. The Street railway journal . ng and 6 ft.

To the back of the frameand running its entire length was a i-in. longitudinal shaft placed13 ins. below the top of the register boards, and having bearingson the five uprights. At the middle of this shaft was clamped ahorizontal wrought-iron driving lever 10 ins. long, which, by-means of a i^-in. x J^-in. connecting rod, was connected with a crank having a distance of 2 ins. between the center of its shaftand the centei of the the crank run, this shaft being fastened rig-idly to the shaft of a pulley driven by power from the mill mechanism gave the longitudinal -diaft an oscillating motion,which was transmitted to each register by means of a verticalslotted lever clamped rigidly to the shift and a spring connecting. .CONTROLLER HANDLE IN OPERATION rod. The purpose of the spring connecting rod was to avoiddamaging the register in case its mechanism became locked. The rate of speed agreed upon was 300 registrations ,and the test was conducted twenty hours daily from 5 a. m. to1 a. m., during which time, however, certain hours were allowedfor repairs. As a result of the test, which was commenced and ended Sept. 20, the St. Louis register made the best showing. ♦ ♦♦ New High-Voltage Insulator Fred M. Locke, of Victor, N.
