Description

Предлагаемое изобретение касаетс  пантографа дл  увеличени  и уменьшени  чертежей или планов с применением двух поворотных вокруг общей оси штанг, снабженных пишущими приспособлени ми и перемещающейс  при помощи шнуров каретки. .The present invention relates to a pantograph for enlarging and reducing drawings or plans using two rotatable rods around a common axis, equipped with writing devices and moving with carriage cords. .

На чертеже фиг. 1 изображает вид пантографа сбоку; фиг. 2-то же, сверху.In FIG. 1 shows a side view of a pantograph; FIG. 2 is the same above.

На вертикальной конической оси 12, вращающейс  в подставке 1, укреплена штанга 2, имеюща  на своих концах ролики 3, 4 и 5, между которыми нат нуты шнуры 6 и 7.On the vertical conical axis 12, rotating in the stand 1, the rod 2 is fixed, having rollers 3, 4 and 5 at their ends, between which cords 6 and 7 are pulled.

Ролики 3 и 4 соедин ютс  между собой винтом, при чем ролик 4-сменный, что дает возможность при вращении ролика 3 или 4 перемещать шнуры на разномасштабные величины. На правом конце штанги 2 находитс  отросток, несущий на; себе ролик 8, служащий опорой дл  выдвижной штанги 9, другой конец которой лежит в роликах 13, установленных на оси 12. Штанга 9 снабжена на конце карандашом 10. Перемещение карандаша 10, св занного через штангу 9 со шнуром 1, вызывает перемещение роликовой каретки 11, св занной со шнуром 6. Таким образом соединение радиального масштабного движени  с пол рным дает возможность копировани  рисунков и карт в разных масштабах при наличии набора роликов 4.The rollers 3 and 4 are interconnected by a screw, the roller being 4-replaceable, which makes it possible to move the cords to different scale sizes during the rotation of roller 3 or 4. At the right end of the rod 2 there is a process bearing on; the roller 8, which serves as a support for the sliding rod 9, the other end of which lies in the rollers 13 mounted on the axis 12. The rod 9 is provided with a pencil 10 at the end. associated with the cord 6. Thus, the connection of the radial scale movement with the polar allows the copying of drawings and maps at different scales with a set of rollers 4.

Предмет изобретени .The subject matter of the invention.

Пантограф дл  увеличени  и уменьшени  чертежей, планов и т. п., состо щий из двух, поворотных вокруг общей оси, штанг и пишущих приспособлений, с применением каретки и шнуров дл  ее перемещени , отличающийс  тем, что в цел х перемещени  каретки 11 с пишущим приспособлением, нижн   штанга 9 с карандашом 10 сделана подвижной в направл ющих ролика 8, 13 и св зана с кареткой через шнуры 7, 6, перекинутые через ролики 3, 4, 5, укрепленные на верхней штанге 2.A pantograph for enlarging and reducing drawings, plans, etc., consisting of two, rotatable around a common axis, rods and writing devices, using a carriage and cords for its movement, characterized in that for the purpose of moving the carriage 11 with a writing the device, the lower rod 9 with a pencil 10 is made movable in the guide rollers 8, 13 and is connected with the carriage through the cords 7, 6, thrown over the rollers 3, 4, 5, mounted on the upper rod 2.
