Roller coaster |
Roller coaster In 1885, a U.S. patent for a gravity switchback railway was issued to La Marcus Adna Thompson of Coney Island, N.Y. (No. 332,762). In 1884, Thompson, the “Father of the Gravity Ride,” opened a 600-ft roller-coaster at Coney Island at 6-mph maximum. Its popularity enabled him to recoup his $1,600 investment in only three weeks. In this patent he described a railway on trestles with two parallel tracks undulating vertically. At the end of the first track, a switch automatically allowed the car to return on the second track. His design in an earlier patent (20 Jan 1885, No. 310,966) needed passengers to temporarily get out of the car at the end of the first track while assistants prepared it to return on the second track.) |
