A framing machine that is claimed to do more and bet-ter work than six me,chanics can do with hand tools isillustrated below. This machine consists of a small car,38-in. wheel base, 2-ft. gage, 20-in. wheels, on which ismounted a 4 H. P. gasoline engine. In front of thisengine is hinged a cast steel arm, 4 ft. long, supportinga 10-in. grooving head. This arm can be adjusted up ordown by a screw passing through its center and bear-ing on a steel plate near the front of the car. Attachedto this plate are two wing plates, one on each side of thecutter arm, which serve as a support to the arm. By the. Portable Engine-Driven Framing IVIachine. use of a bolt passing through slotted holes in these platesthe arm may be clamped in any desired position. A IVg-in. mandrel supports the cutter head at one side of theouter end of the arm; on the other side is attached apulley which is belted to the engine. The illustrationalso shows the material car which has 10 ft. wheel baseand 2 ft. guage. The ties, two at a time, are loaded on thiscar which is placed at right angles to the machine timber is scribed across to give location of daps, andthe work proceeds as follows: By operating a lever shownclamped to the front wheel of the small car the wholemachine is pushed forward or backward, the arm pass-ing over the work in a horizontal line and at such depth making a convenient rig for sawing form lumber, build-ing stock, splitting wedges, etc. The machine described above is manufactured by J. , Grand Rapids, Mich.
