Betrvr splitting hammer.

Until Bringing; concern a splitting hammer. For splitting plywood, a hamiaer used. SLe "previously used splitting hammer have a narrow cutting edge ^ are heavy (up to 3 and a large grinding angle (25 to 3o ° 5 Splitting hammers used are intended to split the plywood due to their high weight with one. Cut deep enough into that Penetrate wood and at the same time push the wood fiber with its large cut angle far enough apart, so that the wood then splits »

Both tasks are fulfilled by the currently common Spalthammer not jsdoch * The weight of the hammer gap right ^ to: deep penetration to cause * The cut = angle up to 3o ° However, only good for smooth em, knot-free, so easily fissile wood. With knotty, Overgrown or even frozen wood, turns out that the existing gap = "hammer in their J? Ona are still unfinished as they penetrate too little or not at all to that. Splitting wood, ^ ewx to the Schliifwinkel If, on the other hand, it was designed more slenderly, the splitting hammer would penetrate deeper, but get stuck (bite tight) »so that one would have no way to get it out of the wood; however, the slimmer bevel would also mean that it would lose its ability to keep the wood fibers apart again.

The invention now brings a considerable terbes = Solution by the fact that on the actual cutting edge of the gap = hammers. a cutting edge that is approx. half slimmer is set. This slender torso tendon penetrates more easily due to its cut angle of only half the size of 12 to 15 °

BIO 7526 M in the ax-splitting wood «Ein. Easier penetration is achieved by its almost 50 # shorter cutting length compared to the actual cutting length of the splitting hammer. The length of this pre-cutting edge is about 2.5 to 5 cm. Working with a splitting hammer constructed in this way on overgrown and frozen wood has brought the desired success »This short, slim precutter penetrates comfortably into any wood and shows a slight scratch the same work step for splitting the wood. A setting of the splitting hammer cannot take place in this way, since the 'larger grinding angle releases the gate cutter with the smaller angle again. In the drawing, the invention is shown in an exemplary embodiment. Fig.X shows the side view of the splitting hammer, Pig.II, on the other hand, the top view. The handle 1 is fastened in the holder of the house 2 of the splitting hammer 3, which thickens in a known manner on one side like a hammer 4 for driving in splitting wedges, while the opposite side is slim and wedge-like 5 tapers to the actual splitting. In front of this larger cutting edge 6 with. The pre-cutter with the approx. Sehutz claims: 1. Splitting hammer, characterized in that before the actual Cut surface a second cut surface as a pre-cutter is superior 2. gap chamber according to claim!, Characterized in that the Cutting length of the gate cutter is about half as long as the actual cutting length. 3 · Splitting hammer according to claims 1 and 2, characterized in that the pre-cutter has a grinding angle approximately half as large as the grinding angle of the actual cutting surface.
