Excerpt from Transactions of the Royal Scottish Society of Arts, 1908, Vol. 18: Part II Another clever device by the use of magnetism I am able to show you by the kindness of Messrs Middleton and Townsend. Here gears are still used, but they are not changed by one set being unmeshed and another meshed. They all remain in mesh, but each has a clutch of its own, worked magnetically, so that the wheels do not revolve, except those of the particular set which the clutch is made to hold by being magnetised. As regards such vehicles, the introduction of a system similar to those I have referred to, by which changes of speed are made by the use of electrical appliances, would, if it be proved practical, be of great value. Great progress has also been made in the production of efficient vehicles for conveyance of goods. Here, again, the question of cost of transit per mile has been solved favourably for the power vehicle. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
