Abstract
My invention is directed to portable pneumatic nail driving devices for working with large nails ranging in size from 30 to 90 penny which are fed from a primary chute through a transfer chute to a nail driving barrel carried by a base frame. Upstanding from the base are guides over which slides a cradle to which a pneumatic gun having a chisel is carried to that the chisel enters the barrel after a nail has been introduced to drive the nail. Such apparatus is used in the construction of board roads in swamps incident to oil field work.
