Jack Fesco

Shown in Jack M. Fesco and his 3/4 inch scale Southern Pacific Mountain type locomotive. She is a coal burner and runs on 100 pounds of steam that is super-heated.

There are Torrington needle point bearings on the drivers and rods. Other bearings used are Fafner ball bearings Nathan mechanical Lubricator and Boiler Check are used and 2 Consolidated saftey valves.

The dynamo is of the Otha Hege design. She has a front end throttle, and a multiple type cooper boiler, smoke box and jacket monel.

The other pictures shown are of a booster feed water pump, built by Jack.

The pump has an axle gear of 3/4 inch diameter and the eccentric gear is 1 inch in diameter. The cylinder has a 1/4 inch bore and a 1-1/4 inch stroke and is enclosed in a housing packed with a lubricant.

The water enters at the left manifold and discharges via the right manifold through the ball joints and then under the right running board to the boiler check.

A by-pass valve is installed, which is not shown in picture, in order to by-pass the water to the tank in case it floods the boiler.

The ball joints are real, and provide for flexibility such as when rounding a curve.
