  • Patent number: 11589498
    Abstract: A planter system for planting seeds and dispensing a fluid includes a seeder assembly including a seed meter configured to dispense a group of seeds through a seed tube, a nozzle assembly configured to dispense the fluid in response to receiving a control signal, and a sensor configured to transmit detection signals upon detection of the first and last seeds passing through the seed tube. The planter system further includes a control system communicatively coupled to the sensor to receive the detection signals from the sensor and identify a trigger time based on the detection time of the first seed, the detection time of the last seed, or a time between the detection times. The control system transmits the control signal to the nozzle assembly based on a number of seeds in the group and the trigger time to apply the fluid on or adjacent the group of seeds.

    Abstract: A traveled path marker on a riding vehicle marks a path that the vehicle has traveled with dry particles or liquid from a holder on the vehicle. The marking material flows from a nozzle located near a bottom of the vehicle, or is delivered to a tire which transfers the marking material to the pavement. The path marking alerts following vehicles to an ahead slower moving vehicle or to the paths regularly traveled by slower moving vehicles and encourages similar vehicles to follow those paths. The marked paths also alert pedestrians to shared paths or when crossing bicycle paths.

  • Patent number: 4436230
    Abstract: A device for providing pulsation-free feeding of a liquid medium from a supply container to a consuming device for use in a road-marking machine is disclosed. Two statically-operating reciprocating-piston pumps are arranged between the supply container and the consuming device such that when one pump is on suction stroke, the other is on a feed stroke. The pump flow rate is proportional to the drive speed of the road-marking machine and the feed flow of each pump has zones which overlap the other. The feed sides of the pumps are connected to a change-over means which alternately connects delivery flows from the pumps to the consuming device and also connects the pressure side of the pumps simultaneously to the consuming device and to the supply container, which prevents pressure flow fluctuations as the back-pressure to each pump is the same.

  • Patent number: 4322034
    Abstract: A hydraulic rate control system for maintaining a selected application rate at varying ground speeds. The application rate is selected through an operator control which permits the operator to dial in the spray tip size, the width of the spray pattern per tip and the desired spray rate in gallons per acre, and this application rate can be changed on the go. A ground-driven hydraulic oil pump directs its entire flow through a variable orifice, adjusted through manipulation of the operator control, and the oil pressure acts against a balance valve which maintains the pressure of the chemical to be sprayed equal to the oil pressure at the variable orifice. As the ground speed increases or decreases, the oil pressure and thus the chemical pressure increases or decreases accordingly to maintain the selected application rate.

  • Patent number: 4027788
    Abstract: A lawn spreader includes an elongated generally rectangular hopper supported by a set of wheels and having a bottom member formed by a longitudinally extending aluminum extrusion. The extrusion has upwardly projecting inclined flange portions which are secured to the inclined side walls of the hopper, and the flange portions are integrally connected by a lower portion defining a longitudinally extending guideway. A slide member is supported within the guideway and is also formed from an aluminum extrusion. The slide member includes a longitudinally extending integral rib which projects downwardly and connects directly with the lower end portion of a control lever pivotally supported by a side wall of the hopper. The upper end portion of the lever engages a rotatably adjustable cam for precisely positioning the slide member to regulate accurately the discharge of material from the hopper through a set of spaced apertures within the extrusions.
