Bartlett at 569 Broadway in Manhattan in New York, in 1872. Bartlett claimed his street lamps cost less than one quarter of the twenty-five dollars which ''The New York Times'' had reported a competitor claimed they cost. The ''Times'' responded that the New York City Parks Department said that they actually paid more than that for each lamp, including the post and frame, that they used in parks, streets, and elsewhere.〔 The city of Troy, New York used the lamps beginning in 1872 to replace older models when they wore out.〔Classified Ad 2-No Title, March 28, 1874, p. 7.〕 ==Advantages of use== According to Bartlett, a portion of the economy of the Bartlett Street Lamps was derived from the iron frames used in their construction. Other efficient qualities included a greater thickness of glass and less need for repair. Unless an object collided with a Bartlett Street Lamp with sufficient force, it would likely glance off of it. Likewise, drops of rain did not affect them after they were lighted. The ''Times'' disputed those contentions, saying the lamps were frequently cracked or broken.〔(The Bartlett Street-Lamps ), letter to the editor and response, ''The New York Times'', February 4, 1872, p. 5.〕 Lamplighters preferred them because they were easy to light and clean. Bartlett Street Lamps diffused light nicely, according to an advertisement.〔Classified Ad 8-No Title, ''The New York Times'', March 30, 1874, p. 5.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bartlett Street Lamps」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
