  • the illustrated razor comprises a guard member 10 ⁇ having a flat, bladesupporting surface bounded by spaced parallel shoulders 14 over which the blade is flexed by the cap.
  • the longitudinal edges of the guard are provided with guard teeth 12.0f usual construction.
  • the blade-receiving face of the guard is provided with a pair of spaced blade-locating projections 16,- herein shown as beingV diamond-shaped in outline.
  • the guard 10 1s rigidly secured to or made integral with a forked head 18 which, with the barrel 20 constitutes the handle of the razor.
  • An elongated guide member 22 is movably mounted in the space between the forks of the head 18 beneath the blade-engaging face of the guard 10.
  • a guide track 24 is formed in the upper face of the guide member 22 and extends longitudinally from one end thereof to the other, and this track has undercut flanges extending along its opposite longitudinal edges for the reception of a slide which will be presently described.
  • the guide member 22 is held against longitudinal movement and prevented from being dis placed endwise in the forked head 18 by a spindle 30 which is housed within the barrel 20 of the handle and passes upwardly through a bore in the head 18. At its upper end, it is riveted into the bottom of the guide member 22.
  • the spindle 30 is threaded at its lower end to receive a knurled nut 32 and this is retained in place by an annular flange upon the lower end of the barrel 2O which enters a circular groove in the ⁇ body of the nut.
  • the guide member 22 is provided at its lefthand end, as seen in Figs. 3 and 6, with an upstanding ear 26 which terminates in an overhan ing lip 28. At its other end, it is provide with a pair of stop pins 25 which project into the guide track 24 at its rightland end, as shown in Figs. 6 and 8. At the same end, the guide member 22 is provided with a square notch opening through the bottom face thereof.
  • the cap comprises an elongated member 34 having a concave blade-shaping face with parallel, longitudinal edges which co-operate with the shoulders 14 of the guard in maintaining the flexible blade in a position of pronounced transverse curvature when the parts are positioned in shaving relation.
  • lade-shaping member of the cap is connected through a neck 36 at its outer end with a slide member 38, having, at either edge, laterally-projecting flanges 39 which fit in the undercut ways of the track 24 of the guide member 22.
  • the flan .es 39 terminate somewhat short of the leftE-qhand end of the slide 38 and a cross pin 37 is provided therein at its extreme end and this extends from wall to wall of the track 24 and limits the endwise blade-exposing movement of the cap by encountering the stop pins 25, as indicated in Fig. 8.
  • the cap is guided in a rectilinear path so long as the flanges 39 of its slide are moving within the track 24, but when the cap member has been displaced endwise to the limit of its blade-exposing movement, the end of the slide 38 is positioned over the notch in the end of the guide member 22 so that the cap member is free to swing from the position shown in Fig. 8 to the inoperative position shown in Fig. 6. Since angular displacement of the cap is positively prevented until it has been moved to the limit of its blade-exposingmovement, all possibility is avoided of the captouching the blade and displacing it or dulling its shaving edge.
  • the cap member 34 is provided at its lefthand end, as shown in Figs. 3 and 7, with a recess forming a lip 40 which is arranged to interlock with the overhanging lip 28 of the guide member when the cap is moved fully into superposed position above the guard 10.
  • the slide member 38 of the cap is provided with a vertical hole 42 and this is arranged to be brought into alignment with a stationary pin 44 set in the forked head 18 and projecting upwardly into the throat thereof.
  • the pin 44 constitutes a locking device for positively holding the cap member against displacement when the latter has been moved ⁇ into blade-engaging position and drawn down toward blade-flexing position.
  • the upper end of the locking pin 44 clears i the lower face of the slide 38 by a slight amount only so that, as soon as the head 32 is turned to lower the guide member 22, the pin 44 will immediately enter the hole 42 D is and loc'kthe cap and guard members positive-y ly in alignmengwhile, at the same time, permitting lthem tobe moved relatively toward andfromeach other ⁇ to flea the blade and to, regulate the degree of flexing andfconslequently the amount of edge exposure of the blade with respect to tlie'gua'rd.
