WAYS TO EXECUTE INVENTION

IN 1 and 2 schematically the machine according to the invention for sawing firewood is shown.

At the lower frame left and right ( 3 ) is the top frame ( 20 ) appropriate. On the front side of the left and right frame ( 3 ) are each a transport wheel ( 4 ) with the bracket and axle attached.

At the back of the left and right frames ( 3 ) are each an extendable transport tube ( 5 ) appropriate. On the front side of the frame ( 3 ) is from left to right the rotatable bearing ( 6 ) of the drum ( 1 ) appropriate.

In storage ( 6 ) the drum ( 1 ) with the drum shaft ( 15 ) rotatably mounted by means of ball bearings. On the lower half of the drum ( 1 ) are the slots ( 9 + 11 ) for the upper and lower hold-down ( 23 ) available. Between the slots ( 9 + 11 ) is the slot ( 10 ) for the saw blade ( 14 ).

On the upper half of the drum ( 1 ) is the drive ring ( 2 ) appropriate. Inside the drum ( 1 ) are completely through the drum openings ( 21 ) integrated in V-shaped form.

On the left side of the upper frame ( 20 ) is in the corner the storage ( 22 ) of the upper and lower hold-down ( 23 ) appropriate. The two movable hold-downs ( 23 ) by means of an axle in the storage ( 22 ) attached.

In the right corner of the upper frame ( 20 ) is the lock ( 27 ) of the shim ( 7 ) appropriate. In the lock ( 27 ) is the linkage with handle ( 8th ) for the shim ( 7 ) releasably secured with a screw or bolt.
