective use in such fire fighting emergencies. The present invention successfully overcomes these deficiencies by providing a completely portable brushfire hydrant which has an open frame on which a high pressure pump can be securely mounted with all the accessories necessary conveniently disposed in a tightly compact storage condition on the frame for connection to and immediate use with the pump on a moment's notice.

Abstract: A hose-drum irrigation machine having a tensioning device engaging the hose at a position adjacent the hose-guide by which the hose is pulled from the drum as the hose is being unwound or by which a drag is applied to the hose as it is being re-wound on the drum, thereby to prevent the convolutions of hose on the drum from becoming loose. The tensioning device comprises an endless belt of which one run extends lengthwise of the hose adjacent the hose-guide and frictionally engages the hose thereby to pull it from the drum where the hose is being unwound or to exert drag when the hose is being re-wound. The belt is driven in the appropriate direction by a driving sprocket driven by a motor.
