Abstract: 221,916. Hiorns, A. E. E. July 20, 1923. Razors.-A combined safety razor and stropping-appliance comprises a razor with a. singleedged blade capable of being held rigidly in either the shaving or stropping position and a base or casing with means for supporting the razor therein and for automatically bringing the blade into contact alternately with a pair of stropping rollers to which a to and fro rotary movement is imparted by a reciprocating handle slidable in the base or casing. As shown in Figs. 1 and 2 the stropping rollers 12 are rotatably mounted on a base 14 and are rotated to and fro by the handle 24 slidable in a slot in an upright side 26 on the base and connected to a flexible drive 23 passing around the rollers and an oscillatory carrier 13 journaled on the base. The carrier has a table 20 for supporting the, handle 1 of the razor, Fig. 4, a slot 2 in the handle being engaged by a member 3 slidable in a standard 21 on the table and connected at its lower end 17 to a spring 22 also connected to the carrier 13; the end 17 of the member 3 co-operates with a slotted abutment 16 fixed on the base. The blade 6 is held in a carrier 8 pivoted in a. frame 7 which with the guard 5 are held in slots in the handle 1, a clip 10 slidable on the frame 7 and engaging the guard holds the parts in the shaving position, Fig. 4, or, when slid towards the handle, allows the blade to be turned into line with the handle; in this position the blade is secured by sliding the clip to engage a tongue 9 on the blade holder. The razor with the blade in line with the handle is engaged by the member 3 when a pivoted part 3* thereof is in the vertical position; on turning the part 3* to the horizontal position, the razor is secured on the table 20 and a slot in the end 17 of the member 3 comes into alignment with the slot in the abutment 16 so that the carrier is free to oscillate between ears on the abutment to bring the blade against the rollers 12 alternately when the handle 24 is operated. In a modification the razor has a pivoted guard 44, Fig. 11, which can be folded against the frame and the blade-holder 43 has slots engaging pinions 48 on a spindle 43* journaled in the frame; by rotating the spindle the blade-holder can be turned to secure the blade in the shaving position or in the stropping position; in the latter position a projection on the holder engages a notch 52 in the frame and holds the blade at right angles to' the handle which has a hole adapted to engage a pivot pin 35, Fig. 7, on the case of the stropping-apparatus. The case 28 of the stropping-apparatus contains a frame 29 in one end of which is journaled a pair of stropping rollers 30, 30*, the razor being supported on cross bearers 40 carried by the case with the blade between the rollers which are geared together and rotated by a flexible drive 32 operated by the reciprocating handle of the apparatus; the frame 29 is vibrated to carry the rollers 30, 30* alternately into engagement with the blade by frictional engagement of the reciprocating handle with the frame. A second pair of stropping- rollers 31, 31* may be joumaled at the other end of the frame so that coarse and fine stropping may be obtained. A spring normally holds the frame in its central position with the blade out of contact with the rollers but when the lid of the case is closed to clamp the blade on the cross-bearers, the spring is released to allow the frame to be vibrated.
