JOSEPH SUTTON, OF WAL LA WALLA, WASHINGTON.

TWINE CUTTER.

Specification of Letters Patent.

Patented Feb. 21, 1922.

Application filed April 18, 1921. Serial No. 462,310.

To all whom it may concern:

.Be it known that I, JosEPH SUTTON, a citizen of the United States, residing at Walla Walla, in the county of Walla Walla and State of Washington, have invented certain new and useful Improvements in Twine Cutters, of which the following is a specification. i

This invention relates to devices for cutting twine. and has for its object to provide a means for cutting twine that is sufficiently light in .weight' to be conveniently carried on the finger and when placed ther on is readily accessible for operation.

A further object is to provide a means for cutting twine that is cheap to manu facture, that is ornamental, and upon which may be placed advertising matter.

further object is to provide a means for cutting twine that is a time saverand a twine saver.

A further object is to provide a means for cutting twine that is operable in close quarters, as in opening packages.

A further object is to provide a meansfor cutting twine that will eliminate twine cuts on the hands and by means of its large shoulders is easy' on the finger.

A further object is to provide a means for cutting twine in which the cutting mem-' bers, may be easily removedfor sharpening or renewal purposes.

A further object is to provide a means for cutting-twine, having cutting members so designed that by grinding in the simplest manner the most efiicient cutting means is obtained.

With these and other objects in View reference is now had to the accompanying drawingsin which- Fig. 4 isa front elevation of thecutting member assembled.

Having reference to the drawings, like numerals refer to like parts throughout, and the numeral 1 refers to a' ring which may beof any suitable material, which may be finished elaborately, and may be of various sizes to accommodatethe finger of the.

operator.

The ring is provided with enlarged shoulders 2 to give ample bearing on the finger to insure ease and comfort and upon these-shoulders may be placed advertising matter if desired.

Extending radially from the ring and positioned intermediate of the shoulders is v y a mounting 3 having a groove 4 extending lengthwise thereof and inwhich is secured the cutting members, consisting of a slotted blade 5 having the upper edge of the slot ground on one side only, a second slotted blade 6 which is similarly ground with the I difference that in one the grinding occurs on the opposite side of this upper edge; i. e.,

one may be a left and the other a right hand blade, This method of grinding has a twofold object in that with a slotted member a single grind from one side is a more simple method of sharpening the blade than grinding bothsides, which is due particularly to the slotted feature; and by this method of grinding'cutting edges are obtained that may be placed on theoutside of the cutting member, which upon trial gives the maximum of efliciency.

The slotted blades are so designed that a substantial base 7 is provided which when properly seated in the groove 4 tends to maintain maximum rigidity.

A knife blade 8 has its upper edge 9 'doubly ground to provide a cutting edge which may be placed centrally between the outer slotted blades.

The cutting edge 10 of the slotted blades is tapered upward while the cutting edge 11 of the knife blade is tapered downward and the blades are so designed that the edges form a cutting juncture with one another by two of the edges being above and one below each other; hence with the blades so positioned and ground as above mentioned 'a cutting member is provided having two .upper cutting edges formed on the outerside of the cutting member, and a single cutting edge placed intermediate of said two upper cutting edges.

The blades are provided with apertures 12 which register with one another, and a screw or bolt 13 passes through the mounting, in threaded engagement therewith, and

through these apertures to hold the blades rigidly and removably within the slot 4 of the mounting 3.

. It is now obvious that by removing the screw 13 the blades may be removed for sharpening purposes, and also they may be xi /maxed for renewal or to substitute blades ierming'a larger jaw 14 for cutting heavier twine, such as binder twine or the like.

In use the ring is placed upon the finger with the jaw preferably pointed outward when the device is ready for operation; then the twine to be cut is drawn between the cutting edges of the cutting member and the twine is severed. 1

Having thus described m invention, I claim- 1. In a twine cutter, the combination of a finger ring, cuttingblades mountable in said ring, said cutting blades consisting of a pair of slottedblades sharpened on the upper side of said slot and having the cuttin edges on the outer side thereof, a knife blai le disposed between said slotted'blades and tapered to form a cutting juncture with radially from said ring, broad shoulders onw said ring, a three bladed cutting means, each:

of said blades having a cutting edge and having the cutting edges position with two above and one below each other, the outer of said blades having a single ground edge with the edge formed on the outer side, the

lower blade having a double ground edge and positioned" beneath and between the upper blades, and a means for rigidly attaching said cutting means in said slotted mountm In testimony whereof I ailix my signature.

JOSEPH SUTTON.
