WORLEY, Chief Judge
(dissenting in part).
I find no reversible error in the decision of the board that claim 25 is “so broadly drawn as to be fairly rejected” on the wing nut locking means of Knerr. While the majority correctly states with respect to claim 21 that “there is no need to resort to the specification to ascertain what invention is defined by the claim,” yet the majority appears, inexplicably, to do just that with respect to claim 25, the language of which is markedly similar to that employed in claim 21. It is, of course, well settled that limitations in the specification not appearing in the claims may not be relied upon to impart patentability to those claims. See In re Margaroli, 318 F.2d 348, 50 CCPA 1400; In re Edwards, 285 F.2d 811, 48 CCPA 808; In re Lundberg, 244 F.2d 543, 44 CCPA 909. Although Knerr may not show appellant’s disclosed locking means, there can be no doubt that he shows the claimed locking means.1 I would affirm the board’s decision in its entirety.

. I agree with the solicitor that:
As shown in * * * Knerr * * *, the wing nuts * * * appear to have lopsided wings or handles rotatable * * * [in a plane] parallel to the longitudinal axis of the airplane. This means that the associated studs or bolts are transverse to that axis. Hence, when the bolts are inserted in [the] nuts * * * and the latter threaded up, there will be mutual pull to restraint laterally of the airplane. ♦ * *
