Description

    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application is a continuation of U.S. patent application Ser. No. 17/100,649, filed Nov. 20, 2020, entitled Tie Drill and Lag Screw Inserter Device for the Rail Industry, which claims priority to U.S. Provisional Application No. 62/938,772, filed Nov. 21, 2019, all of which are herein incorporated by reference in their entirety.
  • FIELD OF THE INVENTION
  • The present invention relates to the rail industry and, more particularly, to one or more devices for drilling a hole through a plate and into a wooden tie and inserting a lag screw.
  • BACKGROUND OF THE INVENTION
  • Currently, there are limited methods for drilling a hole through a plate and into a wooden tie and inserting a lag screw. Presently, two different and distinct tools are used for each of these operations. A tie drill tool is used to drill a hole through a plate and into a wooden tie. A lag screw inserter tool is then utilized to insert and put the lag screw into the hole in the plate and into the wooden tie. The current methods and tools use hydraulics and internal combustion engine. The weights for each of the tools can be over 60 pounds for each type of tool. There is a need for a portable device configured to easily drill a hole through a plate and into a wooden tie or to insert and put a lag screw into the hole in the plate and into the wooden tie. Currently, there also are no battery-operated tie drill and lag screw inserter devices that operate as one tool. A single tool capable of both drilling a hole through a plate and into a wooden tie and inserting a lag screw would be a great improvement.
  • Aspects of this disclosure relate to a portable device for drilling a hole through a plate and into a wooden tie and/or inserting a lag screw into the hole in the plate and into the wooden tie. The portable device may comprise a tie drill device, a lag screw inserter device, or a device capable of functioning as both a tie drill device and a lag screw inserter device. In various embodiments, the portable device may include a replaceable and removable drill, a handle, and a quick connect system to connect the drill to the portable device. The drill may comprise an electric-powered drill with a rechargeable battery that provides power to the portable device. In various embodiments, the portable device may include a gear ratio and gear reduction system configured to allow a user to change speed and torque settings for the portable device independent from the drill. The portable device may also include a preset distance system setting with a knob and a spring-guided mechanism with preset distances to assist the user with setting the distance. The portable device may also include a leveling plate to ensure that each drill bit and lag screw is aligned and installed vertically and a removable drill guard to protect the drill.
  • In various embodiments, the portable device may include a handle assembly configured to connect the removable drill to the portable device. In some embodiments, the handle assembly may be configured to connect the removable drill to a drive shaft of the portable device. The handle assembly may include a drill face plate and one or more fastening straps to removably secure the drill to the portable device. The handle assembly may also include one or more side plates to connect the handle assembly to the body of the portable device. In some embodiments, the handle assembly may include a drill guard structure configured protect the removable drill when connected to the portable device.
  • In some embodiments, the portable device may include two quick connect/disconnect components: a first quick connect/disconnect component configured to make the drill removable and replaceable and a second quick connect/disconnect component configured to receive a drill bit or a lag screw socket. The second quick connect/disconnect component may enable the portable device to be used as a tie drill device or a lag screw inserter device by interchangeably connecting either a drill bit or a lag screw socket to the portable device. As such, in some embodiments, the portable device may allow a user in the rail industry to use one tool to perform two different and distinct functions. When a drill bit is connected to the portable device, the portable device may allow a user to drill a hole through a plate and into a wooden tie. The user may then disconnect the drill bit and connect a lag screw socket to the portable device in order to insert a lag screw into the hole in the plate and into the wooden tie.
  • These and other objects, features, and characteristics of the invention disclosed herein will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings, all of which form a part of this specification, wherein like reference numerals designate corresponding parts in the various figures.
