Several caliper accessories are provided that make a conventional caliper suitable for more sophisticated applications traditionally reserved for more expensive measurement devices. One of these accessories, a magnetic caliper mounting device, has a shallow scale-bar-mounting channel for receiving the scale bar of the caliper, a retainer adapted to releasably secure the scale bar of the caliper within the channel of the caliper mount, and a magnet associated with the caliper mount to secure the apparatus to a planar metal surface. Another accessory, a caliper jaw extender, is either incorporated into a magnetic caliper mounting device or provided as a spring pack accessory to a magnetic caliper mounting device. The caliper jaw extender has a spring-biased retractor that hooks onto a caliper's movable frame and biases the frame toward an extended position. Kits are also provided comprising various combinations of a conventional caliper and accessories.

I claim: 1. An apparatus for mounting a sliding caliper near a planar metal surface, the apparatus adapted to be secured to the planar metal surface without a clamp or a screw, the apparatus comprising: a caliper mount adapted for mounting a sliding caliper, wherein the caliper has a fixed jaw attached to a scale bar, a movable frame and movable jaw mounted for sliding along the scale bar, and a depth probe mounted within a slot of the scale bar; the caliper mount having a shallow channel for receiving the scale bar of the caliper, the channel having a width of approximately five-eighths of an inch and extending longitudinally between opposite edges of the caliper mount; a retainer adapted to releasably secure the scale bar of the caliper within the channel of the caliper mount; and a magnet associated with the caliper mount and having a flat exposed surface operable to secure the apparatus to a planar metal surface. 2. The apparatus of claim 1, further comprising a tapered jaw mounting channel for receiving the movable jaw of a sliding caliper. 3. The apparatus of claim 1, further comprising a groove positioned down the middle of the shallow channel of the caliper mount, and extending longitudinally along the length of said channel, the groove facilitating unhindered movement of the depth probe of a caliper mounted on the caliper mount. 4. The apparatus of claim 1, further comprising a curved recess positioned down the middle of the shallow channel of the caliper mount, and extending longitudinally along the length of said channel, the groove facilitating unhindered movement of the depth probe of a caliper mounted on the caliper mount. 5. The apparatus of claim 1, wherein the retainer comprises a thumb screw that is mounted vertically with respect to the channel of the caliper mount. 6. The apparatus of claim 5, further comprising a washer mounted on a shaft of the thumb screw, the washer adapted to press against a top surface of the scale bar of the caliper, thereby securing the caliper within the channel of the caliper mount. 7. The apparatus of claim 1, wherein the retainer comprises a thumb screw that is mounted horizontally with respect to the caliper mount, the thumb screw being operable to press against a flexible wall of the channel of the caliper mount to cause the flexible wall to press against a side of the scale bar of the caliper. 8. The apparatus of claim 1, wherein the retainer comprises a thumb screw that is mounted horizontally with respect to the caliper mount, the thumb screw having a plastic tip that is operable to protrude through a channel wall of the caliper mount and press against a side of the scale bar of the caliper. 9. The apparatus of claim 1, wherein the retainer comprises a cam mounted to a side of the channel of the caliper mount, the cam being operable to rotate about an axis between a caliper release position and a caliper retaining position. 10. The apparatus of claim 1, wherein the channel is oriented to hold a caliper so that its longitudinal axis is parallel to a planar metal surface to which the apparatus is mounted. 11. The apparatus of claim 1, wherein the channel is oriented to hold a caliper so that its longitudinal axis is perpendicular to a planar metal surface to which the apparatus is mounted. 12. The apparatus of claim 1, wherein the caliper mount comprises a housing for the magnet, a caliper holder containing the channel for receiving the scale bar of the caliper, and a joint that rotatably attaches the caliper holder to the caliper mount, the joint enabling the caliper to rotatably oriented with respect to a planar metal surface to which the apparatus is mounted. 13. The apparatus of claim 1, wherein the caliper mount comprises a housing for the magnet, a caliper holder containing the channel for receiving the scale bar of the caliper, and a joint that attaches the caliper holder to the caliper mount, the joint being operable to position the caliper at any angle with respect to the planar metal surface to which the apparatus is mounted. 14. The apparatus of claim 1, further comprising: a caliper jaw extender associated with the caliper mount, the caliper jaw extender having a spring-loaded retractor, a retractor connector adapted for connection to the movable frame of the caliper, and a spring with sufficient tension to pull the caliper's movable frame, if unobstructed and connected to the retractor, toward an extended position. 15. The apparatus of claim 14, wherein the caliper jaw extender and caliper mount share a common housing. 16. The apparatus of claim 15, wherein the spring and retractor are part of a spring pack accessory that is physically independent of the caliper mount, the spring pack accessory having a base connector adapted to mount the spring pack accessory on the caliper mount. 17. The apparatus of claim 1, wherein the channel for receiving the scale bar of the caliper has a length of at least approximately one inch. 18. The apparatus of claim 1, wherein the apparatus consists of a single, structurally-integrated unit of hardware with a single mounting surface area for securing the apparatus to a planar metal surface. 19. An apparatus for mounting a sliding caliper comprising: a caliper mount adapted for mounting a sliding caliper, wherein the caliper has a fixed jaw attached to a scale bar and a movable frame and movable jaw mounted for sliding along the scale bar; the caliper mount having a shallow channel for receiving the scale bar of the caliper, the channel having a width of approximately five-eighths of an inch and extending longitudinally between opposite edges of the caliper mount; a retainer adapted to releasably secure the scale bar of the caliper within the channel of the caliper mount; and a caliper jaw extender associated with the caliper mount, the caliper jaw extender having a spring-loaded retractor, a retractor connector adapted for connection to the movable frame of the caliper, and a spring with sufficient tension to pull the caliper's movable frame, if unobstructed and connected to the retractor, toward an extended position. 20. A caliper kit comprising: a sliding caliper having a fixed jaw attached to a scale bar and a movable jaw mounted for sliding along the scale bar; a caliper mount adapted for securing the sliding caliper to a machine for working metal, wood, or plastic; the caliper mount having a shallow channel for receiving the scale bar of the caliper, the channel having a width of approximately five-eighths of an inch and extending longitudinally between opposite edges of the caliper mount; a retainer adapted to releasably secure the scale bar of the caliper within the channel of the caliper mount; and a spring pack accessory having a spring-loaded retractor, a retractor connector adapted for connection to the movable frame of the caliper, and a spring with sufficient tension to pull the caliper's movable frame, if unobstructed and connected to the retractor, toward an extended position. 21. A caliper kit comprising: a sliding caliper having a fixed jaw attached to a scale bar and a movable jaw mounted for sliding along the scale bar; a caliper mount adapted for securing the sliding caliper to a machine for working metal, wood, or plastic; the caliper mount having a shallow channel for receiving the scale bar of the caliper, the channel having a width of approximately five-eighths of an inch and extending longitudinally between opposite edges of the caliper mount; and a retainer adapted to releasably secure the scale bar of the caliper within the channel of the caliper mount; wherein the caliper mount further comprises an integral caliper jaw extender having a spring-loaded retractor, a retractor connector adapted for connection to the movable frame of the caliper, and a spring with sufficient tension to pull the caliper's movable frame, if unobstructed and connected to the retractor, toward an extended position.
