Description: |
| Abstract:
The object of my invention is to provide means by which a compound engine may be easily and quickly changed to a simple engine using initial-pressure steam in both cylinders, and vice versa. A further object of my invention is to compactly arrange the shifting mechanism for use in connection with portable engines, such as traction-engines, and to provide means by which the exhaust-steam may be caused to heat the feed-water.
Claim:
In a compound engine, the combination with the high and low pressure cylinders, of a receiver, receiving the exhaust from the high-pressure cylinder, a feed-water heater receiving exhaust from the low-pressure cylinder, a valve-chamber, a port leading from said chamber to the heater, a high-pressure passage leading into said chamber, and a valve mounted in said chamber, the said valve arranged to be thrown so as to cut off the heater from the receiver and allow communication between the receiver and low-pressure cylinder, or to connect the receiver and heater and allow communication between the high-pressure passage and the low-pressure cylinder. |
