Volume Ten - Pre-Victorian to the present day - even more aspects - The Patent for the Penarth Slipway - 1881 . . .

Mr. James Leslie cont'd :

Within a year or two afterwards, with the view of dispensing with the reversing of the pitch-chain, he made some sketches of an endless pitch-chain, which he wished applied to the Dundee slip; but, from the buildings and machinery being all completed, it was found that the expense would be too great, and the idea was given up.

In 1849, he made for the Pacific Steam Navigation Company plans and specifications of a slip, proposed to be laid down at San Lorenzo, with an endless chain. That slip was never made ; but in 1851 the endless chain was, with his concurrence, adopted by Messrs. Morton for the Duke of Buocleuch’s slip at Granton.

That slip had an endless pitch-chain 60 feet in length, with three hump-backed links, D (Fig.5), in its length, having each three eyes, one on the back with a common single link, E, attached for coupling the uppermost chain rod.
