U. S. Patent No. D180,316
On February 18, 1958 Harvey A. Brownson of Baltimore, Maryland was granted U. S. Patent Number 2,823,395 for his Combined Seal Cutter and Closure Removing Device. Brownson wrote "It is one of the objects of this invention to provide a unique cutter-remover device for cutting a seal on a bottle and for simultaneously removing the bottle cap or cork."
No examples of the patent 2,823,395 have been reported by corkscrew collectors. Brownson had applied for his patent on September 14, 1956. On the same date, he filed for a design patent on a similar device without the folding worm. For this he was granted U. S. Design Patent D180,316 on May 21, 1957; nine months before the utility patent. The title for this one is Combined Seal Cutter and Bottle Cap Remover.
