The 1839 uniform regulations specified a shoulder belt (rather than a waist belt) for carrying the sword, with a "breast plate according to the pattern to be furnished by the Ordnance Department." This plate, which was worn by Capt. Erastus Capron, 1st Artillery, an 1833 graduate of the Military Academy, is believed to be that specified.[95] The specimen is rectangular with beveled edges, cast in brass, and has the lines of a modified sunburst radiating outward. In the center, within a wreath of laurel, are the letters "U S" in Old English. Both the wreath and letters are of silvered copper and are applied. The plate is attached by three broad hooks rather than two studs and a hook.

This plate is almost identical to the Capron specimen above except that the letters "U S," instead of being in Old English, are formed of oak leaves.

The 1839 uniform regulations prescribed this plate for the Corps of Topographical Engineers. The oval inner plate, which contains the prescribed eagle, shield, and the letters "U S" in Old English, is struck in medium weight copper and gilded. This inner plate is soldered to a cast-bronze and gilded tongue which in turn is brazed to a cast-bronze belt attachment. The oval outer ring, bearing the prescribed "CORPS OF TOPOGRAPHICAL ENGINEERS" in Roman capitals, is cast in brass and gilded. To the inner edge of this outer ring are brazed two curved seats for the inner oval. The whole is brazed to the belt attachment, also cast in brass and gilded.
