Предлагаемый чертежный прибор ; редназначенный дл  , обучени  слепых черчению, дает возможность слепому в любом месте чертежа строить желаемый угол 1 проводить линии любого направлени .The proposed drawing device; Designed to train blind people in drawing, allows a blind person to build the desired angle 1 in any part of the drawing to draw lines in any direction.

На чертеже фиг. 1 изображает вид прибора сверху и фиг. 2-то же вид сбоку.In FIG. 1 is a top view of the device and FIG. 2 is the same side view.

Предлагаемый чертежный прибор состоит не прикрепленной к чертежной доске J4 посредством скоб 7 угловой линейки 7, снабженной направл ющими прорезами 77 и 75, соединенными между собой дуговым прорезом 72. При помощи этого прореза /2 по линейке 7 может непрерывно перемещатьс  рейсшина 5, 9, св занна  с транспортиром 2, путем продвижени  в прорезах 77, 72, 75 пальца 5, укрепленного в напрагзл ющей планке 5 рейсшины.The proposed drawing device consists of an angle bar 7, which is not attached to the drawing board J4 by means of brackets 7, provided with guide slots 77 and 75, connected by an arc slot 72. With this notch / 2 along the ruler 7 can be continuously moved connected with the protractor 2, by advancing in slots 77, 72, 75 of the finger 5, fortified in a striker plate 5 of the rail.

К означенной планке 5 присоединен транспортир 2, снабженный прорезом 6 дл  перемещени  по нему линейки 9 рейсшины, при помощи пальца 7 и, кроме того,-выступами 3 и углублени ми 4A protractor 2 is attached to the above bar 5, provided with a slit 6 for moving the rail strip 9 along it, with the help of a finger 7 and, in addition, with projections 3 and recesses 4
