Patent number: 4793742Abstract: A truck mounted particulate material applicator which entrains metered amounts of the particles in a fluid for conveying the material outwardly along tubes forming boom assemblies. The metering assembly and the booms are mounted in the mid portion of the truck wheel base for minimizing bouncing, and excess shock loads on the booms during travel, and also for providing a centrally located distribution point for the metering assembly. The present device includes a unique manifold for entraining particulate materials such as inorganic fertilizer or grains in fluid flow streams within tubes in which they form the boom assemblies. Each tube carries the metered air entrained material a different distance from the center to cover a wide path. Separate tubes are directed toward the rear of the truck to spread the material in the path of the truck.Type: GrantFiled: October 5, 1987Date of Patent: December 27, 1988Assignee: TCI, Inc.Inventor: Glen L. Strand

Patent number: 4790484Abstract: Spreading apparatus for attachment to a vehicle for distributing granular materials such as fertilizer and the like, using air as the distributing medium. The spreading apparatus includes a rear-mounted boom and an air system in which the material distribution passageways are substantially straight from the discharge of the fans to the point of material introduction to the discharge nozzles along the boom. This is achieved by the use of two blowers that move air in opposite directions through a cross-over tube array into which the already-divided material is introduced into individual air passageways leading to the discharge nozzles mounted along the boom. The boom itself is designed so that it can be quickly and easily folded and pivoted for storage or transport.Type: GrantFiled: October 22, 1986Date of Patent: December 13, 1988Assignee: Highway Equipment CompanyInventor: George B. Wall

Patent number: 4767062Abstract: An air fertilizer spreader mounted on a truck chassis, the truck chassis carrying a granular or pulverized fertilizer application machine. Right and left booms swing from a midship position between a truck cab and fertilizer box back towards the rear of the truck chassis. Each boom includes a plurality of boom tubes with deflectors. Rear boom tubes are also provided at the rear of the truck chassis. A screw conveyor carries fertilizer from the fertilizer transport box to an area forward of the fertilizer transport box where the fertilizer falls into opposing metering assemblies for the right and left boom. Air, acting through particle accelerators carries the fertilizer from the metering assembly to the entrance of the boom tubes, and a second particle accelerator provides additional air flow to carry the fertilizer down the length of each of the boom tubes to the point of discharge.Type: GrantFiled: February 17, 1987Date of Patent: August 30, 1988Assignee: Grant FletcherInventor: Grant Fletcher

Patent number: 4591102Abstract: Apparatus for spreading chaff includes brackets for mounting the apparatus beneath and rearwardly of the cleaning shoe of a combine or other grain threshing machine and separately of any straw chopping and spreading apparatus provided adjacent the straw discharge opening. The apparatus comprises a pair of fans rotatable in a horizontal plane above a base plate and upstanding walls defining housings around the fans and discharge nozzles extending to the sides of the apparatus to discharge the chaff from each fan in a sideward direction and to substantially prevent discharge of chaff rearwardly of the apparatus.Type: GrantFiled: August 20, 1984Date of Patent: May 27, 1986Inventor: James A. Clarke

Patent number: 4569486Abstract: A pneumatic distributing device which can be used for broadcasting particulate fertilizer, herbicide or the like includes a tank, a slot across the tank with a metering roller in the slot for metering the particulate material into a number of receptacles arranged along the slot. A first venturi at the bottom of the receptacle transports the material in the receptacle through a first portion of the duct to a junction provided by a second venturi and a second duct. The second duct extends outwardly along a boom with a number of such ducts arranged in a vertically stacked arrangement which is selfsupporting. The second ducts incline slightly downwardly and are straight from the feed end to an open mouth at the outer end. A deflector attached to the open mouth has a first and then a second surface for spreading and then deflecting the material from the open mouth to the ground with the spread taking place along the length of the boom.Type: GrantFiled: January 30, 1984Date of Patent: February 11, 1986Inventor: Charles Balmer

Patent number: 4562968Abstract: A pneumatic spreader for the distribution of materials and a flow distributor for same are disclosed. The spreader includes a distribution chamber having multiple compartments with a gas inlet and material outlet defining a venturi in each of the compartments. The materials are discharged from the distribution chamber and its compartments through first conduits coupled to the respective material outlets and a plurality of second conduits communicating with each of the first conduits for receiving the materials and discharging them to the ground. A flow distributor adjacent the juncture of the first and second conduits equally divides the materials in the first conduit between the second conduits. The flow distributor includes a substantially circular plate having a plurality of openings which communicate to the second conduits and a substantially conical deflector which is adjustable both linearly and is eccentrically rotatable for adjusting the flow between the plate openings.Type: GrantFiled: March 19, 1984Date of Patent: January 7, 1986Assignee: Dry Sprayer, Inc.Inventors: Gerald L. Widmer, Larry J. Gray

Patent number: 4489892Abstract: An apparatus (10) for distributing a substance (18) from a container (16) among a plurality of delivery channels (22) is disclosed. Apparatus (10) includes an auger (20) for moving a stream of substance (18) upwardly for outward centrifugal deflection by paddles (44) into a plurality of distributor pockets (60). Substance (18) which impacts and is retained in distributor pocket areas falls gravitationally into delivery tubes (22) for subsequent movement by pressurized air to outputs (26).Type: GrantFiled: March 20, 1984Date of Patent: December 25, 1984Assignee: Lor-Al CorporationInventor: Loren E.

Patent number: 4432675Abstract: The invention relates to improvements in air seeders, namely agricultural implements which utilize air pressure to move particulate material such as seeds from a feed zone to a dispersal or planting zone. The particulate material is normally fed from a hopper by a driven feed wheel or other similar mechanism. The invention provides a pressure pick-up at the source of air pressure, a conduit connecting the pick-up with a pneumatic actuator and a suitable linkage connecting the actuator with a clutch which is used to transmit drive power to the feed wheel. As long as there is sufficient pressure at the source the actuator will keep the clutch positioned to permit the feed wheel to operate. Should the pressure source fail the actuator will operate the clutch to stop transmitting power to the feed wheel and thus terminate the feeding of material which would otherwise clog the delivery conduits of the seeder.Type: GrantFiled: May 3, 1982Date of Patent: February 21, 1984Assignee: Morris Rod-Weeder Co.
