Definitions

  • This invention relates to a flmctionally and structurally improved razor.
  • a further object of the invention is that of providing a device of this type in which the parts may readily be adjusted to be used in such manner that, exactly thedesired type of shave will result and in which this adjustment may be achieved in a ready and simple manner.
  • a still further object is that of providing a razor in which the parts will be constructed 'in such manner that there will be minimum danger of deleterious action by the entrance of foreign agents and in which the parts will be guarded against rust and other destructive actions.
  • Stilll another object is that of providing an apparatus of this character the parts o which will be relatively few in number and each individually simple and rugged in construction land capable of manufacture largely by automatic machinery, these parts being capable of assembly'by relatively unskilled .labor and when so assembled operating over long periods of time With freedom from any diiiiculties whatsoever. j
  • Fig. 1 - is a partly sectional side view of a razor and showing the parts thereof in operative condition;
  • Fig. 2 is a similar view showing the parts in open or inoperative condition
  • Fig. 8 is a side elevation (partly in section) of one of theA actuating tubes
  • Fig. 4 is a similar view of a secondary tube and prior to the forming thereof;
  • Fig. 5 is a transverse sectional viewfof this tube after the forming operation and stem portion 'of the razor.
  • this guard has extending from its up- -per face a blade-positioning abutment 12 which, as shown in certain of my preceding appllcations, may have inclined side edges for cooperation with the end edge of the clamping plate as in a manner hereinafter described. Also in the present application there has not been illustrated the blade. ⁇ VThis forms the subject matter ofother pending applications presently before the United States Patent Oiiice.
  • the guard as illustrated may be of the double-edged type and have a comb ⁇ portion 13 extending along each of its side edges. Also, as illustrated, it is preferably 'curved so that 'a blade positioned thereon and retained in position bythe clamping plate will be subjected to a greater or'lesser extent of transverse flexure.
  • This guard is preferably supported by or may in fact form an integral part of. a sleeve 14 which forms the main
  • the 'clamping plate is ivotally mounted asv at 15 by a stem 16 slida ly disposed within the bore of the The clamping plate' 4tends to' tilt. This is accomplished by any suitable provision as, for example, by having one end of the stem over-weighted or by having the pivot suicientlyfhigh that a condition of unbalance is bound to prevail.
  • the stem is retracted-the clamping plate will 'ride over vthe bevelled edges of the blade-'pothereof.
  • primary and secondary tube members 18 and 19 respectively.
  • the secondarytube member may be eliminated.
  • the primary tube member serves as a shift element
  • the secondary tube member serves as a guide and the spring-pressed pin extends into slots 20 and 21 forming parts of these tubes.
  • the secondary tube is retained against rotation, with respect to the sleeve, by, for example, forming the same with an opening into which a retaining stud 22 extends, the latter forming an integral part of the sleeve.
  • The'primary tube is coupled to an operating knob 23, the outer surface of which may be knurled and around the extension 24 of which a retaining washer 25 may be disposed. This washer, in addition to preventing improper contact of the sleeve and knob, wi'll also serve as a guide for the knob and tube associated therewith.
  • the secondary tube 19 may be struck from a single fiat sheet of material, as illustrated in Fig. 4. This sheet may then be curved, as in Fig. 5, and finally be properly disposed within the sleeve of the Irazor. If this is notjdesired the structure shown in Fig. 6 may beitilized, in which the groove 27 corresponding to the slot 21 is formed in the inner face of the sleeve 28.
  • a razor including a guard, a clamplng plate, a sleeve secured to said guard, a member slidable within said sleeve for shifting said plate, one of said last named elements ⁇ 9 0 being formed with a recess and packing means disposed within said recess for cooperation with the, second of said elements.
