Publication number: 20190133020Abstract: A towed vehicle hitch tongue includes movably connected front and rear tongue members, and a fully exposed master cylinder connected at opposite ends thereof to the tongue members such that a rearward force urging the front tongue member toward the rear tongue member forces pressurized braking fluid out of a port thereof into a braking circuit configured to exert a braking force. The braking circuit prevents braking until the rearward force warrants braking, provides dampening of the brake action, allows the towed vehicle to reverse, and can provide emergency stopping and dampening of movement of the hitch tongue. Instead of using movable front and rear tongue members, sensors can detect what the towed vehicle is doing, and apply appropriate braking force in response.Type: ApplicationFiled: January 3, 2019Publication date: May 9, 2019Inventors: Scott Gerbrandt, Scot Jagow

Patent number: 10251334Abstract: A parallel arm furrow opener assembly defines upper and lower front pivot axes and upper and lower rear pivot axes oriented horizontally and perpendicular to a travel direction. A furrow opener and a packer wheel are attached to a rear link of the assembly. In operation the furrow opener and the packer wheel are in fixed positions with respect to the rear link member, and a bias element is operative to exert a downward bias force on the furrow opener assembly. A front pivot line connecting the upper and lower front pivot axes is parallel to a rear pivot line connecting the upper and lower rear pivot axes, and the front and rear pivot lines are oriented at a pivot angle with respect to a vertical orientation, and the pivot angle is adjustable to vary a furrow depth of the furrow.Type: GrantFiled: September 18, 2017Date of Patent: April 9, 2019Assignee: Bourgault Industries Ltd.Inventor: Scot Jagow

Publication number: 20190082587Abstract: A seeding apparatus has a frame and a plurality of furrow openers spaced laterally along the implement frame. A like plurality of singulating meters is provided, each mounted on the frame close to a corresponding furrow opener, and seed tubes are configured to receive singulated seeds from a corresponding singulating meter and deposit the seeds in the furrow created by the corresponding furrow opener. A pressurized air stream conveys seeds through each seed tube and a seed supply supplies seeds to each singulating meter. A meter control operates each singulating meter to provide a variable seeding rate that is independent of the seeding rates of the other singulating meters. A seed catching member follows each furrow opener and catches the seeds exiting the seed tubes to maintain a consistent seed spacing in the furrow.Type: ApplicationFiled: November 19, 2018Publication date: March 21, 2019Inventors: Scot Jagow, David Corriveau, Robert Klenz, Scott Gerbrandt

Patent number: 10149427Abstract: An air seeder distribution apparatus has a manifold and a plurality of delivery conduit connected to ports of the manifold. A supply conduit carries a product air stream and is connected the manifold interior. A port valve when open connects a delivery conduit to the manifold interior through the port and disconnects same when closed. A purging conduit connects the supply conduit, at a clean air location configured to receive from the supply conduit a clean air stream with no agricultural products entrained therein, to the delivery conduit such that the clean air stream has an open path from the supply conduit to the delivery conduit. When the port valve is open the clean air stream flows through the purging conduit at a low first flow rate, and when the port valve is closed the clean air stream flows through the purging conduit at a second significantly greater flow rate.Type: GrantFiled: February 24, 2017Date of Patent: December 11, 2018Assignee: Bourgault Industries Ltd.Inventors: Gerard Bourgault, Mark Cresswell, Scot Jagow

Patent number: 9930823Abstract: A system for reducing implement wheel forces on a field surface has an agricultural implement with a frame mounted on frame wheels and ground engaging tools mounted on the frame. When the ground engaging tools move down to penetrate the field surface they exert an upward tool force on the frame. Support arms are movably connected to the implement frame and a support wheel is rotatably mounted to each support arm. A support bias element exerts a support bias force on each support arm to force the support wheel against the field surface and to correspondingly force the implement frame upward, transferring a supported frame weight from the implement frame to the support wheels, such that an unsupported frame weight is carried on the frame wheels. A bias control varies the support bias forces to maintain the unsupported frame weight at a level greater than the upward tool force.Type: GrantFiled: November 21, 2014Date of Patent: April 3, 2018Assignee: Bourgault Industries Ltd.Inventors: Scot Jagow, Robert Klenz, Aden Arguin

The apparatus also includes a delivery conduit connected to each one of the plurality of ports. On at least one of the plurality of ports, a port valve configured to communicate an interior of the manifold body with the delivery conduit associated with the at least one of the plurality of ports. The apparatus also includes a supply conduit connected at an output end thereof to the interior of the manifold body and connected at an input end thereof to receive a product air stream with agricultural products entrained therein. The apparatus also includes an exhaust orifice defined in the supply conduit and an exhaust valve configured to control a flow of pressurized air from an interior of the supply conduit through the exhaust orifice.Type: ApplicationFiled: September 20, 2017Publication date: March 22, 2018Inventors: Haydon Rice, Scot Jagow

Patent number: 9699953Abstract: An air seeder apparatus has a frame and a plurality of furrow opener assemblies spaced across a width of the frame at a narrow row spacing, and a plurality of bulk product containers and a bulk meter mounted on each, one of which dispenses seeds through a distribution network to a seed tube on each furrow opener assembly. A plurality of singulating meter is provided, each dispensing singulated seeds to the furrow opener on one of the furrow opener assemblies. During singulating operation seeds are delivered to the singulating furrow opener assemblies only by the singulating seed meter, and during conventional operation seeds are delivered to the singulating furrow opener assemblies only by the bulk meter. A lift system, when in a singulating mode, maintains idle conventional furrow opener assemblies in the transport position while moving singulating furrow opener assemblies between the operating position and the transport position.Type: GrantFiled: January 13, 2016Date of Patent: July 11, 2017Assignee: Bourgault Industries Ltd.Inventors: Scot Jagow, Mark Cresswell

Patent number: 9295191Abstract: An air distribution apparatus has a manifold body, and ports defined through walls thereof, with a delivery conduit connected to each port. A port valve is configured to connect and disconnect the delivery conduit to the interior of the manifold body. A supply conduit delivers a product air stream with agricultural products entrained therein to the interior of the manifold body. The supply conduit extends vertically up from the manifold to a curved elbow and then extends horizontally from the elbow. An exhaust orifice is defined in the inner radius of the elbow. When an exhaust valve is open, a selected flow of pressurized air flows from the supply conduit through the exhaust orifice. The port valve and exhaust valve are controlled such that when the port valve closes, the exhaust valve opens. The exhaust air can be directed into the delivery conduits to clear product therefrom.Type: GrantFiled: February 13, 2014Date of Patent: March 29, 2016Assignee: Bourgault Industries Ltd.Inventors: Scot Jagow, Haydon Rice, Bob Cochran, Bryan Cresswell

Patent number: 9271439Abstract: An air seeder includes a combination tank propulsion vehicle with mounted product tanks, and metering devices dispensing product from each product tank. A furrow opener implement is towed by the vehicle and an engine rotates the vehicle wheels and two or more implement wheels. A pneumatic distribution system conveys dispensed products to the furrow openers. The external guidance system sends location signals indicating a location of the implement frame to the operator. Steering, metering, and distribution signals are sent by both the external guidance system and an operator with a remote operator control, and operator signals override signals from the external guidance system.Type: GrantFiled: January 24, 2014Date of Patent: March 1, 2016Assignee: Bourgault Industries Ltd.Inventors: Gerard Bourgault, Mark Cresswell, Bob Cochran, Scot Jagow
