Description

Предлагаемое изобретение- касаетс  приспособлени  к нивеллиру дл  отсчета вертикальных углов.The present invention relates to adapting to a leveling device for counting vertical angles.

Изображенное на чертеже приспособление состоит из доски 2, надеваемой на трубу нивеллира при помощи зажимных пружин 1. На этой доске имеетс  поперечный масштаб, и к ней прикреплена градуированна  рейка 3, по делени м которой ходит указательна  стрелка 7, составл юща  одно целое с коромыслом 5, лежащим на призме, утвержденной в головке стойки 4, укрепленной на доске 2. Коромысло уравновешиваетс  гир ми 6.The device depicted in the drawing consists of a board 2, which is put on the pipe of the nivellier by means of clamping springs 1. This board has a transverse scale, and a graduated rail 3 is attached to it, divided by an arrow 7, which is integral with the rocker arm 5 lying on the prism, approved in the head of the rack 4, mounted on the board 2. The yoke is balanced by the weights 6.

Приспособление надеваетс  на нивеллирную трубу и помощью микрометрических винтов приводитс  в горизонтальное положение так, чтобы стрелка на коромысле стала против делени  на рейке со значением 0. Когда установка выполнена, нивеллир навод т на п)едмет так, чтобы точка пересечени  волосков в нивеллире совпала с основанием предмета . После этого смотр т на рейку и отмечают на ней цифру делени  по указанию стрелки, котора , не тер   своейThe device is put on the leveling tube and is driven to the horizontal position by means of micrometric screws so that the arrow on the rocker arm resists dividing on the rail with a value of 0. When the installation is completed, the leveler points at n) so that the point of intersection of hairs in the leveler coincides with the base subject. After that, they look at the rail and mark the division number on it as directed by the arrow, which, without losing its

горизонтальности, автоматически отмечает тангенс угла превышени  над горизонтом , а следовательно, и превышеI ни  и понижени  одной точки местности по отношению к другой.horizontality, automatically marks the tangent of the angle of elevation above the horizon, and consequently, above and below and lowering one point of the terrain relative to another.

При движении нивеллира вверх, а вместе с ним и всего приспособлени , стрелка, остава сь все врем  в горизонтальном положении, будет откладывать тангенс угла по рейке от О книзу и наоборот, ибо рейка, будучи зажата винтом неподвижно под углом 90° к доске, даег одинаковые отметки тангенсов в ту и другую сторону.When moving the levelr up, and with it just the whole device, the arrow, remaining all the time in a horizontal position, will set aside the tangent of the angle on the rail from O to the bottom and vice versa, because the rail, being clamped with a screw motionless at an angle of 90 ° to the board, will give identical tangent marks in both directions.

Предмет изобретени .The subject matter of the invention.

Приспособление к нивеллиру дл  отсчета вертикальных углов, отличающеес  тем, что оно состоит из надеваемой при помощи зажимных пружин 1 на трубу нивеллира доски 2, снабженной поперечным масштабом и несущей закрепленные на ней рейку 3 и стойку 4, на которой на призме лежит несущее гирьки 6 коромысло 5 с указательной стрелкой 7, ход щей против делений рей1;си 3.Adaptation to the leveling device for counting vertical angles, characterized in that it consists of a board 2 worn with clamping springs 1 on the pipe of the nivellier, provided with a transverse scale and carrying a rail 3 attached to it and a rack 4 on which the bearing 6 carries a weight on the prism 5 with an indicator arrow 7 that goes against the divisions of re1; sy 3.
