Igisabo kinyeganyega gifite igikubita kizengurutswa n’umugozi uzinze: Kunyeganyega kuzamura igikubita, umugozi uzinze ukakizengurutsa uko kigenda

"Inkoni y’igikubita, E, ifite umurongo uzinze cyangwa umugozi wa vis, f, uyizengurutse, kandi ikorwa ku buryo yinjira cyangwa ikorera muri vis y’igitsina gore ihuye nayo, g, iri cyangwa ishyizwe ku nkoni yambukiranya, h, iri hagati kandi ifatanye n’inkoni, b, b, no mu irembo nk’uko bigaragara mu bishushanyo."

Capa sector rack, pinion, inkoni izinze ihagaze, isahani ya vis n’igikubita. Capa muri PETG ku byiciro bya mm 0.2, kuzuza 30 %, inkuta 4; byoze mbere yo kubikoresha bwa mbere.

Ubaka umurandasi uhagaze wa pine ugizwe n’imirandasi ibiri imeze nka A ifite uburebure bwa mm 600 hafi, ihujwe hejuru. Manika umurandasi unyeganyega wa pine ugizwe n’inkoni ebyiri zihagaze n’ikibaho cyo hasi ku nkoni za mm 10 zinyura mu mirandasi ya A, maze ushyire ikintu kibereye ibiryo gifite impande zigororotse hasi kuri wo. Fatisha sector hejuru y’inkoni imwe ihagaze, hagati ku nkoni yayo.

Fatisha inkoni yambukiranya hagati y’inkoni zihagaze isahani ya vis iri hejuru y’umwobo, n’irembo rya pine rinyerera hejuru yayo. Fatanya na kole inkoni za mm 10 ku mpera z’inkoni izinze, iyo hasi mu gikubita, maze unyuze inkoni mu isahani, hejuru hayo hazenguruka neza mu irembo. Shyira pinion ku nkoni y’inyeganyeza ya mm 10 ifite impande enye mu murandasi uhagaze, ihura na sector, maze uhuze ukuboko kuri yo n’irembo ukoresheje pitman ya pine.

Urupapuro rw’igishushanyo cya US 16,193, umutungo rusange (patenti yarangiye).

Reka amavuta y’amata afashe agere hafi kuri 15 °C, ugenzure na thermometre. Suka litiro 1.5. Nyeganyeza umurandasi uhoraho ukoresheje ikiganza cyawo; igikubita kirazamuka, kikamanuka kandi kikazenguruka. Bara igihe kugeza amavuta y’inka aje. Sesa ikivuguto, wongeremo amazi akonje, uvuge gato maze wongere usese kugeza bisohoka bisukuye; vangamo agace k’umunyu maze upime amavuta y’inka.

**Charles A. Shaw** wo muri Biddeford, York County, Maine, US 16,193, 9 Ukuboza 1856, yashyizweho umukono ku wa 27 Ukwakira 1856. Ntiyasabye uburenganzira ku rugendo ruzamuka n’urumanuka cyangwa ku rugendo ruzenguruka biva ku murandasi unyeganyega buri kimwe ukwacyo; yasabye uburenganzira ku buryo butanga byombi icyarimwe. Inkoni izinze icapwe inyura mu mwobo w’impande enye isimbura umugozi wa vis we; pine, ikintu cyo kubikamo n’ibice bicapwe bisimbura ibindi. Ibicapwa bya FDM bigumana ibiryo mu mirongo y’ibyiciro byabyo, bityo byoze neza kandi ubisimbuze iyo byashaje.
