Patent number: 9447663Abstract: An abrasive perforator tool with a bypass flow channel. The tool comprises a tubular body or housing with perforating nozzles in the sidewall. A sleeve assembly inside the central bore of the tool provides for sequential deployment of first and second sleeves. Prior to deployment of the sleeve assembly, pressurized fluid can be passed through the tool to operate other tools beneath the perforator in the bottom hole assembly. Deployment of the first sleeve diverts pressurized fluid through the nozzles for perforating. Deployment of the second sleeve redirects the pressurized flow through the outlet of the tool to resume operation of other tools below the perforator.Type: GrantFiled: May 21, 2014Date of Patent: September 20, 2016Assignee: THRU TUBING SOLUTIONS, INC.Inventors: Michael L. Connell, Robert J. Farkas

Patent number: 9194181Abstract: A motor and rotor catch assembly for preventing loss of broken motor parts downhole. The assembly comprises a motor including a rotor supported inside a stator housing. A rotor bolt is connected to the upper end of the rotor, and is supported for axial movement within a rotor bolt housing from a running position to a deployed position. If the stator housing breaks or backs off, the attached rotor bolt shifts to the deployed position. In the deployed position, the bolt substantially reduces flow to the stator housing and simultaneously opens bypass ports to vent fluid to the annulus instead. In this way, the rotor is prevented from spinning rapidly, the diverted fluid creates a pressure change that alerts the operator to the motor failure, and the diverted fluid allows continued removal of debris and cuttings from the well bore.Type: GrantFiled: August 30, 2012Date of Patent: November 24, 2015Assignee: Thru Tubing Solutions, Inc.Inventors: Michael L. Connell, Andrew M. Ferguson, Roger L. Schultz, Brett A. Fears, Robert J. Farkas

Publication number: 20080250584Abstract: A cleaning apparatus for cleaning containers on a construction site comprises an armature having a cylindrical body with an end wall. The armature is covered with a scrubbing material and is constructed for attachment to a shaft rotated by a power source such as a hand-held power drill. The armature includes keying structure that precludes rotation relative to the shaft. In one embodiment, the legs of a stirring paddle at the distal region of the shaft are inserted into corners of a square cylindrical armature to key them together. In another embodiment, the armature is constructed of a circular cylindrical body with identical end caps attached thereto, and the end caps are keyed to the shaft. A user handle may be mounted on the shaft to provide better control of the apparatus during a cleaning operation.Type: ApplicationFiled: April 9, 2008Publication date: October 16, 2008Inventors: Robert J. Farkas, Robert J. Farkas, Glenn D. Farkas

Patent number: 6439866Abstract: A rotary device, such as a downhole motor, with a rotary wave seal assembly. The seal assembly is formed by a sinuous or non-linear circumferential gland or groove and an annular seal member, such as an O-ring, supported in the groove. The device further includes at least one thrust bearing assembly for transmitting axial pressure from the bearing housing to the drive shaft. Each thrust bearing comprises a self-lubricating thrust washer as the bearing element. Still further, where the rotary device comprises two coaxial tubular structures that are not to rotate relative to each other, an anti-rotation means is provided. The anti-rotation means includes a cylindrical pin received in mating longitudinal, radiused grooves in the outer wall of the innermost elongate member and the inner wall of the outermost tubular member. The anti-rotation means includes a cylindrical pin received in the mating longitudinal grooves.Type: GrantFiled: April 3, 2000Date of Patent: August 27, 2002Assignee: Cudd Pressure Control, Inc.Inventors: Robert J. Farkas, Bryan F. McKinley, Andrew M. Ferguson
