Edmund Rice earned distinction as the inventor of several military accouterments
including; Rice's Trowel Bayonet, Rice's Stacking Swivel for rifles and
carbines, Rice's Knife Intrenching Bayonet and Rice's ImprovedBlanket Roll
and Shelter Half Tent.
Rice's first military invention was a combination bayonet and hand shovel or trowel used to dig quick field intrenchments and throw up works or cover in a hasty defensive situation. The Rice Trowel Bayonet also could be placed on the end of the Springfield Rifle and used as a formidable weapon. The first of several versions was the Model 1868 Rice Trowel Bayonet of which only five hundred were produced.
In June of 1868 Rice was assigned to the Springfield Armory to supervise the manufacture of the Model 1868 for trial by the U.S. Army. While stationed there his daughter Corinne Miles Rice was born to he and his young wife, Annie Dutch Clark Rice. General Nelson A. Miles was the godfather of baby Corinne. Annie tragically died only six months after her daughter was born, of tuberculosis at the tender age of twenty years.
