NAIL-TRIMMER.

SPECIFICATION fOIming part Of Letters Patent N0. 794,234, dated July 11, 1905.

Application filed April 6, 1903. Serial No. 151,275.

To all whom it may concern:

Be it known that I, HENRY LA (Laws, of Auburn, in the county of Cayuga and State of New York, have invented a certain new and useful Nail-Trimmer, of which the following is a specification.

My invention has for its object the production of a nail-trimmer which is particularly simple in construction and highly durable and effective in use; and to this end it consists in the combinations and devices hereinafter fully set forth, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming part of this specification, in which like characters designate corresponding parts in all the views.

Figures 1, 2, 3, and 4 are respectively top plan, longitudinal sectional view, end View, and isometric view of a preferable embodiment of my invention, the nail-support and the locking member being shown in different positions in full and dotted lines in Figs. 1 and 2. Fig. 5 is a sectional view of a modified construction of knife for my invention.

1 and 2 are respectively the nail-support and knife of my nail-trimmer. The part 1 is generallyformed with side walls 8, arranged at substantially right angles with the main portion of said part 1, and is provided at its front end with an opening 4:, a convex upper face 5, of soft metal, beneath and in front of the opening 4 for engaging the under surface of the nail, and an end face 6 for engaging the finger or toe and regulating the cutting of the nail.

1n the preferable construction of my nailtrimmer the rear end of the knife 2 is arranged beneath the like end of the nail-support 1 and is extended rearwardly beyond said part 1, and the front end of the knife 2 is formed of less width than the contiguous main portion thereof and is provided with upward, forward, and downward extensions 7 8 9, the forward extension 8 being arranged in the opening 4 and having depending cars 10, pivoted to the side walls 3, and the downward extension 9, terminating in a concave cutting edge 11, of hard metal, cooperating with the face 5 for cutting the nail. The advance surface of the knife 2, terminating in the edge 11, and also the face 6 of the nail-support are extended rearwardly from their opposite ends, as shown in Fig. 1, for facilitating cutting of the nail rounding. The front end of theknife 2 is usually also formed with a lengthwise corrugation 12 for stiffening said end and with a notch 13 in the upper face of the forward extension 8. Although the knife 2 is preferably composed of a single piece of steel, it will be obvious that the same may consist of a main body 14 and a detachable blade 15, as illustrated in Fig. 5.

16 is a spring for moving the support 1 relatively to the knife 2, and 17 is a member for locking the support 1 against the action of the spring 16. As generally constructed the intermediate portion 18 of the spring 16 bears against the upper face of the intermediate part of the knife 2, and the ends of said spring are arranged between the side walls 3 and provided with lateral extensions 19, fixed to said side walls. By constructing the spring of a single piece of spring-wire to provide an intermediate portion and approximately parallel side arms the right-angular terminals or extensions 19 can be readily sprung into the openings 19 in the side walls of the member 1. This arrangement will insure the proper disposition of the spring, permitting the spring to be easily attached and detached and insuring the same against accidental displacement when in its operative position. The locking member 17 is provided with a depressed rear 1 end to the knife 2 at the rear of the support 1. Its intermediate portion detachably engages the upper face of the support 1, and its front end is formed with a point 20, detachably arranged in the notch 13. The under face of the member 17 is usually provided with a roughened surface for filing the nails.

By reference to Fig. 1 it will be observed that the end face 6 is in the form of a projecting lip extending longitudinally from the member 1, and the surface for engaging the finger or toe is provided with stop means, conveniently illustrated as being the ends of the side walls of the member 1. The rigid upstanding edges of these side walls will insure a uniform cut being made in each instance.

The construction and operation of my nailtrimmer will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be apparent to those skilled in the art that more or less change may be made therein without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A nail-trimmer comprising a member having one end provided with an opening and with a supporting-face for the nail, and a second member consisting of a strip having one end arranged beneath the other end of the first member and its opposite end extended upwardly and forwardly, and downwardly, said opposite end being extended through said opening of the first member, and the downwardly-extended portion terminating in a cutting edge for cooperating with the supportingface, one of said members being movable relatively to the other, substantially as and for the purpose specified.

2. A nail-trimmer comprising a member having one end provided with an opening and with a supporting-face for the nail, and a secand member consisting of a strip having one end arranged beneath the other end of the first member and its opposite end extended upwardly and forwardly, and downwardly, said opposite end having a substantially lengthwise corrugation and being extended through said opening in the first member and the downwardly-extended portion terminating in a cutting edge for cooperating with the supporting-face, one of said members being movable relatively to the other, substantially as and for the purpose described.

3. A nail-trimmer comprising a pair of members provided respectively with a supporting-face and a cutting edge cooperating with each other, one of the members having one end arranged below the like end of the other member and its other end arranged above the opposite end of said other member, and one of said members being movable relatively to the other, a spring having its intermediate portion engaged with one of said members and its ends formed with lateral extensions fixed to the other member, and means for locking the relatively movable member against the action of the spring, substantially as and for the purpose set forth.

4. A nail-trimmer comprising a pair of members provided respectively with a supporting-face and a cutting edge cooperating with each other, one of the members having one end arranged below the like end of the other member and its other end arranged above the opposite end of said other member, and one of said members being movable relatively to the other, a spring for moving the relatively movable member, and a third member for locking the relativelymovable member against the action of the spring, said third member having one end pivoted to one of the pair of members, and its other end provided with apoint for detachably engaging with said one of the pair of members, substantially as and for the purpose specified.
