Our invention relates to a frictional clutch adapted to be operated by a quick-shift device, and, as shown in the drawings, is applied to a head-stock of an engine-lathe for transmitting power to the lathe-spindle.
Having described our invention, we claim:
1. In combination with the spindle of a machine-tool, a loose wheel thereon for driving the spindle, an internal wheel fixed to the spindle, and concentric with the first-named wheel, said internal wheel being formed with an annular grooved periphery, two friction segments located in said groove, an expanding device between two of the abutting ends of said segments, means for actuating the said device, and a wedge between the other two abutting ends of said segments for taking up wear and lost motion, substantially as described.
2. In combination with the spindle of a machine-tool, a loose wheel thereon for driving the spindle, an internal wheel fixed to the spindle, and concentric with the first-named wheel, said internal wheel being formed with an annular grooved periphery, two friction segments located in said groove, an expanding device between two of the abutting ends of said segments, means for actuating the said device, a wedge between the other two abutting ends of said segments for taking up wear and lost motion, and bolts taking through said annular periphery and into said segments holding them slightly movable in position, substantially as described.
