JAMES E. SMITH, or URBANA, ILLINOIS.

PARING-KNIFE.

To all whom it may concern: 7

Be it known that 1, JAMES E. SMITH, a citizen of the United States, and residing at Urbana, in the county of Champaign and State of Illinois, have. invented a certain new and useful Improvement in Paring- Knives, of which the following is a specification.

This invention relates to paring knives adapted for paring, slicing and coring fruits and vegetables.

One of the objects of this invention is to provide a paring knife which is constructed and adapted to pare, slice and core fruits, vegetables or the like with minimum waste.

Another object is to provide a paring knife which is simple in construction and operation, effective in its action and cheap to manufacture.

Further objects Will appear from the detail description taken in connection with; th accompanying drawing, in which,

I Figure 1 is a side elevation of a paring knife embodying this invention;

Fig. 2 is a section partly in elevation along the line 22, Fig. 1.

Fig. 3 is "an enlarged section 011 the line 3-3 Fig. 2, showing the guard in paring position;

Fig. l is a view similar to Fig. 3, but showing the guard in coring position; and,

Fig. 5 is a view similar to Fig. 3, but showin the guard in inoperative position.

eferring now to the drawing, 1 designates a handle which may be constructed of wood or any other suitable material and.

provided with a reduced portion 2 adapted to receive a ferrule 3. The reduced portion 2 of the handle is flattened as shown at 4, to receive a blade 5, which is secured to the handle by means'of suitable fasteners 6. This blade is sharpened along one edge 6, and has a point 7. v

Secured to or formed integral with the ferrule 3, is a guard 8 having one or both of its edges sharpened, as shown to form a coring blade, and having its end 9 slightly pointed. The ferrule hasan ear 10 overlying the reduced end 2 of the handle, and which is perforated to receive a bolt 11 having a head 12, engagingthe ear l0, and threaded at its other end toreceive a wing nut 13. The guard is in cross-section on the arc of a circle, the inside radius of which is so proportioned that the. blade will just about form a cord at the arc.

I Specification of Letters r atent. Patented Feb..24:, 1920- Application fi1edJu1y1 9, 1913/ Serial no. 245,735. 7'

The ferrule with its attached guard is adj ustable rotatively about the handle, and this ferrule and its guard can be locked in any positionof adjustment by the wing nut 13. By adjustingthe guard,-as shown in Figs. 1, 2 and 3, the knife is adjusted for paring, and the guard acts in this case to determine the thickness of the peel. This thickness can, of course, be adjusted by adjusting the opposing edge of the guard toward and from the corresponding edge of the blade. In this position of the parts, the knife can also be used as a slicer. By adjusting the blades, as shown in Fig. 4;, the knife is adapted for coring, since it can be inserted in this position into an apple or other vegetable and the core cut out. When it is desired to pack or lay aside the knife, the guard can be moved to inoperative position, as shown in Fig. 5, at which time it protects theedge of the blade.

It will, therefore, be seen that the invention accomplishes its objects. The paring knife embodying this invention is simple in construction and cheap to manufacture; it can be used for a number of different operations, and can be quickly adjusted to any desired position. Due to the fact that the ends of the guard and blade are left free, which is accomplished by the strong rigid construction of the arcuate guard, clogging of the space between the guard and the blade is obviated. The knife can readily be taken apart and cleaned, and can also be readily sharpened, and the adjustable relation of the guard with respect to the blade permits the wear, due to sharpening, to be readily taken up.

It is obvious that various changes may be made in the details without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific construction paring blade mounted thereon, and a coring blade mounted on said handle, adapted to cooperate With said paring blade as a guard for the same.

4. A paring knife comprising a handle, a paring rblade mounted thereon, a coring blade mounted onsaid handle, adapted to cooperate With said paring blade as a guard for thefsame, and means for adjusting said coring iblade.

5. A paring knife comprising ahandle, a paring blade mounted thereon, a coring blade mounted on ,said handle, adapted for selective adjustment to coring posit-ion, or

to paring positioh cooperatively with said paring blade as a uard therefor.

6. A paring kni e, comprising, a handle, a blade mounted on said handle, a ferrule mounted on said handle and having an inwardly projecting portion extending toward the center of said handle to serve as means for locking said ferrule to said handle, means,

for looking or releasing said ferrule, and a guard mounted on said ferrule.

. In testimony whereof I afiix my signature this 20th day of February, 1918,

JAMES SMITH.
