One of the most remarkable features about this in-jector is its grading capacity. The best injectors heretoforemanufactured have a grading capacity of only about 40 to 50per cent., while the minimum capacity of the Internationalis 66J per cent, less than the maximum capacity of the samesize. The parts are made interchangeable, and are all easily.

PORTABLE CRANK PIN TURNING MACHINE. This machine is of a very simple design, ami works mosteffectively. It is so constructed thai it will turn either longor short pins that arc collarlcss orhave a collar, and that, too, with-out the use of any offset tools. Inorder that the work may be per-fectly true, the machine may belined cither with the face of the hubor with the bore of the wheel, andil will therefore run true with theoriginal pin. For turning the outerend of pins the tool is held closeto the main body of the machine,but for pins with two bearings anextension bar is used for reachingthe innerone. A large shell is usedto hold the workin
