LOW WATER ALARM.
A low water alarm is an instrument attached to a boiler, and so arranged and constructed that when the water in the boiler gets to a certain level, whereby it is becoming dangerously low, the alarm is given by the blowing of a whistle or ringing of a bell.
J. I. CASE AUTOMATIC HIGH SPEED ENGINE.
This style of Automatic Engines combines simplicity, compactness, direct action, lightness of moving parts, automatic lubrication, and perfect regulation.
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.
