The pantograph armature includes a motorized drive shaft with a drill tip for carving an outside surface of a crayon body, as well as a guide tip for tracing along a guide template that directs where the drill tip carves. In some embodiments, the guide template includes a stationary bridge support and a plurality of removable carving bucks that insert into one of multiple openings on the bridge support. The surface features of each of the carving bucks may be traced by the guide tip to generate a corresponding carving on the surface of a crayon body.

A rotary laser engraving device for retaining and rotating an object to be engraved is provided and includes a frame, a first support assembly and a second support assembly mounted on the frame. The first support assembly includes a first set of rollers for supporting a first end of the object to be engraved. The second support assembly includes a second set of rollers for supporting a second end of the object to be engraved. The first set of rollers and the second set of rollers are offset diagonally from the frame. At least one longitudinal adjustment mechanism and at least one vertical adjustment mechanism are carried by the frame and allow to adjust the longitudinal and vertical separation, respectively, between the first and second sets of rollers. A motor assembly is provided to rotate one of the first and second sets of rollers to rotate the object to be engraved.

An engraving tool for allowing a craftsperson to engrave an object, such a ring or other jewelry, while allowing a discrete number of degrees of freedom but restricting all others. In an embodiment, an engraving tool includes a base portion coupled to a manipulator housing portion that is rotatably attached to the base portion such that the manipulator housing portion may be rotated in a first degree of freedom (e.g., rotated in a horizontal plane with respect to a vertical axis of the base portion). The engraving tool further includes a manipulator secured to the manipulator housing portion in a U-shaped socket such that the manipulator is configured to be rotated in a second degree of freedom (e.g., rotated in one particular vertical plane with respect to the horizontal plane). A ring holder is attached to manipulator and configured to secure a ring for engraving.

A tag cassette assembly for use in connection with an engraving process carried out in an engraving machine includes a single piece cassette body of plastic material, the cassette body including a first major side and a second major side and a periphery formed by minor edges; a tag secured in a capture space of the cassette body; wherein the cassette first major side is configured to provide access to a first side of the tag to facilitate engraving and the second major side is configured to provide access to a second side of the tag to facilitate engraving.

Platform movement systems and methods of using the same. A system for moving a platform of the present disclosure can include a first actuator pivotally attached to a base, the first actuator having a first rod positioned therethrough and configured to move the first rod in a first direction and an opposing second direction along a first rod axis; a second actuator pivotally attached to the base, the second actuator having a second rod positioned therethrough and configured to move the second rod in a first direction and an opposing second direction along a second rod axis; an arm attached to the base using an arm connector; and a platform coupled to the first rod, the second rod, and the arm, the platform configured to move about the base upon operation of the first actuator and/or the second actuator.

A rotary laser engraving device for supporting and rotating an object to be engraved during a laser engraving process is provided and includes a support frame. The support frame may include a central bar, a stationary vertical post and a movable post movable along a length of the central bar. A first support assembly is movably mounted on the frame, such as on the stationary vertical post, and includes a first pair of rollers for supporting a first end of the object to be engraved. A second support assembly is movably mounted on the frame, such as on the movable post, and includes a second pair of rollers for supporting a second end of the object to be engraved. At least one longitudinal adjustment mechanism and at least one vertical adjustment mechanism are carried by the frame and allow to adjust the longitudinal and vertical separation, respectively, between the first and second pairs of rollers. A motor assembly is provided to rotate one of the first and second pairs of rollers to rotate the object to be engraved.

A rotary laser engraving device for retaining and rotating an object for engraving includes a frame, a first support assembly and a second support assembly mounted on the frame. To support the object the first support assembly includes a set of driven rollers and the second support assembly includes a set of free rollers, each being diagonally offset from the frame. The second support assembly is configured to slidably move on the frame to vary a longitudinal separation between the driven rollers and the free rollers. The second support assembly further includes a vertical adjustment assembly configured to move the free rollers vertically to vary a vertical separation between the driven rollers and the free rollers. In some aspects, the first support assembly also includes a fixed vertical adjustment assembly configured to move the driven rollers vertically to vary a vertical separation between the driven rollers and the free rollers.

A rotary laser engraving device comprising a frame having a centroidal axis and comprising a central bar arranged in a longitudinal direction and off set horizontally from the centroidal axis. A first support assembly is carried by the frame for supporting a first end of an associated object to be engraved. A second support assembly is carried by the frame for supporting a second end of the associated object to be engraved. A longitudinal adjustment mechanism is carried by the frame and being configured to restrict movement of the second support assembly in a longitudinal direction along the central bar. A vertical adjustment mechanism is carried by the frame and being configured to move the second support assembly vertically with respect to the central bar.
