GEORGE E. TRIPP, OF CHELSEA, MASSACHUSETTS.

TWINE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 425,194, dated April 8, 1890.

I Application filed December 20, 1889. Serial No. 334,376. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. TRIPP, of Chelsea, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Twine and Thread Cutting Rings, of which the following is a full,

. clear, and exact description. r' This invention relates to rings having an at- ,J' tached cutter and designed to be slipped upon io the thumb or finger to facilitate the cutting of string, twine, or threadas, for instance, string or twine by persons engaged in wrapping up bundles, boxes, or other packages in storeswithout having to resort to a string- I 5 cutter ona counter or picking up a separate cut-ting-instrumentfor the purpose of cutting the string outside of the knot on the wrapped parcel.

The object of my invention is to construct a string or thread cutting ring of this description whichshall be both simple and comfortable to wear, and that will admit of the cutter being easily sharpened without taking it off the ring; and to these and other ends the in- 2 5 vention consists in a novel construction of the ring with its attached cutter, substantiallyas hereinafter described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a view in perspective of a string or thread cutting ring embodying my invention and as applied to the thumb of the person engaged in severing a piece of twine by it. Figs? is a side view, and Fig. 3 a front end view, of the cutting-ring detached from the thumb or finger of the wearer. ZS A indicates the ring, which is made of a piece of spring-brass or other metal, and which is constructed of tapering width in a downward direction, with its meeting ends left open below, as at b. This construction provides for the elastic and easy fitting of the ring upon the thumb or finger of the wearer, and so that of the bending of the thumb or finger with perfect freedom.

B is the cutter, which is secured by rivets or 5 otherwise on the top or broadest part of the ring, and which is approximately of V shape on its cutting-edges c, that lie in the same plane as the axis of the ring. Said cutter, which is made of steel, having its cuttingedges on the inside of its body, allows .of the cuttingring being worn at all times without inconvenience, and without the risk of cutting or-destroyin g other articles with which it may accidentally come in contact. The cutter, too, may easily be sharpened without removing it from the ring, and the whole cutting-ring is made up of but two parts-that is to say, the ring proper and its attached cutter.

To provid e for cutting heavy string, the'back 6 5 edge of the ring, toward which the widest part of the cutter inclines, is rolled over, as at d, to form a guard to prevent the ring from cut-tin g the thumb or finger when pulling backward on the string 8 to cut it.

To cut the line of string after tying a parcel Y or box with it, the portion of the string nearest to and outside of the knot is placed over the knife on the ring upon the thumb or finger of the one hand, and the string held by the other hand, and pulled quickly down and from front to back by suitably swinging said latter hand.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is X As an improved article of manufacture, a twine-cutter consisting of the open ring A of a tapering width in a downward direction, and having its rear edge rolled over at d to form a guard, and the blade-like cutter B, having approximately V-shaped cu tting-edges c c, and secured to the broadest part of the ring, with its cutting-edges in the same plane as the axis of the ring, as specified.
