KNIFE.

ESPECIPICATION forming part of Letters Patent No. 358,312, dated February 22, 1887.

Application filed October 12, 1886. Serial No. 2l6,005. (No model.) Patented in England October 6, 1886,1\0.l2,734.

To all whom/it may concern.-

Be it known that 1, AUGUST WEOK, mannfacturer, asubject of the King of Prussia, residingatSolingen,Sarnmerthal,Rhein provinz,

5 Prussia, German Empire, have invented certain new and useful Improvements in Knives, (for which Letters Patent have been granted in Great Britain under date of October 6, 1886, No. 12,734,) and I do hereby declare the fol- I0 lowing to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apart of this specification.

Referring to the drawings, Figures 1, 2, and 3 show by vertical sections my improved locking device for po cket-knives,said figures showing the locking-lever in its respective positions when the blade is closed,when the blade is being opened, and when fully open.

The invention relates to that class of knives in which the blade is pivoted to the handle 2 5 and in which means are provided for locking the blade when closed or when open.

A indicates the handle; B the blade-spring,-

secured thereto at d d. The blade B, which may be of any desired or usual construction,

0 is pivoted to the handle at b. As shown, the spring D is curved at its free end, and the blade is pivoted to the handle so as to form a recess therein in rear of the spring, in which recess is pivoted an eccentric lever, E, at e,

3 5 whose nose 1' bears against the back of the spring E, at or near its upper free end, either when the blade is open, as shown in Fig. 3, or when said blade is closed, as shown in Fig. 1.

The lever has-a nail-notch, e,so that it may be rotated on its pivot. It will be seen that 40 when the lever is brought into the position shown in Fig. 2, with its nose 2' out of cont-act with the spring, the blade may be opened,and that when said lever is moved back into its normal position the blade, when fully opened, 5 will be locked by the lever, as shown in Fig. 3.

In practice I construct the low-r so that it may be used for or her purposes. For instance, its inner face, e. may have a tile rill and used as a nail-file, and its nun-r free end maybe made wedge-shaped or pointed and used as a nail-cleaner or as an awl; or any other toolsuch as a cork-screwn1ay be provided with an eccentric tang to lock the blade, as described.

Having thus described my said invention, what I claim is- The combination, with the pivoted blade of a knife and the blade-spring, of an eccentric lever operating on the bladespring to lock the 60 latter and the blade against motion when said blade is closed or opened, substantially as described.

. In testimony whereof Iafiix my signaturein presence of two witnesses.
