The 'Bisschop' Patent Gas Engine

THE 'BISSCHOP' PATENT GAS ENGINE.

8315 Amber Lane Newcastle, CA 95658

The Bisschop engine was first patented in 1871 by Alexis De Bisschop of Prussia. The engine produces 2 man-power or 1/3 HP at 110 RPM. It has a 4' bore with a 9' stroke. It has flame ignition and is a two cycle engine.

I first became interested in the Bisschop engine when I saw it in Wendel's book where it is listed as a Sombart. Going through my mind was the regret that I would never see one in iron. Then, on a tour to the British Isles and Scotland, I saw a five man-power Bisschop in a museum in Edinburgh. I was all over it, checking out its operation and taking pictures.

I then found some drawings in a book, on a two man-power, 4' bore, 1/3 HP Bisschop. The drawings only gave me one measurement to work with.

On my next gas engine trip to the East, I went to the Ford Museum in Dearborn, Michigan. There I found a two man-power, 1/3 HP Sombart.

Again I took pictures and measurements. With these measurements, I converted the drawings in the book to the dimensions I would need to make a full size engine some day.
