The Engine is suitable for all kinds of work where high speed and smooth running are required. It is correctly proportioned, especial attention having been given to distributing the metal along the lines of strain.
The Bed is made with a solid bottom and arranged to catch all drippings, which are conveyed to an exit which has been provided.
The Crank Shaft is cut from a solid forging of the best quality steel and is equipped with counterbalancing weights. The main bearings of the crank shaft are made especially large and strong and are provided with bronze quarter-boxes for adjustment.
The Connecting Rod is equipped with extra heavy phosphor bronze boxes at each end. The cross-head end is of the solid end type, while the crank pin end is of the strap type. Both brasses are adjusted by means of wedges.
The Crank Pin and Cross-Head Pin are long and of large diameter, giving very liberal wearing surfaces.
The Piston is the hollow head type and is provided with self-adjusting rings.
Other features are balance fly-wheel and eccentric keyed to the crank shaft.
The Boiler is made of open-hearth steel plates, thoroughly braced and stay-bolted to withstand a working pressure of 125 pounds. The fittings and fixtures comprise grates, water gauge, gauge cocks, steam gauge, safety valve, check and stop valves, blow-off valve, stack, whistle, injector attached, fly-wheel, pulley, oil cups, lubricator, throttle valve, automatic governor and belt. Ash pan furnished with rig on wheels; also tongue yoke, whiffletrees and brake.
The Grates regularly furnished are the plain type, but the Tupper or herringbone, or sawdust grates will be furnished, when preferred, without extra cost.
Boilers are regularly furnished with steel tubes, but can be furnished with Charcoal iron tubes, if desired at extra cost. |
