Other Notes: A contemporary of Pauly (q.v.), Robert embraced Pauly's idea for a self contained cartridge and 'improved' it by replacing the exposed fulminate central primer of the Pauly design with a flat extended folded copper 'tab' of fulminate that was mounted perpendicular to the cartridge base. Internal hammers struck these tabs against anvils within the action, firing the charge. Unfortunately the design was not a great success as corrosion problems soon arose and this together with the ease of accidentally detonating the cartridges when being transported in a bag or pocket lead to many accidents and correspondingly low volumes of sales
