J. I. Case Automatic Pedestal Engine.
It is made in three main varieties: The Pedestal Engine, the Bracket Engine, and the Hanger Engine. The illustration represents the [Pedestal type], the upright frame of which is cast in one piece, and encloses and protects the principal moving parts, its lower part being a reservoir for oil, into which the crank-pin dips at every revolution, affording a simple and efficient means of lubrication.
The piston is connected directly with the crank shaft, thus doing away with the cross-head, wrist-pin and guides. The piston being thus connected at one end to the crank-pin, it travels back and forth at its other extremity through the bore of the cylinder. The latter by reason of its shape is free to turn in its casing, and is therefore rocked by the vibrating piston rod through an arc sufficient to open and close the steam and exhaust ports on its face.
The cut-off valve is of the plug type, and receives its motion from the shaft cut-off governor, attached to the balance wheel.
The center crank shaft runs in two large bearings which are bolted securely to the side of the frame. Access to the inside of the frame can be had by taking off the plates from either side.
The J. I. Case High Speed Engines range in size from 2½ to 25 horse power, the speed of which ranges from 900 down to 550 revolutions per minute, and can be used in any capacity.
STEAM ENGINES.
All styles of engines both large and small should receive proper attention. All the vibrating and moving parts should be kept well oiled and free from grit and dirt. If this is neglected, the friction of the moving parts will soon wear away the metal and induce pounding and cause what is called “lost motion,” which detracts greatly from the power of the engine, and if allowed to run in this condition will soon necessitate large expense for repairs and shorten the life of the engine.
Tighten all the boxes as they wear, being careful not to get them too tight. Keep the piston rod and valve rod well packed with a good quality of soft packing. Keep the valve or valves set properly to give the required amount of lap and lead and an equal cut-off at the end of each stroke whether working in full gear or notched up.
Keep the cross-head shoes fitted properly in the guides, being careful to keep the piston rod in line. If the above instructions are followed, your engine will run smoothly and do good service.
