Provided in the upper end of with a head of another form from the preferred the handle I5, at its junction with the head I3 form. -isv an enlarged upwardly opening recess 4l, and 5 Referring to thedrawing Iiindicates the hanextending downwardly from the bottom wall of die. the upper end of which terminates in the this recess, concentric therewith, is a smaller rehead I6, preferably extending at right angles cess 42. Rotatably mounted within the recess 42 thereto, and centrally of its length. Extending is a stem 43 on the upper end of which is ahead upwardly from the longitudinal edges of the head 44 mounted within the recess 4I, and extending u upwardly from the upper face of head 44, at one side thereof, is a pin 45. Pin 45 extends into a slot 46 provided in the front face or edge of the blade carrying block or reciprocating head 23, so that as the head 44 and stem 43 are reciprocated .around their vertical axis head 23 will be caused to reciprocate in a horizontal plane or at right angles to the reciprocation of said stem and head. Formed in the opposite end of the handle l5 is an elongatedconcentric chamber 41, in the upper end of which is slidably mounted the manually reciprocated operating. member which consists of a tubular body member lengthwise of said chamber 41 and provided with a central opening 49 therethrough. Provided through the side wall of the handle l5 near the upper end ofthe chamber 41 is a slot 50, and projecting through this slot is 4an abutment 5|,

the inner edge of which bears against the outer4 face of the lbody member 48 and the outer edge of which bears' against the inner. face of' the, thumb or finger member 52, a screw 53 serving to detachably hold said. members assembled for use. Abutment 5l isof a thickness slightly greater than theA thickness of the wall lof the handle `I 5 .and is suiiiciently less in length than the .slot 50 to permit the full downward movement of .the body member 48 as hereafter described. s y v Y Connecting the lower end of the recess 42 to the upperend of the chamber 41 is a passage 54 and rotatably mounted in this passage is the rotator or reciprocator 55. The upper end of this rotator is rigidly connected tothe stem 43 and head 44 so that they all irotate or. reciprocate in unison and the lower endof said reciprocator is twisted or otherwise formed intcil a helix 51. The

upper end of the opening 49 in body member 48 is reduced in vrsize and is provided with an interior helix 58 adapted for vcooperation with the helix 51 whereby when said body me k ber 48 is recipro- .cated vertically the r v'tator 55v will be rotated or reciprocated horizontally. AAn integral collar 59 surrounds rotator 5 5 immediately above the helix 51 and bears against the upper end of the wall of chamber 41. The lower end of thechamber 41 is closed by means of a screw-threaded plug 60.

Positioned within'the lower end of the chamber 41, between the upper end of the plug 60 and the lower end of the body member 48, is a coil spring 6I thefunction of which is to normally hold member'48 in its uppermost position.

In the operation of my razor,I the same is drawn along the surface by means of the handle in a similarmanner` tothe usual procedure with the f ordinary safety razor, and at the same time,`by

-means of the thumb or finger, the thu'rrib or finger .piece 52'is moved downwardly causing the reciprocating head tofmovey at a right angle or 48, mounted to slide` diagonally to the direction of movement of the handle.

Having described my invention what I claim is: 1. In a safety razor, the combination of a hollow handle having a removable closure for the lower end thereof and a transversely extending head on the upper end thereof and longitudinally extending guideways in the upper face of said head, a blade carrying block slidably mounted in said guideways and havingblade securing means, and means mounted within said handle for manually causing said blade carrying block to slide in said guideways, said means comprising a disc rotatably mounted in the upper end of said handle, an eccentrieally mounted pin projecting from the upper face of said disc, a transverse slot in said blade carrying block vinto which said pin projects, a rectangular stem rigidly secured at its upper end to said disc and extending axially therefrom concentrically of the handle, the lower portion of said stem being twisted axially to form ya spiral, a sleeve slidably but non-rotatably mounted in said handle havinga passage therethrough, said passage being of a configuration to coincide with-the configuration `of said stem whereby relative lengthwise movement of said sleeve and stemv will ycause said stem to rotate, a iinger piece slidably mounted against the outer wall of'said handle and connected to said sleeve for moving said sleeve lengthwise of the handle, and a coil spring mounted in said'handle between the bottom end of said sleeve and the lower end of said handle adapted to maintain said sleeve in its yuppermost position.

2v. In a safety'razor having a transversely movable blade carrying means, means for moving said blade carrying means including a supporting handle, said handle being hollow, a disc rotatably mounted in the upper end of said handle concentrically thereof and having a concentric vintegral sleeve depending downwardly from the lower face thereof and a rectangular stem depending downwardlyfrom said sleeve, the projecting portion of said stem being twisted axially to form an external spiral, a longitudinally extending slot through the side wall of said handle, a sleeve slidably mounted in said handle and having a spiralled passage therethrough for the reception of the spiralled stem whereby lengthwise movement of )saidN sleeve will rotate said stem, said sleeve having a finger piece projecting through saidfslot'for manual reciprocation of the samev and to limit the vertical movement thereof, said ngerpiece terminating in a head at the outer wall ofthe handle, arranged to inclose the slot in the handle, and a coil spring in the lower end of the handle arranged to yieldably retain vsaid sleeve in its uppermost position;
