Description:Reverse section of portable 'sun & planet' engine for Reynolds & Co., Ketley, Shropshire.
Reynolds & Co. ordered two of these highly unusual engines for winding coal from mines. The engines were of 3 horses power, with 10 inch cylinders and 3 foot strokes. The drawing shows the engine mounted on a 4-wheeled truck, with the winding barrel at the front and the boiler at the back. This was one of the first small engines made by Boulton & Watt.
