J.W. Martin, of Taladega, Ala., has invented an improvement in reaction water wheels, to relieve the lower gudgeon of the shaft from undue friction and load by weight of water after it has acted upon the buckets. The improvement is to prevent up-lift by under pressure of water, and also down pressure on the shaft. The wheel is open at top and bottom, and the periphery is connected to the shaft by arms, so that no water can lodge in the wheel, whether it may be let in at top or bottom. Measures have been taken to secure a patent.
