摘要： A machine for boring a shaft in earth strata or the like. An annular support ring means having an outside diameter approxiately equal to the diameter of the shaft which is selectively engageable or disengageable with the shaft wall by the use of clamping means is disclosed. A carriage means which is slidably mounted on the annular support ring means and orbital thereabout is also disclosed. A rotary cutting wheel means having a diameter substantially smaller than the diameter of the shaft is mounted on the carriage means and is axially displaceable with respect thereto for movement in a direction which may be parallel or inclined with respect to the axis of the shaft. Various drive means for moving the carriage means circumferentially about the annular support ring means, and for moving the rotary cutting wheel means in an axial direction with respect to the carriage means, and for rotating the rotary cutting wheel means are described. The use of the machine to make an overlapping helical path cut in earth strata whereby a generally cylindrical shaft is created is also described.

摘要： A tunnel boring machine for controlled boring of an elongated curvilinear tunnel in earthen strata. The tunnel boring machine comprises: cutting means for engaging the tunnel face and removing material therefrom to elongate the tunnel during a cutting strocke; elongated body means for supporting various machine components; elongate thrust arm means for urging the cutting means against the tunnel face during a cutting stroke and for advancing the elongated body means along the tunnel between cutting strokes, the thrust arm means being extendable and retractable from the body means along a thrust arm axis coaxial a machine longitudinal axis; forward lateral positioning means operably mounted on a forward portion of the body means for selectively controlling the lateral positioning of a forward portion of the body means within the tunnel; rear lateral positioning means operably mounted on a rear portion of the body means for selectively controlling the lateral positioning of the rear portion of the body means within the tunnel; forward transverse positioning means operably mounted on a forward portion of the body means for selectively controlling the transverse positioning of a forward portion of the body means within the tunnel; rear transverse positioning means operably mounted on a rear portion of the body means for selectively controlling the transverse positioning of the body means within the tunnel; whereby the machine longitudinal axis is selectively transversely and/or laterally positionable relative the longitudinal axis of the tunnel through the use of the forward and rear lateral positioning means and the forward and rear transverse positioning means; and tunnel gripping means operably mounted on the body means for selectively grippingly engaging the peripheral sidewall of the tunnel to prevent rearward movement of the body means during a cutting stroke. Various methods of operation of the machine are described.
