f mechanics, by hisclever adaptation of air to the transfertable drive. It was he who devised the table, on which is mounted an air reser-voir 2.75 feet in diameter by 9 feet long,with a capacity of 53 cubic feet. In thecab is an engineers brake valve, piped tothe engines, and also to the reservoir andcharging mechanism. The charging device consists of a smallcylinder placed at one end of the table,centrally between the rails. The pistonrod of this cylinder is hollow for a portionof its length, and has on its outer end aspherical rubber gasket with a small pihtun of the charging cylinder, and alsoseen to have a small valve opening inwardand held to its seat by the pressure withinthe supply pipes. In the operation of charging the reser-\oir (and this can be done at any pointwithin the length of the pit), the en-gineers valve is turned to admit air to thecharging cylinder, forcing out its pistonto a connection with valve of the main (Continued en page 417.)

While tlie piston is i11 thispo ition, the rubber gasket makes an aiitight joint on the face of the valve, andthe hollow projection on the center of thepiston engages with the automaticallyclosing valve, thus forcing it off its seat,allowing the air to pass from the supplypipe through the hollow piston into there ervoir. A check is shown between thepiston and the pipe to the reservoir, to re-tain the pressure in the latter when air isexhausted from the charging cylinder, inorder to break the connection with themain air pipe after charging; the outwardclosing valve performs a like service forthe main pipe at the same instant. General Foreman Elvin states thathis little engines, with their ioo poundsair pressure, will take the table and a135.000-pound consolidation engine, mak-ing a total weight of about 150.000pounds, and traverse the length of the
