Description

Известны приборы дл  вычерчивани  конхоидальных кривых, выполненные в виде раздвижного стержн , составленного из двух частей, одна из которых одним концом подвижно монтирована на неподвижном шарнире, а друга  часть в середине снабжена обводным штифтом, взаимодействующим с неподвижной пр молинейной направл ющей, и на внешнем конце-шарниром, осуществл ющим движение заданной точки. При установке пишущего остри  вместо подвижного шарнира STOT механизм легко преобразуетс  в прибор дл  вычерчивани  вне1иней ветви конхоиды. Недостатком известных приборов  вл етс  то, что, пользу сь им, можно вычертить лишь внешние ветви конхоиды.Instruments for drawing conchoidal curves are known, made in the form of an expanding rod composed of two parts, one of which is movably mounted at one end with a fixed hinge, and the other part in the middle is equipped with a bypass pin cooperating with a fixed linear guide and at the outer end - by a hinge which moves a given point. When a writing tip is installed instead of the movable hinge, the STOT mechanism is easily converted into an instrument for drawing an out of one line branch of a conchoid. A disadvantage of the known instruments is that, by using them, only the outer branches of the conchoid can be drawn.

Описываемый прибор обеспечивает возможность одновременного вычерчивани  вненшей и внутренней ветвей конхоиды, дл  чего на стержне по обе стороны от обводного штифта укреплены два переставных пишущих остри .The described device provides the possibility of simultaneously drawing out the inner and inner branches of a conchoid, for which two adjustable tips are fixed on the rod on either side of the bypass pin.

На фиг. 1 изображена схема прибора; на фиг. 2-прибор в продольном разрезе.FIG. 1 shows a diagram of the device; in fig. 2-instrument in longitudinal section.

На схеме раздвижной стержень прибора составлен из части 1, вращающейс  вокруг неподвижного полюса 2 и подвижной части 3, снабженной обводным штифтом 4, перемещающимс  по направл ющей 5. Но обе стороны от обводного штифта укреплены два переставных остри  6 и 7, из которых острие 6, при переме1пении штифта 4 по направл ющей 5, вычерчивает внешнюю ветвь 8 коихоиды, а острие 7- внутреннюю ветвь 9. Раздвижной стержень прибора составлен из внутренней трубки 10, снабженной подпружиненным шарниром II с установочным острием 12, и свободно скольз щей по трубке 10 внешней трубки 13, вдоль которой монтированы три переставных хомутика 14 и 15, закрепл емые посредством винтов 16 и 17, взаимодействующих с желобком 18 на трубке 13. Хомутик 15 снабжен подпружиненным обводным штифтом 19, а хомутики 14-цангами 20 дл  креплени  пишущегоIn the diagram, the sliding rod of the device is composed of part 1 rotating around a fixed pole 2 and a moving part 3 equipped with a dowel pin 4 moving along a guide 5. But both sides of the dowel pin are fixed two adjustable points 6 and 7, of which point 6, when the pin 4 is moved along the guide 5, the outer branch 8 is drawn with co-yoids, and the tip 7 is the inner branch 9. The extension rod of the device is made up of an inner tube 10 equipped with a spring-loaded hinge II with an adjusting tip 12 and freely sliding along the pipes e 10 of the outer tube 13, along which are mounted three resettable clamp 14 and 15, emye secured by screws 16 and 17 interacting with the groove 18 on the tube 13. The clamp 15 is provided with a spring-loaded bypass pin 19 and clamps 14, collet 20 for securing the writing
