Abstract: A system for practicing roping of a steer may include a towing apparatus configured to tow a steer roping practice apparatus across a ground surface, a central anchor device configured to define a fixed anchor point with respect to the ground surface, an elongated guide member attachable at a first end to the central anchor device and attachable at a second end to the towing apparatus to guide the towing apparatus along a circular path about the central anchor device, and a turning device configured to engage the elongated guide member between the central anchor device and the towing apparatus in a manner causing the towing apparatus to make a turn on the ground surface from the circular path. The system may also include a mechanical steer roping practice apparatus movable across the ground surface and removably hitched to the towing apparatus.

Abstract: A method and apparatus for truing a cartridge case with an apparatus including a frame defining a chamber and having a central axis, and a cartridge sleeve defining a cartridge passage with a passage surface for engaging the exterior surface of the body of the case, and a tool extending along the central axis of the frame with a tip end extending into the chamber. The frame may include a tool mandrel portion configured to mount the tool on the frame, and a sleeve mandrel portion configured to mount the cartridge sleeve on the frame. The sleeve mandrel portion may permit the cartridge sleeve and a cartridge case mounted thereon to translate with respect to the frame along the central axis of the frame, the sleeve mandrel portion permitting the cartridge sleeve and a cartridge case mounted thereon to rotate about the central axis with respect to the frame.

Abstract: A mechanical roping steer apparatus for practicing roping of a steer may comprise a support assembly for resting on a ground surface, a rotatable wheel configured to contact the ground surface such that movement of the support assembly across the ground rotates the wheel, and a steer assembly connected to the support assembly. The steer assembly may comprise a frame having a spine structure, a hip structure movably mounted on the frame to move between first and second positions, and a leg structure movably mounted on the hip structure to move between forward and rearward positions, and including at least one leg member. The steer assembly may include an actuation assembly may be configured to move the leg member downwardly toward the ground surface during rearward movement of the leg member and move the leg member upwardly during forward movement of the leg member.

Abstract: A miniaturized steer roping practice apparatus may comprise a mobile base comprising a frame, an axle rotatably mounted on the frame to rotate about a rotation axis in a forward rotational direction for forward movement and a rearward rotational direction for rearward movement, and at least one drive wheel mounted on the axle. The apparatus may further comprise at least one leg movable with respect to the base, a leg actuation assembly configured to move the at least one leg in conjunction with rotation of the drive wheel, a cover mounted on the mobile base and having an exterior surface with a resemblance to a steer, and a motivating assembly configured to drive the axle in the forward rotational direction using stored energy. The motivating assembly may be configured to store energy by rotation of the axle in the rearward rotational direction.

Abstract: A mechanical roping steer apparatus for practicing roping of a steer may comprise a steer assembly having a front and a rear. The steer assembly may comprise a frame and a leg assembly mounted on the frame and including at least one leg member being movable with respect to the frame, the at least one leg member having a lower end movable along an arc. The steer apparatus may further comprise an actuation assembly configured to engage a ground surface below the steer assembly and move the at least one leg member when the steer assembly is moved across the ground surface. The steer apparatus may also comprise a rope deflection assembly configured to deflect a rope from looping about the at least one leg member for at least a forward portion of the arc of movement of the leg lower end.

Abstract: A retrievable anchor system may comprise an anchor having a central shank with a top and bottom end, an elongate flexible member having a base end substantially permanently fixed to the bottom end of the central shank. The system may further comprise a dual attachment assembly releasably attaching a location on the flexible member to a location on the central shank located toward the top of the anchor, with the location on the flexible member being separated from the base end of the member. The dual attachment assembly may comprise a primary attachment structure forming a directional attachment between the flexible member and the central shank, and a secondary attachment structure forming a frangible attachment of the flexible member to the central shank.

Abstract: A mechanical roping steer apparatus for practicing roping of a steer is disclosed that comprises a support assembly for engaging the ground surface and a steer assembly mounted on the support assembly. The support assembly may comprise a main frame and a pair of lateral skids mounted on the main frame, and the pair of lateral skids may each be pivotable with respect to the main frame. In some embodiments, the steer assembly includes a frame and a body covering assembly mounted on the frame and configured to move with respect to the frame in response to movement of the steer assembly across the ground surface. In some embodiments, the steer assembly comprises includes a frame and a head assembly mounted on the frame and configured to move with respect to the frame in response to movement of the steer assembly across the ground surface.

Abstract: A mechanical roping steer apparatus with enhanced stride simulation includes a forward support assembly for resting on a ground surface. The support assembly has a front and a rear. A rearward steer assembly is located rearwardly of the support assembly and is mounted on the rear of the support assembly. The steer assembly comprises a leg assembly including a pair of leg members being pivotable with respect to the ground surface and an actuation mechanism for pivoting the leg members when the support assembly is moved across the ground surface.
