Abstract

25,920. Pernot, C. Jan. 5, [date applied for under Patents Act, 1901]. Drawings to Specification. Driving-chains.-Relates to chain gearing in which the teeth of each chain-wheel are fixed to a flexible member arranged to work in circles of varying diameter. These teeth are cut away and carried on trunnions, so that an ordinary roller chain can be used for transmission. The Specification in the original form as published under the Act of 1901 comprises a modification in which an ordinary roller chain is used in the variable chainwheel. In this case, the transmission chain is composed of links in the shape of arches fitting over the rollers. This subject-matter does not appear in the Complete Specification as accepted.
