Interference No. 104,158 portion 3 which contains an arcuate wall portion 6. In this arcuate wall portion is mounted a generally C-shaped yoke member 10. The free ends of the yoke portion carry pivot pins 11 for mounting the lugs of the blade-containing head. Page 2, lines 1-5. Thus, the head 1, when mounted on the pivot pins 11 can rock about an axis. The rocking axis, located at XX in Figures 1 and 2 of Kirk, is substantially parallel with the tangent plane T and transverse to the length of the head. Id. at 16-19. The two axes XX and YY may intersect or be slightly offset, but both are preferably close to the blade edge in order to provide maximum conformance to the skin surface during shaving. Id. at 37-40. From the orthogonal view in Figure 2, it is difficult to determine the exact spatial relationship of axes XX and YY in this embodiment. Certainly any attempt to locate the center of rotation of the C-shaped yoke member 10 is highly 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
