Abstract: A quick and dry coupling for coupling together devices such as fluid lines. One embodiment of the coupling includes a pair of heads in which is provided mating members having mating surfaces for moving the mating members in opposite directions away from one another towards an open position and to permit movement of the mating members towards one another when the pair of mating members are turned in the opposite direction relative to one another, a latch coacting between the heads for selectively being movable to an unlatched position, to an intermediate position, and to a latched position for providing the attached condition of the coupling. Springs are provided for moving the pair of mating members into a closed position in which fluid flow is stopped and the latch is moved from the latched position to the intermediate position.

Abstract: A drive mechanism for driving a shaft in unison with a wheel. The drive mechanism includes a plurality of slave pistons and a like plurality of master pistons. Each slave piston is paired with a master piston to establish a plurality of paired pistons. A cam is operatively coupled to the wheel and to the master pistons to cause the master pistons to move between retracted and extended positions when the wheel is rotated.

Abstract: A detachable chemical sprayer for spraying a liquid chemical onto a field as said sprayer is moved over the field. The detachable sprayer includes a frame, structure attached to the frame for detachably mounting the frame on a vehicle for carrying the detachable sprayer over the field, a cartridge mounted on the frame for holding a quantity of chemicals to be sprayed, a sensor for sensing the speed at which the sprayer is moving over the field, and overall drive structure operatively coupled to the sensor and to the cartridge for varying the output of the cartridge in proportion to the speed at which the sprayer is being moved over the field.

Abstract: A system for selectively containing and dispensing liquids. The system has a container for the liquid with the container including a housing and a flexible diaphragm in the interior of the housing for holding the liquid. An actuator is coupled to the diaphram for moving the diaphragm between an extended position in which the diaphragm can hold more of the liquid and retracted positions in which the diaphragm holds less of the liquid than when in the extended position. A force transmitting unit is coupled to the actuator for causing the actuator to move the diaphragm in a direction from the extended position towards a completely retracted position to dispense the liquid from the container.

Abstract: A self-contained cartridge for transporting and dispensing liquid chemicals. The cartridge includes a hollow body member open at the upper end and divided into a lower closed tank for holding liquid chemicals and an upper open end compartment. A pump is provided to pump liquid chemicals from the closed tank. The pump is activated through a quick disconnect fitting.

Abstract: A direct injection chemical sprayer for spraying a fluid mixture onto a field as the sprayer is moved over the field. The sprayer includes a chemical pump mechanism for pumping chemicals from a chemical tank, a sensing mechanism for sensing the speed at which the sprayer is being moved over the field, and a drive mechanism operatively coupled to the sensing mechanism and to the chemical pump for varying the output of the chemical pump mechanism in proportion to the speed at which the sprayer is being moved over the field. A second embodiment includes self-contained replaceable cartridges each of which has a tank, a pump, drive mechanism therefor, and calibration apparatus. There are removable intermediate gear boxes and a main gear box, each of which has a plurality of selectable drive mechanisms for driving the pump of the gear box at a selected speed.

Abstract: A returnable container system for containing and dispensing liquid chemicals and the like. The system has a drivable reciprocatable pump and a one-way check valve in the suction tube of the system. An attachable assembly unit is provided which includes a rod extension that is reciprocatably driven by a motor and is attachable to the pump rod for the drive of the pump and which includes a counter for indicating the amount of chemicals dispensed from the container. The container system gives the user the option of using the system in a first condition in which the assembly unit is attached or in a second condition in which the assembly unit is detached and the user uses his own separate pump but utilizes the one-way check valve in the suction tube.

Abstract: A pumping system for containing and dispensing liquids, such as poisonous or hazardous chemicals and the like. The system has a spring-biased, manually-openable by pass valve incorporated therein which is selectively positionable in various positions without the user coming in contact with the poisonous or hazardous chemicals and the like.

Abstract: A pump of the diaphragm type. The pump has a replaceable unitary cartridge which fits into a cavity of the pump casing. The casing is in two parts, an upper casing and a lower casing, which are held together by detachable means for replacing the cartridge.

Abstract: A closed pumping system for containing and dispensing liquids such as liquid chemicals and the like. The system has a pump that is an integral part of the container and a driving mechanism for the pump which is detachable from the pump to be used again with subsequent containers. The container with the pump thereon may be disposed of.

Abstract: A pumping apparatus for pumping heavy viscous chemicals and the like. The apparatus has a pump means having means for attachment to a container of the viscous chemicals and the like, and has driving means including a motor and means for detachably connecting the driving means to the pump means so that the pump means and driving means are separable, and the driving means may be used with other pump means.

Abstract: A linkage arrangement which minimizes wear in coupling a hand operated lever to a piston or diaphragm type fuel transfer pump. The arrangement includes U-shaped pin structure which establishes a pair of pivot pins about which may respectfully freely pivot (1) a reciprocating pump action rod, and (2) one end of elongated linkage structure, i.e., as the hand operated lever is operated. Although, relative pivotal movement between the lever and the pair of pivot pins is absolutely impossible even though the pin structure is freely received in aligned apertures provided in the lever, the rod and the linkage structure, thereby substantially eliminating any wear of the lever per se, i.e., particularly adjacent the pivot points thereof and eliminating wear on the pivot pins which would otherwise be caused by relative movement between the parts.
