this may be accomplished readily by simply retracting or otherwise removing the pin 10 and detaching Athe knob. Thereupon, the various parts may be withdrawn. In lieu of the ring l5 as shown in Fig. 1, the tube as in Fig. 2 may be extended as at 22 to provide a structure whereby entrance of soap is prevented.

Thus, among others, the several objects of the invention as specifically aforenoted are achieved. It will be appreciated that numerous changes in construction and rearrangement of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent is:

l. A razor, comprising a stem, a knob secured thereto, a tube enclosing said stem, a sleeve associated with said tube, a guard secured to said tube, a clamping plate secured to said stem, means for retaining said sleeve in position with respect to said tube, and means whereby said clamping plate is caused to shift axially and rotatably with respect to said guard to permit of a blade being dismounted from the latter.r

2. A razor, comprising a stem, a knob secured thereto, a tube enclosing said stem, a sleeve associated with said tube, a guard secured to said tube, a clamping plate secured to said stem, means for retaining said sleeve in position with respect to said tube, said sleeve being rotatable with respect to said tube and knob, and means functioning automatically upon such relative rotation occurring to shift said clamping plate axially and rotatably away from and towards said guard.

3. A razor, comprising a stem, a knob secured thereto, a tube enclosing said stem, a sleeve associated with said tube, a guard secured to said tube, a clamping plate secured to said stem, means for retaining said sleeve in position with respect tor said tube, said sleeve being rotatable with respect to said tube and knob, and means associated with said stem, tube and sleeve whereby, upon the latter being rotated with respect to said tube, said clampingr plate will be shifted axially and rotatably away from and towards said guard.

4. A razor, comprising a clamping plate and guard, a tube secured to said guard, a stem mounted on said plate, a sleeve enclosing said tube, said tube and sleeve being each formed With track ways, a pin carried by said stem and cooperating with said track ways, and at least one of the latter being spirally disposed whereby relative rotation of said sleeve and tube will cause longitudinal shifting of said stem and plate with respect to said guard.

5. A razor, comprising a clamping plate and guard, a tube secured to said guard, a stem mounted on said plate, a sleeve enclosing said tube, said tube and sleeve being each formed with slots and a pin carried by said stem and extending through said slots, one of said slots being tangentially disposed whereby relative rotation between said sleeve and tube will cause longitudinal shifting of said stem and plate with 'respect to said guard.

6. A razor, comprising a clamping plate and guard, a tube secured to saidV guard, a stem mounted on said plate, a sleeve enclosing said tube, said tube being formed with a slot, said sleeve being formed with a groove'in its in@ ner face, a pin carried by said stem and extending through said slot into said groove, whereby relative rotation of said tube with re- 'spect to said sleeve will cause longitudinal shifting of said stem and plate with respect to said guard.

7. A razor including a tube, a sleeve, a cylindrical member interposed between said sleeve and tube and fixed against movement with respect to the former, said member and tube being formed with slots, a stem slidably disposed within said tube, a clamping plate carried by said stem, a guard secured to said tube, and means connected to said stem and extending through said slots at the point of intersection thereof to shift said stem longitudinally of said tube as said sleeve and member Vare rotated with respect to said tube.
