The slide valve allows water from the ejection pump to enter the tube.

Before this patent, there were problems with slide valves which suffered excessive wear.

The principal problem was lubrication of slide valves with the higher temperatures.

The slide valves were worked by an outside Allan valve gear.

The slide valve is controlled by a fixed crank on the crankshaft.

They had slide valves on top and outside Stephenson link motion.

On simple slide valves, no opposing steam admission is possible due to the way they are constructed.

The saturated steam drive was on the outside and had slide valves.

The design was conservative, using slide valves and spur wheel gear drive transmission.

The steam cut-off point when using a slide valve is less than 30% of the stroke.
