UNITED STATES PATENTIOFFICE.

ERWIN R. JONES, OF COLUMBUS, OHIO.

TWINE Application filed May 2,

To all whom, t may concern:

Be it known that I, ERWIN R. JoNEs. a citizen of the United States," residing at Columbus, in the county of Franklin and State of Ohio, have invented .certain new and useful Improvements in Twine Cutters, of which the following is a specification.

The present invention is directed to improvements in twine cutters.

The primary object of the invention is to provide a device of this character so constructed that twine can be conveniently-'severed when the device is resting'upon the counter or the like or it can be easily manipulated for severing twine upon packages of such weight as to not be conveniently lifted..

A further obj-ect of the invention is to provide a device of this character constructed in such manner that the cutting blade can be conveniently manipulated to cut pasteboard containers or the like, thereby providing a combination twine cutter and container opener.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a side elevation of the device,

Figure 2 is a longitudinal sectional view therethrough,

Figure 3 is a sectional view on line 3-3 of Figure 1,

Figure 4 is a sectional view on line 4-4 of Figure 2,

Figure 5 is a fragmentary longitudinal sectional view showing the cutting blade in its extended position,

Figure 6 is a detail perspective view of the cutting blade and its associated block.

Referring to the drawing 1 designates a base having a vertical post 2 rising therelfrom, said base being capable of being fixed to a counter or the like if desired. A hollow metallic handle 3 .is employed and has its lower end formed with a socket 4 for detachable engagement with the post 2, whereby the handle can be quickly removed or replaced; The handle 3 has cast therewith a sleeve 5 and transversely spaced vertical lingers 6 and 7 there being a longitudinal groove 8 formed in the inner face CUTTER.

of the linger 6 and which terminates in a groove 9 in the collar 5, said collar` being further provided with an annular .shoulder 10, the purpose of which will appear later. Also'cast with the collar 5 are spaced we bs ll which terminate in vertical spaced guide plates 12, the upper ends of which are curved as at 13.

The .cutting blade 14 includes a base 15 which normally rests on the shoulder ln and is formed with a recess 16 for slidahlyY neceiving the clamping block 17.v said block having spaced end wings 18 which embrace the adjacent parts of the base 15, This block `has a threaded bore 19 in which is engaged a thumb screw 20. Thus it will be seen that when the blade is in its assembled position that the back of the block and wings will engage the inner wall of the col- ,lar 5 and when the thumb screw is turned inwardly the end thereof will-be impinged against the base of the recess 16 thereby forcing the block outwardly into the frictional engagement with the collar and the back of the plate in tightJ engagement with 'the bases of the grooves 8 and 9, thereby vholding the blade againstaccidental movement. To accommodate the screw 20 a slot 21 is formed in the collar 5 and extends into the adjacent finger 7.

The cutting edge 22 of the blade for a major distance of its length is received in the space between the plates 12 so that when the twine to be severed is forced between the plates and blade it will be guided directly to the cutting edge of the blade and severed.

move accordingly, the outward movement thereof being limited when the screw engages the outer end of the slot 21, after which the screw is manipulated to clamp the block with the finger, thereby holding the blade firmly. In this manner the blade is so positioned, as shown in Figure 5 that a per son can conveniently grasp the handle 3 and .use the blade for cutting open paper containers or cartons. Of course when the dethe fingers, a cutting blade slidable between v the plates, and means for sliding and locking the blade in adjusted positions with respect to the fingers.

2. A device of the class described comprising a base, a handle removably mounted on the base', said handle having an annular shoulder formed therein, a pair of fingers associated with the handle, spaced .4 plates carried by one of. the ngers, a blade slidably mounted between vthe lingers and having its cutting edge slidable between said plates, and means for sliding the blade to an extended position with respect to the Viingersand locking the same in such posi-l tion.

- 3. A device of the cla-ss described comprising a handle, af blade slidably associated with the handle, means and other meansassociated therewith to force said blade and saidsecond named means in opposite direc-` tions into clamped engagement with the handle. v- Y blade with respect to the handle.

-4. A device 'of the class described comprising a handle, a blade slidably associated with the handle, a block associated With the blade, and means carried by the block for moving the same and the blade in opposite directions into binding engagement with the handle.

f 5. A device of the class described com; l

prising a handle, a pair of spaced plates xed interiorly of the handle and constitut ing a linger, a cutting blade slidable betweenl the plates, and lmeans for sliding and locking the blade in adjustable positions with respect to the handle.

6. A device of the class described comprising a handle,

fixed interiorly of the handle and constitut- 'ing a finger, a cutting blade associated with the plates and means .for locking the'blade with respect to the handle.

7. 'A device of the class described comprisinga handle, a pair of spaced plates fixed interiorly of the handle and constituting a finger, a cutting blade fixed between the plates, and means for locking the blade with respect to the handle.

8. A device of the class described comprising a' handle, a finger on the handle, a pairof spaced plates associated with said handlefand inger, a cutting blade fixed between the plates, and means for locking the .In testimony whereof I aiix m'y signature.
