Famous quotes containing the words patent and/or drawing:
“The cigar-box which the European calls a lift needs but to be compared with our elevators to be appreciated. The lift stops to reflect between floors. That is all right in a hearse, but not in elevators. The American elevator acts like the mans patent purgeit works”
—Mark Twain [Samuel Langhorne Clemens] (18351910)
“These native villages are as unchanging as the woman in one of their stories. When she was called before a local justice he asked her age. I have 45 years. But, said the justice, you were forty-five when you appeared before me two years ago. Señor Judge, she replied proudly, drawing herself to her full height, I am not of those who are one thing today and another tomorrow!”
—State of New Mexico, U.S. public relief program (1935-1943)
