Marine Engineering News, June 1st, 1876:

“When from any cause it becomes desirable to put a screw steamer under sail alone, a considerable diminution of speed is occasioned by the drag of the propeller through the water. Various means have been devised to remedy this evil such as gear for hoisting the propeller entirely out of the water, or use of a donkey engine to keep gradually revolving; and in addition, various plans have been suggested for feathering the propeller blades. Amongst the latter, that which we now illustrate of Mr H. S. Eyre’s, seems to possess the very important qualities of simplicity and efficiency, and mechanically to recommend itself for adoption.”

Engineering – The Field, April 21st, 1877:

“In Yachts supplied with auxiliary steam power, a good feathering screw is of the utmost advantage. We have recently had the opportunity of inspecting such a screw, invented by Mr. H. S. Eyre. It can be applied as shown to a three-bladed screw, and the blades are brought “fore and aft,” by what is really a very simple contrivance, although it looks rather complicated from the engraving. 

The Mining World and Engineering Record, April 28th:

Now to Yachts furnished with steam-power, a good feathering screw is decidedly a desideratum; and what claims to be an improvement upon anything of the kind yet put before the public has been invented by Mr. H. S. Eyre.
