New Portable Pipe Cutting Machine
The necessity for a portable pipe-threading, cutting-off and reaming machine which can easily be removed to any part of the repair shop or taken to any place where work is to be performed is nized by all water works superintendents. a machine is being put out, thc principal features of which are, besides being port able, that it is demountable and has a self-contained grinder and t hr c e drives, motor, belt and hand, built into the machine. The machine, which is illustrated herewith, is made by the Williams Tool Corporation, Erie, Pa. It can be converted into a power unit in 21/2 minutes and by using a flexible shaft it will operate hand stocks up to and including eight inches. It is designed so that it can be knocked down in two minutes and thirty seconds and reassembled in less than four minutes. The special oil trough and cutting pan under the carriage can be lifted off allowing the carriage and head to slide off the ways. These can also be pulled out of head stock by slackening two tension screws, thus leaving only the pedestal and head stock as the unit, which two men can easily lift and move to any desired position.
The machine can be converted to belt drive by removing the motor belt and driving directly from a line or countershaft. In order to operate the machine by hand it is necessary to shift the gears to neutral postion when the crank handle can be fitted direct to the worm shaft which is direct connected to the spindle through worm and worm wheel with ballthrust which operates in oil. The capacity of the machine makes it possible to cut either right or left hand threads on pipe 1/4 to 2 inches and on bolts from 3/8 to 1 1/2 inches inclusive. The cutting off capacity covers the same sizes of pipe and bolts. The machine will ream the inside and chamfer the outside of pipe, inclusive, from 1/4 to 2 inches. The longest run thread at one chucking is 10 1/2inches.
