Scale model of a 100 inch driving wheel lathe produced by Niles Tool Works out of Hamilton Ohio, based on drawings from their 1891 catalog of machine tools.
"Driving wheel lathes
These lathes all have two heads, face plates and carriages for turning a pair of drivers on their axles at the same time. They have ample power to carry two heavy cuts simultaneously.
The face plates may be driven together or separately, as desired, and at the same or different speeds. They are made of sufficient diameter to afford clamping room for tires, to allow for boring.
The main spindles are of extra large diameter, with large and long bearings. Each main spindle has an internal sliding spindle with sufficient traverse to clear the longest crank pins.
The driving shaft is a solid steel forging, extra large, free from torsion, and hence insuring a great steadiness of motion while the Lathe is taking heavy cuts. All gearing, including the large face plate gear, is cut from the solid, insuring the full bearing of the teeth, and smooth steady running of the Lathe.
The face plate gears are not cast solid with the face plates, but are securely bolted to them, and may, in case of accident, be readily replaced without the necessity of replacing also the face plates.
The bed is triple web, of great width and depth. The front section forming the slides for the carriages is carried up to secure great stiffness at the point where the strain of the cut is taken, and to permit the use of very short, stiff tool rests.
The feeds are automatic, and arranged by a special device to secure proper speeds for turning both tires and journals.
The right hand head is arranged to slide, to accommodate axles of different length. It is operated by powerful hand gearing."
