"Hump?" you ask…
In 1926 Everett Irving Rogers Jr. was granted a design patent (D69235) for an opener with a camel’s head/mouth as the opener. It should be said, that the patent drawings did NOT include a hump…on the other hand, the patent drawings did not call for a corkscrew either. However, there are a few of these openers that were produced that DO have a corkscrew.
And, while the patent drawings do not include the corkscrew, it is clear that the humpless camel (poor camel) is definitely enhanced with an appropriate helix attached.
In the patent description, a hump isn’t mentioned, nor is a camel, or a corkscrew for that matter. It simply states, "Be it know that I, Everett Irving Rogers Jr., a citizen of the United States, residing at Providence, of the county of Providence and State of Rhodes Island, have invented a certain new, original, and ornamental Design for a Bottle Opener, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.
Fig. 1 is a plan view of the bottle opener, showing my new design.
Fig. 2 is a side elevation of a bottle opener showing my new design.
The ornamental design for a bottle opener, substantially shown.
In testimony whereof I affix my signature.

A welcome addition to the humpless camel corkscrew collection!!!
