FINGER-NAIL KNIFE.

SPECIFICATION forming part of Letters Patent No. 415,462, dated November 19, 1889.

Application filed March 26, 1889. Serial No. 304,803. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL E. JONES, of Canon City, in the county of Fremont and State of Colorado, have invented a new and Improved Finger-Nail Knife, of hich the following is a specification, reference being had to the annexed drawings, forminga part thereof, in which- Figure 1 is a side elevation of my improved nail-knife with the blade open. Fig. 2 is a side elevation with the blade closed and the side of the handle removed, and Fig. 3 is a back view.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to provide an improved knifefor cleaning and trimming the finger-nails.

My invention consists in the combination, with a knife-handle provided with a backspring, of a'blade pivoted in the handle and provided with shoulders for engagement with the spring, and having in the back thereof serrations or file-teeth, which lie within the edges of the handle when the blade is closed.

The invent-ion also further consists in the combination, with a knife-handle having a concave recess in the back thereof and provided with a throat extending through the handle, of a cutter inserted in the back,with its edge projecting into thethroat and adapted to pare the edge of the nail.

Between thecheek-plates a a of the handle A is pivoted a blade B, provided with the shoulder c and cutting-edge d, curved rearwardly and terminating at the back of the blade. In the back of the blade are formed serrations or file-cuts e, which extend from the shoulder f to a point near the free end of the blade, and in the side of the blade, near the free extremity thereof, is formed a nick g, for convenience in opening the blade. At a corresponding point in one side of the handleder f when the blade is opened and the shoulder 0 when the blade is closed, thus holding the knife-blade in either an open or closed position, as may be required.

In the end of the handle opposite that containing the blade is secured a block j, forming between itself and the thick end of the spring a throat 7.1, and in the back of the handle at this point is formed a concave notch Z, which is deepened in the spring 1' and the block j to form a groove for receiving and guiding the edge of the nail. In a recess in the block j is placed a cutter m, which projects into the throat 7e and slightly beyond the block j and the spring i, to allow it to come into contact with the edge of the nail.

When the blade is closed, as shown in Fig. 2, the serrations e on the back of the blade are available for filing the end of the nail, and when the blade is open it may be used for trimming or cleaning the nails, or for any purpose for which an ordinary knife could be used.

I'lavin g tlrus described my invention,I claim as new and desireto secure by Letters Patent 1. In a nail-knife, the combination of the handle A, provided with the notch h and the spring i, and the blade 13, provided with serrations on the back thereof, the blade being arranged with reference to the handle, so that the serrated edge is below the cheek-plates of the handle when the blade is closed, substantially as specified.

2. The combination of the handle A, provided with the concave notch l and throat 7c, and the cutter m, projecting into the throat 7c, substantially as specified.

3. The combination of the cheek-pieces a a, the blade B, pivoted between the cheek- Witnesses:
