Itclaims the combination of a dynamo, an overhead conductor, a car withan electric motor connected with the car axle, a hand regulator on thecar, an upward pressing grooved contact connecting the traveling vehiclewith said conductor, and a return circuit through the rails. Both thesepatents were filed in 1SS6. Electric railway patents and trolley patentsseem to be getting into a hopeless tangle that will probably never bestraightened out. 498,074. No. 497.^34-No. 497,834 is a device to alleviate the hammering of rail joints bybridging the crack between tlie rail ends with two flat steel springs, ashere shown. WM. m t-k ^1». BjSi,&s^
