Abstract:
A brake device for engaging an inner surface of a drill string within a borehole. The brake device has a driving member that defines a plurality of wedge surfaces, a brake retainer that receives at least a portion of the driving member, and a plurality of braking elements positioned in contact with at least a portion of the outer surface of the driving member. The brake retainer has a biasing member that is operatively coupled to the driving member. The biasing member of the brake retainer biases the driving member in a proximal direction relative to the longitudinal axis of the drill string to position the wedge surfaces in contact with corresponding braking elements, and the wedge surfaces drive the braking elements radially outwardly to engage the inner surface of the drill string. The brake device is not coupled to an inner tube assembly.

Claim (Index 22):
A drilling system comprising:\n a drill string having an inner surface and a longitudinal axis; an inner tube assembly; and a brake device configured to engage the inner surface of the drill string within a drill hole, the brake device being configured for axial movement relative to the longitudinal axis of the drill string, the brake device comprising:\n a driving member having an outer surface that defines a plurality of wedge surfaces; \n a brake retainer having an inner surface that defines a central bore that receives at least a portion of the driving member, wherein the brake retainer defines a plurality of radial openings positioned in communication with the central bore, and wherein the brake retainer comprises a biasing member that is operatively coupled to the driving member; and \n a plurality of braking elements positioned in contact with at least a portion of the outer surface of the driving member, \n wherein the biasing member of the brake retainer is configured to bias the driving member in a proximal direction relative to the longitudinal axis of the drill string to position the plurality of wedge surfaces of the driving member in contact with corresponding braking elements of the plurality of braking elements, and wherein the plurality of wedge surfaces of the driving member are configured to drive the plurality of braking elements radially outwardly into corresponding radial openings of the brake retainer to engage the inner surface of the drill string, and wherein the brake device is not coupled to the inner tube assembly.
