Another object is the manner of use when cutting said material with a tool according to the Invention.

Another object is to cope with different situations with the tool according to the invention, namely in those cases where an edge of a table or the like is not required, the tool also being used for cutting Mica is suitable in the absence of a table edge as well as for cutting mica or plastic, especially in regards to on the need for different methods of cutting mica versus plastic.

Another object is to provide a tool for cutting irregular cuts at the same time and / or holes.

Another object is to create a tool with a multitude of interrelated and reciprocal Related uses when machining flat surface mica and / or plastic materials.

509823/0465

Other tasks arise from both the foregoing and also from the following remarks.

One or more of the named tasks are carried out by the invention described below solved.

The invention broadly relates to a cutting tool and its mode of use, the cutting tool consisting of an elongate body with a head in which a slot is formed which extends from the free end of the head backwards towards the handle part. And as essentially Flat slot is formed, the head having a stop on its back against which the edge of a table strikes when the tool slides, in such a way that the edge of the workpiece, for example the edge of a mica plate, slides in the slot. The head has a downwardly extending, removable needle which extends downwardly through an upper projection of the head at a point where the needle is substantially aligned with the end of a lower head stop, the head stop normal against a table edge abuts the downward .. needle whereby the Micamaterial at a point scribing or cutting into the surface of which is flush with the ^T ical, with the head of the lower stop projection comes to rest after the upper surface by lateral reciprocating Movement of the stop head 'has been scratched.

Downward pressure is applied to the incised edge of the strip used to break off the mica strip. Extending further back from the handle portion is angled downwardly and rearwardly directed rear projection provided which has a hole at its rear end which extends axially in the rear projection and receives a removably attachable pin. The back pin can be used to cut mica by turning the hand tool in the hand, if a jish edge is not is available or desired. The tool is then guided along a straight edge, with the back the mica material is scored about 5 or 6 times so that the material is cut about halfway, and the thumb continues to apply downward pressure along the cutting line, while the other hand touches the part of the mica breaks up behind the incised edge. On the other hand, cutting plastic is the same way of working used with the exception that it is cut downwards. For cutting out irregular cuts and holes the rear pin is used, using a template or punch template. It will then be 8 to Incised 10 times so that the pin cuts through the material to be cut up to 3/4 of its thickness, with the the back of the material to be cut is printed to break out the scored section. This will sharpen the pin on the rear projection

The invention results in a very suitable new tool for easily cutting mica (iron glass »mica), ceiling plastic material, sheet material made of plastic, vinyl, tiles, tiles or the like. It is within the scope of the invention that the shape of the tool can vary very considerably from one embodiment to another, provided that the basic elements of the construction of the tool according to the invention are given. These elements consist of a lower stop protrusion as part of the head, an upper overhanging head protrusion with a needle directed downwardly from the head protrusion and removably secured therein such that the cutting point of the needle is closely adjacent and aligned with the Stop end of the lower head projection. It is noteworthy, however, that the preferred embodiment illustrated in Figures 1 through 5 is a particular and highly useful embodiment because of the strength of a cutting tool of this particular construction, along with the ease of handling and handling the tool and achieving the desired results Cutting effects,

509823/0465

the rapid availability of the additional cutting end on the rear, downwardly extending projection of the tool must be viewed as a relief of the cutting function of the tool.

Referring to the figures, Figure 1- shows in detail the cutting tool 6 in a preferred embodiment with an inner recessed surface 7, which is shown in FIG on opposite sides of the cutting tool, this surface 7 being replaced by thicker, reinforcing handle members is surrounded. It is emphasized that the recessed areas together with the strong, thickened peripheral areas, who carry the lower and upper protrusions of the head and the rear, pin-holding protrusion, a better opportunity provides for the person handling the tool to hold the tool appropriately without the tool being able to has to slip and / or slip out of the person's hand and / or turn in the hand. Of the The head of the cutting tool includes a lower head protrusion 8b and an upper head protrusion 8a which are mutually along the imaginary longitudinal axis of the cutting tool 6 extend forward, the upper projection 8a and the lower projection 8b together.mit the rear 'area of the head form a stop slot 8 of predetermined length and width, the structure and shape typically are shown and give sufficient space for the mica or plastic plate, which is slidably inserted in the slot.

509823 / 04S5

That is, the tool is moved towards the edge of the plastic plate such that the edge is inserted into the slot until the lower projection 8b with its flat end surface abuts against the supporting side of a table below the plastic plate 18a, the needle 10 is inserted into the hole 9 pointing downwards and is fastened in the desired position by a screw 12, the screw 12 being inserted into a threaded hole 11. The shaft of the screw 12 comes to rest against the needle 10 located in the channel formed by the hole 9 and presses it firmly. At an opposite end of the cutting tool, a scratching part is provided, which can be used together with the cutting head in a special cutting operation or spinning method to achieve uniform effects. The rear projection 13, which extends angularly downwards and backwards, has along its axis directed downwards a hole in a channel 14 with a downwardly directed, fixed needle 15 which is secured by a fastening screw. Is set 17 in the desired position, wherein the S _c hraube engages in the threaded hole sixteenth

In a typical work case where both the head end and the back scoring end of the tool are used, You can make the initial scratch marks on the surface of a mica or plastic sheet using a ruler can be made, for example, as illustrated by the method of operation shown in FIG. For example, the ruler 20 with the left hand of the worker held in position while the

509823/0465

right hand of the worker grabs the cutting tool 6 in such a way that the scoring needle 15 against the supporting ruler 20 is held, whereby the needle is prevented from sliding backward, while the backward pressure by a downward pressure on the ruler during the back and forth movements of the cutting tool is compensated, whereby the The needle scratches the surface to be cut along the straight edge of the ruler 20, the ruler on the substantially flat surface 18 rests. After the initial scoring, the plate can be moved further outwards to to protrude so far opposite the table edge that the stop end of the tool against the underside of the table to rest comes when the needle 10 is aligned with the site to be cut. Complete further scratching activities the necessary scoring before the downward breaking movement of the tool 6 begins to break off, of the incised, protruding strip when working with mica material or before the after upward breaking movement begins, as shown in Figure 4, when working with plastic material. Accordingly, the opposite ends of the tool serve to maintain smooth operation and are. part of the overall combination for a particular work activity that depends on the particular task being performed should be depends. The depth or protrusion of the needle, 10 is adjustable.

509823/0465

In a conventional normal situation, however, the scribing operation shown in Figure 3 is typical of a Score when a section of mica material has been scored should be used without taking advantage of a table edge, or if the scratching activity is not in connection with a .Table edge is carried out, such as when performing a scratching activity for irregular cuts and / or holes for a special pattern. In such cases, for example, as indicated in Figure 3, the plate is normally used turned with the back side up and the ruler or the cutting pattern template or the like to guide the Needle 15 placed over it, and the underside or the back of the mica plate or the plastic plate is then by means of the Scoring needle 15 scratched, and after the mica material is scored in this way, the operator brings their thumb near the cut or score and exerts a downward pressure while the other hand of the worker presses the mica part to be removed, whichever is closest to the person behind the incised line breaks away at the top. When cutting the mica material through a pulling movement of the cutting needle 15 becomes the pulling movement running parallel to the direction of the ruler together with continued downward pressure until the needle cut about half the thickness of the mica material has j. after which, while with the thumb one hand down is pressed, the other hand executes an upward breaking motion to remove the material to be cut

section to remove.

Where such an activity indicated in Figure 3 is carried out with plastic material, normally the underside of the plastic is cut, the section to be broken off is broken off downwards after the cutting activity «The direction Breaking away is important to get a clean smooth edge in the To get the moment of breaking away. After breaking away the removed part made of mica or plastic material, it is possible to Complete this activity by using sandpaper, a file or the like to get a clean to give a smooth finish.

In a similar way, a conventional normal work activity is shown in FIG. 4 in which the mica material is not is pre-scored in the manner indicated in Figure 3, but the mica material is with its upper surface upwards and placed with its lower surface on the table or a workbench surface in the manner as Figure 4 shows, and the Scoring activity is begun and continued until about ten to twelve reciprocations of the needle are about one-half the thickness of the mica material, after which a downward pressure on the rear end of the instrument (Tool) the area to be removed, which is adjacent to the incised cutting line, is broken off. In in the same way, after breaking away with a piece of sandpaper, a file or an equivalent -

for smoothing and / or finishing the surface (the cutting edge) into a desired and finished State to be brought.

Figure 5 shows a typical method for sharpening the needle 5, the appropriate direction of movement for sharpening on a rough Surface of a file is shown.

Although a particular width, height and length of the instrument (cutting tool) according to this invention in a preferred embodiment S shape shown in Figures 1 to 5, it is within the scope of the invention, e.g., the width of the tool which would, in fact, reduce the possibility of the instrument moving sideways during back and forth Floats twisted sideways; or that the size of the handle part or the length of the instrument is increased or that some other changes may be made in the size and thickness of the slot, including such changes and / or modifications and / or equivalent changes may be made to the extent that this is obvious to a person skilled in the art technical area. It is emphasized that the pin 10 does not necessarily need a sharpening and on works best if it is not sharpened after use.

In some cases it is desirable to cut the plastic material with the needle 10 before the needle 15 on the
