Ohio Machine Tool Works was the predecessor to Lodge & Shipley Machine Tool Co.
Special Patent Motor Gear Lathe.
We herewith illustrate a new machine tool, invented and designed by Mr. Wm. Lodge of the Ohio Machine Tool Works, late vice-president and general manager of the Lodge & Davis Machine Tool Company, Cincinnati, O.
It is the outcome of many years’ close and steady application in the shop, where endeavors constantly being made to enable an ordinary engine lathe to do higher duty. These attempts enable the designer to discover many features of weakness in the engine lathe as now built, discrepancies appeared the most glaring in lack of power and rigidity. Small spindles are only for light work, such as la usually done between centers. What mechanic has not found time after time, the attempt to turn large diameters on work suspended between slender centers has been a constant source of vexation and annoyance, consuming an endless amount of time and in the end producing unsatisfactory results? In these days of sharp competition, the efforts of some of the best mechanics in the country are constantly directed to devising special machinery and tools for producing machine work of excellent quality with great rapidity. Our illustration shows a lathe containing many of the elements desired. When made of 26" swing it is of special value to concerns manufacturing pulleys as a business, or who have large quantities of blank gears to bore and turn.
As a boring lathe alone, it is of great value, and on account of its great stiffness will do heavy boring with much greater facility than the ordinary boring lathe. It is of great value to engine builders and capable of performing three operations at one time on large quantities of work pertaining to the detail of engines, either Corliss or slide valve. The two saddles carrying the tools may be used in a similar manner that box tools are now used for large work and their great rigidity, and the fact of cutting on both sides at once will produce given diameters either straight or taper with heavy Musket steel tools that do not require regrinding but once a day on account of the great amount of metal backing up the cutting edges, the tools intended to be used being ¾”x 1 ½”, steel. Care has been taken to incorporate all the power and stiffness such a machine requires. They have carefully avoided any attempt to stretch its swing beyond a point where it weakens its usefulness. It is 26" swing and has three times the power of a 26" engine lathe, and while a cone pulley of ample dimensions is used, it will be seen that a much larger one may be used, when the work in hand requires it. In order that the conditions may be the very best under the most severe work, they have designed the bed so as to be cast all in one piece, from the floor to the center of the spindle bearings. The slides, upon which the saddles move, are also part of the bed. The feeds for saddles and boring slide are obtained from main driving shaft with worms and frictions and are very substantial.
The peculiar construction for obtaining tapers, permits of forms and shapes to be readily made from a forming plate of almost any design.
Boring bars take a bearing in main spindle, and, where very long, may be put in position either from back end of boring slide, or through the spindle which has 3 3/4" hole clear through. It has every convenience as a first class chucking lathe, and is remarkably efficient for this purpose on account of its great stiffness, and by the addition of rest and tool holder, which they will furnish for $25 extra, it makes a good cutting-off machine. Weight, 4000 pounds.
