Abstract
Abstract The earth boring machine includes a stationary horizontally disposed frame with guide tracks to straddle a trench next to a pavement. A shaft for a drill bit, supported under the frame, is driven by a motor mounted on a carriage riding on the guide tracks. A pavement aligning member connects to one end of the frame to extend downward over the side of the pavement under which the earth is to be bored. A carriage driver pulls the carriage towards the pavement aligning member and pulls the frame against the side of the pavement in order to enable the drill bit to bore a hole in the earth under the pavement while aligning and clamping the boring machine during the boring operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
267 words
An operably aligned and clamped earth boring machine for boring horizontal holes in earth under a pavement, said boring machine comprising: a. a stationary horizontally disposed frame having longitudinally extending laterally spaced guide tracks; b. a pavement aligning member connected to the frame at one end thereof to extend downward over one side of the pavement while a portion of said frame is positioned on top of the pavement; c. a carriage having wheels rotatably disposed on the guide tracks; d. a motor mounted on the carriage; e. a rotatable hollow shaft disposed on the underside of the frame; f. a drill bit fixedly connected to one end of the hollow shaft; g. a first shaft support member suspended from the carriage to rotatably support the shaft and to move the shaft with the carriage; h. a second shaft support member suspended from the frame on the other side of the pavement between the first shaft support member and the pavement aligning member to support and guide the shaft; i. coupling means connecting the shaft and the motor to enable the motor to rotate the shaft and the drill bit; and j. a carriage driver connected to the frame and to the carriage to pull the frame so that the pavEment aligning member presses against the side of the pavement, and to pull the carriage to move it on the tracks of the frame towards the pavement aligning member in order to enable the drill bit to bore a hole in the earth under the pavement while aligning and clamping the boring machine during the boring operation.
Claim 2
Dependent Claim
