Abstract

417,577. Chucks. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE, 8, Rue des Vieux Grenadiers, Geneva, Switzerland. June 2, 1934, No. 16514. Convention date, Feb. 1. [Class 83 (iii).] In a tool-holding socket, means are provided for clamping or positively ejecting the tool on rotation of the socket spindle. The tool 5 has a tapered shank 4 held in a socket in the end of the machine spindle 3 by means of a clamping rod 6 screwing into the end of the shank 4. A collar 9 on the rod 6 is held between the end of the spindle and a nut 8 screwing thereon so as to rotate within the spindle without axial movement. Clutch teeth 10 on the spindle are normally pressed by a spring 19 into engagement with teeth 11 on a driving member 12 which is splined at 14 within the pinion 16 which effects the drive. To remove the tool 5, the spindle 3 is raised by a quill 2 and hand-operated pinion 21, causing the member 12 to engage the boss of the driving gear 16 to prevent further axial motion thereof and then disengaging the clutch teeth 10, 11 and inserting a squared end 17 of the rod 6 in a similar aperture in the member 12. Rotation of the spindle by means of a hand tool engaging teeth 22 thereon will then unscrew the shank 4 from the rod 6 and force the shank axially out of the socket, rotation of the rod being prevented by the squared end 17. To insert a tool 5, the spindle is again raised to the position shown in the Figure, the tool screwed on the rod 6, and the spindle rotated to cause the rod to draw the shank 4 into the socket.
