A 1930s Pacific Marine Pump Rig
This 1930s Pacific Marine pump is powered by two Johnson outboard engines paired together to create a four-cylinder power plant for running a pump.
Contributor Herb Higginbottom sends in some interesting pictures this month of an engine and pump rig built sometime in the 1930s by the Fire Equipment Division of Pacific Marine Supply Co., Seattle, Wash.
This four-cylinder engine is apparently built up from two Johnson outboard, water-cooled, opposed two-cylinder engines.
'The water jacket on one-cylinder was broken,' Herb says, 'so I welded on a new piece. Two pistons were stuck. I broke them loose by filling the cylinders with oil and fitting an adapter in the spark plug hole. Then I used a grease gun to break them loose. We were lucky this time, as the pistons were above the exhaust ports.'

1. Fill tank with a mixture of gasoline and oil. Zerolene No. 5, manufactured by the Standard Oil Co. of California, or Gargoyle Mobile Oil A. One-half pint oil to a gallon of gasoline. Shake well before pouring - for the first 20 hours of running a new engine use three-quarters pint of oil to a gallon of gasoline.
2. Fill pump pilot gears with oil through plug openings to a right level. Fill grease cups.
3. Squirt oil on pump rotors, then connect hose.
4. Open water valve on pump to engine, open valve on gas tank.
5. Place timing lever in center, open carburetor needle valve one turn. Push carburetor lever down to choke, wind on starting cord. Hold down float pin in carburetor until gas floods. Step on lugs on engine base and pull smartly on cord. Flood and pull again until motor starts. Notice: Do not flood a warm engine.
6. When motor starts, place carburetor lever in center. Adjusting timing lever against engine rotation. Adjust needle valve. Experiment to find best adjustment as engine warms up.
7. Notice: See that water flows from four discharge pipes all the time engine is running.
8. To slow down, retard timer and raise carburetor lever.
9. To stop, push in button on advance lever.
Bill Simmons sends this picture of a saw in operation in Germany in 1945. The tractor appears to be homemade, and power comes from a gas engine of unknown make. Has anyone ever seen a unit like this before?
Bill Simmons is wondering if anyone might be able to shed some light on an engine and tractor he remembers watching run back in 1945. 'The enclosed photo was taken in Kessel, Germany, in 1945, when I served in the U.S. Air Force there,' Bill writes. 'A while back I was looking through my old Air Force pictures and ran across it.
'I personally watched as the wood was sawed, but it did not at the time occur to me to look for the tractor name. Perhaps someone in your reading audience can identify the tractor. I would be interested if they could. Thanks for any assistance you may be able to give.'
