Patent number: 7753641Abstract: A latch is capable of automatically latching and unlatching an implement, such as a thumb used on the stick of a hydraulic excavator. The thumb may be moved to a stored, inactive position by the operator and automatically latched, or locked, in that position by the latch. To automatically engage the latch, and latch the thumb in its stored position, the operator moves the thumb to its stored position under the force of the thumb actuator. To automatically disengage the latch, and unlatch the thumb, the operator moves the thumb out of its stored position. The force of the thumb on the latch will overcome the latch's unlatching force. But unintentional drifting of the thumb will not cause a force great enough on the latch to overcome the unlatching force and disengage the latch. Also, the latch can be easily manually disengaged by a technician.Type: GrantFiled: April 13, 2006Date of Patent: July 13, 2010Assignee: Caterpillar IncInventor: Gregory A. Seljestad

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: 6988866Abstract: A fork lift attachment for multi-purpose buckets that is easily installed and secured. The mechanism fits under the bucket and is supported by a slot on the top side of the tine and a latch at the heel of the tine. The latch is tightened causing the fork lift attachment to be cinched onto the bucket. A security chain readily and visibly secures the latch so as to prevent the fork lift attachments from being dislodged even if the hydraulics open the bucket.Type: GrantFiled: June 4, 2003Date of Patent: January 24, 2006Assignee: Construction Technology, Inc.Inventors: Kenneth R.

Patent number: 6932556Abstract: A slab tipping apparatus for tipping slabs onto forks of a forklift. The slab tipping apparatus includes a base member being designed for being selectively coupled to a carriage of the forklift. A pivoting assembly is coupled to the base member. The pivoting assembly is designed for being selectively to the carriage of the forklift whereby the pivoting assembly extends between the base member and the carriage of the forklift. The pivoting assembly is designed for being actuated by a user for pivoting the base member with respect to the carriage of the forklift. An arm member slidably engages the base member whereby the arm member is selectively extendable from the base member. The arm member is designed for engaging an edge of the slab whereby the arm member tips the slab onto the forks of the forklift when the pivoting assembly pivots the base member.Type: GrantFiled: January 17, 2003Date of Patent: August 23, 2005Inventor: Jeffrey M. Ecker

Patent number: 6886279Abstract: A loader coupler includes first and second dump stops located on opposite lateral sides of the coupler and first and second roll-back stops located on opposite lateral sides of the coupler. Each of the dump and roll-back stops includes a base connected to or formed as a part of the coupler; at least one shim located adjacent the base; and, a cover releasably connected to the base and located adjacent the at least one shim. Accordingly, the at least one shim is located between the cover and the base. The outer face of the cover can be angled to ensure flush contact between it and an associated arm of a loader to which the coupler is connected. The adjustable stops are used by locating at least one shim adjacent the base and securing the a cover to the base member and adjacent the shim, with the shim located between the cover and the base member. Thereafter, it is determined if the cover contacts the associated loader arm in a desired stop position.Type: GrantFiled: October 23, 2001Date of Patent: May 3, 2005Assignee: JRB Company, Inc.Inventor: Allen E.
