UNITED STATES PATENT OFFICE,

GEORGE \V. MILLER, OF MERIDEN, CONNECTICUT.

POCKET-KNIFE.

SPECIFICATION forming part of Letters Patent No. 365,086, dated June 21, 1887.

Application filed August 19, 1885.

To all whom it may concern:

Be it known that I, GEORGE \V. MILLER, of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Pocket-Knives, of which thefollowing is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention, while it relates particularly to pocket-knives, is also adapted for use with any blade that it is desirable to cover for coir venienee or safety to the person carrying it in the pocket of wearing-apparel; and it relates to articles of this class having sectional folding handles adapted to embrace and cover the blade or too].

My invention consists in a blade or like part, pivotally connected to one end of which are the grooved handle-sections adapted to open outward, and being brought back to back form a handle, in combination with the peculiar stop that limits the opening of the handle-sections; and it also consists in details of the construction of the device and the parts and their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a plan view of a knife made in accordance with my invention. Fig. 2 is a view in crosssection through the spring-catch on plane denoted by line X X of Fig.1. Fig. 3 is a detail View in cross-section of the device on the plane Y Y of Fig. 1. Fig. t is a detail view of the de- Fig. 5 is a detail side viewof the knife with the han- I dle fully opened and in readiness for use. Fig. 6 is a plan view ot'a blank for forming one of the handle-sections.

In the accompanying drawings, the letter a denotes a blade orlike part that is adapted to be inclosed in and supported by the handle I). The blade or like part has a shank, a, on the opposite edges of which two pivot-holes are formed, and each part of the sectional handle is pivotally connected to this shank by pivots c, suitably headed to securely connect the parts.

The handle I) is made of sheet metal folded up from the blank (Z, that is cut or stamped from a sheet of metal-as steel or brass-by means of suitable dies. The pivot-holes d sci-m1 Naeireii. (No model.)

against and resting on the end of the shank.

One of such sections, 7), is pivoted to the shank of the blade in such position that the latter may be closed upon it along one edge and extend halfway across its widtl1,while the other handle-section, Z)", is in a similar manner pivotally connected to the opposite edge of the shank, the two handle-sections when folded together with the opened edges opposite each other more or less completely inclosing and covering the blade or like part, as shown in Fig. 1 of the drawings.

To the free end of the handle-sections is connected a spring-catch, c. This catch is preferably made of a link, 0, that is a piece of metal pivoted between the ears (1 on one of the handle-sections with its free end adapted to swing between and to be clasped by the ears (1 on the opposite handle-sections. The space between these cars d in their normal position is slightly less than the catch is in thickness, with the result that when the latter is thrust between them they hold it with a frictional grasp depending upon the resiliency of the material of which the handle-section is composed. The function of the catch is to hold the sectional handle in the closed position, as shown in Fig. 1, or the open position of the handle, as shown in Fig. 5.

The handle-sections b I) are by the striking of the step (2" against the end of the shank held slightly apart along the back of the sections, except under the hold of the catclnwith the result that the blade is held by the sectional handle with great strength and rigidity. In the absence of the springeatch a firm and rigid hold of the handles upon the blade is insured by the pressure of the hand upon the handle-seetions in using the device.

By the use of the term blade in the following claims 1 mean to include not only a cutting implement, but also any other that for convenience or safety may be borne on the shank and inclosed within the sectional folding handles.
