RAZOR -BLADE SHABPENER.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed November 9, 1914. Serial No. 870,947.

- Toall whom iitmay concern Be it known that we, Cmx'roN A. SCOTT and ALEXANDER G. HUG, citizens of the ping. And the narrow extension o'r'tang with the handle to which it is attached forms a means by which the blade can be held and turned from one side to the other .on the sharpening element. But the blades of safety razors, consisting as they usually do of thin strips of steel sharpened on one or more edges, have no natural guide correspending to they back of the ordinary razor blade, nor have they any means by which they may be held and manipulated in. the process of fitting for use when dulled. ()n object of our invention is to afford means by which such blades may be securely held in proper relation to the sharpening element during the various steps of honing, stropging and setting for use. The blade when eld thereby may readily be turned from side. to side to alternate the strokes on opposite sides of the edge, and it is positively held at, the proper angle to give the edges a uniform and correct bevel. And the pre determined angle is held during the stroke, no matter how careless or unskilled the operator. The invention also has for its objects .theprovision of means limiting the angle th-rdhjgh which the pivoted blade "holder may swing, so we ghting or otherwise control-lin \th'a position of the blade holder that it wil swing between the limits of m,ovement prforitled for it, the employment of, a roller strhcture or other means to define the angle at which the blade contacts with the sharpening elemenband which roller, whdn e1nployed, is pre'ferab'lyof sufficient weight to'swing the blade holder by gravity.

The invention has other features that will appear.

The principles of our invention are illustrated In the drawings, in which- Figure 1 is a top view of our improved device, both top and bottom being, however, substantially the same;

Fig. 2 is a side view of the same in operative position;

Figs. 3, 4L and 5 show modifications of the device.

Further describing our invention with reference to the drawings. in which like characters of reference denote like parts throughout-1 is ablade holder having the jaws 22. A recessed portion 3 provides clearance for one part of a razor blade, .while the front edges are closely brought together to receive the edge which is to be presented to the sharpening element. The SflltljaWS may be made of two piecesof spring material brought closely together at the point 4, /'and there secured by screws or rivets 5. The pieces of which the blade holder sides are formed should be continued backwardly and so formed as to provide at 6 orthe reception of a pin 7, which acts as a pivot upon which the blade holder may have limited pivotal movement, as hereinafter described. The axis of swing.- ing movement afforded by the pivotal connection at 7 between the handle and the blade holder is normally substantially fixed with respect to the handle. The further rearward extension of said material to form the arms 8 provides mountings, at the ends of which may be journaled the wheel 9, mounted on the axle 10. The. said wheelshould be provided with a crowning 9',

thereby permitting slight variations from side to side. Should the blade to be sharpencd' not be placed true in the jaws the slight rocking permitted-by this form of the wheel permits the edge of the blade that is.

to be sharpened to lie true on the sharpenin device. ,The wheel is preferably of sucii weight that it will overbalance the jaws and Contents on the front side of the pivot 7. A handle 11 is extended to form the arms or bifurcations 12 at the ends of which, by means of the pin 7, the blade holding jaws are pivoted tothe haudlefi Lugs-'13 and 18' on each side of the arms project inwardly therefrom and are adapted to. engage the this wheel also constituting an engaging meanson the blade holder upon the other of said axis from that upon which the blade edge being sharpened is disposed and "extending laterally'of the holder at each side ther'eof to be engageablewith a shapening'element"simultaneously with. either side of the blade to define the angle of the blade 25 to the sharpening element. This engaging f jm'ea'nS is also desirably weight-ed to turn the "blade holder or carrier member by gra vity,

. ro'neg Thedv-ice'maybe used in connection with a ho'ne' of any desired quality or other i lisharpening means the upper face of which s i'ndicated by the line 15 in Figs. 2, 3 ands.- A blade 16, which is to be sharpened, is sl'ipped between the jaws 2, lcaving the ex' posed edge 16'. The overweighted reardarardly extended portionof the holder causes Who-same to be tilted'by gravity until the incin-bers 8 are in contact with the lower lugs 13' n-the arms 12. The lower portion of 'u'-'h'eel'9-15 thereby adapted to rest upon the upper face "of the sharpening element. and t'opositi-velygga'ge the angle at which the -"edge'107. is applied thereto. After the op er'ator 'has given one or more movements of the edge. upon the hone or-sharpening face, 5 the-device is reversed, when the overweighted arxportionwdrops until themembers 8 are contact, withjl ugs 13', whereby the face o fi the wheel again rests on the sharpening to;'..-assu:me its proper angle. The reversals ofethe device may rapidly follow each other, he jaws automatically taking the proper ang1e .-with the sharpening faceto lmpart the correctjbevcl to the'blade held withip hem. 1he lugs 13,13 constitute'me'ans for I uniting the swinging movement of the .holder with respect to the handle to an ersed as .t edevice is moved from side to at is being1 sharpened projectsscannot be "form the function described for the wheel,

A slightly modified form of the device is shown in Fig, 3, in which the blade holding jaws and the backward extension on the blade holder a re formed in one piece and the extremities of the backwardly extended portion are offset upwardly and downwardly to form bearing points 9, there thus being formed another form of engaging means on the blade holder extending laterally of the holder at each side thereof to be engageable with a sharpening element sin'iultanemislv with either side of the blade and which will determine the angle of the blade holding jaws and take the place of the wheel 9. shown in the other figures. Such angle is determined by the vertical. distance 17 from the point. of rontact to the extended portion of the jaws. or the extended portion thereof prolonged: and corresponds to the vertical radius of the wheel 9. when the me is used as above described. \l'cight may be added as 3v at 17' to overbal 'cethc jaws.

A further moonled form of the device is shown in Figs -i and 5. in which the jaws Q and l" are pimlcd together and to the arms 12 at 4. thumb screw 18 is threaded into the shortarm 18501 the upper blade holding jaw 2". The lower end of the screw bears upon the corresponding inner face of jaw 2 and causes such portions to be forced apart, thereby clampingthe blade firmly within the jaws. The structure shown in l*ig.,3 is also made the subjectv matter of a division of this application. the divisional application bearing Serial Xo. 203,9l'l, filed Nov. 26, 1917.
