Abstract
A hand powered impact boring tool is used to bore small diameter holes underneath obstructions so utility cables can be buried underground and beneath those obstructions. Making use of a manual powered slide hammer striking against a forward anvil creates the impact force that drives the shaft and tip through the ground. Sliding the hammer backwards against the reverse anvil will back the tool out of the ground leaving a hole for cable to be passed through.
Description
BACKGROUND OF THE INVENTION

The Hand Powered Impact Boring Tool concerns the installation of utility cables underneath obstructions that cannot be removed or gone around, such as a sidewalks. Buried utilities such as Fiber optic, coaxial, phone, low voltage, invisible dog fence cable or other small diameter cable can be buried in the void/hole created by this portable hand powered device. The tool bores through the ground in a forward and reverse motion similar to the Two-Way Ground Burrowing Device, U.S. Pat. No. 3,407,884, Kazimierz Zygmunt, Tadeusz Gerlach, Filed Apr. 11, 1967; Published Oct. 29, 1968. The tool does not require an external power source but utilized an operator powered Slide hammer impact/percussive action similar to the Percussively-Driven Tool, U.S. Pat. No. 875,940, Daniel Lee Mason, Filed Aug. 30, 1904; Published Jan. 7, 1908. The tip impacting with the ground and creating the void/hole is of similar design to the Small Diameter Impact Boring Tool Impact Head, U.S. Pat. No. 5,934,386, Glen Prater, Jr., William P. Hnat, Robert L. Collins, Songnian Wang, Filed Jul. 6, 1998; Published Aug. 10, 1999.


BRIEF SUMMARY OF INVENTION

Hand powered impact boring tool allows the burial of utility cables under obstructions without the destruction or removal of the obstruction.


BRIEF DESCRIPTION OF DRAWING

Figure A, is the hand powered impact boring tool. 1, tip. 2, shaft. 3, forward anvil. 4, reverse anvil. 5, slide hammer with handle. 6, slide rail. Figure B, is a close up of the tip. Figure C, is the slide hammer in the forward position. Figure D, is the slide hammer in the rear position.







DETAILED DESCRIPTION OF THE INVENTION

The hand powered impact boring tool works by impact propelling the tip and shaft underneath obstructions such as a sidewalks. The use of this tool does not require an external power source other than the operator. The use of the tool's built in slide hammer is what propels the tip and shaft through the ground. Placing the tip in the ground underneath the sidewalk in a pre-dug trench and aligning the shaft with the desired location on the other side of the sidewalk. While in that position and holding the side hammer by the handle, slide the slide hammer forward against the forward anvil. This action creates the percussive driving force. Repeat this action until the shaft is far enough through the ground that it reaches the other side of the sidewalk. Dig down and reveal the tip on the other side of the sidewalk. To remove the hand powered impact boring tool from the ground hold the slide hammer by the handle and slide it against the reverse anvil and repeat until the tool is completely out of the ground. The desired utility cable can then be passed through the void/hole left by the hand powered impact boring tool.

Claims
  • 1. What I claim as my invention is a hand powered impact boring tool having a axial motion, comprising of: (a) A tip located on the end of the shaft.(b) A shaft that continues into the slide rail.(c) A forward anvil at one end of the slide rail dividing the shaft from the slide rail, (forward axial action).(D) A reverse anvil at the opposing end of the slide rail from the forward anvil, (reversing axial action).(e) A slide hammer positioned freely, sliding, between the two anvils and on the slide rail; creating the impact force when striking either anvil.
  • 2. The hand powered impact boring tool is man-powered and does not require an external power source such as electric, hydraulic, or pneumatic.
  • 3. The hand powered impact boring tool makes a linear hole/void in any direction but is intended for horizontal use.
