Publication number: 20240140739Abstract: An offloading vacuum system. The system has a tank to capture debris from an excavation site. The debris is pulled into the tank due to a blower pulling air into an attached hose. An internal conveyor within the tank conveys material to an offloading hub. The offloading hub has a ground-facing door which opens to deposit debris into an external conveyor. The external conveyor, when deployed, can move debris from below the tank to a dump container with a wall greater than a height of the tank.Type: ApplicationFiled: December 29, 2023Publication date: May 2, 2024Inventor: Cody L. Sewell

Publication number: 20240068179Abstract: A trench filling machine having a hopper supported below a tub containing trench filling material. The hopper is configured to deposit the trench filling material into a narrow trench formed in the ground surface. The hopper is attached to a frame of the machine using a suspension system. The suspension system includes a shock absorber configured to raise and lower the hopper in response to shifting of the machine's trajectory. The suspension system further permits limited lateral movement of the hopper in response shifting of the machine's trajectory or variations of the path of the trench.Type: ApplicationFiled: August 24, 2023Publication date: February 29, 2024Inventor: Cody L.

Patent number: 11396734Abstract: A system for uncovering a trench. The system comprises several subsystems, including a work machine and a frame for providing a seal with the surface to be trenched with a saw blade contained therein. The blade is supported on a hub which is slidably movable relative to the frame by operation of a linear actuator, which may be a hydraulic cylinder or the like. The vertical location of the blade within the frame is continuously adjustable to create a deeper or shallower trench. A monitoring system is provided to monitor the vertical location from an operator station.Type: GrantFiled: September 20, 2019Date of Patent: July 26, 2022Assignee: The Charles Machine Works, Inc.Inventors: Cody L.

Patent number: 11185803Abstract: The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.Type: GrantFiled: July 24, 2019Date of Patent: November 30, 2021Assignee: The Charles Machine Works, Inc.Inventors: Cody L.

Patent number: 11015392Abstract: A dual member drill string having a plurality of dual member drill string sections for use in horizontal directional drilling operations. Each drill string section having an outer member and an inner member that is rotatable independently of the outer member. The outer member has a pin end and a box end. The inner member has a pin end disposed within the pin end of the outer member and a box end disposed within the box end of the outer member.Type: GrantFiled: December 13, 2018Date of Patent: May 25, 2021Assignee: The Charles Machine Works, Inc.Inventors: Greg L. Slaughter, Jr., Cody L. Sewell

Patent number: 10745068Abstract: A track assembly is formed from an endless track, an elongate guide member, a drive sprocket, and a plurality of track engaging rollers. The endless track has an inner surface having a plurality of parallel circumferential ridges. Formed between the circumferential ridges is a circumferential channel. The guide member is at least partially positioned and closely received within the circumferential channel. The track engaging rollers are arranged in a pair of parallel rows near an outer side of each circumferential ridge. During track rotation, the guide member remains closely received within the channel, and the rollers contact the outer side of the ridges to resist lateral movement of the track. Positioning of the guide member in the circumferential channel, with the rollers outside the ridges, laterally stabilizes the track thereby reducing the risk of the track slipping off the track assembly.Type: GrantFiled: October 3, 2018Date of Patent: August 18, 2020Assignee: The Charles Machine Works, Inc.Inventors: Cody L. Sewell, Brant Douglas Kukuk

Patent number: 10704227Abstract: A trenching assembly used to cut a narrow trench in the ground surface. The trenching assembly comprises an attachment frame connected to a hood assembly via a linkage assembly. The attachment frame may be attached to the rear end of a work machine. A rotatable blade is disposed within a cavity defined by the hood assembly. The hood assembly may rotate about two different axes relative to the linkage assembly, and the linkage assembly may rotate about two different axes relative to the attachment frame. The trenching assembly uses a pair of accumulators to hydraulically rotate the linkage assembly about a horizontal axis relative to the frame in response changes in depth of the ground surface being cut by the blade. The linkage assembly may be hydraulically rotated using the accumulators without input from the operator.Type: GrantFiled: June 19, 2019Date of Patent: July 7, 2020Assignee: The Charles Machine Works, Inc.Inventor: Cody L.

Patent number: 10655302Abstract: A hydraulic control for an attachment on a work vehicle. The attachment is mounted on the chassis of the work vehicle and movable between a first position and a second position. A hydraulic cylinder is operable to power movement of the attachment. A fluid circuit communicates with the hydraulic cylinder and is configured to carry hydraulic fluid. A fluid reservoir is in communication with the fluid circuit. Accumulators that are in communication with the fluid circuit automatically store and release hydraulic fluid in response to movement of the attachment. A valve assembly controls fluid communication between the fluid reservoir and the fluid circuit in response to movement of the attachment to its second position.Type: GrantFiled: October 31, 2018Date of Patent: May 19, 2020Assignee: The Charles Machine Works, Inc.Inventor: Cody L.

Patent number: 10582652Abstract: A hydraulic control for an attachment on a work vehicle. Power is provided to the attachment by manually actuating a control that is biased toward a first position. This first position corresponds to a deactuated mode of the attachment. By unlocking a lock mechanism, the control may be maintained in a second position under hand pressure. This second position corresponds to an actuated mode of the attachment. The lock mechanism may be actuated by an operator platform-actuated release mechanism. While an operator is on a platform on the vehicle, the lock mechanism remains unlocked, and the attachment maintains its operation without hand pressure on the control. The release mechanism actuates the lock mechanism when an operator is not on the platform. As a result, the attachment is deactuated. A filter may be utilized to prevent premature actuation of the release mechanism.Type: GrantFiled: October 16, 2018Date of Patent: March 10, 2020Assignee: The Charles Machines Works, Inc.Inventors: Brant Douglas Kukuk, Cody L.

Patent number: 10538949Abstract: A vacuum system for use in excavation operations. The system uses a tank having an open end that is closed by a door. The door is opened and closed by a door lifting assembly made up of an upper linkage arm, a lower linkage arm and a hydraulic cylinder. A socket is formed in the upper linkage arm, and a shaft housing is formed in the lower linkage arm. The shaft housing engages with the socket to latch the door closed. The upper linkage arm is attached to the door at a first pivot axis and is attached to the lower linkage arm at a second pivot axis. The lower linkage arm is attached to a side of the tank at a third pivot axis. When the door is open, the second pivot axis extends below a reference plane that contains the first and third pivot axis.Type: GrantFiled: February 19, 2019Date of Patent: January 21, 2020Assignee: The Charles Machine Works, Inc.Inventor: Cody L.
