Patent number: 10422222Abstract: A tool includes an actuator assembly, a rod, a first nut, and a second nut. The actuator assembly includes a cylinder, a ram, and a bore extending through the cylinder and the ram. The cylinder includes an internal chamber supporting the ram, a first end, a second end, and a reaction surface positioned proximate the first end. The ram is movable relative to the cylinder and positioned adjacent the second end of the cylinder. The rod extends through the bore of the actuator assembly. The first nut is selectively coupled to one of a first end of the rod and a second end of the rod, and defines a first dimension larger than the bore width of the bit block. The second nut is selectively coupled to the other of the first end of the rod and the second end of the rod, and defines a second dimension less than the bore width.Type: GrantFiled: June 11, 2018Date of Patent: September 24, 2019Assignee: Joy Global Underground Mining LLCInventors: Michael L. O'Neill, Randy W. Arnold

Patent number: 10053983Abstract: A cutting bit assembly includes a block, a bit sleeve, and a seal. The block includes a first bore and a fluid passage. The fluid passage includes a first portion and a second portion in fluid communication with the first portion. The first portion is oriented obliquely with respect to the first bore, and the second portion extends at least partially around the perimeter of the first bore. The bit sleeve includes a shank, a flange, and a second bore extending through the shank and the flange. The shank is positioned within the first bore of the block such that a surface of the flange engages a first end surface of the block. The seal is positioned between the second portion of the fluid passage and the shank to prevent contact between a fluid in the fluid passage and the outer surface of the shank.Type: GrantFiled: September 18, 2017Date of Patent: August 21, 2018Assignee: Joy Global Underground Mining LLCInventors: Randy W.

The fluid passage includes a first portion and a second portion in fluid communication with the first portion. The first portion is oriented obliquely with respect to the first bore, and the second portion extends at least partially around the perimeter of the first bore. The bit sleeve includes a shank, a flange, and a second bore extending through the shank and the flange. The shank is positioned within the first bore of the block such that a surface of the flange engages a first end surface of the block. The seal is positioned between the second portion of the fluid passage and the shank to prevent contact between a fluid in the fluid passage and the outer surface of the shank.Type: ApplicationFiled: September 18, 2017Publication date: January 4, 2018Inventors: Randy W.

Patent number: 9415939Abstract: A chain driven by two sprockets spaced a short distance apart along their common axial centerline. The chain includes elongated pins that extend beyond the outer surfaces of the chain link plates, on both sides, by a distance about equal to the width of the spaced apart sprockets. The chain is aligned midway between the sprockets, and the sprocket teeth drive on the extended portion of the chain pins. Where a flight is attached to the chain links, the pins are extended still further, to fit into the indentations or holes in the flights. This provides an exposed length of each pin in alignment with the sprocket on each side for driving purposes. The chain has a piece extending between the plates to reduce the likelihood of a pin extending further outside of one side plate or the other. A shoulder on the pin further reduces the likelihood of this happening.Type: GrantFiled: February 3, 2015Date of Patent: August 16, 2016Assignee: Joy MM Delaware, Inc.Inventors: Randy W.
