Patent number: 10471435Abstract: Shredder hammers having first and second major surfaces on opposing sides, and a circumferential edge. A mounting portion includes a mounting hole that extends from the first major surface to the second major surface, and is configured to receive a hammer mounting pin for mounting in a reducing system. The circumferential edge includes a primary impact face to initially impact materials to be reduced and a wear edge to subsequently crush and shear the material against a wall of the equipment. The hammer is biased forward on the pin to admit more material to be crushed between the wear edge and the grates.Type: GrantFiled: November 28, 2017Date of Patent: November 12, 2019Assignee: ESCO GROUP LLCInventors: David M. Graf, Michael R. Weeks, John P. Hoice, Daniel R. Morrow, Terry L. Briscoe, Christopher M. Carpenter

Patent number: 10113293Abstract: A bucket for use with a cable shovel includes a shell and a door collectively defining a cavity for gathering material to be excavated. The door is pivotally secured about a pivot axis on the shell so that the door can pivot between a closed position for gathering the material and an open position for dumping the material. The pivot axis is positioned forward of an exterior surface of a back wall of the shell to create a shallower and less forceful door swing during dumping. The door has a front portion that is bent towards a digging edge on the shell so that the door has greater strength, improves bucket loading, and moves a portion of the shell away from the highest wear area.Type: GrantFiled: August 29, 2013Date of Patent: October 30, 2018Assignee: ESCO Group LLCInventors: Terry L. Briscoe, Charles G. Ollinger, IV, Joshua L. Strom

Patent number: 9512600Abstract: Coupling assemblies for releasably holding separable parts together, and in particular for releasably securing a wear member to a support structure in excavating equipment are formed so as to provide increased take up to ensure a tight fit of the wear member on the support structure even if considerable deviation between the parts exists due to wearing, manufacturing variations or the like. The coupling assemblies are suitable for securing points, adapters, shrouds, or other replaceable component to various excavating equipment. The components of the coupling assembly include a wedge and a spool that pivots about a fulcrum when the wedge is driven into assembly for increased take up capabilities. The spool is rotatably engaged around a fulcrum of the support structure and has a bearing portion that bears against and moves the wear member to be secured to thereby take up any gaps between the engaging surfaces of these members.Type: GrantFiled: March 26, 2014Date of Patent: December 6, 2016Assignee: ESCO CORPORATIONInventors: Terry L. Briscoe, Kevin S. Stangeland

Patent number: 8756907Abstract: A coupling link for connecting two parts together includes link components (which each form a partial link) that are joined together with a removable support. The support and link components are coupled together to withstand high loads and/or adverse wear conditions. The inventive construction is strong, durable, efficient, cost effective and easy to use. Wear caps are provided to facilitate extended usable chain life.Type: GrantFiled: August 29, 2012Date of Patent: June 24, 2014Assignee: ESCO CorporationInventors: Terry L. Briscoe, Christopher M.

Patent number: 8312650Abstract: In a wear assembly for securing wear members to excavating equipment, a spool is used with a wedge to hold the wear member in place. The spool is formed with at least one laterally extending arm at its upper end in lieu of an axial arm such as used in a conventional C-shaped spool. In this way, the spool can be easily supported in the assembly as the wedge is installed. The spool does not fall through the opening and no special care is needed to prevent it from falling. The spool also holds itself in place when the wedge is driven into the passage. As a result, installation of the wear assembly is easier and less hazardous. In addition, the lateral support reduces the risk that the spool will suffer spreading.Type: GrantFiled: June 30, 2011Date of Patent: November 20, 2012Assignee: ESCO CorporationInventors: Robert McClanahan, Terry L. Briscoe

Patent number: 8308094Abstract: Shredder hammers include a hammer pin opening in which at least some portion of the interior surface is curved in a direction moving from one major surface of the shredder hammer to the other. This interior surface may be smoothly formed as an arc of a circle, as a parabola, as a hyperbola, or as another curved surface, with the local extrema within the interior of the hole (e.g., at or near the center). Providing the curved interior surface helps vary and disperse the locations where force is absorbed due to contact between the hammer pin and the walls defining the hammer pin opening when the shredding hammer blade contacts the material to be shredded. Other structures include engagement between the hammer pin and the hammer as part of a bushing member, a spool or sleeve member, or a ball swivel member.Type: GrantFiled: February 26, 2010Date of Patent: November 13, 2012Assignee: ESCO Corp.Inventors: John P. Hoice, Lonny V. Morgan, Daniel R. Morrow, David M. Graf, Terry L. Briscoe

Patent number: 8104200Abstract: A lock that includes a wedge that is used to releasably secure separable components of an assembly together. The wedge can be used with a spool. The wedge and spool are threadedly coupled together to drive the wedge into and out of an opening in the assembly without hammering or prying. The direct coupling of the wedge and spool eliminates the need for bolts, washers, nuts and other hardware so as to minimize the number of parts. As a result, the lock is inexpensive to make, easy to use, and unlikely to become inoperative because of lost or broken parts or due to fines or other difficulties encountered in harsh digging environments. Further, the wedge can be driven into the assembly to provide the degree of tightness necessary for the intended operation and/or to re-tighten the assembly after incurring wear during use. A latch assembly is preferably provided to securely hold the wedge in place and avoid an undesired loss of parts during use.Type: GrantFiled: October 13, 2010Date of Patent: January 31, 2012Assignee: ESCO CorporationInventor: Terry L Briscoe
