WILLIAM MOORE, OF DULUTH, MINNESOTA, ASSIGNOR OF FIFTY-ONE ONE- HUNDREDTHS TO JOHN E. MATTSON, OF DEER WOOD, MINNESOTA.

TWINE-CUTTER.

Specification of Letters Patent.

Application filed October 9, 1911.

To all whom it may concern:

Be it known that 1, WILLIAM MOORE, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Twine-Cutters, of which the following is a specification, reference being had to the accompanying drawm s.

This invention relates to twine cutters and has for its object to provide a device of this type so constructed that the danger of in jury to the operators hand by the cutting blade is eliminated.

A further object of the invention is to produce a twine cutter provided with means for holding the free end of the twine in such a manner that, when the device is to be used, the twine will be in a convenient position for the tying of bundles and boxes, the unwinding of the twine being in no way interfered with.

A. still further object of the invention is to produce a device of this character which may be conveniently and comfortably grasped by the operator and retained until the package has been tied and the twine severed.

With the above and other Objects in view, the invention resides in the novel features of construction, combination and arrangement of parts, as will be hereinafter fully described, claimed andillustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the device, the same being at rest upon the counter; Fig. 2 is a longitudinal sectional View of the same; Fig. 3 is an end view of the device.

The device consists of a pair of metallic plates 1, the inner faces of which are arranged in opposing relation and are adapted to move toward and away from each other to clamp and unclamp a circular cutting blade 2. The outer face of one of the plates 1 is provided with a hollow extension 3, the same being for the purpose of reducing the weight of the device. A recess 4 is formed in the opposite side of the other plate 1, the purpose of which will be hereinafter described. Passing through the outer end of the hollow extension 3 is an provided with a central bore 8.

eye bolt 5, the shank 6 of which is swivelly mounted. The other plate 1 is also provided with a projection 7, the same being A cap 9 is provided and is adapted to telescopically engage the outer end of the projection 7. The outer edge of the cap 9 is provided with a flange 10, the purpose of which will be hereinafter described. Formed integral with the flange 10 is agrooved securing bar 11, which is slidably mounted in the eye,12 of the bolt 13. The bolt 13 is threaded at its lower end for engagement with the bore 8, the extreme inner end being engaged by a nut 13 to prevent accidental displacement of the same, said nut being positioned in the recess 4. Surrounding a portion of the bolt 13 is a coil spring 14, the inner end of which rests upon the outer end of the projection 7 and the outer end of said spring is adapted to rest against the inner side of the flange 10. The tension of the spring 14 may be regulated upon adjustment of the bolt 13 and nut 13, whereby the twine 15 is yieldingly secured to the device, but, at the same time, permitted to slide freely in the eye' 12 and over the grooved bar 11 when tying a package or the like.

The plates 1 are each provided with a plurality of obliquely disposed peripheral slots 16, said slots being adapted to register to permit the twine to be severed to be guided to the cutting edge of the blade 2. To prevent the twine from becoming tangled it is threaded through the eye of the bolt 5 and the registering slots 17 of the plates 1 and the cutting blade 2 and then through the eye 12 of the bolt 13.

The opposing plates 1 are each provided with perforations 18, which when in alinement register with openings 19 formed in the blade 2. Clamping screws 20 are then passed through the respective perforations and openings, whereby said plates firmly clamp the blade.v

In use, the operator grasps the device in the right hand and the twine with the left hand, and, as the twine is permitted to slide freely through the eye 5, slots 17 and eye 12, the same may be unwound to tie packages, and, after this operation, the twine is Copies of this patent may be obtained for passed by the left hand of the operator through the registering slots 16, whereupon pressure being applied the twine is severed.

By slight changes in the construction of the slot 16, the device may be equally as well adapted for use by left-handed persons, that is to say, they may be arranged radially.

Having thus described the invention, I claim l. A twine cutter including a pair of plates provided with registering peripheral slots and with perforations, a cutting blade having openings registering with said perforations, fastening devices passing through said perforations and openings to clamp the said blade between said plates, one of said plates having an extension, an eye bolt swivelly connected to the outer end of said extension, the other plate having formed on its outer face a projection provided with a longitudinal bore, the inner end of which is enlarged to form a recess in the inner face of said plate, a nut mounted in said re cess, a cap telescopically mounted on said projection, an eye bolt extending through said bore into said recess and engaging said nut, a grooved bar formed integral with the outer end of the cap and adapted for sliding engagement in the eye of the last named eye bolt, and a coil spring surround:

ing said bolt for holding the grooved bar in yielding engagement with the free end of the twine when passed through the eyes of said bolts.

2. A twine cutter including a pair of plates, a blade clamped between said plates, an eye bolt carried by one of said plates, the other plate being provided with a projection formed with a longitudinal bore, a cap slidingly mounted on said projection, a spring mounted in said cap and tending to move outwardly on the projection, the cap being formed with a grooved bar, and an eye bolt mounted in the bore of said projection, the eye of said bolt receiving said grooved bar,

five cents each, by addressing the Washington. D. 0.

whereby twine passed through the eye of said last named eye bolt will be yieldingly held therein by engagement with said bar.

3. A twine cutter, including plates, a cutter held between said plates, an eye bolt carried by one of the plates, the other plate being formed with a projection having a longitudinal bore, a cap slidingly mounted on the outer end of said projection, an eye bolt mounted in said bore, the cap being formed with a grooved bar extending through the eye of said last named bolt, and means tending to move the cap outwardly on the projection.

4. A twine cutter, including a body portion, a cutting element carried thereby, an eye at one end of the body portion, an eye at the other end of the body portion, a cap mounted on the last named end of the body portion and formed with a bar passing through the last named eye, and means tending to move the cap outwardly on the body portion so as to clamp between the bar and said eye, the twine passed through the latter.

5. A twine cutter, including a pair of plates, a cutting blade clamped between said plates and formed with peripheral cutting notches, one of said plates being formed with a projection, an eye carried by said projection, the other plate being formed with a projection provided with a longitudinal bore, an eye bolt adjustably mounted in said bore, a cap slidingly mounted on the outer end of said last named projection, and a spring mounted in said cap and tending to move it outwardly on the projection, the cap being formed with a grooved bar passing through the eye of the eye bolt, for the purpose specified.

In testimony whereof I hereunto'affix my signature in the presence of two witnesses.
