Invention of Electric Drills & Cordless Drills

Electric xyaumtau ua raws li qhov tshwm sim ntawm qhov tseem ceeb tom ntej hauv kev siv tshuab drilling, lub tshuab hluav taws xob. Kev xyaum hluav taws xob tau tsim nyob rau xyoo 1889 los ntawm Arthur James Arnot thiab William Blanch Brain ntawm Melbourne, Australia.

Wilhem thiab Carl Fein ntawm Stuttgart, lub teb chaws Yelemees, tau tsim thawj lub tshuab nqa nqa nqa tau xyaum hauv xyoo 1895. Black & Decker tau tsim thawj lub cim-hloov, rab yaj phom-grip portable laum hauv xyoo 1917. Qhov no tau cim qhov pib ntawm lub sijhawm niaj hnub drilling. Hluav taws xob xyaum tau tsim nyob rau hauv ntau hom thiab ntau thiab tsawg thoob plaws hauv lub xyoo pua xeem rau ntau daim ntawv thov.

Leej twg yog tus tsim thawj Cordless Laum?

Yuav luag tag nrho cov kev xyaum cordless niaj hnub no tau nqis los ntawm S. Duncan Black thiab Alonzo Decker's 1917 patent rau lub tshuab nqa nqa nqa, uas ua rau lub zog niaj hnub kev lag luam nthuav dav. Lub tuam txhab uas lawv koom ua ke, Black & Decker, tau los ua tus thawj coj hauv ntiaj teb raws li cov neeg koom tes txuas ntxiv tsim kho tshiab, suav nrog thawj kab ntawm cov cuab yeej hluav taws xob tsim los rau cov neeg siv khoom hauv tsev.

Raws li 23-xyoo-laus cov neeg ua haujlwm ntawm Rowland Telegraph Co., Dub, tus kws sau ntawv, thiab Decker, lub tuam txhab tsim khoom thiab tuag, tau ntsib xyoo 1906. Plaub xyoos tom qab ntawd, Dub tau muag nws lub tsheb rau $ 600 thiab nrhiav tau lub khw me me hauv Baltimore. nrog tus nqi sib npaug los ntawm Decker. Lub tuam txhab tshiab thawj zaug tsom mus rau kev txhim kho thiab tsim lwm tus neeg txoj kev tsim kho tshiab. Lawv npaj los tsim thiab tsim lawv tus kheej cov khoom tom qab ua tiav, thiab lawv thawj zaug yog lub tshuab cua compressor rau cov tswv tsheb los sau lawv cov log tsheb.

Thaum xav txog kev yuav ib rab phom tsis siv neeg Colt.45, Dub thiab Decker pom tau hais tias ob peb lub peev xwm tuaj yeem muaj txiaj ntsig zoo rau kev xyaum cordless. Nyob rau hauv 1914, lawv tau tsim ib rab yaj phom tuav thiab txhais tes hloov uas tso cai rau ib leeg tes tswj fais fab, thiab nyob rau hauv 1916, lawv pib loj-tsim lawv xyaum.
