J. F. Blyth & Co of Millwall, London
Established by James Frederick Blyth
1888 Took Limited Company status. Ironfounders and engineers.[1]
John Frederick Blyth (9 Oriel Villas, Sydenham) and George William Newall (14 First Avenue, Manor Park, Essex) patented a 'Motor Engine'[2]
1889 Makers of Newall's high speed enclosed steam engine. These were small single-acting engines with a novel feature: the gudgeon (wrist) pin served as the steam admission valve.[3]. On trials without a propellor, a small engine made for a 42 ft steam yacht ran at 1004 rpm ahead and 980 astern. It was expected to make 600 rpm in service at 90 psi steam pressure. An engine had already been running for two years to provide power in Blyth's works.
German patent no. 6816 granted to G W Newall, February 2, 1889. Drawings show a version of the high speed engine having, in addition to the rotary distributor in the gudgeon pin, a slide valve in the piston head and an externally adjustable slide in the side of the piston.[4]
