Albert Charbonneau of Boston, Massachusetts celebrated Bastille Day in 1931
with a new patent issued on July 14 (Bastille Day). He was granted United States
Patent Number 1,814,895 for his
“
Compound
Appliance.
”
To get his patent Charbonneau simply
added a corkscrew to Maurice Robert
‟
s 1926 patent for
a
“
Bottle Stopper.
”
Charbonneau says he wanted to make Robert
‟
s
invention more useful by
“
utilizing certain of the
essential portions of the patented construction for the
purpose of attaching and housing an added
instrumentality, preferably a corkscrew.
”
The new tool
will lift a bottle cap and reseal the bottle or pull a cork
from a bottle.
Like Maurice
‟
s patent, this patent was assigned to the Roberts Specialty
Manufacturing Company of Boston. It was produced using the same stamping as
on the original cap lifter/sealers:
“
Sav-Kap, Pat. Dec. 7, 1926, Boston.
”
Robert
‟
s 1926 Patent
