More about the 6 pdr. Wiard Rifle
Norman Wiard, a Canadian working for the United States invented several light artillery pieces which, although apparently excellent weapons, do not seem to have been very popular. Wiard described his weapons as being made of semi-steel in two calibers: a 6-pdr Rifle with a 2.6 inch bore and a 12-pdr smoothbore with a 4.62 inch bore.
Wiard designed a unique carraige for his pieces. The first unusual feature was the axle and cheek arrangement which was designed for strength and high angle of barrel elevation, as high as 35 degrees. This arrangement also permitted tighter storage and transportation because one carraige could slide beneath the next. Another innovation was the flat trail plate with a metal keel to guarantee that upon recoil the trail would slide straight and not dig in to soft dirt. Wiard also devised a better system for braking a gun carriage using a steel skid that held the carraige wheel from turning without damaging the iron tires.
