One of Manley Oil Company's jack-line oilfields was located on a hillside north of downtown Los Angeles and just west of Chinatown. When I took these photos in June 1970, the jack-line oil wells were still in operation, pumping crude oil as they had for decades. Los Angeles city hall appears in the background of the first two pictures showing just how close to downtown this obsolescent operation was.
The powerhouse for this operation is the building on the hill to the right of the picture. The jack-line cable from the power house to the well in the distance can be clearly seen. The collected oil was taken away by trucks which loaded from the pipe just to the left of the well. The jack-line that comes from the left side of the power house crossed a public street to reach its well, so it is suspended from a second cable by ropes to keep it from sagging.
This is a close-up of another well in this oilfield. This one was located to the north of the power house at the end of the "catenary" jack-line. This little operation was located in a residential neighborhood which included the modest home in the background.
