Patent number: 6926217Abstract: A heavy-duty demolition shear for attachment to the boom structure and hydraulic system of an excavator, has a rigid lower jaw and an upper jaw and pivot interconnecting the jaws together. The shear is attachable to the boom structure of the excavator. The upper jaw has upper shear blades, while the lower jaw has at least one lower shear blade. The lower jaw also has a rigid guide blade lying along the lower shear blade and in spaced relation therewith. The outer ends of the shear blade and guide blade are co-extensively opposed to each other so that a tie plate secures the outer ends of the lower shear blade and the guide blade together. There is an open slot between the lower shear blade and the adjacent guide blade to receive the upper shear blade and upper jaw therein. The upper jaw has a cylinder attached to the hydraulic system of the excavator for closing and opening the upper jaw relative to the lower jaw.Type: GrantFiled: March 14, 2000Date of Patent: August 9, 2005Assignee: Genesis Attachments, LLCInventors: Kenneth R. LaBounty, Ross D. Christenson, Daniel P. Jacobson

Patent number: 6438874Abstract: A hydraulic rotary grinder for attachment to construction machinery such as an excavator, consisting of a rotating drum having a hollow core and a plurality of attached replaceable grinding tips. A hydraulic motor rotates the drum, and is secured within the hollow core and activated by the hydraulic system of the construction machinery. A planetary gearbox is associated with the hydraulic motor to provide speed changes. At least one weight within the hollow core provides shock absorption and additional mass to the rotating drum. A heat-absorbing liquid within the hollow core absorbs heat from the grinding operation and a seal prevents the heat-absorbing liquid from leaking out of the drum. A number of water nozzles may be mounted on the apparatus for dust suppression. A second hydraulic motor may be provided for increased torque and grinding capacity.Type: GrantFiled: September 8, 2000Date of Patent: August 27, 2002Assignee: Genesis Equipment and Manufacturing, Inc.Inventors: Kenneth R. LaBounty, Ross D. Christenson, Daniel P. Jacobson

Patent number: 6119970Abstract: A heavy-duty shearing and crushing demolition apparatus for attachment to a boom structure and hydraulic system of an excavator. The apparatus includes a lower jaw with a primary blade, an upper jaw with primary and secondary blades oblique with respect to each other, and a shearing and crushing tip on the upper jaw secondary blade with a shearing point, a crushing point, and a support and shearing tip blade portion between the shearing point and the crushing points. This structure exposes the crushing point for crushing when the upper jaw is open from the lower jaw with the shearing tip out of the way and also exposes the shearing tip for shearing when the upper jaw is closing into the lower jaw. This permits shearing beginning at the shearing tip and shearing rearwardly. The support and shearing tip blade portion supports the workpiece while shearing it, producing a substantially flat non-contoured or twisted workpiece.Type: GrantFiled: March 12, 1999Date of Patent: September 19, 2000Assignee: Genesis Equipment & Manufacturing, Inc.Inventors: Kenneth R. LaBounty, Ross D. Christenson, Daniel P. Jacobson

Patent number: 6061911Abstract: A blade stabilizer device for a heavy-duty material handling demolition tool for shearing and crushing scrap material which includes a lower jaw connected to the boom structure of a hydraulic system of an excavator and has an upper jaw pivotally connected and closeable upon the lower jaw at a pivot point. The blade stabilizing device consists of a wear guide pad supported by the lower jaw adjacent the pivot point slidably engaging the upper movable jaw to keep the upper jaw in close engagement with the lower jaw. The wear guide pad is mounted behind the pivot point. A second wear guide pad may be mounted in front of the pivot point on the opposite side of the upper jaw to cross-brace the upper jaw.Type: GrantFiled: November 25, 1998Date of Patent: May 16, 2000Assignee: Genesis Equipment and Manufacturing Co.Inventors: Kenneth R. LaBounty, Ross D. Christenson, Daniel P. Jacobson

Patent number: 5060378Abstract: A demolition tool for attachment to the boom structure and hydraulic system of a hydraulic excavator having a pair of jaws pivotally connected together as to be mountable on the frame of the tool by a movable pin so that the jaws may be placed with other jaws having other forms of demolition characteristics. The jaws may be a shear for steel or other structural material, including concrete, and the jaws may be a concrete crusher, a rock or coral breaker, a wood shear, a plate shear, or other form of demolition device. Both jaws are swingable and independently swingable, operated by a common manifold supplying hydraulic fluid to the cylinders. The jaws swing through operational arcs and are arranged so that the direction of thrust from the cylinders is tangential to the pin connecting the cylinders to the jaws at a location intermediate the ends of the operational arcs.Type: GrantFiled: December 15, 1989Date of Patent: October 29, 1991Assignee: LaBounty Manufacturing, Inc.Inventors: Roy E. LaBounty, Kenneth R. LaBounty

Patent number: 5044569Abstract: An attachment for a hydraulic excavator including a pair of jaws mounted on a frame and having offset points or projections on the jaws to apply localized pressure onto a rock or coral piece for breaking the workpiece. Both jaws are movable and operable by individual hydraulic cylinders. The direction of thrust against the jaws being tangential to the arc of movement of the pins for connecting the cylinders to the jaws at a location approximately midway of the operational arc of the jaws.Type: GrantFiled: December 15, 1989Date of Patent: September 3, 1991Inventors: Roy E. LaBounty, Kenneth R. LaBounty

Patent number: 4907356Abstract: The present scooper of slipper bucket is attachable to an upper jaw of a grapple connected to the boom structure of a hydraulic excavator. The scooper bucket includes a bucket like rigid enclosure forming a tine receiving opening for receiving a tined jaw of the grapple. The tines of the grapple slide into or are inserted through the opening. Distal tip ends of the tines slide into the holding sockets formed inside the bucket enclosure. A pair of removable hooks affixed to the proximal inner ends of the tines are secured to a shaft mounted to the bucket like enclosure over the tine receiving opening. The scooper bucket is readily connected to the upper jaw and operates to scoop up and remove gravel, dirt or sand.Type: GrantFiled: January 23, 1989Date of Patent: March 13, 1990Inventor: Kenneth R. Labounty

Patent number: 4719975Abstract: A rotating hammer-shear for releasable attachment to the boom structure and hydraulic system of a hydraulic excavator for the demolition of concrete structures. The hammer-shear having a heavy duty power operated shear and hammer secured to and extending from opposite ends of a common frame. The frame includes a rotational mounting. The rotational mounting provides for rotation of the hammer-shear through an arc of 360.degree. about an axis essentially perpendicular to the line of longitudinal extension of the shear and hammer from the frame. The rotational mounting also provides for pivotal attachment of the hammer-shear to the boom structure and hydraulic system of the excavator.Type: GrantFiled: February 28, 1986Date of Patent: January 19, 1988Inventor: Kenneth R.

Patent number: 4720032Abstract: A rail segmenting machine for releasable attachment to the boom structure and hydraulic system of a hydraulic excavator. The present invention includes a frame consisting of rigid spaced apart plates that generally define a top end, an inlet end, a bottom end, an outlet end and an interior cavity. The top end of the frame is releasably secured to the boom structure and hydraulic system of the excavator and includes mounting ears extending outwardly therefrom adjacent the inlet end for swingable mounting of a hydraulically operated grapple thereto. A hydraulically operated notching arm is pivotally secured within the cavity of the frame and cooperates with an anvil secured to the bottom portion of the frame for producing a notch in a railroad rail extending therebetween. A hydraulically operated breaking head is mounted adjacent the outlet end of the frame and moves in a direction perpendicular to the extension of the rail exterior of the outlet end of the frame.Type: GrantFiled: August 12, 1986Date of Patent: January 19, 1988Inventor: Kenneth R.
