Description

Przyrzad sklada sie z ruchomych tasm stalowych, Konstrukcje przyrzadu uwi¬ docznia zalaczony rysunek. Punkty c i d sa nieruchome, natomiast punkty a i 6 sa ruchome i poruszaja sie w prowadnicach c—/ i d—g.Sposób uzycia aparatu jest nastepuja¬ cy: na kat, który ma zostac podzielony, naklada sie przyrzad w ten sposób, by kat aob przystawal do tego kata, co daje sie osiagnac przez rozszerzenie lub zweze¬ nie kata feg. Wówczas otrzyma sie katy aoh, hoi i 106, z których kazdy stanowi jedna trzecia czesc kata aob. Otwory prowadnicze w linj ach ao, oh, oi, ob po¬ zwalaja olówkiem nakreslic owe poszu¬ kiwane katy.Istota wynalazku polega na polaczeniu poszczególnych czesci przyrzadu w ten sposób, ze zgodnie z powyzszym opisem umozliwione jest dzielenie jakiegokolwiek kata na 3 równe czesci.Przyrzad do dzielenia katów na 3 cze¬ sci umozliwia dokladne dzielenie wszel¬ kich katów na trzy czesci, dzieki temu, ze katy a—o—h, h—o—i i i—o—6, stano¬ wiace kazdy jedna trzecia kata a—o—6, równe sa katom a—c—o, c—e—d, c—o— d, o—d—b, d—6—o i c—a—o, poniewaz odcinki a—o, c—o, c—e, e—d, d—o, i o— b sa równe pomiedzy soba, wskutek czego równosc katów zachowywana jest we wszelkich pozycjach przy zmianie wielko¬ sci kata a—o—b. PLThe device consists of movable steel strips. The structure of the device is illustrated by the attached drawing. Points c and d are stationary, while points a and 6 are movable and move in guides c— / and d-g. The method of using the apparatus is as follows: the angle to be divided is placed on the device in such a way that the angle aob stops to this angle, which can be achieved by widening or narrowing the angle of the feg. Then you will get kata aoh, hoi and 106, each of which constitutes a third of the kata aob. The guide holes in the lines ao, oh, oi, ob allow the pencil to draw the desired angles. The essence of the invention consists in joining the individual parts of the device in such a way that, as described above, it is possible to divide any angle into 3 equal parts. The device for dividing angles into 3 parts makes it possible to accurately divide all angles into three parts, thanks to the fact that angles a-o-h, h-o-iii-o-6, being each third of an angle a— o — 6, equal to sa angles a — c — o, c — e — d, c — o— d, o — d — b, d — 6 — oic — a — o, because the segments a — o, c — o , c-e, e-d, d-o, io-b are equal to each other, so that the equality of angles is maintained in all positions when changing the size of angles a-o-b.

Claims

1. Patent claim. Device for dividing angles into 3 parts, characterized by the fact that it consists of two movably connected steel tapes, with which two tapes are connected in a stationary way, and two tapes in a movable way, connected in turn Altogether movable with one common joint, all tapes have punched holes along their entire length, or parts of their length, serving as guides for the three movable joints of the device.
