The table annexed to the plate shows the result of ex-periments made by Mr. Cheret, Superintendent of theOrleans Railway Company. Tests made by the Eastern. Railway Company and the International Sleeping-CarCompany have given about the same results, and serve toconfirm the qualities and superiority of this invention. Comparing the results he obtained with this type ofwheel, to the results obtained with spoked-wheels andcommon disk-wheels with straight or rounded projec-tions, it is evident that the ribbed disk-wheel invented byMr. Arbel is much superior to the wheels heretoforemade; and, on account of the success achieved by theArbel wheel, several railway companies have just deter-mined to adopt it as the standard (or all their passengercars. Now that the use of continuous brakes is very com-mon, there is a demand for an article capable of thor-oughly resisting heavy strains and having absolute rigidity. In these respects, the new wheel, it is claimed, has all thequalities which could be desired. C. , May 6th. 1SS5.
