PATRICK J. OBRIEN, OF WICKFORD, RHODE ISLAND.

SHOE-DRESSER KNIFE.

Specification of Letters Patent.

I Pat ted May 16, 1911.

Application filed September 1, 1910. Serial N 589 111.

To all whom it may concern:

Be it known that I, PATRICK J. OBRIEN, a citizen of the United States, residing at Wickford, in the county of Washington and State of Rhode Island, have invented a new and useful Improvement in Shoe-Dresser Knives, of which the following is a specification.

This invention relates to a certain new and useful improvement in shoe dresser knives, and the object of the invention is to produce a knife of this character in which the same is adapted for multiple uses, namely in being worked away from the operator and in being worked toward the operator, the opposite ends of the knife being differently shaped in order to provide for different uses.

A further object of the invention is to provide a knife of this type provided with protecting means in order to prevent the cutting edges from coming in contact with certain parts of the shoe, and to thereby confine the cut of the knife to certain determined points.

Further and other objects of the invention will be later manifested.

In the drawings: Figure 1 is a perspective view of the knife, Fig. 2 is a front elevation, Fig. 3 is a top plan view, Fig. 4: is a rear end elevation, and Fig. 5 is a front end elevation.

The blade designated 1 in the drawings is of concavo-convex cross section and is provided at one end with a handle 2 which is disposed at the rear end of the blade and at the rear longitudinal side edge thereof, the handle being provided with a shank having a foot 3 whereby the handle is secured in position. The rear end edge of the blade is formed with a straight sharp cutting edge 4 which terminates adjacent the longitudinal side edges of the blade, while thefront cutting edge 5 at the front end of the blade is curved in the form of an arc, and extends from the outer longitudinal side edge of the blade to a point adjacent the rear longitudinal side edge of the blade at which point it meet he inner end of a curved cutting point -6', -thecutting edges 5 and 6 conjointly forming a somewhat V-shaped space. Aprotector 7 is formed on the front longitudinal side edge by extending the blade to form a projection which is disposed beyond the cutting edge 4. Similarly at the front end of the cutting blade there is a protector 8 which is formed of an extension of the blade and which has the form of a finger somewhat like that of theprotector 7. Protector 8 extends beyond the front end portion of thecutting point 6 and is raised sufliciently above the blade 1 so as to bring the top of the protector 8 practically on a level with the highest point of the blade 1, so that the cutting point 4 and theedge 6 may be properly sharpened. It will be observed that longitudinally the blade is somewhat concavo-convex for purpose of allowing more ready accessibility of the cutting points to the work.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a shoe dresser knife, a concavo-convex blade having a handle afiiXed thereto, a V- shaped cutting edge at the front end of the blade, said V-shaped edge at one end terminating in a cutting point, and a protector in the form of a finger integral with the blade, and projecting outwardly from the front end thereof beneath the cutting point.

2. A shoe dresser knife composed of a blade having a handle at one end, a curved cutting point at the opposite end of the blade, and a finger carried by the blade and extending beyond the front end portion of said cutting point, said finger underlying the cutting point.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PATRICK J. OBRIEN.
