Предлагаемый прибор состоит из неподвижной рамки Л и двух перемещающихс  друг относительно друга в двух взаимно - перпендикул рных направлени х пр моугольных рамок 12 и 13, перемещение The proposed device consists of a fixed frame L and two moving relative to each other in two mutually - perpendicular directions of the rectangular frames 12 and 13, moving

которых используетс  дл  копировки с натуры поперечных сечений лопастей пропеллера. Внешн   рамка 11 устанавливаетс  в требуемом месте на поверочном столе 1, который поддерживает на штыре 2 пропеллер -5. Неподвижна  рамка 1 несет валики 30 и 32 с перематываемой с одного из них на другой и прилегающей к доске 27 бумагою 33. Средн   рамка 12 направл етс  горизонтально в неподвижной рамке 11, а внутренн   рамка 13 направл етс  в рамке 12 вертикально и снабжена, с одной стороны, поворотными около осей 7 и закрепл емыми в требуемом положении зажимами 10, руко тками 9. Последние снабжены роликами на удлиненных част х, которые ведутс  по контуру выбранного на лопасти пропеллера поперечного сечени . С другой стороны рамка 13 снабжена зубчатой передачей 18, 20; из них колесо 8 имеет руко тку дл  его вращени . Колесо 20 несет эксцентрично расположенныйwhich is used for copying from life the cross sections of the propeller blades. The outer frame 11 is installed in the required place on the testing table 1, which supports the propeller -5 on pin 2. The fixed frame 1 carries rollers 30 and 32 with paper 33 being rewound from one to the other and adjacent to the board 27. The middle frame 12 is horizontally guided in the fixed frame 11, and the inner frame 13 is guided vertically in the frame 12 and provided with one swiveling around the axes 7 and fastened in the desired position by clips 10, handles 9. The latter are provided with rollers on the elongated parts, which are guided along the contour of the cross section chosen on the propeller blade. On the other hand, the frame 13 is equipped with a gear 18, 20; of these, wheel 8 has a handle for rotating it. Wheel 20 carries eccentrically located
