  • Patent number: 5895004
    Abstract: An apparatus for winding wire onto a magnetic ring structure defining slots for receiving wire coils formed thereon. The apparatus includes a mounting structure for holding the ring structure and a platform supported within the peripheral area defined by the ring structure, the platform supporting a wire feed mechanism and a wire forming mechanism. A guide member is supported on an end of the platform adjacent to the ring structure and includes a face plate which is spring biased into engagement with the ring structure to thereby prevent wire from slipping out of the slots in the ring structure as the coils are wound. The guide member, along with the platform carrying the wire feed mechanism and wire forming mechanism, is mounted for rotational movement about a rotational axis, and is further supported for movement in horizontal and vertical directions, perpendicular and parallel to the rotational axis, respectively.

  • Patent number: 4436235
    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.
