摘要： An apparatus for actuating a collet or other chucking devices which includes a rotatable cylinder and double acting piston assembly positioned around a tubular draw member for causing a collet or the like to reciprocate in a lathe spindle. The piston, which is rigidly secured to the drawing member, is provided with a pair of spring-biased, piston operated valves for admitting fluid under pressure to the expansible chambers defined by the piston and the cylinder walls as well as venting the same for the purpose of causing the piston to reciprocate in the cylinder. The valves also include check means for trapping fluid under pressure in either of the chambers should the pressure of the fluid source be reduced. The drawing member generally comprises two concentric tubes, the inner one having a pair of slots in its external surface which cooperate with the internal surface of the outer tube to form a pair of passageways for providing fluid under pressure to the aforementioned expansible chambers.

摘要： The invention relates to a taper turning attachment for a lathe or the like and includes a template which may be selectively moved to either a first position where it will engage a portion of the cross-slide or to a second position wherein the movement of the cross-slide is unaffected. The template is either raised or lowered by means of a piston and cylinder arrangement laterally mounted on the bed of the lathe and may be automatically actuated through the action of an appropriate programming mechanism. The cross-slide includes a downwardly extending lug which is provided with a roller for the purpose of engaging the guide face of the template during the lateral movement of the cross-slide with respect to the carriage thereby causing the tool to move in a path paralleling the template guide face. The angle of the guide face with respect to the spindle is angularly adjustable in the plane in which the cross-slide and carriage move.

摘要： A self-centering, radially reciprocating jaw chuck for machine tools and the like comprising a chuck body member, a plurality of master jaws secured to the body member, each of the master jaws having a pair of circumferentially spaced fixed portions rigidly secured to the body member and a radially reciprocable portion positioned circumferentially between the fixed portions. Resilient means integral with both the fixed portions and the radially reciprocable portion connect these portions, and a work gripping member is secured to each of the radially reciprocating portions. Axially reciprocable means is provided within the body member for radially reciprocating the radially reciprocable portions, and work gripping members attached thereto, whereby flexure of the resilient means provides a self-centering action of the work gripping members with respect to the longitudinal axis of the chuck and the work.

摘要： This invention is a machine tool feed chuck including a cylindrical body having a longitudinal bore through which a bar passes. The body is provided with opposed longitudinal slots forming leaves comprising jaws for holding the bar under tension. The leaves are urged toward each other at one end of the cylindrical body in order to obtain tension on the bar. In order to reduce the amount of deflection of the leaves between the working and inoperative positions, stop plugs are mounted in the leaves of the cylindrical body, the stop plugs extending across the slots into engagement with a portion of the opposite leaf, thereby preventing the leaves under tension from closing fully at the front end, and holding the chuck partially open when in the inoperative position.

摘要： This disclosure is of an attachment for lathes by means of which highly accurate work can be done so that the attachment may be used, for example, by forming contact lenses and in which two slides are provided, a cross-slide for setting the cutting tool on the center of the lathe spindle, and another slide on which a swivel tool-carrying member, which arrangement allows the tool to be fed in without changing radius for which the tool-carrying member is set. This disclosure also provides readily adjustable means for setting the radius of the cut.

摘要： This disclosure is of a stop for an automatic machine tool which is motivated under control of a programming arrangement in which a reduced length of travel of the stop is produced by reversing the direction of movement of the stop with reference to the usual stop screws and in which the usual stop drum is positioned farther forward on the machine for easier setting by the operator and still keep the actual stop at the ideal position with reference to the carriage.
