Abstract:
An automatic lathe system comprising, in combination:a table stand having a rectangular planar top with a plurality of legs mounted to the top and extending downwardly from the top, each leg having a wheel assembly pivotally mounted to a bottom of the leg;a pair of spindle spinning assemblies positioned on opposite ends of the top of the table stand, each spindle spinning assembly having a securement rod rotatably mounted thereon and releasably secured to an end of a spindle for spinning the spindle;a vibration damping assembly including an elongated linear arm having a first end pivotally coupled to the top of the table stand and a second end having a member coupled to the second end and extending downwardly the arm in a perpendicular relationship with the arm, the member having a bottom end with two pairs of wheels rotatably mounted thereon, each pair of wheels spaced from the other pair of wheels to define a groove, wherein the arm may be lowered such that a spindle mounted between the spindle spinning assemblies engages the groove defined by the pairs of wheels and a weight of the arm damps vibration, each wheel of the vibration damping assembly having a thick soft rubber coating for further damping vibration and further accepting a spindle with an initial generally square cross-section;a carriage assembly being adapted to slide on at least one elongated bar extending between each spindle spinning assembly, the carriage assembly having a blade mechanism mounted thereon for engaging a front surface of the spindle secured between the spindle assemblies, the blade mechanism being slidable along an axis perpendicular with respect to the bar and direction of notion associated with the carriage assembly such that the blade mechanism is continuously urged toward the spindle, the carriage assembly further including a carriage motor for moving the carriage by way of a pulley in a forward direction upon the receipt of a forward signal and move the carriage in a reverse direction upon the receipt of a reverse signal only when the carriage motor is actuated;a plastic planar template having a pair of curvilinear elongated side edges defining an outline of a unique spindle, the template mounted in spaced horizontal orientation with respect to the top of the table stand such that an inboard end of the blade mechanism is in sliding abutment with one the side edges of the template and distanced from the spindle in accordance with the outline of the side edge as the carriage assembly moves along the template. wherein the template is removable and remounted so that another one of the side edges may be placed in operative sliding abutment with blade mechanism of the carriage assembly;reverse direction means located at opposite ends of the top of the table stand in line with the carriage assembly, the reverse direction means transmitting the forward signal to the carriage motor when the carriage is moving in a reverse direction and reaches a first end of the top of the table stand, the reverse direction means transmitting the reverse signal to the carriage motor when the carriage is moving in a forward direction and reaches a second end of the top of the table stand;an indexing assembly including a multi-position solenoid fixedly mounted on the carriage assembly and in abutment with the blade mechanism for indexing the blade mechanism away from the spindle a predetermined distance upon the receipt of an index away signal and further indexing the blade mechanism toward the spindle the predetermined distance upon the receipt of an index toward signal, wherein an index toward signal is transmitted to the indexing, assembly upon every transmission of at least one of the forward and reverse signal to the carriage motor, as when the carriage reverses direction;a cut off switch mounted on the top of the table stand adjacent to one of the ends of the top for deactuating the carriage motor and the spinning assemblies upon the abutment of the blade mechanism with one of the spinning assemblies when the blade mechanism resides in constant abutment with a full length of the template.
