Today in 1937, US Patent 2090714 A was issued, an invention of Raymond H. Frisbie and William Wright, for their “Bottle Opener.” There’s no Abstract, although in the description it includes this summary:

This invention appertains to a novel appliance for removing crown caps from bottles in a convenient and expeditious manner.

One of the primary objects of our invention 5 is the provision of a bottle opener of the wall type, embodying means whereby the caps can be quickly and firmly gripped for removal without the necessity of lifting the bottle above the horizontal, so that undue disturbance of the bottle contents will be prevented.

Another salient object of our invention is to provide a wall bottle opener having a swinging member provided with a cap-engaging lip, and means for guiding the cap under said lip when the bottle is pushed forwardly (in a substantially horizontal plane) in the opening. with means for limiting the swinging movement of said member so that upon downward movement of the bottle the lip will function to pull the cap from the bottle neck.

A further object of our invention is the provision of a wall bottle opener embodying a supporting plate for carrying the swinging member and for supporting a receptacle for the loose caps, the swinging member functioning to guide and throw the caps into the receptacle when the same are pulled off of the bottles.

A further important object of our invention is the provision of a cap stop on the swinging member arranged below the cap-engaging lip, so that the bottle neck and cap will be held in proper position when the bottle is inserted in the opener, and when the member is swung to its operative cap-engaging position.
