Specification of Letters Patent.

Patented July 13, 1909.

Application filed July 6, 1906. Serial No. 324,997.

T 0 all whom it may concern:

Be it known that 1, JOHN Hnrssnnnnnenn, a citizen of the United States, and a resident of New York, in the county of New York and State of "New York, have invented certain new and useful Combination Knives with Sharpeners, of which the following is a specification.

My invention relates to improvements in cutlery, and particularly to pocket knives, the object of the invention being to provide a detachable sharpening medium which may readily be incorporated in the handle of a tool, so that at any time the tool may easily be sharpened with facility and Without loss of time. a

Another object of the invention, is to provide such a sharpening medium which may belcarried in the tool handle without rendering the same ofinconvenientor bulky size, or awkward for use, will not weaken the structureof the handle, and will be a valu able adjunct to the tool.

With the above, objects in view, my invention consists in pivoting one of the handles or gri s of the tool to the frame or body of the tool ire/mounting a removable whetstone or sharpening medium in such handle,

and in providing means-for lockingthe free end of the handl'e'to the frame; and the invention comprises certain other novel-features of construction, combination and arrangement of parts substantially as herein In the accompanying drawings: Figure 1, IS a side elevatmn of an ordinary pocket knife equip ed with my improvements, one" of the hand es or grips being swungopen to show the sharpening medium therein. Fig.

2, is a front edge view of the same. Fig. 3,

is a transverse sectional View of the knife on line a?; of Fig. 1. Fig. 4, is a broken deta1l viewof a portion at oneend of the knife, to

show the springjcatch for securing the handie in closed osition. 'Fig. 5, is a trans verse section'a view of one of thehandle members with an improved form of sharp? ener therein.

The knife illustrated the accompanying drawings is. of the usual pattern, having the.

rigid face plate A and the pivoted face plate B, forming the handle and also hav ng-the pair of side plates 9 and 10, form1ng the frame, and the blades D and. E, pivotedtherebetween. Tips- 3 and F are secured to the side plates atone end, one of the tips (C) having beveled or undercut edges 3, and the other tip (F) having its inncredge also beveled, as shown at 8, the two tips forming what is known as the head of the knife. A rivet pin 11, passes through the side plates at the front edge and serves to secure the blade actuating spring H therebetwcen. Passing through the side plates'at the end opposite the head, is a pivot pin. 22, to which is pivotally secured the casing or handle member 13, the opposite or free end of said handle member being beveled at an incline to engage the undercut portion of the head. Within said casing is arranged a sl' arpeuer 6, and such s arpener maybe of stone, metal, mineral composition or any other suitable abrading material. Struck up from the side plate 9, near he end at the head of the knife, is a spring tongue 12, having a lip 13, adapted for engagement with the recess in the handle when the handle is closed. other grip or handle member is not hollow like the one just described, but has a strip of sharpening material 4, secured to its lower face. This handle portion has a beveled edge to engage the undercut head at one end, and in' its opposite end is formed a hole or socket 1 to form a bearing for the head of the rivet orpin 2, and thereby lock the handle in place.- A notch 5, is formed in the lower edge at the end of said handle sothat the same may be readily removed. The handle iece B, on its inner face and near its free end 18 formed with the lug or stop let, which holds the file in proper position. v

In the sectional view, Fig. .5, I have shownan improved form of sharpening medium, which comprises a metallic reinforcing strip 6, having a layer of abrasive material 6 and 6 secured to each face thereof. This sharpener is especially valuable when used in connection with a knife, as it is light'and cpmpact, and .may provide both fine, and. coarse abrading surface. The sharpener 4 maybe readily employed for sharpening the blades of other knlvos when required.

I do not wish tolimit myself to the appli-- cation of a sharpener to a knife only, as the device may as well be a plied to other articles'OfcutIer-y, and dit'erent materials for theisharpening med iumlnay be employed.

From the foregoing description taken in connection with the drawings, it is evident that l have accomplished all theobjects the undercut tip, the opposite sidebeingin ed to the end of the form of a hollow casing to form a receptacle, said hollow casing being pivotally secured to the knife and having a beveled end to engage beneath- 'the undercut tip. I

2. A pocket knife having beveled undercut tips, sides to the knife, one of said sides being reinovably secured to the knife and having an inclined end to interlock with the undercut tip, the opposite side being hollow toform a receptacle, said hollow side pivotthe knife and having a bev' eled end to engage beneath the undercut tip, and a s ring catch upstanding from the body of the knife to engage and hold the hollow side closed.

3. A pocket knife substantially-as shown to engage beneath .and described having end pieces provided with beveled undercut tips, sides forming the handle to the knife, said sides havin bev-' eled inclined ends for cooperation wit 'said' of said sides being hollow, and said .hollowsidebeing mounted to be swung open tips, one

to exposethe under face thereon 4.- A pocket knife substantially and described having .end iecesprovided with beveled undercut tips sides forming the tips, one of said sides benig hollow, and said hollow side being to expose the under face thereof, and means.
