Patent number: 11105156Abstract: A pullback device for attaching to a rotary drill bit that has a pair of wrench flats on its base without disassembling or removing the rotary drill bit from a drill string. The pullback device includes an anchoring portion including a collar configured to engage with the wrench flats of the rotary drill bit. The pullback device includes a plurality of arms, each of the plurality of arms having a first end including an attachment location configured to attach product to the pullback device for pullback of the product by the drill string, and each of the arms including a second end opposite the first end, the second end attached to the collar.Type: GrantFiled: January 31, 2020Date of Patent: August 31, 2021Assignee: Vermeer Manufacturing CompanyInventors: Tyler J. Dorin, Jacob Richard Smith, Michael D. Langenfeld

Patent number: 10711520Abstract: A drill head includes a drive shaft that has an uphole end and a downhole end. The downhole end includes drive features that are torque transmitting and radial load bearing. The drill head also includes a coupling that includes drive features that are torque transmitting and radial load bearing. The drive features of the coupling are sized and shaped to mate with the drive features of the drive shaft. The coupling includes an axial fluid flow passage and a radial fluid flow passage. The radial fluid flow passage is in communication with the axial fluid passage, and fluid flow is permitted between the drive features of the drive shaft and the drive features of the coupling.Type: GrantFiled: May 1, 2018Date of Patent: July 14, 2020Assignee: Vermeer Manufacturing CompanyInventors: Michael D.

Patent number: 10227832Abstract: Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as “torque-less” connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.Type: GrantFiled: March 14, 2017Date of Patent: March 12, 2019Assignee: Vermeer Manufacturing CompanyInventors: Michael D. Langenfeld, Randy R. Runquist
