RAZOR.

Application filed June 13, 1923. Serial No. 645,054

appliances, and pertains more particularly to razors of the single, sharp-edge type.

One object of the invention is the provision of a razor having a blade which may be especially easily removed therefrom and replaced therein.

A further purpos of the invention resides in supplying adjustment means for the blade to secure the desired cutting or shaving action, such adjustment being toward and from the toothed guard usually employed on such razors adjacent to the sharp edge of the blade.

In order that those skilled in this art may have a full and complete understanding of the invention and its several structural and functional advantages, in the ac companying drawing forming a part of this specification, I have illustrated a desirable and preferred embodiment of the invention, and throughout the several views of such drawing like reference characters have been applied to the same parts.

In this drawing,

Fig. 1 is a face view of the novel and improved razor;

Fig. 2 is a side view of the same;

Fig. 3- is an enlarged, central, vertical or-longitudinal section through the razor;

Fig.4'is 'a fragmentary, lengthwise, central section at right angles to that of Fig. 3 Fig. 5 is a section on the inclined plane 5-5 of Fig. 3; j I

Fig. 6 is a similar section, on a smaller scale, showing the blade in place;

Fig. 7 is a view similar to that of Fig. 6, illustrating the blade with a different adjustment; Y 1

Fig. 8 is a detail view of the blade ad justing mechanism; 7

Fig. 9 is a perspective view of the cam employed for adjusting the blade;

Fig. 10 is a'perspective view of the clamp or face-plate for holding the blade in the razor; and v Fig. '11 is a face-view of the blade. Referring to'these several views ofthe draw g. t w ll he P---ld that the mai round body of the razor comprises a hole low or longitudinally-apertured member 21."

having a round hole 22 through the upper portion thereof whlch communicates with a larger, cylindrical cavity or bearing iu' the lower portion of such element, the top annular face 24 of the member 21 being somewhat inclined or at an oblique angle to'the longitudinal axis of'the body, as is clearly indicated in 3.

Extending outwardly from the face 24;, the part 21 is equipped with a cylindrical,

shouldered, apertured boss 25 and an ineclined or slightly oblique member 26 having along one edge the usual or customary spaced guard teeth 27 of slightly less thick ness than the part-26, is securely and rigid- 1y fastened on the outer or upper portion of the stud 25 bearing at its inner face on the slight shoulder of the stud, the outer portion of which is headed over slightly in the countersunk central hole of the part 26 to center and affix the latter rigidly in position.

Along the central portion of the rear or back edge of this inclined or oblique blade-support 26, it is fitted with anup standing marginal flange or rib 28, and projecting downwardly from its opposite ends there are a pair of cross or transverse,

marginal, spaced flanges or ribs 29, 129,

shown most clearly in the section of Fig. i.

A plate 31 is positioned beneath the bladesupport 26, between its two

flanges

29, 29, which act as retaining guides therefor during the lateral adjustment movement of the part 31, the latter having two, upstanding lugs or

ears

32, 32, eXtending up through cut-

away corner portions

33, 33, of the member 26, as is perhaps most apparent from the illustration presentedin Fig. 5. A round, apertured disk 34, hearing on the surface 24 and carrying adepending, manipulating or adjusting finger or lug 35, is mounted on and revoluble or capable of turning on the lower or inner part of the hollow stud 25, and such disk is equipped on its top or upper face with a curved or arouate cam 36 received in an elongated opening or aperture 37 in .theblad-eadjustment plate (Figs. 8 and 9), whereby turning or rocking of the member 3t'by its handle 35 shifts or adjusts the

lugs

32,32, toward and from the toothed edge 27 of the guard.

Owing to the sli htl y elongated shape of the hole dispose with its longer faggig lengthwise the part 31, this plate 31 has no endwise movement occasioned by the turn ing of the cam, but it is guided in its crosswise or lateral motion by the flanges or

marginal ribs

29, 29, with which its ends coact.

A face plate 38, having a plane upper surface 39 and an outer, slightly-curved or convex face 41,.is supplied-with a threaded stem or shank 42 designed to be removably received in the aperture 22 which extends through the stud referred to, and to project into the threaded inn-er end 43 of a hollow, tubular member 44 fitting and revoluble in the bearing or cavity 23, and supplied with an exposed, enlarged, preferably knurled or ribbed head or terminal part 4 5, by which it may be turned to draw the clamp plate 38 down firmly against the blade to hold the latter fixedly in position.

The member 38' has a downwardly-extended flange 46 which lies to the rear of the flange or rib 28 and the

lugs

32, 32, whereby turning or rotation of the clamjnng-plate is prevented when it is being tightened by the.

The ends of the blade are desirably round ed or slightly convex, asshown in Fig. 11, to

avoid unnecessary sharpcorners or edges, and the longitudinal cutting edge 49 is formed at the junction of the bottomplane face of the blade and a bevel surface 51 at a substantial. angle thereto, for instance, in some cases this may be approximately thirty degrees, which has heretofore been considered altogether too blunt an edge for shaving purposes.

To insert; the blade in the razor, the handle 45 is given a slight turn, and thereupon the blade is pushed entirely into place, the slot 48 receiving the stem 42, and the rear edge of the blade bearing against the front faces. of the two shoulders 32. Then the handle is given a small turn to draw theelamp-plate 358 down into gripping and holding action on the blade, the latter nowbeing held firmly and fixedly in. position.

It will be observed: that-to insert a blade, orto remove one by a reversal of the operation specified, it'is not necessary to separate any parts of the razor, a mere loosening of them being sutlioient for the purpose.

If adjustment of the blade crosswise is desired to modify its cutting action by shifting the blade-edge with "relation'to the toothed guard 27, the handle 4+5 is turned sli htly to free the pressure on, the blade, and then the cam 36 is manipulated by a turning of the handle 35 tomove the lugs 32 forwardly or rearwardly the desired amount, the blade being correspondingly shifted, whereupon the handle 45 is again turned to clamp the blade down immovably in place.

It will be seen that the adjustment of the blade is easily and readily accomplished, and when it is desired to remove the blade, the handle 45 is turned only very slightly, whereupon the blade can be taken out forwardly by grasping its opposite rounded ends between the thumb and finger.

So far as, I know, I am the first person who has provided an adjustment of this kind, whereby the blade may be moved crosswise or laterally to bring it into proper position, and I also believe that I am: the first one to supply a razor of this type wherein the blade may be removed or another one inserted byaw'ery small-turning of the handle and without complete release of any other element.

It will be noted that the handle or lug 35 is up under the head of'the' razor, so that it is not conspicious, and is not at all in the way, and yet it is in a convenient position for ready manipulation when requircd.

In this application 'I have presented only one embodiment of the invention, but the atter is susceptible of a variety of embodi ments differing from one another more or less radically in mechanical features, but all incorporating the-fundamental principles underlying the invention.

The razor-blade disclosed in this patent forms the subjectsmatter of a divisional pending patent application, Serial Number 725,816, filed July 14-, 1924-.
