“ Without a guide, the difficulty should not be very great of aligning projections and recesses distant from each other but a fraction of an inch when the edges of the cap and sleeve are in contact. The constructions held by the Circuit Court of Appeals of the Second Circuit to infringe the patent in suit, were so essentially different from that of the respondent that we regard discussion of them as quite unnecessary. ”

“ The petitioner cannot read into the patent in suit the additional slot in the cap and the additional projection on the sleeve of patentee's second patent, and without them there is no lock against rotative movement in the socket of the first patent to be infringed by the stud snapping into the locking hole of the sleeve of respondent's socket. ”

“ Instead of slits and outwardly extending recesses in the cap of the one there are inwardly extended studs riveted to the cap of the other. And instead of slits and outward protections of the sleeve to lock by snap action with recesses in the cap against longitudinal movement in the one, there are the bayonet slots in the sleeve to lock with studs in the cap of the other to accomplish the same result without snap action. ”
