Abstract

A chisel comprises a shaft 3 to be held by a hand or power tool, with an angled edge 4, and with a leading cutting edge 7, a following edge 8, and a variable shaped face between 7 and 8 and a crosscutting scarifying edge 6. <IMAGE>

Description

CHISELS This invention relates to chisels.
Cnisels are well known tools that can be utilised for hand tools or power hammer tools, they are usually provided with certain type chisels for cutting, none of them I have observed are designed for a motion of simultaneously cross cutting while scarifying while chasing out or with at least one intermediate cross cutting edge opposed to and with variable frontal movement.
The present invention is concerned with chisels for cleaning out at least joints in existing materials.
There is now provided a design of chisels to deal with this motion.
According to this present invention it is designed with a shaft that may accommodate at least the hand, Sir, Hydraulic, Electric or any power tools, with at least one variable shaped cross cutting edge at a certain angle, that may have at least one variable shaped cutting or scarifying edge between the front leading edge and rear following edge, that will accommodate a certain joint.
It is preferred that the shaft may at least accommodate the hand, Nir, Hydraulic, Electric or any other power tools, and may have a certain width and shape to give enough material to allow for periodical sharpening, that may have at least one desired variable shaped angle of cut for cross cutting while scarifying while chasing out being variable opposed to and with frontal movement.
The invention will now be further illustrated by way of example only, with reference to the accompanying drawing, wherein: Figure 1 is a front view of the chisel according. to the present invention.
Figure 2 is a side view nf the chisel according to the present I nventi on.
Referring to figure t. The shaft 3 may be at least hand held or may accommodate at least one hand or power tool. The variable angle 4 draws the width to at least one certain angle from the shaft thickrlr?ss to accommodate at least one certain width joint gives enough material to allow for periodical sharpening, with at least one variable shaped intermediate scarifying or cutting edge 6, of which may allow for at least loosening er intr.?rmr.?diatrn cutting or scarifying, while the front cutting edge 7 with a variable angle between S leads in and sideways while crosscutting and chasing out in and through.

Claims (9)

Claims:
1. Chisels comprising of at least one shaft that could at least accommodate the hand, Rir, Hydraulic, Electric or any other power tools, that may accommodate widths of joint, that may have at least one variable shaped drawn angle +rom the shaft to accommodate a variable shaped width of joint, that may have at least one variable shaped leading cutting edge, and at least one variable shaped following cutting edge, with at least one variable shaped angle between the leading edge and foll QWi ng edge and to the shaft , with at least one variable shaped cutting or scarifying edge, with at least one variable shaped cross cutting edge being variable opposed to and with frontal movement.
2. Chisels comprising of a shaft according to claim i, that may accommodate at least hand or power tools.
3. Chisels according to claim 1 or 2, that may at least accommodate one variable width of joint.
4. Chisels according to claim 1 to 3, that may have at least one variable shaped drawn angle from the shaft.
5. Chisels according to claim 1 to 4, that may have at least one variable shaped cross cutting edge.
6. Chisels according to claim 1 to 5, that may have at least one variable shaped cutting, crosscutting or scarifying edye.
7. Chisels according to claims 1 to 6, that may at least simultaneously, cut, crosscut and scarify.
8. Chisels according to claim 1 to 7, with at least one desired shape to allow for certain joint sizes and allowance for periodical sharpening.
9. Chisels ffi according to claims 1 to 8, with at least one angle opposed to and with frontal motion or through and side chasing.
