Not illustrated. 1878 Excerpt: . that, when a piece of work is once set, any necessary number of holes may be bored without moving it. Some difference of opinion exists as to whether it is better to use horizontal or vertical machines for boring large work, such as the cylinders of marine and pumping or blowing engines. Vertical machines seem to be generally preferred, but in deciding upon the form of machine to be adopted the position the cylinder will afterwards occupy ought to be taken into consideration. A peculiar form of machine, called a vertical boring mill, is extensively used in the United States. An example of a mill of this kind, made at the Niles Tool Works, is shown in Fig 11. Vertical boring mills may be considered as surfacing lathes with horizontal face plates; they are used for doing a great deal of work that in this country would be done in the lathe, as its horizontal position renders it very convenient for setting and fixing heavy work upon the face plate. This is supported on a centre spindle, 12 inches in diameter, which works an adjustable steel foot step, that can be lowered to allow the face plate to rest on an annular bearing under its extreme outside edge, when a heavy piece of work is being operated upon. It will be seen that two tool-holders are placed on the cross slide, and are balanced by a counterweight attached to the end of a chain. The Clements driver shown on the face plate and the dead centre on the cross slide are used when the machine is employed for pulley turning, an operation for which these machines are well adapted. At the Cincinnati Exposition in 1872 a pulley 30 inches in diameter and 10 inches wide on the face, and of ordinary hard metal, was turned (two cuts being run over it), and had the edges trimmed in forty-two minutes by one of these.<
