Prindle & Williamson - patent attorneys
Having thus described my invention, what I claim is:
1. In a machine for boring, tapping, etc. the combination of a rotatable and axially movable tool spindle, an arm or projection connected therewith, a rotatable part having a surface that engages such arm or projection to rotate the spindle and move it axially and that inclines rearward with reference to the direction of rotation, so that, as the spindle moves axially, said arm tends to move out of contact with said inclined surface, whereby friction between them is lessened, and means to rotate said rotatable part.
2. In a machine for boring, tapping, etc., the combination of a rotatable and axially movable spindle, an arm or projection connected therewith, a rotatable part having a surface that engages such arm or projection to rotate the spindle and move it axially during the feeding operation of the spindle, while performing its work, which surface inclines rearward with reference to the direction of its rotation, so that as the spindle moves axially, it tends to move out of contact with the said inclined surface, whereby friction between them is lessened, means to rotate said part, and spindle feeding means in addition to said inclined surface. |
