US Patent:

Filed:
Mar 2, 1978
Appl. No.:
5/882651
Inventors:
Kenneth E. Nickle - Kearns UT
International Classification:
B26D 8524, B25B 2304
US Classification:
144 32R
Abstract:
A power screwdriver for use with a flexible string of disconnected screws retained in head to tip orientation by attachment to a continuous length of plastic, paper or similar flexible material. The string of screws feeds into a rearward section of a reciprocating shaft of the power screwdriver where the screws are individually advanced into alignment with an engaging bit, the combination bit and shaft being continuously rotated during the course of use. As the forward screw is prepared for engagement by the rotating bit, the retaining plastic or similar material is severed, leaving the forward screw free for emplacement. The screw is engaged and advanced to a forward opening of the shaft by thrust pressure applied by the user to reciprocate the shaft rearward with respect to a power train which is keyed to continuously rotate the shaft and bit. When the thrust pressure is withdrawn, a spring compressed by the rearward motion of the shaft returns the shaft forward to a stable position. In conjunction with this motion, a dog mounted within the shaft catches the head of a lead screw and carries it forward for engagement by the bit.
