PETERS, District Judge.
This is a suit charging infringement of Letters Patent 2,130,968, issued to the plaintiff September 20, 1938, upon an application filed January 3, 1938.
The defendant admits infringement but attacks the validity of the patent, contending that the claims are anticipated by the prior art and that the improvements claimed, if novel in any particular, are the result of mechanical skill and in no degree the result of inventive genius.
