ABSTRACT:
A safety guide for kelly spinner hoses in drilling rigs and a plurality of said safety guides in combination with kelly hoses and a rotary hose. Each safety guide comprises a pair of opposed rings, each adapted to receive and guide a kelly spinner hose, and a device for securing the rings to a rotary hose substantially in a plane perpendicular to the axis of the rotary hose. Advantageously, each ring has a rigid integral loop member and the securing device comprises a flexible band passing through said loop members. It is preferred to secure the band to the rotary hose with a buckle. In the combination, a plurality of the safety guides are spaced along the length of the rotary hose, preferably substantially equidistant.
