Last year, GEM readers Mac and Betty Sine came across a treasure trove of old photographs and manuals of Ingersoll-Rand industrial engines produced in the teens and 1920s. The materials are in the archives of the Dresser-Rand Company, Woodcliff Lake, N.J.

Working with officials at Dresser-Rand, the successor company to Ingersoll-Rand, Mac and Betty have secured permission to have some of these images reprinted in the pages of Gas Engine Magazine.

The quality of the images Mac and Betty have found varies, but some of them are nothing short of amazing, showing fine detail and, in some cases, giving a good sense of scale. Dresser-Rand calls these 'heritage' engines.

Photo #1 shows a shop picture (taken in the old Ingersoll-Rand plant in Painted Post, N.Y.) of a Ricardo combustion chamber Model XG integral gas engine/compressor. The power-end cylinder bores are 17 inches, stroke (both power and compressor) is 20 inches.

The XG was introduced in the mid-1920s and was first produced with a flat-type combustion chamber. Photo #2 shows an XG unit installed in a gas transmission plant (the company name and location of the plant are not identified). This unit has 18-inch bore power cylinders and 32-inch bore compressor cylinders.

Special thanks to Dresser-Rand Company for permission to print these photographs.
