JAGKVKNIFE.

SPECIFICATION forming part of Letters Patent No. 633,931, dated September 26, 1899. Appiicaiosieanayz,1899. seriaINc. 715.2%. (Numan.)

To [all wwnt it 771/607/ cm1/cern:

Be it known thatI, WILLIAM H. WILKIN- SON, a citizen of the United States, residing at Brookline, in the county of lNorfolk and State of Massachusetts, have invented new and useful Improvements in J ackkni ves, of which the following is a'speciiication.

This invention relatesto Improvements in j knifewithout injury or discomfort and also to protect the pointed ends Of the blades and prevent such ends from projecting above the butt-end of the handle, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure l represents a side elevation ot my improved jackknife, showing the blades closed. Fig. 2 represents a topplan view of Fig. 1 Fig. 3 represents a longitudinal sec tion on the line 3 3 shown in Fig. 2;. and Fig. et represents a side elevation of the improved knife, showing one of the blades Open.v

Similar letters refer to similar parts Wherever they occur on the different parts of the drawings. l

In the drawings, A represents the knifehandle, on which A is what is termed the bolster, and A" the butt.

B B are the knife-blades, pivoted at O, as shown. l

I make the width of the bolster of such a size relative to the hinged blades so that the ing any sharp corners on the blades from sticking up above the bolster, which are liable to tear the clothing when carried in the pockets of garments. The butt A" is extended upwardly above the middle portion of the handle, so as to properly conceal the pointed ends of the blades, and thereby enabling such pointed ends to be sharpened from time to time without causing such ends to project above the butt upper portion 0f the handle,

as is a common objection to ordinary jackknives where thebutt-end is not extended upwardly to cover and protect the pointed end of the blade. .D in Figs. 2 and 3 represents the longitu dinal division-plate between the blades B B. Usually such division-plate extends upwardly even with the upper contour of the handle but this is objectionable, as by grasping the handle such division-plate is liable to cause discomfort to the hand of the user, and'to obviate such difficulty I terminate the upper edge of said division-plate at a proper distance below the upper contour'of the handle, as represented in Fig. 3. f

W'hat I wish to secure and claim isl.L A jackknife provided with one or more hinged blades, a division-plate arranged be` tween said blades and a handle extended outby Letters Patent wardly beyond said division-plate, substanwith the back of the blade orV blades, and

having its butt portion extended beyond the middle part of the handle so. as to serve as a shield or protector for the pointed end of the blade or blades and having a division-plate arranged between the blades, with the handle y extending outwardly beyondsaid plate, substantially as and for the purpose set forth.

' In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

.WILLIAM II. WILKINSON.
