SHOE-KNIFE.

SPECIFICATION forming part of Letters Patent No. 452,999, dated May 26, 1891.

Application filed October 16, 1890. $erial No. 368,251. (No model.)

To all whom it may concern.-

Be it known that I, GUYoN T. FISHER, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Shoe-Knives; and I do declare the following to be a full, clear, and exact 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 the letters of reference marked there.

on,which form a part of this specification.

This invention relates to new and useful improvements in shoe-knives; and it consists in a certain formation and arrangement of parts, producing a knife the handle of which afiords a firm grasp for the hand, anduthe blade of which may be readily adjusted longitudinally to form a long or short blade or to extend the blade as it wears away, as desired, all of which will be hereinafter more fully set forth, and the essential features of the device pointed out particularly in the claims.

In the accompanying drawings, forming a part of the specification, Figure 1 is a side elevation of my improved knife. Fig. 2 is a vertical longitudinal section through Fig. 1. Fig. 3 is a perspective view of the several parts of the knife detached.

Referring to the letters of reference, A indicates the handle of theknife; B, a spring loop or yoke that environs said handle and receives the edges of the k nife-blade between its free ends.

0 indicates the ferrule that receives the free ends of the loop B, and through which the blade extends.

D indicates the blade of the knife, and E a recess or socket in the handle that receives said blade.

The handle A is made preferably of wood, and is essentially ellipsoidal in form, as this form renders the handle strong and substantial, and affords a firm full grasp that does not tire the hand. The groove 2; in the perimeter of the handle, and which extends longitudi nally around the same, receives the spring loop B therein, so that no portion of said loop extends beyond the surface of the handle, as

shown in Fig. 2. The free ends 6 of said loop stand parallel for a short distance, and are provided in their adjacent faces with the grooves c 0, adapted to receive therein the edges of the blade D. The ferrule 0 receives the free ends e of the loop B, and confines them therein, so that the grooves c in the ends of said loop will register with the slot 1) in the outer end of said ferrule. (Shown in Fig. 3.) The knife-blade D is passed through the slot 1) in the end of the ferrule and between the ends c of the spring-loop B, the edges of the blade lying in the grooves c in the ends of said loop, and the rear end of said blade projecting into the recess or socket E within the handle. The ferrule C is provided with a setscrew a passing therethrough, the inner end of which bears upon one end e of the springloop, whereby by means of said screw the ends 6 of the spring-loop may be firmly clamped upon the blade, thus securely holding said blade in place, as clearly shown in Fig. 2. When it is desired to adjust the blade D, the set-screw a is loosened, when the ends e of the loop B will spring apart, releasing the blade, permitting a longitudinal adjustment thereof, whereby the blade may be extended or reduced in length, in accordance with the work to be performed or the use to which the knife is to be adapted, and when set the blade may be again secured by means of the set-screw a, as before described.

It will now be apparent that the herein-described shoe-knife is cheap and simple of construction, the blade of which may be readily adjusted and securely held when set, and that the ellipsoidal form of the handle enables the knife to be firmly held and used for a great length oftime without tiring the hand. This is a veryimportant feature, as the knife is to be used for cutting sole-leather, to which use it is especially adapted by means of the firm hold which its handle affords.

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

1. In combination with the handle ellipsoi dal in form and having a socket along its longitudinal portion, the spring-metal yoke encircling said handle, said yoke having the grooves c, the ferrule, the set-screw and slot ICO in said ferrule, and the-knifc-blade adjustahly I blade adapted to pass through the slot of the attached, as set forth. ferrule and to be clamped by the yoke. 10
