Hydraulic Latch Pin Assembly For Coupling A Tool To A Construction Equipment

US Patent:
RE37320, Aug 14, 2001
Filed:
Mar 16, 2000
Appl. No.:
9/526973
Inventors:
Lee A. Horton - Jefferson MA
Assignee:
WEC Co. - Hubbardston MA
International Classification:
E02F 396
US Classification:
37468
Abstract:
The invention provides a coupling assembly for coupling a tool to a dipperstick, or arm, on an apparatus which has a hydraulic system for moving the tool. The coupling assembly includes a coupler body having a frame that defines a central cavity, and also having link structure for pivotally coupling to the dipperstick. An actuator assembly positioned within the central cavity includes a latch pin that can slide between an engaged position and a retracted position. In the engaged position, an end of the latch pin projects out from a rear end of the frame for engaging a receptacle defined by the tool. In the retracted position, the end of the latch pin does not project out from the frame. A bias structure normally urges the latch pin toward the engaged position with a bias force. A hydraulic latch cylinder has a fixed part and a movable part rigidly coupled to the latch pin such that, when the movable part is extended from the fixed part, the latch pin is urged to the retracted position.

Hydraulic Latch Pin Assembly For Coupling A Tool To A Construction Equipment

US Patent:
RE37339, Aug 28, 2001
Filed:
Mar 16, 2000
Appl. No.:
9/526972
Inventors:
Lee A. Horton - Jefferson MA
Assignee:
WEC Co. - Hubbardston MA
International Classification:
E02F 396
US Classification:
37468
Abstract:
The invention provides a coupling assembly and method for coupling a tool to a dipperstick, or arm, on an apparatus which has a hydraulic system for moving the tool. The coupling assembly includes a coupler body having link structure for pivotally coupling to the dipperstick. A latch member is movable between an engaged position for engaging the tool and a disengaged position for disengaging from the tool. A spring is arranged to provide a spring force to urge the latch member to the engaged position. A hydraulic motor has a part that is stationary relative to the coupler body and a movable part that can be extended relative to the stationary part when hydraulic pressure is applied to one end of the hydraulic motor. The movable part is coupled to the latch member such that extension of the movable part urges the latch member to the retracted position in opposition to the spring force.

Angled Edge Bucket Excavation Tool

US Patent:
2011012, Jun 2, 2011
Filed:
Dec 2, 2010
Appl. No.:
12/958761
Inventors:
Lee A. Horton - Jefferson MA, US
International Classification:
E02F 3/40
US Classification:
37444
Abstract:
An angled edge bucket excavation tool for excavation use is mounted to an arm of an excavation machine, such as an excavator or loader. The tool has a body mounted for rotation from the arm, a pair of generally flat, non-similar side leading edge plates mounted to the body, a pair of side plates and a formed back sheet mounted to the body and the side leading edges, an angled front leading edge plate mounted to span the region of the angled edge bucket between the side leading edge plates constructed with or without teeth, the angled leading edge attached to the back sheet and the side plates defining, together, an angled edge bucket volume for receiving material excavated from the hard packed substrate during excavation action. Methods of use are also described.

Single Pointed Ripper Bucket Excavation Tool

US Patent:
2008001, Jan 17, 2008
Filed:
Jul 12, 2007
Appl. No.:
11/776966
Inventors:
Lee Horton - Jefferson MA, US
International Classification:
E02F 3/40
US Classification:
037444000
Abstract:
A single pointed ripper bucket excavation tool (SPRB) for use mounted to an arm of an excavation machine has a body mounted for rotation from the arm and a pair of generally flat, side plates mounted to the body and narrowing from a first width in a region of the body to a second, relatively smaller width at a tip region spaced from the body. A single ripper tooth is mounted in the tip region of the ripper bucket. One or more plates are mounted to span a region between the side plates, rearward of the ripper tooth in a direction of ripping motion, to define, with the side plates, a ripper bucket volume for receiving material ripped from the substrate during ripping motion.

Ripper Excavation Tool

US Patent:
7739815, Jun 22, 2010
Filed:
Apr 13, 2007
Appl. No.:
11/735117
Inventors:
Lee A. Horton - Jefferson MA, US
International Classification:
E02F 9/28, E02F 3/96
US Classification:
37452, 37404
Abstract:
A ripper tooth for use mounted on an excavation tool having a tool body mounted for rotation on an excavation machine arm, the ripper tooth being mounted to the tool body for ripping engagement with a substrate. The ripper tooth has first and at least second portions, each with a tip disposed for ripping engagement with the substrate. The first and second portions are laterally spaced apart generally along the axis of rotation of the tool relative to the arm, and the first and second portions are angularly spaced apart generally in a direction of substrate ripping motion. The first portion is disposed on a first axis and the second portion is disposed on a second axis, the first and second axes being different. Ripper excavation tools with one or more ripper teeth of the disclosure mounted to the tool body are also described.

Multi-Shank Ripper

US Patent:
2004014, Aug 5, 2004
Filed:
Jan 22, 2004
Appl. No.:
10/762733
Inventors:
Lee Horton - Jefferson MA, US
International Classification:
E02F003/04, E02F003/64
US Classification:
037/411000
Abstract:
An excavating tool for pivotal attachment about an axis to the outboard end of the dipperstick of an excavating system, the tool having multiple shanks offset longitudinally of the axis and offset radially about the axis.

Multi-Shank Ripper

US Patent:
7322133, Jan 29, 2008
Filed:
Aug 29, 2005
Appl. No.:
11/214607
Inventors:
Lee A. Horton - Jefferson MA, US
International Classification:
E02F 3/96
US Classification:
37404
Abstract:
A multi-shank ripper excavation tool has a body mounted from an arm, e. g. a dipper arm or a boom arm, and at least first and second shanks mounted to the body. Each shank is perpendicular to an axis of rotation of the tool, and each the shank includes a ripper tooth positioned for ripping engagement with a substrate. The shanks and ripper teeth are laterally spaced apart along the axis of rotation relative to the arm, and the ripper teeth are angularly spaced apart in a direction of substrate ripping motion. In some implementations, plates are mounted to span a region between two or more shanks, rearward of the teeth in a direction of ripping motion, and define, with the shanks, a bucket volume for receiving material ripped from the substrate. Methods for ripping excavation of a substrate employing the above excavation tools mounted on a dipper stick or a boom arm are also described.
