Groove plane with wooden screws and patented special iron holder. Top edges are slightly rounded, with line decoration. The plane: a slot at the top center for the depth setter 35x5 mm with an inset slot iron. The right side in the middle is 2 cm deep, 12 cm long at the top and 3.8 cm at the bottom, cut out in a triangle. The rear cut holds the iron holding device. In the center of the cutout is the bronze wing screw for clamping the depth stop. The 4 cm wide part of the plane is cut out at the bottom, 1.2 cm wide and 2 cm high, with the two-part 3 mm iron tongue 43 mm high and 249 mm long screwed to the side. The patented iron holder consists of a 145 mm long U-shaped iron piece, 21 mm wide on the outside, 15 mm on the inside (web 3 mm thick). The side webs are only 80 mm long, 9 mm high at the bottom and top, and 26 mm in the middle. At the top, the 15 mm wide sole of the U-iron continues for 66 mm with a 55 mm long, 5 mm wide slot. At the ends of the slot, there is a 15x12x7 mm lug with a 6 mm hole welded on both the top and bottom at the rear. In it rotates a 90 mm long, 6 mm screw, thread METRIC 60° DIN 13/14 1.25, which is pivotally riveted at the bottom. It runs on a 10 mm cube with a 6 mm threaded hole, a 5 mm guide in the slot, and a 6 mm long, 4 mm pin that guides the wedge and iron. An iron wedge 100x14 mm, 4 mm thick at the top tapering to 0 at the bottom with three 5 mm holes for adjusting higher or lower and thus setting the clamping strength. This lies under the planer blade. Between the rounded sides at the bottom, held with a screw, lies a 73 mm long, 14 mm wide toggle lever. It is angled at the bottom and has a 6 mm wide longitudinal slot with a bolt at the top where the 74 mm long curved eccentric lever holds. Pushed upwards, this clamps the planer blade. The depth setter 150x20x5 mm with a 4 mm side cutout and a vertically welded slot plate 34x5x100 mm. The left inside has two 2 cm holes in which the wooden adjusting screws of the side stop are fixed. These are 21.5 cm long with a 1.4 cm thread (diameter), 2.1 cm outside, 1.8 cm thread pitch 2.8 mm. Adjusting nut (diameter) 4.4, 1.2 cm wide (one is missing) recessed in the stop. Clamping nuts length 4.8 cm (dimensions 4/3/3.8 cm). Screw finish with a beautiful cone and ball head. Side stop: 25.6x2.6/5x10.5 cm with two 2.2/4.6 cm drillings.
