of this boiler over fire box extends beyond the back head. To this

extension is bolted the two brackets containing the bearings for the

main axle and cross shaft.

The traction wheels are of the wrought rim steel spoke type, with high

mud cleats bolted diagonally across the entire width of tire.

The front axle is supplied with a ball-bearing bolster, which supports

the front end of boiler. The engine has the Friction Clutch, Link

Reverse Gear, Long Heater, Independent Pump, Injector, Water Tank

on side, Foot Board with Tool Boxes attached, and all necessary

attachments and fittings to make a complete traction engine, and one

the straight stack and extension front has a spark arrester on the

inside.
