    Abstract: To be able, in a machine for machining workpieces and showing a spindle with spindle draw bar, to use an arm (10) with a draw bar pin (2) in a machining device for several working operations or separate tool holders (3) or different types of tools, the draw bar pin (2) is arranged in one piece with or in communication with a tool element (4) including in the arm (10). The tool element is shaped to hold tools or the tool holder (3). The draw bar pin (2) and tool element (4) plus eventual existing connecting elements (5, 12, 13) between the draw bar pin and the tool element are arranged displaceable in the arm (10), whereby the draw bar force of the machine's spindle draw bar is utilized to retain the tools or tool holder in the arm. When resetting or replacing the tools or tool holder (3) the draw bar force of the machine's spindle draw bar is made to stop, whereby the draw bar pin (2) of the arm (10) is made by a drawing element (7) shown by the arm, to displace whereby the tools or tool holder is released from an unmoveable or fixed position in the arm. When the arm (10) is to be released from the machine or its spindle for example exchanging an arm, a lock or fixing device (9) shown by the arm (10) is brought into engagement with the arm's draw bar pin (2), tool element (4), a connecting element (5, 12, 13) or another with the draw bar pin connected element and locks or fixes the draw bar pin against displacement, whereby the machine's ejector mechanism or its spindle draw bar can expel the arm.

    Abstract: A quick change tool holder is disclosed which allows tools to be changed while a collet holding the tools is rotating. The quick change tool holder comprises a stationary housing, a quill rotatably supported within the housing, a collet rotatingly engaged by the quill, the collet adapted to releasingly engage a tool. A rotatable sleeve threadingly engages the housing, and rotation of the sleeve in a first direction releases a tool held in the collet for removal of the tool while the collet is rotating. Rotation of the sleeve in a second direction engages the shank of a tool that has been placed within the collet for rotation therewith. The removal or insertion of a tool can be made while the collet is rotating.

    Abstract: An improved chuck for opening and closing a split collet into which a work piece is inserted. The collet is inserted into a central bore in the chuck housing and a threaded end of the collet is threaded into a rotatable annular member located in a counterbore in the rear of the chuck housing. The rotatable annular member has forwardly directed cam surfaces which cooperate with rearwardly directed cam surfaces in the chuck housing. A recess provided in the radially outer surface of the annular member is aligned with a radial bore in the rear of the chuck housing. A cylindrical key rotatable within the radial bore has an eccentric shaft protuding into the recess in the outer surface of the annular member. Turning the key within the radial bore moves the eccentric shaft into contact with a wall of the recess and rotationally biases the annular member. As the annular member is rotated its cam surfaces ride up respective cam surfaces in the chuck housing, thereby displacing the annular member and the collet rearwardly. Rearward displacement of the collet within the chuck forces the split end of the collet against the front of the chuck housing so as to securely hold the work piece.
