Sylvesterning katta akasi boʻyoqchi boʻlib ishlagan, ukasi esa Bostondagi Singer tikuv mashinalari fabrikasida mashinist sifatida ishlagan.

Sylvester Roper 1823-yil 24-noyabrda tugʻilgan. Yoshligidan u mexanik boʻlishga juda qiziqgan. 12 yoshida hech kimning yordamisiz bugʻ mashinasini yasagan. Bu ixtiro hozirda Francestown muzeyi koʻrgazmalar zalida saqlanadi. Roper Francestownni yoshligida tark etgan va dastlab Nashuada, keyin Manchester, New-York va Worcesterda mashinist boʻlib ishlagan. U 1845-yil 20-aprelda Rhode Islandning Providence shahrida Almira D. Hillga uylangan. 1854-yilda u Bostonga, Massachusets shtatiga koʻchib oʻtgan.

 Ixtirosi 
Taxminan u Bostonga kelganida, Roper oʻzining Handstitch tikuv mashinasini ixtiro qilgan. 1861-yilda u dvigatelini ixtiro qilgan va dvigatellari uchun bir nechta patentlar olgan. Sylvesterning dvigatel ustida tinimsiz ishlashi natijasida u 1 dan 4 ot kuchiga ega boʻlgan dvigatelni muvaffaqiyatli yaratgan. Roper fuqarolik urushi davrida Springfild qurol-yarogʻ omborida ishlagan. Roperning ishi oxir-oqibat mintaqaning boshqa ixtirochi va muhandislari, jumladan Elias Howe, Alvan Clark, Christopher Miner Spencerning eʼtiboriga tushgan. U 1896-yil 1-iyun kuni Cambridge shahrida mototsikl halokatidan vafot etgan.
