Application filed February 17, 192 2. Serial No. 537,172.

-, plements and especially to an implement for sharpening cutlery, such as knives, razors or the like, but not limited in its scope or utility to such association.

An objectof the invention is to provide an implement having abutting, abrading or grinding members presenting an angle therebetween of the'required angle for the edgedesired between which "the implement is moved or drawn and with improved means for holding such abradingmembers in such engaging position.

A further object of the invention is to provide a handle having a member slidable and adjustable therein, extending to form jaws between which are engaged abrading members held at an angle relative to each other and between which a knife, razor or the like is moved or drawn to abrade and sharpen both sides of the cutting edge simultaneously.

With these and other objects in view, the invention comprises certain novel parts, elements, features, combinations and arrangements as disclosed in the drawings together with mechanical equivalents thereof as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a View partly in edge elevation and particularly in diametrical section showing the construction and arrangement of parts forming the present invention,

Figure 2 is a view in side elevation from the side indicated by arrow 2 at Figure 1.

Like characters of reference indicate cor-. responding parts throughout the several views. v

The improved sharpening implement which forms the subject matter of this application comprises a pair of jaw members 10 of similar or identical construction having recesses 11 formed therein, in their proximate faces, for the receipt of abrading or sharpening members 12.. It is obvious that these abra-ding or sharpening members 12 may be of any usual and ordinary material employed for the purpose and it is desired that said members shall-beheld in such re 'lati'on to each otheras to present an angle indicated at 13 between which the edge of a knife, razor or the like may be moved orig drawn, such" angle corresponding to the angle of grinding at the edge of the device to be sharpened. i

The means for maintainingfthe members 12 in such relation consists of a tube 14c serving also as a handle'into, whichthe ends of the jaw memberslO are i11serted,-such ends being provided with :threaded' se'ctions 15. i V i Into the end of the tube 14oppositethe end in which the jaws are inserted a sleeve 16 is inserted, being internally screw threaded as indicated at 17 to engage ,threads 15 of the jaw members,- and providedwith a knurled head 18, servingto'manipulate the sleeve 16 for exerting tension upon the jaw members and also to abut against the end of the tube. 14 to prevent the. displacement of the parts. i

In assembling the device, the abrading members 12 are inserted into the recesses 11,

manually, and the jaw members 10 held together temporarily and inserted into the tube 14. The sleeve l6'is now inserted in the opposite end engaging the screw threads 15 of the jaw members and by manual ro tation the parts are secured together in the usual well known manner, drawing the aw 'members down into the tube 14: and by rea-' son of their divergence as indicated more particularly at Figure 1 serve 'toclamp the abrading members firmly together. It is obvious, of course, that by manipulating the knurled head 18 and the screw sleeve 16 attached thereto greater or less tension may be exerted upon the abutting, abrading members It is to be understood, of course; that the angle 13, shown at Figure 1, as the angle between the members 12 is in no way controllin as to the angleto be employed and that such angle may be varied to correspond to the preferred angle of grinding of the knife or the like, which is to be sharpened. It is also obvious that the same holder, consisting of the jaws l0, tube 14 and associated parts, may be employed to hold interchangeable abrading members 12 having different angles 13, or composed of difierent material for coarse and fine grind 'bers longitudinally within the ing or for the grinding upon a razor, ordinarily known as honing.

The arrangement of the parts forms a very convenient implement for the purpose and by reason of the ready and convenient interchangeability of the abrading members a number of such abrading members may be furnished with each handle outfit,

whereby acomplete grinding outfit is provided for different kinds of grinding upon different knives or other cutlery.

What I claim to be new is: v

V 1. A grinding implement comprising a tubular member, jaw membersinserted into the tubular member and diverging beyond the end thereof, abrading members retained in abutting position by the diverging portions of the jaw members and presenting a grinding angle, and means to exert tension upon the jaw members.

. 2 A grinding implement comprising jaw members juxtaposed throughout a portion of their lengths and diverging throughout another portion of their lengths, a tube surroundingthe juxtaposed portions, abrading members held between the diverging portions, and means to draw the jaw memtubular member to exert varied tension upon the diverging portions.

3. A grinding implement comprising a tubular member, a pair of jaw members having abutting portions inserted within the tubular member and having other. 'portions diverging beyond the end of the tubular member, means extending into the tubular member for moving the associated jaw members longitudinally as an organized structure for exerting compressing stress upon the diverging portions, and abrading members held between the diverging portions adjacent their extremities, presenting a grinding angle therebetween.

4, A grinding implement comprising diverging jaw members having sockets formed in their proximate faces ad acent their divergent ends,

interchangeable abrading members located in the sockets, a tensioning I sleeve, and means to move the tensioning sleeve toward the divergent ends of the jaw members to exert tension upon the abrading members to hold them normally in abutting position with a grinding angle between'portions of said grinding members. I In testimony whereof I hereunto aflix my signature in presence .of two witnesses. I
