9301. Simms, H. H. April 17, 1909, [Convention date]. Razors, safety. In a razor, of the type in which the blade is secured between a pair of plates and gripped adjacent to its cutting- edges, the blade-holder co-operates with a separate guard, and the holder and guard are relatively movable or completely separable to permit the cleaning and stropping of the blade while in the holder. In the form shown in Figs. 1 and 3, the lower plate 8 of the bladeholder is, in the shaving position, disposed in a recess in the guard plate 2, which has guideslots with which extensions 3 on the plate 8 engage; tongues 5 on the extensions 3 secure the blade - holder in the shaving position. For stropping and cleaning, the holder is held away from the guard by tongues 6 on the extensions 3, lugs 7 limiting the upward movement of the extensions. The handle consists of a sleeve 15 on a stem 14, which in the shaving position, Fig. 1, screws into a boss 13 on the guard, the sleeve being prevented from rotating by a notch 7 therein which engages with a projection 16 on the boss 13; for stropping, the stem 14 screws into a lug 18 on the guard, the sleeve being free to rotate as the razor is reciprocated along the strop 20. The plates 8, 9 of the blade-holder are held together with the blade between them by a screw 10. In a modification, the lower plate of the blade-holder is hinged to the guard which has a pair of spring latches, of which one holds the blade-holder in the shaving position in a recess in the guard, and the other holds the bladeholder in the stropping position at right-angles to the guard and parallel with the handle. The handle consists of a central stem and an inner and outer sleeve, the inner sleeve being fixed to the guard, and the outer sleeve being adapted to be secured against rotation on the inner sleeve or allowed to rotate thereon according as to whether the blade is being used for shaving or is being stropped. The stem is rotatable within the inner sleeve and carries a projection which engages with a slot in the head of a screw journaled in the lower plate of the holder and engaging with the upper plate; by rotating the stem, the plates are clamped or separated. In a further form, the holder plates are hinged together and secured by a spring latch, the guard being entirely separated from the holder for stropping, but secured thereto for shaving by a projection and spring latch which engage slots in the holder. The handle can be secured to an extension of the lower plate either parallel with or at right-angles to the blade-holder. In another form in which the holder-plates are hinged together as described above, the handle is fixed at right-angles to the blade-holder and the guard is carried by a screwed stem which engages with a nut journaled in the boss to which the handle is fixed. By rotating the nut, the guard can be held at various distances from the blade edges, the stem passing within the hollow handle; the guard has end lugs by which it is guided on an extension of the blade-holder.
