BESSEMER - STRUTHERS WELLS
This is a large Bessemer cylinder with the hit and miss governor mounted
on the commercial Struthers Wells, of Warren, PA, frame.
Note the disc crankshaft.
It pumped a rod line power just south of Warren, PA.
BOARDMAN CONVERSION TO MONITOR
This is another version of half breed where the steam cylinder was
converted to gas. It is a
Robert Boardman, of Oil City, PA, four-cycle conversion to a Monitor
steam engine built in Erie, PA.
It was used near Pithole, PA.
INNIS - INNIS
This is probably not a half breed but a factory “economy” model.
Some times makers would use their own conversion cylinders on
their steam frames to do this.
Both the cylinder and frame are Innis built by Oil Well Supply of
Oil City, PA.
This engine was found in the old OWS grounds.
SHEFFER - STRUTHERS WELLS
This unusual four-cycle, hit and miss cylinder was built by Sheffer of
Emlenton, PA. They were a very small maker and few survived.
It is on a S W steam frame made in Warren, PA.
It pumped an oil lease near Emlenton.
