KI. 30g 6.Pomysl polega na tern, ze sztyfcik lapisowy, wlozony do gumowej rurki, usztywnionej cienka blacha, moze byc wysuniety przez pokrecenie nasadki na gwincie, o której spód opiera sie la¬ seczka z opartym na niej lapisem.Rysunek przedstawia podluzny prze¬ krój.Sztyft lapisowy a wsuniety jest do rurki gumowej c, usztywnionej cienka blacha srebrna b i nasadzonej jednym koncem np. na ebonitowa oslone d.W oslone te wsunieta jest luzno la¬ seczka e, dostatecznie dluga, aby mozna bylo sztyft lapisowy zupelnie wysunac.Grubszy koniec dl oslony d jest chro¬ powaty lub karbowany, aby ja lepiej utrzymac w reku, drugi zas równiez grubszy koniec posiada gwint o wiek¬ szej srednicy, anizeli srednica oslony d.Nasrubowana na ten gwint rurkowa na¬ sadka / na dostatecznie dlugi gwint we¬ wnetrzny, moze byc zatem znacznie do gó¬ ry przesunieta. O dno tej nasadki/opiera sie dolny koniec laseczki e, górny zas jej koniec dotyka dolnego konca sztyftu lapi¬ sowego, Jezeli wiec srubuje sie powoli nasadke/ do góry, to laseczka e wypycha lapisowy sztyft z gumowej rurki c.Nasadka / zaopatrzona jest jeszcze w gwint zewnetrzny do nasrubowywania nania ochronnej oslony, która na rysunku przedstawiona jest kreskowanemilinjami. PLKI. 30g 6. The idea is that a lapis stick, inserted into a rubber tube, a stiffened thin sheet of metal, can be ejected by turning the cap on the thread, the bottom of which rests a lamp with a paw on it. The drawing shows a long cross-section The lap stick a is inserted into a rubber tube c, stiffened with a thin silver sheet b and placed at one end, e.g. on an ebonite cover dW, the cover is loosely slid e, long enough so that the lapis stick can be completely extended. d is roughened or notched to hold it better, while the other, also thicker end has a thread of a larger diameter than the diameter of the sheath d. A tubular socket on this thread is screwed on to a sufficiently long internal thread, it can therefore be shifted significantly upwards. The bottom of this cap / the lower end of the stick e rests, and its upper end touches the lower end of the lap stick, so if you slowly screw the cap / upwards, the stick e pushes the stick out of the rubber tube c. The cap / is still fitted with with an external thread for screwing on the protective cover, which is shown in the figure with dashed figures. PL
