1. 1860 Philos Blake patent #27,665 with floating “lever nut,” using the language from the patent description, that, “…bears directly against the cap…and is entirely separate therefrom…” marked MARCH 27-60 (O’Leary, p. 32-33).

2. 1867 Abraham T. Russel patent #34,216.  Marked faintly on the cam with PAT, but the rest of the marking too faint to read (O’Leary, p. 33).

3. 1860 Philos Blake patent #27,665 with fixed “lever nut,” that “revolves within and is connected to the cap,” marked MARCH 27-60 (O’Leary, p. 32-33).

4. 1893 Jeremiah Matthews patent #496,887 for a Door Securer, with peg and worm type corkscrew.  Marked across the handle COLUMBIAN, PAT. APL’D. FOR, and MATTHEWS SOUTH BEND, IND., and on the door securer / peg PAT. NOV. 1, 92.  This is Matthews' 1892 door securer patent combined with his 1893 patent where the case and corkscrew were added.  As explained in the most recent issue of The Bottle Scrue Times and at our ZOOM 2020 AGM Show & Tell, this is a new discovery from the back of O'Leary (O’Leary, p. 208).

6. 1875 Frank R. Woodard patent #166,954 in plier form, unmarked (O’Leary, p. 39).
