Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper cutting tool, and more particularly to a tool for cutting the wrapping paper of a coin package roll.

Coin wrapper cutting tools known from the prior art include US Pat. No. 4,106,196 (Smith-
A tool of the type that cuts a coin roll wrapper lengthwise from one end to the other, as exemplified by U.S. Pat. No. 3,781,987 (Gentscheff); There is a type in which the roll is torn in the circumferential direction on the circumference of the side wall of the roll, preferably near the end of the roll so that the wrinkled part of the end can be cut off.

The present invention constitutes a new and improved coin wrap cutting tool of the type that cuts the wrap circumferentially near one end of a coin roll.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a new and improved tool for facilitating the opening of coin package rolls without the need for tear strips or tear holes in the wrapping paper and without the hassle of tearing the wrapping paper. Our goal is to provide the following.

Another object of the present invention is to provide a new and improved tool for cutting the wrinkled ends of coin rolls without catching or damaging the coins.

It is also an object of the present invention to provide a new and improved coin wrap paper cutting tool in which the cutting blade is typically covered to prevent injury to the person using the tool.

It is a further object of the present invention to provide a new and improved cutting tool that is easily adjustable to accommodate rolls of coins of various sizes.

Other objects and features of the present invention will become apparent from the following description in conjunction with the accompanying drawings.

Referring in detail to FIGS. 1 and 3, the invention illustrated herein includes a combined base or body portion 12.
It has a device in the shape of a blade 14 for cutting off the wrinkled end of the wrapping paper of the coin package roll R, and a device in the shape of a sliding plate 16 to cover the blade 14 when not cutting. It will be appreciated that the present invention relates to a coin wrapping paper cutting tool 10 that is constructed of Base or main body part 1
2 includes shoulder 1 located at a distance from each other.
8 are included, respectively cutting blade 14 and blade 14
It supports a shield 16 that normally covers the body so as not to expose it to the outside. Each shoulder 18 has a side 20 from which a cutting blade 14 projects. The base or body portion 12 is provided with a platform portion 22 extending from a rear side 24. When the wrinkled end of the coin package roll R is to be cut, it is pressed against the contact surface 26 of the platform part 22. This contact surface 26 extends generally parallel to the shoulder 18 and the cutting blade 14, but as clearly shown in FIG. This contact surface 26 is closer to the cutting blade 14 by an amount that facilitates cutting of the wrinkled edges of the wrapping paper of the roll R.
near the base or rear side 24 of the main body 12.

The platform section 22 has a grooved or undercut passageway 28 formed between the contact surface 26 and each shoulder 18 for receiving the end of the wrapper cut off from the coin package roll R. It's getting old. 16 shields each
includes a cover surface 30 overlying the cutting blades 14 and a fence portion 32 that generally extends from each cutting blade 14 toward the cover surface 30. A retaining device in the form of a pin 34 moves from the shoulder 18 to the shield 16 to maintain the cutting blade 14 in the cutting position.
It is growing to. Each shield 16 is formed with a large hole 36 through which a retaining screw 38 extends to the base 12 to secure the shield 16 on the base 12 and allows the shield 16 to be attached to the cutting blade. 14 can be moved between a position covering and a position not covering. A parallel device in the form of a coil spring 40 is positioned to push against each retaining screw 38 and is located within each large hole 36 to bias the shield 16 into its normal cover position over the cutting blade 14. The grooved or undercut passageway 28 and the adjacent shoulder 18 are located far from or opposite the contact surface 26 so that the pair of cutting blades 14 and shield 16 are located on the shoulder 18 and are symmetrical to each other. It's summery.

As shown in FIGS. 1 and 2, the shield 16 is angled such that each fence portion 32 thereof widens from a generally closed rear end 42 toward a diffused entrance portion 44. , insert the coin roll R with its end pressed against the contact surface 26 and its side against the fence portion 32, and move the coin roll R toward its nearly closed rear end, as indicated by the arrow in FIG. When the shield 16 is retracted by pushing the spring 40 in the direction, the cutting blade 14 comes out and performs the cutting operation. As can also be seen in FIG. 4, the cutting blade 14 is generally parallel to the contact surface 26 and extends therefrom a distance approximately equal to the thickness of the crumpled closed end of the wrapper of the coin package roll R. Because the coin is supported on the shoulder 18 in the same position as when the crumpled end of the wrapper is cut, the coin will not be damaged by being nicked or scratched, and the blade 14 will not be damaged. do not have.

Each shield 16 includes a cover surface 30 and a large hole 4.
8 is provided with a plurality of guide members 46,
Each shoulder 18 also has a plurality of large holes 50 formed therein. When assembling, the guide pin member 46
into the large hole 50 of the shoulder 18, the holding pin 34 is passed through the large hole 48 of the shield 16, and the holding screw 38 is passed through the large hole 36 to set the position where the shield 16 covers the blade 14 and the position where it does not cover the blade 14. During movement therebetween, the large holes 50, 48, and 36 cooperate to receive the guide pin member 40, retaining pin 34, and retaining screw 38, respectively.

Each blade 14 has a plurality of notches 52 on its back edge.
is attached.

One of these cuts 52 is formed in the hole 5 in the shoulder 18 when the blade is assembled into the cutting tool 10.
3 and the large hole 36 of the shield 16. Each retaining screw 38 passes through the large hole, notch 52 and hole 53 to tighten the blade 14 and shield 16 to the base 12. An undercut seat 56 is formed in the shoulder 18 to accommodate the blade 14. In order to maintain constant contact between the spring 40 and the retaining screw 38, collar portions 58, 58 are integrally formed on both sides of the tapered diameter portion of the handle of each retaining screw 38. A spring 40 is in anchoring contact with the tapered portion of 38.

Coin roll R using the cutting tool according to the invention
To remove the contents, simply place the crumpled end of the roll R that closes the roll package at the entry point 44 onto the contact surface 26; When the side of the roll R comes into contact with the fence parts 32, 32, the fence part 32 presses the springs 40, 40 in the direction shown by the arrow in FIG. It is only necessary to move the roll R in the direction of the almost closed rear end 42 until the roll R is pressed firmly against the blade 14,
Roll R is rotated about its axis with the wrinkled end on contact surface 26, thereby removing the coin from roll R without catching or scratching it and without damaging blades 14,14. The wrinkled edges of the packaging can be cut off.

It will be obvious to those skilled in the art that various changes can be made without departing from the scope of the present invention, and the present invention is to be considered limited to what is shown in the drawings and description of the specification. Shouldn't.
