Description

The proposed cutting wedge, intended for inserting it into the cutting behind the saw, in order to prevent it from clamping when cutting wood without the usual use — this separate plates of different thickness represent a single body made in the form of a sickle with a gradually increasing blade.

In FIG. 1 shows the appearance of a wedge; FIG. 2-oddy: from its cross sections; FIG. 3 - cha, stichny view from the blade; FIG. 4 - wedge usage method.

The proposed wedge has the form of a sickle (Fig. 1) equipped with handles at both ends. The heart blade has, but the entire length, a cross-section of the shape shown in FIG. 2, but with the thickness of part a increasing from one end to the other, the thickness being the same in elements b, b, with a difference from one to the other, approximately by 0, 5 mm, and in intermediate places in, in part a, the blades have non-parallel arms, and its thickness increases by 0.5 mm gradually from one element b to another. Thickness

Blades in places b, b are made according to the usual caliber of saws in 2 - 2.5--3, etc., up to 6 mlg.

The wedge is inserted into the saw blade (Fig. 4) with a thin end and pressing one of the handles up to the stop into the kerf of the element b with a thickness corresponding to the saw and, in addition, is fixed in it at least with a weak blow to the wedge-shaped rim of the blade, which also serves for wide cuts.

The subject of the invention.

1. Cutting wedge, characterized in that it has an arcuate shape with a blade that gradually thickens from one end to the other in areas in the form of elements b, b of equal thickness with transitions from one to another in places c, c using inclined to each other The cluster, which the wedge is intended for Lvod in the sawn behind the saw with its part that corresponds to the width of the cut.

2. In the wedge io p. 1, use on the back of a common wedge-shaped rim for very wide cuts.
