Abstract: A cord has a plurality of graduated segments. The ends of each segment are defined by eyelets through which tees may be inserted to secure the cord to the ground in a figure "4" configuration. The ball is placed within the confines of the triangular portion and its location is marked by a pair of clips. The segment of the triangular portion which corresponds to a hypotenuse includes graduations spaced further apart than the graduations of the segment forming the base of the triangular portion. The position of the golfer's feet in relationship to the ball are marked by another series of clips on the segments.

Abstract: Apparatus for feeding bar stock through the chuck of an automatic lathe. The apparatus is moved laterally by the turret to form shallow notches in the surface of the bar stock. The notches in the bar stock are gripped during longitudinal movement of the turret to advance the bar stock into the work area. A pair of cutting elements are adjustably located on one end of the apparatus to grip bar stock of various diameters. Guide blocks having interchangeable bushings to accommodate bar stock of different diameters are also disclosed for supporting the bar stock for rotation by the chuck.

Abstract: A method of preparing a program for numerically controlled machine tools is disclosed involving the use of an aid comprised of a model representing the workpiece to be machined and the tooling to perform the machining process, mounted to have a capability for relative movement along axes corresponding to the relative movement occurring during the machining process. Standardized preset tools and tool holders are established for use in the actual machining processes and corresponding model representations of such standardized preset tools and tool holder combinations are provided which can be located in the model in the same relative position as the corresponding actual tools and tool holders will be located in the machine tool. In preparing the NC program, a machinist prepares a machining process, selecting tools and holders from the available standardized preset tools, and specifies the various machining steps, spindle speeds, in-feed rates, etc. to be utilized in machining the workpiece.
