The drawing above shows a very compact machine for cutting off, and making screw threads, on pipes from one to six inches diameter, an unusual range for machines of the kind. This is done with but two sets of double-end dies, equivalent to four sets, however, in so far as diameters.
The clamping mechanism is of a very simple kind, consisting of right and left geared screws operated by the handle at the side. The driving gearing, except the belt pulleys, is all housed in the main frame, secure from chips and dirt. The dies are opened and closed simultaneously by means of cams, and the longitudinal movement is performed by the hand wheel at the side.
The Armstrong Company are makers of all kinds of dies and apparatus for screw cutting, and seem in this machine to have reached the end of compactness and cost. |
