Kuvugisha Amavuta n'Imbaraga z'Imbwa: Utuzingiti two ku Ruziga rwo Gukandagirwa Tuzunguza Umurambararo Ukoresha Igikoresho cyo Kuvugisha

"Iherezo ry'akaboko A, kuri E, rigenda rikanizwa n'akaboko kasohotse c, k'uruziga rukandagirwa, kugeza ubwo ritsimbutse cyangwa rikarenga hejuru y'akaboko kasohotse c, maze iherezo ry'hasi ry'akandi kaboko A rigahita rifatwa n'akandi kaboko kasohotse c, k'uruziga rukandagirwa ku ruhande rubangikanye narwo, rikagenda mu cyerekezo gihabanye n'icy'akaboko ka mbere A…"

Mu mbaho z'ibiti za mm 70 z'umubyimba (square timber), kora urubuga rwa mm 2470 kuri mm 2300: shyiramo imbaho ebyiri z'impande z'uburebure bwa mm 2300, n'imbaho ebyiri z'impera n'iyo hagati z'uburebure bwa mm 2330 ziri hagati yazo, ubizirikishe imisumari y'imirindankuyo (screws) ya santimetero 3. Shyira ku butaka imbere igiti cy'urufatiro cya mm 2470, ugihuze n'igiti cy'imbere ukoresheje imitambiko itatu ifite imitsindo (strap hinges). Shyira ibyuma bya beto munsi y'inguni zombi z'inyuma: buri gicuma cyongera ubuhengamire hafi dogere 5; dukoresha bitatu, bivamo dogere 14.3. Genzura ubuhengamire ukoresheje igikoresho gipima inguni (angle finder).

Komatanya kandi ushyireho imisumari y'inyerera ibice bibiri bya pulanke (plywood) ya mm 18 ukore disiki ireshya na mm 1700, ku buryo imyenge y'igice cya kabiri inyura hejuru y'iy'igice cya mbere. Munsi yayo komatanya impeta ya mm 150 z'ubugari ku nkombe, n'igice cy'ikibanza (hub) cya mpande enye zingana na mm 300. Shyiraho imisumari y'inyerera ibiti munani bya pine (cleats) uhereye kuri mm 150 ukageza kuri mm 680 uvuye hagati, kugira ngo imbwa ibone aho ifata. Shyiraho boliti ya bearing imwe ya flange ku giti cyo hagati, indi ku kiraro kiri hejuru yacyo kuri mm 200; unyuze mu byo byombi no mu kibanza (hub) icyuma cy'axle cya mm 30 ugihagurike, hanyuma ugifatanye n'ikibanza (hub) na boliti inyura impande zombi ya M10.

Caho imitambiko itanu y'uburebure bwa mm 300 uyikuye ku giti. Buri umwe uwufatishe hejuru y'uruziga ukoresheje bolt ebyiri za carriage, uhereye kuri mm 700 werekeza hanze ukageza kuri mm 150 hirya y'impera y'uruziga, buri umwe ukurikiye undi ku nguni ya dogere 72.

Shyira inkingi ireshya na mm 1340 hagati ya buri rubaho rwo ku ruhande, uyifatishe imbere n'inyuma imigozi ya santimetero 3 (inch 3). Fatisha bulone umuzingo (flange bearing) ku maso y'imbere ya buri nkingi, kuri mm 1260 uvuye hasi, kandi uhinguze umwobo wa mm 40 unyuze mu nkingi y'ibumoso. Anyuza muri byo ishoka ya mm 30 ireshya na mm 2655. Imanika ukuboko kureshya na mm 960 ku ishoka kuri buri ruhande, ahagana imbere hako hakaba hari mm 20 hanze y'urugara, naho ikirenge cyako kikaba kiri mm 45 munsi y'impera z'hejuru z'ibisunika (tappets), ukakifatisha ku ishoka na bulone inyuranamo.

Hambira akaboko F ka mm 760 ku mugozi w'inyuma y'inkingi y'ibumoso, ukagashyira mu mfuruka ya dogere 90 n'uwo mugozi. Kobora umwobo mm 330 ku mpande zombi z'umugozi kugira ngo ushyireho ingingo H. Ca ibiti by'ipine mo imiti ibiri G ya mm 45 kuri 20, uyicukure imyobo myinshi, hanyuma uhuze buri muti ku mpera imwe ya F ukoresheje ibolu ya M10. Hamba imbaho ebyiri zihuranye zifite uburebure bwa mm 240 ku nsi ya buri muti nk'ikiyobora amata, ukate umwenge mu mupfundikizo wa buri ndobo, hanyuma ushyire ndobo munsi ya buri muti kugira ngo icyo kiyobora gihagarare mm 40 hejuru y'ubutaka.

Shinga igiti gihagaze ku mugogo w'inyuma, kuri mm 450 iburyo bw'ikigo, maze ukurure umurambararo uturutse kuri cyo uwuhitishe hejuru y'uruziga, igice cyawo cyo hasi kikaba kiri kuri mm 430 hejuru y'uruziga, ugarukire kuri mm 450 inyuma y'ikigo cy'uruziga; uwuteremo umutambiko uwufashe munsi. Shyira ikariso ifite ijisho (eye bolt) munsi y'iherezo ry'umurambararo kugira ngo bahambireho umukoba w'imbwa.

Koresha umukandara w'imbwa (harness), ntukoreshe agakoresho gashyirwa ku ijosi (collar), uwufatishe ku gafuni k'icyuma (eye bolt) kugira ngo imbwa ihagarare iburyo bw'umurongo wo hagati ireba hejuru ku musozi. Tangira ku gatsika kamwe ukoresha ibiryo bito byo kuyihemba kugeza igenda utuje. Suka litiro nka 9 z'amavuta y'amasosi (heavy cream) afite ubushyuhe bwa 15 °C mu ndobo imwe imwe, ukoresheje termometero kugira ngo ubipime, hanyuma ufunge ibipfundikizo. Pima igihe igikorwa kimara ukoresheje sitopuwashi (stopwatch). Iyo amavuta abonetse, suka amata y'ikivuguto (buttermilk), woze amavuta mu mazi akonje kugeza amazi asohoka asa neza, uvange mo agafu k'umunyu, hanyuma uyapime.

**Addison G. Brush** wa Great Bend, mu Karere ka Susquehanna, Pennsylvania, US 20,545, 15 Kamena 1858, "Operating Churns". Yakoze uruziga rwo gukandagirwa rurushaho kuremera ku nkengero cyangwa hafi yazo kugira ngo urugendo rwarwo rutuze kandi rungane, agena uburebure bw'urugendo akoresheje uburebure bw'ukuboko F, gushobora gukoresha ibyuma bibiri byo kuvugamo amata, kandi yongera imbaraga n'umuvuduko w'urugendo azamura uruhande rw'ikadiri. Yasabiye uburenganzira ku rubuga ruzenguruka rufite utwuma tuzamura (tappets) dukoresha dasher binyuze mu maboko A, A, F n'umutambiko B. Ntiyatanze ingano: izacu, igihe cy'utwuma dutanu tuzamura, umutambiko w'icyuma (steel) uri mu bikoresho bifata mu cyimbo cya gudgeons ze, umutambiko w'agafata (dog bar) n'indobo ni ibyacu. Inkoni G yegama nka dogere 2 hejuru y'urugendo, bityo reka imyenge y'umupfundikizo ibe yagutse.
