Frank English Pat. No. 1,653,995
Frank English Pat. No. 1,758,504
On December 27, 1927 Frank English of Detroit, Michigan was granted U. S. Patent No.
1,653,995 for his
Flexible Handled Tool
. Noting that the entry to the stuffing box is
generally at an angle, English incorporates a flexible shaft. He also uses interchangeable
heads and writes
...the
corkscrew
(20) may be removed from the head (13) and the
screw driver (21), which is provided with a head (18), threaded into the recess (14).
English's second patent was issued May 13, 1930. In this patent he writes
The outer
end of the shank (18) is formed into a suitable tool (19), in the present case being a
cork
screw
.
He had applied for both patents in 1925.
In Ervin Webb's 1932 patent we see a drawing of
the tool in use. In his application he writes
...
one end is bent to form a finger ring or grip and
the other end is bent in the form of a
cork screw
...
U. S. Patent No. 1,858,176 was granted to the
Beaumont, Texas resident on May 10, 1932.
