BEAN S MACHINE V presses the metal, rendering it homogenous throughout and ofgreater tensile strength. The patent is dated April 19, 1887, and numbered 361,479. Spark-Arrester for Locomotives. The accompanying illustrations represent a spark-arrester,recently patented by William Wilson, of Bloomington, will be seen from the engravings, a wire netting is placedin the smoke-box, instead of the stack, and is in the form of afrustum of a cone, extending from the top of the exhaust noz-zle to the bottom of the stack. In front of the tubes, and ex-tending below the top of the exhaust nozzle is a deflector E,and another deflector F is placed in front of and below thenozzle. Appended to the lower part of the smoke-box is areceptacle or spark-box G, the opening into which can beclosed by a valve. From this spark-box two pipes, ///, runback to the fire-box, where they connect with the pipes / KI.,running along the front and side of the fire-box. a
