Definitions

  • To/LZZ whom t may concern Be it known that l, lnviNG SMITra, a citizen of the United States, and a resident of Winsted, county of Litchfield, and State of Connecticut, have invented certain new and use ful Improvements in Safety Razors, of which the following is a specification.
  • This invention relates to razors, and more particularly to a safety razor having a thm fla-t handle arranged obliquely to the edge of the blade so that the correct diagonal shaving stroke will be easily obtained by the user.
  • the object of this invention is .to provide a device of the above nature which will be simple in construction, inexpensive to manu; facture, easy vto manipulate, ornamental in appearance, and very efficient and durable 1n use.
  • Fig. 1 represents an end view of the first form of safety razor embodying the inven- Fig. 2 is a side sec-tional view of the same, taken along the line 2-2 of Fig. 1, looking in the direction of the arrows.
  • Fig. 3 is a top sectional'view of the same, taken along the line 3-3 of Fig. 2 looking in the direction of the arrows.
  • Fig. 4 is a cross-sectionalv'iew of the handle of the safety razor, taken along the line 4-4 of Fig. 2.
  • Fig. 5 is an end view of am'odified second form of the invention.
  • Fig. 6 is a side sectional view of the same, taken along the line 6-6 of Fig. 5, looking in the direction of the arrows.
  • Fig. 7 is a top view of the second form o safety razor.
  • Fig. 8 is a perspective view of the clamping plate employed with the second form of the invention.
  • Fig. 9 is a perspective view of the lower portion of ythe handle of the second form of the invention.
  • Fig. 10 is a slde View, partly in section, of
  • Figs. 11 and 12 are to and end views-re?.
  • Figs. 13 and 14 are top views of two modifiedwforms of razor blade.
  • Fig. 15 is a top View of a modified form of guard member adapted for ruse withany of the above-illustrated forms of safety razor.
  • Fig. lfiw is a side sectional view of the same
  • Fig. 17 is a top view of another modified form ofv guard member.
  • Figs. 18 and 19 are-top and end views respectively of a modified form of clamping plate to be used with the guard member shown infFigs. 15 and 16.v

  • the swivel collar 48 is preferably knurled on its exterior and has an inwardly directed lug 49 at its top adapted to fit loosely within an annular slot 50 in a flat handle member 51, said handle member 51 having fiat sides 52 and 53 parallel to the ends of the clamping plate, as in the first illustrated form of 'the invention.
  • the hand e 51 is provided with a slot 54 adapted to fit snugly over the fiat tongue 43 of the bed post.
  • a still further modified third form of the invention is shown lin Fi 10.
  • This form of razor is identical ywit the forms shown in Figs. 5 to 9, except that the bottom of the handle is provided with a flat tongue 55 and the center post of the clamping plate is provided with a slot 56 fitting over said tongue 55 for holding the handle 57 at the correct oblique position.
  • Figs. 11 to 14 three modified forms of razor blade are illustrated.
  • the blade is in the shape of an oblique parallelogram correspondingto the shape of the clamping plate as shown in Figs. 3 and 7.
  • the blade is provided Vwith a pair of end apertures 58 and 59 for fitting over the end ⁇ pins of the clamping plates, and said blade has a central aperture 60, the latter having the shape of an oblique parallelogram with its sides parallel tothe ends of the blade.
