Patent number: 8939701Abstract: Machines are often used to collect and transport materials in a work environment. One of the more common methods of collecting and transporting materials is with a fork. The tines of a conventional fork may damage the materials being collected by the machine. Tines are also difficult to attach other work implements to. The disclosed apparatus facilitates collecting material with less resultant damage to the material. The disclosed apparatus also simplifies the connection of other work implements to the machine, in particular, a bucket, by not requiring that the fork first be removed from the machine to attach the bucket. The tine has a base member with a distal end; a roller rotatably coupled to the base member proximate to the distal end; and a part of the roller is elevated above the base member.Type: GrantFiled: December 20, 2012Date of Patent: January 27, 2015Assignee: Caterpillar Inc.Inventor: Jimmy L.

Patent number: 7429159Abstract: The end loader bucket attachment includes a bracket attachable to the side plate of an end loader bucket, and an arm pivoting from the bracket. The pivot is oriented generally vertically to allow the arm to swing in a generally horizontal plane, depending upon the tilt of the bucket. When the bucket is tilted somewhat rearwardly, the weight of the arm causes it to swing outwardly to extend generally laterally from the bucket and end loader machine. However, when the bucket is tilted somewhat forwardly, the arm automatically swings forwardly, generally parallel to the longitudinal axis of the machine. The attachment is particularly useful in picking up suspended objects to the side of the bucket and machine, and swinging those loads to a forward position generally in front of the bucket and machine. This greatly reduces the need for maneuvering the machine to pick up and reposition such loads.Type: GrantFiled: February 1, 2006Date of Patent: September 30, 2008Inventors: Joe W. Priest, Robert L. Priest

Patent number: 6493967Abstract: The apparatus for attaching an accessory to an excavator is a device for attaching a grader blade, brush blade, compactor, or other accessory to the bucket of an excavator. The apparatus has a body to which the accessory is attached which has a pair of hooks which slide between adjacent pairs of teeth on an edge of the excavator bucket and a pair of chains attached to the rear of the bucket and tightened by load binders to retain the apparatus on the excavator bucket. The apparatus provides for pivoting the accessory laterally, and may optionally provide for tilting the accessory in a vertical plane.Type: GrantFiled: May 21, 2001Date of Patent: December 17, 2002Inventors: Frederick J. Holmes, David C. Holmes

Patent number: 6481949Abstract: A crane attachment for a front end loader includes arm members pivotally attached to a central portion of a forward end of loader arm. Remote ends of the arms are joined together to form a triangular boom or truss structure. A cable or a chain extends from each arm of the loader to the remote ends of the arm members to support the truss structure. The length of the cable or chain can be adjusted, with a “come-along” or the like, to provide desired leverage and extension of the truss structure. A pulley is attached to the remote ends of the arm members and a winch cable runs through the pulley to permit an object to be lifted with the winch cable. The crane attachment can be used for lifting large objects, in place of a small crane. Also, the crane attachment can be laid back toward the operator cockpit to permit the loader bucket to be used without removing the crane attachment and the bucket need not be removed when using the crane attachment.Type: GrantFiled: July 6, 1999Date of Patent: November 19, 2002Inventor: Michael J. Cullen

Patent number: 6409457Abstract: The invented vehicle includes a chassis, a cabin mounted on a first side of the chassis on a forward portion thereof, and a plurality of wheels coupled to the chassis to movably support the chassis. The vehicle also includes a boom unit, a tool coupled to an end of the boom unit, and turntable unit mounted to the chassis at a central portion thereof, the turntable unit coupled to and supporting the boom unit for rotation relative to the chassis. The turntable unit is capable of moving the boom unit and the tool over a second side of the chassis opposite the first side between a first position at which the tool is positioned forward of the chassis to pick up the load and a second position at which the tool is positioned over the dump body to dump the load into the dump body. The vehicle also includes a dump body mounted to a rear portion of the chassis. The dump body can be tilted to the rear or either side of the vehicle.Type: GrantFiled: October 15, 1999Date of Patent: June 25, 2002Inventors: George Korycan, Libor Belohoubek

Patent number: 6341568Abstract: An expandable stinger planter is described which includes a base frame and a pivot frame mounted to the base frame for pivotal movement thereon about multiple pivot axes. A stinger comprised of a pair of elongated probes is mounted to the pivot frame and extending to bottom ends. A stinger mounting frame is operatively positioned between the pivot frame and at least one of the elongated probes. An actuator on the stinger mounting frame is operable to shift the bottom ends between a closed position and an open wherein the bottom ends are opened and form a plant discharge opening. An internal plant receiving receptacle within the probes is open to the plant discharge opening at the open position whereby a plant placed in the plant receiving receptacle may be discharged through the plant discharge opening.Type: GrantFiled: August 9, 2000Date of Patent: January 29, 2002Inventor: Daniel A. Culley

Patent number: RE43197Abstract: An expandable stinger planter is described for attachment to an excavator type boom. The planter includes a frame arrangement that may be releasably secured to the boom, with a stinger depending therefrom. The boom may be selectively operated to drive the probes deep into the ground. The stinger includes a pair of elongated probes that have bottom ends configured to be opened and closed by operation of an actuator assembly. The actuator assembly is selectively operable to shift the probes relative to one another between a closed position wherein the bottom ends are closed together, and an open position wherein the bottom ends are spaced apart from one another to form a plant discharge opening. The probes form an upwardly open internal plant receiving receptacle that is open to the plant discharge opening at the open position whereby a plant placed in the plant receiving receptacle may be discharged through the plant discharge opening as the probes are lifted by the boom.Type: GrantFiled: December 12, 2002Date of Patent: February 21, 2012Assignee: S & K Holding Company, IncorporatedInventor: Daniel A. Culley
