Description

Wynalazek dotyczy cyrkla, w którym kreslaca nózka, obracajac sie okolo nóz¬ ki centrujacej, moze byc zapomoca rucho¬ mego jezyczka przesuwana nazewnatrz, od¬ powiednio do spirali, jaka nalezy wy¬ kreslic. Jezyczek mozna równiez ustawiac, chcac regulowac skok spirali.The invention relates to a caliper, in which the sharpening leg, when pivoting about the centering leg, can be by means of a movable tongue that is moved outwards, corresponding to the spiral to be drawn. The little pin can also be set to adjust the pitch of the spiral.

Rysunek przedstawia przyklad wyko¬ nania wynalazku.The drawing shows an example of an embodiment of the invention.

Na górnej czesci a kreslacej nózki moz¬ na przesuwac sanki wodzikoWe b i ustawiac zapomoca gwint cwanego trzpienia c; trzpien jest polaczony z glówka d i zabezpieczony od przesuwania zatyczka / i wpustka pier¬ scieniowa e. Trzpien c mozna unierucho¬ mic srubka g, umieszczona w czesci a. Z san¬ kami b jest przegubowo polaczony jezy¬ czek h, który opiera sie o wyskok m nózki centruj acej. Zapomoca srubki nastawnej k, umieszczonej na sankach b, mozna bardziej lub mniej rozeprzec jezyczek h. Obydwie nózki cyrkla a i i sa polaczone zwojem spre¬ zynowym /, który sciaga obydwie nózki a i i przy kresleniu spirali, a przy kresleniu kól moze byc wylaczony.On the upper part a of the pointed leg, you can move the sledge sledge b and adjust it with the help of the thread of the pin c; the pin is connected to the head d and is secured against sliding, the plug / and the ring key e. The pin c can be fixed with a screw g, placed in part a. The sledge b is articulated with the tongue h, which rests on the spring m of the centering leg. Using the adjusting screw k, located on the sled b, you can more or less spread the tongue h. Both legs of the compass a and i are connected by a spring coil / which pulls both legs a and i when drawing the spiral, and when marking the wheels it can be turned off.

Dzialanie cyrkla jest nastepujace: Stosownie do skoku spinali, ustawia sie jezyczek h zapomoca sruby k blizej lub da¬ lej od sanek b, tak, aby jezyczek h, przy przesuwaniu sie ku górze, predzej lub wol¬ niej mógl rozpierac nózke kreslaca.The operation of the compass is as follows: According to the stroke of the clamps, position the tongue h with the screw k closer or further to the sled b so that the tongue h, when moving upwards, sooner or slower, can expand the drawer leg.

Jezeli kreslac obraca sie glówke c/, a rów¬ noczesnie nózke a okolo nózki i, to trzpien gwintowany c przesuwa sanki b wraz z je¬ zyczkiem h do góry, wskutek czego nózka kreslaca a stale sie oddala od nózki cen-trujacej i i kresli spirale. Dzieki dzialaniu sprezyny / otrzymuje sie równy kontur spirali.If the drawing head turns the head c /, and at the same time the leg a around the leg i, then the threaded pin c moves the sled b with the tongue h upwards, as a result of which the drawing leg a constantly moves away from the center leg and draws the spirals . Due to the action of the spring, an even contour of the spiral is obtained.

Gdy kresli sie kolo, ^amocowuje sie nieruchomo trzpien gwintowany c sruba g, i wylacza sprezyne h tak, ze mozna, oby¬ dwie nózki cyrkiaf latwo ustawiac. Nózki cyrkla mozna równiez ustawic zapomoca jezyczka h i sruby nastawnej k, przyczem sprezyna / moze zostac w polozeniu nary- sowanem. % a s t r%re zeaiia patentowe.

The legs of the compass can also be adjusted using the tongue h and the adjusting screw k, with the spring / it can be drawn in its position. % a s t r% patent documents.
