Patent number: 8720128Abstract: A method to disassemble a mast assembly having a substructure including a first and second section, a first and a second cylinder, and a lower mast section. The method includes the steps of disengaging a pair of front mast legs of the lower mast section from a pair of front leg supports. The pair of front leg supports are moved from an operational to a transport position. The lower mast section is lowered from a vertical to a horizontal position by retracting the first cylinder and the second cylinder. A mast center spreader is thereafter removed from the lower mast section. A center drill floor section is removed from between the first substructure section and the second substructure section so that a combination of the first substructure section, the first cylinder and a portion of the lower mast and a combination of the second substructure section, the second cylinder and a portion of the lower mast may be transported.Type: GrantFiled: October 1, 2012Date of Patent: May 13, 2014Assignee: Woolslayer Companies, Inc.Inventor: Dewayne G.

Patent number: 8353132Abstract: A method and an apparatus for a sectional mast assembly for erection and disassembly of a rig. The sectional mast assembly includes a bottom section having at least a back and a pair of opposed sides with each of the opposed sides having at least one pivoting ratchet support. A scoping dog assembly is moveable on a track on the bottom section. The scoping clog assembly includes wheels which engage the track and a pivoting ratchet support. A cylinder extends between the bottom section and the scoping dog assembly to move the scoping dog assembly on the track. The pivoting ratchet support of the scoping dog assembly engages each of the mast sections in sequence to raise the entire mast assembly.Type: GrantFiled: February 16, 2011Date of Patent: January 15, 2013Assignee: Woolslayer Companies, Inc.Inventors: Dewayne G. Vogt, Paul Landis

Patent number: 4598509Abstract: Method and apparatus for raising and lowering a telescoping mast. A telescoping mast having an upper section slidably received within a lower section is pivotally connected to a base in a horizontal position. A line is connected to the lower end of the upper section and is placed over a pulley mounted on the upper end of the lower section and secured to the base. Upward pivoting of the lower section moves the mast to a vertical position while the upper section is extended by action of the line. Lowering the mast from the vertical position causes contraction of the upper section into the lower section.Type: GrantFiled: June 24, 1985Date of Patent: July 8, 1986Assignee: Lee C. Moore CorporationInventors: Homer J. Woolslayer, Cecil Jenkins, Dewayne G. Vogt
