  • Directional boring head with deflection shoe and method of boring
    Patent number: 5490569
    Abstract: A boring apparatus (10) is disclosed which includes a casing (16) mounting a drill bit (42) and a deflection shoe (22). The cutting circle of the drill bit is offset from the centerline axis (18) of the casing (16). At least a portion of the deflection shoe (22) lies outside the cutting circle of the drill bit so that the deflection shoe causes the boring apparatus to deflect as the borehole is drilled. Rotation of the casing 16 a predetermined distance will cause the boring apparatus to change the direction of deflection. A continuous rotation of the casing will permit the boring apparatus to bore straight ahead. The drill stem (32, 68, 74) rotating the drill bit can be mounted concentric with the centerline axis of the casing and offset therefrom, at an angle relative to the centerline axis and can be sufficiently flexible to be curved to accommodate the signal beacon housing.
