Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. 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.

The present invention provides a reciprocal vibration type electric engraving pen driven by a main transmission shaft to operate. The engraving pen contains a rear shell assembled with a front shell. The rear shell positions the main transmission shaft. A top front of the driving shaft is assembled with an off-centered driving bead, and the front shell is assembled with a driven shaft. The engraving pen is characterized in that a rear end of the driven shaft is assembled radially with a driven pillar, and the driving shaft is formed integrally with a connection barrel.

10 Accordingly, when the main transmission shaft drives the driving shaft to rotate, the driving bead revolves on a circular track simultaneously. When the driving bead revolves by one turn, the driven pillar is hit twice and vibrates double times. Furthermore, the driven shaft can rotate clockwise and counterclockwise, and the lifetime is extended.

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.

The proposed actuator of engraving machine relates to decorative machining of hard materials, and can be used in arrangement of facades and monuments. A permanent magnet and a core with a pivot are concentrically fixed in an upper part of a housing. An electric coil is placed on a cylindrical frame of nonmagnetic material and can move in the axial direction in a ring gap between the core and the permanent magnet together with a pusher fixed in two circular elastic membranes, spaced in the axial direction and fixed in the housing along an external contour. A shank is fixed on the pusher under the membranes, having a central part extending through a bottom cover of the housing. It has a hollow axial opening, wherein a removable impact tool is mounted. The design is simple and reliable. Durability, accuracy and speed of engraving of the actuator are improved.

A portable rail system for mounting an engraving device includes rails and crossbar members that are precisely joined, and include height adjustment devices for incrementally adjusting the height of the rail system relative to a work surface or contact surface, thus making the portable rail system capable of being assembled and disassembled at a work site to enable the use of an engraving device, such as a CNC router engraving systems, in situ, or on-site, rather than in a workshop. The portable rail system enables the use of a CNC router device or other engraving device on vertical surfaces.

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.
