Abstract: A keyless arbor device for securing a tool, such as a drill bit, to a driver. At least one drive key is pivotally combined with the arbor. A threaded member and an outer sleeve are combined with an arbor.

Abstract: An arrangement for centering and clamping of work pieces comprises tension levers swingably supported on a base plate, the tension levers of which are arranged coaxially on a pivot, while the other tension lever is supported on a second pivot which has the same distance to the center of the arrangement as the hinge pin. The contact surfaces with which the tension levers grasp a work piece, are designed so that the perpendicular line extends on the particular tangent at the contact point between contact surface and work piece through the center of the arrangement. This forces the work piece, independently of its diameter, continuously into the center in the clamping process and, consequently, centers it. Due to the arrangement of the tension levers, inserting work pieces transversely to the chuck axis is possible in spite of the center clamping process.

The system includes pairs of spindles, one a conventional spindle for drilling holes larger than about 0.125 inches, and the other a high speed spindle for drilling holes in the range of about 0.003 to 0.125 inches. The high speed spindle includes a stationary spindle body carrying the stator of the rotary drive motor.

The preferred quick release means is a spring loaded shuttle positioned in an opening radially through the body member and in communication with the bore. The preferred torque transmitting means is a pair of corresponding, opposed surfaces disposed on the bore and working member, respectively.

Abstract: The jig of this invention holds a radial array of separate materials together so that they can be glued, welded, or otherwise secured together. The jig is then removed. A plurality of fingers are pivoted to a common support, and elastic means are used to urge the fingers together to tightly grip the radial array of materials to be held. The finger surfaces are angular to correspond to the angle of the materials to be held and for a cross shaped array of materials, the finger surfaces are at 90.degree. to each other. The fingers have shanks that project beyond the hinge or pivot point and these projecting shanks may be used to open up the fingers by manually grasping the projecting shanks and thereby overcoming the elastic means which normally urges the fingers together.

Abstract: A self-energizing lathe chuck is provided with a pair of interiorly mounted clamping shoes which serve to grip a piece of stock directed through an aperture in the chuck so as to retain the stock in a desired working position. The clamping shoes are mounted to a pair of pivot plates which rotate within slots provided in the chuck, and a spring is utilized to bring the clamping shoes into engagement with the stock so as to retain the same in a working position. A movement of the stock through the chuck in one direction results in the clamping shoes being released from engagement with the stock, while any attempted movement of the stock in the reverse axial direction is prevented by the engagement of the clamping shoes with the stock.

Abstract: A lathe chuck jaw for a lathe chuck having a radially moving actuator which radially moves the jaw in to and out from the workpiece. A jaw base part is rigidly connected to the actuator.
