A CORPORATION OF NEW YORK RAZOR Application filed June 11, 1931. Serial No. 543,508.

This invention relates to a flmctionally and structurally improved razor.

It is an object of the invention to provlde l a device of this character of the safety type and by means of which the parts may readily be shifted in an improved manner, from operl ative to inoperative condition and accordingly by means of which the blade may readily be applied or removed for the purpose of cleaning, drying, etc.

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. i

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

With these and other objects in mind, reference is had to the attachedsheet'of drawings illustrating practical embodiments of -l the invention and in which:

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; I

' 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.

In these views reference numeral 10 indi,

cates a clamping plate and 11 a guard. Pref.` erably 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.

Thus, when the stem is projected the clamping plate will move from the position shown in Fig. l to the position'shown in Fig. 2'conceding that the stem is simult-neously turned in an axial direction. Conversely, if

. the stem is retracted-the clamping plate will 'ride over vthe bevelled edges of the blade-'pothereof.

in which may be spring-pressed as at 17.

nterposed between the stem and the sleeve are primary and

secondary tube members

18 and 19 respectively.

This is conceding that the structure shown in Figs. 1 to 5 is employed. Otherwise, as will hereinafter appear, the secondarytube member may be eliminated. Referring to the embodiment under consideration 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. Thus, by turning the knob with respect to the sleeve it will be obvious that a corresponding movement will occur between the primary and secondary tubes due tothe fact that the s ring-pressed pin rides within the slots of oth of these elements. It is apparent that the pin and stem will be shifte within the slot 21 by engagement with the side edges of the slot 20. This shifting will result in a corresponding movement on the part of the stem and due to the fact that the up er end of the slot 21 is offset, as has been in icated at 26, it is apparent that the final stages of movement will cause the pin to be turnedvin a direction axially to the razor. Consequently, in such final stages the' stem will turn carrying with it the clamping plate so. that the blade may readily be removedl from or applied to the razor.

With a view toproviding for economical manufacture, 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. Usually, however, due ,to the smallness of the part and the fact that it is not desired to slotK the outer sleeve, it is referable to employ an inner tubular memb) So that the clamping plate maylie-when in inoperative position-'asfclose to the stem as vossible, it is referably groovcd, as at 29, in e with the a utment accommodating the recess 30. Also, to prevent water and other foreign substance fromentering the razor a er or the functional equivalent stuiling box structure ymay be resorted to which will additionally have the advantage of maintaining the parts in well-lubricated E condition. This structure as disclosed in Fig. 1 may take the form of an annular groove 30 formed in the stem and packed with grease, or, as shown in Fig. 2, this groove may receive a felt washer or .its equivalent which, if desired, may be impregnated with oil. This element has been indicated at 31. i V

From the foregoing it will be appreciated that among others the several obJects of the invention, as specifically aforenoted, are accomplished. Obviously numerous changes 1n 'construction and rearrangements of the parts may be resorted to without depating from the spirit of the invention as efined by the claims.
